As a rising star of synthetic fibers developed rapidly. Since the 1980s, the production of polypropylene in the world has been growing at an average annual rate of 9% or more, much higher than the growth rate of 7.3% polyester and 4.6% synthetic fiber in the same period. Affected by the world financial crisis, the synthetic fiber growth rate slowed down significantly. However, the average annual growth rate of polypropylene output remained at 5.5%. The demand of polypropylene fiber basically maintained this growth trend.Polypropylene staple fiber is mainly used for: sanitary materials with non......
Production of polypropylene staple fiber Polypropylene chip as raw material, with air delivery to the screw extrusion melt spinning, and then drafting, curling, drying stereotypes, cut off, packaged to obtain polypropylene staple fiber.Polypropylene staple fiber safety points:1 observe the spinneret surface, be sure to sideways, not vertical viewing, handling board, should wear gloves to prevent scalding.2. When loading biphenyl to wear protective masks, it is prohibited to approach the fire.3 drafting process, if there is a small amount of wrapped wire can not stop and quickly pick up. When a......
Most of the production process of polypropylene staple fiber using porous, low-speed, continuous process, that is, short-spinning process. Polypropylene staple fiber and cotton blend can be made of C cloth, sheets, gloves, trousers; and viscose blend can do blankets.Company's main products of polypropylene staple fiber: Specifications 0.3-110dt, length 5-150mm, with an annual output of 30,000 tons, the color is complete. Polypropylene staple fiber is mainly used for: sanitary materials with non-woven fabrics (such as women's sanitary napkins, baby diapers, medical masks, cloaks, etc.),......
Polypropylene Staple Fiber is mainly a material to improve the durability of concrete, if the fatigue resistance as a durability index of pavement concrete, the above understanding is certainly correct. In addition, the polypropylene fiber to improve the performance of concrete, including: by reducing the bleeding of concrete, so that the surface quality of the concrete can be improved, so that the wear resistance of concrete can be improved, and the blocking effect can significantly improve the concrete The anti-leakage performance. Polypropylene fibers also have no adverse effect on other co......
Polypropylene staple fiber geotextile has excellent water permeability, filtration, durability, can be widely used in railway, highway, sports hall, dyke, hydraulic construction, tunnel, coastal beach, reclamation, environmental protection and other projects. There are mainly staple acupuncture non-woven polypropylene geotextiles and split silk woven polypropylene geotextiles.Polypropylene staple fiber geotextile function:The use of polypropylene geotextile good permeability and water permeability, so that water flow through, so as to effectively retain soil erosion.Will effectively focus on t......
The concept of staple fibers may not be so widely known as a filament today Xiaobian introduce staple fiber staple fiber family of large family, polyester staple fiber and natural fiber strength, more durable, therefore, her application far more than Natural fiber to a wide range.Polyester fiber sub-filament and short fiber two types. The so-called polyester filament, a length of more than 1000 meters of silk, filament winding into a group. polyester staple fiber is a few centimeters to ten centimeters of staple fiber.Polyester fiber features and uses:Strength: Polyester fiber strength nearly ......
In recent years, the term bicomponent fiber frequently appears in the field of view of the textile industry, like a rising star. Among them, the development trend of Two Bi-component Fiber the most optimistic, the specific reasons are as follows.Bicomponent fibers used in the diversification trend of raw materials. Under normal circumstances, the component polymer to meet and meet the requirements of the two-component or multi-component forming process and product characteristics, namely, on the one hand to consider the polymer melt temperature and viscosity characteristics, in addition to the......
Polyester fiber as one of the five major synthetic fibers, a wide range of applications, today we come to find out what is the difference between polyester filament and polyester staple fiber.Polyester fiber sub-filament and short fiber in two forms. The so-called polyester filament, a length of more than 1000 meters of silk, filament winding into a group. polyester staple fiber is a few centimeters to ten centimeters of staple fiber.Polyester fiber features and uses:Strength: Polyester fiber strength nearly 1 times higher than cotton, wool 3 times higher, so strong and durable polyester fabri......
Polyester staple fiber as one of the five major synthetic fibers, there are many taxonomies, the market is still the most commonly used large chemical fiber, chemical fiber and small chemical fiber.Large Chemical Fiber: PET staple spinning or melt spinning Polyester staple fiber. Good color, lot number, strong and stable, less defects, spinnability.In the chemical fiber: with other PET slices or with PET back spun. The quality of the price ranged from large to small (some of the major textile mills are used to enhance their competitiveness with large chemical blends).Small chemical fiber: PET ......
