Problems solved by technology

However, in this patent, the raw materials of the tape substrate are wood pulp fiber and chemical fiber, and chemical fiber is not easy to degrade
In this method, wood pulp fiber and chemical fiber are mixed and then paper-made. The bonding force of the two fibers is poor. The strength of the base material depends on the paper-making molding and then the surface is glued. The glue layer is located on the surface of the base material, which reduces the comfort. Poor anti-sensitivity, poor environmental protection performance; large difference in vertical and horizontal tearing and tensile strength, large difference in smoothness between the front and back sides, etc., and the manufacturing process is complicated, difficult to operate, the process parameters are not easy to control during the gluing process, and the product stability is poor. , High equipment input cost, resulting in high manufacturing cost of the final product

Embodiment 1

[0028] A high-permeability medical tape base material, including the following components: wood pulp fiber, polyester fiber, low-melting fiber, AKD neutral sizing liquid and wet strength agent. The low-melting fiber is ES low-melting two-component composite fiber and A mixture of two kinds of low-melting PVA fibers; the components are evenly distributed and bonded together through adhesion and melting between the fibers. ES fiber is a two-component skin-core composite fiber. The skin layer has a low melting point and good flexibility, while the core layer has a high melting point and high strength. After heat treatment, part of the skin layer is melted to act as a bond, and the rest remain in the fiber state. At the same time, it has the characteristics of low thermal shrinkage. The fiber is particularly suitable for the production of sanitary materials, warm-keeping fillers, filter materials and other products in the hot air penetration process.

Embodiment 3

[0066] A high-permeability medical tape substrate, including the following components, wood pulp fiber, polyester fiber, low-melting PVA fiber, AKD neutral sizing liquid and wet strength agent, each component is evenly distributed and adhered between the fibers And melt together.

[0067] This component includes the following parts by weight: 50 parts of wood pulp fiber, 40 parts of polyester fiber, and 10 parts of low-melting PVA fiber. Among them, the wood pulp fibers are softwood pulp fibers with a fiber length of 2 to 5 mm. The polyester fiber is selected from the polyester fiber with a fineness of 0.5D~1D and a length of 4~10mm. Low-melting PVA fiber chooses low-melting PVA fiber with fineness 0.5D~1D, length 4~10mm, melting point 70~90℃. PVA fiber has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier, and abrasion resistance.

Abstract

The invention discloses a high-permeable medical adhesive tape base material and a preparation method thereof. The adhesive tape base material comprises wood pulp fibers, polyester fibers, low meltingfibers, AKD neutral sizing liquid and wet strength agent liquid. The preparation method comprises a pulping step, a papermaking step, a drying step and a reeling step. In the pulping step, the AKD neutral sizing liquid and the wet strength agent liquid are added to a pulping pool and uniformly mixed. The high-permeable medical adhesive tape base material is prepared by mixing and pulping treatment of pure plant fibers and synthetic fibers through papermaking of a papermaking machine, and has the advantages of softness and loosening, homogeneous fibers, high air permeability, strong wrinkle resistance, easy-tearing while a product meets strength, uniform gluing and the like. The high-permeable medical adhesive tape base material is directly formed through adhesion between the fibers and melted adhesion without surface gluing reinforcement treatment, simple in processing technology, and low in manufacturing cost, and is a substitute good of a current medical cloth-based base material and a punching PE base material. Along with continuous improvement of human health requirements, a demand gap is large, and market prospect is extremely extensive.

Description

Technical field [0001] The invention belongs to the technical field of medical tape substrates, and particularly relates to a high-permeability medical tape substrate and a preparation method thereof. Background technique [0002] Medical tape base material is the basic material for manufacturing medical tape. The existing medical tape base material has many problems, such as poor air permeability, difficulty to tear, and low skin comfort. During the processing of medical tape Need to carry out perforation treatment, special sawtooth processing on the edge of the substrate, the processing process and production process are more complicated. The main body material of the existing substrate is difficult to degrade and has poor environmental protection. Polyester fiber is hydrophobic and prone to floating and flocculation in water. The higher the ratio, the more serious the situation. [0003] The Chinese patent with application number: CN201610359698.5 discloses a breathable medica...
