Novel Fabric Made of All Elastomeric Fiber and Its Applications

Abstract

The present invention relates to a knitted fabric which adopts a novel weaving principle of changing knitting material structure to realize functions and effects which can not be achieved by ordinary fabric. The knitted fabric comprises the main component of novel woven 100 percent spandex fabric made of 100 percent spandex filament. Presently, elastic rubber pieces, rubber bands, etc., are applied to the underwear at the market for enhancing the elasticity and supporting effect. The common features is that they all have a poor elastic resilience, unstable structure, and prone to distortion and raveling. The present novel knitted fabric changes the principle of crocheting of the ordinary material of the traditional knitted fabric, adopting 100 percent spandex filament as the main material to change the elastic resilience, force, and structure stability of the traditional knitted fabric. The mutual double pulling effect of the knitted fabric in the spandex filament after crocheting is to remedy the defaults of the fabric of which the structure is deformed and the elastic resilience and the force are weakened after the fabric is elongated. Compared with the original fabric, the elastic recovery and the elastic force of the fabric are greatly increased and improved.The weaving process and the features of the novel 100 percent spandex fabric are as follows:(1) Warp yarn and weft yarn which are made of 100% spandex filament material are mutually crocheted.(2) The back weft of the spandex filament is required to pass through a filament packaging frame and a weft yarn accelerating conveyer device is provided.(3) Curling is required to be avoided. The specification of the spandex filament of which the warp yarn used required to be considered, so is the specification and constituents of the back weft made of the spandex filament.The preset novel 100% spandex fabric can completely replace the elastic woven band and rubber piece in the prior underwear to play a role of enhancing the elasticity and strength. It can also completely replace the prior common elastic woven band and rubber piece, providing good hand feel, flatness, smoothness, close fit, sound elastic resilience, comfort wear, etc. It can be widely applied to garment industry, particularly to the underwear, such as brassiere, swimwear, briefs, etc.A strap having a memory function, comprising yarns of substantially 100% spandex. The rubber band and ordinary strap applicable in the present market provide a poor elastic resilience, which would easily deform. The said strap having a memory function weaved with warp yarn made of 100% spandex and weft yarn made of 100% spandex, whose structure could be not only plain weave, but also twill or tracery. The fabric has the “memory” function by which it returns to substantially its original shape after being stretched many times it original size. It can provide excellent hand feel, good flatness, smoothness, close fit, sound elasticity, and comfortable wear when used to replace the existing ordinary elastic rubber bands. It can be widely applied in the garment industry, especially in the field of underwear such as brassiere, swimwear, briefs, lingerie, etc.The present patent for utility model discloses a laminable elastic fabric whose main components are 100% spandex elastic woven band and warp knitted shell fabric or weft knitted cloth, and the elastic fabric is formed through laminating processing. The laminated fabric currently used on the market does not have good elastic resilience and is thus easily deformed and is relatively thick. The new laminated elastic fabric of the present patent is relatively light and thin, and the elastic woven band is formed by interweaving 100% spandex warp threads and 100% spandex weft threads, and the elastic fabric is formed by laminating it to the inner side of the shell fabric. The fabric has a recovery of nearly 100% after many times of use. The fabric laminated with said woven band has the characteristics of excellent hand feel, good levelness, softness and smoothness, close fit, good elasticity, comfortable wear, etc. Meanwhile, the processing is simple, and mechanical automation and mass production can be realized, which complies with the efficiency of market economy.

Description

FIELD OF THE INVENTIONThe 100% spandex fabric relates to the field of textile, specifically to elastic woven band and underwear, particularly to top-grade elastic fabric, top-grade underwear and other products made of the fabric.BACKGROUND OF THE INVENTIONPresently, it is known that elastic materials are used for the upper and lower bundles (i.e. flanks) of bras in order to assist the cups in supporting the breasts and keeping them in position relative to the chest circumference, which is also used for the waists of panties to increase elasticity. In the present market, elastic strap and elastic rubber pieces are mainly used with two methods. One is to enclose them in cloth through flat seams. The other is to directly attach them to cloth. However, the conventional elastic strap have poor elastic resilience and will easily have elastic creep and lose elasticity after being used several times. The elastic strap will cause uneven pressure in some parts regardless whether they are encl...

AI Technical Summary

Benefits of technology

1. The novel 100% spandex fabric has sound elastic resilience to increase the elasticity and strengthen the support for underwear, which particularly can be applied in woman's shoulder strap, meeting the requirements on smoothness, close fit, sound elasticity, high level of wearing comfort, flatness, solid, etc.

3. The technical scheme of the novel 100% spandex fabric is as follows: the fabric's main feature is that 100 percent spandex filament is crocheted to be the main material. As spandex is the fiber with the best elasticity and elongation property out of all of the chemical fibers available, the breaking point of stretching can reach 500 to 800 percent of its original length, the elastic recovery rate can reach more than 95 percent, and the spandex can provide good tenacity, small area and good flexibility. The fabric which takes the 100% spandex filament as the main material can achieve the requirements which can not be achieved by other elastic fabric in the aspects of shape, appearance and practicability. The novel 100% spandex fabric has good elastic resilience, fecundity, durability, softness and thinness, which can replace prior conventional rubber products, and provide flatness, soft hand feel, sound resilience and comfort wear, etc. The present novel 100% spandex fabric can be widely applied to the field of underwear, such as brassiere, shoulder straps, swimwear, briefs, etc.

The present novel knitted fabric changes the crocheting principle of ordinary material of traditional knitted fabric, adopting 100% spandex filament as the main material to change the elastic resilience, the force and the structure stability of knitted fabric. The mutual double pulling effect of the knitted fabric in the spandex filament after crocheting to remedy the defaults of the fabric that the structure is deformed and the elastic resilience and the force are weakened after the fabric is elongated. Compared with the traditional woven band, which the warp yarn and weft yarn are mainly made of elastic nylon with a 1.2 to 1.5 times elastic recovery rate, the warp yarn and weft yarn made of spandex can have a 5 to 8 times elastic recovery, thus would be easily found that the elastic recovery and force of the present 100% spandex fabric would be greatly increased and improved because its warp yarn and weft yarn are both made of spandex yarn.

Problems solved by technology

Since the laminated woven band currently used on the market is required to be relatively thin, it will easily rip or burst weftwise under external force and is difficult to return to its original shape after the external force is released.
