Embodiment Construction

[0018] The present invention provides a process for producing a composite nonwoven fabric special for antibacterial medical and health care. The nonwoven fabric is composed of a first fiber web, a first meltblown layer, a second meltblown layer, a second fiber web, and a third fiber that are sequentially stacked. Net composition, including the following steps:

[0019] Step 1: The first fiber web, the second fiber web, and the third fiber web are continuously processed in their respective procedures;

[0020] Step 2: Lay the first meltblown layer and the second meltblown layer sequentially on the continuously processed first fiber web, and the meltblown of the first meltblown layer and the second meltblown layer are respectively completed in their respective processes;

[0021] Step 3: The second fiber web and the third fiber web are sequentially overlapped and laid on the first fiber web that has been overlapped twice;

[0022] Step 4: Hot-rolling and strengthening the overlapped fir...

Abstract

The invention discloses a special bacteriostatic medical sanitary compound non-woven fabric production process which includes the steps: firstly, continuously processing a first fiber net, a second fiber net and a third fiber net on corresponding working procedures; secondly, sequentially laying a first melt blown layer and a second melt blown layer on the continuously processed first fiber net, and melting and blowing the first melt blown layer and the second melt blown layer on corresponding working procedures; thirdly, sequentially stacking and laying the second fiber net and the third fiber net on the first fiber net melt blown and laid twice; fourthly, hot rolling and strengthening the first fiber net, the second fiber net and the third fiber net after overlapping. According to the method, the first fiber net, the first melt blown layer, the second melt blown layer, the second fiber net and the third fiber net are compounded on line by a one-step method, and a compound non-woven fabric has good antibacterial property and breathability and high barrier property and hydrostatic pressure resistance.

Description

【Technical Field】 [0001] The present invention relates to the technical field of sanitary materials, especially the technical field of composite non-woven fabric production technology. 【Background technique】 [0002] In recent years, in order to prevent indirect infection caused by bacterial penetration and virus cross-infection, the requirements for medical protective materials have become higher and higher. In developed countries such as Europe, America and Japan, the research on medical protective products started earlier, and the materials used in medical treatment, especially surgical gowns, surgical drapes and isolation gowns, have gradually shifted to disposable materials. Most of the non-woven fabrics for medical and health use currently on the market do not have antibacterial effects, and the product uniformity is poor, resulting in poor product functionality and comfort. [Content of the invention] [0003] The purpose of the present invention is to solve the problems in...
