During the week of July 20-26, the nylon filament markets in Shengze and Jiaxing experienced a clear cost-driven price rally. Caprolactam prices surged to 12,400-12,500 yuan/ton, a significant jump from previous levels, while nylon 6 chips followed suit, reaching 12,900-13,000 yuan/ton. This marks one of the steepest weekly increases in recent months, signaling that upstream cost pressures are accelerating downstream.
Market Transmission: Raw Materials Surge, Yarn Prices Edge Up
Compared to the aggressive rally in raw materials, nylon filament yarn prices showed only modest adjustments. Mainstream nylon-6 FDY specifications such as 40D/12F and 70D/24F were quoted at around 15,500 yuan/ton and 14,400 yuan/ton (domestic), respectively, with only slight increases. This 'big raw material rise, small yarn rise' pattern reflects downstream weaving mills' cautious restocking approach—they are not unwilling to follow price hikes, but rather waiting for final order confirmation to avoid inventory risks.
However, trading volumes for these core specs picked up notably in the first half of the week, suggesting some mills are already building stocks for upcoming orders. Demand for full-dull 40D and 70D nylon FDY also rebounded, linked to rising seasonal demand for matte, anti-transparent fabrics in autumn/winter outdoor apparel.
Product Differentiation: Specialty Items Shine
Market performance varied significantly across categories. 100D nylon-6 FDY emerged as a top mover, primarily used in spray-loom bag fabrics, reflecting a recovery in luggage export orders. 160D nylon air-textured yarn maintained stable trading volumes at around 15,600 yuan/ton, often interwoven with 70D/24F nylon FDY to produce taslon fabrics, with honeycomb taslon becoming a standout product in the autumn/winter segment.
In specialty yarns, demand for 30D/1F semi-dull nylon monofilament (first-grade) rose modestly, used in spray-loom window gauze and wedding dress fabrics. This uptick in fine-denier products often correlates with recovery in wedding and home decoration end-markets. Notably, bright nylon FDY sales remain sluggish, but flash nylon-cotton fabrics interwoven with rayon are emerging as a new style highlight.
Demand Side: Export Orders and Domestic Demand Converge
On the demand side, autumn/winter fabric export orders have increased recently, while domestic sportswear and outdoor apparel procurement is also gaining momentum. This timing overlaps with the raw material price rally, putting weaving mills in a dilemma—whether to restock at higher prices or wait for order confirmation.
For buyers, current yarn prices have not fully absorbed upstream cost increases. If caprolactam and chip prices continue to rise, a catch-up rally in nylon filament prices is almost inevitable. Industry data shows caprolactam has accumulated gains of over 15% year-to-date, while nylon FDY prices have risen only in single digits, leaving significant margin compression.
Practical Recommendations
For Buyers - Consider forward procurement of core nylon FDY specs like 40D and 70D to lock in current prices and hedge against further increases. - Monitor inventory levels of differentiated products like 100D and 160D, which have tighter supply elasticity and may face shortages during peak season. - Negotiate short-term price lock agreements with raw material suppliers to keep cost fluctuations within predictable ranges.
For Exporters - Include raw material price adjustment clauses in autumn/winter fabric quotations to account for ongoing caprolactam increases. - Prioritize differentiated products such as honeycomb taslon and flash nylon-cotton fabrics for export, as their higher value-added nature makes clients less price-sensitive. - Take advantage of current RMB exchange rate windows to settle or hedge currency exposure early.
Overall, this nylon filament price rally is not an isolated event but a systemic adjustment driven by strong upstream raw material costs. The transmission chain from caprolactam to chips to yarn is clear and irreversible. For all links in the chain, the core strategy is no longer 'whether to raise prices,' but 'how much, how fast, and who bears the cost.'
