Nylon Filament Market Shows Structural Divergence: Slice Cost Support vs. Terminal Demand Tug-of-War Intensifies

The nylon filament market in Shengze and Jiaxing this week (July 13-19) exhibited typical cost-driven price fluctuations, but the cautious stance of downstream weaving mills is weakening the transmission efficiency. Caprolactam prices inched up to 11,900-11,950 yuan/ton, and nylon 6 chips (regular spinning grade) followed suit to 12,400-12,500 yuan/ton, providing rigid support for nylon filament prices. However, profit distribution along the chain is uneven: upstream raw material gains are clear, while the price increases at the nylon filament stage are more structural, with overall transaction volume recovery far lagging price gains.

Variety Divergence: Differentiated Demand as a Bright Spot From the perspective of specific varieties, the market is not experiencing a broad-based rise but rather a clear structural divergence. The trading volume of 30D/1F bright nylon trilobal yarn increased significantly, directly corresponding to the growing demand from end-use apparel fabrics for flashy and linen-like textures. 160D nylon air-textured yarn saw acceptable trading, mainly due to the smooth movement of nylon taslon fabrics, which still have stable applications in outdoor and casual wear. More notably, demand for 40D/24F nylon FDY full dull yarn showed cyclical growth, with downstream applications in water-jet looms producing dull high-density nylon spinning fabrics, which are increasingly popular for down jacket linings and windbreakers due to their fine hand feel and good opacity.

In contrast, conventional varieties remained sluggish. Although the price of 70D/24F nylon-6 FDY ticked up to around 13,600 yuan/ton, demand was generally weak, reflecting the dull orders for standard nylon spinning fabrics. The 70D/24F full dull variety held at 15,200 yuan/ton but also underperformed. Sales of 20D/1F and 30D/1F semi-dull nylon monofilament rebounded slightly, but prices were stable. The interwoven fabric of nylon monofilament with rayon yarn emerged as one of the few recent sales highlights. In contrast, nylon-66 DTY, due to its narrow application scope, fell into a stalemate with prices but no buyers.

Upstream-Downstream Game: Cost Transmission Meets Order Bottleneck The core contradiction in the current market lies in the tug-of-war between rising upstream costs and insufficient downstream orders. The oscillating upward adjustment of caprolactam and nylon chips provides a clear cost-push logic for nylon filament prices. However, weaving mills show weak purchasing appetite for nylon filaments. This is because the overall transaction share of nylon interwoven fabrics is not large, and some fabric prices are undergoing volatile adjustments. This means that orders from end-use apparel brands and traders have not shown a substantial increase; weaving mills are more focused on digesting existing inventories or purchasing on demand, rather than actively restocking.

This cautious sentiment is reflected in the data: although prices moved up, trading volume only saw a 'small-scale recovery' rather than a trend-driven expansion. Profit margins along the chain are squeezed at the intermediate stage—nylon filament factories face rising raw material costs but cannot fully pass them downstream. In terms of purchasing rhythm, weaving mills tend to favor differentiated, high-value-added varieties while remaining on the sidelines for conventional commodities.

Trend Forecast: Prices to Rise Moderately Next Week, but Upside Limited Considering the upstream raw material trends and downstream purchasing sentiment, the nylon filament market is expected to maintain a steady-to-higher trajectory next week. Caprolactam and chip prices are unlikely to fall in the short term, and cost support remains solid. Differentiated varieties such as dull FDY and trilobal yarn, due to more balanced supply-demand dynamics, have stronger upward momentum. However, conventional varieties, constrained by weak terminal orders, have limited room for gains and may even face a situation of prices without buyers.

For market participants, the current phase requires more precise management of variety mix and inventory levels. The signal of upstream raw material price increases is clear, but whether it can be smoothly transmitted downstream depends on whether end-consumer demand can truly recover before the autumn peak season.

For Buyers - Focus on differentiated varieties (e.g., 40D full dull FDY, 30D bright trilobal yarn). These varieties, supported by more stable demand, have lower price correction risk and can warrant moderate stockpiling. - For conventional varieties like 70D FDY, purchase on demand to avoid inventory depreciation risk if terminal orders fall short of expectations. - Closely monitor caprolactam and chip price trends. If raw material prices soften, consider delaying purchases.

For Foreign Trade Companies - Actively recommend samples of popular fabrics like nylon taslon and dull high-density nylon spinning to overseas clients, taking advantage of the window before costs are fully passed through. - Step up promotion of nylon-rayon interwoven fabrics, a recent sales highlight, especially in European and Japanese-Korean markets. - For narrow-application varieties like nylon-66 DTY, control inventory to avoid capital tie-up.
