This document describes different types of knit fabrics including single jersey, rib, and double jersey. Single jersey has different appearances on each side with curling edges, poor dimensional stability, and light density. Rib fabric has the same appearance on both sides with no curling, good stability, and heavier density. Double jersey also has the same appearance on both sides, no curling, good stability, and the heaviest density.

Type of Knit Fabric
• Basic Types
– Single Jersey
– Double Jersey/Interlock
– Rib Gating
• Fancy Types
– Locust
– Pique
– Tarry
– Waffle
– Fleece
– Etc.

3. Single Jersey
• It’s a single bedded structure can be produce
both in circular bed & Flatbed Knitting M/c

4. 10/9/2018 4
Single Jersey
Identification
• Both side is not same.
• Curling produce for yarn tension/torque
• Lengthwise Direction T/F to T/B
• Widthwise Direction T/B to T/F
• To reduce edge curling-
– For Heavy knitting
• After knitting before linking use steam pressing at the edge.
– For light knit
• After knitting before sewing use Iron at the edge.
• Use Folder on Machine
• Use Sauntering After cut Tubular Fabric

Single Jersey
Identification
• Dimensional stability of single jersey
is poor.
To increase dimensional stability:
• Increase Loop density
• Apply resin finish
• We can unravel the yarn from the
both end.
3. Dimensional Stability:
4. Unraveled:

Single Jersey
Identification
• Good elasticity in width wise direction.
• Laddering can be repaired in flat bed
knitting but not in circular knitting.
– Cause of laddering:
• Needle Head Broken
• Poor Quality materials
• Lose tension
• The density of single jersey is light.
5. Elasticity:
6. Laddering:
7. Density:

7. 10/9/2018 7
Single Jersey
Identification
• All basic sweaters, cardigans,
pullovers for heavy knit.
• Basic T-shirt, polo shirt for light
knit.8. End uses:

8. Rib Knitted Structure
• The word ‘rib’ derives from animal ribs. In this structure
needles head are no t facing directly each other. Rib fabrics
are composed of loops formed in opposite direction. Various
types rib construction are there but common structure are
1×1 & 2×2 and above 2×2 construction like 3×3, 4×4, 5×5 are
Fancy rib but 6×6 rib has special name like Derby rib.

9. 10/9/2018 9
Rib Knitted
Structure
• Both sides should be same in appearance
but semi circle loops observe in between ‘V’
shape loops
• This fabric does not curl at the edges. It is a
balance fabric because of having Wales in both
directions. The reason is both T/F and T/B bed
are active, so tension is uniform on both sides.

2. Edge Curling:

10. 10/9/2018 10
Rib Knitted
Structure
• Dimensional stability is good
• We can unravel the yarn the end
section only (because it forms from
double bed).

4. Unraveled:

11. 10/9/2018 11
Rib Knitted
Structure
• Elasticity can be observed well in widthwise
direction.
• Laddering can be repaired in flat bed
knitting but not in circular knitting
• Density is heavier than single jersey because
loops catch at both sides.
5. Elasticity:
6. Laddering:
7. Density:

12. 10/9/2018 12
Rib Knitted
Structure
– Bottoms, collar, cuff, hem and for
also for full dress.
– Especially lightweight for
undergarments because elasticity
is good.8. End uses:

13. Double Jersey
• If the plain stitches are one behind the other the fabric/
structure is known double jersey. Can be Produce both in
circular & Flat bed Knitting Machine. It is very Tight Knitted
Fabric.

14. 10/9/2018 14
Double Jersey
• Both sides are same in appearance. Both
technical front and technical back has V
shape stitch/ jersey stitch.
• This fabric also does not curl at the edges.
Reason is that it is more balanced fabric because
all needles are active on both sides (T/F and T/B
bed). So tension is uniform on both sides.

2. Edge Curling:

15. 10/9/2018 15
Double Jersey
• Dimensional stability is good
• We can unravel the yarn the end
section only (because it forms from
double bed).
3. Dimensional Stability:
4. Unraveled:

16. 10/9/2018 16
Double Jersey
• Comparison to other knit fabric; (especially
rib) elasticity is poor.
• Laddering can not be repaired in both flat
bed knitting and circular knitting. Because
both side needles are active at opposite
direction.
• In comparison to other knit fabric; density is
heavier.
5. Elasticity:
6. Laddering:
7. Density:

17. 10/9/2018 17
Double Jersey
• Normally for heavy knitwear Vast
because it is fitted.
• Light knitted is preferred for
sportswear (sports T-shirt) because
it absorbs sweat well and
dimensional stability is good.
• For ladies skirt And also for tube
fabric to make pocket
