Problems solved by technology

The disadvantages of this production method are: (1) due to the use of multi-component adhesives in the production process, the follow-up process requires a relatively complicated procedure to remove the residual chemical substances on the bandage, which complicates the production process; (2) the elasticity Too large, which affects blood circulation; (3) The surface is too hard and rough, which makes the skin uncomfortable; (4) Some adhesive residues on the skin surface need to be cleaned

Embodiment 1

[0029] The fiber self-adhesive elastic bandage of the present invention is prepared according to the following steps:

[0030] (1) Raw material preparation: select PP fiber (Hubei Botao Synthetic Fiber Co., Ltd., specification 2.5d / 5.0mm), after the feeding system has been metered, enter the cotton blending machine for blending, and process fibers of various lengths and deniers Fully mixed, the mixed raw materials are taken out by the feet and sent to the next process by the fan;

[0031] (2) Carding: make the fibers form a uniform fiber web; using a carding machine, use various types of rotating card clothing and different card clothing rotation speeds and directions to fully card the fibers, remove impurities, and achieve parallel straightening In the state of single fiber, the fibers are fully mixed, and finally a uniform fiber network is formed.

[0032] (3) Cross-lapping: use a cross-lapping machine (cross-lapping device) to spread the fiber web reciprocally and evenly, ...

Embodiment 2

[0038] The fiber self-adhesive elastic bandage of the present invention is prepared according to the following steps:

[0039] (1) Raw material preparation: select PET fiber with low melting point (Hubei Yizheng Chemical Fiber Co., Ltd., specification 20d / 3F), enter the cotton blending machine after metering in the feeding system for blending, and fully mix fibers of various lengths and deniers , the mixed raw materials are taken out by the feet and sent to the next process through the fan;

[0040] (2) Carding: make the fibers form a uniform fiber web; using a carding machine, use various types of rotating card clothing and different card clothing rotation speeds and directions to fully card the fibers, remove impurities, and achieve parallel straightening In the state of single fiber, the fibers are fully mixed, and finally a uniform fiber network is formed.

[0041](3) Cross-lapping: use a cross-lapping machine (cross-lapping device) to spread the fiber web reciprocally an...

Abstract

The invention discloses a method for manufacturing a fiber self-adhesion elastic bandage, which comprises the process flows of: processing by a charging system; metering; mixing cotton; hackling; laying a net; processing by a primary forming system; punching a hole; processing by a secondary forming system; forming a semi-finished product; splitting and packaging; and forming a finished product. The method has a simple process. No chemical substances are added in the manufacturing process, and thus, no chemical substances are left in the product.

Description

technical field [0001] The invention relates to a method for making a fiber self-adhesive bandage, in particular to a method for making a self-adhesive bandage using single-component fibers. Background technique [0002] In medical work, such as limb sprains, soft tissue injuries, joint swelling and pain, etc., elastic bandages are commonly used for auxiliary treatment, but they need to be buckled with buckles at the end of bandaging, and cannot be sticky with the bag, so it is inconvenient to use. [0003] Chinese patent CN200410041232.8 discloses a self-adhesive bandage and its production method. It is formed by coating an adhesive on the base cloth of the bandage. The adhesive formula includes: 80 parts of natural latex; polyalkylene sulfonic acid sodium salt or / and 0.07-0.13 parts of sodium sulfonate; 7-13 parts of glacial acetic acid. The preparation method includes the processes of material preparation, dip coating, curing, washing, drying and the like. [0004] Chin...
