different types of seam
Different types of seam
01) Super imposed seam:
The seam of class-1 is called superimposed seam. This is the most common & mostly used seam for joining fabrics. In this seam, two plies of fabric are placed on one another perfectly & then the fabrics are sewn. The sewn edges of the fabrics remain in the same side.

In side seams of shirts, trouser, children wear etc. Piped & French seam are used for decorative purposes.

02) Class-2- Lapped seam:
The seam of class-2 is called lapped seam. At least two plies of fabric is required to produce this type of seam. The two Sewn edges remain in two opposite sides of the sewing line/seam line.

This class of seam is not mostly used for sewing garments. This seam is used in sewing jeans pants, lunges etc.

03) Class-3- Bound seam: The seam of class-3 is called bound seam. For producing bound seam at least two plies of fabric are required. The edge of One ply of fabric is bounded by the other. Folder is used in sewing machine for producing bound seam.


Used in sewing men’s underwear, Guernsey, pants, sleeping suits etc.

04) Class-4- Flat seam:
The seam of class -4 is called flat seam where zigzag stitches are used by 2-needle sewing machine. In this seam two plies of fabric are placed side by side & then they are sewn together by zigzag stitching.

This seam is widely used in under garments & in knitted items.

05) Class-5-Decorative Seam:
The seam of class-5 is called decorative seam. This seam is used in order to decorative purpose. The fabric which we used that would be folded in several times and then according to the under side of the folded part of the fabric stitch can be produced.

Cartains,Table clotchs,Furniture wears,Decorative ladies wears et

06) Class-6-Edge Neatening:
The seam of class-6- is called edge neatening which is used to holds the edge of the fabric such that the yarns of the fabric can not open easily.All the over Lock stitch is edge neatening class seam.

To protect the fabric edge such that the warp yarn of the fabric can not easily open.

This experiment is very helpful to us. By this experiment we can learn about various types of seams. This experiment will be helpful for our future practical life. So we should be done this experiment very carefully & sincerely.
