Description

[Detailed description of the invention] [Field of industrial application] The present invention aims to promote the healing of wounds, bruises, etc. of humans or animals by covering the diseased area with gauze, absorbent pads, etc.
Cover it indirectly over the drug-containing patch, etc., or
By directly covering the treated material,
It relates to an elastic bandage used to minimize bleeding, relieve pain, prevent bacterial infection from the outside, or prevent irritation.

[Conventional technology]

Conventional elastic bandages are made by using covered yarns (rubber or spandex filaments in a stretched state and wrapping them around other spun yarns or filaments) as warp yarns, elastic yarns as core yarns, or elastic yarns as the core yarns, on a plain loom. Using threads such as cotton, soft cloth, and polyester,
The weft is made of cotton, cotton, polyester, etc., with 38 to 45 threads/inch in the warp direction and 60 to 90 threads/inch in the transverse direction.
A plain weave type elastic bandage woven to a density of Latssel knitting in which covered yarn elastic yarn is inserted in a zigzag pattern within 3 wale skips without looping cotton, cotton, polyester yarn, etc. in the horizontal direction with the third reed, 12 to 16 wales/12 to 16 wales/ Ratchet type elastic bandages knitted at a density of 80 to 90 courses/inch in the course direction are known.

The former plain weave type elastic bandage is unhygienic as the cut surface easily frays and lint falls off, the tissue easily deforms and the winding is not aesthetically pleasing, and only the elastic threads become loose and the elasticity is reduced. It had the disadvantage of being lacking.

The latter type of elastic bandage, like the plain weave type, tends to fray at the cut end, causing lint to fall off, making it unhygienic, and causing only the elastic threads to come loose, resulting in deformation near the cut end. However, there were disadvantages such as a lack of elasticity, an uneven surface that did not feel good on the skin, and a disadvantage that the bandages did not fit together well and could shift during use.

In terms of production, both the plain weave and latussel knit types had low production quantities per hour, which placed constraints on price.

[The problem that the idea aims to solve]

This invention does not cause tissue collapse at the cut surface, is hygienic, does not cause tissue deformation, does not cause the elastic thread to come out, has stable elasticity to the end of the bandage, and has elastic properties of the bandage. The purpose of this invention is to provide an elastic bandage with a desired surface finish and high productivity.

[Means to solve the problem]

This purpose, according to the present invention, uses elastic yarns and processed yarns in the warp direction in warp knitting, at least the elastic yarns are knitted in loops in units of two courses in the warp direction with zero jumps in the wale direction, and the third yarn This is achieved by repeatedly knitting in a zigzag pattern in units of two courses, with three or more wales skipped, without looping in each wale direction.

It is preferable that the textured yarn is looped in a zigzag pattern from the opposite direction to the elastic yarn in units of two courses or more in the warp direction with zero skips in the wale direction.

The textured yarn can also be looped in parallel to the elastic yarn from the same direction in two or more course units in the warp direction with zero skips in the wale direction.

Furthermore, the processed yarn can also be inserted into a chain-like structure knitted with elastic yarns without looping in the warp direction at zero intervals in the wale direction.

As the third yarn, an inelastic yarn or a textured yarn can be used.

[Effect]

In this invention, the elastic yarn is looped in units of two courses in a chain-like structure in the wale direction that controls elasticity in the warp direction. Since the third thread inserted in the wale direction is also looped for each course of the elastic thread, there is no possibility of thread slippage or loss of stitches. Also, because the third thread or three or more wales are inserted in the horizontal direction, the bandage has a uniform surface and curls and shrinkage in the width direction are prevented.

The elastic properties can be adjusted by selecting the method of knitting the processed yarn.

Furthermore, by choosing an inelastic yarn as the third yarn, it is possible to create a relatively thin bandage, and by choosing a processed yarn, it is possible to create an elastic bandage that is relatively sublime, soft to the touch, and slightly stretchable in the width direction. It will be done.

Although nine examples have been shown above, the present invention is not limited to these, and various structures can be used by combining or modifying them.

[Effect of idea]

According to the present invention, the elastic yarn is looped in units of two courses in the warp direction from the first reed in the wale direction 0, and even when the elastic bandage is stretched, the elements that stretch are only in the chain direction and in the wale direction. Since the elastic threads are not connected to adjacent chains, it has the advantage of being able to be used on the affected area with a stable width without narrowing the width.Also, since the elastic threads are looped in two-course units, each The elastic thread forms a knot in each loop, and even if it is stretched or cut midway, the elastic thread does not come off, providing stable stretchability. In addition, it has become possible to provide a hygienic elastic bandage that does not deform the tissue and has a stable opening, has a beautiful finish, is resistant to fraying at the cut end, and has less lint coming off.

Since elastic yarn and textured yarn are used in the warp direction, by selecting the knitting method of the textured yarn, it is possible to freely change the elongation rate and back stretch characteristics, which differs only from the modulus value of the elastic yarn. It became.

When an inelastic thread is used as the third thread, fixing force can be obtained in the width direction with a relatively thin fabric, making it effective as an elastic bandage in the orthopedic field that requires fixation. In this case, it has become possible to obtain an elastic bandage that can be slightly stretched in the width direction and has favorable characteristics as a bandage for use on joints, etc.

By inserting the third yarn without looping with a jump of 3 or more wales, there is no unevenness due to looping in the width direction compared to high-density looping in the warp direction, and the number of repeated zigzag bends is small, resulting in a smooth surface. A smooth elastic bandage is obtained.

Furthermore, elastic thread is looped in each course,
Since knots are created and the elastic threads do not fall out, elastic bandages can be made with only urethane elastic threads or rubber elastic threads (bare yarn), making it possible to make elastic bandages with thin materials. There is no need to use expensive elastic yarns that have been processed, and since a tricot knitting machine is used, which can knit at much higher speeds than plain looms or ratchet knitting machines, economical and highly productive elastic bandages can be obtained. It is something.
