As capacity expansion dividends fade, the nylon industry stands at a watershed. In August 2026, the annual meeting of the Nylon Branch of the China Chemical Fiber Industry Association, held in Shantou, Guangdong, signaled a core shift: prioritizing quality and efficiency while rejecting ineffective involution. This marks a sharp turn from scale competition to value reconstruction, and for buyers and factories, grasping this shift matters more than chasing price fluctuations.
Event Background
Industry data unveiled at the meeting painted a clear picture: the nylon 6 chain is in a phase of 'slowing capacity expansion but intensifying competition,' while nylon 66 faces challenges in stabilizing quality and supply. Reports from Liu Shiyang, full-time secretary of the Nylon Branch, and Zhuang Xiaohua, head of the synthetic fiber chain at Longzhong Information, collectively pointed to a transition from scale growth to quality improvement, with high-quality, differentiated, green, and intelligent development as the main themes.
Shantou, as the host city, showcased its transformation from 'fragmented and extensive' to 'full-chain aggregation,' as described by Weng Chuangjie, chairman of the Shantou Textile and Garment Industry Association. The momentum of nylon and nylon-spandex knitted fabric production bases reflects the industry's pursuit of cluster effects—a direct response to 'ineffective involution' by pooling resources rather than merely expanding capacity.
Industrial Impact
Technological breakthroughs provided the strongest confidence at the meeting. Professor Cai Zhengguo's team from Donghua University introduced an anionic ring-opening polymerization of caprolactam and direct melt spinning for nylon 6, reducing cyclic dimer residue to below 0.01wt% and compressing polymerization time to just over ten minutes. This directly addresses the pain points of traditional hydrolysis polymerization—long cycles and high oligomer residue—while achieving near-commercial spinning performance, opening doors for differentiated products.
Smart manufacturing and green energy are reshaping cost structures. Professor Hu Xudong from Zhejiang Sci-Tech University outlined a three-stage digital transformation path for the chemical fiber industry, with embodied robots highlighted as a core hotspot for building low-labor smart factories. Sien New Energy's smart integrated energy solutions target the high electricity and heat demands of nylon production, offering carbon management platforms and full-scenario intelligent control. These technologies elevate competition from mere capacity to systemic efficiency, raising capital and technical barriers for smaller enterprises.
Downstream application expansion is accelerating. Hangzhou Jiersi's halogen-free flame-retardant nylon chips, compatible with POY/FDY/BCF spinning processes, achieve an oxygen index of 30-32%, and blending with Lyocell solves melt-drip issues. Zhejiang Jincai's functional masterbatch matrix includes over 20 types, such as graphene, mint cooling, and white conductive, with antibacterial rates exceeding 99%. These innovations directly respond to market demands for functionality, safety, and comfort, offering buyers higher value-added options.
