Abstract

The invention discloses a medical non-woven fabric with high permeability. The medical non-woven fabric is characterized in that base cloth is prepared by modified alginate fibers and viscose fibers,and the base cloth is prepared by finishing through a finishing liquid; a mass ratio of the modified alginate fibers to the viscose fibers is 1: 2-3; the non-woven fabric is prepared by the followingsteps of step 1, mixing the modified alginate fibers and the viscose fibers according to the mass ratio, carrying out opening, impurity removal and net forming on blowing-carding equipment and obtaining the base cloth on a non-woven needled sample weaving machine; and step 2, carrying out finishing on the base cloth in the finishing liquid to obtain the non-woven fabric. According to the medical non-woven fabric, the non-woven fabric prepared by mixing the modified alginate fibers and the viscose fibers is used as the base cloth, the modified alginate fibers and the viscose fibers have excellent air permeability and skin friendliness, and are made in a weaving mode, so that the obtained base cloth has extremely high air permeability; the base cloth is finished through the special finishingliquid, so that the antibacterial property and softness of the non-woven fabric can be effectively improved; and the high-permeability non-woven fabric with the excellent antibacterial effect is obtained and is suitable for the medical field.

Description

technical field [0001] The invention belongs to the field of non-woven fabrics, and in particular relates to a highly air-permeable medical non-woven fabric. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. A new type of fiber product with soft, breathable and planar structure. The advantage is that it does not produce lint, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven fabrics Cloth bags are easy to form and inexpensive to make. Medical non-woven products are medical and sanitary textiles made of chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fi...
