The color fastness to rubbing is the most basic evaluation index for the color fastness of textile products. The main problems of SME products in terms of color fastness to rubbing are: 1. The color fastness to wet rubbing of medium and dark cotton, linen and their blended products is mostly below 2-3, which is lower than the requirements of general standards. 2. The color fastness to dry rubbing of some dark, thin and fuzzing products containing wool is much lower than that of wet rubbing. 3. The color fastness to dry rubbing of some rough or raised fabrics, including paint dyeing and printing products, does not meet the minimum requirements of the standard. 1.1 Color fastness to wet rubbing Direct dyes are used for the dyeing of cellulose fibers, and the color fastness to wet rubbing and the color fastness to washing are not ideal. Causes: The affinity of direct dyes to cellulose is mainly based on dipole attraction and dispersion. The combination of this adsorption is not strong, especially in the wet state, the hydrogen bond may be stronger. Insoluble azo dyes dye cellulose fiber products, and their color fastness to rubbing is not ideal. Causes: Factors Affecting the Color Fastness of Reactive Dyes to Wet Rubbing 1. The structure and characteristics of reactive dyes themselves 2. The properties of cellulose fabrics 3. Pre-treatment effect, cloth surface damage and smooth surface 4. Dyeing process and the effect of soaping after dyeing 5. The effect of fixing treatment after dyeing the fabric 6. The effect of dyeing fabric finishing and the effect of cellulose fiber degradation Fiber fabrics dyed with reactive dyes will cause color transfer in the wet rubbing fastness test. major factor: The water-soluble dye fades the original color and stains the rubbing cloth during rubbing. Part of the dyed fiber breaks when rubbed, forming tiny colored fiber particles, causing staining. The color fastness to wet rubbing of fabrics dyed with reactive dyes is closely related to the depth of dyeing. Among them, the supersaturation of the dye is the most important factor. How to effectively improve the color fastness to wet rubbing of fabrics? Proper pre-treatment of cellulose fiber before dyeing, such as mercerizing, singeing, cellulase finishing, desizing and scouring, bleaching, washing, and drying, can improve the surface finish and hair effect of the fabric, and reduce friction resistance. , Reduce floating color. 1.2 Color fastness to dry rubbing: Some specific fabrics (lightweight fabrics, rough surface or sanded fabrics, raised fabrics) do not meet the standard requirements. Lightweight fabrics fail to meet the requirements for dry friction resistance. Causes: Because the fabric structure is relatively loose, during dry friction, the sample will partly slip with the movement of the friction head under the action of pressure and friction, which increases the friction resistance and improves the friction efficiency. The color fastness to dry rubbing of...

The outdoor fabric industry is customarily called water pressure resistance, and the unit is expressed in mmH2O, which means that the unit area bears the strength of water pressure. Under standard laboratory conditions, the fabric is subjected to the pressure of spraying distilled water up, and the maximum water pressure is recorded, such as water pressure 5000mmH2O. That is, the unit area can withstand a maximum pressure of 5m without leakage. Commonly used test standards: American standard AATCC 127; Japanese standard JIS L1092B; European standard: IS0 811; 1. Test before washing: Domestic outdoor brands generally test the water pressure resistance value before washing, but do not measure the value after washing. The water pressure resistance value drops greatly after washing several times, which may drop by about 1000-3000mmH2O; 2. Test after washing: Well-known outdoor brands in foreign countries usually test the water pressure after 5 times of washing, and even use the method of measuring the water pressure after 20 times of washing. Due to the test after multiple washings, the water pressure value drops very much. The test method is that any coating factory or lamination factory must use better materials for processing. For example, the water pressure resistance of the coated fabric must reach 5000mmH2O after 5 washings, then at least 7-8000mmH2O before washing; of course, this requirement will Lead to higher prices!

General The phenomenon of the fabric being pulled apart under such concentrated loads is often referred to as tearing. The tear strength of a fabric is an important indicator of the quality of textiles. The instrument used to measure this indicator is called Elmendorf Tearing Tester. Calculation principle: The tear strength measured by Elmendorf Tearing Tester was calculated from the work consumed when the sample was torn, and it can be said to be the average strength of the fabric tear. The work consumed during the tearing of the sample is the conversion of the potential energy of pendulum hammer. The potential energy consumed by the pendulum hammer before and after work can be divided into two parts: the work consumed during the tearing of the sample and the work consumed by all other resistances in the process. The work consumed for tearing the specimen is the product of the average tearing force and the work stroke; the work consumed by the resistance is the product of these resistance moments and the swing angle of the pendulum hammer. As shown in the figure, the solid line is the initial state, and the dotted line is the position at the end of the work. The formula for the principle of action is m g ( h1 - h2 ) = FS +Mα Or m gΔh = FS +Mα (1) In the formula: m--- Pendulum hammer mass, kg; g--- Gravity acceleration, m / s2 ; Δh--- Height difference of gravitational center of the pendulum hammer before and after work, m; F --- Average tearing force of sample, N; S --- work stroke of tearing the sample, m; M --- Resistance moment, N·m; α--- Pendulum hammer rotation angle. Machine recommendation: AG11 Elmendorf Tearing Tester It is used to measure the tear strength of materials such as fabric, paper, plastic cloth, film, electrical tape, and metal foil.

Jun 27, 2024The lasting vividness of clothing colors makes textiles visually attractive and expressive, so maintaining the color fastness of clothing is of vital importance. Color fastness refers to the ability of textile materials to maintain their original color under various conditions, including washing, friction, light, sweat, etc. Color fastness testing can help manufacturers screen and evaluate the quality and life of products. Good color fastness means that textiles are not easy to fade during post-processing or use; poor color fastness means that the color will fade, slightly discolor, or stain, causing a lot of trouble. Several common color fastness of textiles: 1. Light Fastness Sunlight fastness refers to the discoloration of colored fabrics under the influence of sunlight. It is mainly measured by simulating the fading degree of the sample after exposure to sunlight, and then comparing and rating it with the standard color sample to evaluate the quality of the fabric according to different grades. Fabrics with poor sunlight fastness should not be exposed to the sun for a long time. It is recommended to dry them in a ventilated place. 2. Sublimation fastness Sublimation fastness refers to the degree of sublimation that occurs when dyed fabrics are stored. Sublimation fastness uses a gray grading scale to assess the discoloration, fading, and staining of white cloth after dry heat pressing. There are 5 levels, with 1 being the worst and 5 being the best. Generally, 3-4 levels are required to meet the needs of wearing. 3. Rubbing Fastness Rubbing Fastness refers to the degree of color fading of dyed fabrics after rubbing, which can be divided into dry friction and wet friction. The degree of color fastness to friction is evaluated based on the degree of staining of white cloth. There are 5 levels in total. The larger the value, the better the rubbing fastness. 4. Perspiration fastness Perspiration fastness refers to the degree of color fading of dyed fabrics after being soaked in sweat. Since the composition of artificially prepared sweat is different, perspiration fastness is generally tested separately and combined with other color fastness. 5. Washing fastness Washing color fastness refers to the degree of color change of dyed fabrics after washing with detergent. Usually, a gray grading sample card is used as the evaluation standard, that is, the color difference between the original sample and the sample after fading is used for evaluation. Fabrics with poor washing fastness should be dry washed. If wet washing is performed, attention should be paid to the washing conditions, such as the washing temperature should not be too high and the washing time should not be too long.
