Problems solved by technology

It has been proved by experiments that its water washing performance is not strong enough and inelastic. The main reason is that the silk fibers are small and dense. When bonding, the adhesive is only sprinkled on the surface of the nonwoven fabric and cannot penetrate into the interior of the nonwoven fabric, resulting in There is no adhesive in the middle part of the non-woven fabric, and the adhesive itself is not strong in washing resistance, and there will be obvious delamination. The thin and ultra-thin non-woven fabrics produced by this method, if used as a disposable sanitary Although the fabric of the product can play a certain antibacterial effect, its antibacterial property is poor. During use, the nonwoven fabric will be delaminated due to moisture absorption, so the nonwoven fabric is far from fully meeting the needs of disposable absorbent products. Hygienic materials not suitable for use as topsheets of disposable absorbent articles

Embodiment Construction

[0012] The invention provides a hygienic material, which adopts silk short fiber as a raw material, and performs screening of the raw material to remove impurities. Then, the sericin and its wax, carbohydrates, pigments, ash and natural impurities in the silk are removed by conventional silk degumming methods such as soap alkali method, synthetic detergent method, and enzyme degumming method. Then, the obtained silk loose fibers are washed with water, and after the water washing is finished, they are dehydrated on a centrifugal dehydrator.

[0013] An optional but not necessary step is to use 30% hydrogen peroxide 10-30g / L, soaking soda 1-6g / L, pH 9.5-10, and treat at 90-99°C for 30-90min , hot wash, cold wash. It is preferable to use fluorescent whitening agent VBL 0.1-0.4g / L, Yuanming powder 1-5g / L, and treat at 60°C for 15-45min.

[0014] The silk fibers are carded and shortened into short silk fibers with an average length of 20-80 mm, preferably 38 mm-58 mm in length. ...

Abstract

The invention relates to a sanitary material. The sanitary material is silk water-jetting non-woven fabric which uses silk short fibers as raw materials and is prepared by the water-jetting technology. wherein in the after-finishing process of the silk water-jetting non-woven fabric, an organic antibacterial agent which contains at least one of double-chain quaternary ammonium salt, biguanides and triclosan is coated on the silk water-jetting non-woven fabric by the on-line coating technology, wherein the dry weight ratio of the consumption of the antibacterial agent to that of the silk water-jetting non-woven fabric is 0.5:1000-5:1000. The silk water-jetting non-woven fabric has the advantages of good comfort property, fineness, smoothness, lightness, softness, good hygroscopic property and ventilation property and refined pearly luster and good safety and stability; in addition ,the 20-minute antibacterial ratio of the silk water-jetting non-woven fabric against bacteria, such as coliform bacteria and candida albicans, is larger than 90-95 percent, has quick, durable, high-efficiency and broad-spectrum antibacterial effects, and has no irritation, no allergic reaction and no corrosion.

Description

technical field [0001] The invention relates to a hygienic material, in particular to a hygienic material with an antibacterial and health-care function. Background technique [0002] The hygienic materials used in the surface layer of disposable absorbent products such as sanitary napkins and diapers generally use non-woven fabrics. Non-woven fabrics are also called non-woven fabrics. The non-woven fabrics used for fabrics have the characteristics of strong hydrophilicity, liquid permeability, softness, and skin-friendly properties. Products made of non-woven fabrics are more suitable for sensitive skin. use. According to different production processes, nonwovens can be divided into hot pressing, hot air, spunlace and other forms. Nonwovens produced by different processes have different performance characteristics. The feel and performance of different fibers produced by the same process are also different. Hot-air nonwovens are soft and fine, and have excellent liquid ...
