Due to the low output rate of cotton linters and less supply of goods, it currently relies heavily on imports. Whether it is facial masks or wet wipes, they are all disposable consumer consumables, and it is difficult to recycle them; while non-woven fabrics produced by organic solvent spinning process The technical difficulty lies in the spinning process, and the production cost of the above two non-woven fabrics is relatively high
In addition, the thin and light mask is not easy to stretch during use, and it is easy to tear

Embodiment 1
[0030] Embodiment 1 (referred to as S1, the same below)
[0031] The preparation method of embodiment 1 frivolous all-cotton nonwoven fabric, comprises the following steps:
[0032] S1, disposing cotton fiber, cleaning, carding and laying net to obtain cotton fiber web;
[0033] S2, Spunlace the cotton fiber web obtained in S1 to obtain a grammage of 20g / m 2 spunlace non-woven fabric;
[0034] S3, introducing the non-woven fabric that has been spunlace once into the lye tank for mercerizing treatment, and then exporting it to be boiled and rinsed after the liquid is squeezed;
[0035] S4, immersing the mercerized non-woven fabric with water in a cellulose ionic liquid solution at room temperature, and then spunlacing and drying for the second time after squeezing the liquid;
[0036] S5, washing with water and drying for the second time to obtain a light and thin cotton non-woven fabric product.
[0037] In Example 1, the concentration of caustic soda in the lye in S3 is 2...
Embodiment 2-3
[0039] Embodiment 2-3 is based on embodiment 1, difference is the process parameter of mercerizing process:
[0040] Example 2 The concentration of caustic soda in the lye in S3 is 250g / L, the temperature of the lye is 20°C, and the mercerizing treatment time is 20s; the tension of the non-woven fabric in the lye tank in S3 is 0.5 bar, and the liquid carrying rate in S3 is 70 %;
[0041] Example 3 The concentration of caustic soda in the lye in S3 is 260g / L, the temperature of the lye is 15°C, and the mercerizing treatment time is 30s; %;
Embodiment 4-5
[0043] The difference between embodiment 4-5 and embodiment 3 is the spunlace process condition:

Abstract
The invention discloses a preparation method of light and thin all-cotton non-woven fabric. The preparation method includes the following steps that S1, cotton fibers are arranged, blowing, combing and lapping are carried out, and cotton fiber nets are obtained; S2, the cotton fiber nets obtained in S1 are subjected to primary spunlace, and spunlace non-woven fabric with the gram weight of 20-28 g/m<2> is prepared; S3, the non-woven fabric obtained after primary spunlace is guided into a lye tank for mercerization, and after mangling is completed, the non-woven fabric is guided out for scouring, bleaching and washing; S4, the mercerized non-woven fabric carrying water is soaked in a normal-temperature cellulose ionic liquid solution, and after mangling is completed, the non-woven fabric issubjected to secondary spunlace and drying; S5, the non-woven fabric is subjected to washing and secondary drying, and the finished light and thin all-cotton non-woven fabric is obtained. The all-cotton non-woven fabric is adopted as the raw material, and through mercerization, then by means of binding points formed after regenerated cellulose is left in the cotton nets of the non-woven fabric, the obtained all-cotton non-woven fabric is light, thin, rich in gloss and smooth in touch, and has the good hygroscopicity and tensile property. The invention further discloses the light and thin all-cotton non-woven fabric and application thereof.
Description
technical field [0001] The invention belongs to the technical field of non-woven fabrics, and in particular relates to a preparation method of light and thin all-cotton non-woven fabrics, non-woven fabrics and applications. Background technique [0002] Spunlace non-woven fabric is to spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. The obtained fabric is spunlace non-woven fabric. Its fiber raw materials come from a wide range of sources, such as polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. Compared with needle-punched non-woven fabrics, spunlace non-woven fabrics have a smaller grammage and are suitable for use as cosmetic consumables such as masks and medical dressings. [0003] Commonly used sticking masks can be divided into non-woven masks, silk ma...
