Material Quality Manual

This manual is provided to understand Fabric inspection process and requirements to deliver the highest possible quality as well as report all test results as per your Customer requirements.

Although this manual describes general quality requirements it is also expected manufacturers to develop a positive culture of quality.

This culture must begin with management commitment to prevention-based and continuous improvement- based quality systems including:

 Allocating appropriate resources to ensure quality systems are effective

 Encouraging active participation of all workers in improvement efforts

 Ensuring that processes are stable, capable, and centred through the application

    of statistical data analysis techniques

 Documenting systems, processes, procedures, etc. as necessary to maintain effective operations

Greige Fabric Quality Requirements

 

  This is a guideline to the factory for evaluating, grading and      separating the outgoing quality of fabric to be used for your Clients.

  This is important for the fabric manufacturers to note on what are the expectations of your customers about fabric quality.

  This process also assists factories in detecting defects and preventing substandard fabric.

  We have described widely recognized inspection procedure as a training framework for inspectors.

  Our ultimate goal is to promote communication and align procedures between the factory and the customer to resolve quality problems.

Inspection Requirements

Area

The inspection area should be:

 Open, clean and dry

 Dust Free

 Well lit

 All the inspection machines should be visible to Manager

 Free enough to move incoming trolleys

 

Equipment

 

Inspection Machine: 

 

 The inspection machine should be equipped with a variable speed drive, a Electronic Length Counter & a mechanical counter meter, and an undercarriage light to see through the construction and an overhead light to inspect the face of the fabric.

 Every machine should be attached with Weighing Scale and need to check actual GSM Vs Allowed GSM

 Inspection Speed: The frame should be capable of running up to 27 meters per minute) and should have both forward and reverse controls.

 Viewing Distance: The inspection should be performed from an observation distance of 2 to 4 feet (60 to 120 centimeters) so as to get full vision of the fabric width.

 Lighting: Overhead Customer required lighting is recommended for the inspection.

 The surface illumination level should be a minimum of 1075 lux (100 foot candles).

Calibration and Maintenance

 Inspection frame should be included in your periodic maintenance plan.

 All components of equipment which can output a quantifiably value needs to be calibrated annually e.g. Speed drive/ Counter/ Weight

 

Tools

 Measuring Tape

 Pick Glass

 Scissors

 Defect Stickers / Tags

 Selvedge Defect Flags

 Inspection Report Forms

 

Approved Item Swatch

 Every Inspector is required to use the QC approved Fabric swatch in Inspection stage as a quality reference sample for hand-feel/ Color and aesthetics verifications in bulk production.

 This approved item swatch must be properly stored for use in quality comparison.

 Keep a clean sample folder with appropriate information such as Customer name, item number, color name, date approved, Approved test report, Production SPEC, and any other relevant information.

Color Evaluation 

 

 Color Standard: Check the head-middle-end sample in the light box against the lab-dip under primary & secondary light source. This process should be done once for each color inspected.

 

 Shading within the roll: Check for shading at the beginning, in the middle and at the end of each roll inspected, using the head-middle-end sample for comparison.

 Side to center

 Side to side

 End to end

 

Color Continuity Card: Check for color consistency between the dye-lots. Cut a small sample (about 2 x 2 inches or 5 x 5 centimeters) from the left side, the center and the right side of the head-middle-end sample of each inspected dye-lot and attach to the color continuity card. Ensure that cards are labeled. Check the samples against approved lab-dip. Note any significant variation of shade from roll to roll.

FIDAS SOP5

Inspection Procedure / Execution

 

It is compulsory vendor to inspect 100% of all outgoing shipments, identify, label and records defects and ship only first quality materials.

 The Inspection team should be familiar with all inspection procedures and standards to ensure that your internal inspection is capable of at least meeting or better exceeding customer  expectations.

 

Color and Aesthetics

 

 Cut a head-middle-end sample across the width of the fabric, preferably about 2 Meters inside of each dye-lot.

 This sample will be used for color and aesthetic verification to ensure lot to lot, head to end fabric consistency.

 

Aesthetics Evaluation

 

 Inspect overall hand-feel and appearance against customer approved item swatch in development stage for cleanliness, texture, recovery, drape, resilience, wrinkling, etc.

 If the aesthetics does not match the sample, Inspector need send that much of fabric for reprocessing and re-inspection

 It is inspection Manager’s responsibility to obtain the swatch from QC to ensure that the reference sample. This sample will be used by the Inspector for, hand-feel and aesthetics verification..

 The reference Sample size is 12 x 12 inches (30 x 30 centimeters) cut out from the approved batch.

 This reference sample must be properly stored for use in quality comparison. Keep a clean sample folder with appropriate information such as Customer name, item number, color name/code, date, batch number, and any other relevant information.

