Yarn is a kind of textile, which is processed into fineness products with all kinds of textile fibers. It is used for weaving, rope making, thread making, knitting and embroidery, etc. The quality of yarn in the production process has a profound impact on the interests of factories and enterprises. Therefore, it is necessary to test the quality of yarn to determine it's grade. Alfa Chemistry Testing Lab, which provides yarn testing services and global recognition of test reports, and supports global code scanning to query the authenticity. Alfa Chemistry Testing Lab has complete testing qualifications, advanced laboratory instruments, and a strong scientific research team. It has always served customers with the spirit of R & D contribution, and provides customers with scientific experimental solutions and strong technical support.
Analysis items: component analysis, unknown object analysis, material identification, failure diagnosis analysis, comparative analysis, material thermal analysis, qualitative and quantitative analysis, return material analysis, etc.;
Routine testing: quality, content, tension, count, defect, fracture (breaking strength and elongation at break of single yarn), density (linear density, bulk density), strength, moisture content, oil content, twist, color fastness, etc.
Instrument | Application |
---|---|
Automatic Single Yarn Strength Tester | It is used to test the physical indexes of single yarn, such as breaking strength, elongation at break, breaking time, initial modulus, breaking work, etc. |
Yarn Twist Tester | It is used for measuring twist of various cotton, wool, silk, chemical fiber and other yarns, rovings and strands. |
Yarn Length Meter | It is used to calculate the linear density of yarns or chemical filaments |
Strip Rough Length Measuring Machine | It is used to shake sliver and roving of cotton, wool and silk to form a certain length to measure its evenness. |
Rocking Blackboard Machine | It is used to shake the yarn of specified density on the blackboard to grade the appearance quality of the yarn. |
Cotton Roll Uniformity Machine | It is used to determine the uniformity and actual length between segments of one meter length of cotton rolls, and to determine the weight and elongation of cotton rolls at the same time. |
Sliver and Roving Length Meter | Used to test the evenness of sliver and roving of cotton, wool, hemp, silk, silk, etc. |
Ventilated Fast Eight-basket Oven | It is the standard oven to test the moisture content and moisture regain of all kinds of textile materials and productions. |
ICS-3102 Electronic Balance | Used to calculate the gram weight of yarns, textiles, woven bags, fabrics and other samples. |
