Arbitrarily-cut lace fabric of non-hot-melt material

Abstract

Arbitrarily-cut lace fabric of non-hot-melt material includes a fabric body knitted on a lace machine. The fabric body has a main body knitted by using two filament bars and two spandex bars. A pattern layer, formed by knitting an elastic yarn or filament following a weft insertion structure or a looping structure using a pattern bar, is provided on the main body, and an elastic weft opening layer, a warp opening layer and a tight resistance layer are further provided inside the main body. The present invention has the advantages of good tensile properties in the warp and weft directions, which can be stretched freely in all directions and is not prone to falling apart after being cut, and can be widely used in underwear, corsets. sports, and leisure clothing.

What is claimed is: 
     
         1 . Arbitrarily-cut lace fabric of non-hot-melt material, comprising a fabric body knitted on a lace machine, characterized in that the fabric body has a main body knitted by using two filament bars and two spandex bars, and a pattern layer, formed by knitting an elastic yarn or filament following a weft insertion structure or a looping structure using a pattern bar, is provided on the main body;
 an elastic weft opening layer, configured to provide weft elasticity and increase weft opening and obtained by using one of the filament bars to knit a filament yarn following a weft insertion structure, is provided inside the main body;   a warp opening layer, configured to increase warp opening and obtained by using one of the spandex bars to knit a non-hot-melt spandex yarn by means of full-set threading and following a weft insertion structure along the warp knitting direction, is further provided inside the main body; and   a tight resistance layer, configured to increase tightness of yarns and sliding resistance between yarns and obtained by using the other spandex bar to knit a non-hot-melt spandex yam by means of full-set threading and following a chain stitch structure along the warp knitting direction, is further provided inside the main body.   
     
     
         2 . The arbitrarily-cut lace fabric of non-hot-melt material according to  claim 1 , characterized in that openings of the elastic weft opening layer and the warp opening layer are each greater than or equal to  80 %. 
     
     
         2 . arbitrarily-cut lace fabric of non-hot-melt material according to  claim 2 , characterized in that the filament yarn used for the elastic weft opening layer is a 20-140 denier polyamide yarn or polyester yarn. 
     
     
         4 . The arbitrarily-cut lace fabric of non-hot-melt material according to  claim 2 , characterized in that the filament yarn used for the elastic weft opening layer is a 20-140 denier spandex core-spun yarn of non-hot-melt material, wherein the spandex core-spun yarn is composed of a non-hot-melt spandex yarn covered with a layer of polyamide yarn or polyester yarn. 
     
     
         5 . The arbitrarily-cut lace fabric of non-hot-melt material according to  claim 4 , characterized in that the non-hot-melt spandex yarn used for the warp opening layer has a density of 70-560 denier. 
     
     
         6 . The arbitrarily-cut lace fabric of non-hot-melt material according to  claim 5 , characterized in that the non-hot-melt spandex yarn used for the tight resistance layer has a density of 20-140 denier. 
     
     
         7 . The arbitrarily-cut lace fabric of non-hot-melt material according to  claim 6 , characterized in that the weft insertion structure is a weft insertion structure in a same direction or a weft insertion structure in a reverse direction, 
     
     
         8 . The arbitrarily-cut lace fabric of non-hot-melt material according to  claim 6 , characterized in that a knitting needle density of the lace machine used is 18-32 stitches per inch.
