Problems solved by technology

But this method still has the following defects: one, the process flow is long, the whole process operation is relatively complicated, the process controllability is poor, and the product is damaged greatly, and the products produced are limited to thick and heavy products such as trousers, which is not suitable for Production of high-count shirt varieties
Second, the one-step method of using the same bath for loading materials through the dipping machine cannot guarantee that the single-layer and multi-layer parts of the garment will absorb the same working fluid, which will easily lead to local unevenness of the final garment, that is, uneven shirt strength, color and feel
Third, the high baking temperature will easily cause most white shirts to turn yellow, and at the same time consume a lot of energy, which is not conducive to energy saving and emission reduction
4. There is not enough pressure applied during the shaping process, and the appearance of the seams after washing is poor due to reasons such as seam shrinkage at the seams, which seriously affects the product quality

Embodiment 1

[0013] Embodiment 1: A non-ironing treatment method that can solve the problem of non-ironing cotton shirts, the steps include resin absorption-pre-baking-pressing-baking-cooling: the material of the shirt is an 80 / 2 cotton twill shirt, wherein ① resin The absorption process is to apply the working liquid to the sewn shirt, so that the liquid-carrying rate of the shirt is 70%; the working liquid formula (by mass percentage): the resin is modified dihydroxymethyl dihydroxyethylene urea, and the content is 15% %; the metal salt catalyst is magnesium chloride, and the content is 1%; the fiber protection agent is polyethylene dispersion emulsion, and the content is 2%; the softening agent is amino silicone oil, and the content is 2%; the penetrating agent is a nonionic surfactant, The content is 0.2%; the balance is water, and the pH value of the working fluid is adjusted to 4.5 by glacial acetic acid; ②The pre-drying temperature of the shirt in the pre-drying process is 50°C, so t...

Embodiment 2

[0018]Embodiment 2: The process sequence in this embodiment is the same as that of Embodiment 1. The material of the shirt is a 100 / 2 cotton twill shirt, wherein 1. the resin absorption process is to apply the working fluid to the sewn shirt to make the liquid-carrying rate of the shirt 75%; working fluid formula (by mass percentage): the resin is modified dihydroxymethyl dihydroxyethylene urea, and the content is 20%; the metal salt catalyst is zinc nitrate, and the content is 1.7%; the fiber protection agent is poly Ethylene dispersion emulsion, the content is 3%; the softener is amino silicone oil, the content is 3%; the penetrating agent is non-ionic surfactant, the content is 0.6%; the balance is water, and the pH value of the working solution is adjusted to 4.7; ②The pre-drying temperature of the shirt in the pre-drying process is 60°C, so that the moisture content of the shirt is 35%; The pressure is 5.5kg / cm2, the pressing temperature is 140°C, and the pressing time is...

Embodiment 3

[0023] Embodiment three: the process sequence in this embodiment is the same as that in embodiment one, and the material of the shirt is an 80 / 2 cotton dobby shirt, wherein ① the resin absorption process is to apply the working fluid to the sewn shirt, so that the shirt is filled with liquid The rate is 80%; working fluid formula (by mass percentage): the resin is modified dihydroxymethyl dihydroxyethylene urea, the content is 25%; the metal salt catalyst is zinc chloride, the content is 2.5%; fiber protection agent It is a dispersed emulsion of polyethylene, with a content of 4%; the softener is amino silicone oil, with a content of 3%; the penetrating agent is a non-ionic surfactant, with a content of 1%; the balance is water, and the pH of the working fluid is passed through glacial acetic acid Adjust to 5; ②The pre-drying temperature of the shirt in the pre-drying process is 70°C, so that the moisture content of the shirt is 30%; The applied pressure of ironing is 7kg / cm2,...

Abstract

The invention provides a no-iron treatment method for a cotton shirt, which can solve the problems of yellowing due to overhigh baking temperature and poor seam appearance due to seam shrinkage of the cotton shirt. The method comprises the following process flows: resin absorbing, pre-baking, pressing, baking and cooling, wherein a working solution comprises the following components in percentage by mass: 15 to 25 percent of resin, 1 to 2.5 percent of catalyst and 2 to 4 percent of fiber protective agent; and the pH value of the working solution is regulated to be between 4.5 to 5.0. The process can ensure that seams or pleats of collar, yoke, two sleeves, side seams, a left front panel, a right front panel, a left back panel, a right back panel and other parts of the shirt are flat and fitting, no bulge is generated after the shirt is washed, and all the appearance flatness of products and the appearance of the seams and the pleats are up to the 4.0 level of 'the No-iron Textiles Standard' published by the State Administration of Quality Supervision, Inspection and Quarantine, namely the testing index is higher than 'the No-iron Textiles Standard' by 0.5 to 1 level.

Description

technical field [0001] The invention relates to a post-finishing process for shirts, in particular to a non-ironing treatment method for cotton shirts. Background technique [0002] With the trend of "returning to nature" becoming more and more popular in the field of clothing, pure cotton shirts are deeply loved by consumers for their comfortable wearing, good air permeability, strong hygroscopicity, soft hand feeling, and environmental protection. And the characteristics of easy wrinkling, not quite expanding, and not attractive in appearance during washing have brought a lot of inconvenience to consumers. Therefore, the pure cotton non-ironing shirt that is easy to wash and wear and easy to maintain has emerged at the historic moment, meeting the needs of consumers for comfort, beauty, and convenience in clothing. At present, pure cotton non-ironing shirts all adopt the method of making clothes after non-ironing of fabrics. This method has higher fabric stiffness, but i...
