Fabric inspection standards
Fabric inspection standards
Fabric model: Fabric
Inspection standards:
1. Fabric density, the warp and latitude lines per square inch are required to be above 165.
2. The fabric thickness is required to be above 0.075MM.
3. The distance between the edge of the fabric and the eye of the needle should not exceed 3CM, and the edges of the fabric should not be tight or compressed.
4. The width of the fabric should be above 153cm, and the effective width after removing the selvedge should not be less than 149CM.
5. The fabric should have a moderate feel and should not be too hard or too soft; there should be no white wrinkles after softening.
6. The slope of the fabric tail shall not exceed 2CM.
7. The surface of the fabric should be clear, the color should be bright and even, and there should be no color cast, oil stains, etc.
8. The fabric must not have more than two draws (no more than 0.2CM) and two holes (no more than 1CM) per 100 meters.
9. The weight of the fabric per meter is 62 grams, and the length of the lining of each roll must be enough yards and meters (errors within 1 meter are acceptable).
10. Put the fabric into the cup, add Weiwei and soak it in warm water at 50 degrees for 15 minutes. If there is color in the water in the cup, it means that the lining has faded; it is considered unqualified.
1. Purpose:
In order to ensure that the fabrics delivered by suppliers meet the company’s quality requirements, this inspection specification has been formulated as a basis for quality inspection of purchased fabrics to ensure quality.
2. Scope:
All kinds of fabrics supplied by our company belong to this category.
3. Responsibilities:
Incoming material quality controllers are responsible for inspecting and testing fabrics in accordance with this standard, making judgments on product quality status, recording quality status, labeling unqualified products, and making recommendations on how to handle unqualified products.
4. Definition:
4.1 Warp defects: defects extending along the warp direction of the fabric.
4.2 Weft defects: defects extending along the weft direction of the fabric.
4.3 Local defects: limited and measurable defects.
4.4 Dispersed defects: Defects that are widely distributed and difficult to measure.
5. Operation standards:
5.1 Carry out incoming material inspection according to the requirements of material purchase order, sample sealing and drawings;
5.2 The specifications of the cloth and the thickness of the coating should be uniform, without delamination, pinholes, or blistering. The weight should be ±2 grams compared with the sealed sample;
5.3 The fabric is well packaged and has no stains or damage;
5.4 There is no yarn drawing, yarn throwing, or yarn breakage. The fabric meets the sample sealing requirements, the lines and patterns are clear, and there is no fading after dry and wet friction;
5.5 The tensile strength meets the impact test requirements (150 pounds weight, 6 inches height, 25 impacts) without breaking, and the longitude and latitude lines meet the sample sealing requirements;
5.6 Cloth inspection machine inspection allows 1 drawn yarn per square meter and 3 pinholes with a diameter less than 0.5mm. Short codes are marked and deducted.
5.7 Randomly select Oxford cloth/PE cloth/strap products and cut them to a length of 12.75 inches and a width of 3.25 inches for ultraviolet color fastness testing. After 40 hours of testing, the sample is considered to be qualified when compared with the comparison plate and is rated ≧4.
5.8 Classification of shortcomings
Major Disadvantages Minor Disadvantages
The size, specifications, and surface quality do not meet the order requirements; the fabric is stained, damaged, drawn, thrown, broken, color difference, unclear lines, wrinkled, and the impact strength does not meet the requirements; the coating thickness is uneven, delamination, and blistering , weight does not match, fading. The PVC coating does not fall off when rubbed, and the color fastness is unqualified. There are light and heavy stains in some parts, but there are no abnormalities after treatment. The color has changed slightly, and the comparison with the sealed sample is not obvious. There is 1mm2 of unpainted part of the coating
5.9 Processing method:
The inspected fabrics with defect levels within the standard will be judged as qualified batches, and those that exceed the standards will be judged as unqualified batches. Unqualified fabrics will be implemented according to the “Unqualified Control Procedure”.
6. Reference documents or standards:
6.1 Quote GB/T2828.1-2012
6.2 Auxiliary fabrics with minor defects can be deemed qualified, but the right to trace them is retained. At the same time, improvement suggestions will be provided to the supplier, and follow-up inspections will be conducted during production and use. If any abnormalities are found, they will be stopped from use immediately and will be returned or exchanged.

8.1 The “Incoming Material Quality Abnormality Form” has a shelf life of 2 years
8.2 The retention period of “Incoming Material Inspection Record Form” is 2 years RlPjMA
