What is differential polypropylene fiber material?

differential polypropylene fiber is a kind of chemical fiber that is different from conventional polypropylene fiber in performance, appearance, function, etc., and has been widely used in many fields.

Polypropylene fiber, that is, polypropylene fiber, is a synthetic fiber spun from isotactic polypropylene obtained from propylene polymerization. The differential polypropylene fiber is to improve the conventional polypropylene fiber through chemical modification, physical deformation or the addition of functional additives, so that it has unique properties.

Performance differentiation

High strength: By improving the production process, improving the molecular orientation and other ways to enhance the tensile strength of the fiber. This kind of high strength differential polypropylene fiber is widely used in industrial ropes, fishing nets and other fields. For example, in deep-sea fishing operations, fishing nets made of high-strength polypropylene fibers can withstand greater tension, are not easy to break, improve fishing efficiency and extend the service life of fishing nets.

High modulus: Having a high modulus means that the fiber is rigid and not easy to deform. In some application scenarios with high dimensional stability requirements, such as geotextiles for the reinforcement of roads, DAMS and other infrastructure, the high-modulus differential polypropylene fiber can effectively prevent deformation caused by external force and ensure the long-term stability of the project.

Low shrinkage: conventional polypropylene fiber is easy to shrink when exposed to heat, while low shrinkage differential polypropylene fiber changes little in size at high temperatures. In the field of home textile, when it is used to make fabrics such as curtains and bedspreads, it can maintain its original shape and maintain a good appearance after washing and drying.

Appearance differentiation

Fine denier and ultra-fine denier: Denier is a unit of measurement of fiber thickness, fine denier and ultra-fine denier differential polypropylene fiber is thinner than conventional fiber. The fabric made of fine denier polypropylene fiber feels soft and delicate, close to natural fibers, and can be used to produce high-grade close-fitting clothing, which is comfortable to wear and has good drape. Ultra-fine denier polypropylene fiber can give the fabric high-density, so that it has wind, waterproof and other functions, while maintaining good air permeability, often used in the production of outdoor functional clothing.

Special section: Through the special spinneret, the production of cross section shape of non-circular fiber, such as triangle, three-leaf, hollow shape. The special section fiber can change the gloss, feel and covering properties of the fabric. For example, the differentiated polypropylene fiber with a three-leaf cross-section can give the fabric a silky luster; Hollow fiber because of the internal cavity, the thermal performance is greatly improved, often used in thermal underwear, sleeping bag and other products.

Functional differentiation

Flame retardant function: Flame retardants are added in the production process of polypropylene fiber to make it flame retardant. This flame-retardant differential polypropylene fiber is widely used in decorative fabrics in public places, clothing for children and the elderly, fireproof work clothes and other fields, which can effectively reduce the risk of fire and ensure the safety of personnel.

Antibacterial and mildew prevention function: Through chemical grafting or adding antibacterial agents, the fiber has the ability to inhibit the growth of bacteria and mold. It is widely used in home textile products, medical and health products, sports clothing and other fields with high health requirements, which can prevent fabrics from odors, discoloration and even damage due to microbial breeding, extend the service life of products, and protect the health of users.

Moisture absorption and perspiration function: The use of microporous structure on the fiber surface or special chemical modification, so that polypropylene fiber has good moisture absorption and perspiration performance. In the field of sports apparel, it can quickly absorb human sweat and conduct it to the surface of the fabric to volatilize, keep the skin dry, improve the comfort of wearing, so that athletes are not troubled by sweat during exercise, and maintain a good state of exercise.

Guangdong Modern High-tech Fiber Co., Ltd, founded in 2000 in Jieyang, Guangdong Province, is a high-tech enterprise focusing on the research and development, production and sales of new fiber materials. Since its establishment, the company has always focused on the field of polypropylene filament yarn, with continuous innovation and excellent quality, in the field of differentiated polypropylene fiber in-depth cultivation, remarkable results.
