Analysis of hygroscopicity characteristics of sampling apocynum by fiber analyzer

Apocynum fiber is one of the new plant fibers. From the discovery of apocynum fiber to the present, it has always been concerned by the textile industry. Apocynum fiber is a bast fiber located within the phloem tissue of the stem. In addition to the common properties of bast fiber, such as moisture absorption and air permeability, it also has the function of antibacterial and health care. Sampling and measuring the content through the fiber tester and researching the performance of the refined apocynum fiber can provide scientific basis for the research and development of textile products.

Hygroscopicity of fibers is usually expressed in terms of water content and moisture regain, and the fiber tester tests the moisture regain of lyophobic fibers by an oven method. The fiber to be tested taken by the fiber tester was placed under laboratory conditions for 24 hours, and then accurately weighed 3 parts, each weighing 4~5g, placed in an electric constant temperature drying oven at 105±2°C and baked to a constant weight. (The weight difference between two consecutive times does not exceed 0.05% of the last time), and the test result is 16.2%. Compared with 13.1% of ramie fiber and 8.6% of cotton fiber, lean apocynum fiber has better hygroscopicity.

The intensive apocynum fiber has higher breaking strength and smaller elongation at break, which indicates that the fiber is high-strength and low-extension fiber, and the fiber is brittle. The friction coefficient of a certain amount of quiescent apocynum fiber measured by a fiber tester is approximately 0.3 to 0.45, and the static and dynamic friction coefficients are not significantly different. In the fiber tester test, it was also found that the surface of the sturdy apocynum fiber was relatively smooth, indicating that the cohesion between the sturdy apocynum fibers was not ideal. In particular, the length of the fibers is very different, which brings certain difficulties to the spinning of the fibers.

Therefore, in the development of refined apocynum fiber products, blended products are generally used to develop products by combining the characteristics of other blended fibers. The surface quality specific specific resistance of the dried apocynaceae fiber used for the fiber tester is smaller than that of the cotton fiber. This shows that lean apocynum fibers have higher antistatic capacity than cotton fibers. The good anti-static property makes the sturdy apocynaceae fiber products not easy to adhere to the body while wearing, and it is also not easy to adhere to dust and has good taking performance.
