Colour Fastness of Textiles | Color Fastness To Washing Colour Fastness The resistance of colour of textiles to fade or bleed against different agencies such as light, wash,water, perspiration, rubbing, acid, alkali,hot pressing, bleaching etc. is called colour fastness. Colour fastness is a term used in the dyeing of textile materials, meaning resistance of the material’s colour to fading or running. The term […]
Identification of Textile Fibre A: Burning Test :- Textile fibres can be identified by observing the burning phase of these fibres in flame . All natural and regenerated fibres are burnt to ash and special smell is observed for each fibre. Synthetic fibres on burning contract and form beads. All cellulosic fibres such as jute, […]
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 […]
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 […]
Martindale Pilling And Abrasion 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 […]
Fabric Thread Density Testing For Woven Fabric: Picks per inch : The number of weft thread per inch is called picks per inch. Ends per inch : The number of warp thread per inch is called ends per inch. For Knitted Fabric: Courses per cm : Course is a row of loops across the […]
Fabric Tensile Strength Test Methods Tensile Strength Testing: This is referred to as a strength test where the load is applied along the direction of the test sample. Tensile strength test of fabric is divided into two groups- Strip test Grab test. Strip Strength Test: Five fabric samples are extended in a direction parallel to […]
Air Permeability Test by Shirley Air Permeability Apparatus Air permeability: The air permeability of a fabric is the volume of air measured in cubic centimeters passed per second through 1 cm2 of the fabric at a pressure of 1 cm of water. Air resistance: The air resistance of a fabric is the time […]
