Taffeta

Taffeta is a plain-weave fabric woven tightly from fine, even yarns, giving a crisp, papery hand and a smooth, faintly lustrous face. In polyester it is a lining and curtain cloth — the tight weave gives it body, a dry handle, and a slight rustle, not the soft nap of a bedding fabric like peachskin.

What "T" means (170T, 190T, 210T, 290T)

The number before the T is a thread-count class: total threads per square inch counted both warp and weft. A higher T-count indicates a denser sett, tighter construction, and greater wind/water resistance. It is a construction specification rather than a single quality grade — a 210T lining and a 190T shell are engineered for different performance profiles.

Technical density and specification table

In waterjet weaving, polyester taffeta is categorized across mill grades by filament yarn denier, thread density, and finished fabric weight:

PA and PU coating options on taffeta

Uncoated greige or dyed taffeta has natural wind resistance due to its tight plain weave, but it is not waterproof. To achieve functional barrier performance for outerwear, umbrellas, and outdoor covers, specialized back coatings are applied:

• PA (Polyacrylate) Coating: A water-based or solvent-based polyacrylate emulsion spread across the fabric reverse. PA coating bonds yarn cross-points to prevent seam slippage, stiffens the hand for improved cutting and sewing, and imparts water resistance (typically 400mm–800mm hydrostatic head). It is an economical choice for umbrella cloth, rainwear linings, and light dust covers. In addition, PA silver coating incorporates reflective metallic pigments to block ultraviolet radiation (UPF 50+) and reflect solar heat for beach umbrellas, sunshades, and protective automobile covers.
• PU (Polyurethane) Coating: An elastomeric polyurethane film knife-coated or laminated onto the reverse face. PU provides superior tensile elasticity, a supple hand that does not turn brittle in freezing conditions, and high hydrostatic water resistance (typically 800mm–1,500mm+ water column). PU coatings can be formulated as clear, white (milky PU for improved opacity), or microporous breathable films, making 210T and 230T PU-coated taffeta the industry standard for outdoor tent flysheets, boat and vehicle covers, waterproof rain gear, and rugged equipment bags.

Taffeta vs pongee: yarn structure and hand

While both fabrics are plain-weave polyesters woven in high volumes on waterjet looms, the choice between them comes down to yarn morphology and tactile behavior:

• Yarn Structure: Taffeta is woven from FDY (Fully Drawn Yarn) in both warp and weft. FDY filaments are straight and smooth, giving taffeta its glassy surface, crisp paper-like firmness, and subtle luster. In contrast, pongee utilizes DTY (Draw Textured Yarn) in the weft (semi-elastic pongee) or in both directions (full-elastic pongee), introducing microscopic crimp and air space.
• Hand Feel and Sound: Taffeta has a firm, dry, and slippery touch that produces a distinctive rustle or "scroop" when crumpled or moved. Pongee is markedly softer, quieter, and drapes fluidly with almost zero fabric noise.
• Application Differences: Choose taffeta when your product demands structured stiffness, low surface friction, and easy sliding over other layers — such as garment sleeve linings, umbrella canopies, curtain backings, tote bag interlinings, and silver-coated solar covers. Choose pongee when the fabric rests against the skin or requires down-proof needle-hole self-recovery, such as down jacket shells, casual sportswear, and soft coat linings.

Why the weave gives the hand

Plain weave crosses warp and weft one over one, so the yarns lock hard and the surface stays flat. That is what produces taffeta's signature: crisp, smooth, slightly reflective, and stable. Calendering can add more sheen on top, but the tight plain structure is already the taffeta; the finish only polishes it.

Where polyester taffeta is used

• Curtain and drapery linings — body, opacity, and a smooth face behind the main cloth
• Bedding linings and inner bags — a tight, inexpensive base that does not fray easily
• Down-proof and pocketing — where a dense weave stops fill escaping
• Outdoor covers and awnings — 210T coated grades providing UV resistance and waterproof protection
• Decorative panels and banners — where the slight sheen and crisp rustle are wanted

What to put on the RFQ

• T-count (e.g. 190T or 210T) and yarn specification (e.g. FDY 63D/24F × 63D/24F)
• Weight in GSM, and width after finishing (see finished vs greige GSM)
• Face & finish — calendered/cire, plain dyed, antistatic, PA coated, PU coated, silver coated, or WR (water repellent)
• End use — lining, down-proof, umbrella, or outdoor cover, since that sets density tolerance and coating hydrostatic targets
