Polypropylene yarn production process analysis!
Definition of Polypropylene yarn
Polypropylene yarn is a kind of silk-like fiber line made of polypropylene raw material, which has the characteristics of high strength, high toughness, resistance to longitudinal strength and softness. Polypropylene yarn is widely used in textile, locomotive, ship, automobile, electronics, petroleum, chemical and other industries, with broad market prospects
And the application prospect.
Second, the production process of polypropylene yarn
The production process of polypropylene yarn includes several stages such as selection of raw materials, pretreatment, processing of polypropylene fiber, stretching of polypropylene fiber, winding of polypropylene yarn and inspection of polypropylene yarn.
1. Selection of raw materials
The raw material of polypropylene yarn production is polypropylene particles. Polypropylene pellets are polymer materials manufactured from petroleum, and their selection needs to meet national standards and meet production requirements.
Step 2 Pretreat
After the polypropylene particles are stored, they need to be initially screened, cleaned and dried to facilitate the subsequent manufacturing process.
3. Processing of polypropylene fiber
In the process of processing, it is necessary to melt the polypropylene particles, filter, add stabilizer, catalyst and other treatment, and then make them into filament by spinning machine.
4. Stretch of polypropylene fiber
During the stretching process, the filament needs to be stretched to obtain better tensile and strength properties in the longitudinal direction for subsequent processing and production.
5. Winding of polypropylene yarn
The stretched polypropylene filament is wound into yarn by winding machine, and an appropriate amount of lubricant and other substances are added in the winding process to ensure that the yarn is smooth, soft and elastic.
6. Inspection of Polypropylene yarn
Polypropylene yarn after winding, the need for quality inspection, after the confirmation of the packaging factory, with good product quality and market competitiveness.
Third, the application field of polypropylene yarn
Polypropylene yarn is widely used in various fabrics, synthetic leather, rigging, paper, wire rope, cylinder fiber and other fields. Especially in the fields of wire rope making, paper strengthening, transmission belt application, protective rope manufacturing, polypropylene yarn has incomparable advantages over other materials in the market The field has a wide range of application prospects.
