Headwear manufacturing glossary

3

3D puff

An embroidery technique in which satin stitches are sewn over a layer of foam so the design stands up from the fabric. Excess foam is torn away after stitching. It suits bold shapes and thick letters on firm, structured fronts, and is less suited to small text or fine detail.

A

Acrylic

A synthetic fiber widely used for knitted beanies. It is soft, light, holds bright colors well and is easy to care for. Compared with wool it is less breathable and less able to regulate temperature, and it can pill with heavy wear depending on yarn quality.

See also: Beanie, Merino, Gauge

Appliqué

A decoration method in which a piece of fabric is cut to shape, placed on the cap and secured with embroidery stitches around its edge. It covers large areas with fewer stitches than a full fill and allows contrasting textures, such as felt or twill, inside an embroidered outline.

AQL

Acceptance quality limit. A statistical sampling method used in final inspection. Based on lot size and an agreed inspection level, published tables set how many pieces are checked and how many defects of each class are allowed before the lot is rejected. Limits are agreed between buyer and supplier per order.

B

Beanie

A close-fitting knitted hat without a brim. Beanies are made cuffed or uncuffed, in rib or plain knit, sometimes with a pom on top. Common yarns include acrylic, merino, wool blends and recycled polyester. Logos are applied by embroidery, woven label, leather patch or knitted into the fabric.

See also: Cuff, Rib knit, Pom, Gauge

Brim

The projecting front part of a cap that shades the eyes, also called the peak or bill. It consists of an insert, usually plastic board, covered with fabric on top and underneath. Brims are flat or pre-curved, and the number of stitching rows on top is a style choice.

See also: Pre-curved brim, Sandwich brim, Undervisor

Brushed cotton

Cotton fabric, often twill, whose surface has been mechanically brushed to raise fine fibers. The result is a softer hand feel and a slightly matte, peached appearance. It is common on classic baseball caps and dad caps where comfort and a muted look are wanted.

See also: Twill, Dad cap, Washed (garment-washed)

Bucket hat

A soft hat with a round crown, a flat top panel and a downward-sloping brim that circles the head. The brim is usually stiffened with several rows of stitching rather than an insert. Variants include eyelets for ventilation, drawcords and reversible constructions with different fabrics inside and out.

See also: Crown, Eyelet, Toggle and drawcord

Buckram

A stiff woven interlining fused or sewn behind the front panels of a cap to hold them upright. Buckram is what makes a cap structured. Its stiffness can vary from soft to firm, which affects how crisp the front looks and how well it supports large or raised decoration.

See also: Structured, Unstructured, Crown profile

Button (squatchee)

The fabric-covered button at the top of a cap's crown where the panels meet. It covers the point where the panel seams converge and keeps them neat. It is usually covered in the main fabric or a contrast color, and it is absent on some knitted and bucket styles.

See also: Crown, Panel, Six-panel

C

Camp cap

A five-panel cap with a low, flat crown, a wide front panel and usually a flat or slightly curved brim. Camp caps are often unstructured, made in nylon or lightweight cotton, and closed with a strap and slide or a buckle. The seamless front suits a centered patch or logo.

See also: Five-panel, Unstructured, Strapback

Canvas

A sturdy plain-weave fabric, traditionally cotton, with a firm hand and a slightly coarse texture. On caps it gives a durable, workwear character and holds its shape well. Heavier canvas can be harder to embroider finely, so artwork detail may need to be adjusted.

See also: Twill, Five-panel, Washed (garment-washed)

Carton marking

The information printed or labeled on the outside of shipping cartons, such as order number, style, color, size breakdown, quantity, carton number, weights, dimensions and destination. Buyers usually supply a marking layout so goods can be received and stored without opening cartons.

See also: Polybag, Hang tag, Country of origin

Chain stitch

An embroidery stitch made of interlocking loops that form a chain-like line. It produces a textured, hand-crafted look and is used for script lettering and outlines, often in vintage-inspired designs. It needs specific equipment and is slower than standard flat embroidery for the same design.

See also: Flat embroidery, Digitizing, Satin stitch

Corduroy

A cut-pile cotton fabric with raised parallel ridges called wales. Wale count describes how many ridges fit across an inch: low counts give wide, bold ridges, and high counts give fine needlecord. Corduroy gives caps a soft, textured, seasonal look and suits embroidery and patches.

