Murata’s Textile Machinery Division continues to be a recognized leader in Vortex and Air Jet spinning technology along with highly advanced winding, twisting and texturing systems that provide sophisticated textile engineering for the yarn manufacturing segment of the textile industry. Murata Machinery Limited celebrated the 10th anniversary of the Vortex spinning system at ITMA 2007 in Munich. The highlights of ITMA 2007 are given here for the interest of our readers.

Muratec and Cotton Incorporated have maintained a mutually beneficial relationship for more than 25 years, as both companies are committed to the idea that cotton fiber remains one of the most important textile ingredients.

Lenzing AG is the world leader when it comes to the technology and marketing of cellulose fibers and offers three fiber generations. TENCEL® is the first cellulose fiber which is based on an innovative nano technology that guarantees superior moisture management and optimum skin sensory properties. Lenzing Modal® and the classic fiber Lenzing Viscose® sets the quality standard in the textile industry as a whole. Lenzing FR®, the flame resistant specialty viscose fiber, prevents from heat in a variety of different applications. There is a perfect fit of Lenzing Fibers and Murata air jet technology: highest productivity is combined with best performance, as yarns out of Lenzing Fibers show superior properties specifically during washing.

According to Murata Machinery Limited (Textile Machinery division), Muratec's No.21C PROCESS CONER - (TYPE LINK CONER) has the highest delivery record all over the world. The tray to tray bobbin transport system technology which was first developed and introduced by Muratec offers following attributes.

v Quality: Tray to tray bobbin transportation between the spinning frame and the winder makes it possible to keep it clean and free from damaging the bobbin cops. It also eliminates the risk of mixed yarn counts.

v Flexibility: Lot change and switching yarn type can be adjusted by each ring spinning frame. According to production of spinning frame, winding units can be freely added or reduced by one unit.

v Higher efficiency: Since the ring cops are untouched, it ensures that the yarn layers are not disturbed which in turns leads to less breakages thus improving the efficiency.

v Easy maintenance: Simple and compact design which is easy to maintain, and it is possible to work on one winding unit without stopping the other units.

v Creating more space - 30% less Floor Space: Storage space of full or empty bobbin and bobbin transportation area are not required.

v Reducing manpower: The Link Coner automatically sorts ejected bobbins according to the amount of remaining yarn, and no operator intervention is required for handling or transportation.

v Utilizing less accessories: Link Coner needs less number of plastic bobbin tubes, and also does not damage it when supplied. Link Coner can reduce the peripheral accessories costs.

Murata also exhibited the Individual-Spindle Motor Driven TFO Twister No.3CA ECO. which meets the ecological demand of spinners and consumers. Electrical power consumption and rising energy cost is an important issue all over the world. The No.3CA ECO TWISTER has further developed since its debut at ITMA ASIA 2005. At ITMA 2007, higher speed operation can be realized and the effects on the environment are reduced, alongwith increase in the production efficiency.

No.3 CA ECO. TWISTER realizes drastic energy saving, compared with the conventional tangential belt system. With individual-spindle motor driven, compact servomotors directly drive each spindles. This efficient mechanical system provides a variety of advantages. Environment-friendly and energy-efficient twister can contributes to better quality and productivity at your mill. Some of the advantages are given as under:

v The smart drive technology makes it possible to reduce noise level ( 5 -10 dB reduction), and by eliminating belts from the conventional drive system, the dust by belt wear is also reduced.

v Number of twist and spindle speed can be easily set up with the help of one touch input through the Keyboard (RPM, S&Z,TPM).

v Since unevenness between spindles in speed is very low, the number of twist is even, thus the machine produces higher quality twisted yarn. .

Murata and Katayama co-developed the innovative Arrange Winder, which was recently awarded the 1st Japan the Manufacturing Grand Prix from the Prime Minister of Japan. The machine winds a g-splashed-pattern yarn, while joining yarns made of the different materials, counts, and colors with a high speed operation. It is possible to control the 1/f fluctuation, random number, and length by PC, and it is quite easy to program the multi-colored (materials, counts) packages, seemingly random mixing of yarn.

Therefore, according to Murata, by using ARRANGE WINDER, it is possible to produce the advanced sample and fabrics for sale at one process. ARRANGE WINDER helps the customer to try or produce the different lots and/or patterns easily.
