The Specialties of Thread on Polypropylene (P.P.) Multi-Filament:
High Tenacity: Thread on tenacity is over 8.0 g/d, so can be used in high tenacity industrial yarn product such as Rope, Safety Belt and Sewing Threads
Low Cost: Thread on Polypropylene dope dyed multi-filament yarn is cheaper than Nylon and Polyester
Specific Gravity: P.P. multi-filament's specific gravity of 0.91 which is lower than other filaments, so it is the specific fiber floating above the water.
Under the same weight condition
· P.P. filament > nylon's lengths by 25.3%
· P.P. filament > polyester lengths by 51.6%
Color Fastness: Through our special efforts and experience in color matching, bright color is produced from dope dying process, and represents its wonderful character of colour fastness.
Attractive color: Because of smoothness it shines as Silk and Nylon
Fast Drying: The standard moisture content is 0% in P.P. so it is very quickly drying fiber compared to other fibres.
Cleanliness: P.P. yarn has low moisturizing characteristics, so it is very easy to clean
Climate Resistance: Because of its improved quality, Thread on gives high climatic resistance, which fits for chair covers, tent and other outdoor usages.
Chemical Resistance: Excellent resistance to Alkalies and Acids. In normal temperature, it also keeps good resistance to Sulphuric Acid, Hydrochloric Acid except fuming nitric acid. It is best for all kinds of filter woven.
Sanitary: By its character of high resistance to moisture and bacteria, this makes this product suitable for packing food products and essential commodities.
Low Heat Conductivity: P.P.'s heat conductivity co-efficient is low, relative heat conductivity (when atmosphere equal to 1) P.P. is 60, wool is 6.4, cotton is 17.0, thus keeps warm and by 3 times than cotton. Better than wool.
Low Static Electricity: Synthetic fibers contains less static electricity, especially it represent negative character for metal materials.
Effect of Heat: P.P.'s glass transition temperature and melting points are both higher than polyethylene, but lower than nylon and polyester. Its finishing temperature is almost below 130°C.
Handling: In various fibers, its color, handling almost like silk, this contains the character of softness and exquisiteness.
