Problems solved by technology

[0003] At present, conventional facial masks are generally sea-island-type superfine short fiber masks. Common sea-island-type masks are generally made of polyester (PET) or polyamide (PA), and the sea components compounded with them can be made of polyethylene (PE), polyamide Amide (PA6 or PA66), polypropylene (PP), polyvinyl alcohol (PVA), polystyrene (PS) and acrylate copolymer or modified polyester, etc., the base fabrics are basically ultra-fine short fibers, which cannot exist The technical problem of biodegradation, poor environmental protection, and the strength of ultra-fine short fibers in the existing sea-island masks is relatively low. high technical issues

Abstract

The invention relates to the technical field of mask manufacturing, and particularly provides a preparation method of a degradable superfine mask base cloth. A mask produced by the manufacturing process has the advantage of degradability, an island component of fiber is PLA (polylactic acid), and a sea component is PA6 (polycaprolactam) or PVA (polyvinyl alcohol); and the sea component and the island component are sliced in parallel to form composite trickles, then the composite trickles are gathered together and extruded from spinneret orifices like production of single-component fibers to obtain sea-island filament fibers, and the sea-island filament fibers are subsequently laid and reinforced to obtain the base cloth of the mask. The superfine fiber mask produced by the process manufacturing method disclosed by the invention has the advantage of high fiber strength, mask base cloth with different gram weights can be prepared, and the superfine fiber mask produced by the process manufacturing method disclosed by the invention is good in skin fitting performance and also has a good moisture absorption effect.

Description

technical field [0001] The invention relates to the technical field of mask manufacturing, in particular to a method for preparing a degradable ultrafine mask base cloth. Background technique [0002] At present, mask cloth is the base material used to make masks, mainly used to carry the essence of the mask, among which non-woven fabric is the most common, non-woven fabric, also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics are moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Features. Most of the mask cloth is made of ultra-fine fiber materials and then pressed. The mask can not only soften the cuticle, prevent water evaporation, accelerate the penetration and absorption of nutrients, but also remove dirt and oil on the skin surface, so as to enhanc...
