Import 420d Heavy Latex-Free Spandex Yarn — Buy in Bulk from Supplier in China

The 420D Heavy Latex-free Spandex Yarn from Jiangsu Shuangliang Spandex Co., Ltd is a 100% spandex yarn designed for high-elasticity applications, produced without latex to accommodate sensitive users. The 420 denier rating denotes a heavy yarn, providing superior strength and resilience compared to lighter deniers. This yarn is manufactured using a dry spinning technique, which enhances its smooth texture and consistency, making it ideal for industrial-grade production.

As a raw, bare yarn, it offers versatility for knitting and weaving processes, particularly in activewear, swimwear, and other elastic fabrics. The absence of latex ensures compatibility with users who have latex allergies, a critical factor for medical and performance apparel. Typical for 420D spandex, the yarn exhibits elongation properties of 500-700%, allowing for significant stretch and recovery. Industry standards for such yarns often include a tenacity of 0.6-0.8 cN/dtex and a modulus of 0.4-0.6 cN/dtex.

This yarn is widely used in the fashion industry for garments requiring high elasticity, such as leggings, sportswear, and form-fitting apparel. Its heavy denier makes it suitable for applications where durability and stretch retention are paramount. Importers should confirm the yarn’s compliance with textile standards such as Oeko-Tex 100 for harmful substances and ISO 204 for tensile properties.

Jiangsu Shuangliang Spandex Co., Ltd is located in the Shuangliang Binjiang Industrial Park, Ligang, Jiangyin, Jiangsu Province. The company’s position within a dedicated industrial park suggests access to advanced manufacturing facilities and a streamlined supply chain for spandex production. Jiangyin is a recognized hub for textile and synthetic fibre manufacturing in China.

The supplier is categorized as an imported-tier provider with a harbor trust tier, indicating a verified status for international trade. While the response rate and average response hours are currently zero, this may not reflect long-term performance. The company specializes in spandex yarns, with a focus on high-elasticity, latex-free products tailored for performance and medical applications.
