Embodiment 1

[0023] The polypropylene spunbonded nonwoven fabric is subjected to two dipping and two rolling through the padding tank of the finishing solution. The contents of chitin and silk fibroin in the finishing solution are both 1%, the WH binder is 5%, and the bath ratio is 1:50 , the temperature is 25°C, the rolling ratio is 100%, then pre-baked (70°C), and baked (130°C). The nonwoven fabric can effectively kill 83.4% of Escherichia coli E.coli and 80.6% of Staphylococcus aureus S.aureus, and the hydrophilicity has increased by 4.6 times.

[0024] Antibacterial test method:

[0025] Take functionally finished non-woven fabrics and unfinished non-woven fabrics with a diameter of 1 cm, sterilize with ultraviolet radiation (irradiation time is 30 minutes), soak in sterile water; put the samples into sterile cell culture dishes respectively , followed by adding 50 microliters of bacterial culture solution (10 6 CFU / ml), and cultivated in a 37°C incubator for 2 hours; add 1 ml of pho...

Embodiment 2

[0029] The polyester spunlaced nonwoven fabric is subjected to two dipping and two rolling through the padding tank of the finishing solution. The content of chitin in the finishing solution is 2%, the content of sericin is 5%, the WH binder is 10%, and the liquor ratio is 1 : 50, the temperature is 20°C, the scrap rate is 100%, then prebaked (70°C), and baked (125°C). The nonwoven fabric can effectively kill 85.7% of Escherichia coli E.coli and 82.3% of Staphylococcus aureus S.aureus, and the hydrophilicity has increased by 6.9 times.

Embodiment 3

[0031] The 70 / 30 viscose / polyester spunlaced nonwoven fabric is subjected to two dipping and two rolling through the padding tank of the finishing solution. The content of chitin in the finishing solution is 5%, the content of silk fibroin is 3%, and the WH binder is 10 %, the bath ratio is 1:50, the temperature is 40°C, the rolling ratio is 100%, then pre-baked (70°C), and baked (155°C). The nonwoven fabric can effectively kill 88.1% of Escherichia coli E.coli and 86.3% of Staphylococcus aureus S.aureus, and the hydrophilicity has increased by 4.2 times.

Abstract

The invention discloses an antisepsis and hydrophilous non-woven fabric that is coated and covered with fibroin and chitin; the invention further discloses a preparation method of the non-woven fabric, which comprises following steps: the non-woven fabric is doubly dipped and doubly rolled in a finishing solution that contains the fibroin and the chitin at the temperature of 20 to 40 DEG C, and then baked and fixed at the temperature less than 160 DEG C. By coating and covering the fibroin and the chitin onto the surface of the non-woven fabric, the non-woven fabric of the invention is provided with hydrophilous, bacteriostasis and sterilization effects without obvious influence to the appearance. The produced non-woven fabric can be used for disposable medical and health materials.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to an antibacterial and hydrophilic nonwoven fabric, a preparation method and application thereof. Background technique [0002] Due to the processing characteristics and product cost of some medical and sanitary nonwovens, synthetic fibers such as polyester and polypropylene have been mostly used for a long time, resulting in poor hydrophilicity of the product; It has very high antibacterial requirements. Therefore, it is imperative to develop nonwovens for medical and sanitary use with hydrophilic and antibacterial properties. [0003] Improving the hydrophilic and antibacterial properties of nonwovens and fibers can be carried out through physical and chemical methods, such as raw silk modification, surface graft modification, functional finishing (such as padding or dipping), etc. Among them, the functional finishing method is simple and low-cost, and can increa...