See also: Twill, Embroidered patch, Bucket hat

Country of origin

The country where a product is considered to have been made under the applicable customs rules. It determines import duties and labeling requirements in the destination market and must usually be marked on the product or its label. Rules for determining origin differ between trade regions.

See also: Incoterms, Woven label, Carton marking

Crown

The part of a cap or hat that covers the head, above the brim. On caps it is formed by sewn panels joined at the top under a button. Its height, shape and stiffness define the cap's profile and how it sits on the wearer.

See also: Panel, Crown profile, Button (squatchee)

Crown profile

The side-view shape of a cap's crown, usually described as low, mid or high. It reflects the height of the front panels and how steeply they rise. Because the terms are relative, profile is best specified with measurements such as front panel height and crown depth.

See also: Crown, Structured, Buckram

Cuff

The folded-up band at the lower edge of a beanie. A cuffed beanie has a double layer around the ears and forehead for warmth and a natural place for a woven label or patch. Uncuffed beanies have a single-layer edge and a slouchier or slimmer look.

See also: Beanie, Rib knit, Woven label

D

Dad cap

Informal name for a low-profile, unstructured six-panel cap with a pre-curved brim, usually in soft or washed cotton twill and closed with a fabric or leather strap. It has a relaxed, worn-in look and suits compact flat embroidery on the front.

See also: Unstructured, Crown profile, Strapback

Digitizing

Converting artwork into an embroidery file that tells the machine where and how to place each stitch. A digitizer sets stitch types, direction, density, underlay and sequence. Good digitizing adapts the design to fabric and cap shape, and it largely determines how clean the finished embroidery looks.

See also: Stitch count, Fill stitch (tatami), Satin stitch

E

Embroidered patch

A badge made by embroidering a design onto a backing fabric, then cutting it to shape with a finished edge, often a merrowed border. It is sewn or heat-applied to the cap. Patches allow raised texture and dense color and can be reused across several styles.

See also: Woven patch, PVC patch, Leather patch

Eyelet

A small ventilation hole in a cap panel, finished either with embroidered stitching around the edge or with a metal grommet. Six-panel caps typically have one eyelet per panel. Performance caps may replace eyelets with laser-cut perforations for wider airflow.

See also: Panel, Laser perforation, Bucket hat

F

Fill stitch (tatami)

An embroidery stitch used to cover large areas with rows of short running stitches in a staggered pattern. Tatami gives a flat, even, textured surface and is more stable over wide shapes than long satin stitches. Fill direction and density affect sheen and how the fabric puckers.

See also: Satin stitch, Stitch count, Digitizing

Fitted

A cap with a closed back and no adjustable closure, made in specific head sizes. Fit comes from the pattern size and, in some styles, an elastic stretch band built into the sweatband. Fitted programs require a size breakdown in the order.

See also: Stretch-fit band, Sweatband, Snapback

Five-panel

A cap built from five panels: one wide front panel without a center seam, two side panels and two rear panels. The seamless front gives a clean surface for a centered logo or patch. Five-panel construction is common on camp caps and many trucker caps.

See also: Six-panel, Camp cap, Trucker cap

Flat embroidery

Standard machine embroidery stitched directly onto the cap without foam underlay. It handles fine detail and small text better than raised methods and works on structured and unstructured fronts, side panels, back arches and brims. Cost and appearance depend mainly on stitch count and number of colors.

See also: 3D puff, Stitch count, Digitizing

Foam front

A front panel made from a laminate of polyester fabric over foam, typical of classic trucker caps. It creates a tall, smooth face that holds its shape without buckram and gives a large, even area for printing or embroidery. It is usually combined with a mesh back.

See also: Trucker cap, Mesh back, Screen print

G

Gauge

In knitting, the number of needles per inch on the knitting machine bed. Lower gauges produce chunkier, heavier knits; higher gauges produce finer, smoother fabric. Gauge affects the look of a beanie and how much detail a knitted-in logo can show.

See also: Beanie, Rib knit, Acrylic

H

Hang tag

A printed card attached to a product, usually with a string or plastic fastener, carrying brand information, product details and often a barcode and price field. On caps it is often attached through the closure or an eyelet. Hang tags are part of retail and private label packaging.

See also: Woven label, Polybag, Carton marking

Heat transfer

A decoration method in which a design is printed or cut onto a carrier and applied to the cap with heat and pressure. It suits multicolor graphics, gradients and small details. Durability and hand feel depend on the transfer type and on correct application temperature and dwell time.

