Embodiment Construction

[0015] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following further uses the embodiments to describe the present invention in detail.

[0016] This specific embodiment adopts the following technical scheme: a non-woven material for anti-allergic and fully degradable medical and sanitary use. The preparation method includes the following steps:

[0017] 1. Use air-laid to open the wood pulp fiberboard into a single fiber state, and then use the air-flow method to agglomerate the single fiber on the net curtain, and output the fiber net with a carding machine together with carbon fiber, glass fiber, artificial fiber, and biodegradable fiber. Reinforced to obtain non-woven semi-finished products;

[0018] 2. Soak the semi-finished non-woven fabric obtained in the above step (1) in the starch solution at 25°C for 3 hours, add D2W and EPI, the addition ratio of D2W is 1%, the addition ratio of EPI is...

Abstract

The invention provides an allergy-free and fully-degradable nonwoven material for medical treatment and health care, and relates to the technical field of nonwoven materials. A preparation method of the nonwoven material comprises the following steps: opening and scotching a wood pulp fibreboard into a monofilament state through an air lay; then agglutinating monofilaments on a net curtain through an air flow method; outputting the monofilaments together with carbon fibers, glass fibers, artificial fibers and biodegradable fibers from a fiber net through a carding machine; reinforcing to obtain a semi-finished product of the nonwoven fabric; soaking the semi-finished product in a starch solution; adding a biodegradable additive and few herbaceous plant plants; heating; foaming to form; sequentially soaking in antibacterial liquid and an antistatic treating agent; then drying. The allergy-free and fully-degradable nonwoven material for medical treatment and health care can be naturally biodegraded after use, so that no environment pollution is caused, and the antibacterial effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of non-woven materials, in particular to an anti-allergic fully degradable non-woven material for medical and sanitary use. Background technique [0002] A nonwoven material or fabric is a fibrous material, usually made from natural fibers or man-made materials by mechanically or thermally bonding the fibers. [0003] A nonwoven material consists of several layers of multilayer material, each of which can be made using a spunbond or meltblown process. In the spunbonding process, the raw material is extruded into fine fibers (about a few microns), and the extruded fibers are arranged randomly on the conveyor belt. In the meltblowing process, fibers are extruded and then sprayed onto another layer or directly onto a conveyor belt. These layers are then bonded mechanically or thermally, ie by thermobonding or hydroentangling. In addition, additives such as surfactants, antistatic agents, impregnants, fluoroc...
