Testing of Fibers:
Testing of raw material is very important and in case of spinning raw material could be fibers, so it is necessary to find out the complete parameters of fiber that will help in the process of spinning. The properties of the yarn and fabric are directly influenced by the properties of fiber from which yarn and fabric are made. For testing of fibers, mostly used instruments are USTER HVI and USTER AFIS.
Classification of Fiber Testing:
Identifications of fiber
Grading
Color of fibers
Fiber Length
Fiber strength and elongation
Fiber fineness
Fiber maturity
Trash
Neps
Short fiber index- SFI
Short fiber content- SFC
Immature fiber content
Dust
Testing of Yarns:
Yarn is the principal element of fabric. So, fabric quality directly depends on yarn. Various types of tests are used to identify yarn quality.
Classification of Yarn Testing:
Yarn count or Linear Density
Twist per unit length
Single yearn strength
Lea strength and elongation
Appearance
Evenness and regularity
Hairiness
Fabric Tests:
After the development of the fabric different tests are performed on it to evaluate different parameters. Different strength tests are performed to evaluate the fabric strength.
Classification of Fabric Testing:
Strength and elongation
Length
Width
Thickness
Weight
Number of warp yarn per unit length (EPI)
Number of weft yarn per unit length (PPI)
The count of yarn
Design and construction of cloth
Yarn permeability
Crimp %
Shrinkage test
Stiffness
Drape
Crease resistance and recovery
Abrasion
Thermal properties
Pilling test
Water absorbance and resistance
Colorfastness
