Problems solved by technology

[0002] In recent years, various functional knitted fabrics have emerged in an endless stream. Among them, knitted fabrics with unidirectional moisture transfer function are favored by people because they can quickly conduct moisture and at the same time ensure that the inner layer of the fabric in contact with the skin is dry quickly, but it also has the outer layer of the fabric. The disadvantage of affecting the appearance of the fabric after absorbing moisture on the surface; the fabrics with invisible printing function appearing on the market at present, which press special invisible printing paste on the outer surface of the fabric, so that the surface of the fabric only shows printing when it meets water Therefore, if the one-way moisture-wicking function is combined with the invisible printing function, the fabric can not only keep the inner layer of the fabric dry quickly, but also show the printed pattern after the outer layer of the fabric absorbs moisture without affecting the appearance
However, fabrics with combined functions of unidirectional moisture transfer and invisible printing have not yet appeared on the market. The reason is that the multiple high-temperature treatments in the process of unidirectional moisture transfer treatment and invisible printing will seriously affect the color fastness of the fabric. On the other hand, in the process of processing, the one-way moisture-conducting paste and the invisible printing paste will interact and interact, which will reduce the moisture absorption effect of the fabric's one-way moisture-conducting paste, and the pattern of the invisible printing will not be easy to appear, such as the one-way moisture-conducting paste Thickeners are used in both the material and the invisible printing paste. After completing the one-way moisture-wicking finishing process of the fabric, the thickener in the one-way moisture-wicking paste is attached to the cloth surface, and in the subsequent invisible printing process, the invisible printing paste The same thickener in the previous one-way moisture-wicking slurry will inevitably have an effect on the thickener in the previous one-way moisture-wicking slurry, so that the moisture absorption effect of the fabric after the invisible printing process will be severely reduced and the unevenness will be greater

Abstract

The invention provides single-way wet-conducting and invisible printing complex-function fabric which not only has excellent single-way wet-conducting performance, but also can show the pattern of invisible printing after the outer layer of the fabric is wet, and is attractive and practical. The single-way wet-conducting and invisible printing complex-function fabric comprises a textile, wherein the front surface of the textile is embossed with a water-repellent invisible printing paste layer, while the back surface of the textile is embossed with a single-way wet-conducting paste layer. The invention also provides a processing technology which can effectively reduce the influence of multiple times of high temperature treatment on the color fastness of the textile during the finishing of the single-way wet-conducting function of the textile and the treatment of the invisible printing as well as the interaction between the single-way wet-conducting paste and the invisible printing paste during the processing, and also can ensure the excellent single-way wet-conducting and invisible printing functions of the textile. The processing technology comprises the following steps of: (1) concocting, embossing and drying of the single-way wet-conducting paste; (2) concocting, embossing and drying of the invisible printing paste; (3) drying and shaping of the textile; and (4) low-temperature shaping of the textile.
