Problems solved by technology

[0005] Polyester fiber is a synthetic fiber, the biggest advantage is good wrinkle resistance and shape retention, but the disadvantages are poor air permeability, dyeability, easy pilling and fluffing, and static electricity caused by dust absorption, etc., and the use of spinning oil can just give polyester Certain antistatic properties of fibers
However, the general spinning oil will have the problem of poor coating on the fiber during use, which will cause greater friction of the fiber, resulting in defects such as bifurcation and broken ends of the produced yarn.
In response to this problem, the present invention has developed a spinning oil for processing recycled polyester fibers, which can significantly reduce the generation of static electricity, thereby avoiding the fiber quality being affected by the spinning process.

Abstract

The invention discloses spinning oil for processing regenerated polyester fiber, and relates to the technical field of regenerated polyester fiber processing. The spinning oil is formed by mixing, by weight, 1-10% of glycerin, 1-10% of polyglutamic acid / polyethylene glycol monomethyl ether, 1-10% of an antistatic agent, 1-10% of a custer agent, 1-10% of fire retardant and the balance distilled water. By means of the spinning oil, the smoothness and softness of the polyester fiber can be remarkably improved, the kinetic friction coefficient between the fiber and metal is reduced, the static friction coefficient between the fiber is increased, and static electricity is reduced.

Description

[0001] Technical field: [0002] The invention relates to the technical field of regenerated polyester fiber processing, in particular to a spinning oil for regenerated polyester fiber processing. [0003] Background technique: [0004] Spinning oil is a liquid substance added to the spinning solution before chemical fibers or synthetic fibers are spun into fibers. Stretching, combing and other processes can be carried out smoothly, and at the same time, the formed fibers can be smooth, soft and antistatic. [0005] Polyester fiber is a synthetic fiber, the biggest advantage is good wrinkle resistance and shape retention, but the disadvantages are poor air permeability, dyeability, easy pilling and fluffing, and static electricity caused by dust absorption, etc., and the use of spinning oil can just give polyester The fiber has certain antistatic properties. However, the general spinning oil will have the problem of poor coating on the fiber during use, which will cause great...
