Abstract

Disclosed is development of a single-sided alcohol-resistant and single-sided anti-static medical SMS. The development is characterized by comprising the steps of raw material mixing, melt extrusion,drafting, hot rolling, oiling, drying and cooling shaping. According to YY/T 0506.2-2016 standard of the pharmaceutical industry in China and the European BS EN 13795-1: 2019 standard, the water permeability resistance of the single-sided alcohol-resistant and single-sided anti-static medical SMS non-woven fabric meets the requirement of a water column with the single point value of 60 cm; the medical SMS non-woven fabric has higher barrier, higher water seepage resistance and excellent basic physical properties, the pattern surface can keep excellent alcohol resistance, and the smooth surfacehas favorable antistatic property; the single side of the SMS non-woven fabric has antistatic property and the single side of the SMS non-woven fabric has alcohol resistance through direct productioninstead of an after-treatment mode; and productivity improvement and the like can be achieved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to the development of a single-side anti-alcohol and single-side antistatic medical SMS. Background technique [0002] Surgical gowns can effectively prevent cross-infection of germs and are an important barrier to protect patients and medical staff during surgery. Because polypropylene SMS non-woven fabrics have good mechanical properties and barrier properties, they are widely used in disposable medical surgical gowns. SMS non-woven fabric treated with three anti-alcohol, anti-blood, anti-static can effectively isolate bacteria and pathogen cross-infection, easy to use, safe and hygienic, and is the main material of high-end medical surgical gowns, but the existing three anti-materials It is all through finishing to make it have anti-alcohol and anti-static properties. my country's pharmaceutical industry standard YY / T 0506.2-2016, European standard BSEN 13795-1: 2019 a...
