The post-process is a crucial step in the production of knitted wool sweaters. Despite the popularity of wool sweaters for their softness and comfort, some common problems such as shrinkage in the wash, pilling, lengthening, and color loss may occur during washing and daily use. In this article, we will delve into the causes of these problems as well as the solutions.
Knitted wool post-process
Shrinkage often occurs during the washing process of knitted wool sweaters. This is due to the fact that the fiber structure of wool shrinks when exposed to water. To minimize this, it is recommended to use cold water during washing, to avoid excessive agitation and vigorous rubbing, and to choose detergents specially formulated for wool.
Another common problem is pilling, a condition where small particles appear on the surface of the wool. This is usually caused by friction between the fibers. To minimize pilling, choose a gentle wash program and low spin speed while avoiding washing other garments with rough surfaces.
Sometimes wool sweaters may become longer than they were after washing. This may be due to the stretchy nature of wool fibers, which are softer and more malleable when wet. In this case, it is advisable to gently stretch the garment while drying and use a low-temperature iron after drying.
Finally, color loss is also one of the problems faced by some woolen sweaters. This can be due to poor quality or fixation of the dye. To avoid color loss, you can opt to use oxygen-free bleach and wash at low temperatures, while avoiding mixing with light-colored clothing.
Overall, the post-processing of knitted woolen sweaters is very important and it directly affects the quality and longevity of the garment. By adopting proper washing and maintenance methods, we can effectively reduce the occurrence of problems such as shrinkage, pilling, lengthening, and color loss in the wash, and keep wool sweaters beautiful and comfortable.
