High production technology requirements
Since most of the color spinning yarns are produced by mixing and mixing spinning yarns with different color fibers and different performance fiber materials, in the production process, it is necessary to ensure that each fiber blending ratio is accurate and the mixing between the raw materials is uniform to ensure the stability of the yarn quality. The requirements for good yarn, low hairiness, low number of defects, and small defects make it difficult to produce technology.
The first is the difficulty of production management. Due to the small batch size of color spinning yarns, the large variation in the blending ratio, and the large number of colors, the protective isolation in the production workshop is particularly important. The foreign fiber and crossover are often the most common complaints from customers.
Followed by color control is difficult. The consistency of color spinning yarns is a difficult point in the control of the production process. Even if the raw materials of the same batch number have a certain color difference during the dyeing process, this will bring the color difference of the controlled color spinning yarns to the spinning process. Big difficulty. In addition, the difference in color between raw materials of different batches, the influence of the degree of regain of raw materials on the color shade, and the mixing of raw materials are also the difficulties in controlling the color difference of the yarns.
Again, it is difficult to control proportional accuracy. In the fiber blending process control, due to the different mixing methods and the formation of the semi-finished products in the production process are all fluctuating patterns, there is a big difference in itself. As far as color spinning is concerned, since the fibers themselves have different colors, they are more apparent in the spinning process.
The source grasps the quality of protection
According to production experience, to ensure the stable quality of colored spinning yarn, we must start from the source: strictly control the procurement of raw materials, the control of cotton distribution, the optimization of production process routes and production management.
In the procurement of raw materials, the raw materials must first be consistent in color, especially between the same batch number and the same package, and there can be no difference in color. The second reason is that there can be no foreign fiber in the raw material (here, the foreign fiber refers to a different type of fiber or a different color of the same type of fiber).
With regard to the control of cotton blending, according to the customer's demand for the variety, it is determined that the raw materials with different batch numbers or the same lot number are used for the inspection of the quality of color, foreign fibers, and defects by the combination of instruments and sampling. In addition to the use of raw materials before entering the workshop on the machine to be packaged by the contrast color, package by package inspection, for the abnormal batch number or package single use or separate processing.
At present, color spinning yarns often have phenomena such as zebra crossings, cross bars, and hair-spreading on the cloth during post-processing. The fundamental reason is mainly due to the uneven mixing between the fibers. This phenomenon is even more pronounced when the proportion of one of the fibers is relatively small. According to experience, in order to ensure uniform mixing between the raw materials, the raw materials are generally first mixed with a cotton pad, and at the same time, 3 to 4 slivers are mixed in the drawing process. This method of blending on the one hand ensures the accuracy of the proportions of the various fibers in the sliver, on the other hand it also ensures the homogeneity of the mixing of the raw materials in the yarn body.
Process configuration should be reasonable
The colored fibers in the colored spinning yarn are dyed with loose fibers. In the dyeing process, due to factors such as dyes, auxiliaries, and high-temperature drying, the strength of the fibers is reduced, and the length of the fibers is slightly shortened. The elasticity of the fiber also has a certain loss, so the configuration of the spinning process and the configuration of each process have a great influence on the quality of the colored spinning yarn.
(1) According to the characteristics of many kinds of color spinning yarns, small batches, and frequent varieties during the production process, the combing process is mostly combined with short-flow and low-loading units. The main focus of the cleaning process is the mixing of fibers. In order to reduce the production of color aberrations and damage to the fibers, the cleaning units mainly focus on finely grasping cotton and softly opening, and strive to achieve small, fine, uniform, and full grasp. In the carding process, following the idea of ​​simplifying the complexity and reducing the need for repeated adjustment of equipment, the focus is on strengthening the combing of fibers. The purpose is to eliminate defects such as colored neps caused by dyeing, and to reduce the damage and improvement of fibers. Success rate.
(2) Carding process According to the characteristics of various fibers, the principle of “light weight, low speed, and large control of carding gauges†should be adopted in production.
(3) The parallel drawing process uses three parallel bars and the last one is an autolevelling drawing frame.
(4) Due to the poor cohesion of some color fibers and the serious electrostatic phenomenon, the twist coefficient of rovings should be controlled to a large extent, and the tension of rovings should be controlled to reduce the unexpected elongation of rovings and improve the dryness of the spun yarns and the uneven weight of the yarns.
