Method for processing fabric of surgical gown with permeability-resisting protection function

Abstract

The invention discloses a method for processing the fabric of a surgical gown with a permeability-resisting protection function. The method comprises the steps of nano-sol pretreatment, low-temperature normal-pressure air plasma treatment, chemical permeability resisting agent treatment and ultraviolet radiation. The fabric processed by the method disclosed by the invention achieves the effects of resisting the permeability of blood, alcohol, water and the like, and meets the protection requirements of the fabric of the surgical gown: the water repellency level is 8, the oil repellency level is 7, the alcohol repellency level is 10, the blood contact prevention angle is 126.2 DEG, the strong retention rate is 92.6%, and the permeability retention rate is 95.3%.

Description

technical field [0001] The invention relates to a method for processing surgical clothing fabrics with anti-seepage protection function. Background technique [0002] my country promulgated GB19082-2003 "Technical Requirements for Medical Disposable Protective Clothing" on April 29, 2005, stipulating that medical protective clothing must have liquid barrier properties (including water resistance, synthetic blood penetration and water level). Barrier properties can be subdivided into liquids (such as water, alcohol, blood, oil, etc.). Only when medical materials can well block the infiltration of the above liquids can they protect medical staff from bacterial infection and greatly reduce the risk of infection during surgery. infection rate of patients. In our country, due to the low level of consumption, the consumption concepts of patients and medical staff, as well as related laws and regulations are not perfect and perfect, resulting in a lack of domestic knowledge on the...

AI Technical Summary

Problems solved by technology

Due to the low level of consumption in our country, the consumption concepts of patients and medical staff and related laws and regulations are not perfect and perfect, resulting in a lack of knowledge about the use of medical protective equipment in China

[0003] C currently used for impermeability 8-10 There are internationally banned PFOS (perfluorooctane sulfonyl) and PFOA (perfluorooctanoic acid) in fluorine-containing finishing agents, which are not conducive to environmental protection

And in the general finishing process, it is necessary to bake the finishing agent at high temperature to achieve the effect, but some non-woven fabrics used in surgery are not resistant to high temperature, and the mechanical strength drops seriously, which affects the wearing performance.
