In this Blog, We explain the detailed techniques of two different types which are used in Knitting machines, i.e. weft knitting and warp knitting.

Weft Knitting:

In weft knitting, we form loops in the horizontal direction. While doing weft knitting, we can use different types of stitches. The type of stitch which we use in weft knitting affects both the appearance and the properties of the knitted fabric. The basic stitches which we usually use for weft knitting are plain, rib, jersey, and purl. When we use the plain stitch for weft knitting, then we draw each loop through the other loops present on the same side of the fabric. While using the rib stitch, we draw the loops of the same course to both the sides of the fabric. In rib knitting, there are two sets of needles arranged opposite to each other. We use the same thread for both the sets of the needles. While doing rib knitting the two sets of needles form the web and each needle present in one circle takes up the position between its counterparts present in the other circle. In a 2:2 type of rib knitting, two needles of one set alternate with the two needles of the other set.

The interlock structure is also a variant of the rib form of knitting. For getting the interlock structure, we alternately knit the two threads with the opposite needles. When we use the purl stitch for weft knitting, then we draw the loops to the opposite sides of the fabric which gives the appearance of the back of a plain stitch fabric to both the sides of the fabric. For knitting the complicated patterns as well as for controlling the individual needle for each course or every two courses, we can attach Jacquard mechanisms to the knitting machines. To form the tuck stitch, we do not discharge the complete loop from some of the needles in each course, and later on, we remove all the loops together which get accumulated on these needles. We make the plaited stitch by feeding the two threads into the same hook. In the plaited stitch one thread shows up on the one side of the fabric whereas the other thread shows up on the opposite side of the fabric. For producing the float stitch, we miss the inter-looping over a series of the needles so that the thread floats smoothly over a few loops in each course.

Warp Knitting:

In warp knitting, we form loops in the vertical direction. There are primarily two types of warp knitting, i.e. raschel warp knitting which we make with latch needles, and tricot warp knitting which we create by using bearded needles.

Raschel Warp Knitting:

For raschel knitting, we generally prefer to use coarser yarns, but recently, knitting staple yarns are also getting preference for this type of warp knitting. In the Raschel machine used for doing raschel warp knitting, the needles move in a ground steel plate, called as the trick plate. The top of the trick plate which we call the verge defines the level of the completed loops present on the needle shank. The downward pull which the fabric and the sinkers present between the needles creates, makes the needle to rise and prevents the loops from moving upward. The primary role of the guide bars is to feed the yarn to the needles. In a knitting cycle, the needles usually start from the lowest point, where the new loop is going to join the needle hook to the fabric, and the previous loop has just been cast off.

When the new loop opens the latches, then the needles rises and ends up on the shank below the latch. At the same time, the guide bars swing through the needles, and the front bar moves the one needle space sideways. When the guide bar slides back to the front part of the machine, then the front bar lays the thread on the hooks. After that, the needles fall, and the earlier loops close the latch to trap the new loops. Finally, we cast off the old loops. We can make Raschel warp knits in a variety of forms and designs. Raschel warp knitting process is usually more open in construction and is coarser in texture than that of other warp knits.

Tricot Warp Knitting:

For making tricot warp knit we make use of two sets of threads. Tricot warp knitting consists of fine ribs which run vertically on the front part of the fabric and horizontally on its back portion. By using tricot knitting machines, we can make lighter fabrics, weighing less than that of four ounces per square yard. About half of the tricot machines that we are using currently make plain fabrics on two guide bars. At present pattern, knitting is also gaining a lot of popularity. In pattern knitting, while the knitting cycle is going on, we need to keep close control on the motion of the lateral bar which we can achieve by using control chains made up of chunky metal links.
