Characteristics of Rib fabric

(1)   Rib is produced by two sets of needles being alternately set orated between each other.

(2)   The simplest rib in (1 * 1) rib

(3)   It is now normally knitted with two sets of latch needles and known as double jersey fabric.

(4)   Rib has a vertical cord appearance

(5)   Relaxed 1 x 1 rib is twice as thick and half the width of an equivalent plain fabric.

(6)   1 x 1 rib normally relaxes by 30% compound with its knitting width.

(7)   Rib cannot be unroved from the end knitted first because the sinker loops are securely anchored by the cross meshing between face and reverse loop.

(8)   It is used for loops for socks, cuffs of sleeves, rib bordery for garments.

Characteristics of plain fabric

(1)       Plain is the base structure of ladies hosiery, fully fashioned knitwear and single jersey fabric.

(2)       It also used in ladies suiting known as ‘Jersey lily’

(3)       Its technical face in smooth.

(4)       If the yarn breaks, needle loops successibly unmeshed down a wale and sinker loops unmeshed up a wale, this structural break down in termed laddering.

(5)        Plain structure has a three diversional structure.

(6)       It has maximum covering power potential recovery of 40% in width after stretching.

(7)       It has curling effect.

Warp knitting | Weft knitting

Warp Knitting: In a warp knitted structure each loop in the horizontal direction in mach from different thread and the no. of threads used to produce such a fabric is at least  equal to the number of loop in horizontal now. 

It may be say that in a warp knitted fabric the threads run thoroughly in a vertical direction.

Weft knitting: In a weft knitted structure a horizontal row of loops can be made using one thread and the thread runs in horizontal direction.  

Knitting | classification of knitting |

Knitted fabric defers vastly from woven fabrics. Woven fabric is formed substantially by interlacing of a seems of length wise and cross wise threads. Knitting in its simplest form Consist in forming loops though those previously formed.

Knitting: Knitting is the method of creating fabric by transforming continuous strands of yarn into a series of interlocking loops, each row of such loops hanging from the one immediately preceding it. The basic element of a knit fabric structure is the loop intermeshed with the loop adjacent to it on both sides and above below.  

Classification:

(i)                Warp knitting 

                                     

(ii)             Weft knitting
