Introduction Of Air Texturing Spinning Technology In Textile And Garment Industry
< p > < /p >.
Less than P > 20 years ago, there were only 3 manufacturers of air texturing machines, namely, "a href=" http://www.91se91.com/news/index_p.asp "," Germany "/a Eltex company and Barmag (Barmag) company, and American Enterprise company.
The models they offer are: AT, HS and ABS of Eltex company, FK-6T80 type of Barmag (Barmag) company, and EMAD-17 type of Enterprise company.
Today, we have more choices, such as Japan AiKi and Murata (Murata), Italy Giudici and RPR, France ICBT, and Germany Erdmann.
In the late 1980s, a series of Air Texturing products entered the market.
It includes Enterprise company's Sidewinder type, 335-|| type of Murata company, TG20 type of Giudici company, 3SDA\2 and 3SDA\4 of RPR company, AM4 type of Barmag company, type of 3SDA\4 company, and type of Lida Company.
Most of the air deformable machines in this period are small unit units, which can form a large machine.
At that time, the air texturing machine had been able to process high feed rate products at high speed, equipped with hot rollers and hot plates, heat treatment of textured yarns, and began using electronic sensors to detect broken ends.
< /p >
In recent years, the global demand for "a href=" http://www.91se91.com/ "target=" _blank "textile" /a "and industrial yarn has been increasing, and the profit margins are very large. Therefore, Barmag has made new innovations. In 2004, CATY, an air deformation machine for producing special yarns, was introduced. It can not only produce" a "href=" P "," yarn "and" yarn ", but also process air textured yarns for furniture, interior decoration and automotive equipment, as well as industrial air textured yarns, composite yarns, soft yarns, high bulky yarns and low bulky yarns.
< /p >
< p > SSM group also launched its latest high-performance air texturing machine DP2-T and RM3-T, processing speed reached 1000m\min.
DP2-T is suitable for processing medium and fine yarns. The highest machinability is 900dtex. The products can be used for knitted fabrics, seamless products and fancy twists, as well as elastic fiber composite yarns.
RM3-T is suitable for producing coarse denier and industrial yarn. The highest variable fineness is 3200dtex. Its products are mainly used for automotive interior, furniture, sewing thread and coating materials.
< /p >
< p > RM3-T is the world's first equipment capable of running air deformation and air covering two different processing technologies. It is suitable for the processing of medium and fine size yarns. The highest processing 400dtex is 400dtex, which can produce air textured yarn and elastic wrapped yarn. The switching between the two processes can be completed only by changing the air nozzle, so the operation is convenient and fast.
< /p >
< p > air deformation technology and its progress < /p >
At present, air textured yarn has been applied to clothing (suit, underwear, dress skiing shirt, sportswear, etc.), interior decoration (hanging fabric, wall cloth, tablecloth, etc.) automotive interior trim (seat cover material, car body inner layer, vehicle bushing, etc.), sewing thread, glass fiber products (fire carpet, curtain, shutter, electronic printed circuit board, etc.), tent fabric, sound buffer and other industrial uses (coating and laminated fabric, etc.), and so on.
In addition, the development of microfilaments for functional rainwear sportswear and casual wear also provides greater market space for Air Texturing Technology.
It also has the unique handle and appearance of the fabric when it has the functions of wind protection, rain prevention and ventilation.
Air textured yarns are mainly used for weft yarns to improve their feel and appearance.
According to the latest reports, underwear and clothing made of spandex during deformation are more comfortable and comfortable.
< /p >
< p > development of air textured yarn Market < /p >
< p > air deformation technology entered the textile industry in the early 1950s. The deformation rate of the early nozzle is very slow, and the consumption of 50m/min is above 20m/h.
Therefore, the air deformation technology used for processing coarse fineness of nylon, glass fiber and polypropylene filament products was mainly used as carpet or indoor.
Decorative cloth, car seat cushion, etc.
Moreover, due to the low evenness of the yarn, the shrinkage rate of boiling water is large, the size is unstable, and the post-processing is difficult. There is hardly any chance to be used in the clothing field with high quality requirements such as socks, underwear and coats.
Therefore, after more than 20 years after the advent of air deformation technology, its development and research work has been progressing slowly, with.1975 installed only 10 thousand and 500 spindles.
With the expiration of some patents due to expiry of validity period, and with the development of Eastern European and Japanese markets, air deformation technology has entered other countries and regions since the middle of 70s. At the same time, because of the continuous improvement of the core of air deformation technology, the speed of deformation has been greatly raised. The performance of air-laid yarns has also been improved, and air deformation technology has entered a good development period.
The Far East market grew by 40% in 1982.
From 1982 to 1986, air deformation technology also increased rapidly in the European market.
In the mid 80s, the American market had a frenzied pursuit of sportswear and casual wear. This fashion trend has now swept the world.
Therefore, functional clothing and yarns are favored by the market. Air deformable technology also benefits greatly.
In 1989 and 1990, far east textile countries and regions, especially Japan, Korea and Taiwan Province, invested heavily in air deformation technology.
In the past two years, the installed spindles in the Far East have almost increased by 1 times.
