Many of our furniture, such as sofas, ottomans, etc., often use fabrics of different materials. So what are the ways to test the quality of fabrics? Here are some methods of cloth detection.
1. Calculation of the score
In principle, after each roll of cloth has been inspected, the scores can be added up. Then, the grade is assessed according to the acceptance level, but since different cloth seals must have different acceptance levels, if the following formula is used to calculate the score of each roll of cloth per 100 square yards, it is only necessary to formulate a score per 100 square yards. According to the specified score under the code, the grades of different cloth seals can be assessed.
(Total score x 36x100)/(The number of inspected yards x the width of the cloth that can be cut) = the score per 100 square yards
2. Types of woven fabrics
a. All man-made fabrics, polyester/nylon/acetate products, shirts, fabrics, rayon fabrics, worsted wool, 20 points/100 square yards, 16 points/100 square yards;
b. Denim canvas Poplin/Oxford striped or gingham cotton shirting spun rayon fabric Wool fabric Striped or checked fabric/Dyed indigo yarn All special fabrics, Jacquard/Dobby corduroy/velvet/stretch coarse Cotton twill/man-made fabric/blend 28 points/100 square yards 20 points/100 square yards;
c. Linen muslin 40 points/100 square yards 32 points/100 square yards;
d. Dupioni silk/light silk 50 points/100 square yards 40 points/100 square yards;
3. Types of knitted fabrics
a. All man-made fabrics, polyester/nylon/acetate products, rayon worsted wool blended silk 20 points/100 square yards 16 points/100 square yards;
b. All professional cloth, indigo yarn velvet dyed from jacquard fabric/Dobi corduroy rayon fabric woolen/spandex 25 points/100 square yards 20 points/100 square yards;
c. Basic knitted fabrics (combed cotton/blended cotton) 30 points/100 square yards and 25 points/100 square yards.
d. Basic knitted fabric (cotton carded by carding machine) 40 points/100 square yards 32 points/100 square yards;
4. Sampling Procedure
The selection of papers to be inspected is entirely random. Textile mills are required to show the inspector a packing slip when at least 80% of the rolls in a batch are packed. The inspector will select the papers to be inspected. Once the inspector has selected rolls to be inspected, no further adjustments may be made to the number of rolls to be inspected or the number of rolls that have been selected for inspection. During an inspection, no yardage of fabric shall be cut from any roll except for recording and color checking. All rolls of cloth that are inspected are graded and the defect score is assessed.
5. Repeated flaws
a. Any recurring and/or recurring defects will constitute repeat defects. Four points must be awarded for each yard of fabric for repeated defects.
b. Regardless of the defect score, and roll with more than ten yards of cloth containing repeat defects shall be deemed unqualified.
6. Full-width defects
a. Rolls containing more than four full-width defects per 100 square yards shall not be rated as first-class.
b. Rolls with more than one major defect per 10 linear yards on average will be classified as unqualified, no matter how many defects are contained within 100 yards.
c. Rolls containing a major defect within the first or last three yards shall be classified as unqualified. Major defects will be considered three or four points.
d. If the cloth has obvious loose or tight threads on one selvage, or ripples, wrinkles, creases, or creases on the main body of the cloth, these conditions cause the cloth to be uneven when the cloth is unfolded in the usual way so that The rolls cannot be graded as first class.
