Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: because the material of the modified polyester is too dry and has a high oil content, the cutting of the modified polyester is relatively difficult, and it is difficult to effectively ensure the uniformity of the cut length of the modified polyester , and then it is easy to affect the soaring properties of the modified polyester fluff, so there is still room for improvement

Abstract

The invention relates to the technical field of preparation of electrostatic flocking fluff, in particular to a production process of modified polyester fiber electrostatic flocking fluff. The production process comprises the following steps: (1) performing pretreatment; (2) performing cutting; (3) performing fine removing of oil: adding water, an oil removal agent and sodium carbonate, and performing cleaning; (4) performing dyeing: adding a dye for dyeing, and performing washing; (5) performing electric treatment: adding a softening agent, aluminum sulfate, zirconium sulfate, ammonia chloride, sodium acetate and a humectant, and discharging liquid in a reaction container after a reaction; and (6) performing drying, wherein the added components are as follows in parts by mass: 100 parts of short fibers, 100-200 parts of water, 5-10 parts of the oil removal agent, 6-10 parts of sodium carbonate, 4-10 parts of softening agent, 3-6 parts of aluminum sulfate, 1-3 parts of zirconium sulfate, 1-2 parts of ammonia chloride, 0.5-1 part of sodium acetate and 0.1-0.3 part of humectant. The production process of the modified polyester fiber electrostatic flocking fluff has the effects of improving the flying property of the fluff and improving the flocking density of the fluff.

Description

technical field [0001] The invention relates to the technical field of preparation of electrostatic flocking fluff, in particular to a production process of modified polyester fiber electrostatic flocking fluff. Background technique [0002] At present, polyester generally refers to polyester fiber, which is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, and belongs to polymer compounds. However, polyester fiber has poor air permeability and is prone to pilling. Therefore, in modern technology, these shortcomings are usually gradually improved through chemical modification. [0003] The existing polyester chemical modification method generally introduces an asymmetric third monomer or polar group into the polyester macromolecular chain, thereby increasing the non-crystalline part of the polyester molecular structure, thereby improving the molecular activity of this part. performance. [0004] The a...
