Embodiment 1

[0007] Embodiment 1: the preparation method of this medical adhesive tape cotton paper mainly comprises the following steps: 1), with the raw material of following weight ratio, wood pulp 30%, vinylon 30%, water-soluble polyvinyl alcohol fiber 20%, polyester 20%, using a beater for beating: the beating concentration is 2.5-3.0%, the beating amp is 50-60A, and the beating time is 15-20 minutes.

[0008] Water-soluble polyvinyl alcohol fiber (PVA) is a valuable functional differentiation fiber. Water-soluble PVA fiber not only has ideal water-soluble temperature, strength and elongation, but also has good acid resistance, alkali resistance and dry heat resistance, and is tasteless and non-toxic after being dissolved in water. It can be decomposed naturally and does not cause any pollution to the environment. It is a 100% green product.

[0009] Composite man-made fibers are chemical fibers that are "bonded" by two polymers into a monofilament. Due to the different composition ...

Embodiment 2

[0016] Embodiment 2: The difference with Embodiment 1 is: the weight ratio of raw materials is 20% of wood pulp, 30% of vinylon, 40% of water-soluble polyvinyl alcohol fiber, and 10% of polyester.

Embodiment 3

[0017] Embodiment 3: The difference with Embodiment 1 is that: the weight ratio of raw materials is 30% of wood pulp, 20% of vinylon, 30% of water-soluble polyvinyl alcohol fiber, and 20% of polyester.

Abstract

This invention involves one kind of medical adhesive tape tissue paper's preparation method, it is made by the following weight allocated proportion raw material, wood-pulp 20 - 40%, vinylon 20 - 30%, water-soluble textile fiber 20 - 40%, compound artificial fiber 10-20%; Concrete technical process: 1) uses the beater beating: beating density 2.5 - 3.0%, beating ampere 50 ~ 60A, beating time 15 ~ 20 minutes; 2) in slurry-storing pool, adds brightening agent 0.1%, adds the anti- water anti- preparation agent 1.5 ~ 2.0%, run bulge time about 3 hours; 3)use machine on spreads cloth; spreads the cloth medicinal preparation is PVA, spreads the cloth density is 2 ~ 3%; 4) makes drying processing. This invention merits are: use multi-components synthetic fiber and the plant fiber matches copies, enhanced the end product porosity, changed paper archery target flexibility; because uses the longer synthetic fiber, enabled the product intensity also to obtain the enhancement. Uses in thick liquid to make up strong and spreads cloth to make up the strong method, had guaranteed binding force between the textile fiber, has guaranteed the product use intensity.

Description

technical field [0001] The invention relates to the field of wet-laid non-woven fabrics, and mainly relates to a preparation method of medical adhesive tape tissue paper. Background technique [0002] Medical tape and tissue paper is one of the wet-laid non-woven series products, which are used as intermediate materials for medical products in the medical and health industry, replacing non-degradable materials such as gauze cloth or plastic film. As the intermediate carrier of viscose, it needs to have high air permeability, high strength, high toughness, and has the advantages of environmental protection, degradability, and no secondary pollution. Due to the use of chemical fiber as the main raw material, it is difficult to make paper on a general paper machine. Chemical fibers have the characteristics of low density, water repellency and non-fibrillation, which are prone to problems such as fiber flocculation and poor strength. Its successful deve...
