Environmental-protection function cloth production method

Abstract

The invention relates to an environmental-protection function cloth production method, which comprises: (A) providing a base cloth, wherein the base cloth is not subjected to dyeing treatment or function processing treatment, and is provided with a bottom surface and a top surface, and the bottom surface and the top surface are oppositely arranged; (B) forming a moisture-permeable and waterproof film layer on the top surface of the base cloth; and (C) forming at least a pattern layer on the moisture-permeable and waterproof film layer surface opposite to one of the bottom surface and the top surface of the base cloth. According to the present invention, the pattern layer is formed by using the printing method providing advantages of water saving, energy saving and environment protection compared to the existing dyeing treatment, such that the appearance of the environmental-protection function cloth can have the color pattern, and the color pattern outline position can be accurately positioned without deformation; and the existing water-repellancy processing treatment using the water-repellancy agent is replaced with the moisture-permeable and waterproof film capable of minimizing the damage and the impact on the human body and the environment while the effects of moisture permeation and water resistance can be achieved.

Description

technical field [0001] The invention relates to a method for making cloth, in particular to a method for making environmentally friendly functional cloth. Background technique [0002] Generally, the fabric base fabric woven by the loom will go through subsequent dyeing and finishing processes to improve its poor appearance, rough touch, and increase various items such as wrinkle resistance, water repellent, and water repellency. proofing), fire proofing, soil repellent and other functions. [0003] The above-mentioned dyeing and finishing process can be divided into three parts: pre-treatment, dyeing and functional processing. The pre-treatment is used to remove impurities on the fibers of the fabric base cloth through desizing, scouring, bleaching and other treatments, so as to facilitate the subsequent dyeing treatment. Dyeing process mainly immerses the pre-treated fabric base fabric in the dyeing solution to absorb the dye to present the color. In addition to the dye,...

Problems solved by technology

[0004] However, most of the chemical auxiliaries used in the above-mentioned dyeing treatment have low biocompatibility, are biotoxic, and even contain carcinogenic heavy metals. Therefore, in the later stage of the above-mentioned dyeing treatment, the fabric base fabric must be washed with a large amount of water for multiple times procedures to avoid chemical additives remaining on the fabric base fabric, and finally the fabric base fabric is heated and dried

[0005] It can be seen from the above description that the dyeing process of the fabric base fabric is not only high in water consumption and energy consumption, but also produces a large amount of sewage containing heavy metals and chemical additives that is difficult to clean. Therefore, the above dyeing process is not environmentally friendly.

Furthermore, most of the chemicals used in the above-mentioned functional processing are also biologically toxic. For example, water-repellent agents such as Teflon and other fluorine compounds are used, which will cause irreversible damage to the human body and the environment that come into contact with them.

[0006] In addition, the pattern formed by the dyeing of the fabric base fabric by the above dyeing process is likely to cause the dye solution to spread out unevenly at the edge of the pattern due to the capillary diffusion of the dye solution by the fibers of the fabric base fabric, resulting in poor positioning accuracy of the dyeing pattern and poor dyeing. Problems such as pattern deformation
