If nosotros define the steps of cloth from nascency till halt travel (life cycle) so it volition travel similar following:
- Design idea : Conceptual development
- Development: Development of conceptual idea inwards reality equally samples.
- Lab dip approving : First approving for the mass production

- End use: Final retailing of clothe
INSPECTION PROCEDURE:
There are many systems for the character audit of cloth / slice goods.
Most familiar arrangement is 10 indicate system, Dallas arrangement in addition to four indicate system.
1. 10 indicate system: Method of indicate calculation
In this arrangement points should non travel on the total yardage of cloth roll.
Suppose penalization indicate of a ringlet is 50 in addition to total yardage is 50 than it is ok in addition to volition travel considered equally foremost quality. If, penalization points exceeds than the total yardage such equally 50 penalization points out of 50 meter ringlet than it should travel considered equally 2nd quality.
2. Dallas System: This arrangement was introduced yesteryear “Dallas clothe manufacturing association” in addition to it was alone for knits manufacturing manufacture thence it is non the consummate arrangement which could travel followed.
3. Four indicate system: This is the most familiar in addition to widely accepted system. At to the lowest degree 10% peace goods (Fabric) should travel inspected nether this system. Selection of rolls should travel of each color in addition to randomly selected. Following is the method of point’s calculation inwards this system.
The size of defect decides the penalization points. In 1 linear yard the maximum of four points should travel charged.

Normally xl points are acceptable inwards per 100 yards.
Example:
- Suppose 1 consignment has come upwardly of 3000 yards.
- As per dominion 10 % slice goods are inspected.
- Out of 300 yards total penalization points 205 reported.
However 1 may analyze the private ringlet wise rejection.
Example: Inspected 10 rolls. Found 3 rejected.
In this instance 100% inspection would travel required for separation of skillful in addition to bad ringlet of fabric.
It is totally depend on mill management for the inspection % of goods. The primary criteria is ultimate goods should travel defect free.
