As consumers, if we just bought a piece of clothing and it fades seriously after washing it a few times, or the color is stained on other clothes after rubbing against other clothes, it will definitely be a very bad experience for consumers.
Therefore, color fastness is a key indicator in the production and quality control of textiles and is very important. As a powerful assistant for textile color fastness testing, AATCC Crockmeter plays an indispensable role in ensuring the quality of textiles.
1. What is AATCC Crockmeter?
AATCC Crockmeter is an instrument used to measure the amount of color transferred from the surface of a colored textile material to other surfaces through friction.
2. Working Principle of AATCC Crockmeter
The working principle of AATCC Crockmeter is to rub the colored test sample with a white friction test cloth under specific controlled conditions. After that, the color transferred to the white test cloth is evaluated by comparing with the gray grading card for dyeing or the color transfer grading table, and then the color fastness grade is determined.
3. Wide application scenarios
In the textile industry, AATCC Crockmeter is widely used from yarn production to final garment production. For yarn manufacturers, the test can help them understand the color stability of yarn after dyeing in the subsequent processing process, and avoid color problems in weaving and other links. For fabric manufacturers, color fastness is an important quality indicator for both ordinary woven fabrics and new functional fabrics. In the clothing production process, brand owners can use AATCC Crockmeter to conduct random inspections on purchased fabrics to ensure that the finished garments will not fade seriously during consumers' daily wear and washing.
4. Brief introduction to the operation process of Fabric Crockmeter:
- Sample preparation: First, cut two samples of at least 13×5cm in size, one for dry friction test and the other for wet friction test.
- Sample installation: Place the sample flat on the fixed position of the friction meter and fix the sample.
- Test: Shake the friction arm 10 times at a rate of once per second, and rub the friction arm back and forth 20 times
- Evaluation results: After the test, there may be some fibers stuck to the friction white cloth. At this time, these fibers need to be disposed of first to avoid affecting the evaluation. Then, place three layers of unused white rubbing cloth under the white rubbing cloth to be evaluated, and refer to the AATCC standard dyeing gray card to evaluate the dyeing grade of the white rubbing cloth. The evaluation of dry and wet friction fastness should be carried out on the two test results of the same sample.
AATCC Crockmeter plays a vital role in the field of textile color fastness testing. With its accurate test results, wide range of applications, simple operation process and reliable quality, it has become a powerful tool for quality control in the textile industry. For textile companies, making good use of AATCC Crockmeter, this powerful assistant, is to protect product quality and win more advantages for enterprises in market competition.
