Technical Field

The invention relates to a glass fiber warp-knitted medical bandage, and belongs to the field of medical textiles.

Background

Bandages are one of the common devices in medicine, used for protection and fixation at wounds or after surgery. The traditional plaster bandage has long curing time and poor air permeability, is not beneficial to wound recovery, is inconvenient for doctors to operate and review after operation, and is almost replaced by medical polymer bandages. The medical high molecular bandage in the market at present is mainly prepared from polyester fiber and glass fiber as raw materials by a resin coating or heat treatment method. The bandage is light, thin, comfortable, waterproof and short in curing time, and brings better use feeling for doctors and patients.

Wherein the base material has a significant effect on the overall performance of the bandage. The glass fiber has high strength and is transparent to X-rays, but the glass fiber yarn has high rigidity and no elasticity, and the glass fiber base cloth with certain extensibility can be formed by weaving. Although many methods for weaving glass fiber base fabrics have been developed, they often fail to achieve desired effects in practical use, such as dimensional instability, low elasticity, susceptibility to wrinkles, and the like. The invention adopts the warp knitting mode to process the glass fiber yarn, the process is simple, the production efficiency is high, and the performance of the glass fiber warp knitting fabric is more suitable for being used as a macromolecular bandage. Differences in surface coating resins also affect the performance of the bandage, not only are the curing times different, but the overall comfort of the bandage also changes.

Disclosure of Invention

In order to solve the problems, the invention provides a glass fiber warp-knitted medical bandage, which adopts warp knitting to manufacture glass fiber base cloth, improves the performance of the glass fiber fabric as bandage base cloth, and has the advantages of light weight, softness, good extensibility and rebound resilience, stable size, proper mesh size, capability of meeting the air permeability requirement, suitability for coating materials such as resin and the like. The fabric is coated with a resin to cure rapidly in a short time after it encounters light or some substance in the air.

The invention is realized by the following technical scheme:

a medical bandage made of glass fiber warp knitting comprises a bandage, wherein the bandage is made by knitting and processing through a warp knitting machine, a knitted chain or a variable knitted chain is adopted for the bandage, a fabric with meshes is formed by adding a weft insertion tissue, a variable warp flat tissue and a satin tissue, the surface of the fabric is coated with resin, and the fabric is made of glass fiber.

In a further improvement, the glass fiber yarn is an untwisted roving.

The further improvement is that the glass fiber roving is formed by bundling glass fiber short fibers.

The bandage is further improved in that the bandage comprises a warp knitting structure, the warp knitting structure is formed by weaving a plurality of guide bars, the front comb moves in a chain knitting mode, and the rear comb moves in a weft insertion mode.

In a further improvement, the warp knitted structure comprises a pillar stitch, the pillar stitch being an open pillar stitch as a ground stitch.

The further improvement is that the weft insertion structure is two to six-stitch needle back lapping yarn, and the chaining formed by the front comb is connected into a whole piece.

The further improvement is that the weaving chain and the weft insertion organization reverse lapping yarn form a plurality of fabric interweaving points.

In a further improvement, the fabric has a mesh opening size of no more than two millimeters in a natural state.

The further improvement is that the resin is natural light curing resin or ultraviolet light curing resin, and the bandage is cured without soaking water when in use.

Compared with the prior art, the invention has the following advantages and positive effects:

the glass fiber has better X-ray transmittance than polyester fiber, which is convenient for the later examination of medical treatment. Glass fiber-based fabrics are generally stronger than those made from synthetic organic fiber fabrics, scrims, nonwovens, and other non-glass fiber composite fabrics. The fabric is prepared by a warp knitting method, so that the resilience of the fabric is increased, and the human body fitting performance and the dimensional stability are superior to those of woven or non-woven fabrics. The mesh size is moderate, which is beneficial to bearing coating substances. And the coated ultraviolet light curing resin layer also increases the strength of the bandage to a certain extent, the bandage does not need water when in use, the infection probability is reduced, the discomfort of the skin can not be caused, and the curing time can be adjusted through the difference of the irradiation light time.
