Problems solved by technology

However, such an operation adds a dyeing and finishing process and increases production costs. Many factories are unwilling to accept it.
Secondly, when concentrated sulfuric acid is used to open fibers, the system will release a lot of heat, and polyester fibers will shrink severely when exposed to high temperatures, which directly affects the success rate and production rate of products.
In addition, concentrated sulfuric acid fiber opening also has the disadvantages of high risk, high operation requirements for equipment and personnel, high environmental pollution, and difficult wastewater treatment.

Abstract

The invention discloses a polyester peach skin imitation finishing technology for a terylene and regenerated cellulose fiber interweaved fabric. For now, according to existing polyester peach skin imitation finishing for a regenerated cellulose terylene fabric, fiber opening treatment is firstly conducted generally, under the effect of strong acid such as concentrated sulfuric acid, macromolecularchain segments of regenerated cellulose fiber is broken into short molecular chains, and the purposes of increasing naps and improving softness, drapability and appearance are achieved; due to the operation, one dyeing and finishing process is added, and the production cost is increased. The polyester peach skin imitation finishing technology comprises the following steps that S1, fiber opening and dyeing of terylene components in one bath; S2, san washing; S3, reactive dyeing of regenerated cellulose components; S4, soaking and softening. According to the technology, the fiber opening step and the step of disperse dyeing of the terylene components are innovatively combined and completed in one bath in one step, the ideal fiber opening effect is achieved, the technology processes are shortened, and fiber opening in one bath cannot influence the colored light and color yield of disperse dyeing severely.

Description

technical field [0001] The invention relates to a fabric dyeing and finishing process, in particular to a jeanette-like finishing process for fabrics interwoven with polyester and regenerated cellulose fibers. Background technique [0002] As people pay more and more attention to environmental protection, and the depletion of oil resources and the reduction of arable land, the production of synthetic fibers and natural fibers is more restricted. The source of regenerated cellulose fiber is very rich, it is a renewable natural resource, it is sustainable, it can participate in the ecological cycle of nature, and it is environmentally friendly. As a textile fiber, regenerated cellulose fiber can not only meet people's requirements for clothing comfort, functionality and aesthetics, but also can obtain special hand-feeling fabrics through dyeing and finishing processes. [0003] Regenerated cellulose fibers (tencel, modal, viscose, etc.) almost all have a skin core layer. Tenc...
