Acrylic fiber is made up of synthetic fiber. Acrylonitrile by a maximum of 85% and minimum of 35% is its main ingredient. It is valuable to add that acrylic fiber is manufactured wool in its nature with wicker worked and parallel polymers besides each other results the production of cold clothe in summer and warm clothe in winter.
Orlon is one of the first acrylic fiber that produced by Deponet an American company in 1948. This hemo-polimer fiber was marketed by different names such as Orlon 81 filament and 41 style. In view of the drawbacks of texturing and dyeing of these fibers, the acrylic fiber had been prepared by the copolymerization of Acrylonitrile with other materials. The chemical structural reform of this fiber not only maintains the physical qualities but also added more remarkable qualities to it.
The Orlon fiber like the majority of fibers has bar shape but to increase their qualities and strengths their yarns will be produced in dumbbell style. Our production line the fibers are purchased in Tow shape within bales. Since it is a fiber-way it firstly enters the TOBE TOPS machine. In TOBE TOPS this fiber will be rolled and then broken to the shorter fibers. This machine produces two kinds of outputs. The first is the steamed and the second is steam-less. In the latter the fiber will pass between the plates and change into a shorter fiber. After eight hours of cooling they will be sent to the blender where these two types of fibers (steamed and steam-less) will be mixed together and converged into the Tops. These Tops will be sent to the GILL BOX1 in the next stage. Then Tops will be transformed into wicks in Gill 1 after eight feeding process and pulling or combing. It should be noted that the antistatic is added to this device to avoid static electricity of the resulting fibers. The wick of the Gill Box 1 is sent to the Gill Box 2 and then to the Gill Box 3 and finally the output will be created. The function of all three Gill boxes are the same but in every box transformation the weight of linear wick will be reduced. At this point the wick will be entered to the Finisher machine. After passing through stretching areas it will be changed to the semi-yarn. Twisting strengthens the semi-yarns at this stage and later they will be ready to be sent to the Ring machine by winding them around the bobbin. The produced yarns will be wrapped around the bobbin. Whereas the yarns around the bobbins are not enough and also the produced yarns in Ring have imbalanced thick and thin flat, so they will be sent to the Auto Conner machine. In this device each 25 bobbins will be transformed to a bigger package as a bobbin. Yarn will be passed through an area in which their imbalanced thick and thin will be edited and fasten again.
The produced bobbins from OTOCONER MACHIN will be shift to DUPLE MACHINE. There each two yarns will be changed to the one and just two yarns will be stayed besides each other without twisting each other. In the next stage yarns will be sent to the winding machine and twisted to increase their strengths.
All the double yarn goes to next section which is called HIGH BULKY. In this place for having massive and puff yarn they will be steamed and screwed around the netted spindle to be colored equally. The Netted spindle will be put in the tinting pots. After dyeing they will go to basil. It pulls the extra water from the yarn then sends to the drying machine.
In the next section the produced yarn turns to the netted spindle which is not good for offer. After drying they will be sent in place that all yarn turn through the plastic spindle. Finally they will be packaged and sent for market.