See also: Screen print, Sublimation, PVC patch

Hook-and-loop

A closure made of two fabric strips, one with small hooks and one with loops, that grip when pressed together. It allows fine size adjustment and is common on visors, performance caps and children's caps. The hook side can catch on knitwear and hair if exposed.

See also: Snapback, Strapback, Visor

I

Incoterms

Standard trade terms published by the International Chamber of Commerce that define where the seller hands over goods and who pays for transport, insurance and duties. Common examples are EXW (buyer collects), FOB (sea freight, seller loads on vessel), DAP (seller delivers, buyer clears import) and DDP (seller also pays import duties).

See also: Country of origin, Lead time, RFQ

L

Lab dip

A small swatch of fabric or yarn dyed to match a target color, usually a Pantone reference, and submitted for approval before bulk dyeing. Lab dips are judged under an agreed light source. Several attempts may be needed before the shade is approved.

See also: Pantone TPX/TCX, Strike-off, Proto sample

Laser perforation

Small holes cut into panels with a laser to provide ventilation, typically on performance and running caps made from synthetic fabrics. The laser seals the edges of the holes. Perforations can be arranged in patterns and placed where eyelets would otherwise sit.

See also: Eyelet, Moisture-wicking, Recycled polyester

Lead time

The time between a confirmed order and goods being ready to ship or delivered, depending on how it is defined. For caps it depends on quantity, material availability, decoration, sampling and approvals. Buyers should check whether a stated lead time includes sampling and transit.

See also: MOQ, RFQ, Pre-production sample (PPS)

Leather patch

A badge made from genuine or faux leather, decorated by debossing, embossing, laser engraving or printing, and sewn onto the cap. Leather patches give a premium, understated look on caps and beanies. Faux leather offers more consistent color and avoids animal-derived materials.

See also: Woven patch, Embroidered patch, PVC patch

M

Melton wool

A dense, heavily fulled wool or wool-blend fabric with a smooth, felt-like surface. Its weight and warmth make it a traditional choice for fitted and winter caps. It holds structure well and gives a clean base for embroidery and patches.

See also: Fitted, Merino, Structured

Merino

Wool from merino sheep, known for fine fibers that feel soft against the skin. It regulates temperature, resists odor and is used for premium beanies, alone or in blends. It needs gentler care than acrylic and usually costs more.

See also: Acrylic, Beanie, Melton wool

Mesh back

Rear and side panels made from open polyester or nylon mesh for ventilation, typical of trucker caps. Mesh is usually paired with a foam or fabric front and a snap closure. Mesh panels are not suitable for embroidery or printing.

See also: Trucker cap, Foam front, Snapback

Moisture-wicking

Describes fabrics or sweatbands that move sweat away from the skin to the outer surface, where it can evaporate. Usually achieved with synthetic fibers and specific fabric constructions or finishes. It is a key feature of performance, running and golf caps.

See also: Sweatband, Laser perforation, Recycled polyester

MOQ

Minimum order quantity. The smallest number of pieces a manufacturer will produce for an order. An MOQ may apply per order, per style or per color, and some components such as custom fabric, labels or trims can carry their own minimums. Always confirm how it applies on the quotation.

See also: RFQ, Lead time, Lab dip

P

Panel

One of the shaped fabric pieces sewn together to form a cap's crown. The number and arrangement of panels, for example five, six or seven, define the construction, seam positions and the surfaces available for decoration.

See also: Five-panel, Six-panel, Seven-panel

Pantone TPX/TCX

Pantone color references for textiles. TPX references are printed on paper and TCX references are dyed on cotton. Both describe how a color should appear on fabric and are the usual basis for lab dips and thread matching, while coated and uncoated print references are designed for print.

See also: Lab dip, Strike-off

Polybag

A plastic bag used to protect individual products or small packs during shipping and storage. Requirements may include size, thickness, recycled content, suffocation warning text and a barcode sticker. Structured caps need bags that do not crush the crown.

See also: Hang tag, Carton marking

Pom

A ball of yarn or faux fur attached to the top of a beanie. Yarn poms can match or contrast with the knit; faux fur poms are often detachable with a snap. Pom size and density are specified in the tech pack.

See also: Beanie, Cuff, Acrylic

Pre-curved brim

A brim whose insert is shaped to a curve during manufacture so the cap is ready to wear without bending. It is the usual choice on low and mid-profile baseball caps and dad caps. The degree of curve varies and is best specified with a reference.

