Abstract

Staple fibers produced by the existing oil are all water-repellent and cannot be applicable for the fields with hydrophilic requirement on the fibers. The invention provides polyester staple fiber hydrophilic spinning oil, which comprises the following components in percentage by weight: 70 to 80 percent of component A, i.e. polyether modified silicone oil; 10 to 20 percent of component B, i.e. isomeric alcohol polyoxyethylene ether phosphate; and 5 to 10 percent of component C, i.e. aliphatic amine polyether. An emulsion is prepared from the three components by adding water. The effective concentration of the emulsion is between 0.3 and 2.5 percent. A pH value of the emulsion is regulated to between 8.0 and 10.0. Not only the polyester staple fiber hydrophilic spinning oil of the invention is suitable for each process of the staple fiber spinning, but also the produced fibers have excellent hydrophilicity. The polyester staple fiber hydrophilic spinning oil can be directly used in the field of non-woven fabric weaving with hydrophilic requirement.

Description

technical field [0001] The invention relates to the field of synthetic fiber processing, in particular to a hydrophilic spinning oil for polyester staple fiber processing. Background technique [0002] As we all know, the technology used for conventional polyester staple fiber spinning oil is very mature, and a large number of materials and patent documents have carried out detailed reports on this. With the differentiation and functional development of fiber production, the output of short fibers used in the field of non-woven fabrics is increasing. Non-woven fabrics often have hydrophilic requirements in subsequent processing processes (such as spunlace, sizing, etc.). It is undoubtedly the most economical and convenient way to give fibers good hydrophilicity during the spinning process, which puts forward hydrophilic requirements for the oil agent used in the spinning process. [0003] In the prior art, staple fiber oils generally use straight-chain alkyl phosphate or st...
