Who Invented The Computer Socks Machine?
Who invented the computer socks machine?
The process of making socks is mainly in the aspects of mercerizing, weaving, dyeing, baking and shaping. First, the mercerizing early socks process is not silky. In the 25th year of the Republic of China (1936), the first cotton spinning and knitting factory of China first introduced the mercerized car from abroad. After the anti-Japanese victory, the domestic hand-cranked mercerized car began to be applied, consisting of 4 rollers, commonly known as small mercerized cars. The mercerizing process is to first split the yarn, wind it up, sew it with a rope, simmer it in a light lye, then wash it, dehydrate it, then put the yarn on the mercerized car roller and tighten it. The plate is shaken by a man and a person, and the alkali is glazed. Then, the yarn is dropped, washed with water, acid is added to the acid tank, and then washed, drowned, dried, and finally finished, and the labor intensity is high. Between 1958 and 1959, the fine bleaching and dyeing factory carried out technical transformation on the small silk light car. It will shake the small plate, pull the alkali disk, add alkali to the three processes, and change from manual to electric motor drive, and the production efficiency is doubled. In addition, Fuchang Silk Factory invented the rinsing method to replace the water tank, and the acid cylinder was changed to a wooden trough, and the quality of the product was improved. At this time, the drying yarn starts to use the propulsion steam box, the light is mechanized, and the water purifier is also used for dehydration. In 1971, Knitting Bleaching and Dyeing Factory cooperated with Knitting Machinery No. 1 Factory and borrowed the experience of other industries to transform the original 4 rolls into 8 rolls, commonly known as twin studs, which doubled the efficiency. At the same time, Hongxing Factory changed the transmission part of the 8-roller mercerized car to hydraulic type, the copper bushing changed to ball bearing, improved the strength of the frame, and designed the successful pickling machine. The oven was changed from the propulsion type to the chain type. Further improve the degree of mechanization. The light trial production succeeded in the five-head skein machine, which improved the light uniformity. In the mid-to-late 1980s, the Knitting Bleaching and Dyeing Factory was made into a hydraulically driven 4-roller large-filament car with a capacity that was mechanized compared to the use of a chain-driven steam pressure cooker. In the early 1990s, wet silk and dry mercerizing processes were summarized, and cotton mercerized products were close to the level of similar foreign products. Second, the first year of the hosiery in the Republic of China, Shanghai began to have a hand-socks machine factory. Before the hosiery machine, the hosiery should be woven on the rib machine, and then the ribbed mouth should be manually transferred to the knitting machine needle to be woven. After the hosiery is woven, the sleeve is sewed by hand. The head machine is stitched into a sock. The whole process is formed in 3 steps. When the workers are operating, they must shake the machine, remember to turn the number, and the labor intensity is very high. Only 10 hours per person per day can be made into socks. In the 2nd year of the Republic of China, Jinxing Socks Factory introduced the American C-shaped electric sock machine, which is the beginning of Shanghai motor hosiery. The machine has poor performance and is semi-automatic. Like a sock machine, one person can only watch one. It was soon eliminated. In the 1920s, the sock factory introduced the electric socks machine of the American B and K models. In the later period, Shanghai has been able to make homemade. B-socks can be woven socks, hosiery socks are completely automatic, ribs still need manual operation, even the seam is still formed in 3 steps, but one can see two. K-socks function Direct weaving of the mouth, without the need of rib machine, after the stocking of the stockings still need to be seamed, is a two-step forming, one person can see six. After the appearance of the electric socks machine, the production efficiency is greatly improved, but the product is simple. The K-sock machine can only weave flat socks. Although the B-sock machine can weave the socks, it is only limited to plain and horizontal rings, and the hand-socks machine With hand-adjustable weaving, flower, cross flower, flower, mesh, jump square and many other patterns, we can also weave 60~100 men's and women's socks, long dance socks, silk and yarn rayon. Dance socks and children's socks, cotton socks, towel socks, etc. Because of the low investment and