Method for manufacturing double needle bed imitation tie-dyed fabric and fabric

Abstract

This invention relates to the field of warp knitting technology, specifically to a method for manufacturing a double-needle bed tie-dye fabric and the fabric itself. The fabric is woven using a double-needle bed warp knitting system with seven guide bars. Guide bars GB1 and GB2 use a full-thread method to form loops in the front needle bed yarn, creating a plain weave surface layer. Guide bars GB3 and GB4 use a one-through-one-open-thread method to form loops in the front and back needle bed yarns, creating patterns on the surface and bottom layers. Guide bar GB5 uses a full-thread method to form loops in the front and back needle bed yarns, creating an intermediate elastic interlayer. Guide bars GB6 and GB7 use a full-thread method to insert a third yarn, forming loops in the back needle bed yarn to create the plain weave bottom layer of the fabric. The tie-dye fabric proposed in this invention shortens the subsequent dyeing and printing processes, greatly improving production efficiency. By using various specifications and colors of space-dyed yarns in conjunction with warp knitting technology, it provides a tie-dye effect similar to the chaotic and disordered style of conventional warp knitting tie-dye, yet possessing its own unique knitting patterns.

Description

Technical Field

[0001] This invention relates to the field of warp knitting technology, specifically to a method for producing a double-needle bed imitation tie-dye fabric and the fabric itself. Background Technology

[0002] Tie-dyeing is a traditional Chinese intangible cultural heritage technique. Its products have a unique Chinese artistic style and have become increasingly popular in the market in recent years.

[0003] However, traditional tie-dyeing techniques are basically limited to natural fibers such as cotton, linen, and silk, making it difficult to achieve good dyeing results on synthetic fibers such as polyester.

[0004] Polyester is one of the main materials for warp-knitted shoe uppers. Therefore, it is difficult to achieve the tie-dye effect directly on warp-knitted shoe uppers using traditional tie-dye techniques.

[0005] Currently, the process for achieving tie-dye effects in existing warp-knitted tie-dyed fabrics is typically as follows: yarn warping → weaving → greige fabric single-stitching → single-stitched fabric dyeing → finished product printing.

[0006] The process is lengthy, and the screen printing technology used has limitations in pattern design and weak expressiveness of tie-dye style. While digital printing technology offers more flexible patterns, it is more expensive.

[0007] Therefore, how to achieve an effect with an authentic tie-dye style efficiently and at low cost on warp-knitted polyester shoe uppers has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention proposes a warp-knitted double-needle bed imitation tie-dye fabric. The material is polyester and polyester space-dyed yarn. Various specifications of space-dyed yarn are combined with warp knitting process design to form the imitation tie-dye fabric.

[0009] Variegated yarn is a type of textile that uses a special dyeing process to create two or more different color zones on a single yarn or piece of fabric.

[0010] To achieve the desired tie-dye effect, a single specification of space-dyed yarn can be dyed in several different colors as needed.

[0011] A method for producing a double-needle bed imitation tie-dye fabric, wherein the double-needle bed fabric includes a face layer, a back layer, an intermediate elastic spacer layer located between the face layer and the back layer, and a pattern located between the face layer and the back layer, and the method includes the following steps: (1) Knitting preparation: Design the pattern of the fabric and its machine operation process on the warp knitting CAD computer software; (2) Comb configuration of warp knitting machine: On a warp knitting machine with 7 combs and double needle bed, the combs are arranged in the following order from front needle bed to back needle bed: combs GB1, GB2, GB3, GB4, GB5, GB6 and GB7. (3) On-machine weaving: Among the 7 guide bars, guide bars GB1 and GB2 are fully threaded. The first yarn is threaded through the yarn in the full threading method to form the surface layer of the fabric, and the yarn is looped in the front needle bed to form a plain weave surface layer; guide bars GB3 and GB4 are threaded through the space-dyed yarn in the one-through-one-open threading method to form a loop in the front and back needle bed and to form a pattern on the surface and bottom layers; guide bar GB5 is threaded through the second yarn in the full threading method to form a loop in the front and back needle bed and to form an intermediate elastic interlayer; guide bars GB6 and GB7 are threaded through the third yarn in the full threading method to form a loop in the back needle bed and to form the plain weave bottom layer of the fabric.

[0012] Furthermore, GB1 guide bar fully inserts the first yarn, forming loops in the front needle mattress yarn, and knits a 1-0-1-1 / 1-2-1-1 / / warp plain weave; GB2 guide bar fully inserts the first yarn, forming loops in the front needle mattress yarn, and knits a 1-2-1-1 / 1-0-1-1 / / warp plain weave; guide bars GB3 and GB4 insert space-dyed yarn alternately, forming loops in the front and rear needle mattress yarns, with guide bar GB3 knitting a 1-0-0-0 / 0-1-1-1 / / weave, and guide bar GB4 knitting a 1-0-1-0 / 0-1-0-0 / 1 -0-0-0 / 0-1-0-1 / 1-1-1-1 / 1-1-1-1 / / weave, forming a pattern; the guide bar GB5 is fully threaded through the second yarn, forming loops in the front and back needle mattress yarns, weaving 1-0-2-3 / 4-5-3-2 / / to form an intermediate elastic interlayer; the guide bars GB6 and GB7 are fully threaded through the third yarn, forming loops in the back needle mattress yarn, GB6 weaves 0-0-0-1 / 2-2-2-1 / / warp plain weave, GB7 weaves 2-2-2-3 / 1-1-1-0 / / warp pile weave, forming a plain weave base.

