Abstract

The invention discloses a preparation method of spandex / nylon-6 two-component medical spunlaced non-woven wiping cloth, and relates to the technical field of preparation of non-woven fabrics. The preparation method comprises the following steps: ultrasonically washing a spandex / nylon-6 two-component spunlaced non-woven cloth substrate with acetone and distilled water, then immersing in a sodium hydroxide solution, taking out, drying in the air, immersing in formaldehyde added with phosphoric acid, and carrying out a reaction to obtain a pretreated non-woven cloth substrate; soaking the pretreated non-woven cloth substrate into an ethyl acetate solution of 2-mercaptopropyltriethoxysilane, carrying out a reaction, taking out, drying, and adding the product into ethanol containing N, N-methylenediacrylamide, butyl methacrylate and titanium dioxide nanoparticles, soaking, taking out, then soaking in a photoinitiator solution, taking out, irradiating with ultraviolet rays, washing, and drying. The spandex / nylon-6 two-component medical spunlaced non-woven wiping cloth prepared by the method has very good hydrophilia, lipophilicity and antibacterial properties, so that the application value of the medical spunlaced non-woven wiping cloth is improved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric preparation, in particular to a method for preparing a spandex / nylon 6 two-component medical spunlace non-woven wiping cloth. 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] Spandex / nylon 6 two-component spunlace nonwoven fabric has excellent properties such as high strength, good air permeability, good elasticity and good wear resistance, and can be used as a high-grade wiping cloth. ...
