Problems solved by technology

The extensibility of this kind of weft-knitted fabric is an advantage as underwear, but it may become a disadvantage when it is used for other purposes, such as industrial use or resin-based composite material reinforcement, because it has the disadvantage of making the fabric easy to stretch and deform, and its shape It is not stable enough, easy to fall apart, and the number of layers cannot exceed two layers, so it cannot be made thick.

Embodiment 1

[0032] The embodiment of the present invention is that weft and flat coil yarns 1, 2, 4, and 5 adopt 100D polyester low elastic yarn, rib coil yarns 3 and 6 adopt 32 cotton yarns, and weft insertion yarns 4 and 8 adopt 150D polyester low elastic yarn. The dense weft-knitted fabric with less stretching and less loosening is woven on a double-face circular knitting machine with a gauge of 18 needles.

[0033] The embodiment of the present invention weaves according to the following steps:

[0034] Step 1: Knit the first half of the full weave cycle of dense weft-knitted fabric with less stretching and less detachment in knitting path A, such as figure 1 shown.

[0035] First, before the knitting needles 21 on the front needle bed 24 and the knitting needles 22 on the rear needle bed 23 start to withdraw the needles and withdraw the loops, put the weft insertion yarn 4 between the old loops of the knitting needles 21 and 22 ,See figure 2 , image 3 ;

[0036] Then, the knit...

Abstract

The invention discloses a knitting method for anti-stretch and anti-laddering dense and thick weft-knitted fabric. According to the method, the number of pieces of participant yarn in each coil height can reach up to 8, rectilinear yarn section arrangement of floating threads and weft insertion for limiting fabric stretch is achieved, and loose and curve yarn section arrangement of linter coil structures for increasing fabric thicknesses is also achieved. The fabric knitted through the method is dense and thick, little in fabric stretch, good in dimensional stability and anti-laddering.

Description

technical field [0001] The invention relates to a weft-knitted fabric, in particular to a weaving method for a dense weft-knitted fabric with less elongation and less detachment. Background technique [0002] Weft-knitted fabrics have great extensibility. This is because the weft-knitted fabric is formed by loops passing through each other, and the loops are formed by bending yarns in space. When the weft-knitted fabric is subjected to external tension, such as vertical and horizontal stretching, the shape of the loop is prone to change, and the distribution state of the yarn in the loop is easily transferred to each other. The extensibility of this kind of weft-knitted fabric is an advantage as underwear, but it may become a disadvantage when it is used for other purposes, such as industrial use or resin-based composite material reinforcement, because it has the disadvantage of making the fabric easy to stretch and deform, and its shape It is not stable enough, easy to fa...