quick output of the hand-cranked socks factory, the Shanghai hand-socks machine still accounts for 40% on the eve of the founding of the new China. In the 60% electric socks machine, the K-sock machine accounts for about 90%. After the founding of New China, the hosiery process equipment has been continuously updated and updated, and the changes in the 1950s were large, mainly around the partial transformation of K, B-sock machine and hand-sock machine, to improve production efficiency and variety adaptability. In 1953, the public welfare socks factory took the lead in removing the cover of the sock machine on the squatting machine, putting on the elastic belt conveyor, and succeeding in testing the rubber band plain plain socks. After the promotion in the country. Xiangyun Socks Factory has produced cotton wool socks and children's socks on the squatting socks machine by changing the number of needles and caliber of the syringes; then Dafeng Socks Factory has improved and woven the children's socks at the bottom of the 1956, the public welfare socks factory is again A line roller is attached to the squat socks machine to weave a horizontal flower socks. In 1957, Tongxing, Kangfu and other socks factories used knives and foot pins, and the low-needle tube-shaped socks machine woven a fake rubber strip straight flower socks, breaking through the limitations of the B-sock machine can only weave the horizontal circle pattern. In the same year, Sancai Machinery Factory converted the low-needle squatting socks machine into a high-needle S-shaped socks machine, and the range of flower patterns was further expanded. In 1958, the public welfare socks factory installed the automatic woven rubber mouth device on the basis of the high-needle B-shaped socks machine, and used the knives and double-picked needle separators to simultaneously eat the line and divide the jacquard to become the automatic rubber double. Eat a double jump jacquard hosiery machine, so that the pattern changes more, once known as a kaleidoscope hosiery machine. At the same time as the K-B socks machine was innovated, the hand-socks machine was gradually reformed. The first is to install the number of revolutions on the hand-cranked rib machine to get rid of the heavy burden of the staff's operation. In 1957, the Peide Socks used a motor-driven hand-socking machine to achieve semi-automation, greatly reducing the labor intensity of workers. However, due to the limitations of the structure of the hand-socking machine, it is not suitable for the requirements of modern large-scale production. As the adaptability of the electric socks machine continues to expand, the hand-socking machine begins to shrink. After 1958, chemical fiber raw materials were used in hosiery, and each factory explored the weaving process of nylon elastic silk socks. The public welfare socks factory used two rollers to jacquard on the double-tube jacquard socks machine, weaving the bright and dark silk flowers, and contributing to the development of nylon elastic silk flower socks. In 1958, Shanghai No. 1 Socks Machinery Repair Factory (later changed to Shanghai Knitting Machinery No. 1 Factory) based on K, B-sock machine body, the machine was imitation of Japanese imported embroidery socks machine, and the trial production was successful. Monochrome hanging thread embroidery socks machine. Later, it was made into a 59-type two-color embroidery socks machine and a 59-4 double-roller embroidery socks machine, which was promoted and applied in the industry. At the same time, the Seventh Textile Machinery Factory absorbs the experience of using the three-three-hop and the vertical-type vertical flower roller in the transformation of the old machine of the public welfare socks factory, and designs and manufactures the 503 type jacquard round sock machine of the Ministry of Textile Industry. . Due to the gradual popularization of various electric jacquard socks machines, a large number of hand-socks machine products have been replaced by electric socks machine socks. By 1965, more than 90% of the hand-socks machines in Shanghai were eliminated. In the mid and late 1960s, the industry aimed to catch up with the international level and further develop new models. In 1965, Shanghai Knitting Machinery No. 1 developed the Z651 three-eating jacquard double-needle socks machine with the principle of foreign jacquard double-needle socks machine. It can weave plain, bump, rib, jacquard, jacquard, embroidered yarn, etc. Different socks are one step ahead of the single-sock socks machine. Later, Z70, Z72, Z76 and other double-needle socks machines of different performances were put into production one after another, filling the domestic gap and creating conditions