Description

Production device and production method of differentiated functional fiber color spinning strips

Technical Field

The invention relates to the new technical field of spinning, in particular to a device and a method for producing a fiber color spinning strip with a differentiation function.

Background

In recent years, the aspects of the traditional spinning industry are deeply changed, which is remarkably reflected in the aspects of equipment automation, continuity, intellectualization, high-speed and high-efficiency, low energy consumption and the like, and promotes the transfer of products to quality and diversity. Automated spinning process equipment is in widespread use, with the pace of "robot change". The continuous spinning technology is adopted, so that the traditional spinning process is shortened, and the method is an important way for realizing robot replacement and reducing labor. By adopting an intelligent technology, the traditional spinning production is developed to an online automatic monitoring direction. Along with the development of technology, particularly the popularization and application of intelligent technology and the progress of the manufacturing technology of spinning key equipment, good conditions are created for the spinning equipment to realize high-speed operation.

Drawing is one of important links in spinning process, and the drawing frame has the functions of improving the internal structure of the sliver, raising the uniformity of long section, reducing uneven weight, making the fiber in the sliver straight and parallel, reducing hooks, making fineness meet the requirement, and mixing different kinds of material homogeneously to reach the required mixing ratio. Since the 18 th century invention roller draft and applied to spinning frames and roving frames, the required uniformity of the product is not achieved due to the uneven addition of the roller draft to the yarn, and two or more slivers are combined to improve the uniformity, so that an initial drawing frame appears. The drawing frame is changed from increasing drawing to double-zone drawing and from straight drawing to curve drawing, so that the quality of the produced sliver is obviously improved and the shrinkage is realized. The output speed of drawing frames has increased rapidly from 40 to 60 meters per minute to over 200 meters per minute, even up to 600 meters per minute since the 50 s of the 20 th century. At present, the high speed of drawing frames and the diversification of products are the main directions of development. The segment colored yarn and even the colorful yarn are fancy yarns with different color distribution, the structure is very characterized, and the fancy yarn can be combined with other novel spinning modes, and the manufactured fabric has unique appearance and performance, thereby meeting the yarn-using requirements of new and different fabric and clothing. The colorful yarn is widely applied to clothing, decorative articles and the like, is more and more favored by people, and has strong competitive power and development value in the market. The segment color yarn can be directly produced on a spinning frame, and can also be carried out in the previous process of spinning, for example, the drawing process of mixing various slivers is realized.
