Definition
| Excellent sewability, in terms of uniformity of stitches and appearance of seam. Poor abrasion resistance Low strength Low elasticity Does not melt and is resistance to heat from needle Susceptible to breakage during sewing Weakened by many chemicals used in finishing and care Cotton is damaged by dry rot, mold and mildew |
