Preparation method of polyester spinning oil

Abstract

The invention discloses a preparation method of a polyester spinning oil. An emulsifier in the invention can form an oil film on the surface of a chemical fiber, and a hydrophilic matrix in the oil film adsorbs moisture in air in order to form a continuous water film on the surface of the fiber, so accumulation of static charges, caused by friction, is reduced, apron winding, roller winding, cylinder winding and other undesirable phenomena are avoided, broken filaments and broken ends are reduced, and the quality of a fiber product is ensured.

Description

technical field

[0001] The invention relates to a preparation method of polyester spinning oil, belonging to the technical field of textile auxiliaries. Background technique

[0002] In my country, the trade name of PET polyester (polyethylene terephthalate) silk fabrics is called polyester. Polyester spinning generally adopts high-speed spinning-drawing and twisting process in China, that is, the two-step combination of pre-oriented yarn or partially oriented yarn and stretched textured yarn, referred to as POY-DTY process. In order to make polyester POY have a higher degree of orientation and crystallinity, the spinning speed is usually in the range of 3000-4600m / min. The faster the spinning speed, the higher the production efficiency. The high-speed spinning of polyester POY requires that the spinning oil used should have good smoothness, bunching and antistatic properties, so as to ensure good tow formation, proper embracing, and less broken ends of wool. In addition, ...