 

Visual Inspection

 

 Once the color and aesthetics have been checked and approved, begin the visual inspection for defects.

 Defects which are not desirable and are clearly detectable on the inspection frame will be assigned points as shown in the Four Point Table.

 The Four Point system will be applied to all fabrics, i.e. woven, circular knit and warp knit.

 Always inspect the side which will be used as the face in the finished garment. Mount the roll on the inspection frame with the face side up.

 

Fabric Width

 

 Measure the fabric width at the beginning, in the middle, and at the end of every roll.

 If a variation in fabric width is found, call Inspection manager to determine if the fabric is usable and if a replacement is necessary.

 At this point, the inspector should also check the condition of the selvedges. The selvedges should as per customer requirement, lay flat, be free of tension, and should not have a tendency to curl.

 

Roll Length

 

Measure and record the length of each roll inspected. Ensure the roll length is based on your customer specifications. If no specifications available, calculate GSM and roll weight should not exceed 75Kgs

 

Inspection for Defects

 

 It is the responsibility to train and/or conduct internal certification for the inspectors according to international quality requirements.

 The responsibility lies with the inspectors to  inspect each material type based on Four Point System before shipped.

 Four Point System

 

A widely recognized inspection method frequently used in the textile industry.

 

It is a technique issued by the American Society for Testing & Materials with reference to the designation ASTM D5 430-93

 

Start the Inspection Machine and inspect for defects. Run the frame at 8-15 minute.

 

If a defect is observed:

 Faults are classified and scored with penalty points of 1, 2, 3 and 4, according to their size and significance.

 Each defect should be counted as a separate defect even if the nature is the same and then based on the points allocated to each defect, total points should be calculated.

 

 Four Point Table

 

Vertical Defects(along the length)Length Points Horizontal Defects(along the width)Width Points
DEFECT SIZE POINTS DEFECT SIZE POINTS
0.1 to 3.0 in (0.1 to8.0 cm) 1 0.1 to 3.0 in (0.1 to8.0 cm) 1
3.1 to 6.0 in (8.1 to15.0 cm) 2 3.1 to 6.0 in (8.1 to15.0 cm) 2
6.1 to 9.0 in (15.1 to 23.0 cm) 3 6.1 to 9.0 in (15.1 to 23.0 cm) 3
9.1 to 36.0 in (23.1 to 92.0 cm) 4 9.1 to full width (above 23.1 cm) 4
 
Note: 
A maximum of 4 points may be assigned to any one linear yard), regardless of thenumber or size of the individual defects.
For a continuous lengthwise running defect, 4 points and 1 defect will be assignedto each linear yard where the defect exceeds 9 inches (23 centimeters).
Example: Short End/ barre effect on the full roll in 100linear yards: 400 points should beassigned with 100 defects
Mark the defect at the selvedge and/or at the defect.
Record the defect and the assigned points on the inspection worksheet.
4 Point System

Inspection Results

 

Complete the worksheet and calculate the total points of each inspected roll and the total of the inspected linear yards/meters. With this information use the appropriate formula below to calculate the Average Points

 

Defect Points Per 100 linear yards or linear meters or Square Yards/Meters

 

Points/100 Linear yd2 = Total Points of inspected roll x 36 X 100

Total Inspected Yards x Fabric Width in inches

 

Points per 100 Square Yards = Total Points for the roll x 3600

Inspected Yards x Cuttable Fabric Width (inch)

 

Points per 100 Square Meters = Total Points for the roll x 100,000

Inspected Meters x Cuttable Fabric Width (MM)

 

For Shipment

  Total Shipment Points per 100 Sq. Yards = Total Average Points per Linear Yard x 3600

 Shipment Inspected Yards x Cuttable Fabric Width (inch)

 Total Shipment Points per 100 Sq. Meters = Total Average Points per Linear Meter x 10,000

 Shipment Inspected Meters x Cuttable Fabric Width (MM)

 

Evaluation Guideline

Factory will evaluate a vendor’s quality performance based on the point count system,

using the following guideline:

 

  Accept / Reject Procedure

Fabric Manufacturer should not ship any roll or shipment with defect points exceed the evaluation guidelines specifically mentioned by the customer.

Sometimes Inspection Manager might communicate with Customer prior to the shipment if the average points of any roll shows a higher number than allowed.

 

 Reporting

 The inspection is intended to determine the shipment quality and to capture information for quality performance evaluation of fabric manufactured.

 One inspection report should be completed for each Item / color inspected and send a copy of the Inspection Report to customer prior to or with shipment.

 Inspection Report information containing inspection date / shipped date / season year / buy month / garment factory / order number / item number / batch number / dye lot number / color code and color name / inspection points / inspection results / yardages / weight / width … etc. should be clearly visible on documentation with English language

 Records should be kept at least 2 years and available to your customer upon request.
