Air jet spinning and product characteristic and Application
Issue date: 2008-1-22 15:38:57 visits: 272 [Chinese] industrial control network
1 air jet spinning machine and spinning principle of jet spinning is the second rotor spinning, friction spinning developed a new spinning method, it
is with the help of compressed air in the nozzle to produce spiral airflow after drafting yarn false twisting and winding of a novelty yarn method,
which is composed of two parts composition: one part is the parallel fiber yarn core, the other part is wrapped in yarn core outer wrapped fiber.
Wrapped fiber centripetal Ying Lishi will on core fiber, yarn body necessary cohesion to bear external stress.Its basic principle is the application
of the two direction opposite to the nozzle flow.Fiber by high speed after drafting, drafting zone feed to the front roller and yarn output roller
between two series nozzle.
Article a nozzle in the fiber opening, and the opening of the free ends of the fiber wrapped in yarn core fiber bundle; second nozzles on twisting
action. Leave the output roller yarn surface fiber wrapped and presenting no twist yarn core.
The yarn structure and strength by adjusting the air pressure and the change of two spray pipes.Air jet spinning technology from the nineteen sixties
USA DuPont Co developed the first single nozzle wrapped yarn spinning machine to Japan in 70 after 8 years of development, in 1981 launched the first
generation of double nozzle of air-jet spinning machine with three rollers, has been completed from test to industrial production,louboutin pas cher, after the continuous research to improve, and development the success of N0802MJS type and N0881 type MJS air jet spinning
machine, realizes the on-line monitoring, automatic joint and automatic doffing,louboutin, embodies the mechanical and electrical integration of high-tech level.
As a result of swirl nozzle gas flow speed in the 10070000 R / min 30070000 R / min, so using air jet spinning theory can reach very high
productivity.Is considered the most promising spinning technology,louboutin.
The current use of more, is more mature jet spinning system of domestic SFA5802A type; murada MJS801 type, MJS802 type, MJS881 type; Japan Dongli
AJSl01 type, AJSl02 type; German thread Sen type Plyfill000, type 2000; Japan Toyota TYS; French ARCT RS300.
The 2 international jet spinning development according to statistics, by the end of 2001, there are about 220000 head of air jet spinning device,
distributed in 36 countries and regions, the North America accounted for about 73%, Asia accounted for about I 9%, central and South America, Europe,
Australia, Africa, accounting for about 8% of.
The United States is the owner of air-jet spinning machine for most countries,louboutin pas cher, a total of about 150000, accounting for 70% of the world total.
China has 8956 heads, only accounts for the world total 4.
17%, 6.08% are american.The United States of America only ring spinning about 4000000 ingot, is China's 10% or so, but the development of new spinning
(such as air jet spinning, air spinning, the momentum has not reduced).
South in air jet spinning speed, high yield, less labor, become the United States of America textile industry development priorities.The data
presented, in recent years, the United States of America spindle number is decreasing, but the cotton crop increase sharply, its reason is reduction
in ring spinning at the same time, vigorously develop the air jet spinning and spinning.
The United States air jet spinning application features are: (1) scale of production is big, each factory has nearly 100 dimensions; (2) mainly used
for bedding, the United States 50% bedding uses jet
