Step by step of Fabric Inspection

fabric inspection 4-Point Inspection System:

Good quality on the garment so it depends on the quality of the fabric / fabric when received in the form of a roll. Normally, we check 10% of the roll we receive and check it based on the four-point system. In this way we can analyze and inform the fabric status to be followed up immediately before going to the production process

Four-Point System: The number examined is at least 10% of the total rolls received. Roll selection: Choose at least one roll per color. If more than one role must be selected, then choose an additional roll in proportion to the number of roles per color received.

4-Point Inspection System: Four-Point System, a standard established under ASTM D5430 - 07(2011), is a standardized Test Methods for fabric Visually Inspecting and Grading. Four-Point System is widest acceptance in fabric inspection due to its practical, impartial, and worldwide recognized. The four-point system derives its name from the basic grading rule that a maximum of four penalty points can be assessed for any single defect and that no linear meter can be assigned more than four points regardless of the number of defects within that piece.

Defect Classification (4-Point System):

Size Defect Penalty

The length of the defect used to determine the penalty point. Only major defects are considered. There are no penalty points assigned to minor defects. (A major defect is any defect that will cause the final garment to be considered seconds.)

Major Defect: Defect the main woven fabrics including but not limited to slubs, holes, missing threads, yarn variations, finally exits, dirty threads, and wrong threads. Dyeing or defect outgoing print, colored spots, stopping the machine, exit color, smear color, or shadow. Acceptance Criteria and Calculations:

· 40 points per 100 meters is the defect level received

· # Of Points per 100 yds = # of penalty points x 100 yds checked

Inspection Procedure:

Receive approval color and quality swatches
Check lot size, lot number, roll number etc.
Randomly draw 10% of the lot or as per AQL chart.
Delivery of less than 1,000 yds-100% inspection
Delivery of 1,000 yds to 10,000 yds. to inspect at list 1,000 yds.
Delivery of more than 10,000 yds. inspection 10 of the lot.
Check that the roll contains the correct yardage as stated by the source of a piece of goods.
Check for slanted, biased, and bent fabrics.
Mark each defect with colored ribbons so they can be easily found and recorded.
Record any defects

CUTTING PROCESS

QUALITY CONTROL IN CUTTING: Cutting is the process of cutting fabric according to existing marker patterns and the correctness of the markers and QC cutting has been checked.

In brief what is done by the QC cutting section is checking the fabric mat, the fabric does not wave, does not fold, the bottom to top fabric must be the same, and the fabric shrinkage. Then check the results of the piece, the piece must be in accordance with the sample and size tolerance.

Inspection procedure on cutting (QC Cutting):

Check the top sheet of cloth up to the bottom sheet of paper with the position of the marker paper.
Check and match the pattern component with the pattern component found on the marker paper whether the pattern component is complete or not. The QC officer must record all findings on the inspection report sheet.
Check whether or not there are cut errors on each component line.
Check interlining with patterns (if garment components use interlining and embroidery)
Error cutting on the part that should have been re-cut on the spare cloth, recorded and re-cut

More details are as follows

Check the fabric construction, fabric color, fabric design, the inside of the fabric, and the fabric center line. Also checks the fabric quality.
Check the markers, whether the size / size ratio has fulfilled all the ordered sizes
Check the results of spreading / whether the cloth that was stranded was completely flat and not wavy and straight.
Check the cutting method
Inspection of cut results, whether all cut results are really in accordance with the original pattern / pattern provided by the buyer / buyer.
Check the results of the cut, whether the stripe or box of the component pieces is really matching and balancing

TESTING OF RAW MATERIALS (FABRIC)

Fastness and Color Blemishes Tests for Washing

Launder Test Equipment with tubes and steel balls (20 pcs), Neutral PH Soap 0.2% Volume - 100

milliliters, 40 degrees centigrade, 15 x 5 cm test sample, 15 x 5 cm Polyester and Cotton test indicator
