Nylon Chain Price Hikes: Structural Divergence in Shengze and Jiaxing Markets

A rapid rally in raw material costs is sending ripples through the nylon filament markets in Shengze and Jiaxing. During the week of August 24-30, caprolactam prices climbed to 13,100-13,200 yuan/ton, up 500-600 yuan/ton weekly, while nylon 6 chips followed to 13,500-13,600 yuan/ton. This cost push lifted nylon filament prices overall, yet a notable divergence emerged among specifications—not all products share equally in the gains.

Cost Pass-Through and Product Divergence

Among specific items, 70D/24F nylon-6 FDY stood out with both higher volumes and prices, reaching 14,800-14,900 yuan/ton. This spec is mainly used in water-jet woven nylon taffeta, nylon-polyester blends, and taslan for domestic demand, and its active trading reflects solid downstream orders. In contrast, regular FDY specs like 100D/36F, 140D/48F, and 210D/36F saw only moderate volumes, despite 210D/36F being used in polyester-nylon oxford fabric.

Notably, 160D nylon 6-ATY saw price increases in both full-dull and semi-dull variants, driven by demand for nylon taslan and peach skin fabric. Meanwhile, nylon monofilament (20D, 30D) demand remained flat, and 30D/1F bright trilobal and round cross-section yarns saw quiet sales. The 70D/24F full-dull FDY performed well, used for dull nylon taffeta and dull taslan, with prices also edging up.

This divergence reveals a structural shift in downstream demand: improvements are concentrated in specific specs tied to sportswear and early autumn/winter orders, not a broad recovery. For buyers, this means not all nylon yarns have equal pricing power, and inventory strategies must be spec-specific.

Chain Dynamics and Price Outlook

From a value-chain perspective, the rally originates upstream—caprolactam and chip prices rose in tandem, directly raising spinning costs. Under cost pressure, yarn price hikes are inevitable, but whether they fully cover cost increases depends on supply-demand dynamics for each spec. Currently, hot sellers like 70D/24F have kept pace with raw material gains, while regular specs lag.

A note of caution: raw material prices show signs of peaking. Although upstream support remains, if downstream demand fails to sustain, the cost pass-through may lose steam. Foreign trade orders for autumn/winter are only “slightly increasing,” and domestic sportswear demand is “stirring” but not robust. Thus, nylon yarn prices are likely to stay firm in the short term, but upside may be limited, possibly entering a high-level consolidation phase.

For weaving mills, rising input costs are squeezing margins. With limited order growth, mills cannot fully pass on costs, and some may cut operating rates or adjust product mixes. Traders face a dilemma: inventory gains versus the risk of a price correction.

Outlook and Recommendations

Overall, the nylon filament market will likely maintain a “cost-supported, moderate demand” pattern. Trading volumes may continue to expand, with prices trending firm-to-higher, but close monitoring of raw material movements and actual order placements is essential. Should raw materials peak and reverse, yarn prices could soften, making inventory management critical.

For Buyers - For hot specs like 70D/24F, consider forward contracting but avoid overstocking to hedge against pullbacks. - For regular specs (e.g., 210D/36F), adopt a need-based purchasing strategy and leverage supplier competition to lower costs. - Track caprolactam and chip prices as key indicators for purchasing timing.

For Exporters - Include raw-material price adjustment clauses in autumn/winter quotations to mitigate cost volatility. - Prioritize differentiated, high-value-added products (e.g., dull, ATY) to reduce competition in commodity grades. - Monitor exchange rates and shipping costs to protect export margins as domestic prices rise.
