Description

  The present invention relates to a method for applying a fiber treatment agent, a fiber material, and a fiber product, and more specifically, a method for applying a high-performance fiber treatment agent to a fiber material such as polyester and a fiber product, and a fiber treatment using the method. The present invention relates to a fiber material and a fiber product to which an agent is applied.

  In recent years, polyester is used for polyester fiber processing, non-woven fabric, etc., or for blending and union with other fibers, and the proportion of polyester used in the textile industry has increased. Along with this, high-performance fiber treatment agents are applied to polyester fibers.

  As described above, when a fiber treatment agent is applied to polyester fibers, a binder is used. As a binder currently used, for example, an acrylic emulsion (Light Epoch S manufactured by Kyoeisha Chemical Co., Ltd.). -85), heat-reactive urethane resin (TX13-72 manufactured by Kyoeisha Chemical Co., Ltd.) as the blocked isocyanate, and fatty acid metal salt / polyoxyethylene alkyl ether (F-12 manufactured by Kyoeisha Chemical Co., Ltd.) as the catalyst. In the case of the above materials, water-dispersed urethane resin (Daiichi Kogyo Seiyaku Superflex), or in the case of non-woven fabric, ethylene vinyl acetate resin (Showa Polymer Polysol) is used. At present, the effect of the binder is not achieved. All of these plural materials have problems as fiber binders in terms of safety, environmental properties, and processability, and various improvements and studies have been made.

  A method of applying a fiber treatment agent to the above fiber binder by heat treatment at a relatively low temperature of about 80 to 200 ° C. from a viewpoint of safety, environmental properties, production efficiency in the fiber treatment process, and energy saving. Has come to be desired. As the fiber binder that can satisfy such conditions, an amino acid-based binder exhibiting favorable characteristics with respect to safety, environmental performance, productivity, and energy saving is preferable.

Recently, as in the antistatic agent described in Patent Document 1, an antistatic effect can be obtained by spray-coating a polyglutamic acid sodium salt of an amino acid polymer onto a polyester cloth or the like. It is known that the antibacterial effect is obtained by adding a cationic activator, a quaternary ammonium salt), but this amino acid polymer is contained in an antistatic agent and is intended to function as a fiber binder. It was n’t.

  In the case of a polyester woven fabric, the fiber material or fiber product containing an amino acid polymer as a binder and the high-performance fiber treatment agent are thermally bonded at a temperature of about 120 ° C. to 200 ° C. for about 1 minute to 5 minutes. . In the case of a polyester-based non-woven fabric, heat bonding is performed at a temperature of about 80 ° C. to 110 ° C. for about 3 minutes to 10 minutes.

In particular, N-cocoyl fatty acid arginine ethyl ester / pyrrolidone carboxylate (abbreviation “CAE • PCA”, manufactured by Ajinomoto Co., Inc.) is the best.

  Further, the quaternary ammonium chloride salt may be either a two-chain or three-chain type, but is preferably a dialkyldimethylammonium chloride, and may further be a distearyldimethylammonium chloride.

  In addition, a general solvent may be used as the other compounding agent for the amino acid derivative and the quaternary ammonium chloride salt. For example, a mixed solution obtained by emulsifying and dispersing isopropyl alcohol or ethylene glycol in water as a solvent is preferably used. Can be used. The fiber treatment agent is not limited to the above mixed solution, and may be a powder.

  In addition, although the binder comprised by the amino acid polymer can be used also when heat-bonding a polyester fiber and manufacturing the nonwoven fabric, it can be used widely also for the other heat bonding application.
