Yarn Expo Shanghai 2025: Special Nylon 2# Replaces Hank-Dyed Yarn

Yarn Expo Shanghai 2025: Special Nylon 2# Replaces Hank-Dyed Yarn

The spring edition of the China International Trade Fair for Fibres and Yarns opened at the National Exhibition and Convention Center in Shanghai from 11 to 13 March 2025, bringing together spinners, knitters, weavers and trading houses across three halls. Zhejiang Huayou Color Spinning Technology Co., Ltd. exhibited the full colour card, with the stand organised around a single proposition: that a buyer no longer needs to choose between the hand of hank-dyed yarn and the speed of stock supply.

The problem Special Nylon 2# was built for

Hank dyeing produces a soft, full hand that sock manufacturers have relied on for decades. It also carries a long lead time, a minimum batch per colour, and a batch-to-batch variation that must be managed at the knitting machine. For a mill running seasonal colour programmes against retail delivery dates, the trade-off has become harder to justify.

Special Nylon 2# is a two-ply nylon yarn at 70D/24F/2, engineered as a direct replacement for hank-dyed yarn and held in 365+ colours from stock. It sits alongside the company's dope dyed DTY range — 300+ colours at 70D/24F — and the dyed yarn range, 1,000+ colours at 70D/24F/2 plus 335+ colours at 40D/2. Taken together, more than 1,000 colours of nylon yarn are available without a production slot.

The proposition is narrow and practical: the same construction, the same count, the same downstream process, with the colour taken from a card rather than from a dye lot.

Visitors at the stand

The Shanghai fair draws a mixed audience, and the stand reflected it. Sock manufacturers from Zhejiang, Jiangsu and Guangdong compared Special Nylon 2# against their existing hank-dyed supply, most of them holding a knitted sample rather than a shade number. Weavers sourcing for jacquard and narrow fabric asked about 70D/68F and 100D/48F, where filament count governs the surface of the cloth. Trading houses servicing markets in Southeast Asia and the Middle East requested the specification sheet and the export packing details together with the price.

The most frequent question was not about price. It was about whether the substitution changes the finished article — whether a sock knitted from Special Nylon 2# matches one knitted from hank-dyed yarn in hand, thickness and wash behaviour. The answer given at the stand was that the construction is matched and the yarn is supplied for trial knitting before any volume commitment, with the customer's own sock used as the reference for colour approval.

Orders and trials placed

A sock manufacturer in Zhejiang placed a trial order of 300 kilograms of Special Nylon 2# across six colours, with the intention of converting one autumn programme from hank-dyed supply if the knitting trial is accepted. A weaving mill in Jiangsu took samples of 70D/68F dope dyed DTY in four colours for a jacquard development, and a trading company serving the Middle East requested a quotation for 70D/24F/2 in twelve shades against a repeat programme.

What the fair confirmed

Three days in Shanghai made the direction of the market clear. Buyers are consolidating suppliers — fewer vendors, wider colour coverage, shorter lead times. A supplier who can hold 1,000 colours in stock and ship a 300-kilogram lot in two days answers that consolidation directly, and the conversation moves quickly from price per kilogram to the size of the first trial.

Next edition

The company will exhibit at the autumn edition in Shanghai and again in 2026, with an expanded Special Nylon 2# colour range. Buyers wishing to evaluate the substitution are invited to request a colour card and a trial quantity, or to arrange a factory visit in Zhuji, Zhejiang.