See also: Brim, Sandwich brim, Crown profile

Pre-production sample (PPS)

A sample made with the final materials, trims, decoration and labels exactly as intended for bulk. Once approved, it is the reference for bulk production and for inspection. Any component that differs from bulk should be recorded in writing.

See also: Proto sample, Top of production (TOP) sample, Tech pack

Proto sample

The first physical version of a new style, made to check shape, proportions, profile and construction. Proto samples may use substitute materials or colors. Comments on the proto feed into the tech pack before the pre-production sample.

See also: Pre-production sample (PPS), Tech pack, Lab dip

PVC patch

A badge molded from soft PVC or similar rubber-like material, usually with raised and recessed areas in separate colors. It is durable, water-resistant and suited to bold, simple graphics. Custom PVC patches require a mold, which is a setup cost.

See also: Embroidered patch, Leather patch, Woven patch

R

Recycled polyester

Polyester fiber made from recycled material, commonly post-consumer plastic bottles or textile waste. It performs similarly to virgin polyester and is used in cap fabrics, mesh, sweatbands and beanie yarns. Buyers who need verified recycled content should state this in the RFQ.

See also: Moisture-wicking, RFQ, Acrylic

RFQ

Request for quotation. A document sent to a manufacturer asking for price and conditions for a defined product. For headwear it should state styles, quantities per colorway, materials, construction, decoration, labels, packaging, delivery destination and preferred Incoterm.

See also: MOQ, Tech pack, Incoterms

Rib knit

A knit structure of alternating raised and recessed columns, described by the number of each, such as 1x1 or 2x2. Rib is elastic, which helps beanies fit a range of head sizes, and it is the most common structure for cuffed beanies.

See also: Beanie, Gauge, Cuff

Ripstop

A woven fabric with thicker reinforcement yarns at regular intervals, forming a small grid. The grid limits how far a tear can spread. Ripstop nylon and polyester are used for lightweight camp caps, bucket hats and outdoor styles.

See also: Camp cap, Bucket hat, Canvas

Rope cap

A cap with a decorative cord running across the front of the crown just above the brim, often in a contrast color. Rope caps are typically structured and have a retro or golf character.

See also: Structured, Brim, Six-panel

S

Sandwich brim

A brim construction with a thin contrast layer between the top and underside fabrics, visible as a colored line along the brim edge. It is a styling detail often used on golf and fashion caps, and adds material and sewing steps.

See also: Brim, Undervisor, Pre-curved brim

Satin stitch

An embroidery stitch of closely placed parallel stitches that cross a narrow shape from side to side, producing a smooth, shiny surface. It is used for lettering, borders and narrow shapes, and over foam in 3D puff. Very wide satin columns become loose, so wide areas use fill stitch.

See also: Fill stitch (tatami), 3D puff, Digitizing

Screen print

A printing method that pushes ink through a fine mesh screen, one screen per color. It gives solid, opaque colors and suits flat panels such as foam fronts. Each color needs its own setup, so it is most economical with a limited palette.

See also: Heat transfer, Sublimation, Foam front

Seam taping

A narrow fabric tape sewn over the internal seams of a cap to cover raw edges and add strength. It can be plain or printed with a brand pattern or message, which makes it a subtle private label detail.

See also: Sweatband, Woven label, Panel

Seven-panel

A cap constructed from seven panels, giving different seam lines and a rounder crown than five- or six-panel styles. It is less common and is used mainly for fashion or specific streetwear looks.

See also: Six-panel, Five-panel, Panel

Six-panel

The most common cap construction: two front panels joined by a center seam, two side panels and two rear panels. Structured six-panel caps carry buckram behind the front panels. The center seam must be considered when placing a front logo.

See also: Five-panel, Seven-panel, Buckram

Snapback

A cap with an adjustable plastic strap at the back that closes with interlocking snaps. It covers a wide range of head sizes. The term is also used for the style of flat-brim, high-profile caps that traditionally use this closure.

See also: Strapback, Hook-and-loop, Fitted

Stitch count

The total number of stitches in an embroidery design, set during digitizing. It depends on size, filled area and stitch density, and it drives machine time and therefore cost. Typical cap front logos range from a few thousand to well over ten thousand stitches.

