Problems solved by technology

The denim garments treated with the resin finishing solution with the above-mentioned stiffening agent have acceptable three-dimensional effect and bottom retention performance, but relatively poor elasticity and excellent hand feeling.
Polyvinyl acetate emulsion or PVA emulsion is also used as a stiffening agent. After being treated with a resin finishing solution with this stiffening agent, the hand feeling of denim clothing is relatively acceptable, but the three-dimensional effect of cat whiskers is somewhat defective.

Embodiment 1

[0024] (1) Preparation of 14% polyvinyl alcohol emulsion: select polyvinyl alcohol raw materials with a degree of polymerization of 1750 and a degree of alcoholysis of 99.5%. Based on the total weight of the polyvinyl alcohol emulsion, add 86% of water into the reactor, turn on the agitator, and slowly add 14% of flocculent polyvinyl alcohol. After the polyvinyl alcohol is added, stir and heat up to 90-95℃, after fully dissolving, discharge the material, then stir and cool down to room temperature.

[0025] (2) Prepare 23% polyurethane emulsion: add 6.5% emulsifier TX-10 (octylphenol polyoxyethylene ether-10) to the reactor based on the total weight of the polyurethane emulsion, Add 6.5% of O (fatty alcohol polyoxyethylene ether), inject 64% of water, add 23% of polyurethane while stirring, increase the temperature to 70°C, keep the temperature for 90 minutes, cool down and filter the material.

[0026] (3) Preparation of buffer system: Under normal conditions, the best film-formi...

Embodiment 2

[0029] Steps (1), (2), and (3) are the same as in Example 1. In step (4), the polyvinyl alcohol emulsion is 67%, the polyurethane emulsion is 33%, and the rest are the same, and the stiffening agent of this embodiment is prepared.

Embodiment 3

[0031] Steps (1), (2), and (3) are the same as in Example 1. In step (4), the polyvinyl alcohol emulsion is 63.5%, the polyurethane emulsion is 36.5%, and the rest are the same, and the stiffening agent of this embodiment is prepared.

Abstract

The invention relates to a stiffening agent and resin finishing liquid used for crease finishing of jean clothes. The stiffening agent used for crease finishing of the jean clothes comprises the following components, by weight percentage or weight, 60-67% of polyvinyl alcohol emulsion, 33-40% of polyurethane emulsion, and a buffer system of which the weight is 0.006 time of the total weight of the polyvinyl alcohol emulsion and the polyurethane emulsion. The resin finishing liquid used for crease finishing of the jean clothes comprises the following component, by weight percentage or weight, 3-6% of the stiffening agent, 6-18% of crease pressing resin, catalysts with use amount being 1 / 5-1 / 4 of the crease pressing resin, and the balance water. By the adoption of the stiffening agent and resin finishing liquid used for crease finishing of the jean clothes, the elastic recovery performance and crease resistant performance of jeans can be improved; the stereoscopic impression of cat whiskers and three-dimensional cat whiskers of creases is achieved, and durability is also achieved; the color retaining performance and dry and wet friction fastness are improved, a soft feeling is achieved, the cost performance is high, and the requirement for fashionable elements of the jean clothes is met.

Description

Technical field [0001] The invention relates to the field of washing processing (style) finishing of denim apparel, in particular to a stiffening agent used for crumple finishing of denim apparel. Background technique [0002] In recent years, there has been a popular trend in denim clothing-three-dimensional crumpled cat whiskers. Sort out the flat and round natural wrinkles produced in the process of taking the clothes on the trouser tube, trouser body and other parts of the clothes, and stabilize their wrinkle shape. Because they are shaped like cat whiskers, they are called three-dimensional cat whiskers. This style is popular among consumers because of its naturalness, novelty and fashion. [0003] The denim crumpled finishing process has gradually become one of the most conventional techniques in the denim washing industry. Its function is to improve the elastic recovery performance of denim after finishing and crumpling with resin finishing liquid, thereby improving the an...
