Selection of predetermined dyeing process for nylon fiber dyeing uniformity
Selection of predetermined dyeing process for nylon fiber dyeing uniformity
To improve uniformity, strict requirements must be placed on the pre-treatment, dyeing, and heat setting processes of nylon fibers or fabrics. In actual production, it is possible to perform pre stretching and pre shaping before pre-processing, generally at 140-150 ℃ x30s, and with moderate overfeeding. Especially nylon filament fabrics are prone to wrinkling during high-temperature treatments such as dyeing, and once formed, it is difficult to eliminate, resulting in uneven dyeing and affecting the appearance. So, setting before dyeing can fix the shape of the fabric, stabilize the scale, and avoid problems throughout the entire processing.
