Sewing is an operation in the Garment Industry.

Sewing Operation

Sewing is the primary step in creating garment Industry or similar products. Sewing is the process of joining different components of garment industry using the help of needles and thread. Without thread and needle we could also create clothes using different methods of joining such as welding, adhesives, etc. In general, there are two components that are involved in sewing that is. that is. sewing stitches as well as seams. Sewing is the most significant among the various methods of garment Industry joining. The principal reason for sewing is to make seams.

The process of joining “sewing” is characterized in terms of the details regarding the sewing thread, the fabric, as well as the structure of the link (thread/laying of fabric). Sewing is a method of joining by the linking that connects one or more stitching threads with the fabric. The way, location and the number of interlacing or linking points in the fabric define the joint that is created.

Sewing is the art of securing or attaching objects by stitching them with thread and needle. The term is used to describe the procedure employed in factories to produce various kinds of clothing as well as other items made by gluing diverse components over the sequence of a planned process. Sewing is the process of connecting parts and assembling them together to form a garment Industry. The fundamental sewing rules are:

• Stitches,
• Seams,
• A technique of sewing.

Seam:

A seam is a line that occurs when two fabrics are stitched together in a garment Industry, or other items. A seam is simply the stitching line. Seams are stitched to lines of seams. This is defined as the amount from the seam’s line to the edge of the cut. The typical seam allowance will be (1.5 centimeters) broad.

Property of seam

• Strength of the seam
• Elasticity
• Durability
• Security
• Comfort
• Special properties:
• Waterproof
• Fire proof

Types of seams:

There are eight kinds of seams. They include:

• Class-1: Superimposed seam
• Class 2 Lapped seam
• Class-3 Bound seam
• Class 4 Flat seam
• Class-5: The decorative seam
• Class-6: Edge neatening
• Class-7
• Class-8

Stitch:

Loops or loops made of several threads, when is bound to one another, or by interlacing and interloping or by combining the threads when sewing fabric, each of these units is known as a stitch.

Stitch types:

There are 70 kinds of threads. However, between 18 and 20 types of stitch can be utilized in the textile industry.

All stitches are part of six classes:

• Stitch class 100
• Stitch class 200
• Stitch class 300
• Stitch class 400
• Stitch class 500
• Stitch class 600

Formulae for Thread Consumption to various types of stitches:

1. Stitch Type 101 (Single chain stitch with thread)

C = ( 3N + 2T ) + S

2. Stitch Type-301 (Single thread lock stitch)

C = ( 2N + 2T ) + S

3. Stitch Type-401 (Single needle chain stitch)

C = (4N + 2T) * S

4. Stitch Type 504 (Three threads across edge stitch)

C = ( 3N + 4W + 4T ) + S

Here,

C= Thread Consumption

N = Length of Stitch

T = Thickness

S is Stitch Per inch (SPI)
