Problems solved by technology

[0004] However, in fluoroalkyl-containing polymers with fluoroalkyl carbon atoms of 6 or less to deal with environmental problems, the effect of preventing bleeding when coating synthetic resins is low, resulting in easy generation of synthetic resins on the opposite side of the cloth substrate. the problem of infiltration
[0005] In addition, when attaching a synthetic resin film, the adhesive agent permeates into the fabric, resulting in a weakened adhesive effect, resulting in a decrease in the peel strength of the synthetic resin film.

Embodiment 1

[0193] Add C to a 1 L autoclave 6 f 13 CH 2 CH 2 OCOCCl=CH 2 (C6α-Cl) 179g, stearyl acrylate 25g, tripropylene glycol 75.8g, pure water 446g, polyoxyethylene lauryl ether 12.7g, polyoxyethylene oleyl ether 2.47g, polyoxyethylene isodeca After heating 5.05 g of trialkyl ether and 2.66 g of dialkyl (tallow) dimethyl ammonium chloride at 60° C., they were emulsified and dispersed using a high-pressure homogenizer. After emulsification, 0.63 g of lauryl mercaptan was added, and 60 g of vinyl chloride was pressurized and filled. Furthermore, 1.92 g of 2,2- azobis(2-amidinopropane) dihydrochloride was added, and it was made to react at 60 degreeC for 3 hours, and the aqueous dispersion liquid of a polymer was obtained. The characteristics of the aqueous dispersion liquid whose concentration was adjusted with pure water so that the solid content concentration might become 30 weight% were measured. The results are shown in Table A.

Embodiment 2

[0195] Except having added 1.25 g of lauryl mercaptan after emulsification, the dispersion liquid of the polymer was obtained by the method similar to Example 1.

Embodiment 3

[0197] Except having added 1.88 g of lauryl mercaptan after emulsification, the dispersion liquid of the polymer was obtained by the method similar to Example 1.

Abstract

The present invention is a treatment agent for a moisture-permeable fabric having excellent moisture permeability, water resistance and launderability. The treatment agent comprises a fluorine-containing polymer having repeating units derived from: (a) a fluorine-containing monomer represented by the formula, CH2=C(-X)-C(=O)-Y-Z-Rf [wherein, X is a monovalent organic group excluding methyl groups, or a halogen atom, Y is -O- or -NH-, Z is a directly-bonded or divalent organic group, and Rf is a fluoroalkyl group with 1 to 6 carbons]; (b) a halogenated olefin monomer; and (c) a fluorine-free monomer that is used as necessary, does not have a fluorine atom, and has at least one carbon-carbon double bond. The dynamic viscoelasticity of the fluorine-containing polymer at 160°C is at least 100 Pa.s.

Description

technical field [0001] The present invention relates to a moisture-permeable waterproof fabric that can be used as clothing, waterproof sheets, shoes, gloves, and the like. Background technique [0002] Conventionally, various techniques have been proposed regarding moisture-permeable waterproof fabrics (for example, Japanese Patent Publication No. 60-47955 and Japanese Patent Publication No. 4-18066). [0003] Fluorine-containing polymers not only impart water and oil repellency and water pressure resistance to fabrics, but are also used as anti-bleeding to prevent synthetic resins from oozing to the opposite side of the fabric base when coating synthetic resins to form a moisture-permeable waterproof layer. agent. [0004] However, in fluoroalkyl-containing polymers with fluoroalkyl carbon atoms of 6 or less to deal with environmental problems, the effect of preventing bleeding when coating synthetic resins is low, resulting in easy generation of synthetic resins on the o...
