• Spinning Technology: Fibers are divided into natural (cotton, linen, silk, wool) and chemical (polyester, nylon, viscose, spandex)
- Ring Spinning: The most widely‑used method. It produces compact yarn with few hairiness, yielding durable fabrics, commonly used for pure‑cotton items, shirts and bedding.
- Open‑end Spinning: Produces coarse yarn with abundant hairiness and good wear resistance, suitable for denim, canvas and heavy‑weight T‑shirts.
- Compact Spinning: An upgraded version of ring spinning. It generates yarn with extremely low hairiness for smooth‑surfaced fabrics, applied in high‑end shirts and knitwear.
- Siro Spinning: Two rovings are spun together. The resulting yarn boasts high tensile strength and anti‑pilling performance, largely used for woolen fabrics and knitted outerwear.
• Weaving Technology: Converts yarn into grey fabric, categorized into woven and knitted types
Woven (Shuttle Weaving): Warp and weft yarns interlace perpendicularly, creating flat and crisp fabric surfaces
- Plain Weave: Warp and weft yarns interlace one over, one under. Representatives: poplin, voile, canvas. Features: sturdy and wear‑resistant, relatively stiff hand feel, prone to wrinkling.
- Twill Weave: Features diagonal texture lines. Representatives: denim, khaki, serge. Features: substantial thickness, fine luster, softer than plain‑weave fabrics.
- Satin Weave: Long yarn floats are formed. Representatives: sateen, satin. Features: sleek and lustrous, soft, yet susceptible to snagging and fuzzing.
Knitting: Yarns interlock into loops, delivering great elasticity and softness
- Weft Knitting: Made by circular knitting machines and flat knitting machines. Includes T‑shirt jersey, sweatshirt terry fabric and rib fabric. High cross‑directional elasticity.
- Warp Knitting: Multiple yarns form loops simultaneously. Fabrics resist unravelling and have barely any stretch. Used for sport mesh fabric, underwear and sofa upholstery.
• Dyeing and Finishing Technology: Transforms grey fabric into colored finished fabric, determining fabric color and hand feel
Pretreatment
- Singeing: Burns off short surface fuzz to obtain smooth fabric and reduce pilling (mandatory process for shirts).
- Desizing: Removes weaving sizing agents to improve dye uptake.
- Scouring: Eliminates waxy substances and impurities from cotton.
- Bleaching: For white and light‑toned fabrics.
Dyeing Methods
- Piece Dyeing: Dyeing whole rolls of grey fabric, delivers uniform color, applied to most garment fabrics.
- Yarn Dyeing (Yarn‑dyed Weaving): Yarns are dyed prior to weaving. Representatives: denim, plaid fabric, striped fabric. Rich color layering yet higher costs.
- Garment Dyeing: Completed garments are dyed to achieve vintage and worn‑out effects.
Printing Technology
- Reactive Printing: Top choice for cotton and linen. Dyes penetrate fiber interiors with good color fastness and soft hand feel, for high‑end bedding and apparel.
- Pigment Printing: Pigments adhere to fabric surfaces at low cost. Thick prints feel stiff and tend to fade after washing.
- Digital Heat Transfer Printing: Mostly for chemical polyester fabrics, producing fine and vivid patterns; poorly applicable to cotton.
- Screen Printing / Discharge Printing: For T‑shirt printing. Discharge printing destroys base colors to reveal target patterns.
• Post‑finishing Technology: Imparts special functions to fabrics, playing a vital role
- Pre‑shrinking: Pre‑contracts fabrics to reduce garment shrinkage after washing, a must‑do process for cotton fabrics.
- Non‑iron / Wrinkle‑resistant Finishing: Resin treatment renders cotton wrinkle‑free; drawbacks include reduced fabric strength and potential formaldehyde risks.
- Brushing / Napping: Creates short surface fuzz for warmth, used for brushed bedding and flannel.
- Fleecing, Polar Fleece: Knitted fabrics are brushed into fleece for warm outerwear materials.
- Mercerization: Cotton fabric treated with strong alkali, gaining silky smoothness, luster and enhanced strength, for high‑end cotton shirts.
- Stone Washing: Washing with chemical auxiliaries to create hazy matte and soft texture, for vintage‑styled silk and denim.
- Water‑repellent, Oil‑repellent, Stain‑repellent Treatments: Functional coatings for outdoor jackets and workwear.
- Moisture‑absorbing and Quick‑drying Finish: Hydrophilic modification for chemical fibers, used for sportswear fabrics.
