Seam | Properties of seam | Appearance | Performance

Properties of seam: Properties of seam are assessed on the following aspects-

Appearance: After sewing, the sewn area is observed for any defects, if present which affects outlook. Normally it is expected that there will be no defective view of stitches, seam pucker, or unsightly view.

Performance: Performance of a seam is assessed according to following criteria-

1. Seam Strength: Strength of a seam should be equal to or slightly less than the fabric strength.
2. Seam elasticity: Elasticity property of a seam should be equal to or greater than the fabric elasticity.
3. Durability: Durability of a seam equal to or greater than the durability of the fabric. Especially during wear and washing, the seam should not fail or damage due to frictional forces and tension.
4. Security: During normal use of apparels, the seam should not fail due to simple reason. Confidence of normal stability of seam is the security of the seam. If the seam fails due to normal reason the situation might be undue.
