What are the disadvantages of cotton yarn?

Cotton yarn, a staple in textiles, is loved for its natural breathability, but it has inherent drawbacks. Understanding these and optimizing accordingly is key to making cotton products more versatile - and Shengrun Textile offers practical solutions through technological innovation. 

Disadvantage: Cotton yarn absorbs 8%-10% moisture, and in humidity over 60%, it becomes heavy, breeds mold, and shortens lifespan.

Shengrun's Solution: We use "antibacterial and mildew-proof finishing", implanting eco-friendly antibacterial agents in yarn production to achieve Grade 0 mildew resistance (highest national standard). Our "3-proof cotton yarn" (water, oil, stain resistant) with nano-coating reduces water penetration, ideal for outdoor and bathroom use.

Disadvantage: Pure cotton fabrics have over 30% wrinkle rate after washing/folding, requiring frequent ironing.

Shengrun's Solution: "Liquid ammonia mercerization" tightens fiber structure, improving wrinkle resistance by 40%. High-end fabrics use "non-iron finishing", maintaining over 80% smoothness after 50 washes - perfect for business wear and hotel linens.

Disadvantage: Cotton has only 3%-5% elongation, with <20% rebound after stretching, causing loose cuffs or sagging.

Shengrun's Solution:Our "cotton-spandex blended yarn" (95% cotton + 5% spandex) retains cotton's texture while adding 15%-20% elasticity (spandex rebound >95%), ideal for sportswear and underwear needing fit.

Disadvantage: Pure cotton withstands only 5,000 rubs (national standard), with fibers breaking into pills easily.

Shengrun's Solution: "Compact spinning" reduces yarn fuzz, and "singeing" removes short fibers, boosting wear resistance by 60%. Our "cotton-polyester blend" (70% cotton + 30% polyester) uses polyester's strength to endure 15,000+ rubs, suitable for workwear and high-use home textiles.
