Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has appropriate flexibility, elasticity and restoring force, and
This invention relates to a waist lining for inside belts and the like that has excellent shape retention, uniform adhesion of anti-slip resin, no fear of falling off, and high productivity.

Conventionally, inside belts have generally been woven from ordinary textile threads such as cotton yarn, or made from thick non-woven fabrics. When washed, they often break and do not restore their shape, or lose their shape-retaining properties, resulting in unsightly curling and unsightly defects.

For this reason, an improved method is commercially available in which synthetic monofilament yarn is inserted into the weft of a wide woven fabric and heat-cut in the longitudinal direction as required.

However, although this inside belt prevents it from turning outward due to the restoring force of the synthetic monofilament yarn, it has poor elasticity, and the glue falls off when attention is paid to it and when washed, loosening the bond between the warp and weft yarns, and causing the synthetic monofilament yarn to loosen. Since the yarn skin is smooth, the monofilament yarn slides freely and comes out of the fabric, resulting in sharp cut edges that can sting the wearer's skin, causing discomfort.

Moreover, in the above-mentioned inside belt, when synthetic filaments are used for the warp yarns, the synthetic filament yarns used also have smooth threads, so they tend to slide and cause slippage, so the warp yarns are packed tightly together. There is an uneconomical need to use useless thread and to prevent sliding.

In addition, with these conventional inside belts, adhesion resin powder is sprinkled on the fabric surface to prevent slippage, and the adhesive resin powder is heat-treated and crimped to ensure sufficient adhesion to the fabric surface. In addition to the risk of falling off, it is also difficult to uniformly spread the powder over the entire surface of the belt, which, combined with the complexity of the loading process, poses a commercial disadvantage.

The present invention improves the above-mentioned drawbacks, and provides a waist lining made of a knitted fabric that has appropriate flexibility, longitudinal elasticity, and resilience, as well as excellent shape retention and a remarkable effect on preventing belts from turning outward. The purpose is to provide

Furthermore, in the present invention, there is no need to worry about the adhesive resin falling off, and the adhesion of the resin to the inside belt etc. is complete and uniform due to knitting, and it is possible in the process of knitting the inside belt etc. The object is to provide a commercially advantageous waist lining that does not require an attachment process.

A further object of the present invention is to efficiently produce the above-mentioned improved knitted waist lining, reduce production costs, and provide high-performance waist linings such as inside belts at low cost.

Another object of the present invention is to impart further elasticity to the above-mentioned waist lining and to improve the fit of slacks, skirts, etc. using knit fabrics.

The features of the waist lining of the present invention that achieve the various objectives of the present invention, such as diagonal tops, are as follows: First, on one side of the flexible synthetic monofilament yarn layer with strong elasticity, which is swung to the full width of the required thin width , a multifilament yarn cross-cutting layer in which a synthetic multifilament yarn having a higher heat shrinkability than the monofilament yarn is swung horizontally from each wale to wells that are more than one wale away from each other, and an overlapping portion of each swung yarn is formed between the wales. The structure has the potential to create a curved shape with the multifilament horizontally carved layer as the inner surface through heat processing, by arranging both layers and fixing them with warp stitches for each wale. The second method is based on the above-mentioned structure, with a multifilament yarn cross-cut layer on the back side, and low-temperature welding yarns with a relatively lower melting point than monofilament yarns and multifilament yarns on the front surface, which are distributed between adjacent wales for each wale. When bonded to the belt cloth, the multifilament yarn shrinks when heated with an iron or the like, forming a convex shape on the surface side and exhibiting a curved shape, and the welding yarn has the potential to be melted and used as an adhesive. There is a particular thing.

The third feature of the present invention is that, in addition to the second structure, stretchable threads are further arranged in the vertical direction to impart stretchability in the vertical direction.

5. Waist lining mainly refers to the inside belt of pants and skirts, and also refers to fabrics used on the waist lining of pants, skirts, etc. to give tension to the core and maintain the shape.

Hereinafter, specific details of the waist lining of the present invention will be explained based on embodiments shown in the accompanying drawings.

Fig. 1 Main vehicle Fig. 3 shows the basic structure of the first invention of the present invention. Reference numeral 1 indicates a flexible synthetic monofilament yarn with strong elasticity that forms the base layer, such as a warp yarn. Using a knitting machine, the cloth is swung to the required width to form ears at both ends, and then knitted back and forth, forming a narrow base layer with a continuous bent shape.

