Problems solved by technology

[0011] However, triocane (Patent Documents 1 and 2) is fat-soluble and is suitable for suppressing moisture volatilization, but it is difficult to retain moisture, and the moisturizing effect is not sufficient, and fiber treatment agents using silk protein (Patent Documents 3 and 4), Does not meet the skin's wearing feeling or the moisturizing requirements of the cutin
[0012] In addition, γ-linolenic acid (Patent Document 5) is an unsaturated fatty acid, which not only lacks stability when treating clothes, but also has insufficient moisture retention.
[0013] Moreover, even the fiber softening agent made of polyglycerin fatty acid ester disclosed in Patent Document 6 cannot obtain sufficient moisture retention.
This is considered to be due to the fact that the polyglycerin fatty acid esters described in Examples and the like are monovalent fatty acid esters, and a liquid crystal structure cannot be obtained on the surface of the fiber, and a sufficient water retention structure cannot be formed.

Embodiment 1～6 and comparative example 1～8

[0054] Adjust the fiber treatment agent according to the formula in Table 1, and use the exhaust dyeing method [equipment: newmatchmangle (ニユ一マツチチチングル) IPM-1 type: manufactured by Tsujii Dyeing Machinery Co., Ltd., sensitivity (pick-up) 60%, drying at 120 ° C × 2 minutes], cotton and polyester fabrics were treated as test fabrics. In addition, untreated cloth was used as a control. A moisture absorption rate test and a moisture permeability test were performed on these test cloths.

[0055] In addition, the adhesion amount of the fiber treatment agent on the fabric was 1.8% in Example 1, 1.5% in Example 2, 1.5% in Example 3, 1.8% in Example 4, 1.5% in Example 5, and 1.5% in Example 6. 1.5%, Comparative Examples 1-3 were 1.8%, Comparative Example 4 was 0.6%, Comparative Examples 5-7 were 1.8%, and Comparative Example 8 was 0.6%.

[0056] According to the results shown in Table 2, for the moisture absorption test, high moisture absorption was shown in Examples 2 and 5, and esp...

Embodiment 5、 comparative example 5

[0061] The liquid crystal structure on the surface of the fiber was confirmed using test fabrics of polyester fabrics treated according to formulation B (Example 5) and formulation D (Comparative Example 5) in Table 1. Confirmation was performed with a transmission electron microscope (60,000 magnifications). Such as figure 1 As shown, Example 5 has a layered liquid crystal structure on the surface of the fiber. Such as figure 2 As shown, in Comparative Example 5, no lamellar structure can be seen.

Embodiment 7、8

[0063] Use the decaglyceryl diisostearate of Table 1, press the formula of Table 3, utilize the exhaust dyeing method [equipment: newmatchmangle (ニユ一マツチチチングル) IPM-1 type: Tsujii dyeing machine industry Co., Ltd., sensitivity 60%, dry 120° C.×2 minutes] The polyester fabric was treated to obtain a test fabric. This test cloth was subjected to a moisture retention test. In addition, the amount of fiber adhesion on the fabric was 1.56%, respectively.

[0064] As a result, as shown in Table 4, the state of restoring the water content of cutin is shown.

Abstract

Provided is a fiber treating agent capable of keeping good stability after applied to clothing, etc., highly safe to the skin, and capable of giving high moisture retention to a fiber structure, and to provide a moisture-retaining fiber structure treated with the same. This fiber treating agent contains a polyglycerol fatty acid ester, wherein the ester is composed of a polyglycerol having a degree of polymerization of >=6 and two or more fatty acids of which the constitutions are identical to or different from each other, and has an HLB value of 6-15. The moisture-retaining fiber structure is given by applying the treating agent to the structure.

Description

technical field [0001] The present invention relates to a fiber treatment agent for imparting moisture retention to fibers and a fiber structure treated therewith. Background technique [0002] For the moisture-retaining fiber treatment agent that imparts moisture retention to the fibrous structure, there are known fiber treatment agents using triodecane (Patent Documents 1 and 2), fiber treatment agents using silk protein, and fibers based on silk particles, for example. Surface treatment (Patent Document 3), and treatment with sericin to improve the hydrophilicity of fibers (Patent Document 4). [0003] In addition, Patent Document 5 proposes a fiber treatment agent including emulsified or microencapsulated fats and oils containing γ-linolenic acid. [0004] On the other hand, in patent document 6, the fiber softening agent containing the sucrose fatty acid ester of HLB13 or more and the polyglycerol fatty acid ester of HLB5-13 is proposed. [0005] Patent Document 1: JP...