for the development of new varieties. Since 1965, the public welfare socks factory has cooperated with the Shanghai Textile Science Research Institute and the Seventh Textile Machinery Factory. After three years of exploration, it has successfully developed a four-system non-dashed intarsia round sock machine with high technology. Jacquard mechanism, two-layer transmission, with 24000 jacquard comb jacquard, can be woven into large non-dashed patterns, including straight, diamond, building blocks, welt and other patterns. In 1970, the industry socks machine technology innovation team, after 121 tests, created a fully automatic one-step socks machine, from the sock, socks to the seam head one step. However, these two innovations, because the manufacturing technology is too complicated, the required knitting needles are not matched, so that they are not officially put into use. In 1978, Shanghai Knitting Machinery No. 1 Factory adopted two looping systems, multi-head thread, two-color embroidery, jacquard mechanism with a jacquard roller, and the 59-4A socks machine was changed into a 791 two-color embroidery socks machine. The range of types is wider, and it is applicable to various raw materials such as nylon yarn, nylon stretch yarn, cotton yarn, wool yarn, and rayon. In the same year, Tongyi Socks Factory reformed the 15 major parts of the Z503 sock machine, and successfully developed the 793 three-system plus horizontal jacquard sock machine, which increased the speed by 20% and became a special equipment for woven nylon elastic stockings. In 1982, Shanghai No. 5 Weaving Socks converted the 79-3 sock machine into a needle-type jacquard towel machine. Later, the Red Flag and Happiness Socks Factory used the 51-type old machine to convert into a 2?? inch three-system jacquard sock machine and a single-chip indirect selection jacquard sock machine, enriching the variety of towel socks. During this period, the SGE5002 series towel socks machine developed by Shanghai Knitting Machinery No. 1 and the SGE5001 high-machine No. Jacquard socks machine were put into production. The SGE5001 socks machine can weave 360~400 needle high-grade socks, compiled into a set. The circle jacquard, the mesh jacquard, the circle mesh and the jacquard and other patterns have reached the world advanced level. In the late 1980s, the industry introduced a number of 400~420-pin ultra-fine pitch new socks machines from Italy, Czech Republic, Japan and other countries, which are specially used to produce high-elastic short, medium and long-length non-socks and pantyhose. Fashionable women's socks. Third, the dyed socks have two processes: dyeing and weaving first and then weaving and dyeing. Plain yarn socks and nylon stockings are first woven and dyed; color socks and nylon elastic stockings are generally dyed and woven in the 20s. In the early days, in the era of hand-socking machines, dyeing equipment was mainly stoves, dyeing tanks and stir bars, all of which were operated by humans, with environmental pollution and high labor intensity. In the 15 years of the Republic of China, steam dyeing socks appeared, heated by steam, and the first dyeing tank could dye 20 to 30 dozens each time. Since the socks are still mixed with the stir bar when dyeing the socks, quality problems such as holes and uneven coloring often occur. At the beginning of the founding of New China, most of the socks factory's dyeing equipment was still one cylinder and two rods, and the dyes were mostly direct and salt-based. Later, dyes such as indanthrene and nafto, which are not faded, were used, but the process operation was based on experience, and each set was made, and the dyeing rate was high. By 1954, the hosiery industry, with the help of the chemical department and Zhongbai Company, had made a unified material and operation regulation after investigation and summary. In 1956, the first motor socks factory created a wooden dyeing tank, the capacity is three times larger than the original number one dyeing cylinder. The crank plate of the cranking device is driven by the electric motor. The speed is adjusted by the transmission, and the efficiency is increased by 3 times than the manual operation. Stir the stick. In the late 1950s, nylon stretch stockings and nylon stockings were successfully trial-produced. In order to expand production, Shanghai Knitting Machinery No. 1 Factory successfully produced a side-pitch dyeing machine with a dyeing capacity of 20 kg. The elliptical dyeing tank and the runner are made of stainless steel. The two-speed motor is used to drive the dyeing paddle through the turbine reducer. The steam is directly heated, and the dyeing liquid is unidirectionally turned behind the machine, so as