[0017] (2) Preparation of elastic tearable non-woven fabric:

[0018] The preparation method of the tearable non-woven fabric is as follows: take 98 parts by weight of polypropylene slices produced by Jinshan Petrochemical Company as Y37007, add 2 parts by weight of brown color masterbatch slices, and add a small amount of antioxidant 1010 and light stabilizer UV-327, mixed evenly, is sucked into the screw extruder by the vacuum feeding system, and the temperature is controlled between 225.235~C, and the polymer is melted and extruded, and the melt is filtered by a filter, metered by a metering pump, and then passed through a spinneret Spray into filaments, the temperature of spinneret spinning is controlled between 200-300~C, and the spinning speed is controlled between 3000.4500m / min. Then, the ejected silk is introduced into the air duct, blown and cooled by side blowing, and the blowing speed is set between 0.8-1.6m / s. After the cooled filaments are drafted by the draftin...

Abstract

The invention relates to a lacerable non-woven fabric adhesive elastic bandage. The bandage is made of an elastic lacerable non-woven fabric and an adhesive, wherein the elastic lacerable non-woven fabric is selected from elastic chemical fiber lacerable non-woven fabrics; and the adhesive comprises the following components in part by weight: 1-100 parts of sanitary synthetic adhesive, 0-100 parts of sanitary hot -melt pressure sensitive adhesive, 0-100 parts of solvent oil, 0.01-3 parts of environment-friendly additive, 1-2 parts of coloring agent, 0.001-2 parts of anti-aging agent and 0-50 parts of filling agent. Because the cross lapping technology is adopted during the manufacturing process of the used non-woven fabric, the non-woven fabric is lacerable. After the non-woven fabric is made into the bandage, the bandage can be easily lacerated crosswise, the fracture surface is flat, and a great use convenience is brought for medical care personnel and related personnel.

Description

technical field [0001] The invention relates to a bandage, in particular to a tearable non-woven sticky elastic bandage. Background technique [0002] Non-woven fabrics are widely used as sanitary cloths, bandages and industrial geotextiles. Among them, the non-woven fabric produced by spunbond method with polypropylene as the main raw material has the characteristics of low melting point, good tensile tension, good fatigue resistance, mildew resistance, anticorrosion and antibacterial, etc., and is widely used in the medical bandage industry. But the polypropylene non-woven fabric of prior art is owing to adopt parallel laying net or claim parallel type laying net in its production process, the non-woven fabric that makes to produce can't be torn. When used as a bandage, it is difficult to tear it from the horizontal direction, or after it is broken by force, its section is also very irregular, and the user often has to cut it with scissors, which is very inconvenient to u...
