Polypropylene fine denier wire process flow!
The process flow of Polypropylene fine denier wire mainly includes the following steps :
Raw material preparation : polypropylene is selected as the raw material, and appropriate additives are added according to needs, such as antioxidants, antibacterial agents, fluorescent whitening agents, etc., to improve the oxidation resistance, antibacterial property, color and other properties of polypropylene fine denier.
Melt spinning : Polypropylene is transported to the spinning box after melting, and fine denier is formed through the spinneret hole. This process needs to be carried out under high temperature and pressure conditions to ensure the fluidity and stability of the polypropylene melt, while preventing melt breakage and the blockage of the spinneret.
drawing and orientation : by controlling the drawing multiple and temperature, the molecular orientation and crystallinity of polypropylene fine denier can be improved during the drawing process, so as to improve the mechanical properties of Polypropylene fine denier wire.
Network machining : In the network machine, by adjusting the processing speed and drawing times to reduce the hair and broken ends. Proper processing speed and drawing ratio are essential to ensure the stability of process operation and product quality.
Overfeeding control : In the process of stretching false twist deformation and network, the overfeeding and winding overfeeding of the roller and the lower roller in the elastic feeder can be adjusted to control the tension of the filament, so as to ensure the opening and network effect of the filament.
Network pressure selection : Select the appropriate network pressure to ensure the quality of polypropylene filament and the uniformity of the network.
Through the above steps, you can produce Polypropylene fine denier wire with excellent performance, the fabric woven into this fiber has good sweat permeability, can keep the skin dry when wearing, improve the comfort and hygiene of the fabric, very suitable for making mountaineering, hiking and other outdoor activities of sportswear.
