The nylon filament markets in the Shengze and Jiaxing textile clusters presented a clear picture of cost-driven pressure and demand divergence in the week from June 29 to July 5. Raw material caprolactam prices edged up to the 10,950-11,000 yuan/ton range, with nylon 6 chips following suit to 11,400-11,500 yuan/ton, both showing slight week-on-week increases. However, this cost-side support did not translate into synchronized downstream acceptance across all product lines—different specifications and applications are experiencing markedly different market conditions.
Raw Material Cost Pass-Through and Structural Demand Divergence
Examining the hot and cold spots in trading, the current market is not a broad rally. The 15D/34F nylon DTY continued to sell briskly, directly linked to its rigid demand in lightweight, high-elasticity fabrics. End-of-June restocking by downstream weaving mills was concentrated in this category. In contrast, demand for 70D/24F nylon-6 FDY was mediocre, with prices stable at around 13,800 yuan/ton. The underlying cause is the slowing sales of nylon-polyester blended fabrics, which has sapped purchasing power for this specification.
More noteworthy is the divergence within the full dull series. Demand for 40D/24F full dull FDY has seen a cyclical uptick, driven by orders for dull high-density nylon spun from water-jet looms. Meanwhile, the 70D/24F nylon 6-FDY full dull variant performed poorly, with prices at 15,300-15,500 yuan/ton. Its market share is being eroded by polyester FDY full dull products, which are widely used to produce full dull polyester taffeta, creating a direct substitution effect.
Among niche products, 160D nylon air-textured yarn maintained stable sales channels, while 30D/1F bright nylon trilobal profiled yarn saw limited trading volume, indicating a narrow market capacity for such differentiated items. Nylon 66 DTY, due to its restricted application scope, has fallen into a state of price without buyers.
The Game Between Upstream Price Support and Downstream Inventory Digestion
The central tension in the current market lies in the rhythm mismatch between the volatile upward movement of upstream raw materials and the downstream weaving mills' efforts to digest previously built inventories. Industry data shows that total demand for nylon blended fabrics this year has indeed expanded compared to the same period last year, with orders being placed sequentially. However, downstream mills are currently more inclined to work through their existing stockpiles rather than chase higher-priced purchases. This means the cost pressure from the raw material side has not yet been fully and smoothly transmitted to the final fabric stage.
For nylon filament producers, rising chip prices are squeezing profit margins. However, rash price increases risk losing orders, especially for conventional high-volume items like 70D, where price elasticity is low and room for hikes is limited. Fine denier DTY, due to its relatively tight supply-demand balance, gives suppliers stronger bargaining power.
Practical Recommendations
For Purchasers - For popular items like 15D DTY, maintain reasonable inventory levels to avoid stock-outs due to potential short-term supply tightness. - For 70D FDY and full dull series, adopt a phased procurement strategy. Lock in some volume at current stable prices while closely monitoring price movements of polyester substitutes. - For nylon 66 products, postpone purchases unless absolutely necessary, waiting for improved market liquidity.
For Foreign Trade Enterprises - Factor in rising raw material costs when quoting, especially for orders involving fine denier DTY and dull high-density nylon spun. Shorten the validity period of quotations. - Monitor the recovery pace of overseas orders for nylon-polyester blended fabrics, as this will directly impact future demand for 70D FDY. - For full dull polyester taffeta products, evaluate the cost differences between nylon and polyester solutions to offer clients more cost-effective alternatives.
In summary, the nylon filament market is likely to enter a phase of moderate adjustment in the coming week. Upstream cost support remains, but the pace of downstream demand release will be the key variable determining price direction. Enterprises within the industrial clusters need to find a new balance between cost control and market expansion.
