The core reason for using SILIT-SVP Lycra Protection is to solve common challenges faced by denim spandex elastic fabrics during production, processing, and use, such as elasticity loss, yarn slippage, breakage, and dimensional instability. Its benefits can be analyzed from four dimensions:production efficiency, product performance, environmental compliance, and cost control, as detailed below:

Ⅰ.Production Efficiency: Enhancing Processing Stability

 ● Reduced Fabric Waste

Prevention of Cutting Deformation:

Pre-treatment improves fabric dimensional stability, ensuring smooth edges and reducing waste from elastic shrinkage during cutting (especially for complex jean patterns).

Minimized Washing Damage:

Protects spandex during wet processes like desizing and enzyme washing, preventing direct erosion from washing aids (e.g., enzymes, acid/alkali solutions) and reducing post-wash brittleness or breakage.

● Simplified Process Steps

Multi-Functional Integration:

Solves "anti-slippage + anti-breakage + anti-wrinkle + elasticity protection" needs with a single agent, eliminating the need for additional anti-slip or sizing agents and shortening post-finishing processes.

Strong Compatibility:

Can be used in the same bath as anionic/non-ionic softeners and desizing agents, reducing equipment cleaning frequency and improving production efficiency.

 

II. Product Performance: Strengthening Core Competitiveness

●Sustained Elasticity Retention

 Through adual mechanism of fiber internal penetration fixation + surface film protection, it firmly secures spandex filaments and covered yarns during washing to prevent elasticity loss from slippage. Tests show that treated fabrics maintain20%-30% higher elastic recovery rate after 50 standard washing cycles, extending garment lifespan.

● Enhanced Structural Strength

Significant Anti-Slippage Effect: 

Reduces yarn sliding in high-friction/stretch areas (e.g., knee and hip parts of jeans), lowering risks of "white exposure" or holes, especially for high-elasticity fabrics (spandex content >5%).

Anti-Pilling:

Fixes fiber ends to inhibit tangling during washing or wear, improving fabric surface smoothness and meeting high-end denim’s "delicate texture" requirements.

●Optimized Dimensional Stability

Pre-treated fabrics show15%-20% lower shrinkage rate under hot-wet conditions, ideal for high-temperature processes (e.g., laser engraving, crimping), reducing "size deviation" complaints in finished products.
