Spandex Knit Fabric Manufacturers

What We Manufacture

Yitai is a knitting, dyeing and finishing operation. We knit the greige fabric, control the elastane ratio and stitch density, then dye and heat-set in our own finishing facility. That single-chain control is what keeps shrinkage, stretch recovery and shade consistent from the first roll to the last roll of a repeat order.

Our main constructions are single jersey, rib, interlock, pique and wrap knit. Spandex content typically runs from 15% to 27% depending on the application, and we adjust yarn count, gauge and finishing tension to hit the target hand feel and modulus.

Our Spandex Knit Fabric Range

Each collection below is a working family of constructions, not a single article. We build the specification inside the family to match the garment.

Weft Knit vs Warp Knit: Choosing the Right Structure

The knitting structure decides stretch direction, modulus and dimensional stability before any fibre choice is made. We recommend the structure first, then set the fibre blend and spandex ratio around it.

Fibre Selection: Nylon, Polyester and Blends

Fibre choice drives hand feel, moisture regain and abrasion life. We hold both nylon and polyester spandex programmes and can blend them where a garment needs nylon softness with polyester economics.

Critical Specifications We Build To

• Weight: 155–280 GSM across the current range, with tighter bands set per article.
• Width: 150–158 cm usable, confirmed against the cutting marker.
• Spandex content: 15%–27%, adjusted for compression target and recovery requirement.
• Stretch and recovery: verified by extension-and-set testing on the finished fabric.
• Shrinkage: controlled through heat setting on the finishing range and confirmed by wash testing.
• Colour: lab dip approval before bulk dyeing, with shade continuity across rolls.
• Surface: matt, full-dull, shiny, calendered, foil print and print programmes.

Quality Control and Acceptance

Our quality control system runs from yarn intake through knitting, dyeing, finishing and final inspection. GSM, stitch density, dimensional change, pilling, colourfastness and stretch recovery are checked against the agreed limits for each article, and we keep a control swatch from the approved sample for comparison on repeat orders.

For recycled programmes we operate under the Global Recycled Standard, covering processing, manufacturing, packaging, labelling, trading and distribution of products made with a minimum of 20% recycled material. Transaction certificates follow the material through the supply chain.

Customisation and Development Support

Our R&D group develops fabric from a garment brief, a physical sample or a technical drawing. Typical development work covers spandex ratio, knitting density, gauge, surface finish, print and colour, and we produce a counter sample for approval before bulk.

• Construction changes: single jersey, rib, interlock, pique, wrap knit.
• Fibre changes: nylon, polyester, cationic, recycled polyester, Sorona blends.
• Functional direction: opacity, compression, moisture management, chlorine resistance.
• Surface and colour: solid, matt, shiny, calendered, foil print, placement print.

Information We Use to Configure Your Solution

A usable proposal needs the working point, not just a fabric name. These are the inputs that let us set construction, fibre blend and finishing parameters with confidence.

Documentation, Packing and Serviceability

Bulk orders ship with the agreed test data, shade records and, where applicable, GRS transaction certificates. Rolls are packed to the roll length and wrapping method set in the order confirmation, and we retain approved samples and construction records so repeat orders can be matched against the original specification.

When a construction needs adjustment after the first production run, we work from the retained sample and the recorded finishing parameters rather than redeveloping from scratch.

Frequently Asked Questions

How does Yitai keep spandex knit fabric quality stable across repeat orders?

We knit, dye and finish in one chain and hold a control swatch from the approved sample. GSM, stitch density, shrinkage, stretch recovery and shade are checked against the agreed limits, and the heat-setting parameters recorded for the original run are reused on repeats.

Which construction suits high-compression gear?

Warp knit spandex is the usual choice for compression because of its higher modulus and locked loop structure. We adjust spandex ratio and knitting density to reach the required support level without losing recovery.

Can you develop a fabric from a garment sample or drawing?

Yes. Our R&D group works from physical samples, technical drawings or a written brief covering weight, width, stretch, opacity and colour. We produce a counter sample for approval before bulk production.

Do you supply recycled spandex knit fabric with certification?

We hold GRS certification covering products with a minimum of 20% recycled content, including processing, manufacturing, packaging, labelling and trading. Recycled polyester and Sorona blend constructions are available within our sustainability range.

What information do you need to quote a spandex knit fabric order?

Send the end garment, target GSM and width, fibre preference, stretch and opacity requirements, colour or print direction, care conditions, order quantity and packing method. With those inputs we can confirm construction, finishing route and a counter sample plan.

Which fabrics are available for swim and beachwear?

Our swim range covers nylon spandex and polyester spandex in full-dull, shiny, calendered, foil-print and floral print finishes, with chlorine-resistant elastane options for pool programmes. See the swimwear and beachwear collection for current articles.
