Features of Interlock Knitting ( Machine, Process and Structure)

1. Machine has two beds, machine may be flat or circular but generally circular.

2. There are two subsets of needles in each bed, the subsets re known as short and long needles respectively.

3. Two sets of cam system, i.e. cam path in each bed accommodate short and long needles in the other bed and vice-versa.

4. Short needles in one bed make loops in conjunction with short needles in the other bed. Similarly, long needles in one bed make loops in conjunction with long needles in the other bed.

Interlock fabric structure

5. Separate yarns are to be supplied to the short needles and long needles for loop formation through separate feeders.

6. Short needles and long needles don’t make loop simultaneously but with a time gap.

7. Loops made by one set of needles are locked by the loops made by the other set of needles.

8. Each interlock course is composed of two rib courses.

9. Minimum two yarns are needed to produce a fabric.

10. Fabric has a double face as well as a stable structure.

Interlock Circular Knitting Machine

11. Fabric surface is smooth.

12. Fabric is equally thicker to rib but much more compact.

13. Fabric neither curls nor ladders.

14. Like a rib, an interlock can be made of a different combination of needle gaiting.

15. Interlock fabric made from 2×2 needle gaiting or 2×2 rib is known as eight lock fabric, as there are total eight loops in a unit of interlock loop.

16. Machine is complicated and costly.

17. Fabric are dimensionally stable, heavy and costly.
