What is warp knitting process?

Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric; i.e., following adjacent columns, or wales, of knitting, rather than a single row, or course. For comparison, knitting across the width of the fabric is called weft knitting.

What is the difference between weft and warp knitting?

Warp knitting represents the fastest method of producing fabric from yarns. This differs from weft knitting in that each needle loops its own thread and runs vertically down the fabric. Warp knit fabrics will have the knit stitch on the face of the fabric but have a horizontal zigzag pattern on the back.

What is the characteristic of warp knit?

In comparison with weft-knit structures, warp knits are typically run resistant and are closer, flatter, and less elastic. Two of the most common warp-knit fabrics are tricot and raschel illustrated in Fig. 10.9.

What are the examples of warp knitting?

The two types of warp knitting are raschel, made with latch needles, and tricot, using bearded needles.

Can warp knitting be done by hand?

Warp knitting requires the use of a machine, it cannot be done by hand. Warp knitting is generally used for knitting fibres such as Aramid, Carbon and glass as it puts less pressure on them and uses more careful handling than weft knitting.

Which knitting is faster weft or warp?

Warp knitting represents the fastest method of producing fabric from yarns. Warp knitting differs from weft knitting in that each needle loops its own thread. … Fabric is produced in sheet or flat form using one or more sets of warp yarns.

Which is stronger warp or weft?

Warps yarns are stronger compared to weft yarns. During the weaving warps are held under high tension, moves up and down for shed formation. Warp yarns are finer than weft yarns.

What is tuck stitch?

A tuck stitch is formed when a needle already holding a loop, receives a further loop (Fig. 3.6). This second loop is tucked in behind the held stitch. Fabrics with tuck loops have reduced length elasticity but increased width as the tuck loops pull down the held loops and cause them to spread (Fig. 3.7).

Why is chain link necessary for warp knitting?

Chain link:

The pins pass through all the tracks and chains, and the ends fit into grooves in the serrated flanges of the pattern drum so that as the drum turns, the chain links are advanced in unison in correct timing relationship.

What is overlap and Underlap in knitting?

This part of the structure is called an overlap. The second part is the length of yarn connecting each formed loop with the next succeeding loop, which is called an underlap, shown in green. It is formed by the shogging or lateral movements of the yarn ends across the back side of the needles.

What is knitting cycle?

Knock over position ( loop forming) – the needle is lowered still further and old loop slides over the trapped new yarn inside the hook, forming a new loop by completing the knitting cycle. Knitting cycle is completed with the new loop in the hook of the needle.

Is mesh a warp knit?

The warp-knitted mesh fabrics have the advantages of light weight, high strength and designable mesh. At the same time, with the increasing proportion of warp-knitted mesh fabric in the field of industrial textiles, the performance and application research of warp-knitted mesh fabric is increasing gradually as well.

Is interlock a weft or warp knit?

In warp knitting, each thread has its needle and the fabric is knitted in the lengthwise direction (vertically). Weft knitted fabrics are made of one thread interlocked horizontally.

What is warp knitting machines?

Warp knitting machines are either single needle bar machines or double needlebar machines and are available in a wide range of gauges and widths, Modern machines are electronically controlled in terms of patterning, beam let-off and fabric take-up.
