Abstract

The invention discloses a hydrophilic-lipophilic medical sheath-core type fiber non-woven fabric, and relates to the technical field of non-woven fabrics. The medical sheath-core type fiber is prepared by processing sheath-core type fiber through a spunlace process, the sheath-core type fiber comprises a core layer and a sheath layer, the core layer is modified polyester fiber, and the sheath layer is modified polylactic acid fiber. The prepared non-woven fabric has the excellent hydrophilic and lipophilic properties and good antibacterial and anti-ageing properties and is good in strength andrebound resilience and comfortable in hand feeling; compared with a sheath-core type fiber non-woven fabric which is prepared by directly adopting unmodified polyester and polylactic acid, the tensile strength is increased by 78.2%, the water absorption rate is increased by 47.6%, the oil absorption rate is increased by 64.7%, and then the application direction of the medical non-woven fabric isimproved.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a hydrophilic and lipophilic medical sheath-core fiber nonwoven fabric. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is a kind of fabric formed without spinning and weaving. It just oriented or randomly arranged short textile fibers or filaments to form a web structure, and then used mechanical, thermal bonding or Strengthened by chemical and other methods. Non-woven fabrics are widely used in medical, health and other industries, including wipes, surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc., are mostly made of non-woven fabrics. [0003] Polyester fiber has high strength and resilience, but poor hydrophilicity and lipophilicity, and general hand feeling, and in some specific fields, its strength needs to be further improved. Contents of the invention [0004] Based on the technical...