Reference numeral 2 is a synthetic multifilament yarn in which the synthetic monofilament yarn 1 is swung horizontally from each well by more than one wale on one side of a layer of a required width to form overlapping portions 2' of each waving yarn between the wales. As with the monofilament yarn layer, it is swung between wales using a warp knitting machine to form a weft layer on one surface of the monofilament yarn layer.

This synthetic fiber multifilament yarn 2 is a yarn with higher heat shrinkability than the monofilament yarn 1. Specifically, the synthetic fiber monofilament yarn 1 is a monofilament yarn with a relatively high melting point and strong elasticity, such as nylon or polyester fiber. On the other hand, there are nylon, polyester fibers, acrylic fibers, etc. manufactured with different heat shrinkability.

The thickness of each of the above-mentioned fiber yarns 1 and 2 is selected from time to time depending on the purpose, place of use, etc., but the synthetic monofilament yarn 1 has a thickness after 800 denier #J. This is the most common method, and a single warp knitting machine can simultaneously form up to 45 monofilament yarn layers with a full knitting width per hour.

4 is a stitch consisting of a warp stitch, such as a chain stitch, in which a horizontal layer of multifilament yarn 2 is layered on one side of a synthetic monofilament yarn layer, and the monofilament yarn 1 and multifilament yarn 2 are horizontally layered. At the same time, another knitting yarn is knitted together.

This stitch 4 may be replaced with a normal tricot stitch or the like.

Both ends of the required knitting width of the synthetic monofilament yarn 1 form a continuous U-shaped bend to form ears, and the yarns for knitting the stitches 4 are knitted together by knitting needles, or the synthetic fiber multifilament yarn 2 By knitting, each course is stopped and the stitches are prevented from slipping.

FIG. 3 shows a synthetic fiber multifilament yarn layer in the width direction obtained by heat-processing the waist lining fabric of the required knitting width consisting of the synthetic monofilament yarn layer, the synthetic multifilament yarn layer, and the warp stitches obtained as described above. The synthetic fiber multifilament yarn 2 has a higher heat shrinkage rate than the monofilament yarn, and is therefore curved with the layer of the synthetic fiber multifilament yarn 2 as the inner surface.

Here, the above-mentioned curved shape occurs because the synthetic monofilament yarn 1 and the synthetic multifilament yarn 2 are knitted together in the wale direction by the stitch yarn, so when the synthetic fiber multifilament exhibits large heat shrinkability due to heating, the synthetic fiber multifilament yarn 2 becomes shorter than the synthetic monofilament 1 between the lateral swing widths, and becomes like a bow string in comparison to the synthetic monofilament 1 between the lateral swing wales.

At this time, since the synthetic fiber monofilament yarn 1 has strong elasticity and flexibility, the synthetic fiber multifilament yarn 2
It is stretched by heat shrinkage and is curved in its entirety with the layer of synthetic multifilament yarn 2 as the inner surface with respect to a plane including both side edge portions.

It goes without saying that the formation of a curved shape due to such a difference in heat shrinkage has a mechanically stronger restoring force than a conventional straight shape, and therefore the effect of preventing the belt from turning over becomes remarkable.

4 and 5 illustrate the second feature of the present invention, in which the base layer is a yarn layer made of the same synthetic monofilament yarn 1 as in the first invention, and the back side thereof is heat-shrinkable as described above. Shake the synthetic fiber multifilament yarn 2 with high elasticity horizontally from each wale to the wales that are more than one wale jump apart.
Layering the overlapping portion 2' of each swinging thread between the wales,
On the opposite side, that is, on the surface, a layer is arranged in which low-temperature welding yarn 3 having a relatively lower melting point than the monofilament yarn 1 and multifilament yarn 2 is distributed between adjacent wales in each wale.

The synthetic monofilament yarn layer, the synthetic multifilament yarn layer, and the low-temperature welding yarn 3 layer are then knitted together by the warp stitches 4 as in the first invention.

The low-temperature welding yarn 3 is, for example, a copolymer fiber yarn of polyethylene and vinyl acetate, or a fiber yarn with strong welding properties such as nylon 12 60.
It is a fiber with a melting point of .degree. C. to 80.degree. C., and it melts during subsequent thermal processing, such as heating with an iron, and plays the role of an adhesive.

m×, this welding thread 3 can also form a rough surface on the cloth surface to have a non-slip role.

The heat-treated waist lining shown in FIGS. 4 and 5 has a convex shape on the surface side due to the shrinkage of the highly contractible yarns, exhibiting a curved warped shape, thereby strengthening the restoring force.

In addition, during the heat processing in this case, the surface on which the low-temperature welding yarn is shaken should not be brought into contact with the heating roll surface.

