Embodiment 1

[0077] The spunbond main raw material of the present invention is polypropylene with a melt index (MFR) of 35 g / 10 minutes. In order to reflect the blue color, 3% by weight of a master batch of highly concentrated phthalocyanine blue dye is added. Melt and mix the main raw materials and masterbatch sheets in the extruder, after passing through the spinneret to form filaments, cool them with a cooler, suck in air from the lower part of the conveyor belt to extend, and form the first spunbond mesh layer on the continuously moving platform conveyor belt and a second spunbond web layer. Melt-blown polypropylene with a melt index (MFR) of 1000 g / 10 min. Blue masterbatch was used as in the spunbond layer. Melt and mix the main raw material and the masterbatch sheet in the extruder, spin through a porous spinneret, and extend the polymer, and the extended polymer forms a melt-blown network layer according to 1-5 μm fine lines. The third melt-blown net layer is a two-layer structure,...

Embodiment 2

[0079] Except the overall weight of non-woven fabric is 60g / m 2 , The temperature of the hot air dryer is the same as in Example 1 except that it is 145°C. Conditions and physical properties are shown in Table 2 and Table 3.

Abstract

The invention relates to a preparation method of medical polypropylene multi-layer non-woven cloth, which comprises the following steps: a first spun-bonded overlay, a second spun-bonded overlay and a third melt-blown overlay are formed to form a spun-bonded / melt-blown / spun-bonded overlay; the three overlays are thermally bonded by a glazing machine to be endowed with stable shape; the non-woven cloth endowed with stable shape is soaked into the solution mixed with oil resistance agent and antistatic agent and dried, receives heat treatment, and is endowed with water resistance, oil resistance and antistatic properties. The polypropylene multi-layer non-woven cloth improves the permeability effect of water resistance agent, oil resistance agent and antistatic agent, is very economic, has no harm to the human body and environment pollution, no fire, explosion and other danger when being stored and used.

Description

technical field [0001] The invention relates to a medical polypropylene multilayer non-woven fabric and a manufacturing method thereof. More specifically, it relates to bio-barrier non-woven composite materials such as surgical gowns, sterile cloths, and surgical cloths for surgical patients that can be used in the medical field, and is made of ultrafine fiber high-density filter cloth materials. It has the effect of blocking microorganisms, excellent water resistance, oil resistance and alcohol resistance, and completely isolates blood and body fluids. It has excellent anti-static and air permeability and good wearing feeling, so that the medical team can perform operations under hygienic and comfortable conditions, and prevent infection in hospitals. Polypropylene multilayer nonwoven fabric for medical use and its manufacturing method. Background technique [0002] Generally, bio-barrier non-woven fabrics inhibit the penetration of bacteria and other pollution sources, an...
