Related properties of polypropylene fiber!
polypropylene fiber is a synthetic fiber, spun from isotropic polypropylene obtained by propylene polymerization, also known as polypropylene, today Xiaobian will take you to
The related properties of polypropylene fiber were analyzed.
Performance characteristics of polypropylene fiber
(1) Light weight
The density of polypropylene fiber is 0.90-0.92g/cm3, which is the lightest of all chemical fibers, 20% lighter than nylon, 30% lighter than polyester, and viscose fiber
It is 40% lighter, so it is very suitable for making wadding for winter clothing or fabrics such as ski clothing and mountaineering clothing.
(2) High strength, good elasticity, wear resistance, corrosion resistance
High strength of polypropylene (dry, wet state of the same), is the ideal material for the manufacture of fishing nets, cables; Good wear resistance and resilience, similar in strength to polyester and nylon,
The rebound rate can be comparable to nylon and wool, and is much larger than polyester and viscose fibers: polypropylene has poor dimensional stability, easy to pilling and deformation, anti-microbial, no
Moth: Chemical resistance is better than normal fiber.
(3) It has electrical insulation and heating property
The positive rate of polypropylene fiber is very high (7x10199.cm), the thermal conductivity is small, compared with other chemical fibers, the electrical insulation and heating property of polypropylene fiber is the best, but added
Working hours are prone to static electricity.
(4) Poor heat and aging resistance
The melting point of polypropylene fiber is low (165~173 ° C), and the stability of light and heat is poor, so the heat resistance and aging resistance of polypropylene fiber are poor and not resistant to heat. But can
The anti-aging properties are improved by adding anti-aging agents during spinning.
(5) Poor hygroscopicity and staining
The hygroscopic and dyeing properties of polypropylene fiber are the worst in chemical fibers, almost non-hygroscopic, and its moisture regain is less than 0.03%. Fine denier polypropylene has strong
Core suction, water vapor can be eliminated through the capillary in the fiber, made of clothing, clothing comfort is better, especially ultrafine polypropylene fiber, by
The increase in surface area can transfer sweat faster and keep the skin comfortable. Because the fiber is non-hygroscopic and the shrinkage rate is small, the polypropylene fabric is easy to wash and dry
The characteristics of.
The dyeing property of polypropylene is poor, the color is light, and the dyeing fastness is poor. Ordinary fuel can not make it dyed, colored polypropylene is mostly produced by pre-spinning coloring.
The fuel complexing agent can be mixed before melt spinning by coloring and fiber modification with the stock solution.
Second, classification of polypropylene fiber
Polypropylene fiber can be divided into long fiber, short fiber, spunbonded non-woven fabric, melt-blown non-woven fabric and so on.
Polypropylene long fiber can be divided into ordinary long fiber and fine denier long fiber (monofilm density <2.2 dtex, can be used for the production of clothing and decoration and some industrial filament
Product. Polypropylene fine long fiber good luster, soft feel, good drape, low density, suitable for knitting industry, with cotton, viscose silk, silk, ammonia
When woven into cotton cover C, silk cover C and other products, it is the ideal material for making high-end sportswear, T-shirts and so on.
Shandong Huimin Taili Chemical Fiber Products Co., Ltd. was founded in 2017, the company now has the domestic advanced fiber production line, twisting production line. Anti-aging, acid and alkali resistance, low boiling water shrinkage, high breaking strength, low elongation, environmental protection and pollution-free. Widely used in chemical fiber rope net, fire hose, sling, safety belt, concrete, mortar, engineering fiber, etc., is to replace polyester, nylon, ethylene fiber, nylon, glass fiber new ideal material.
