Jan 16, 2025Experimental principle: It can detect the abrasion and pilling performance of various fabrics. Under a certain pressure, the sample and the specified abrasive are continuously rubbed against each other in a certain geometric pattern, and the abrasion and pilling degree are evaluated by comparing with the standard parameters. Touch screen control, equipped with a full-featured programmer, can pre-program batch and total counts, set the count of each test head separately; multiple speeds including standard speed can be selected. Experimental sample preparation: 1. Use a sampler to cut three specimens with a diameter of 38 mm from the sample. 2. Before testing, the specimens should be placed in an environment of 21±1℃ and 65±2% and humidified according to D1776. ASTM D4970 Martindale Abrasion Tester Experimental steps: 1. All test processes are completed under standard atmosphere. 2. Place a piece of 140mm diameter felt and 140mm standard friction cloth on each grinding table in turn, use a heavy hammer to flatten the friction cloth and felt (make sure there are no wrinkles, if it is not flat, repeat the above process), and fix the ring. (Fix the abrasive so that the warp and weft yarns of the woven fabric are parallel to the frame of the machine). 3. Clamp the sample with the sample clamp and make it face down. If the sample is lighter than 500g/m2, place 38mm polyurethane foam between the sample and the sample clamp. If the sample is heavier than 500g/m2, there is no need to place foam. 4. Place the sample clamp on the grinding table and apply the required pressure. For wearing fabrics, a pressure of 9±0.2kpa should be applied, and for decorative fabrics, a pressure of 12±0.3kpa should be applied. 5. The counter needs to be adjusted to zero, preset the appropriate number of times, and start the machine. 6. After the instrument stops, take out the sample to observe and evaluate its progress, estimate the number of times required to continue the experiment, and when approaching the end of the experiment, reduce the number of frictions between two inspections. It is necessary to carefully remove the hair particles produced by the sample during the test. 7. Experiment termination conditions: 1) Woven fabrics are worn until two or more yarns are broken, and knitted fabrics are worn until a hole is broken. 2) The experiment can be considered terminated when the color of the sample is worn away or its appearance is deformed, which will cause consumer complaints. 3) The experiment is terminated when the degree of color fading can be compared with the AATCC gray scale for color change to level 3. 4) It is determined by the percentage of mass loss before and after the sample is rubbed. 8. Record the number of frictions at the end of the experiment. Experimental report: 1. Reference standard, instrument model, experimental method and pressure used 2. Record the content according to the selected experimental termination conditions. 3. The average number of fr...

Dec 11, 2024In the production and inspection process of fabrics and garments, color fastness to rubbing is crucial to the service life of the fabric, the wearing experience of consumers and the appearance quality of the fabric. So what is color fastness to rubbing? The color fastness to rubbing refers to the color loss of the rubbed part of the textile when it is rubbed under a certain pressure. The color fastness to rubbing test is to check the degree of staining of the cotton cloth after rubbing the surface of the fabric a certain number of times with dry or wet white cotton cloth, and then rate it with the gray sample card for staining assessment. Common standards for color fastness to rubbing include GB/T 3920-2008, AATCC 8-2007, AATCC 116-2010 and JIS L 0849-2004. The classification of color fastness to rubbing is based on the degree of staining of white cotton cloth after rubbing: These standards divide color fastness to rubbing into 9 levels from 1 to 5: Level 5: Best. After rubbing, there is almost no color staining on the white cotton cloth, indicating that the sample's color fastness to rubbing is very good. Level 4: Good. There is slight color staining on the white cotton cloth, but it does not affect the overall appearance. Level 3: Average. There is obvious color staining on the white cotton cloth, but the color distribution is relatively uniform. Level 2: Poor. There is obvious color staining on the white cotton cloth, and the color distribution is uneven, which may affect the overall appearance of the sample. Level 1: Worst. There is serious color staining on the white cotton cloth, and the color distribution is extremely uneven, indicating that the sample's color fastness to rubbing is very poor. However, in the test of color fastness to rubbing, due to irregular weaving or uneven dyeing of the fabric, it is easy to cause inconsistent results after multiple frictions, which is accidental. It is necessary to take multiple measurements to obtain a specific report with a high repeatability result.

