Testing the viscosity of cotton fiber mainly uses the method of developing machinery, which mainly includes testing method by hot plate, micro-carding machine method, circulating roller method, etc. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.
The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Today, I will explain and analyze in detail a micro-carding machine method. The micro-carding method is a method used to detect small cards in the spinning processing system with small cotton fiber stickiness.
Environmental development conditions can be controlled within 24°soil 1°, the relative high humidity is 55% ± 2%, and the cotton material is made into a cotton web with a certain size and then processed by the carding machine. The sample needs to pass through the carding machine. It takes 1-3mino. This teaching method is based on whether the input The passed cotton web was assessed for the stickiness of the cotton fibers by characterization of the reel using stainless steel, and it was designed into 5 grades. 0—no stickiness; 1—light user stickiness; 2—moderate stickiness; 3—severe stickiness; 4—polarity and severe stickiness. The rating of these five grades is influenced by five factors: (1) the number of occurrences of stickiness; (2) the size of the stick; (3) the tendency of cotton to stick; (4) the time of occurrence and enhancement of stickiness (5) Sticky deposits and wool remaining on the reel after the detected amount.
In 1988, the Honeydew Task Force meeting of the International Textile Processing Technology Association (ITMF) concluded that this teaching method is the best way to measure cotton honeydew. However, this learning method has shortcomings such as large error, strong subjectivity, and few samples for testing and analyzing results.
