This article mainly introduces the spinning quality in detail and explains the spinning concept. Proposing ways and measures to improve the quality of spinning and comprehensively doing all kinds of spinning work can continuously promote the development of my country’s spinning industry.
01 The connotation of spinning quality control
The survival and development of a company in the market lies in the quality of its products. If the quality of the spinning products of a spinning company is not up to par, there will be no good sales. , it will be impossible to maintain the operation of the enterprise. Therefore, at present, my country’s spinning enterprises must pay attention to both aspects. First, they must ensure the stable quality of spinning products. Second, they must strengthen the improvement of spinning quality. They must continuously improve on the basis of existing quality and constantly improve the quality of spinning products. The improvement of spinning quality is closely related to spinning technology and technology. It is also necessary to strengthen spinning production management, have a clear production management system, and refine production links. Spinning enterprises must pay attention to the introduction of new spinning equipment, strengthen innovation in spinning technology, develop two-way spinning technology and management, and always adhere to the principle of quality first.
02 Main contents of spinning quality control
2.1 Strength
Strength control must be strengthened. The main raw material for spinning is cotton yarn. If the cotton yarn strength reaches 5%, it will reduce the working efficiency of the roving frame, which will seriously increase the production cost. .
2.2 Hairiness
In spinning production, it is necessary to try to Choose some short hairiness, or simply process long hairiness. If the hairiness is too long, the yarn will be easily tangled and broken, which will increase the cost of spinning production and affect the quality of spinning products. Quality and aesthetics.
2.3 Yarn defects
During spinning production, it is necessary to Strengthen the inspection of yarn defects. If there are yarn defects in spinning products, this will affect the inspection of product quality.
2.4 Neps
There are very few neps and impurities in the gray cloth. There should be no “white stars” due to poor color absorption on the cloth after dyeing.
03 Spinning quality control concept
3.1 Drafting link
Reasonably coordinate the relationship between the various spinning production processes. In the spinning production process, the drafting link is very important, but if you want to do a good job in drafting, you must strengthen the control of raw materials. For carding, it is necessary to effectively control the relationship between carding degree and carding intensity, to be able to balance the use of short staple fibers with each other, to reasonably coordinate the relationship between the various production links of spinning, and to analyze factors that may affect the quality of spinning. After comprehensive consideration, we should try to avoid errors in the early process, which will lead to the inability to carry out subsequent work and directly lead to the emergence of defective spinning products. For example, if the long and short velvet are not properly classified during the early processing of spinning, it may lead to the inability to carry out the spun yarn production process, and too many strands will affect the surface quality of the spun yarn, and many small bumps will appear, resulting in The emergence of spinning semi-finished products directly increases the cost of spinning production.
3.2 Five factors affecting spinning quality
3.2. 1 Raw materials
Before spinning production, the spinning raw materials must be carefully screened, the proportion of cotton and cotton blending must be coordinated, and the fibers must be fully mixed. Together, it can meet the needs of spinning production.
3.2.2 Technology
In the spinning process, different Depending on the spinning production process, the quality of the produced spinning will also be different. It is necessary to strengthen the design of spinning production parameters, pay attention to the innovation of spinning production technology, strengthen process testing, and find the best spinning yarn production technology and improve the quality of spinning production.
3.2.3 Equipment
Spinning enterprises want to produce spinning Yarn products are definitely inseparable from spinning equipment. Especially under the modern industrial situation, manufacturing enterprises must strengthen the introduction of spinning equipment, maintain and maintain various accessories, and regularly inspect spinning equipment to find problems. It must be dealt with promptly.
3.2.4 Production Management
Want to ensure spinning products To improve the quality of spinning, we must strengthen strict management of spinning production, ensure the cleanliness of the spinning workshop, improve the operating level of workers, and continuously improve spinning efficiency while ensuring quality.
3.2.5 Production temperature and humidity
The quality of spinning products The quality is also closely related to the production temperature and humidity. During the production process, the production temperature and humidity must be controlled, which will directly affect the moisture regain of semi-finished products, bobbins and cones. Appropriate temperature and humidity can effectively improve the strength of spinning, reduce hairiness, and reduce the occurrence of yarn defects, so it is very critical in the spinning production process.
3.3 Reduce “cumulative error”
The spinning production process is very It is complex and involves many processes, so various errors may occur. If these errors are superimposed, they can have a great impact on the quality of spinning products. Therefore, spinning enterprises must strengthen the reduction of “accumulated errors” and introduce advanced management technologies to avoid the emergence of spinning production errors.
04 Ways and measures to control spinning quality
4.1 Reasonable Equipped with blowroom, carding and combing processes
���The impact of low lint content on the quality of spinning products Since the shorter fibers cannot be effectively controlled in the drafting floating zone, it is easy to have large displacement deviations, so this will have an impact on the quality of spinning , especially the yarn deterioration is more serious. Therefore, spinning enterprises must reasonably configure the blowroom, carding, and combing processes, and carry out appropriate attacks on blowroom cotton, so as to reduce fiber damage; at the same time, they must adhere to the principle of “moderate carding transfer, moderate combing, and For carding, the card clothing and process must be reasonably selected, the short staple rate of the combed sliver must be strictly controlled, and the spinning drafting technology in the production process must be optimized to improve the quality of cotton yarn.
4.2 Preferred rubber rollers and aprons
Spinning enterprises want Improving spinning quality can also enhance the optimal selection of rubber rollers and aprons. In the spinning production process, rubber rollers with high elasticity and low hardness are very suitable for heavy pressure and can effectively improve the spinning production results. Moreover, it is also necessary to strengthen the comprehensive consideration of holding force, drafting force, and control force, to simultaneously adjust the relationship between each force, and to effectively distribute and coordinate. At the same time, it is also necessary to ensure that the rubber rollers and aprons can run at a constant speed, try not to cause cracks, and make greater use of the high yield resistance of the aprons.
4.3 Improve evenness and reduce yarn defects
Cotton yarn evenness Uniformity generally refers to the degree of weight unevenness of cotton yarn that meets the specified linear density requirements. Yarn defects include regular yarn defects and sporadic yarn defects. Among them, yarn defects with long details and long slugs are more harmful to the quality of fabrics, while yarn defects with short details and short slugs are more harmful to the quality of knitted jersey and high-density woven fabrics. Generally, quality improvement measures focus on the improvement of evenness CV value and frequent yarn defects, and there is no condition to inspect long details and long thick yarn defects. Such yarn defects should be paid close attention to during the production process and their occurrence is strictly prohibited.
Conclusion
At present, my country’s spinning industry has developed rapidly. However, there are still many problems with spinning quality. Therefore, in the actual production process, it is necessary to strengthen the innovation of production technology, introduce advanced spinning equipment, strengthen spinning production management, restrict employees from the system, and improve the overall operating level of employees. </p
