    How to test the mutual color fastness of textile splicing

    17 Aug, 2022

    Clothes stained during washing or soaking? I believe that everyone is familiar with this situation, and many people should have encountered such embarrassing things. This is due to the mixed washing of dark and light-colored clothes, the fading of dark-colored clothes and dyeing on light-colored clothes, resulting in staining of light-colored clothes, or the mutual staining of dark and light colors on a piece of clothing after washing. In response to this phenomenon, there is a professional name in textiles: splicing and mutual dyeing. Test methods for testing the interdyeing of textiles by splicing, namely the washing method and the soaking method. The washing method The sample is placed in the specified washing solution, mechanically stirred according to the specified bath ratio, time and temperature, then washed and dried, and the staining of the light-colored sample is evaluated with a staining gray card or an instrument. The soaking method The sample is placed in the specified washing solution, and after treatment, it is placed between two flat plates with a specified pressure in the test device. After cleaning and drying, the staining of the light-colored sample is evaluated with Gray scale for color staining or an instrument. Sample preparation: 1. The sample is a ready-made garment. Cut a piece of dark and light-colored fabrics, 4×10cm, and sew them along the short side to form a combined sample. 2. Weigh the sample to the nearest 0.01g. 3. Add detergent according to the sample weight. The sampling and soap solution configuration of the two methods are the same, the only difference is the test equipment and operating procedures. Test Instruments The washing method: Wash Colour Fastness Tester The soaking method: Precision Drying Oven Operating procedure The washing method 1. Put the sample and test solution into the container 2. Put the container into the machine, set the temperature to 40 degrees, and test it for 30 minutes. 3.

    Knowledge Sharing: Measures to Reduce Pilling

    31 Jul, 2022

    In the process of wearing and using fabrics, different degrees of pilling will occur. So how can we reduce the pilling of our fabrics? Spinning process During the spinning process, the fibers in the twisting triangle area undergo repeated internal and external transfer due to uneven force, causing the head end, tail end or middle part of most fibers to protrude from the yarn body, forming hairiness. In order to reduce the hairiness, the textile mill rationally mixes cotton, optimizes the process, adopts advanced textile technology according to its own conditions, and tries to control the occurrence of hairiness within the scope of its ability. Weaving process The organizational structure of knitted fabrics has a great influence on pilling, and the tight organization is less prone to pilling than the loose organization. Dyeing and finishing process Singeing: Singeing is a great way to reduce hairiness and reduce pilling. Adjustment of technical parameters: After the dyeing and finishing technology is determined, parameters such as bath ratio time can be adjusted appropriately, for example, the bath ratio can be appropriately increased or the technical curve can be improved to shorten the time. Use of auxiliaries: Anti-pilling agents can be added during the bleaching process. The softener is added during the dyeing process to reduce the mixed friction between the yarns and between the fabric and the dyeing machine, and at the same time, it can control the leakage of the fibers from the end of the yarn, thereby reducing the chance of pilling. Hairiness appressing method: The hairiness appressing method is to use mechanical and physical and chemical methods to make the hairiness tightly adhere to the surface of the fabric, so as to reduce feathers and reduce pilling. Specifically, the use of resin auxiliaries or chemical adhesives, through rolling, makes the hairiness lodged and fixed on the surface of the yarn. Through the above methods, the pilling can be improved to a certain extent. Reducing pilling is a systematic project, and it is recommended to take comprehensive measures in the production process of fiber production, spinning, weaving, dyeing and finishing.

  • Classification of woven fabrics

    Classification of woven fabrics

    17 Jun, 2022

    Fabrics are products made of yarn (thread) or fiber, mainly including woven fabrics, knitted fabrics and nonwoven fabrics. Woven fabrics are products made of two groups of mutually perpendicular yarns (threads) interwoven on the loom, such as common plain cloth, gabardine, khaki, satin, etc. The yarn arranged along the length of the fabric is called warp, and the yarn arranged along the width of the fabric is called weft. By changing the raw materials, thickness and organizational structure of the yarn or using different colored yarns to cooperate with each other, different warp and weft yarns are interwoven with each other, and fabrics of different styles and uses can be woven. These fabrics can be divided into clothing fabrics, decorative fabrics and industrial fabrics. A. Classification of woven fabrics for clothing Woven fabrics for clothing are usually classified according to whether the raw material yarn is dyed or not, fabric pattern and width. 1. According to the type of raw materials (1) Pure textile fabrics: The warp and weft yarns are all fabrics made of the same fiber raw material, such as cotton fabrics, linen fabrics, wool fabrics, silk fabrics, etc. (2) Blended fabric: warp and weft yarns are fabrics made of yarns mixed with two or more fibers, such as polyester / cotton fabrics, wool / polyester fabrics, polyester / linen fabrics, wool / polyester / nitrile fabrics and medium length fabrics. (3) Interwoven fabrics: fabrics made of different raw material yarns for warp and weft, such as silk-wool interlacing, cotton and viscose filament interlacing, silk and viscose filament interlacing and other interwoven fabrics. (4) Interlaced fabric: The warp and weft yarns are woven from two or more different raw materials combined with synthetic strands. 2. Classification according to whether the yarn is dyed or not (1) Natural color fabric: the yarn is processed into fabric without bleaching and dyeing, which is directly sold or processed into finished products after dyeing and printing. (2) Yarn dyed fabric: a fabric made of bleached and dyed yarn. 3. Classification by fabric pattern (1) Plain fabrics: fabrics without patterns, such as various plain fabrics, twill fabrics, satin fabrics, etc. (2) Small patterned fabric: the pattern fabric with small area is formed on the fabric through the change of fabric structure, such as various tweeds. (3) Jacquard fabrics: fabrics with a wide range of patterns formed by controlling a single warp, such as floral satin. 4. According to the width of fabric, it can be divided into wide fabric, narrow fabric and belt fabric. B. Classification of decorative woven fabrics Decorative fabrics are available in a wide variety, usually divided by application.

