Production of non-woven cotton cloth with coating function finishing

Abstract

This invention relates one functional finish non-wovens fabrics of coating staining in 100% cotton and its method. The process for this new cotton non-wovens fabrics is that attach uniformly the functional finishing agent in the form of solution, slurry and bubble to the surface of the non-wovens fabrics by coating staining (the treatment of rotary screen printed James, Roll James, leaching James, bubble James, scraper, transfer, and so on), fix to surface by the pine-drying and the reaction between finish agent and fiber. By the method one cotton non-wovens fabrics in which one side it has protective function (Exhibit 1) of 'Waterproof, anti-alcohol, anti-blood, anti-oil pollution, fire-retardant, anti-rays, anti-static' and in the other side it is with the cotton Fiber characteristics of 'Suction fluid, breathable, comfortable' Compared to the current stains rolling (ie, the entire stain soaked) methods, this invention has the advantages as follows: short time for processes, flexible technology, raw materials and energy saving, low cost, rich colors, forming without damaging non-woven fabrics, non-pilling, finish agent closely attached to the non-woven fabrics without losing.

Description

【Technical field】 [0001] The invention relates to a coated functional all-cotton non-woven fabric and a production method thereof. 【Background technique】 [0002] In daily life, medical operations, special operations, in order to effectively protect the general population, medical staff, special workers, etc. Cloth played a key role. At present, non-woven fabrics are mainly functionally finished by impregnation and padding, that is, the fabric is completely immersed in the finishing agent solution with protective functions, and then rolled and dried to process more non-woven fabrics with protective functions. The following disadvantages: [0003] 1. The process is long and complicated: padding finishing liquid-infrared pre-drying-guide roller drying-stenter drying and other processes; [0004] 2. Soaking fiber with functional finishing agent requires a large amount of bath and sufficient time to make the finishing agent soak and diffuse to the entire fiber, resulting in l...

AI Technical Summary

Problems solved by technology

[0003] 1. The process is long and complicated: padding finishing liquid-infrared pre-drying-guide roller drying-stenter drying and other processes;

[0004] 2. Soaking fiber with functional finishing agent requires a large amount of bath and sufficient time to make the finishing agent soak and diffuse to the entire fiber, resulting in large loss, waste, and increased cost and pollution;

[0005] 3. The functional finishing agent soaks into the fiber and forms a film after curing, which makes the fiber stiff and affects the softness, comfort and drapability of the product;

[0006] 4. The moisture content of the non-woven fabric after padding is about 70%. The long-term stretching and drying of the non-woven fabric in a wet state will cause slippage between the fibers, shrinkage deformation and stretching deformation of the non-woven fabric, and the strength will decrease. There are problems such as fluff;

[0007] 5. The padding method has a long equipment line and is difficult to clean, which is not suitable for small batch production and lacks production flexibility;

[0008] 6. The padding method realizes the liquid-proof performance, and also reduces the hydrophilicity and air permeability, and the wearing comfort is reduced

[0009] 7. The padding method needs to saturate the fibers. Generally, an aqueous solution is used. In the same bath, only functional finishing agents with similar performance can be prepared, so that the product can only be finished with single function or few functions. Multifunctional finishing is very difficult, which limits the diversity of product functions.
