How to develop the production process of polypropylene super fine denier?
1.The formulation or selection of the production process parameters of polypropylene super fine denier fiber must be based on the characteristics of small fine denier fiber monofilament, large number of roots and large specific surface area of the filament, and reasonable selection of processing speed, each channel overfeed, tensile multiple and compressed air pressure is the key to production.
2. In the production of polypropylene super fine denier, it is appropriate to choose soft polyurethane friction disc, use slower processing speed and lower stretch times, control the appropriate winding tension, and improve the hardness and unwinding performance of the silk ingot.
3. The technology of production of polypropylene super fine denier is feasible. The market prospect of the product is broad.
Polypropylene ultra-fine filament specifications: 50D/15F -- 180D/160F FDY filament, polypropylene ultra-fine filament FDY filament, FDY ultra-fine filament.
The polypropylene super fine denier produced by our company has the following advantages:
1, the lightest fiber: the smallest density, 40% lighter than cotton, 30% lighter than polyester, gentle lubrication;
2, warmer than wool fiber: thermal conductivity is the lowest existing natural fibers and synthetic fibers, heat loss rate is low
3, good color fastness: the color fastness is unmatched by other fibers after dyeing and finishing;
Polypropylene super fine denier is mainly used in sportswear, woven fabric, seamless underwear, sports socks and so on
Polypropylene ultra-fine denier breathable fiber - water transfer and sweat, fast drying, odor is not easy to remain
Polypropylene super fine denier has soft texture, good adhesion, soft luster, commonly used in the production of silk fabric, velvety fabric fine denier sewing thread, socks and filter materials; At the same time, because this fiber has excellent antibacterial properties, it can be used in the medical field. In addition, it can also be used in higher value-added industries and biological fields. The technology of polypropylene ultra-fine denier was developed in the 1980s.
Polypropylene ultra-fine denier can be used more, clothing can be used, especially for functional clothing such as quick drying clothes can be used, children's clothing can also be used, a wide range of uses.
