Frequently Asked Questions

Q: What makes reactive dyed yarn superior to disperse dyeing for cotton?

Reactive dyes form covalent bonds with cellulose fibers, whereas disperse dyes are primarily for polyester. Reactive dyeing offers much higher breathability and wash-fastness for natural fibers.

Q: Is reactive dyed yarn suitable for industrial workwear?

Yes, it is ideal. With ISO 4-5 ratings for washing and perspiration fastness, it withstands the rigorous laundering cycles typical of industrial uniforms.

Q: How does "Siro spun" affect the final fabric quality?

Siro spinning produces a more compact and stronger yarn with fewer hairs, resulting in a smoother fabric surface and improved abrasion resistance.

Q: Does the dyeing process affect the moisture absorption of the yarn?

Unlike pigment dyes that coat the fiber, reactive dyes integrate molecularly, preserving fiber porosity and maintaining 15-20% better moisture absorption.

Q: What is the significance of high-temperature steam sizing?

Steam sizing prepares the yarn for weaving by improving its strength and smoothness, reducing breakage during the weaving process for higher efficiency.

Q: Can reactive dyed yarn achieve complex color effects?

Absolutely. Due to its deep shade penetration and clarity, it is the preferred choice for creating intricate ombré and heather effects in premium textiles.
