Description

A kind of novel antibacterial textile fabric specially used for babies and preparation method thereof

Technical field:

The invention belongs to the technical field of textile materials, and in particular relates to a novel antibacterial textile fabric specially used for babies and a preparation method thereof.

Background technique:

Baby textiles are specially developed for newborn babies and are suitable for their special physiological characteristics. With the advancement of science and technology and the enhancement of people's awareness of their own health protection, baby textiles have begun to develop from the initial requirement of 100% pure cotton to functional performance, subdivision, serialization, and green production processes.

Antibacterial textiles are mainly obtained in two ways, one is to modify the fiber raw materials to make the fiber raw materials have antibacterial properties, and the other is to carry out antibacterial post-finishing processing on textiles. The first method is mainly to mix antibacterial agents into the spinning dope to prepare antibacterial fibers, or to blend antibacterial fibers with other fibers, and then weave to form fabrics with antibacterial functions; the second method is mainly through spraying, dipping, Padding, coating, etc. to obtain fabrics with antibacterial function.

The skin of newborn babies is particularly delicate, sensitive to the external environment, poor in body self-regulation ability, and vulnerable to external viruses, etc. Therefore, antibacterial textiles for babies need to screen green and harmless textile auxiliaries while enhancing the antibacterial function of textiles for babies. Ensure that no harmful substances remain, and ensure that the antibacterial textiles for babies are both comfortable and healthy, and meet the special physiological requirements of newborn babies.

Chinese patent CN10286455A (disclosure date 2013.1.9) discloses a strong antibacterial multifunctional blended interwoven fabric, including warp and weft, the warp is a blended yarn of organic combed cotton and seaweed fiber, and the weft is a blend of bamboo fiber and silver fiber Yarns, warp and weft yarns adopt a four-up-down twill weave as the organizational structure to obtain a multi-functional blended interwoven fabric with high-efficiency sterilization, deodorization, moisture absorption, breathability, comfort and softness, which can be used to make baby clothes. Chinese patent CN103535870A (disclosure date 2014.1.29) discloses an antibacterial and mildew-proof cotton cloth, comprising an antibacterial and mildew-proof layer and a body layer. The antibacterial and mildew-proof layer is placed on the upper part of the body layer, wherein the antibacterial and mildew-proof layer is regenerated from soybean or nano antibacterial Composed of protein fiber and ethyl vanillin antibacterial agent, the body layer is made of cotton fiber and glass yarn. This antibacterial and anti-mildew cotton cloth can keep the microorganisms that use sweat and dirt as the source of nutrition during the wearing process to keep the clothes hygienic. Suitable for making baby clothes and underwear. Chinese patent CN104652133A (disclosure date 2015.5.27) discloses antibacterial, deodorant and anti-mite baby bedding fabrics, the combination of microgelatin, polyurethane emulsion and magnesium chloride formed by anti-mite agent and urea-formaldehyde resin wall material is used as Anti-mite agent, antibacterial agent and organic silicon quaternary ammonium salt are used as antibacterial agent, and micronized carbon is adhered on the surface of the fabric and softened to obtain antibacterial, deodorant, and anti-mite baby bedding fabrics that are washable.

It can be seen from the above prior art that there are not many antibacterial textiles for babies at present. Most of them use ordinary antibacterial fabrics selectively for baby clothes, and most of them use fibers with antibacterial properties or antibacterial agents to give fabrics antibacterial properties. Chemical textile auxiliaries are used to improve the durability of antibacterial fabrics, but they have not been screened for the characteristics of newborn skin, and the prepared fabrics cannot meet the needs of special physiological characteristics of newborn babies. Therefore, it is very necessary to develop a special antibacterial fabric for babies. fabric.
