What is the light fastness Color fastness to light, also known as light fastness, refers to textiles that are usually exposed to light during use. Light can destroy dyes and cause the well-known "fading", which makes colored textiles discolored, generally lighter and darker. What is the color fastness to light machine test principle The textile and a set of blue wool standard samples are exposed to artificial light sources under specified conditions, and then the color change of the sample is compared with the blue wool standard sample to evaluate the color fastness. What is the color fastness to light machine test standard At present, there are mainly three commonly used standards for testing light fastness: GB/T 8427, ISO 105-B02, AATCC 16.3. GESTER Instrument: Light Fastness Testing Machine GT-D02A-1 Factors affecting light fastness The main factors that affect the fading of the sun include light, the molecular structure of the dye, the focus state of the dye, the depth of dyeing, the color matching of the dye, the auxiliaries required for the dyeing process, the characteristics of the fiber, and the locality. Methods to improve color fastness to light 1. The choice of dyes: dyes with high light fastness are preferred, which can prevent or reduce the occurrence of photooxidation reactions; 2. In the color matching of dyes, select component dyes with equivalent light fastness to ensure the light fastness level; 3. The fixing agent has a close relationship with the light fastness of the dye. The use of non-surfactant ammonium salt type fixing agent and reactive fixing agent can effectively improve the light fastness. Main products: nylon, cotton and light color, fluorescent color products.

First of all, let’s talk about the color fastness test to washing. The washing fastness tester is also called the color fastness to washing, or the color fastness to soaping. It is used to assess the color fade and the color of the original fabric during the soap washing process. Staining the lining. The principle of the test is to sew textile samples with one or two specified standard lining fabrics, place them in soap or soap and anhydrous carbon-sodium mixture, perform mechanical agitation under specified time and temperature conditions, and then After cleaning and drying. Use the original sample as a reference sample, and use a gray sample card or instrument to evaluate the discoloration of the sample and the staining grade of the lining fabric. Secondly, what we want to talk about is the water fastness test. The so-called water fastness is also called the water stain fastness, which is to assess the discoloration of the original fabric and the staining of the lining after the fabric is soaked in water. The principle of the test is to sew a textile sample with one or two specified standard lining fabrics, immerse it in water, squeeze out the water, and place it in the middle of the two plates of the test device under specified pressure. After a certain period of time, take it out The sample and the lining fabric are dried, the original sample is used as the reference sample, and the gray sample card or instrument is used to evaluate the discoloration of the sample and the staining grade of the lining fabric. The color fastness to washing test can use the GT-D07 color fastness tester produced by GESTER Company, which is controlled by LCD counter display, and the composite cup mode can be customized according to customer requirements. It conforms to ISO, BS, AATCC, JIS and SDC And other standards. The color fastness to water test can choose the GT-D09 perspiration tester, stainless steel test frame and weights produced by our company, which is durable.

Color fastness is also called color fastness and dyeing fastness. It refers to the resistance of the color of textiles to various effects during processing and use. The fastness grade is evaluated according to the discoloration of the sample and the staining of the undyed lining fabric. Textile color fastness test is a routine test item in the internal quality test of textiles. During its use, textiles will be exposed to various external effects such as light, washing, ironing, perspiration, friction and chemical agents. Some printed and dyed textiles are also subjected to special finishing processes, such as resin finishing, flame retardant finishing, sand washing, and grinding. This requires the color of printed and dyed textiles to maintain a certain degree of fastness. Color fastness test items Washing color fastness: The sample is sewn together with the standard lining fabric, washed, washed and dried, and washed under suitable temperature, alkalinity, bleaching and friction conditions, so that the test results can be obtained in a short time .Use machine: color fastness to washing GT-D07 Color fastness to dry cleaning: Same as color fastness to washing, except that washing is changed to dry cleaning.Use GESTER machine:Dry Cleaning And Washing Cylinder GT-C36 Color fastness to rubbing: Put the sample on the rubbing fastness meter, rub it with a standard white cloth under a certain pressure for a certain number of times. Each group of samples needs to be dry rubbing color fastness and wet rubbing color fastness. The color stained on the standard rubbing white cloth is graded with a gray card, and the grade obtained is the measured rubbing color fastness. The color fastness to rubbing needs to be tested for dry rubbing and wet rubbing. All the colors on the sample must be rubbed. Use machine: Electronic Crockmeter GT-D04 Light fastness: Textiles are usually exposed to light when they are in use. Light can destroy dyes and cause the well-known "fading", which makes colored textiles lighter and darker, and some color changes will also occur. , It is necessary to test the color fastness. The light fastness test is to put the sample and blue wool standard cloth of different fastness grades together under the specified conditions for sunlight exposure, and the sample and the blue wool The cloth is compared to evaluate the light fastness. The higher the blue wool standard cloth, the better the light fastness. Use machine: Air-Cooled Light Fastness Tester GT-D02A-1 Color fastness to perspiration: sew the sample together with the standard lining fabric, put it in a sweat solution, and place it on the perspiration fastness tester, put it in an oven at a constant temperature, then dry, and grade it with a gray card. Get the test results. Different test methods have different perspiration liquid ratios, different sample sizes, and different test temperatures and times. Use GESTER machine:Perspiration Tester GT-D09 Color fastness to water stains: Test as ...
