Definitions

  • the present invention falls in the technical field of textile fabrics, and in particular, in a super-elastic arbitrarily-cut lace fabric formed by knitting a non-hot-melt material.
  • the knitted lace fabric disclosed in the CN101426971A publication is knitted lace fabric using a hot-melt yarn and a production method thereof. After undergoing a knitting operation, the knitted lace fabric is heated at a temperature lower than a melting temperature of a chain stitch yarn but not lower than a melting temperature of a hot-melt yarn, so that the hot-melt yarn is partially melted. A part of the melted portion is stuck to the chain stitch yarn and inserted into the yarn. As a result, the connected state of each yarn can be maintained, thereby preventing wear of the yarn. In addition, the melt and bonded portion may be formed by means of breaking the hot-melt yarn. Therefore, even if a part of the chain stitch yarn constituting chain stitch texture is segmented, it is possible to prevent the chain stitch texture from being worn away by the stuck portion of the hot-melt yarn.
  • the hot-melt yarns, and heating and cutting processes are required for the foregoing patented lace fabrics to achieve its purpose, which greatly increases the cost, prolongs production processes, increases energy consumption, and imposes a certain impact on the environment, and makes the opening of the fabric subject to certain limitations as well.
  • the technical problem to be solved by the present invention is to provide arbitrarily-cut lace fabric of non-hot-melt material, with 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.
  • the present invention adopts the following technical solutions:
  • 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;
  • 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
  • the openings of the elastic weft opening layer and the warp opening layer are each greater than or equal to 80%.
  • the filament yarn used for the elastic weft opening layer is a 20-140 denier polyamide yarn or polyester yarn.
  • the filament yarn used for the elastic weft opening layer is a 20-140 denier spandex core-spun yarn of non-hot-melt material, where the spandex core-spun yarn is composed of a non-hot-melt spandex yarn covered with a layer of polyamide yarn or polyester yarn.
  • the non-hot-melt spandex yarn used for the warp opening layer has a density of 70-560 denier.
  • the non-hot-melt spandex yarn used for the tight resistance layer has a density of 20-140 denier.
  • the weft insertion structure is a weft insertion structure in a same direction or a weft insertion structure in a reverse direction.
  • a knitting needle density of the lace machine used is 18-32 stitches per inch.
  • 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.
  • the present invention discloses arbitrarily-cut lace fabric of non-hot-melt material, including 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; 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 yarn by means of full-set threading and following a chain stitch structure along the warp knitting direction, is further provided inside the main body.
  • the main body of the fabric is knitted by using two filament bars, two non-hot-melt spandex bars, and multiple pattern bars through a chain stitch and weft insertion structure.
  • both warp and weft openings of the fabric body can be greater than 80%.
  • the filament yarn used for the elastic weft opening layer is a 20-140 denier polyamide yarn or polyester yarn.
  • the filament yarn used for the elastic weft opening layer is a 20-140 denier spandex core-spun yarn of non-hot-melt material, where the spandex core-spun yarn is composed of a non-hot-melt spandex yarn covered with a layer of polyamide yarn or polyester yarn.
  • the non-hot-melt spandex yarn used for the warp opening layer has a density of 70-560 denier.
  • the non-hot-melt spandex yarn used for the tight resistance layer has a density of 20-140 denier.
  • the weft insertion structure is a weft insertion structure in a same direction or a weft insertion structure in a reverse direction.
  • a knitting needle density of the lace machine used is 18-32 stitches per inch.
  • the present invention is specifically as follows: the filament bar 2 as shown in FIG. 1 selects a 20-140 denier polyamide yarn or polyester yarn or another filament as required and following a chain stitch structure.
  • the bar 3 as shown in FIG. 1 uses 20-140 denier common filaments as required for the usage of the fabric to form arbitrarily-cut lace fabric implemented by a non-hot-melt material.
  • a 20-140 denier spandex core-spun yarn of non-hot-melt material further is used, following a weft insertion structure in a same direction or a reverse direction, and a spandex core-spun yarn with both filament and spandex properties is used to provide the fabric with elasticity in the weft direction and increase the weft opening of the fabric, so as to form super-elastic arbitrary-cut lace fabric implemented by a non-hot-melt material.
  • the bar 4 as shown in FIG. 1 selects 70-560 denier non-hot-melt spandex as required for full-set threading and following a weft insertion structure along the warp knitting direction, so as to enhance the warp opening.
  • the bar 1 as shown in FIG. 1 is a spandex bar added on the basis of the three well-known ground bars of the lace machine; 20-140 denier non-hot-melt spandex is used as required for full-set threading and following a chain stitch structure along the warp knitting direction, the stretching characteristics of non-hot-melt spandex and adjustment of yarn tension are used to enhance the tightness of yarns in a binding loop by following a chain stitch structure, and the chain stitch structure not only binds the yarns in the loop, but also increases sliding resistance between the yarns due to chemical compositions and surface morphological characteristics of common spandex, which makes it difficult for a loop of the fabric in the warp direction of knitting to pull off and fall apart, so that they are not prone to falling apart after being cut in the weft direction.
  • elastic yarns or filaments of different denier quantities are selected, as required for the usage of the fabric, by using the pattern bar of the lace machine and following a weft insertion structure or looping structure, to form a layered pattern layer to increase the aesthetics.
  • the advantages of the super-elastic arbitrarily-cut lace fabric implemented by a non-hot-melt material in the present invention are mainly reflected in that on the premise of good warp opening, the weft opening is greater than that of common lace, or the weft opening is greater than warp opening, which enhances the disadvantage of poor weft opening of common lace.
  • the present invention improves the dispensability through structural transformation.
  • the present invention adopts the following methods:
  • Warping machine model Karl Mayer DS 21/30 NC-2, passive yarn feeding. Warping temperature: 23°C Warping humidity: 65%
  • the process parameters are set for the workshop under the foregoing temperature and humidity conditions, and the decision of whether to add oil to the yarn is made according to the actual situation.
  • Warping machine model Karl Mayer DSE-H21/30 NC-2, positive yarn feeding. Warping temperature: 24°C Warping humidity: 78%
  • the process parameters are set for the workshop under the foregoing temperature and humidity conditions.
  • Knitting machine model LRJ 83/1B
  • the threading modes are GB1, GB10, GB92 fully threaded, with JB89&JB90 one in one out, and the pattern bar is threaded according to a pattern need.
  • the yarn used for the fabric spandex core-spun yarn, filament, spandex, elastic yarn.
