Why do raw cotton dyeing and its spinning processing?

In order to fully improve the added value of colored product, except add patten, high-count yarn & blended yarn and special dyeing process can also be used to achieve a unique style of colored cloth. Pure cotton blended yarn-dyed fabric: soft feel, breathable, strong water absorption. In recent years, it has been favored by the majority of consumers. Color cotton by mixing cotton, carding cotton, spinning, weaving to eliminate color difference, it is convenient production. RAW MATERIAL REQUIREMENT 1. Raw cotton requirement After the raw cotton dyeing, the color cotton should be mixed, combed, spun, and finally wovenhttps://www.yarnfabricdyemachine.comknitted, and the requiements of color difference is not strictly, so it is suitable for any variety of raw cotton. 2. Dye compound The dyestuffs and auxiliaries are used for cotton bleaching and dyeing: with fine particles and soluble in water, good diffusion and permeability.   DYEING In order to obtain better color mixing effect of cotton textiles, pay attention to two important points in raw cotton dyeing: remove natural impurities of loose fiber and spinnability of dyed cotton fiber. 1. Pretreatment Cotton fibers contain many symbionts, such as waxes, nitrogen, pectin, minerals and natural pigments, cottonseed shells, etc. The existence of these symbionts will seriously affect the wettability of cotton fiber, making it difficult to dyeing, so it must be removed first. The pre-treatment of raw cotton dyeing: boiling and bleaching and related washing. The purpose is to remove cotton impurities, fruit gum and natural pigments that hinder dyeing. After boiling and fully washing, it is necessary to check whether the concentration of alkali, residual hydrogen peroxide and whiteness meet the process requirements or not. Generally, the whiteness of the cotton fiber after pre-treatment are consistent, and the pH value is neutral. 2. Raw cotton dyeing Using direct dyes and reactive dyes, considering the color fastness and convenience of use, using reactive dyes is better, because reactive dyes with bright color, complete chromatography and a certain wet processing fastness. The process control is stable and appropriate additives, the reproducibility of dyeing is good, cylinder (batch) difference is less. In addition, the use of reactive dyes dyeing, if it is combination of color, it is best to choose a better compatibility of reactive dyes for collocation. 3.  Postprocessing Post-treatment is an important part of raw cotton dyeing, after dyeing should do fully washed and soaping treatment, in order to remove impurities and residual chemical additives on the cotton fiber. When washing, detergent with strong decontamination ability and good permeability should be used to enhance the cleaning effect of the inner layer of the fiber. After washing, in order to increase the spinnability, softening agent should be added for softening treatment to improve the lubricity of the fiber.   DEHYDRATOR AND DRYING After dehydration , the color cotton treated by softener is easy to loose, after production practice, the moisture return after drying is controlled at 6 to 8, with soft feel and good spinnability.   SPINNING TECHNOLOGY After raw cotton dyeing, the cotton fiber lost  spinnability processing of boiled and bleached, removed wax and oil, feel becomes coarse. In order to improve this situation, one the one hand, adding softener to loosen the cotton and improve its spinnability after full washing. On the other hand, reasonable cotton matching with raw cotton. There are two kinds of cotton matching between colored cotton and raw cotton: One is carried out in the cotton cleaning process, the color cotton and the raw cotton after grabbing cotton, mixing cotton, opening into rolls and  strips, finally spinning and knitted or woven fabric; Another one is processing during combining, the color sliver with the raw cotton sliver, through two strips, so that it is mixed into a strip, finally spinning and weaving or knitting. Through experiment, the former method is better, color cotton and raw cotton through mixing , carding, spinning and weaving, basically eliminate color difference.No matter which one is adopted, the mixing ratio of color cotton and raw cotton is generally controlled at about 0.5-10 percent, spinnability is better, don't  change the original production technology.   DYEING INTANCE 9.7tex red cotton using Shin Tong Yunn high pressure dyeing machine, bath ratio 1:15, internal and external cycle time ratio 5:3. 1.

Why the choice of dyeing machine crucial to the quality of dyed products?

