When prices on the quote sheet keep climbing while the transaction list quietly shrinks—that is the most straightforward picture of the nylon filament market in Shengze and Jiaxing in early September. Public quote platforms such as China Silk City Net show that since late August, nylon filament prices across specifications have been raised consecutively, but downstream purchasing has slowed markedly. The signal of price-volume divergence is now on the table. What the industry often calls 'quoted but not traded' is turning from a verbal warning into real pressure.
Event Background
Looking at specific quotes, this round of increases covers everything from monofilament to multifilament, from semi-dull to full-dull. For semi-dull nylon monofilament, 17D/1F first-grade is quoted at RMB 19,300 per ton, 20D/1F at RMB 19,100, and 30D/1F at RMB 18,100—each up by several hundred yuan from earlier levels. Differentiated products such as bright trilobal and fluorescent profiled yarns followed suit, with 30D/1F bright trilobal first-grade at RMB 18,100 and fluorescent yarn at RMB 16,300.
On the multifilament side, conventional specs like 70D/12F bright profiled are at RMB 14,100 per ton, and 110D/24F semi-dull at RMB 11,800, with more moderate gains. Nylon-6 FDY series show clear regional price gaps: 40D/12F from Hai'an is RMB 16,500, 50D/12F at RMB 16,000, 100D/36F from Changsha, Hunan at RMB 14,800, and 28D/10F from Fujian at RMB 17,300. Among ATY air-textured yarns, 160D semi-dull is at RMB 16,300, while full-dull from Shandong and Taiwan are at RMB 16,600 and RMB 16,700 respectively.
These numbers reveal two signals: fine-denier and functional products command stronger premiums, and regional price gaps reflect differences in cost structures and inventory pressure among producers. For buyers, this means the same specification may offer entirely different negotiation room depending on origin.
Industry Impact
The essence of price-volume divergence is cost-push inflation meeting a demand vacuum. Upstream raw materials like caprolactam are consolidating at high levels, providing a cost floor, but downstream weaving mills are adopting a hand-to-mouth approach, with stocking intentions falling to lows. This 'hot upstream, cold downstream' pattern means that price hikes by filament mills are more on paper, while actual discount space is quietly widening.
More noteworthy is the structural divergence. Monofilament products, used in high-end apparel fabrics and medical textiles with rigid demand, show stronger price resilience; conventional multifilaments, used in luggage and tents, are more affected by export orders and struggle to follow gains. This divergence implies that future nylon filament trends will not be a simple uniform rise or fall, but will follow independent paths based on downstream segment prosperity.
For the Shengze and Jiaxing industrial clusters, local weaving mills are both consumers of nylon filament and buffers in the price transmission chain. Rising raw material costs squeeze weaving profits, forcing some enterprises to shift toward higher value-added differentiated products, which in turn strengthens demand for specialty nylon filaments. It is foreseeable that profit distribution across the chain will reshuffle around product innovation.
Practical Advice
For Buyers - Avoid chasing highs in the short term; consider locking in prices in batches for forward contracts, leveraging regional price gaps (e.g., conventional FDY from Hunan or Shandong). - Monitor the sustainability of premiums for fine-denier monofilaments and functional profiled yarns; if downstream orders do not pick up simultaneously, delaying purchases may improve bargaining power.
For Foreign Trade Companies - Use 'short-term price lock plus floating clauses' in export quotes to hedge against risks from a potential raw material pullback. - Seize the current price window to prioritize orders for high-value differentiated products; for conventional items, carefully assess currency and freight fluctuations.
In summary, the nylon filament market is shifting from one-way rises to a high-level plateau phase. Transaction activity over the next two weeks will be a key indicator for direction. At this juncture, both mills and traders need less directional betting and more inventory and cash flow management.