not to directly impact the body. Uniform coloring, easy to operate, suitable for dyeing all kinds of socks and stockings. Later, the reciprocating rotary bottom paddle and top paddle dyeing machine were successively made to solve the dyeing of medium and long-length socks. In 1963, the first motor socks factory successfully produced a successful roller-type dyeing machine, and the dyeing capacity was increased to 30-40 kg. The machine adopts sealed dyeing tank, and the inner drum is installed in the machine. The time, temperature and the reverse rotation of the roller are automatically controlled by the electrical instrument. The pretreatment and dyeing of the socks are carried out in the dyeing tank. In the mid-to-late 60s, in view of the use of the first weaving and dyeing process, the nylon stretch stockings affected the hand feeling, elasticity and flatness, and began to use the dyeing and weaving process. At the same time, with the substantial increase in production, the industry organization has collaborated to tackle the problem. It has successfully developed high-temperature and high-pressure overflow dyeing with a capacity of 10~20 kg. In 1975, the first high-temperature and high-pressure dyeing machine with a capacity of 50 kg in the industry was in Shanghai. The knitting bleaching and dyeing factory was successfully tested on computer control. At the end of 1976, five dyeing machines were connected, and the group control was successful, forming an automated small-scale bleaching and dyeing system. After trial and improvement, it was officially put into production on April 23, 1978. The yield and safety factor have been greatly improved, and the mixed authenticity rate of dyeing has increased from 84% to 95%. The bleaching and dyeing system can be divided into single-cylinder dyeing or multi-cylinder combination, which is suitable for small batch and multi-species dyeing. Fourth, baking, shaping cotton yarn socks are mainly blanched. In the early days, the oven was made of bricks, with socks hanging on the socks, coal burning underneath, closed box baking, low production efficiency, and the socks were easy to be baked or yellowed. In the early 1930s, steam was used instead, and the sock was cast with raw aluminum. It was a three-dimensional type. The middle hollow was connected to the steam tube. After the stockings were put on the sock board, it was dried with steam heat. It was safer than the oven, and the quality of the product was also improve. After the socks are baked, they are pressed by a press to make them smooth. In the late 1950s, with the successful trial production of nylon stretch stockings and nylon stockings, the shaping process began. Initially, using the boiled pot that was abandoned by the pharmaceutical factory, the soil method was launched, the steam tube was installed, the string of socks was hoisted into the pot, and the steam was turned on for shaping. At the beginning of 1960, the public welfare socks factory established a stereotyped pot. Except for the stockings, the process operation was controlled by electric appliances. Each set can be set to 100~120 pairs, which not only improves the output but also reduces the labor intensity. In the same year, the public welfare socks factory succeeded in the trial production of a cylindrical horizontal setting machine. The machine was equipped with two layers of rails. The sock board was put into the pot and was run by the stocking car on the track. Each set of nylon elastic stockings 150~200 pairs or nylon stockings 200~300 pairs. These two types of sizing equipment are commonly used in the industry. In 1978, the second factory of Socks further improved the design. The lifting and lowering of the pot body replaced the original screw with air pump pressure. The sealing ring of the shaped pot was changed to an inflatable seal to solve the steam leakage, and the jet pressure was applied to increase the steam pressure. The process is automatically controlled by electronics, except that the stockings are still manually operated. After being identified, it was mass-produced by Shanghai Knitting Machinery No. 1 Factory and named MZ82 vertical setting machine. At the end of the 1970s, the Weaving Socks Nine Factory and Tongyi, Yan'an and other sock factories successively tried to produce fine-pitch high-elastic nylon stockings (commonly known as non-socks), and introduced them from Italy, Czech Republic, Japan and other countries from 1983 to 1986. The batch ultra-fine needle knitting machine and three rotary setting machines are automatically controlled by the computer according to the pre-entered process. The production efficiency is 23 times higher than other setting machines and the quality is good.
