Quilt cotton yarn production lines and various chemically spun and blended yarns choose different gauge levels, because one or more processes (and) different purposes even cotton yarns, in choosing not exactly the same level of gauge, the required spun yarn flat to come Controls the respective canonical IDs. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
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. 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.
This section will mainly describe the classification of cotton yarns, as well as the classification of purified fiber and blended yarn properties. They are only descriptions. Quilt and Cotton Yarn Production Line Classification (-) Types of Cotton Yarns The types and codes of commonly used cotton yarns are shown in Table 7-10. In the yarn production process in the above code, the code used is after.
1. After drying and re-moisturizing, the skeins after the strong pull are weighed outside the oven, and then they can be put into the supply oven for drying. The dry weight is weighed in the oven, and it is baked until the characteristic component remains unchanged (the difference in the development of the two-pass weighing at an interval of 10 minutes does not exceed 0.05% of the original weighing cocoon). You must not grasp the tide of Kou Shiba by yourself.
2. The cotton yarn products of grade 2 have been identified by the quality target, and the composition is uneven, with excellent, first-class and second-class, and non-conforming second-class is classified as third-class. When the quality target and the unevenness of the components are different from the products evaluated after comparing with the national standard, they shall be identified as medium and low products. If the component error exceeds the promised scale, it will be regarded as non-standard, and on the basis of the original evaluation, it will be dealt with at Level 1, but it will be stopped when it is reduced to Level 3.