6 and 7 are examples of the waist lining according to the third aspect of the present invention, and furthermore, the waist lining according to the second invention, that is, the waist lining having the configuration shown in FIGS. 4 and 5. Elastic threads 5 are arranged and inserted in the longitudinal direction on the back side between the synthetic monofilament yarn 1 and the synthetic multifilament yarn 2 of the lining and are knitted together.

By inserting the elastic yarn 5, this waist lining has strong elasticity in the vertical direction, that is, in the longitudinal direction, and provides a good fit for slacks and skirts that have an elastic belt.

Of course, if a non-stretchable thread is inserted and knitted in place of the stretchable thread 5, a strong non-stretchable belt can be obtained.

As the elastic thread 5, polyurethane elastic thread is most preferable, and rubber thread, synthetic fiber processed thread, etc. can also be used.

The waist lining of the present invention has the above-mentioned configurations,
In its use, as shown in FIG. 8, for example, the inside belt A according to the present invention is thermally bonded to the outer fabric 6 of the belt using a hot roller press or the like.

In Fig. 8, 7 indicates the main body cloth of the slacks,
8 indicates the cloth.

During thermal bonding, since the second and third waist linings of the present invention are curved in a convex manner on the front side due to contraction of the highly heat-shrinkable yarn, outward curling of the belt is further prevented.

Here, outward bending usually refers to the fact that when the inside belt bends along with the body toward the front side of the body due to forward bending of the body, if the belt does not have elasticity to restore itself, it will remain bent at the waist, and the present invention This can be prevented because the synthetic monofilament that is the main material of the waist lining has elasticity.

Moreover, when heated, the synthetic fiber multifilament shrinks and becomes a curved shape with the synthetic fiber monofilament side as the surface and the central part protruding from the plane including the edges on both sides. The force due to the arcuate tension is added to the belt, which becomes even stronger and prevents the belt from turning over more effectively.

Note that the above-mentioned curved shape utilizes the inherent shrinkage of the thread, and the effect lasts semi-permanently.

It is also possible to use it in place of the cloth 8 shown in FIG. 8, and the effect of its curved shape can be exhibited.

As described above, the present invention is constructed by forming each layer by swinging synthetic fiber monofilament yarn and cross-cutting synthetic fiber multifilament with large heat shrinkage, and fixing by warp stitching. It has elasticity and has a better fit than a waist lining made of woven fabric, and the elasticity of the synthetic multifilament provides excellent resilience against bending, preventing it from turning up.
Due to the presence of multifilament with high heat shrinkage, it has the potential to warp the waist lining simply by heating it afterwards, and therefore it can be used to create trousers,
When applied to the waist of slacks, heating causes the pants and slacks to warp at the same time as they fit to the waist, resulting in a remarkable effect of strengthening the light part and further improving the prevention of curling up.

In addition to the above-mentioned effects, the second invention in which low-temperature welding yarn is knitted has the advantage that it is not attached to the waist lining by knitting, unlike conventional adhesive resin powder sprayed and crimped by heat processing. It is perfect, so there is no worry of it falling off, making it easy to handle, and it has the feature of being uniform over the entire surface of the back of the waist, and it is possible to achieve even adhesion by heat processing. It has the advantage that a special step of resin adhesion can be omitted since it is formed at the same time.

In addition, in the third invention, an elastic yarn is inserted into the waist lining and knitted, in addition to the elasticity of the knitted fabric itself, the elastic yarn adds elasticity, making it possible to easily create a highly elastic waist lining. and,
It can be easily obtained and has a remarkable effect of further improving the fit.

All of the above-mentioned waist linings of the present invention can be knitted in dozens of rows at a time with one warp knitting machine due to their structure, which improves productivity and reduces production costs. It has the advantage that the lining can be provided at a very low cost.

Furthermore, the synthetic monofilament yarn that makes up the base layer has elasticity, giving the belt appropriate flexibility and shape retention.Although the synthetic monofilament yarn is swung over the entire knitting width, it has appropriate elasticity, so both ends It is knitted continuously with a rounded U-shaped bend at both ends by folding the selvedges, and synthetic monofilament yarn is woven into a wide fabric as a weft, and the synthetic monofilament yarn is cut in the middle of the width. The edges of the synthetic monofilament are exposed and sharp, and there is no need to worry about them sliding through the grain of the fabric and pricking your skin. They are woven together and fastened to ensure the effect of preventing stitches from slipping.

Thus, as described above, the waist lining of the present invention has various superior effects compared to conventional waist linings, and is a novel, highly practical, and innovative waist lining.
