In the week of July 20-26, the Jiangsu-Zhejiang nylon industrial chain recorded a notable data point: caprolactam market prices surged to 12,400-12,500 yuan/ton, a significant jump from prior levels; nylon 6 chips followed with prices rising to 12,900-13,000 yuan/ton. Upstream cost pressures are now transmitting to mid-stream filament segments, with nylon-6 FDY prices seeing slight upticks and weaving mills noticeably increasing restocking activity.
Cost Pass-Through and Variety Divergence
Looking at product performance, this rally is not broad-based but shows clear structural characteristics. In the first half of the week, mainstream 40D/12F and 70D/24F nylon-6 FDY saw volumes expand first, with domestic mainstream prices stabilizing around 15,500 yuan/ton and 14,400 yuan/ton respectively. Full matte 40D and 70D varieties also saw sales recover, reflecting a renewed preference for matte-finish fabrics at the end-market.
Notably, 100D nylon-6 FDY is gaining traction, primarily used in spray-bag fabrics for luggage. As outdoor travel and luggage export seasons approach, downstream restocking intentions are strengthening. Meanwhile, 160D nylon air-textured yarn trading remains steady, with transaction prices around 15,600 yuan/ton. Its interwoven product with 70D/24F nylon-6 FDY—taslan fabric—is gaining popularity, especially the honeycomb taslan variety which has become a market highlight.
On differentiated varieties, 30D/1F semi-dull nylon monofilament (first-grade) saw a slight demand uptick, used mainly in spray-window gauze and wedding fabrics. Although bright nylon FDY sales remain ordinary, its interwoven product with rayon—shiny nylon-cotton fabric—is emerging as a fabric highlight, offering new development directions for downstream apparel makers.
Chain Linkages and Market Outlook
The essence of this nylon filament price rise is the combined effect of cost push and restocking demand. Caprolactam, as the most upstream core raw material in the nylon chain, its price surge directly lifts nylon 6 chip costs, which then transmits to FDY. For weaving mills, raw material inflation means squeezed margins, but it also triggers a 'buy on rising prices' psychology, with some mills choosing to stock up early to lock in costs.
On the demand side, autumn/winter fabric export orders have increased slightly, while domestic sportswear sales are showing signs of activation. Although these order increments are modest in scale, combined with raw material price hike expectations, they are sufficient to support continued market volume expansion next week. Industry public data shows current nylon filament inventories in Shengze and Jiaxing are at medium-low levels. If orders continue to release, prices are likely to adjust upward.
However, it should be noted that this rally is primarily cost-driven. Whether end-consumption can effectively absorb it remains to be seen. If fabric price pass-through to garments is blocked, downstream procurement may slow. For weaving and trading firms, capturing variety structural differences is more critical than sheer inventory building.
