Polypropylene staple fiber is a single fiber that can improve crack resistance, impermeability, anti-wearing ability, anti-freezing ability, anti-explosion ability, and workability of concrete. Short polypropylene fibers are evenly distributed in mortar and concrete, which keeps the structure's integrity well and prevents it from dispersing into many fragments when damaged by impact. This prevents the corrosion of steel bars in the structure, extending the service life of the project and reducing maintenance costs.
Polypropylene staple fiber is used in anti-cracking putty powder, thermal insulation mortar, concrete, construction engineering levels, walls, floors, pools, basements, and access bridge engineering. It has anti-cracking, wear resistance, toughness, and impact resistance, explosion-proof benefits, as well as resistance to tearing, and the improvement of bonding in old and new interfaces.
Polypropylene staple fiber has superior moisture permeability and quick-drying properties, good combability, and spinning performance, and can produce soft and tough fabrics. The fabric is light in weight, warm, delicate in hand, and comfortable. It is also acid and alkali resistant and has quick dissolveability, good filling, and insulation.
Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by polymerizing propylene as a raw material, with the trade name polypropylene fiber in my country.
Polypropylene fibers can be divided into long fibers, short fibers, spunbonded non-woven fabrics, melt-blown non-woven fabrics, etc. Polypropylene long fibers can be divided into ordinary long fibers and fine denier long fibers (monofilament size ≤2.2 dtex, which can be used to produce clothing, decoration, and some industrial filament products). Polypropylene fine denier long fibers have good luster, a soft feel, good drape, low density, and are suitable for the knitting industry. When interwoven with cotton, viscose silk, true silk, spandex, etc., into cotton cover acrylic, silk cover acrylic, and other products, it is an ideal material for high-end sportswear, T-shirts, etc.
Most production processes of polypropylene staple fiber adopt a porous, low-speed, continuous process, specifically a short spinning process. Polypropylene staple fiber blended with cotton can be made into polypropylene cotton muslin and bed sheets. Polypropylene blended with viscose can be used for blankets, while pure spinning and blended yarns can be used for polypropylene blankets, carpets, and cotton wool filter nozzles. Different fiber thicknesses are used for different products; for example, the thickness for sanitary products is 1.5-2.5, ground fabrics is 5-10, and their lengths range from 1.5 to 200.0 mm, depending on the specific application.
Polypropylene staple fibers can be divided into cotton type, wool type, carpet type, and medium and long types according to natural fiber specifications. They can be spun purely or blended with natural or other fibers in varying proportions to make sliver, fabric, and felt.
Polypropylene staple fibers are mainly used in needle-punched carpets, automotive interiors, non-woven fabrics, ropes, decorative materials, medical and sanitary products, etc. Short fiber, also called cut fiber, are chemical long fiber bundles cut or broken into fibers matching various natural fiber lengths. Natural fibers like whiskers and asbestos can also be used. Short fiber lengths are generally 35 to 150mm, classified into cotton type, wool type, carpet type, and medium and long types. They can be spun purely or blended with natural or other fibers to make sliver, fabric, and felt.
Polypropylene staple fibers are characterized by low density, light weight, and the ability to float on water. They have high strength and strong tensile strength and possess certain acid and alkali resistance. These fibers are corrosion-resistant and do not suffer in sea water. Polypropylene staple fibers have low hygroscopicity and almost no moisture absorption, making them environment-friendly and pollution-free products.
Polypropylene products provide good bulk and coverage, are abrasion-resistant, color-fast, and quick drying. They have low static, resist deterioration from chemicals, mildew, perspiration, rot, and weather, and are stain and soil resistant, and sunlight resistant. Polypropylene garments wick body moisture from the skin, are very comfortable, and lightweight.
Polypropylene fiber is made from isotactic polypropylene chips through the melt spinning process to form filaments. These filaments or fibers are then solidified by air or water quenching. Following this, a spin finish is applied and collected in cans. The fibers are stretched several times in a chemical hot bath, relaxed, and crimped to be suited for various spinning systems.
Polypropylene staple fiber is used to manufacture air filters, water filters, and other industrial fabrics, and is also used for woven carpets, non-woven carpets, upholstery, and carpet backing.
Polypropylene staple fibers offer superior features due to their lowest specific gravity, resulting in better relative coverage, high dimensional stability, excellent recovery properties (elasticity and resiliency), low thermal conductivity, the lowest static charge, and chemical inertness. The denier range of PP Fiber is 1.5D to 70D.
Geotextiles are permeable fabrics that, when used with soil, can separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three forms: woven, needle punched, or heat bonded. Higher Breaking Tenacity and higher Breaking Elongation are prerequisites for good quality geotextiles. UV stabilization is done using a high-quality HALS-based UV Stabilizer in desired proportions to meet domestic and global standards.

Virgin Polypropylene Staple Fiber is used in spinning yarns, filler fabrics, geotextiles, automotive floor carpets, thermal bonded fabrics, insulations, carpet and filter fabrics, felts, non-woven carpets, building construction, and RCC.
Other applications include reinforcing concrete using short cut lengths for RCC building construction and making cement sheets, tiles, and pipes, enhancing the strength of the concrete or RCC. Fiber Reinforced Concrete (FRC) is Portland Cement concrete reinforced with thousands of randomly distributed small fibers, improving properties in all directions. Polypropylene fibers in 0.5% to 1% are normally used. Common lengths for various applications include 6, 12, and 20 mm with specific deniers for each use. Polypropylene is also used in apparel (activewear, sportswear, socks, thermal underwear, lining fabrics).
Spunbond non-woven fabrics, also known as filament non-woven fabrics, are made by extrusion spinning, stretching, meshing, and bonding after melting polypropylene raw materials. They have a short process, low cost, high productivity, excellent performance, and a wide range of uses. Such fabrics are widely used in various production and life fields, including disposable medical and sanitary products, disposable anti-fouling clothing, agricultural cloth, furniture cloth, shoe industry linings, etc.
First, analyze the elongation at break. It's often measured using the suspension method, calculated by the strong force, which means the weight of a single fiber suspension equals its breaking strength. Research shows polyester's elongation at break is 30-40%, polypropylene is greater than polyester, nylon is 18-45%, and vinylon is 12%-25%. From these data, it's hard to rank them definitively without specific context.
Second, analyze recovery. Nylon has above 90% recovery rate at 10% elongation, which is characteristic for nylon. For others, polypropylene is better than polyester, and vinylon is relatively poor.
Finally, analyze wear resistance, a key performance metric for centrifuge screens. Polyester and nylon have good wear resistance, followed by polypropylene, and then vinylon.