< /p >
< p > {page_break} < /p >
< p > increased from 38 thousand and 800 to 75 thousand and 800.
Soon, due to excess production capacity, the market for air deformable technology almost collapsed.
Over the next few years, the growth of the market continued to slow down and did not rise again until 1996.
In 1998, due to the collapse of the price of the false twist textured yarn, it was predicted that the installed spindle position of the air texturing machine would reach 100 thousand spindles, and the same is true.
Although air textured yarns occupy a small share of the whole textured yarn market.
In the middle of the 2O century, the output of 7O was only about 2% of the total output of textured yarn.
But the air variant yarn has been on the whole with the whole textured yarn market since its appearance.
< /p >
< p > development keeps abreast of one another.
In 2003, the world's installed spindle position was close to 150 thousand spindles, the third largest deformation processing technology. Its market share has risen to 7%.
< /p >
< p > < strong > Testing Technology of air textured yarn < /strong > < /p >
The development of testing technology for air textured yarn is also very fast. The most representative thing is to evaluate the appearance quality and porosity of air textured yarns by using the electronic inspection board (EIB) of American Lawson Hemphill company (P).
In 1999,.Ghosh and so forth put forward a new test index of air textured yarns bulking degree, that is, EIB bulking degree. It is a comprehensive index considering the number of yarns and the total number of yarns. The results show that there is a good correlation between the EIB bulking degree and the traditional bulk density method.
In 2003, Vanneste and so on used EIB41 day} textile guide ChinaTextileLeader.2006No.1 to evaluate the surface characteristics of air textured yarns.
In 2004, Wang nun waited to test the line density and diameter of air textured yarns by EIB. The bulk density of yarn was used to characterize the bulkiness of air textured yarns.
EIB continuously scan the samples at the speed of 100m/min. It can show the yarn core diameter and average diameter, standard deviation and coefficient of variation, hairiness and distribution of different heights, as well as gross hairiness. It is not only easy to operate, fast and accurate, but also has no requirement for samples and testing environment. It is a very promising testing method that can realize on-line detection and control of the appearance quality of air-cooled yarns.
< /p >
< p > < strong > progress in quality control technology of air textured yarn < /strong > < /p >
< p > there is no on-line quality control device for imported or domestic air deformation equipment.
The Eltex air texturing machine introduced in the 80s of last century is only equipped with filament broken ends, yarn breakage self stop device and full tube self stopping device. The quality of the yarn needs to be tested after being tested in the laboratory. Therefore, the production process is mainly determined by experience.
Until the mid 90s,.Barco launched a quality monitoring system for air deformation technology, that is, BarcoProfile.
At present, more than 10 thousand air texturing machines are equipped with this device to realize the online quality of the textured yarn and the production process.
< /p >
Control at < p >.
The device has a standard measuring accuracy of 0.011111. and a maximum measuring accuracy of 0.005mm, so that the smallest diameter of the textured yarns can be detected.
The 3 important quality on-line analysis of the BarcoProfile device are: 1) the diameter CV value, that is, the diameter variation coefficient, which reflects the uneven deformation effect or the bulking degree of the textured yarns.
According to the CV value, it can be found whether the nozzle is damaged or dirty. Is there any mistake in adjusting the nozzle? Is there any problem with water supply and whether the spinning auxiliaries are completely removed, and whether there is a problem with air pressure?
Because the variation of the air pressure inside the nozzle is too large or too small, it will affect the deformation effect: 2) the yarn count. The device directly provides the number corresponding to the diameter of the textured yarns.
If a set of feeding yarn is broken or wound on the guide leno, then the yarn becomes finer. If the draft area is not drawn, more yarn is added or the yarn specification is wrong, then the yarn becomes thicker and the winning diameter increases. 3) the defects of the coarse and fine sections usually occur when the deformation nozzle is smear.
This defect will seriously affect the smooth progress of the weaving process. Therefore, if problems are found, they should be solved in time.
Besides the quality control, the.BarcoProfile device also has the actual production monitoring capability, including accurate length measurement to ensure uniform packing efficiency calculation and production measurement.
< /p >
< p > 2003, Sweden Retech company introduced the online measuring device for yarn tension of air deformation processing -- the ATG Light system.
Because the yarn tension reflects the process well in time, for example, when the nozzle is stained, the yarn tension will gradually decrease.
The device is simple in design and consists of a yarn with LED.
The tension sensor is composed of an input end.

The actual yarn tension of "P > < strong > > < /strong > < /p >
< p > it is specially designed for those occasions where there are no expensive and complex software, PC or control rooms.
JOYTM is an online yarn quality control system developed by SSM group. It is mainly composed of a yarn tension sensor, a single yarn electronic detection sensor, a monitoring device with error display, a temperature monitor, a winding density adjustment device and a production data controller.
The system can detect all the potential factors that cause defects in the process of air deformation, so as to avoid any defective yarn in post processing, for example, the nozzle is stained, water supply is not uniform or water shortage, air pressure is not stable, temperature fluctuation, and feeding yarn is missing.
The device not only effectively controlled < a href= "http://www.91se91.com/news/index_s.asp > yarn > /a > quality and production, but also simplified production and process management and reduced the cost.
