IntroductionFabrics during use are subjected to light, washing, ironing, perspiration, friction, and chemical exposure. some printed and dyed textiles are also subjected to special finishing processes, such as resin finishing, flame retardant finishing, sand washing, brushing, etc., which requires printed and dyed textiles to maintain a certain degree of relative fastness to the color and luster.Color fastness refers to a product's resistance to washing, friction, and other environmental factors.Color fastness is good and poor, Substandard color fastness may pose health risks as, poor color fastness of the product in the wearing process, encounter rain, sweat will cause the pigment on the fabric to fall off and discoloration, the dye molecules and heavy metal ions, etc. may be absorbed by the human body through the skin and endanger the health of the human skin, on the other hand, it will also affect the wearer's other garments to be stained with colors, or with other clothing when washing dirty other Clothing. Because of the great difference in the conditions and requirements of the fabrics during processing and use, the following color fastness tests are available. Color Fastness to Rubbing  Color fastness to rubbing refers to the degree to which the color of a printed fabric remains firm under rubbing. The color fastness of colored materials to rubbing depends on two main factors.Crockmeter to determine the colour fastness of textiles to dry or wet rubbing. A pinned acrylic sample holder ensures rapid sample mounting and repeatability of results.                                  Perspiration  Color fastness to perspiration measures the ability of a printed textile to resist perspiration. Researchers use it primarily to test colored summer garments that come into regular contact with human skin.The specimen is sewn together with a standard appliqué fabric, treated in a sweat solution, clamped to a color fastness to perspiration tester, placed in an oven at a constant temperature, then dried, and rated with a grey card to obtain the test results. Different test methods have different ratios of perspiration solution, different specimen sizes, different test temperatures and times.Perspiration Testerapply for testing perspiration resistance color fastness of all kinds of textile materials & dyeing, colorful textile and test for their perspiration resistance, waterproof, seawater resistance, saliva resistance, chlorine bleach resistance, etamsylate resistance and other performance.                                  Color Fastness to Washing Test Color Fastness to Washing Measures the ability of textiles to resist fading when washed. It tests printed and dyed fabrics. It is a key quality measure for most of these textiles.Washing Color Fastness Testerapply to test dyeing textile color fastness changing degree after washing, it not only do washing color fastness and also dry washing color fastness test.                                   Color Fastness to Light  Color fastness to light is the ability of a textile to resist fading when exposed to daylight or artificial light sources.1.  Colorfastness to Ozone GT-D01B It is intended for assessing the Ozone resistance of color of textiles of all kinds and in all forms when exposed to atmosphere with certain temperature and humidity.2. Suntest & Xenon Arc TesterThe Suntest & Xenon Arc Testers is a powerful Xenon Instrument for conducting accelerated tests of light fastness and photo stability tests.                                   Color Fastness to Sublimation  This is the degree of heat sublimation dyed fabrics experience in storage.This Scorch & Sublimation Tester GT-D03 apply to textile assist color change or transfer capacity under heating condition, simulate textile being ironing and under high temperature & humidity dyeing color fastness to sublimation degree in daily life.                                  Color fastness characterizes a textile's ability to maintain its original hue despite environmental stresses. Users can carry out color fastness tests according to their needs.

Bursting strength is a key mechanical property characterizing the ability of a material to resist rupture when subjected to concentrated loads in the vertical direction. It is primarily measured using ball-type bursting strength testers or hydraulic/pneumatic testing equipment, and includes parameters such as bursting strength value, elongation and rupture pattern. In the textile industry, this index is widely used to assess the durability of knitted, non-woven and coated fabrics, such as sleeve seam integrity in sweaters and toe durability in hosiery and other practical application scenarios for quality control.Bursting Strength Test Principle and MethodBursting strength is measured by applying a concentrated load perpendicular to the surface of a specimen by means of a steel ball or a fluid medium, and recording the maximum force at the moment of rupture and the associated deformation parameters. The main methods include: Ball Burst Strength Method: A steel ball with a diameter of 20-38mm is used to press the specimen at a constant rate, which is suitable for flexible materials such as textiles and polymer films.Hydraulic Bursting Method: Hydraulically push the rubber diaphragm to make the specimen bi-directional expansion, mostly used for thick industrial fabric testing.Pneumatic Bursting Method: compressed air is used to generate a uniform pressure field, especially suitable for assessing the performance of breathable materials.Factors affecting the Fabric Bursting StrengthRaw materials: Different raw materials have different fibre strengths and toughnesses, resulting in large differences in fabric breaking strength. For example, among chemical fibres, nylon has the highest breaking strength, followed by polyester; among natural fibres, hemp has the highest strength, followed by cotton.Yarn properties: The yarn count, diameter, and filament vs. staple fiber composition significantly affect fabric bursting strength.Fabric organisation: The organisation of a fabric has a significant effect on its breaking strength. Tighter organisations have a higher breaking strength, while looser organisations are more prone to breakage.Yarn arrangement: The way the yarns are arranged in the fabric affects the breaking strength. A more uniform yarn arrangement helps to increase the breaking strength of the fabric.Sample Preparation and Testing Conditions: The size and shape of the sample, the method of preparation, and the ambient temperature and humidity during the test will all affect the results.Equipments for Fabric Bursting Strength1.
