The nylon filament market is experiencing a tug-of-war between rising costs and weak demand. From August 31 to September 6, in Shengze and Jiaxing, upstream caprolactam prices rose again to 13,450-13,550 yuan/ton, while semi-dull nylon chip prices increased by about 400 yuan/ton from the previous week. However, downstream transactions did not expand correspondingly. This combination of rising raw materials and sluggish demand is forcing the entire supply chain to reprice.
Cost Pressures Intensify
Strong upstream prices are the core driver of this round of adjustments. Higher caprolactam quotes directly push up the cost center of nylon chips. A 400 yuan/ton increase in chip prices means spinning mills face greater cost absorption pressure. For producers whose main profit comes from processing fees, if raw material increases cannot be effectively passed downstream, margins will be further squeezed.
Notably, cost increases are not uniform. Semi-dull chip prices rose significantly, while price gaps for other specifications are widening. This structural divergence reflects different demand resilience across downstream sectors. For buyers, the key is to monitor the lag in cost transmission—typically, yarn prices adjust one to two weeks after chip prices rise.
Demand Divergence: Conventional Weak, Differentiated Active
From a product perspective, the market shows clear polarization. Conventional 70D/24F nylon-6 FDY saw reduced demand, although prices rose to 15,300-15,400 yuan/ton. In contrast, demand for 40D/24F nylon FDY fully dull increased, mainly for water-jet dull high-density nylon taffeta, with downstream consumption rising cyclically. Additionally, 30D/1F bright trilobal nylon yarn saw higher volumes, and 160D nylon air-textured yarn traded fairly well, indicating that differentiated products are gaining more orders.
This divergence reflects a shift in end-use consumption logic. Conventional nylon taffeta demand is flat, while dull and trilobal products, offering unique aesthetics or functionality, are finding growth in outdoor apparel and fashion fabrics. For weaving mills, adjusting product mix may hold more long-term value than simply squeezing procurement costs.
Market Outlook and Strategies
Currently, some large producers report slightly increased orders for nylon-blended woven fabrics, but overall annual demand is down from last year, mainly due to insufficient fabric orders, directly impacting nylon filament consumption. With upstream costs firm and rising, the market generally expects upward price adjustments next week. However, weak demand may limit gains, and price increases might not fully cover cost hikes.
For buyers, excessive waiting is not advisable. Cost-push increases are usually persistent; if raw materials continue to climb, yarn prices are likely to catch up. It is recommended to moderately increase stock of conventional specifications based on order cycles, while monitoring supply stability for differentiated items. For mills, optimizing product structure and reducing over-competition in conventional lines is key.
