Standardized Laboratory Verification of Fabric Bending Hysteresis and Crimp Balance
Standardized testing of flexural hysteresis and crimp balance isolates structural yarn friction, securing dimensional stability and reducing garment scrap.
Cellulase Enzyme
Biofinishing Agent
Biopolishing agents used in textile finishing modify the surface characteristics of cellulosic fibers through controlled hydrolytic action. Applying cellulase enzyme to linen fabrics removes micro-fibrils from the yarn surface to produce a smoother texture. This biochemical treatment prevents future pilling and improves the handle of the woven fabric.
The reaction must be carefully terminated using high temperature or alkaline wash to prevent fiber damage.
Catalytic Action
Hydrolysis of the beta-1,4-glucosidic bonds in the cellulose molecules occurs selectively at the weakest points of the fiber extensions. Liquid formulations containing cellulase enzyme are introduced into the jet dyeing machine during the finishing stage. This reaction requires precise control of both acidity and temperature to maximize the removal of protruding fibers while preserving the structural integrity of the base linen cloth.
Action that is allowed to proceed unchecked will degrade the tensile strength of the warp and weft yarns, leading to fabric failures during subsequent sewing operations.
Strength Protection
Monitoring weight loss after enzymatic exposure represents the standard method for controlling the process. When fabric weight drops by more than five percent, the yarn structure is compromised. Using cellulase enzyme requires a balance between hairiness reduction and fabric strength.
