Textile Testing
Why testing is necessary in textiles?
The testing of textile products is an expensive business. A laboratory has to be set up and furnished with a range of test equipment. Trained operatives have to be employed whose salaries have to be paid throughout the year, not just when results are required. Moreover all these costs are nonproductive and therefore add to the final cost of the product. Therefore it is important that testing is not undertaken without adding some benefit to the final product. There are a number of points in the production cycle where testing may be carried out to improve the product or to prevent sub-standard merchandise progressing further in the cycle.
Main steps for textile testing:
- Checking raw materials
- Monitoring production
- Assessing the final product
· Investigation of faulty material
· Product development and research
Different properties of fabric testing performed-
(i) Dimensional Characteristics- A) Length, B) Width, C) Thickness
(ii) Threads/Inch – EPI, PPI, CPI, WPI
(iii) Count- Warp & Weft
(iv) Weight- GSM, ounce per square yards
(v) Crimp%,
(vi) Strength
(vii) Abrasion & Pilling
(viii) a) Stiffness b) Drape c) Handle
(ix) Flame Reterdancy
(x) Water repellency
(xi)Crease Resistance & crease recovery
(xii) Shrinkage
(xiii) Air permeability etc and
(xiv) Color fastness of dyed textiles
