Fabric warning sign with service life prompting function and manufacturing method thereof

Abstract

The invention provides a fabric warning sign with a service life prompting function and a manufacturing method thereof.The fabric warning sign with the service life prompting function is characterized in that skin-core structure composite filaments, vat dye dyed cellulose fibers and white cellulose fibers are used as raw materials, through three-layer fabric weave design, different chlorine bleaching resistance and oxygen bleaching resistance of the materials and the dye are utilized, and the materials are combined from outside to inside, so that the service life of the fabric warning sign is prompted. Therefore, the prepared fabric structure shows the characteristic that the fabric structure turns yellow from blue and then turns red along with the increase of the use frequency and the use time from outside to inside, and the fabric structure has the function of prompting the service life. The invention provides a three-layer fabric design method for reflecting different use time, and provides a method for determining the relationship between the chlorine bleaching resistance and the oxygen bleaching resistance of the material and the dye and the use time, thereby having strong practicability and meeting the actual use requirements of different fabrics. The preparation method, the principle and the production process are simple and easy to implement, and the preparation method is suitable for large-scale and industrial production.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a fabric warning label with a service life prompt function and a manufacturing method thereof. Background technique [0002] At present, the sanitary condition of hotel linen is not uncommon. How to use healthier and safer linen and replace linen regularly is an important issue for hotels to improve their service quality and service safety. However, at present, there are two common criteria for judging the replacement of linen: first, through the appearance of the linen, such as holes, broken edges, etc., to be replaced regularly; second, through the method of embedding the production date through the washing label . Although the above two methods can serve the purpose of changing the linen, there are problems in both scientific and health aspects. The first method is not broken and not replaced. Before the replacement, the linen may have stains that penetrate in...

AI Technical Summary

Problems solved by technology

Although the above two methods can achieve the purpose of changing the linen, there are problems in terms of science and health.

The first method is not broken and not replaced. Before the replacement, the linen may have stains that penetrate into the fiber due to long-term use, which is difficult to remove, and there is a risk of health in later use.

Although the second method is to implant the production date, since each batch of linen is not put into use on the production date, and the frequency of use is also different, it is impossible to track the use of linen scientifically, effectively and truly cycle status

[0003] It is precisely because of the deficiencies pointed out above in the existing judging criteria for changing linen that there are many hidden problems in the hygienic condition of hotel linen, and there is a risk of breeding bacteria, which leads to health risks for consumers during use
