3 - Any type of Fabric gray,bleached,dyed,woven,knitted or on any machines needs testting for fabric strength width wise and length wise,shrinking percentage in gray and finished stage,trash content in gray stage,color fastness to washing,rubbibg test,cloth construction or fabrics number of threads per sq inch.selvedge parameters and fastness to light.
4 - All yarns used in Industry of all type of fabrics also need all tests mentioned above.
