What Are The New Developments In The Development Of Colored Spinning Technology?

1. According to the coupled drafting mechanism, Jiaxing University first proposed the theory and technology of digital controlled coupled composite spinning with three base color mixed color function and three component composite yarn function. The important significance is that it can change the current single and complicated artificial colors. fibre The method of color matching can be realized by the use of three component roving (i.e. RGB three primary colors) through computer controlled coupling drafting device, alternating drafting, alternating color changing, trapezoidal color matching and mixed twisting. yarn It is no doubt that the three color conversion of TV sets is all the same. This technology is a disruptive innovation for traditional color matching technology. Colored spun yarn It is of great significance to improve the efficiency of color matching, increase the color variety and mix method of yarn, save raw materials, save energy and reduce consumption.

2, the difficulty of color spinning yarn quality control is chromatic aberration, color deviation, color start and transverse, color knot four indicators. Among them, color difference, color deviation, color start and cross are closely related to the proofing and management of color matching, and the color knot is a more difficult technical barrier. At present, the new conical card clothing developed by white shark has been processed by cone tooth to achieve the circular arc transition. The area of the tooth tip is small, and the puncture ability is strong. It is convenient for airflow to be unobstructed and fiber damage is reduced. Recommended clothing clothing: Xilin card clothing: AC2030 x 01540 (cone tooth); doffer clothing: AD4030 x 01890 (cone tooth); flat clothing: TPT52; fixed cover: 430T ~ 660T; self locking thorn roller saw blade: AT5010 x 05030V (cone tooth).

3. The new spun yarn has the advantages of high efficiency, less equipment configuration, less labor and less energy consumption per ton yarn than the ring spinning. It has obvious advantages of less appearance, light hairiness, less hairiness, dyeing rate and pilling resistance. It is worth mentioning that the new generation of CCZ-V II servo system fancy yarn device developed by Heng Heng company can meet the production method of continuous composite colored and interrupted composite colored spun yarn at present, and can produce yarn with high technical content, such as sectional color yarn, slubby yarn, Duan Caizhu yarn, elastic mixed or non mixed, composite or non composite yarn.

4, in order to ensure the color mixing ratio and chromatic aberration of the yarn, it is necessary to mix color, color and complement of the drawing frame, which involve frequent process and gear adjustment, time-consuming and energy consuming. At present, the D81S drawing frame can adjust the process quickly and accurately through touch screen buttons. However, in the process of reducing the weight of the sliver, the color uniformity of the rotor is also considered. The mixing effect of the raw materials can not be neglected because of the mixing effect of the combing roller.

5, mixing cotton evenly to prevent chromatic aberration is the key process of making lewd yarn. It is time-consuming and laborious to use artificial mixing cotton in small batch. The manual machine mixing method is more suitable for the size and the list. After weighing the required raw materials according to the set proportion, the machine can mix the cotton into the machine (for example, the FA035 and the multi storehouse mixer). The raw material ratio is weighed according to the color ratio and is fully mixed and evenly packed and ready for use. Zhejiang Hongyang holding group is through the disc mixing to transform the multi warehouse mixer to pack and use. It has solved the double clean double comb complex energy consumption and labor process.

6, semi worsted is a new spinning method developed in the field of colored spinning. Its products are between worsted and woolen fabrics, and it is suitable for the transformation and upgrading of cotton spinning equipment. It only needs pre spinning to add some woollen and woollen equipment. Cotton spinning carding machine, drawing frame, roving frame or cotton spinning frame and spinning frame can produce semi worsted products. The process of wool and wool is to control the key process of colored yarns. With the principle of "solid mixing and horizontal spreading", it is best to manually loosen or break the colored raw materials with different cylinder numbers, and then lay the layers strictly according to the technological requirements of each cylinder number raw material, so as to reduce the chromatic aberration of the long batch of raw materials. And wool machine generally need to go through two times. At present, the semi worsted yarns of multi fiber blended yarn are widely used and can provide the trend of knitting yarn. For example, weft knitting machine yarn is mainly made of chemical fiber, cotton yarn, combed wool yarn and so on. The added value of semi worsted yarns is higher than that of cotton yarn, but the technical requirements are high. It is difficult to control fiber damage, short fiber, grain, detail, and strong weak ring in the process. Spinning semi worsted yarns is a comprehensive test of the overall technology, quality control, equipment management and operation management of enterprises.

7. In recent years, the use of roving frame roving mixture has become another trend in the production of colored spun yarn. It can meet the requirements of small batch, multiple varieties, more modifications, tight delivery and large technological changes. AB yarn, siro spinning, long grain colored yarn can be realized through the intelligent modification of roving frame, which can significantly improve the production efficiency of colored spun yarn and reduce the workload of the spinning process. The formulation function of intelligent digital roving frame can achieve dozens of recipes, calls and changes, and at the same time, aiming at poor spinnability of dyed raw materials and segmented flyer speed, it can meet the best production demand.