(5) In order to improve the quality of yarns, improve strips, and reduce yarn defects, the spinning process adopts the Siro compact spinning technology and implements the “large front and rear zone roller gauges, small rear zone draft multiples, and tweezers. The principle of "mouth gap", at the same time, adopts low-speed, heavy-pressing measures. The winding process is mainly the control of the electric cleaning process, and the principle of reasonable cutting is adopted, and efforts are made to eliminate harmful defects while reducing the phenomenon of miscuting and cutting.
Protective isolation must be done
The production management of yarn spun yarns is both the focus of control and the difficulty of control. The reason why it is important is that there are raw materials and semi-finished products of various colors in the production process. If they are mixed up, they will cause the foreign fibers to mix in or cause color differences, which will cause greater losses in the subsequent processes. The difficulty lies in the fact that the isolation in the production process is the least easy to do well. If the separation is not good, the freeness of the fiber will cause the foreign fiber to be added.
The following points can be taken during the production process:
First, adopt single-unit and single-station isolation. The front spinning combing line group, the coarse single station, and the spinning single station are isolated in a fixed manner to avoid the floating of the fibers during the production process to cause the foreign fibers to mix.
Second, fix transportation routes and containers. For the different colors of raw materials, semi-finished products, flowers and other waste to take a fixed route and access, while the use of vehicles, bobbins and other containers are also fixed use and make a clear indication, the container should have a protective cover to seal well Can be transported.
Third, fixed staff look at the car. According to the variety of colors produced, fixed special personnel should look at the fixed machine to avoid mixing of foreign fibers caused by the flow of people. Fourth, fixed air supply and return air. According to the isolated area, the air conditioner adopts a separate air supply and return air, and at the same time, a separate temperature and humidity control is applied to the isolated area and the humidity is controlled to be large, and the return air of the air conditioner is filtered and used.

Hot Sale watches for SMAEL brand
From the mid-nineteenth century, someone put a chronograph watch on a belt and used it on the wrist, gradually improving, reducing the body shape, beautifying the style, and developing into a watch.
Watches can be divided into the following two types of mainstream watches on the market according to their use of oscillators: 1. Mechanical watches: clocks adjusted by mechanical oscillators. 1. Manual mechanical watch: It adopts a hand-winding movement. The mainspring of the movement is fully wound by turning the watch. When the mainspring is fully discharged, the gear is driven to run and the pointer moves. 2. Automatic mechanical watch: The self-winding movement is driven by the weight of the oscillating weight in the movement, but the swing of the arm wearing the watch will drive the oscillating weight to rotate, and at the same time drive the mainspring in the watch to wind the watch and push the time.

maintainance
When the temperature of the electronic watch is 25~28℃, the time error of one day and night is less than one second, when the temperature is below 0℃ or above 50℃, the day and night will be slow by two seconds. At the same time, when the temperature is as high as 60℃, the LCD panel will turn black, and when the temperature drops below 0℃, the LCD panel will lose its display function. Therefore, in winter, electronic watches can only be worn on the wrist and rely on the body's constant temperature to maintain it. The normal timing. In addition, high temperature and low temperature can cause battery leakage and corrode the movement. The battery of an electronic watch is generally usable for more than one year, but the lighting lamp consumes a lot of power, and the power consumption for one second of turning on is equivalent to more than one hour for timekeeping. When the battery is running out, the light will dim, or the digital display will dim or even disappear when it is turned on. When replacing the battery, if you don`t know how to repair the watch, you should send it to the repair shop for installation. Moreover, the battery specifications are not standardized, and there are many batteries of various brands, which cannot be used at will.
Electronic watches should pay attention to: Press the button too hard to avoid malfunction; the LCD panel needs to be replaced for five to seven years; the battery should be taken out in time if there is no electricity to prevent the fluid from corroding the movement. If the light is not on, the button is out of order, or there is a sudden large error in the timing, it should be repaired in time. It may be that the solder joint of the component is poorly contacted or taken off. Electronic watches, especially digital electronic watches, generally have poor waterproof performance. Although some have the words "waterproof" printed on the manual or back cover, try to avoid contact with water. The structure of an electronic watch is different from that of a mechanical watch. They are all electronic circuits and electronic components. If water enters, it will be "catastrophic" and the entire watch will be scrapped. Especially for LCD panels and integrated lines, not only are they afraid of water, they will also fail over time if they are exposed to moisture. Therefore, it is best to take off the watch when washing your face and washing. When it rains, prevent splashing rainwater. If you find that water has entered the electronic watch, or moisture has accumulated on the inner wall of the watch cover, you should immediately send it to a watch repair shop for water removal and moisture removal.
belt
Prevent contact with water and moisture to avoid discoloration and deformation of the belt.
