[ Technical Textiles - Spinning PA6/66]
Spinning beam for PA66.
Equipment of the sub-jacket in addition to the jacket permits heating the pump block (polymer conduit) and pack from 3 directions. Optimum and uniform polymer temperature can be maintained. Furthermore, the sub-jacket, the pump block (polymer conduit), and all components that come in contact with the melt can be dismantled, in consideration of cleaning maintenance for PA66 production.
Annealing zone for PA6
Newly developed and specially designed monomer suction device with super steam sealing, its feature is the uniform heating to the required temperature in the annealing zone, reducing the dipping and keeping the longer wiping cycle on spinnerets surface.

Bi-component Spinning by TMT's.
spinning system.
Supplying with two separate Heat-medium evaporator system, it is possible to set different and optimum temperature for each polymer, in the spin packs over the entire line as well as over the spinneret surface. By keeping the loss of viscosity of the polymer melt to a minimum, that leads to reduction of a yarn break and a broken filament.
Newly developed and specially designed monomer suction system, its feature is the uniform heating to the required temperature in the annealing zone, reducing the dipping and keeping the longer wiping cycle on spinnerets surface. The air flow is controlled perfectly in the yarn path area. And also important to the quenching system is the spin finish application, which is controlled by individual inverter.

[ Technical Textiles - What is PET and PA.]
What is PA.
It is theoretically possible to produce many different types of PA polymers and all tend to be labeled carelessly under the heading of "Nylon". Given the multitude of variants and range of physical and chemical properties this is unwise. In this data file we will try to be specific with regard to the variant being referred to but sometimes the source information is not always clear. The largest volume sales are of the PA 6 and PA 6/6 variants. The other materials tend to be specialist polymers at specialist prices. In most cases the information refers to these materials. As a general family the PA group is rigid, translucent with good fatigue, creep and wear resistance. Chemical resistance varies with the variant but is generally good.
