- 2. What is Knitting? Knitting is a method by which thread or yarn may be turned into cloth or other fine crafts by inter looping. Knitted fabric consists of consecutive loops, called stitches. It can be done using machine or by hand.
- 3. • Warp knit fabrics are constructed with yarn loops formed in a vertical or warp direction. WARP KNITTING • Weft knits are constructed from one yarn that is fed into knitting machine needles in a horizontal direction. Also called filling. WEFT KNITTING TYPES OF KNITTING
- 4. Weft knitting Single Jersey Purl stitch Rib stitch Interlock stitch Warp Knitting Tricot Knits Raschel Knits Milanese Stitch- bonding
- 5. WEFT KNITTING •Weft or filling knits is the most common type used to produce textile knitted products. •Weft knits are constructed from one yarn which is fed into a knitting machine in a horizontal direction. • weft knit may be knitted with multiple yarns to produce interesting pattern design. •Both flat bed and circular knitting machines can be used to make weft knit. • Few types or technique used to manufacture weft knit structure are Single jersey, Purl, interlock and Rib.
- 6. SINGLE JERSEY STITCH •Jersey knits have flat vertical lines on the front and dominant horizontal ribs on the back of the fabric. •Plain jersey fabric is the simplest weft knitted structure.
- 7. SINGLE JERSEY STITCH contd… Characteristics •Stretch crosswise and lengthwise, stretches more in the crosswise. •Tend to run or ladder if stitch breaks . •Fabric less stable and curls when cut. End-uses • Used for making sweaters, terry robes, t-shirts, men’s underwear and dresses. • Used form making hosiery and pantyhose. • Also used for making fully fashion garments.
- 8. PURL STITCH •A simple purl fabric looks like the back of jersey knit on the both side of the fabric. •Purl fabrics are made on knitting machines called purl knit machines or links-or- links machines.
- 9. PURL STITCH contd… Characteristics •The production process of purl knit is slow. •Both side similar appearance. •Good stretch in all direction but stretches out of shape easily. •Thicker than jersey knits and does not curl on edges. End uses • Used for making infant and children’s wear. •Used for making sweaters and scarves. •Used for doing fancy garment parts.
- 10. RIB STITCH •Rib fabric is a double jersey knitted fabric with vertical rows (wales) of loops. •Simplest rib fabric is 1 x 1 rib having alternate wales knitted to the front and back. •The ribs tend to close up to create a double faced fabric, which has the same appearance on both sides. •Rib knits fabrics are produced with the knitting machines having two sets of needle, normally positioned at rights angle to each other.
- 11. Characteristics RIB STITCH contd… •Its reversible fabric . • More elastic and more thicker than jersey knits. •More stretch crosswise than length wise and edges do not curl. •More expensive to produce. End-uses •Used for making Collars and cuffs and necklines. • Used for doing bottom edges of sweaters. •Used for making double knits jackets, knit hats and men’s hosiery.
- 12. INTERLOCK STITCH •Interlock stitch knits are variations in rib stitch knits. •Interlock is produce on a cylinder and dial circular weft knitting machine, with alternate long and short needles opposite to each other on cylinder and dial.
- 13. INTERLOCK STITCH contd… Characteristics •It is a reversible fabric. •It is heavier and thicker as compare to rib and it does not curl at the edges. •It is a good insulator. •Costlier fabric . End-uses •Used for making Skirt, blouses and t-shirts. •Used as an outwear fabric for making dresses.
- 14. WARP KNITTING •Warp knitted fabric is produced from a set of warp yarn. It is parallel knitted to each other down the length of the fabric. •More resistant to laddering than weft knits.
- 15. Tricot Knits •The right side of the fabric has fine lengthwise ribs while the reverse has crosswise ribs. •A soft and 'drapey' texture with some lengthwise stretch and almost no crosswise stretch. •Tricot fabric is soft, wrinkle resistant. •Tricot is very common fabric for making lingerie.
- 16. Raschel Knits •Made out of conventional or novelty yarns which allows for interesting textures and designs to be created. •Raschel knits are produced from spun or filament yarns of different weights and types. •It is coarser than other warp knit fabrics. •Used for making lace fabric and trimmings.
- 17. Stitch-Bonding Knits •Stitch-Bonding is a special form of warp knitting and is commonly used for the production of composite materials and technical textiles. •Fabrics produced with this process offer the potential of using “sensitive fiber materials such as glass and carbon with only little damage, non-crimp fiber orientation and variable distance between threads”. •The advantages of includes its high productivity rate and the scope it offers for functional design of textiles, such as fiber-reinforced plastics •Being used in fields as wind energy generation and aviation.
- 18. Milanese Knits •It is made from two sets of yarn knitted diagonally, which results in the face fabric having a fine vertical rib and the reverse having a diagonal structure. •Milanese fabric is superior to tricot in smoothness, elasticity, regularity of structure & friction resistance. •It is stronger, more stable, smoother and more expensive than tricot.
