Description

technical field [0001] The invention relates to a fibril preparation process and a PET fiber prepared by the process, belonging to the technical field of chemical fibers. Background technique [0002] At present, PET fiber is mainly used in the textile industry and is the largest variety of synthetic fiber; the biggest advantage of PET fiber is that it has good wrinkle resistance and shape retention, high strength and elastic recovery ability, and it is durable, Anti-wrinkle, non-ironing, non-sticky hair, so it has a wide range of applications. However, the conventional PET fiber has a single color and lacks functional application effects, thus restricting its development; [0003] In today's PET fiber production process, the following problems are found: [0004] First, the manual batching method is adopted in the conventional PET fiber production process, that is, the material is piled up in the discharge hopper used for extrusion after manual heavy work. The ratio betw...

AI Technical Summary

Problems solved by technology

[0004] First, the manual batching method is adopted in the conventional PET fiber production process, that is, the material is piled up in the discharge hopper used for extrusion after manual heavy work. The ratio between them is not accurate enough, which affects the quality of the product; at the same time, manual methods cannot screen the raw materials to remove impurities, so foreign materials will be introduced, which not only reduces the quality of the product, but also the color of the foreign materials is different from that of normal raw materials. , therefore, it will have a considerable impact on the color and appearance of the finished product, thereby reducing the quality of the product, which is not conducive to improving the market competitiveness of the enterprise

[0005] Second, in the conventional PET fiber production process, there is a lack of a color masterbatch quantitative addition device, so it is impossible to produce colored fibers, and the conventional PET fiber lacks a filtering mechanism during the heating and extrusion process, and cannot effectively filter out impurities in the molten raw material. Therefore, the quality of subsequent products is poor, which is not conducive to improving the quality of production;

[0006] Third, the extraction mechanism in the conventional PET fiber production process lacks the function of wire break detection. When the wire breaks, it cannot report to the police in time. Therefore, it is necessary to arrange inspection personnel to conduct regular inspections. It takes time to find out the disconnection, which affects the continuity of production and is not conducive to increasing the output; in addition, the cluster device equipped on the conventional extraction mechanism is a simple ring structure, which has a single function and poor clustering effect;

[0007] Fourth, conventional PET fibers are simply dropped into the cluster barrel for collection during the tow collection process. In actual use, it is found that manual intervention is required, otherwise the directly dropped tow cannot be flattened and filled. The entire cluster barrel, thereby reducing the utilization rate of the cluster barrel;

[0008] Fifth, conventional PET fibers lack anti-static effects, so they cannot be used in some occasions that require anti-static properties, such as in electronic equipment installation workshops (static electricity is easy to break down electronic components), and clothing and other items made of PET fibers Without the anti-static function, it is easy to generate static electricity and cause electric shock to the human body. Although the electric shock damage is negligible, the wearing experience is poor;

[0009] Sixth, in the cutting process of conventional PET fibers, due to the need to install the blade on the blade holder, and then install the blade holder in the support, the cut filament enters the support through the gap between the blades and falls to achieve Continuous production, in which the distance between the blades determines the length of the filament. Due to the existence of the blade holder, the distance between adjacent blades is relatively large, so it is impossible to produce ultra-short fibers, which restricts the development of enterprises;

[0010] Seventh, the unloading mechanism in the conventional PET fiber production process lacks a corresponding unloading weighing mechanism, which controls the unloading amount through time, and the accuracy is not enough; resulting in poor weight consistency of the subsequent packaged finished products, which is not conducive to Improve the market competitiveness of enterprises;

[0011] Eighth, manual packaging in the packaging process of conventional PET fiber production is costly and laborious, and because the manual speed cannot match the production rate of the previous process, it is not conducive to increase the packaging manpower or reduce the production rate. Increase production capacity and reduce costs;
