Texture And Patterning

Question 1

How are double layer knits made?

Answer 1

Each layer knitted on a different needle bed, then can be tied together by knitting on both needle beds.

Question 2

What are double layer knits used for?

Answer 2

• reversible knits
• top layer and lining
• intermittent knits on solid backgrounds

Question 3

What techniques can you use to make double layering more effective?

Answer 3

-different coloured yarns, different fibre types or counts, different textured yarn

Question 4

What kind of machines are double layer knits made on?

Answer 4

-flat machines or circular machines with two needle beds, as long as there is a individual needle selection facility

Question 5

How can varied stitch length be produced?

Answer 5

Advanced machines can vary length from one needle to the next to create texture or opaque areas of knit

Question 6

What is multi-gauging?

Answer 6

MG is a way to vary stitch lengths where two or more stitch length can be used in different parts of a fabric

Question 7

How are knitted lace, cables, and plaited ribs created?

Answer 7

By using stitch transfer

Question 8

A way to create texture is by using fancy and textured yarns. Name three

Answer 8

Slub
Knop
Boucle

Question 9

What is ‘laying-in’? How is it produced?

Answer 9

When a special ‘laying-in’ yarn carrier is used just ahead of the normal yarn carrier, the LI carrier place yarn in between the knit, trapping it in the fabric without actually knitting it in.

Question 10

What are the tree methods of producing pile fabrics on a weft knit?

Answer 10

Sliver knitting
Knitting sinker loops
Knitting and raising floats

Question 11

How is sliver knit produced?

Answer 11

Slivers of fibre are presented to needles as they rise to collect new yarn in the knitting sequence
As the needles go to know-over depth, the yarn produces plain knit stitches and the fibre creates tufts that stick out on the reverse side of the fabric.

Question 12

What type of knit is a sliver knit?

Answer 12

Plain knit

Question 13

What is sliver knitting used for?

Answer 13

• Makes fake fur for coats, toys and furnishings

- Different colours and fibre lengths can be used to create patterns that looks like animal fur

Question 14

What is fake fur usually made from?

Answer 14

Acrylic or modacrylic yarns

Question 15

How does back-coating do to fake fur?

Answer 15

Prevents fibre pile from pulling out during use

Makes fabrics more stiff, rigid and dimensionally stable

Question 16

How are sinker loops made?

Answer 16

Circular single jersey machines have blades between needles that provide tension while knitting normally. On some advanced machines these sinkers can also produce loops of yarn that appear from the reverse side of fabric.

Question 17

What are sinker loops fabrics used for?

Answer 17

Towelling, baby-grows, beach wear, car upholstery etc

Question 18

How many types of sinker loops can some advanced machines make?

Answer 18

Three, no loop, short loop, or long loop. Patterns can be made by mixing loop lengths

Question 19

How can sinker loops become velour fabrics?

Answer 19

By cropping the loops

Question 20

What are the advantages of sinker loop fabrics?

Answer 20

• normally loops are fairly short and inter yarn friction hold the pile to the base meaning they do not need back-coating to be secured.
• have good drape, and are extensible so good for clothing
• air easily trapped in the pile, making them warmer

Question 21

How are knitted / raised floats produced?

Answer 21

-knitted using tuck stitches and missed stitches, creating floats on the reverse of fabric.

Question 22

What is ‘loop back fabric’?

Answer 22

When floats are produced across 3 or 4 needles at every second course, the reverse will be covered in loops, creating loop-back fabric.

Question 23

What does raising do to loop back fabrics?

Answer 23

Makes the fabric into fleece or ‘brushed back fabric’

Question 24

What are loop back fabrics used for after raising?

Answer 24

To produce sweatshirts, joggers, as they are warmer and thicker than plain knits
