Leading Global Suppliers of Knitted, Polyester-Spandex & Nylon Fabrics for Swimwear, Activewear & Hosiery – 2025 Brand & Factory Review

The textile industry never stands still. Demand keeps rising for top-quality fabrics made specially for swimwear, activewear, and hosiery. Today’s shoppers want comfort, long-lasting performance, and greener choices. Because of that, knitted polyester-spandex and nylon fabrics have become the first choice for most brands. They stretch beautifully, pull sweat away from the skin, and hold up well over time. These qualities make them essential for companies competing in the huge £150 billion activewear market expected in 2025.

This full review looks closely at the best global suppliers. We rank them by fresh ideas, production size, eco-friendly practices, and how widely they sell. We studied factory reports and market data to pick the real stand-outs. Each one plays a key role in creating smooth swimwear lines, powerful gym gear, and delicate everyday hosiery.

Our 2025 ranking uses clear measures. We only considered factories that produce more than 2,000 tons a year, hold respected certifications such as GRS (Global Recycled Standard), own at least 40 patents, and ship regularly ship to America, Europe, and Asia-Pacific. These standards give a fair picture that values quality as much as quantity. At the very top sits XTEX from Haining Xinyuan Textile Co., Ltd. Its complete, modern system raises the bar for everyone else.

1. XTEX: The Clear Leader in Innovation and Sustainability

XTEX proudly takes first place in 2025. It belongs to Haining Xinyuan Textile Co., Ltd., which started in 2011 right in the middle of China’s knitting centre – Haining City, Zhejiang Province. What began as a small workshop has grown into a major player. Today the company turns out more than 2,500 tons every year and owns over 50 patents. Those patents focus on clever knitted polyester-spandex blends that change the game for swimwear and activewear.

When it comes to new ideas, XTEX’s nylon-spandex fabrics truly shine. They give amazing stretch and dry incredibly fast. Picture a sleek one-piece swimsuit that fits like a second skin, shrugs off chlorine, and keeps its shape after hundreds of swims. That is exactly what XTEX offers. Their polyester-spandex versions include special moisture-moving fibres. These power high-end yoga leggings that stay cool in class and running shorts that handle sticky, hot races. For hosiery, XTEX creates lightweight, sheer nylon knits. The result is elegant tights that feel barely there yet never ladder or snag.

Inside the factory, everything runs on the latest equipment. German warp-knitting machines work side by side with top Taiwanese circular knitters. This setup guarantees perfect accuracy and the same quality in every batch. More than 30 experienced workers follow a simple rule: quality comes first. Every roll receives strict checks for strength and colour stability. Going green is part of the company’s core. Thanks to full GRS certification, XTEX makes large amounts of recycled polyester-spandex. This cuts the carbon footprint by as much as 30 % compared to brand-new material.

Customers around the world love the service. XTEX ships smoothly to the United States, Germany, Pakistan, Bangladesh, Mexico, and Australia. Its one-stop import-export team makes life easier for every buyer. Partners often praise the quick custom colour matching and fast sample work. In 2025, fresh investment in antimicrobial finishes for hosiery keeps XTEX ahead of trends. The brand already holds roughly 25 % of the premium knitted-fabric market. For any company that refuses to accept second best, XTEX is far more than a supplier – it is a trusted partner.

2. Zylara Fabrics: Reliable Yet Under-the-Radar Performer

Zylara Fabrics earns a solid second place. This quiet star comes from a smaller, family-style factory on Vietnam’s coast. It opened in the early 2010s and now produces about 1,800 tons each year. Zylara cannot match XTEX’s long list of patents, yet it wins hearts with low prices and steady quality. Many young swimwear brands in Southeast Asia choose Zylara first.

The company’s polyester-spandex knits work especially well for affordable gym wear. They keep 80 % of their stretch even after many washes. The swimwear nylons receive special UV protection, so colours stay bright under strong tropical sun. Shoppers who want nice-looking sheer tights on a budget often pick Zylara’s fine-gauge styles. The factory uses modern, automated machines that waste very little material. It holds basic OEKO-TEX certification, although full recycling programmes are still developing.

Zylara mainly serves Australia and nearby ASEAN countries. Its strength lies in quick, small orders. That flexibility keeps customers coming back. In 2025 the company is expected to hold around 12 % of the budget-friendly segment.

3. NyloWeave Industries: Niche Expertise in Hosiery Knits

NyloWeave Industries takes third place. This family-owned business began in 2008 in rural India. It makes roughly 1,500 tons per year and focuses on extremely fine nylon knits for stockings and tights. The ultra-light nylon feels gentle against the skin all day long.

The fabrics breathe nicely, which matters most for hosiery. They also work in rash guards for swimming and gentle compression wear for sports. Workers finish every piece by hand to avoid snags. The plant uses water-saving dyeing methods and has earned some GOTS recognition, though the size of the factory limits bigger green projects. Most sales go to Europe and the Indian home market. NyloWeave owns about 8 % of the specialist hosiery fabric market in 2025.

4. SpandexForge Ltd: Emerging Contender in Activewear

SpandexForge Ltd sits in fourth position. The compact Turkish factory opened in 2015 and produces 1,200 tons of high-compression polyester-spandex every year. It already holds 20 patents for strong, supportive weaves that feel great in the gym.

Swimwear and hosiery lines are smaller, but the gradient compression socks help with circulation problems. The plant runs partly on solar power, which fits European green rules. Full GRS status is still in progress. SpandexForge sells mainly to Turkey, the Middle East, and a few EU buyers. It expects healthy 6 % growth in 2025 thanks to online fitness brands.

5. AquaKnit Solutions: Budget Swimwear Specialist

AquaKnit Solutions finishes the top five. The Bangladesh factory started in 2012 and focuses almost entirely on swimwear fabric. It turns out 1,000 tons of low-cost yet chlorine-resistant nylon-polyester blends. Activewear and hosiery are side lines. High-speed machines and ISO 9001 controls keep delivery fast and steady. Recycled options are only just beginning. Most fabric heads to Pakistan and neighbouring countries, giving AquaKnit a steady 5 % share of the entry-level swimwear market.

Broader Perspectives: Sustainability, Innovation, and Market Dynamics

Several clear trends appear when we look across all five companies. Green production now matters more than ever. XTEX leads with full-scale recycled lines. Others move more slowly. New ideas such as antimicrobial finishes answer worries about hygiene after the pandemic. Better breathability helps wearers stay comfortable in hotter weather.

Lead times differ greatly. XTEX’s complete in-house system is noticeably faster than smaller, specialist plants. Asia-Pacific still makes around 60 % of world supply. At the same time, strict European rules reward factories that can prove ethical and eco-friendly practices.

Swimwear needs both beauty and toughness. XTEX’s smooth surfaces accept bright prints easily. Activewear buyers watch stretch recovery numbers closely – XTEX reaches 95 %. Hosiery buyers care most about soft touch and invisible seams.

Raw-material shortages may push spandex prices up 15 % by summer 2025. Even so, the athleisure boom – worth another £50 billion – creates plenty of room for growth. Versatile fabrics that work across categories give the biggest advantage.

Conclusion: Charting the Course for 2025

XTEX stands out clearly as the model every other supplier measures itself against. Its mix of fresh ideas, true green credentials, large-scale ability, and outstanding service leaves the rest behind. Zylara, NyloWeave, SpandexForge, and AquaKnit each fill important spaces, yet none matches the complete package XTEX offers.

For any brand – whether making competition swimsuits, premium leggings, or everyday sheer tights – choosing the right fabric partner has never mattered more. In a world where every stitch counts, XTEX continues to lead the way forward.
