4 point system inspection (Four point inspection fabric)

Inspection Procedure:4 point system
· Determine the amount to inspect 10%).
· Select the rolls to inspect.
· Put the rolls on the inspection machine or other viewing device.
· Cut off a 6 inch piece across the width off the end of the roll. Mark the right and left side of the strip. Stop the inspection process every 50 yards and use the strip to check for any shading problems. Also make sure to check the end of the role.
· Inspect for visual defects with the light on at a speed slow enough to find the defects. (The fabric must be checked at a slow rate in order to effectively find flaws). Sometimes you may have to turn the light off to see how a flaw will affect the appearance of a garment.
· Check that the roll contains the correct yardage as stated by the piece goods source.
· Check for skewed, biased, and bowed fabric.
· Mark any defects to the side with colored tape so that they can be easily found and noted.
· Record any defects.

3 inches or less: 1 Point
Over 3 inches, but less than 6: 2 Points
Over 6 inches, but less than 9: 3 Points

The length of the defect is used to determine the penalty point. Only major defects are considered. No penalty points are assigned to minor defects. (A major defect is any defect that would cause a final garment to be considered a second.)
Major Defects:
· Major woven fabric defects include but are not limited to slubs, holes, missing yarns, yarn variation, end out, soiled yarns, and wrong yarn.
· Major dye or printing defects are out of register, dye spots, machine stop, color out, color smear, or shading.
Acceptance Criteria and Calculation:

· # of Points per 100 yds = # of penalty points x 100 Yds inspected

Fabric Quality Inspection:
The quality of a final garment depends on the quality of a fabric when it is received as a roll. Even the most outstanding manufacturing methods cannot compensate for defective materials. Normally, we inspect 10% of the rolls we receive and evaluate them based on a four-point system. This way, we can avoid fabric related quality problems before it is put into production
Four- Point System:
Amount to select: Inspect at least 10% of the total rolls of the shipment.
Selection of rolls: Select at least one roll of each color. If more than one role must be selected, then choose the additional roles in proportion to the total number of roles per color received.

Innovation cotton textile

Innovation cotton textile
Cotton is used to make a number of textile products. These include terrycloth for highly absorbent bath towels and robes; denim for blue jeans; chambray, popularly used in the manufacture of blue work shirts (from which we get the term "blue-collar"); and corduroy, seersucker, and cotton twill. Socks, underwear, and most T-shirts are made from cotton. Bed sheets often are made from cotton. Cotton also is used to make yarn used in crochet and knitting. Fabric also can be made from recycled or recovered cotton that otherwise would be thrown away during the spinning, weaving, or cutting process. While many fabrics are made completely of cotton, some materials blend cotton with other fibers, including rayon and synthetic fibers such as polyester. It can either be used in knitted or woven fabrics, as it can be blended with elastine to make a stretchier thread for knitted fabrics, and apparel such as stretch jeans.
