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-melt fiber, AKD neutral sizing solution and wet strength agent, the low-melt fiber is ES low-melt two-component composite fiber and A mixture of two types of low-melt PVA fibers; each component is evenly distributed and bonded together by bonding and melting between fibers. ES fiber is a composite fiber with a two-component sheath-core structure. The cortex has a low melting point and good flexibility, while the core has a high melting point and high strength. After heat treatment, a part of the cortex melts and acts as a bond, while the rest remains in the fiber state. At the same time, it has the characteristics of small thermal shrinkage rate. The fiber is especially suitable for the production of hygienic materials, thermal insulation fillers, filter materials and other products by the hot air penetration process.

[0029] The components include...

Embodiment 3

[0066] A high-permeability medical tape base material, including the following components, wood pulp fiber, polyester fiber, low-melt PVA fiber, AKD neutral sizing solution and wet strength agent, each component is evenly distributed and bonded through the fibers and melt together.

[0067] The components include the following parts by weight: 50 parts of wood pulp fiber, 40 parts of polyester fiber and 10 parts of low-melt PVA fiber. Wherein the wood pulp fiber selects coniferous wood pulp fiber with a fiber length of 2 to 5 mm. The polyester fiber is selected from polyester fibers with a fineness of 0.5D to 1D and a length of 4 to 10mm. The low-melt PVA fiber is selected from low-melt PVA fibers with a fineness of 0.5D-1D, a length of 4-10mm, and a melting point of 70-90°C. PVA fiber has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier, and abrasion resistance.

[0068] Such as figure 1 As shown, a ...

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 base materials, in particular to a high-transparency medical tape base material and a preparation method thereof. Background technique [0002] The base material of medical tape is the basic material for making medical tape. There are many problems in the existing base material of medical tape, such as poor air permeability, difficult to tear, and low skin comfort. During the processing of medical tape Drilling is required, and special sawtooth processing is performed on the edge of the base material, and the processing and production process is relatively complicated. The main material of the existing base material is difficult to degrade and has poor environmental protection. Polyester fibers are hydrophobic, and are prone to floating and flocculation in water. The higher the ratio, the more serious the situation. [0003] The Chinese patent with the application number CN201610359698.5 di...
