SelvolTM Ultalux for Apparel

In apparel, Selvol Ultalux enhances colorfastness in fabrics. Its unique polymeric compound also delivers significant improvement in crock performance.

Preserving color fidelity has always been a challenge for fabric manufacturers. Ultimately, they need to affordably achieve true color without using hazardous chemicals and without the need for curing. Meanwhile, they need to make fabric that exceeds industry performance standards.

SEKISUI’s Selvol Ultalux helps them do exactly that.

Selvol Ultalux is a new finishing treatment for fabrics, and it boasts multiple benefits in one cost-effective product. It delivers a high crock rating and reduces the need for rework. Test results show it carries key benefits:

  • Improves fabric crock ratings of 0.5 or greater
  • Exceeds retailer requirements
  • Does not affect fabric color

As a result, designers can choose from a wider color palette and can be confident that the dye remains in the material. In turn, their consumers receive truer colors.

More Advantages: Selvol Ultalux for Apparel

Selvol Ultalux doesn’t stop with better crock ratings and colorfastness:

  • It can improve the wet and dry crockfastness of denim fabrics.
  • It has shown an affinity to other cotton and synthetic fabrics without affecting the hand.
  • It extends into manufacturing by minimizing processes traditionally needed to improve crock performance, which saves energy and water.
  • It eliminates the need for curing, which reduces overall production time.
  • It is compatible with typical softeners and products that manufacturers commonly use in the finishing process.

Furthermore, Selvol Ultalux is a nonhazardous, nonionic polymer, which provides a favorable worker safety profile.

Selvol Ultalux is suitable for use in multiple finishing process applications.
