Four primary structures are the base structures from which all weft knitted fabrics are derived. They are: Jersey (or plain) ▪ Rib ▪ Purl, and ▪ Interlock. Each is composed of a different combination of face and reverse meshed stitches, which are knitted using a particular combination of needles.
What are the basic structures of weft knitting?
Four primary base weft knitted structures–plain, rib, interlock and purl–are the base structures from which all weft knitted fabrics and garments are derived. Each is composed of a different combination of face and reverse meshed stitches, knitted on a particular arrangement of needle beds.
What are three basic stitches in weft knitting?
The basic stitches in weft knitting are face loops, reverse loops, float stitches and tuck stitches. Transferring stitches to adjacent needles creates openwork effects (Tables 1.7 and 1.8). Single jersey fabrics are knitted on one bed of needles which means that the loops are all intermeshed in the same direction.
What are the characteristic of the basic type of weft knits?
- Slowest of the knitting machines.
- Both side similar appearance.
- More expensive.
- Good stretch in all direction.
- Stretches out of shape easily.
- Crosswise stretch less than a jersey knit.
- Thicker than jersey knits.
- Does not curl.
What are the basic elements of knitting?
There are 3 Basic Knitting elements. They are: Needle. Sinker.
Function of sinker: The functions of sinker are given below:
- Loop formation.
- Holding down.
- Knocking over.
What is weft knitted?
Definition of weft knit
: a knit fabric produced in machine or hand knitting with the yarns running crosswise or in a circle — compare warp knit.
What are the 2 types of weft knitting machines?
12.4 Types of weft knitting machines
The weft knitting industry can be divided into three manufacturing sectors: fully fashioned, flat V- bed knitting and circular knitting. The most important difference among the various types of weft knitting machines is in the number of needle beds and the number of needles used.
What is the difference between warp knitting and weft 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.
How do you identify weft knit fabric?
If the threads appear to have loops, then it’s knit; if the threads have a perpendicular criss-cross pattern, it’s woven. Check for stretch. Knit fabrics will have much more stretch than woven fabrics.
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).
What is the most common weft knit?
Among all types of weft knit fabrics, the single jersey fabric is most popular.
- Half cardigan,
- Milano rib,
- French pique,
- Swiss pique.
How do you identify a knitted structure?
Usually looks same on fabric’s face and reverse, making it reversible. Fancy double knits may have novelty stitch on fabric’s face and fine ribs on reverse. Properties: Heavy, firm; usually has almost no stretch in either direction. Good shape retention; cut edges don’t curl.
Which stitch structure is wider than the normal knit structures?
Knit fabric structure and machine parameter has profound influence on the fabric width. The structure with tuck stitches is wider than the normal knit structures. The loop shape at the tuck stitch is distorted and has a wider base as the side wales are not pulled together .
What is the function of weft knitting sinker?
On bearded needle weft knitting machines of the straight bar frame and sinker-wheel type (as on Lee’s hand frame), the main purpose of a sinker is to sink or kink the newly laid yarn into a loop (Figure) as its forward edge or catch (C) advances between the two adjacent needles.
How many types of cam are used in weft knitting?
Knitting cam are three types;
Knit Cam. Tuck Cam. Miss Cam.
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.
