Mastering Material Testing: The Essential Guide to Coefficient of Friction

 

The coefficient of friction tester is a measuring instrument used to measure the static and dynamic friction coefficients of materials such as plastic films and sheets, rubber, paper, cardboard, woven bags, fabric styles, metal composite belts for communication cables and optical cables, conveyor belts, wood, coatings, brake pads, wipers, shoe materials, tires, etc. when sliding. By measuring the smoothness of materials, the production quality and process indicators of materials can be controlled and adjusted to meet the requirements of product use. In addition, it can also be used for measuring the smoothness performance of daily chemical products such as cosmetics and eye drops.

Related definition

Antistatic: Property of a material that reduces its propensity to acquire electrostatic charges or allows electrostatic charges to dissipate quickly.
Conductive: Providing a sufficiently high conductivity so that potential differences over any parts of a material or object are not sufficiently large to be of practical significance.
Note: In general, a conductive material has a resistance below about 105 Ω, but different standards may define different resistance ranges for this term.
Frictional charge density: Quantity of charge per unit area on a fabric specimen generated by friction between the specimen and other fabrics.
Electronic charge: The charge carried by the specimen after friction with the standard cloth for a certain period of time.
Note: For non durable anti-static textiles, the pre washing charge should not exceed 0.6 μC per piece; For durable anti-static textiles, the charge before and after washing should not exceed 0.6 μC per piece.

Twist Test Methods and Influencing Factors

Image
  Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To understand twist testing, you must first understand what twisting is. Twisting is a necessary condition for yarn formation. Short fibers can be made into yarns with certain physical and mechanical properties through twisting; filaments often need to be twisted in order to increase the tightness between single filaments, facilitate processing, and improve fabric properties. Number of twists Twisting is to cause two cross-sections of parallel straight fiber slivers to rotate relative to each other. The number of relative rotations of the two cross-sections is called the number of twists. Twist Twist refers to the number of twists per unit length of yarn . Twist coefficient In actual production, the twist coefficient is of

Combing Process in Spinning

Image
Before processing cotton, wool, and silk fibers into fabrics, the process of removing impurities and short fibers in the fibers with a combing machine is called combing. The texture, washability and durability of the fabric produced through this process are greatly improved compared with carded fabrics. The following introduces the composition of the combing machine and the combing process. The kinematic coordination relationship of the main parts on the combing machine is indicated by a dial. The disc is mounted on the combing machine and rotates synchronously with the cylinder, which is generally called the indexing disc. The index plate is divided into 40 equal parts along the circumference, and each equal part is 9°, which becomes one index. The working cycle refers to the time interval between the combing cylinder of the intermittent combing machine corresponding to the two actions of combing the whiskers. That is: the first row of needles in the combing cylinder goes to the botto

Garment Dyeing-Special Dyeing Method In Textile

Image
Garment dyeing is a relatively special dyeing process for textiles and garments. Many people may not know much about this dyeing process. In the impression of most people, textile and clothing products are dyed in the fabric period, and garment dyeing is a dyeing process that breaks people’s cognitive limitations on textile dyeing. ​What is garment dyeing ​Garment dyeing means that dyeing the one not in the fabric type but in the garment type itself. The garment type mentioned above include socks, towels, sportswear, shirts, plush toys (without fillers), T-shirts, pants, bathrobes, handkerchiefs, bath mats, carpets, scarves, etc. The material of these garments can be wool, linen, silk and cotton of natural fibers. But most garments are made of cotton or a cotton-rich blends. Garment dyeing imparts vibrant colors to garments. The clothes such as denim garments, tops, sportswear and casual clothing with garment dyeing can provide a distinctive special effect. Garment dyeing method Garmen
