Abstract

The invention discloses a fluffy and soft skin-friendly medical non-woven fabric and a preparation method thereof. PP and PE are used as spinning raw materials and an elastic copolymer is mixed in theraw materials. The preparation method specifically comprises the following steps that two-component spunbond equipment is adopted for production, and fiber-grade spinning PP slices and spinning PE slices are taken as the spinning raw materials, wherein the PP is taken as a core layer and the PE is taken as a skin layer, the elastic copolymer is uniformly mixed, the PE layer with a lower melting point is melted to generate bonding in a hot rolled reinforcement process, and a melt passing through a spinning box body is distributed to form a double-component filament of a skin-core structure, and is cooled and stretched to form a net on a receiving device; the generated net is subjected to a hot rolling process, a specially designed hot roller is adopted, so that the PE on the surface layerof the net is melted, a bonding point is formed between fibers on the net, and then the net is consolidated to form the non-woven fabric; and the prepared non-woven fabric is subjected to a solvent after-finishing process, and the non-woven fabric is subjected to single-sided coating by adopting an antistatic agent.

Description

technical field [0001] The invention relates to the technical field of medical nonwoven fabrics, in particular to a fluffy and soft skin-friendly medical nonwoven fabric and a preparation method thereof. Background technique [0002] Spunbond technology is a type of nonwoven spinning web technology that has developed rapidly in recent years. It is defined as using the principle of chemical fiber spinning (currently mainly melt spinning) to make fibers directly in the process of polymer spinning. It is laid into a web, and then the web is reinforced by mechanical, chemical or thermal methods to form a non-woven fabric. Currently, spunbond non-woven fabrics such as polypropylene, polyester, and polyamide are commonly used. [0003] During medical procedures, hand sanitizers are required to be worn under surgical gowns. However, the hand washing clothes produced by the existing technology are not skin-friendly enough, and there is still a lot of room for improvement in terms o...