There are numerous factors that influence the quality of dyed products, chief among them being equipment, dyes and chemicals, processes (procedures, formulations, conditions)  and operational factors. Occasionally, defects in dyeing can also arise due to chance occurrences. Therefore, when analyzing the root causes of quality issues, it's imperative to consider all aspects thoroughly to pinpoint the actual cause, allowing for resolution and prevention of recurring issues. According experience, product quality control measures can be implemented.   In this context, let's delve primarily into the impact of dyeing equipment on the quality of dyed products.   To achieve superior dyed products, not only must suitable dyes be selected based on the type of fiber and fabric, but also must appropriate textile dyeing machine be paired with customized and rational dyeing processes. Despite advancements in production technology and the continuous improvement of dyeing machinery, quality issues stemming from equipment are still not entirely avoidable. The primary concern related to yarn dyeing machine and fabric dyeing machine is its operational stability, efactors such as machine speed, drying condition, temperature ramp-up and ramp-down rate, and pressure control. When these parameters are tightly controlled, the dyeing and finishing machinery can ensure consistent color reproduction and reproducibility.   Textile dyeing machine pivotal role in achieving even dyeing. To this end, the following requirements are crucial:   1. **Strong Dyeing Process Adaptability**: dyeing machine must be capable of accommodating a wide range of process parameters like temperature, pressure, speed, and treatment time, as well as adjustment to dyestuff and chemical, ensuring compatibility with new processes and technologies. This ensures uniform dyeing and meets other quality standards.   2. **High Automation Level**: Automated detection and adjustment of key process parameters minimize human errors, enhancing precision control. This ensures the repeatability of processes and stabilizes product quality.   3. **Versatility for Multi Processing**: Given the limited resources in dyeing plant and ever-changing market demands,  fabric and yarn dyeing equipment should be versatile, allowing for cost-effective processing of various fabric and yarn types while maintaining dyeing uniformity and meeting other quality criteria.   4. **Low-Tension or Loose Running**: Tension is a significant factor affecting dyeing evenness. High or uneven tension can easily lead to quality issues. Hence, dyeing equipment should operate with minimal or uniform tension, preferably in a loose-running mode. It is related with the design of dyeing machine structure. In addition to the processes and operations defined, the color matching and dyeing levelness of products are intimately tied to the dyeing equipment chosen. The selected equipment must cater to the requirements of various dyeing processes, handle diverse product types, produce high-quality outputs, and be safe, durable, economical, high-speed, efficient, continuous, automated, low-energy consuming and environmentally friendly. In essence, the equipment must guarantee the quality of dyed product.

Advantages and disadvantages of drone spraying

Drone spraying is a new type of operation method in technological development. High work efficiency, suitable for large-scale agricultural pest control. This is tens or hundreds of times more than physical labor. It can complete tasks that are easy to manually complete, such as forest and mountain forest operations. So how effective are unmanned aerial vehicles used for medicinal purposes on rural land? Things often have two sides, namely advantages and disadvantages. Drone spraying is no exception, each with its own advantages and disadvantages. The advantage is that the spraying speed is fast. The crop protection drones used for agricultural spraying are generally multi rotor aircraft, much larger than typical small aerial photography drones, with longer endurance and much faster speed. Not to mention, compared to manual spraying, the spraying efficiency of aircraft is hundreds of times higher. In addition, crop protection drones can adopt two control methods: manual remote control and satellite guided control. Usually, large plots use satellite navigation to control spraying. For land parcels, seamless spraying can be achieved without losing crops. No matter how slow and careful manual spraying is, there will always be omissions at the beginning, which machines cannot match The spraying quality is also very high. The principle of drone spraying is to install the medicine box on the body of the drone, open the valve after the drone takes off to discharge the medicine, and then use the strong wind generated by the high-speed rotation of the drone blades to atomize and blow down the medicine. Due to the strong atomization and falling of drugs by the wind, the adhesion and diffusion rate of drugs is higher than traditional manual spraying, so the effect of spraying drugs in this way is higher than manual spraying. In fact, there are many potential safety hazards hidden in drones, and some issues have also been documented in previous reports. For example, during the process of spraying pesticides, if no pesticides are sprayed into the river, all organisms in the river will be poisoned. A clear river on the horizon is easily destroyed. If there are artificially cultivated aquatic products in the Tianbian River, it is easy to become an economic dispute if such a problem is encountered. In addition, the promotion of drone pesticide spraying in modern rural areas is insufficient, and there are many regulatory loopholes. Relevant departments need to introduce policies to guide and manage it correctly, avoid irreparable losses caused by technical errors, and ensure the safety of drone pesticide spraying. Therefore, if rural areas want to implement drone pesticide spraying, corresponding technical support must be provided first, and drone training must be provided to farmers to ensure that they use drones in the correct situations, thereby avoiding many problems. As long as they have sufficient technology, they must maintain consistency in the spraying process. In addition, due to its fast speed, the effect of uniform application is poor. The drone spray passes through instantly, making it difficult to mix evenly and thoroughly. The only way to overcome the problem of uneven and thorough beating is to increase the concentration of the liquid medicine, thereby increasing the investment cost. For example, when spraying drugs in cotton fields, UAV spray can not kill cotton bollworm in cotton buds, aphids on the back and bottom of leaves. Only by absorbing crops can endogenous pests be dealt with, and some pests may not be killed by endogenous agents but can only be dealt with through contact. The main disadvantage of manual spraying is slow speed, making it difficult to spray at high altitudes. It has the advantage of uniform application, which can evenly and thoroughly hit crops up and down. Save technical solutions. Although there are many advantages to using drones to spray pesticides, such as high efficiency and good quality, there are also certain limitations. For example, it depends on weather conditions. It cannot take off in bad weather and cannot work all day. It is only suitable for the vast northern regions, while the southern mountainous and hilly areas are not particularly suitable for large-scale operations. Generally speaking, using drones to spray pesticides on farmland is very cost-effective. Short time, uniform spraying, and affordable price. Therefore, more and more farmers are gradually choosing to use drones to spray pesticides on crops. There are also many smart young people who see the vast prospects of this industry, specializing in drone spraying, and the profits are still considerable. Drones are a manifestation of high-tech technology applied in agriculture, and are a progressive product of the combination of modern technology and traditional agriculture. From an efficiency perspective, it is indeed higher than manual spraying. From a practical perspective, it cannot be compared to manual operation. Drones can only spray on the front of crops, but cannot spray on the back of crops. When spraying pesticides, unmanned aerial vehicles also pay attention to the weather. Due to strong winds and heavy fog, it is impossible to operate, and manual operation can completely ignore this situation. Therefore, unmanned operation has its own advantages, and manual operation also has its advantages, which should be complementary. We cannot veto drones with one vote. We should view new things from a developmental perspective. Although there are drawbacks to drone operation, it is an assistant for the future development of agriculture.

