Testing
All carpet yarns are tested for Dtex, Shrinkage, Crimp , Tensile Strength, Tenacity, Elongation , Spin finish oil and Twist.
Shrinkage test
- Shrink is tested at extrusion and after heat setting
- Heat setting is by superba machines
- After good heat setting yarns are much more uniform and resistant to heat and keep their twist.
Crimp test
-
Crimp of the yarn is effecting its bulkness and directly proportional with its covering power that is joly important for the use in carpet applications.
Strength test
- The warp yarns are under considerable tension so must have good consistent strength
-
The creels are massive so any yarn breakages can cause considerable downtime and is not acceptable.
Spin finish oil test
-
Spin oil is mainly for antistatic effect , dust reductionand easy flow of yarn on creel .
