Continuous Cleansing
Chemical treatment of woven fabrics in a flat, unwrinkled state removes natural impurities without introducing permanent creases. Performing open-width scouring on linen fabrics involves passing the textile through a series of chemical baths and spray zones under constant width-wise tension. This method prevents the formation of running creases that often occurs during rope-form processing.
Processing Stage
Woven linen contains large quantities of natural waxes and pectins that must be removed before dyeing or finishing. During this treatment, hot alkaline solutions break down these non-cellulosic impurities, allowing them to be washed away from the fiber surfaces. This step must be carefully controlled to avoid degrading the core cellulose, which would reduce the tensile strength of the finished linen fabric.
Fabric Appearance
Maintaining the fabric in an open width ensures that the chemical treatment is applied uniformly across the entire face of the textile. Uniform scouring ensures that subsequent dye uptake is completely even, preventing the patchiness and streakiness that can arise from inconsistent treatment. Furthermore, the absence of rope marks and crease lines reduces the need for mechanical straightening, which helps preserve the natural texture and hand of the woven linen for high-end fashion applications.
It also minimizes fabric shrinkage during the subsequent drying and heat-setting phases, yielding a more stable finished product.