Prevent long-term exposure to the sun to avoid fading of the belt.
Because the cortex is easy to penetrate, it prevents contact with grease or cosmetics.
The gold-plated layer on gold-plated watches is mostly 14K gold, which contains a certain amount of silver in addition to 58.5% of pure gold. After the silver reacts with some volatile industrial waste gas in the air, a black silver sulfide film will be produced on the surface, which will make the gold-plated watch lose its golden luster. Therefore, wearing gold-plated watches should avoid exposure to chemicals and exhaust gas, such as coal gas, liquefied petroleum gas, and sulfur soap, and always keep gold-plated watches dry and clean. It is best to wipe with a flannel once a week. In addition, the chloride in sweat is very corrosive to gold-plated watches. When gold-plated watches are stained with sweat, they should be wiped clean in time to prevent the sweat from eroding the watch and losing its original luster.
The yellow-plated layer of yellow-plated watches is a metal film composed of copper, zinc, and aluminum alloy. Before wearing the yellow-plated watch, wipe the case with a clean soft cloth, and evenly apply a layer of colorless nail polish, and then wear it after drying, and then apply it once every 1 to 2 months. After such a treatment, not only can the color of the yellow-plated watch be maintained without being worn, but it can also increase its appearance and brightness, and at the same time, it can prevent sweat and moisture from entering the watch in the hot summer.
quartz
â‘ Avoid strong shocks: Although the watch has anti-vibration function, you should still avoid sudden shocks. Therefore, it is best to remove the watch when doing exercises. â‘¡ Keep away from magnetic objects: Watch parts are made of metal. Although they have anti-magnetic devices, they may cause the time to be inaccurate when encountering magnetic objects. Therefore, it is best to place them next to electrical appliances such as radios and televisions. â‘¢ Do not wash quartz watches: Waterproof is generally life waterproof. It can only prevent occasional hand washing and rain splashing. You cannot wear it for bathing or swimming!
The most common condition of sending a mechanical watch for repair is nothing more than water ingress and collision. Unless a mechanical watch is marked as having a waterproof function, be sure to avoid water entering the watch case, because water will cause mechanical corrosion and be very destructive. The sea water is even more untouchable. Even if the waterproof watch is indicated, it can only have one year of waterproof protection, because the watch's waterproof ring will be worn out after a whole year of wear and tear, coupled with various unavoidable external factors such as sweat and dust, so after one year It must be replaced with a new waterproof ring, otherwise it will not have the waterproof function.
In addition to being waterproof, it is also important to prevent collisions. As far as the economic capacity permits, you might as well have two or three watches to replace in your daily life: wear a mechanical watch during static activities, and a sports watch during exercise. This will help extend the life of the watch when you use it according to local conditions. Mechanical watches are driven by mechanical gears and clockwork, and friction is unavoidable in rotation, so it is necessary to add oil and lubrication over time to reduce the wear rate of parts. Otherwise, wait until something goes wrong before sending it for repair, often the problem is already serious. It is best to go back to your mother`s house every year for mechanical watches to check for improper use or water ingress. In particular, Taiwan`s climate is hot and humid, sweat, rain, and dirty air have accumulated over the years, causing chronic erosion of machinery. The frequency and extent of damage are much higher than those in Europe, America and Japan. Therefore, "regular inspections" are very important; then every three years A thorough cleaning and maintenance are required.
The safest maintenance and repair, it is safer to hand over to the orthodox agency. The internal cleaning must be handed over to a professional master, and the external cleaning work, the owner of the mechanical watch may wish to do it himself; scrub the strap with a soft brush dipped in cleaning fluid, and finally rinse with water. Watch cases with waterproof function can also be cleaned in this way; watch cases without waterproof function must not be scrubbed. Daily cleaning of the exterior is very important, because even if the perspiration, dust, etc. are so subtle that they still accumulate, the strap will rust, rot or become brittle if it is not cleaned. Therefore, it is best for the owner to wash frequently.
