Today, with the advancement of the threaded knitting machines, there is a special place among carpet manufacturers. Basically, the process of heatset and steaming is to enhance the quality of the yarn and finally the carpet. It has been proven to be that the use of yarn in a single weaving unit ranges between 7% and 10% of the increase in production efficiency, which will be very high in a financial period.
As noted above, this increase in efficiency is due to the elimination of many thread defects at the Heath Steing stage, and this is one of the reasons why carpet manufacturers are welcomed from thread wool. Heatstick is almost a must-have for high-tech knitting machines. Nowadays, tissue speed is increasing, and in particular, in high density carpet yarns, they have to withstand a lot of tufts, so that they do not disturb too much production.
The most important acrylic heatset yarns include:
1. More cotton yarn and more, thus reducing the amount of yarn and better coverage of the carpet
2. Reduce yarn yarn
3. Thermal stabilization and stabilization of the warp
4. Under the softer hand
5. Rust is less thread in knitting
6. Diagnosis of clips in woven carpets (carpet nailing)
In general, heatset machines use water vapor as a thermal interfacing of the heatset without damaging the yarn in either the two types of acrylic yarns or all of the synthetic yarns.
In a heatset machine, on average, 24 to 48 threads are threaded on the cage to the car. Basically, the process of steaming acrylic yarns is an essential process for high quality carpet weaving. Steaming produces high tear resistance, high dimensional strength, low surface peeling, as a result of yarn rolling, high color absorption, bulking of yarn, and creating a perfectly uniform surface with soft undercoat.
In addition to Creel, there is also a creel reservation that does not stop at the end of the first boot.
The threads enter the system, which passes through the Pre Feeding unit, known as the Knife. In this section, the threads extend into loops on each other and on a conveyor belt. In new models, the heatset has increased to increase the width of the conductive conveyor belts.
Typically, the production of a heatset machine ranges from 3 to 12 tons per day, depending on the type of yarn, the quality of yarn, the yarn's score. Then the threads come in from the conveyor belt to the steaming area.
The yarns come in the dryer after leaving the steam hoods, and then they are cooled down. Since acrylic has a moisture absorption capability, this step is essential. Then the clips go into the electronic control unit and then go to the torsion unit. Until now, unit bundles are used to prevent the line from being stopped.
It is important to note that in the lines of heats capable of stacking polyester yarns - polypropylene, polyamide-acrylic-wool and blend yarns for yarns and BCF, in TVP3, the length of the steam tunnel and the longer steaming time The operation of the heatset is carried out in a closed tunnel and the water temperature of up to 140 ° can rise, while in the LV machine and the need for acrylic yarns at a temperature above 100 ° C, the vapor in the atmospheric atmosphere is one and No pressure applied. Another point is that the TVP3 car can also be obtained from this freeze line. In such a way that the yarn can be threaded before steaming, it can be threaded from a freezing and cooling unit and then the yarn is threaded.
A yarn made from yarn is more attractive, more durable and easier to use for consumers.