See also: Digitizing, Flat embroidery, Fill stitch (tatami)

Strapback

A cap with an adjustable fabric, leather or synthetic strap at the back, secured with a metal buckle, slide or clip. Strapbacks give a cleaner look than plastic snaps and are common on dad caps and camp caps.

See also: Snapback, Hook-and-loop, Dad cap

Stretch-fit band

An elastic band built into the sweatband or crown of a closed-back cap so it stretches to fit within a size range. Stretch-fit caps are usually offered in a small number of sizes, such as S/M and L/XL, instead of a full fitted size run.

See also: Fitted, Sweatband, Snapback

Strike-off

A test print or decoration run on the actual production fabric, submitted for approval before bulk. It confirms color, registration and how a print looks on the base material, and it is the print counterpart of a lab dip.

See also: Lab dip, Pantone TPX/TCX, Screen print

Structured

Describes a cap whose front panels are backed with buckram or fused interlining so the front stands upright and holds its shape. Structured caps give a crisp, defined look and a stable surface for decoration, particularly 3D puff and large patches.

See also: Unstructured, Buckram, Crown profile

Sublimation

A printing method in which dye is turned to gas with heat and absorbed into polyester fibers. The print becomes part of the fabric, with no surface feel, and allows full-color and all-over designs. It works only on polyester or high-polyester fabrics and on light base colors.

See also: Heat transfer, Screen print, Recycled polyester

Sweatband

The band sewn around the inside of a cap's opening, where it touches the forehead. It absorbs sweat, adds comfort and finishes the edge. Common materials include cotton, polyester, terry and moisture-wicking fabrics, and it is often a place for a brand label or print.

See also: Moisture-wicking, Seam taping, Stretch-fit band

T

Tech pack

A technical document that defines a product for manufacturing. For caps it includes drawings, construction, bill of materials, measurements, Pantone colors, artwork with placement, labels and packaging. It is approved before sampling and serves as the reference for sample review and inspection.

See also: Proto sample, Pre-production sample (PPS), RFQ

Toggle and drawcord

An adjustment system using a cord threaded through a channel and secured with a sliding toggle or cord lock. It is used on bucket hats, outdoor caps and some camp caps to tighten fit or as a chin cord.

See also: Bucket hat, Camp cap, Strapback

Top of production (TOP) sample

A sample taken from the first pieces of bulk production and checked against the approved pre-production sample. It confirms that bulk output matches the approved standard before the full run is completed.

See also: Pre-production sample (PPS), AQL, Proto sample

Trucker cap

A cap with a front of foam or fabric and a mesh back, usually closed with a plastic snap. Trucker caps come in five- and six-panel versions and in low to high profiles. The front gives a large surface for printing, patches or embroidery.

See also: Foam front, Mesh back, Five-panel

Twill

A woven fabric with a diagonal rib pattern created by offsetting the weft over and under the warp. Cotton twill is the most common cap fabric because it is durable, holds its shape and gives a smooth surface for embroidery.

See also: Brushed cotton, Canvas, Washed (garment-washed)

U

Undervisor

The underside of a cap's brim. It may match the main fabric or use a contrast color, traditionally green or gray, and can carry a print or small embroidery as a hidden branding detail.

See also: Brim, Sandwich brim

Unstructured

Describes a cap with no buckram behind the front panels. The crown relaxes and follows the shape of the head, giving a softer, lower look when worn. Unstructured caps suit flat embroidery and small patches better than large raised decoration.

See also: Structured, Dad cap, Buckram

V

Visor

A headwear style consisting of a brim attached to a band, with no crown. Visors are closed with hook-and-loop, elastic or a snap and are fitted with a sweatband. They are used for sports, events and hot conditions.

See also: Brim, Hook-and-loop, Sweatband

W

Washed (garment-washed)

A finishing process in which finished caps are washed, sometimes with enzymes or stones, to soften the fabric and give a faded, worn-in look. Results vary from piece to piece, so slight shade variation is part of the character of washed caps.

See also: Dad cap, Brushed cotton, Twill

Woven label

A label woven on a loom from fine yarns, with the design formed by the weave rather than printed. Woven labels are used inside caps for brand, size, care and origin information, and on beanie cuffs as an external logo.

See also: Woven patch, Hang tag, Seam taping

Woven patch

A patch woven from fine threads, like a woven label, then cut and finished at the edge. It holds finer detail and smaller text than an embroidered patch, with a flatter surface, and suits complex logos.