Nov 22, 2024The shrinkage rate of textile fabrics varies depending on the specific type. The fabrics with the smallest shrinkage rate are synthetic fibers and blended fabrics, while the fabrics with the largest shrinkage rate are synthetic cotton, synthetic wool fabrics, and viscose fibers. The shrinkage rate of some fabrics is as follows: No. Type Shrinkage 1 Cotton 4%--10% 2 Chemical fiber 4%--8% 3 Cotton and polyester 3.5%--5.5% 4 Natural white cloth 3% 5 Blue nankeen 3-4% 6 Poplin 3-4.5% 7 Cotton print 3-3.5% 8 Twill 4% 9 Denim 10% 10 Artificial cotton 10% Reasons affecting shrinkage rate: 1. Differences in fabric density Different fabric densities can lead to varying shrinkage rates. Textiles with high warp density tend to experience greater shrinkage in the warp direction, while fabrics with higher weft density tend to experience greater shrinkage in the weft direction. 2. Differences in fabric raw materials Different fabric raw materials can lead to varying shrinkage rates. In general, materials with high moisture absorption have a higher shrinkage rate, while synthetic fiber fabrics with poor moisture absorption have a lower shrinkage rate. 3. Differences in fabric production processes The different production processes of fabrics can lead to different shrinkage rates. During the weaving and dyeing process of fabrics, the fibers need to be stretched multiple times, and the processing time is long. The shrinkage rate of fabrics with high tension is higher. 4. Differences in production and processing processes The differences in production and processing processes can lead to varying shrinkage rates. Because fabrics are stretched by production machines during dyeing, printing, and finishing processes, tension is generated on the fabric. However, when the fabric comes into contact with water, the tension is easily relieved. Therefore, in actual production processes, pre shrinkage is generally used to address this issue. 5. Differences in fabric structure Different fabric structures can lead to varying shrinkage rates. The stability of knitted fabrics is inferior to the dimensional stability of woven fabrics. 6. Differences in yarn count thickness of fabrics The different thickness of fabric yarn can lead to different shrinkage rates. Generally, fabrics with thicker yarn count have a higher shrinkage rate. 7. Impact of washing and care process The washing and care process can affect the shrinkage rate of the fabric. During the washing, drying, and ironing processes, each step can affect the shrinkage of the fabric. Usually, the higher the temperature, the poorer the stability. Additionally, selecting an appropriate ironing temperature based on the composition of the fabric can also improve its shrinkage. 8. Differences in fiber composition The difference in fiber composition can lead to different shrinkage rates. Compared with synthetic fibers such as polyester, plant regenerated fibers such as viscose and natural plant fibers such as cotton and linen ar...
Nov 18, 2024Clothes may be damaged to varying degrees during the washing process, such as the following situations. These situations can remind everyone to control the production process to avoid similar situations. 1. Changes in printed clothes after washing: Color bleeding, Fading, Loss of print integrity, Rubber deformation & aging 2. Fabric color transfer after washing During the washing process, fabrics of different colors penetrate each other, causing color confusion and color blending. This usually happens more often with clothes with sharp color contrasts. For example, the following situations all show obvious color blending after washing. 3. Clothes with accessories are also prone to varying degrees of damage after washing: 1) Accessory damage • Deformation • Fading • Surface wear 2) Problems with the connection between accessories and clothing • Looseness • Falling off 3) Problems with the garment itself • Deformation • Stain transfer or stain transfer These situations are the nodes that fabric and clothing manufacturers need to focus on during the production process. Therefore, relevant testing instruments are needed to analyze textile fabrics and screen out high-quality fabrics to serve the market. 1. Automatic Wascator Shrinkage Tester AC13 2.
