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.
