Abstract

The invention relates to a super-low-shrinkage water-repellent polyester industrial yarn and a preparation method thereof. The super-low-shrinkage water-repellent polyester industrial yarn is prepared by modified polyester spinning. By the use of the characteristic that at a certain temperature, the increasing amplitude of the free volume of an aminoadipic acid gylcol ester is much larger than that of a polyester macromolecular chain, the interface bonding performance between an organic fluorine water-repellent and oil-repellent finishing agent and polyester fiber is improved; meanwhile, since an amino group is positioned at the initiating end of an aminoadipic acid gylcol ester molecule, the hydrogen-bond interaction between the aminoadipic acid gylcol ester molecule and the polyester macromolecular chain is increased, and the migration is reduced to the most extent. The damage to the regularity and the crystallinity of a polyester structure is avoided, and the excellent performance of the polyester is remained; the wicking height of the super-low-shrinkage water-repellent polyester industrial yarn is smaller than or equal to 0.8 mm. The super-low-shrinkage water-repellent polyester industrial yarn can be used for water-repellent and oil-repellent places needed by industrial textiles.

Description

technical field

[0001] The invention belongs to the field of fiber technology, and relates to an ultra-low shrinkage water-repellent polyester industrial yarn and a preparation method thereof. Background technique

[0002] Since its appearance, polyethylene terephthalate (PET) fiber has developed rapidly because of its excellent performance, and its output has become the crown of synthetic fibers in the world. Polyester fiber has a series of excellent properties such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting, good heat resistance and light resistance, acid resistance, alkali resistance and corrosion resistance, and the fabric has the advantages of wrinkle resistance and good stiffness, so , Polyester fiber is widely used in clothing, industrial yarn and other fields.

[0003] With the improvement of people's living standards, people's requirements for textiles are getting higher and higher, and the functional finishing of tex...
