Characteristics of rubber 1. Natural rubber: raw rubber material made by cutting the rubber trunk, collecting the flowing rubber slurry, removing impurities, curing, smoking and drying.
2. Synthetic rubber: by-products of petrochemical industry synthesize raw rubber with different physical properties according to different needs. Common users such as SBR, NBR, EPDM, BR, IIR, CR, Q, FKM, etc. However, due to different synthesis methods, several different kinds of raw rubber can be separated from the same rubber compound, and any type of rubber compound can be turned into thousands of raw rubber to meet the needs of products through the setting of formula. 3. The characteristic yarn of fiber is made of fiber polymerization and twisting, and then these yarns are made into woven cloth and card clothing. The structure of fiber will affect the performance characteristics of fabric, and the physical characteristics, chemical composition and molecular composition of fiber also determine the characteristics of fabric. fibre length
The fiber whose length can be measured is called short fiber, and the fiber whose length is infinite is called long fiber. For short fibers, the longer the fiber length, the higher the yarn quality.
Cross-sectional shape and surface shape
It determines the volume, texture, luster and feel of the fiber. For example, circular fibers are not as easy to compress as flat fibers, and the fabrics made are bulky and smooth. honest
Fibers can be straight, twisted or curled, and the characteristics of longitudinal section will affect the resilience, elasticity and wear resistance of fibers. For example, crimped fibers help to increase elasticity, bulkiness, warmth retention, elongation and absorption capacity. force
