Abrasion and Abrasion Resistance Test Abrasion: Abrasion is one aspect of wear and is the rubbing away of the component fibers and yarns of the fabric. Abrasion may be classified as follows- Plane or flat abrasion-A flat area of material is abraded. Edge abrasion-This kind of abrasion occurs at collars and folds. Flex abrasion-In this […]
Different Types of Sewing Thread Sewing thread According to the definition given by ASTM, sewing thread is a flexible, small diameter yarn or strand usually treated with a surface coating, lubricant or both, intended to be used to stitch one or more pieces of material or an object to a material. It may […]
Air Jet Spinning Air Jet Spun Yarn 1 . The air-jet spun yarn is fascinated yarn consisting of a core of parallel fibers held together by wrapper fibers. 2 . The structure of air-jet spun yarn is essentially that of comparatively straight central core of fibers held together by taut surface fibers wound onto the […]
Spin Finishes , Sizes and Grease Spin finish: A spin finish is a preparation applied by the manufacturer of MMF to staple fibers . It is used in the form of a water- based emulsion and contains anti-static agents, emulsifiers and lubricants. Size: Sizes are applied by the spinner of MMF to filament yarns […]
Flammablity Test Flammability It is the ability to burn or ignite any substance by means of fire or any kind of combustion. Various test procedures exist to determine the flammability. In domestic sphere many serious and tragic accidents are the results of clothing catching fire.Flameproof fabrics are absolutely necessary for protective clothing in many industrial processes […]
Fabric Width and Thickness Test Textile Testing : Main steps for textile testing : Checking raw materials Monitoring production Assessing the final product Investigation of faulty material Product development and research Different fabric tests : Dimensional Characteristics – A) Length, B) Width, C) Thickness Threads/Inch – EPI, PPI, CPI, WPI Count- Warp & Weft […]
Crease Resistance and Recovery Test Crease: This is a fabric defect evidenced by a break line or mark or fold in a fabric generally caused by a sharp fold. Crease appears when the fabric is distorted in such a manner that part of it is stretched beyond its elastic recovery. During creasing the upper […]
