Definitions

  • the present invention relates to a double-sided fabric, and particularly to a double-sided fabric stacked with a continuous cord material and forming a thickness in a woven sack interlayer.
  • the embedding process of the continuous cord material to be embedded is performed by yarn stitching operations using knitting needles.
  • the continuous cord material may not be reliably stitched by the knitting needle in the yarn stitching process, hence easily resulting in an unsatisfactory fabric. That is to say, when adopting the above technology for embedding the continuous cord material, the length of the continuous cord material cannot exceed 1 inch.
  • the development of fabrics manufactured from the above weaving technology also suffers from severe restrictions.
  • the flat bed knitting machine described refers to a model that includes a front needle bed and a back needle bed. During a weaving process, such flat bed knitting machine is capable of manufacturing not only a single-sided fabric by independently using one of the needle beds but also a double-sided fabric by simultaneously using the front and back needle beds that weave alternately.
  • Taiwan Utility Model Patent No. M317443 "The Textile with Three Different Thickness Fibers".
  • the above disclosure discloses a three-fiber fabric having different thicknesses including an upper fabric layer, a low fabric layer and a hard yarn thick layer.
  • the lower fabric layer is partially tightened and connected to the upper fabric layer to be spaced to form a thin layer region.
  • the hard yarn thick layer is a formed integral, and is spaced and disposed between the upper fabric layer and the lower fabric layer, and is adjacent to the thin layer region. Because the hard yarn thick layer is capable of supporting the upper fabric layer and the lower fabric layer, a certain thickness can be maintained.
  • the primary object of the three-fiber fabric with different thicknesses is forming a fabric evenly distributed with different thicknesses and shapes by directly weaving the three fibers, so as to save processing time and manpower and thus reducing production costs.
  • the primary object of the three-fiber fabric woven by the above disclosure is weaving the fibers into a fabric evenly distributed with different thicknesses and shapes. That is to say, the fabric of the above disclosure does not provide a technical solution that allows setting the number of times of stacks at a predetermined position according to a required thickness as desired.
  • the three-fiber fabric of the above disclosure does not satisfy market needs. Therefore, there is a need for a solution that overcomes drawbacks and limitations of the above disclosure.
  • the present invention causes the continuous cord material to stack and form a thickness in the woven sack interlayer, so as to weave a double-sided fabric appearing relief embossed and having different thicknesses.
  • the doubled-sided fabric stacked with the continuous cord material and forming a thickness in the woven sack interlayer according to the present invention not only effectively satisfies consumer market needs, but also reduces manpower and time costs as well as effectively enhancing production efficiency.
  • the present invention provides a double-sided fabric stacked with a continuous cord material and forming a thickness in a woven sack interlayer.
  • the double-side fabric is woven from a face yarn by a flat bed knitting machine, which includes a front needle bed, a back needle bed, and a loop presser bed.
  • the front needle bed includes a plurality of front knitting needles.
  • the back needle beds includes a plurality of back knitting needles at corresponding positions staggered from the front knitting needles.
  • the loop presser bed is above the front needle bed or the back needle bed, and includes a plurality of right-directed weaving pressing pieces and left-directed weaving pressing pieces alternately arranged in gaps of the plurality of front knitting needles and the plurality of back knitting needles, respectively.
  • the double-sided fabric further includes a woven sack interlayer formed from loops stitched from the face yarn by the plurality of front knitting needles and the plurality of back knitting needles.
  • the woven sack interlayer includes therein at least one continuous cord material, which is pressed into the woven sack interlayer by the plurality of right-directed weaving pressing pieces and the plurality of left-directed weaving pressing pieces to become folded and stacked to form a thickness.
  • the continuous cord material is guided and fed in from the front needle bed towards the double-sided fabric, and guided towards the front needle bed to depart the double-sided fabric.
  • the continuous cord material is guided and fed in from the front needle bed towards the double-sided fabric, and guided towards the back needle bed to depart the double-sided fabric.
  • the continuous cord material is guided and fed in from the back needle bed towards the double-sided fabric, and guided towards the back needle bed to depart the double-sided fabric.
  • the continuous cord material is guided and fed in from the back needle bed towards the double-sided fabric, and guided towards the front needle bed to depart the double-sided fabric.
  • the thread diameter of the continuous cord material is greater than the thread diameter of the face yarn.
  • the present invention achieves following effects compared to the prior art.
  • the continuous cord material is stacked in the woven sack interlayer of the double-sided fabric, such that the double-sided fabric may offer preferred thickness and piling effect.
  • the continuous cord material may be stacked in the woven sack interlayer according to an operator setting and form a required thickness, so as to manufacture a double-sided fabric appearing relief embossed and having different thicknesses for effectively satisfying consumer market needs.
  • a post procedure of adding a filler material can be eliminated to reliably reduce manpower and time costs and effectively enhance production efficiency.

  • the front needle bed includes a plurality of front knitting needles.
  • the back needle bed includes a plurality of back knitting needles at corresponding positions staggered from the front knitting needles.
