Embodiment 1

[0017] Using different colors of cotton false-twist low-torque yarns as raw materials, the twist coefficient is 230-270, after loosening tube → dyeing yarn → drying → tightening tube → weaving → bleaching and dyeing → finishing steps to process colored striped jersey.

[0018] The weaving process adopts single jersey weft jersey on a single jersey circular knitting machine. The threading method is 1-32F through white cotton low-torque yarn, 33-48F through black cotton low-torque yarn, weaving density 300mm / 100 needles, the yarn tension is 10-12g.

[0019] The loom adopts German Meyer MV4-3.2Ⅱ single jersey circular knitting machine, the machine size is 24 needles / 25.4mm, the cylinder diameter is 30", the total number of needles is 2256, and the number of routes is 96F.

[0020] After weaving, the fabric is dyed, washed, and stented at low temperature.

Embodiment 2

[0022] Color striped jersey under the same weaving condition with ordinary yarn count

[0023] Comparative example 1 and example 2 color striped jersey weft data:

[0024] Such as figure 1 Shown, it is ordinary yarn-dyed color striped jersey with a weft slope of 18% and a large weft slope;

[0025] Such as figure 2 As shown, the low-torque yarn-dyed color striped jersey of the present invention has a weft slope of 8.4%. Compared with a jersey woven with ordinary yarn counts, the weft slope is significantly reduced, which improves the utilization rate of the fabric.

Abstract

The invention discloses a low-bias-weft-skew knitted fabric which is characterized in that all-cotton false-twisting low-torque yarn with different colors is taken as a raw material and processed through the steps of spooling, yarn dyeing, drying, tightening, weaving, bleaching and dyeing, and after-finishing, so that the knitted fabric is formed; according to the weaving process, the fabric is woven on a single-sided round machine by using single-sided weft plain stitches; a threading manner is as follows: a fabric 1-32 F is threaded into all-cotton low-torque yarn in the same color, and a fabric 3-48 F is threaded into all-cotton low-torque yarn in another color; the weaving density is 300 millimeters per 100 stitches, and the yarn tension is 10-12 g; and the woven fabric is dyed, washed with water and subjected to low-temperature tenter setting treatment. According to the low-bias-weft-skew knitted fabric, the weaving process is simple, the operation is easy, and the false-twisting low-torque yarn is taken as the raw material, so that the yarn structure is improved, the torque of the yarn is greatly reduced, and loop skewing caused by the fact that the yarn is untwisted in a weaving and looping process is effectively avoided. Weaving parameters of the weaving process and the tenter setting treatment after weaving are adjusted, so that the bias weft skew of the knitted fabric is reduced further.

Description

Technical field [0001] The invention relates to a knitted fabric, in particular to a low weft diagonal knitted fabric. Background technique [0002] In the processing or setting process of knitted fabrics, the degree of non-perpendicularity between the course and the two sides of the fabric is the weft skew. Knitted cotton single yarn weft flat knit fabrics are caused by the existence of yarn twists and the spiral manner during weaving. Generate weft skew. In order to maintain the beauty of the finished product, in the production of color striped weft flat knitting fabrics, the direction of the bust is often kept in the direction of the bust (horizontal straight, vertical diagonal) when cutting. This operation method will waste a triangular fabric on each side of the fabric, resulting in an increase in production costs. [0003] Among the two factors that produce weft skew, the existence of yarn twist is the dominant factor. At present, the weft deviation is mainly corrected thr...