How does a high-voltage power transformer work

High voltage transformer is a type of electrical equipment mainly used to convert voltage from the high voltage end to the low voltage end. It is mainly composed of iron core and winding. The iron core is made of highly magnetic conductive material to provide a strong magnetic circuit, while the winding is used to carry current and generate a magnetic field. The following is a brief introduction to the working principle, operation, and maintenance of high-voltage transformers. 1. Working principle: High voltage transformers work using the principle of electromagnetic induction. When a high-voltage power supply is connected to one side of the winding, current flows through the winding, generating a magnetic field. The magnetic field passes through the iron core and then senses along the winding on the other side. According to Faraday's law, when the magnetic flux changes on the other winding, an induced electromotive force is generated. According to the winding ratio, the induced electromotive force will change the voltage at the output terminal. 2. Running process: During operation, high-voltage transformers rely on external power sources to provide electrical energy. The voltage of the high-voltage power supply is connected to a high-voltage winding, while the low-voltage winding is connected to the equipment that uses electrical energy. When an external power source is powered on, high voltage current passes through the high voltage winding, forming a magnetic field. The magnetic field passes through the iron core and induces the voltage on the low-voltage winding. In this way, the voltage of the high-voltage power supply will be converted into low-voltage voltage and supplied to the equipment in use. 3. Maintenance: In order to maintain the normal operation of high-voltage transformers and extend their lifespan, the following points need to be noted: -Regularly inspect the windings and iron cores for damage, corrosion, or looseness. If there are any problems, they need to be repaired or replaced in a timely manner. -Check the insulation status of the winding to ensure that the insulation is intact. If insulation damage is found, it must be repaired in a timely manner. -Clean and maintain the cleanliness of the surrounding environment of the transformer to prevent dust or impurities from entering the transformer and causing malfunctions. -Regularly inspect and replace the insulation oil inside the transformer to ensure good quality of insulation oil and maintain stable insulation performance. -Monitor the temperature and humidity of the transformer to ensure they are within the normal range. If the temperature is abnormally high or the humidity is too high, timely measures should be taken to adjust or repair it. The above brief introduction to the working principle, operation, and maintenance of high-voltage transformers can help understand the basic principles and operating points of high-voltage transformers.

The onboard control system mainly includes flight control board, sensors, actuators, etc. The flight control board is the "brain" of the drone, responsible for processing information from sensors and calculating control commands. Sensors are responsible for collecting various status information of drones, such as attitude, speed, altitude, etc. The executing mechanism drives the various components of the drone to perform corresponding actions according to the instructions of the flight control board. 3. Control method of unmanned aerial vehicle There are various control methods for drones, including manual control, automatic control, and hybrid control. Manual control is the most direct control method, where operators issue commands through a remote control to control the flight of the drone. This method requires operators to have certain flying skills and experience, but can achieve high flexibility and real-time performance. Automatic control is the use of pre-set programs or algorithms to enable drones to autonomously complete flight tasks. This method does not require manual intervention and can greatly improve the stability and efficiency of flight. For example, in the field of aerial photography, drones can automatically capture images through pre-set routes, greatly reducing the burden on operators. Hybrid control is a combination of manual control and automatic control, which retains the flexibility of manual control while leveraging the stability advantage of automatic control. In practical applications, operators can flexibly choose control methods based on task requirements and environmental changes. 4. The development trend of drone control technology With the continuous development of technologies such as artificial intelligence and big data, drone control technology is also constantly advancing.
