Dyeing and finishing process of cotton spandex blended elastic cloth

Cotton spandex blended elastic cloth has been popular for less than 20 years since its inception. Its dyeing and finishing process is very popular and its process technology is also quite mature. A process for the production of cotton-ammonia blended stretch fabrics is also required. The setting of cotton spandex blended elastic fabric is different from that of polyester/cotton blended fabrics. After heat setting, the elasticity of spandex filaments can be reduced, and the weft elasticity and shrinkage (including distortion after washing) of cotton/spandex blended fabrics can be kept to the standard allowable. Within the scope to meet people's requirements for taking. As for the setting process is not a standard mode after the mercerization process or the mercerization process, most of them should be determined after the on-site wash plate according to the requirements of the customer on the width and elasticity of the finished product. There are even a few customers who do not limit the width of the finished product, which is called the natural width. It is only required to ensure that the elastic force is good. At this time, the process requirements can be met without using a shaping process.

Therefore, the dyeing and finishing process flow of cotton spandex blended elastic cloth is: turn cloth-stitching-singeing-recoiling-oxygen bleaching-setting-mercerizing-dyeing-finishing-finished product inspection

There are many factories that use cold-rolling technology, and the process of brewing and bleaching cotton-amino blended elastic fabrics is also a very good process route: turning cloth-stitching-singeing-cold-rolling-boiler-drifting-setting-silk - Dyeing - Finishing - Finished Product Inspection

Cold-rolled reactor technology is also the smallest damage to spandex, and now more and more manufacturers use this process as a pretreatment for cotton spandex blended elastic fabric. The same with pure cotton bleached cloth, cotton spandex blended elastic cloth processing bleached cloth also need to increase the bleaching process after mercerizing to ensure the whiteness of the semi-finished products.
