Sewing-1



Sewing

1. Seam: A seam is the application of a series of stitches or stitch types to one or several thicknesses of material.

Stitching is applied to situations where there is only one piece of fabric, such as when fabric edges are neated or hems created, and where decorative sewing is involved.

Objective of Sewing: Are the construction of seams whcih combine the required standards of appearance and performance with in appropriate level of economy in application.

Good Apppearance of Seams: It means smooth fabric joins with no missed or uneven stitches and no damage to the material being sewn.

Performance of Seams: It means the achievement of strength, elasticity, durability, security and comfort, and the maintenance of any specialised fabric properties such as waterproofing or flameproofing.

1. Seams must be strong as the fabric, in directions both parallel to and at right angles to the seam.

2. Seams must be durable to the kind of abrasion experienced in washing and wearing as well as secure against fraying apart or the unravelling of the stitches.

3. A seam in a close fitting garment must not present an uncomfortable ridge or roughness to the skin.

4. It must not damage the fabric along the stitch line.


Factors to be considered while sewing

1. Seam Type: Particular configuration of seams in fabrics.

2. Stitch Type: Particular configuration of threads of in the fabric.

3. The Sewing machine feeding mechanism- It moves the fabric past the needle and enables a succession of stitches to be formed.

4. The needle which inserts the thread into the fabric.

5. The thread which forms the stitch which either holds the fabric together, neatens it or decorates it.
