Embodiment 1

[0023] (1) 60% coniferous wood pulp is subjected to moderate beating treatment, and the pulp density is increased by 5 O SR, mixed with 38% polyester fiber and 2% water-soluble fiber after treatment, added 0.5% wet strength agent by fiber weight to the mixed fiber; fully stirred. Among them, the proportion of 1.0dtex×3mm polyester fiber is 28%, and the proportion of 1.5dtex×12mm polyester fiber is 10%.

[0024] (2) The mixed fibers are made by inclined wire paper machine, and strengthened by surface sizing. The surface glue is a mixture of 2% PVA (polyvinyl alcohol) and 1% AKD, and the coating amount is 1 g / ㎡, coiled into finished products after drying.

[0025] The indicators of breathable medical tape base material are as follows:

[0026]

Embodiment 2

[0028] (1) 60% coniferous wood pulp is subjected to moderate beating treatment, and the pulp density is increased by 5 O SR, mixed with 38% polyester fiber and 2% water-soluble fiber after treatment, added 0.5% wet strength agent and 1% AKD to the mixed fiber; fully stirred. Among them, the proportion of 1.0dtex×3mm polyester fiber is 33%, and that of 1.5dtex×12mm polyester fiber is 5%.

[0029] (2) The mixed fibers are made by a cylinder paper machine, and the surface sizing is carried out to strengthen the treatment. The surface glue is a mixture of 2% PVA (polyvinyl alcohol) and 1% AKD, and the coating amount is 1.5g / ㎡, coiled into finished products after drying.

[0030] The difference from Example 1 is that the rotary screen is used instead of the inclined screen for copying. Appropriately increase the proportion of polyester staple fiber.

[0031] The indicators of breathable medical tape base material are as follows:

[0032]

Embodiment 3

[0034] The difference from Example 1 is that (1) 65% softwood pulp is subjected to moderate beating treatment, and the degree of pulp is increased by 4 O SR, mixed with 33% polyester fiber and 2% water-soluble fiber after treatment, added 0.5% wet strength agent to the mixed fiber; fully stirred. Among them, the proportion of 1.5dtex×3mm polyester fiber is 26%, and 1.5dtex×12mm polyester fiber accounts for 7%.

[0035] (2) The mixed fibers are made by a cylinder paper machine, and the surface sizing is carried out to strengthen the treatment. The surface glue is a mixture of 2% PVA (polyvinyl alcohol) and 1% AKD, and the coating amount is 1.0g / ㎡, coiled into finished products after drying.

[0036] The indicators of breathable medical tape base material are as follows:

Abstract

The invention relates to the field of base materials of medical supplies, in particular to a breathable medical adhesive tape base material and a manufacturing method thereof. The manufacturing method of the breathable medical adhesive tape base material comprises the following steps: (1) carrying out mild pulping treatment on wood pulp fibers, increasing degree of beating by 2-8 degrees of SR, mixing the wood pulp fibers with polyester fibers and water-soluble fibers, and adding a wet strength agent in mixed fibers; (2) manufacturing paper by using the mixed fibers through a cylinder paper machine or an inclined wire machine, carrying out enhancement through surface sizing, and drying and reeling to obtain finished products, wherein the mass percents of the wood pulp fibers, the polyester fibers and the water-soluble fibers respectively account for 50-75%, 20-45% and 1-5% of the mass percent of fibers in breathable medical adhesive tape paper, and the sum of the mass percents of the various components is 100%. A manufacturing process of the method is simple, and the prepared medical adhesive tape base material has the characteristics of high strength, good flexibility, high bulk, high breathability, good evenness and easiness in tearing.

Description

technical field [0001] The invention relates to the field of medical product base materials, in particular to a breathable medical adhesive tape base material and a manufacturing method thereof. Background technique [0002] There are many problems with the base material of existing medical tapes. The base material has poor air permeability and is difficult to tear. During the processing of medical tapes, holes need to be processed, and special sawtooth processing is performed on the edges of the base material. The processing 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] Chinese invention patent application (application number CN200810060243.9 application date 2008.03.31) discloses non-woven wallpaper base paper, including fi...
