ESSENTIAL GARMENT CONSTRUCTION

ESSENTIAL GARMENT CONSTRUCTION

is assembled by joining fabrics together with the application of SEAMS & STITCHES.

A seam is a joint of two pieces of fabric in producing a three -dimensional shape of a garment

SEWN GARMENT–

SEAM CONSTRUCTION – Categorised by the British Standards Institution (BS 3870 PART II: 1991, also ISO 4916:1991) The Stitched seams are divided into eight classes:

Class 1 - Plain seam & French seamClass 2 - Welt seam Class 3 - Bound seam Class 4 - Channel seam Class 5 - Ornamental seam Class 6 - Turned hem Class 7 - Edge stitched seam Class 8 - Enclosed seam

SEAMS

SEAMS DESIGNATIONEach stitched seam is designed numerically by five digits:

0.00.00 refers to the CLASS, 1-8;0.00.00 refers to the material

configulation, 01 to 99;0.00.00 refers to needle penetrations,

material configulations, 01-99.

SEAMS

Stitched seams classification are governed by following factors:

BS specification:

1. Components in the seam - Minimum/total components within the seam,

2. Relative position of each component within the seam, and

3. Unlimited and limited width - Width of the component, which ends may either be 'unlimited' or 'limited'.

SEAMS

– Formed by superimposing the edge of one piece of component over the other, these seams are produced with a minimum of two pieces of component. Each component is limited on the same end.

pieces of component, they are produced with minimum of two pieces of component.

One component is limited on one end

– Formed by lapping two

and the other is limited on the other end. The limited edges of these two components are put in opposite directions.

SEAMS

– Constructed by binding the component edge with another narrow component. The seam produced with minimum of two pieces of component.

One component is limited on one end and the other is limited on both ends.

SEAMS

– Two pieces of fabric are laid flat with their edges closing each other without overlapping. Seams are produced with minimum of two pieces of component.

Both components are limited on one end but they are put opposition to each other on the same level.