[0013] Furthermore, the fineness of the third yarn is greater than that of the first yarn.

[0014] Furthermore, the first yarn is one of polyester semi-dull yarn, bright yarn, or matte yarn.

[0015] Furthermore, the second yarn is a polyester monofilament.

[0016] Furthermore, the third yarn is a low-elastic polyester yarn.

[0017] Furthermore, the first yarn is one of nylon semi-dull yarn, bright yarn, or matte yarn.

[0018] Furthermore, the space-dyed yarn includes at least three colors.

[0019] Furthermore, double-needle bed fabrics are used for shoe uppers.

[0020] A fabric made by the method described above.

[0021] Compared with the prior art, the beneficial effects of the present invention are reflected in: The warp-knitted double-needle bed tie-dye fabric proposed in this invention shortens the subsequent dyeing and printing process, greatly improving production efficiency. By using various specifications and colors of space-dyed yarns in conjunction with warp knitting technology, it provides a tie-dye effect that is similar to the chaotic and disordered style of conventional warp-knitted tie-dye, yet has its own knitting regularity. This enables the production of tie-dye style products for synthetic fiber shoe uppers. Attached Figure Description

[0023] The technical solution of the present invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0024] Example 1 This embodiment proposes a method for manufacturing a double-needle bed imitation tie-dye fabric. The double-needle bed fabric includes a face layer, a back layer, an intermediate elastic spacer layer between the face layer and the back layer, and a pattern located between the face layer and the back layer. The padding yarn pattern is shown below. Figure 1 As shown, its manufacturing method includes the following steps: (1) Knitting preparation: Design the pattern of the fabric and its machine operation process on the warp knitting CAD computer software; (2) Comb configuration of warp knitting machine: On a warp knitting machine with 7 combs and double needle bed, the combs are arranged in the following order from front needle bed to back needle bed: combs GB1, GB2, GB3, GB4, GB5, GB6 and GB7. (3) On-machine weaving: Among the 7 guide bars, guide bars GB1 and GB2 are fully threaded. The first yarn is threaded through the yarn in the full threading method to form the surface layer of the fabric, and the yarn is looped in the front needle bed to form a plain weave surface layer; guide bars GB3 and GB4 are threaded through the space-dyed yarn in the one-through-one-open threading method to form a loop in the front and back needle bed and to form a pattern on the surface and bottom layers; guide bar GB5 is threaded through the second yarn in the full threading method to form a loop in the front and back needle bed and to form an intermediate elastic interlayer; guide bars GB6 and GB7 are threaded through the third yarn in the full threading method to form a loop in the back needle bed and to form the plain weave bottom layer of the fabric.

[0025] Furthermore, GB1 guide bar fully inserts the first yarn, forming loops in the front needle mattress yarn, and knits a 1-0-1-1 / 1-2-1-1 / / warp plain weave; GB2 guide bar fully inserts the first yarn, forming loops in the front needle mattress yarn, and knits a 1-2-1-1 / 1-0-1-1 / / warp plain weave; guide bars GB3 and GB4 insert space-dyed yarn alternately, forming loops in the front and rear needle mattress yarns, with guide bar GB3 knitting a 1-0-0-0 / 0-1-1-1 / / weave, and guide bar GB4 knitting a 1-0-1-0 / 0-1-0-0 / 1-0-0-0 / 0- The 1-0-1 / 1-1-1-1 / 1-1-1-1 / / weave uses a double-sided looping process to form tie-dye patterns on the surface and bottom layers; the GB5 guide bar is fully threaded with the second yarn, forming loops on the front and back needle mattress yarns, and weaving 1-0-2-3 / 4-5-3-2 / / to form an intermediate elastic interlayer; the GB6 and GB7 guide bars are fully threaded with the third yarn, forming loops on the back needle mattress yarn, GB6 weaves 0-0-0-1 / 2-2-2-1 / / warp plain weave, and GB7 weaves 2-2-2-3 / 1-1-1-0 / / warp pile weave to form a plain weave base.

[0026] The first yarn is 75D semi-dull polyester yarn, the second yarn is 30D monofilament, the third yarn is 150D low-elastic polyester yarn, and the space-dyed yarn is either blue and white two-color space-dyed yarn or cyan, blue and white three-color space-dyed yarn.

[0027] When the space-dyed yarn is dyed in two colors (white and another color), it creates a single-color tie-dye effect; when the space-dyed yarn is dyed in three colors (white and two other colors), it creates a two-color tie-dye effect.

[0028] In addition, variegated yarn can also be multi-colored variegated yarn with white and other colors, or multi-colored variegated yarn without white, to create a multi-colored tie-dye effect.
