AI Technical Summary

Problems solved by technology

The specific performance is that the film-forming temperature of the auxiliary agent is very high, most of which are higher than 145°C, which does not match the antistatic agent used on the non-woven fabric, and the simultaneous use of the antistatic agent will weaken the antistatic effect of the non-woven fabric or simply offset it.
In addition, it has a great influence on hydrostatic pressure, directly destroying the index of hydrostatic pressure
Due to the hydrophobicity of polypropylene itself, it is difficult to apply functional agent additives to non-woven fabrics, and it is impossible to carry out large-scale production

Abstract

The present invention relates to a kind of functional non-woven fabric with functions of resisting alcohol, oil, plasma, static electricity and permeation. The functional non-woven fabric is produced through dipping non-woven fabric in functional assistant liquid, rolling to eliminate redundant assistant, stoving and winding. The functional assistant liquid is water solution with waterproofing agent 25-30 g / l, antistatic agent 2-4 g / l and seepage agent 0.5-1.5 g / l. The waterproofing agent consists of acrylic fluoride, polymethyl acrylic acid, glycol and water in certain weight proportion; the antistatic agent consists of alkyl phosphate and water in certain ratio; and the seepage agent consists of polyglycol, sorbitan, oleic acid mixture, n-decyl alcohol and water in certain weight proportion. The roller has rolling speed of 25-35 m / min and rolling pressure of 3-5 kgf / sq cm; and the stoving temperature is 135-150 deg.c.

Description

Technical field: [0001] The invention relates to an anti-alcohol, anti-plasma, anti-static, anti-permeation functional non-woven fabric. It is mainly suitable for making medical disposable surgical gowns, surgical caps, etc. It belongs to the field of medical hygiene materials and clothing. Background technique: [0002] The functionally finished non-woven fabric has the properties of bacteria isolation and breathability. The post-treatment process of non-woven fabrics is similar to the post-treatment process of textiles, from unwinding → dipping and rolling → drying → winding. [0003] The key to functional non-woven fabrics is to find the best impregnating solution formula, so that the function can be added without destroying its original function, especially the hydrostatic pressure, as well as the hand feeling and air permeability. [0004] After the post-treatment test of non-woven fabrics with functional additives originally used in textiles, it was found that they ...
