Problems solved by technology

At present, the raw materials of non-woven fabrics are mainly PET, PP, ES fibers and viscose fibers, or superabsorbent resins are added, but the thickness, water absorption, cost and biodegradability of disposable non-woven fabrics produced from these raw materials are limited. The performance is still open to question, so there is an urgent need to create an ideal disposable non-woven fabric

Abstract

The invention discloses silk non-woven fabric applicable to baby wet wipes and a preparation method of the silk non-woven fabric. The preparation method comprises steps as follows: (1), impurities in silk fibers are removed, the silk fibers after degumming and drying is placed in a low-temperature plasma apparatus for low-temperature plasma processing, the silk fibers are taken out and impregnated in a surfactant-containing solution for oscillation at the constant temperature, then the silk fibers are taken out, a redundant liquid on the surface is removed, the silk fibers are placed in a drying oven for drying, and the silk fibers subjected to hydrophilic modification processing are obtained; (2), the silk fibers after hydrophilic modification processing and bamboo fibers are teased out and spread to form a silk fiber mesh and a bamboo fiber mesh, the silk fiber mesh is placed above the bamboo fiber mesh, the silk fiber mesh and the bamboo fiber mesh are tightly composited in a spunlace cross lapping mode, and silk / bamboo fiber non-woven fabric with an even or uneven surface is formed; (3), the silk / bamboo fiber non-woven fabric after cutting is left to stand in constant-temperature and constant-humidity space, and the silk non-woven fabric applicable to the baby wet wipes is obtained.

Description

Technical field: [0001] The invention belongs to the technical field of sanitary products, and in particular relates to a silk nonwoven fabric suitable for baby wet wipes. Background technique: [0002] Baby products such as baby wipes, baby diapers, etc. are all disposable sanitary products. Disposable sanitary products are the inevitable product of economic and social development. Earlier, tissue paper was used as a raw material to produce disposable hygiene products, but tissue paper failed to gain popularity due to its poor water absorption and wet strength. With the continuous development of synthetic fibers and science and technology, non-woven fabrics are used as raw materials, and the shape and performance are continuously modified, and disposable sanitary products have been popularized and developed. The application of disposable non-woven fabrics not only greatly improves the hygienic situation, but also is comfortable, convenient and portable, which reduces peopl...