  • Do you know what factors affect the color fastness of textiles

    Do you know what factors affect the color fastness of textiles

    29 Apr, 2022

    The color fastness of textiles (hereinafter referred to as color fastness) refers to the fading process of dyed or printed fabrics under the action of external factors (extrusion, friction, washing, rain, exposure, light, seawater immersion, saliva immersion, water stain, sweat stain, etc.) in the process of use or processing. It is an important index of fabrics. Good color fastness, textiles are not easy to fade in the process of post-processing or use; If the color fastness is poor, there will be color fading or staining, resulting in a lot of trouble. The most common textile color fastness problems: Unqualified fastness to sunlight: during the wearing process of coats and clothing, the color of the parts exposed to more sunlight becomes lighter or discolored (generally the back and shoulder), while the color of the parts not exposed or less exposed remains unchanged or changes slightly, resulting in different colors of the products with the same original color, which can no longer be used. Our company detects light fastness related machines: 1. AC01 Light Fastness Tester (air-cool) 2. AC02 Light Fastness Tester (water-cool) Unqualified color fastness to washing, soaping and dry cleaning: clothes fade after washing. Silk clothing, wool clothing and pure cotton clothing are most prone to such problems. Our company detects color fastness to washing and other related machines: AC10 Water Colour Fastness Tester Unqualified color fastness to rubbing: in the process of using textiles, because different parts of the product are subject to different degrees of rubbing, the degree of fading is different. For example, the elbows, collars and armpits of coats and sleeves are most likely to fade. In addition, the buttocks and knees of trousers are also easy to fade. Our company detects the color fastness to rubbing related machines: AATCC Crockmeter: AC04, AC04-2, AC04-3, AC05, AC05B The color fastness to perspiration is unqualified: mainly when summer clothes or close-fitting underwear are worn, the color will fade due to perspiration impregnation. Our company detects the color fastness of perspiration related machines: AC08 Perspiration Tester Factors affecting the color fastness of textiles: There are many factors affecting the color fastness of dyed products, but it mainly depends on the chemical structure of the dye, the physical state of the dye on the fiber (the degree of dispersion of the dye, the combination with the fiber), the concentration of the dye, the dyeing method and process conditions, etc.; The nature of the dye is also closely related to the color fastness.

Laboratory equipment managers should be familiar with the working principle of each instrument and understand the functionality and working mode of each component of each instrument and equipment, so as to formulate maintenance contents for the functional components of the instrument. Generally, the common maintenance contents are as follows: 1. Check the appearance and operation of functional components 2. Cleaning 3. Add lubricating oil, antirust oil, etc 4. Replace consumables / accessories General principles for selecting maintenance intervals and times Equipment maintenance is aimed at all the instruments in the laboratory: 1. Determine the frequency of the cycle according to the working principle of the instrument and the frequency of use; 2. Appropriately relax or shorten the maintenance cycle according to the harsh environment of the equipment; 3. Cooperate with the equipment period inspection. Generally speaking, equipment maintenance should be arranged before each equipment period inspection to ensure that the equipment is in the best condition during the period inspection. The routine maintenance of general equipment can be controlled at about twice a year. Under special circumstances or special equipment, flexible maintenance shall be carried out according to the specific actual situation: 1. The equipment with periodic replacement of consumables shall flexibly grasp the cycle according to the specific replacement cycle; 2. For the equipment working in the unavoidable harsh environment, the maintenance times shall be appropriately increased according to the actual situation without affecting the test; 3. It is recommended to arrange a maintenance before the equipment is checked during the period; 4. For equipment with high frequency of use, the number of maintenance shall be appropriately increased. Routine maintenance of common laboratory testing instruments 1. ICI Pilling and Snagging Tester Regularly wipe the surface of the cork liner with a trace amount of methanol, clean the roller box before and after the test, check whether the cork liner falls off and whether there are sharp objects on the surface, and regularly clean the exposed parts of the rotating shaft and bearings to prevent fiber residues and yarn residues. On the bearing, the rotation of the roller box is stuck and the rotation speed is abnormal. After confirming that there is no residue on the rotating shaft and the bearing, add lubricating oil.
