Problems solved by technology

However, heat treatment at a high temperature requiring high energy is not advisable under the trend of energy saving in the world
In addition, monomers having a fluoroalkyl group are not only expensive, but also difficult to decompose, so the load on the environment is large

Embodiment

[0174] The present invention will be further described below, but the present invention is not limited by these examples.

[0175]

[0176] The mixture having the composition shown in Tables 1 and 2 (the numerical representation (g)) is polymerized by the procedure shown in the following, and the polymer dispersion is obtained.

Synthetic example 1

[0178] Acrylic 20g of acrylate is charged in a 500 ml flask, a PD-430 (manufacturing, polyoxyalkylene ether, HLB = 14.4) (manufactured by Huang Co., Ltd., manufacturing, gauge Oxide oxide ether, HLB = 12.6) 2g, hydrochloromethyl amine hydrochloride 3g, tropopropylene glycol 25g and water 207.70 g, mixed at 45 ° C, and mixed. The mixture is irradiated with ultrasonic waves to disperse all monomers. Next, azo dithis (isobutyl) dihydrochloride was added to the mixture, and the radical polymer was polymerized at 60 ° C for 6 hours under a nitrogen atmosphere, and the polymer was obtained as a non-fluorine water repellent. The concentration of 21% by mass of non-fluorine-based acrylic polymer dispersion.

Synthetic example 2～10

[0180] In addition to the materials described in Tables 1 and 2, polymerization was carried out in the same manner as in Example 1, and as the non-fluorine water repellent, the polymer concentration of the polymer concentration shown in Tables 1 and 2 was obtained. Dispersion.

Abstract

The method for producing a water-repellent fiber product according to the present invention includes a step of mixing at least one non-fluorine-based water repellent selected from the group consisting of acrylic water repellents, silicone-based water repellants, and dendrimer-based water repellents with fibers contact, the fibers contain a group selected from ‑SO 3 M 1 (in the formula, M 1 A monovalent group represented by a monovalent cation), represented by -COOM 2 (in the formula, M 2 represents a monovalent cation) and a monovalent group represented by ‑O‑P(O)(OX 1 )(OX 2 ) (in the formula, X 1 and X 2 Each independently represents at least one functional group among monovalent groups represented by a hydrogen atom or an alkyl group having 1 to 22 carbon atoms).

Description

Technical field [0001] The present invention relates to a method for producing a waterproof fiber article, in more detail, and a method for producing a water-proof fiber article using a non-fluorine water repellent. Background technique [0002] In the past, a fluorine-resistant water repellent containing a fluorine-containing group was known, and the fiber article which imparts the waterproofing to the surface by treating the fiber product or the like by the fluorine-based waterproof agent. Such fluorine-based water repellents are typically produced by polymerization or copolymerization of a monomer having a fluorine group. In order to make the water resistance, the orientation of the fluoroalkyl group is needed, and the fluorine-based waterproof agent is used to attach the heat treatment at a temperature of over 130 ° C after the fluorine water repellent is attached to the fiber article. However, heat treatment under high energy is required is not advisable under the internatio...
