During the week of August 24-30, the nylon filament market in Shengze and Jiaxing experienced a notable co-rise in volume and price. The primary driver was cost-side pressure: caprolactam prices climbed to 13,100-13,200 yuan/ton, a weekly increase of 500-600 yuan, while nylon 6 chips rose to 13,500-13,600 yuan/ton. This upstream surge is transmitting rapidly down the value chain, and with downstream demand cooperating, the rally appears more sustainable.
Cost Pass-Through and Demand Resonance
Looking at product structure, 70D/24F nylon-6 FDY was the star performer, with volumes expanding and prices rising to 14,800-14,900 yuan/ton. This specification is mainly used in water-jet woven fabrics like nylon taffeta, nylon-polyester blends, and taslan, indicating that downstream weavers are stocking up for autumn/winter orders. In contrast, regular FDY specs such as 100D/36F, 140D/48F, and 210D/36F saw average demand, with 210D/36F only used for nylon-polyester oxford fabric. This divergence suggests the recovery is not broad-based but concentrated in specific specs and end-uses.
Notably, 160D nylon 6-ATY saw price increases in both full-dull and semi-dull variants, driven by demand for taslan and peach-skin fabrics. Strength in differentiated products often signals a shift toward quality and functionality rather than mere low-price volume. Nylon monofilament demand was moderate, with trading concentrated in 20D and 30D, but 30D/1F bright trilobal and round cross-section filaments were flat, indicating that the micro-denier segment has not yet awakened.
Industrial Impact: Dual Support from Export Orders and Domestic Demand
The backdrop to this rally is a slight increase in autumn/winter export orders and budding domestic demand for sportswear fabrics. For nylon filament producers in Shengze and Jiaxing, this means higher operating rates and reduced inventory pressure. However, upstream prices are showing signs of peaking; whether caprolactam can hold above 13,100 yuan/ton will determine the subsequent elasticity of nylon filament prices.
From a buyer's perspective, current price levels are near short-term highs, and the risk of chasing prices is accumulating. Historical experience shows that when upstream increases exceed 500 yuan/ton and downstream acceptance is limited, corrections often occur within 2-3 weeks. Therefore, weavers with rigid demand should purchase as needed and lock in prices in batches, while traders should closely monitor caprolactam plant operations and import arrivals.
Practical Recommendations
For Buyers - Lock in orders for hot specs like 70D/24F, but control order sizes to avoid high-priced inventory. - Watch for topping signals upstream; if caprolactam prices hold flat or decline for two consecutive weeks, postpone restocking. - Increase the proportion of differentiated products like ATY and dull yarns to meet rising quality requirements.
For Exporters - Use the current window of increasing autumn/winter orders to sign long-term contracts with filament suppliers and lock in costs. - Include raw material price linkage clauses in quotes to reduce profit erosion from caprolactam volatility. - Monitor exchange rates and shipping logistics to adjust FOB/CIF quotes promptly and avoid exchange losses.
In summary, the nylon value chain is in a resonance phase of cost push and demand recovery, but at high prices, market sentiment can easily become overly optimistic. It is advisable for all links in the chain to remain rational, aligning production and procurement with actual orders, and avoid blindly chasing price increases.
