Fiber-treating agent, short polyester fiber made with the same, and nonwoven fabric

A fiber treatment agent, polyester technology, used in fiber treatment, fiber raw material treatment, synthetic cellulose/non-cellulose material pulp/paper, etc., can solve the problem of not fully imparting durable hydrophilicity and failing to achieve durable hydrophilicity. , Without considering the inhibition of scum and other issues, to achieve the effect of good carding through, inhibiting scum, and reducing the generation of scum

Problems solved by technology

Here, as the polyether polyester compound, for example, a compound obtained by polycondensing aromatic carboxylic acid, polyoxyalkylene glycol, and ethylene glycol is used, but there is still a problem that the durable affinity cannot be sufficiently imparted even with this treatment agent. Water-Based Disadvantages
[0008] In addition, in these known documents, only the property imparting to the non-woven fabric is mentioned, and no consideration is given to suppressing the generation of scum, which is a problem that occurs at the same time.
[0009] In this way, there is no oil composition that satisfies durable hydrophilicity, low foaming, and scum generation suppression at the same time.

Abstract

The present invention provides a fiber-treating agent comprising a component A, which is a polyester compound produced by carrying out a condensation polymerization of an alkylene glycol, a polyalkylene glycol, and at least one member selected from the group consisting of aromatic dicarboxylic acids, C 4-22 aliphatic dicarboxylic acids, and their ester-forming derivatives; a component B, which is a polyester compound produced by carrying out a condensation polymerization of a polyoxyalkylene monol, an alkylene glycol, and at least one member selected from the group consisting of aromatic dicarboxylic acids and their ester-forming derivatives; and a component C, which is a C 4-6 alkyl phosphate salt; and is characterized by components A, B, and C being blended in specific ratios. Also provided are polyester staple fibers treated with the treating agent, and a nonwoven fabric manufactured by processing the polyester staple fibers with high-pressure water jets.

Description

technical field [0001] The present invention relates to fiber treatment agents such as polyester staple fibers, polyester staple fibers, and nonwoven fabrics used in the production of nonwoven fabrics by high-pressure water flow, and particularly relates to inhibiting A fiber treatment agent with excellent static electricity generation and carding passability, low foaming when treated with high-pressure water, hard water resistance, and durable hydrophilicity, and polyester staple fibers and non-woven fabrics using this fiber treatment agent. Background technique [0002] Conventionally, a high-pressure water flow method has been used as a method for producing nonwoven fabrics such as towels and towels. In addition, an attempt has been made to produce non-woven fabrics using this method and using polyester staple fibers. However, the problem is that since polyester is a hydrophobic fiber, after the nonwoven fabric is produced by the high-pressure water flow method, the hydr...
