The knitted fabric is crocheted by the coils. After the yarn is subjected to pre-treatment, dyeing, water washing and the like, the coil is radially stretched and the shrinkage dimension is shortened. If it is not through the flat blanket shrinking machine, but directly by the loose dryer, although some deformation is restored, some internal stress remains in the fabric. When the knitted fabric is wetted again, the length of the fibers and the yarn (line) is shortened due to the relaxation in the inner portion, and the fabric is shrunk.
The flat blanket shrinking machine has unique requirements and has become an energy-saving and environmentally-friendly finishing equipment. At the same time, it also solves the old-fashioned blanket fixing process, and it is difficult to achieve the effective purpose of pre-shrinking. It can only be used as a stereotype processing and damping type. The pre-shrinking machine has many problems such as softness and fullness, and it is difficult to meet the requirements of high-end underwear, thereby improving the dimensional stability of the knitted fabric, the flatness of the cloth surface, and the low residual shrinkage rate.
After the processing of the flat-width blanket shrinking machine, the product quality is stable, the product grade and the product rate are improved, and the enterprise has increased the market competitiveness, making it the best ideal finishing equipment in the knitting industry. Pre-shrinking finishing of cotton, chemical fiber, blended fabrics and knitted fabrics. The fabric finished by this machine is stable in size. The cloth surface is flat and the residual shrinkage rate is low.
