In order to avoid the quality problems that may
arise due to the improper quality of greige (unprocessed) fabric or yarn, the
following Quality Assurance measures has to be taken.
1)
Physical properties:
- Fiber maturity
- Fiber color
- Yarn CSP
- Tensile / tear strength
- Stains - oil, rust
- Fungus
- Appearance of fabric - weft bowing
- Abrasion marks
- weft missing / warp missing
- Number of cut-ends per squire meter
2) Chemical properties:
- If found low in tensile/tear strength,
fluidity test must be conducted
- Simple indicator tests to ascertain the damage
in cellulose.
- Test for degree of polymerization.
- Analysis pf non-cellulosic residues.
- Tests for sizes
- Tests for fat and wax content
- Purity level of fibers or identification
of contamination in fibers
