Problems solved by technology

[0004] Based on the excellent properties of special-shaped fibers, many fabrics often use the spunbond method to polymerize the polymer raw materials through high-temperature wire drawing and polymerize them, and then use the hot rolling method to bond them into cloth. The process is simple, the output is large, and it is non-toxic and harmless to the human body. It is widely used. Used in agricultural production, daily necessities, industrial production, and construction water conservancy industries, in the process of making oil-absorbing felt materials from special-shaped fibers, in order to obtain a larger specific surface area to enhance the adsorption effect of the material, it is often only possible to use a higher denier. Fine fibers cause the finished product of non-woven fabrics to be too soft and wear-resistant. Therefore, the present invention proposes a special-shaped fiber for making oil-absorbing felts with a large specific surface area, good adsorption effect, toughness and wear resistance.

Abstract

The invention discloses a processing technology for making special-shaped fibers for oil-absorbing felts, which comprises the following steps: (1) cleaning, drying, crushing, sieving, soaking in a treatment solution, ultrasonic treatment, and then cleaning and drying the loofah scoop; (2) Mix polypropylene resin, loofah powder, filler, compatibilizer, light stabilizer, flame retardant, and surfactant evenly to obtain a compound; (3) melt and extrude the compound to granulate, dry, and obtain Modified polypropylene pellets; (4) The pellets are melt-extruded, filtered, and spun to obtain as-spun filaments; (5) The as-spun filaments are cooled, wound and drawn to obtain oriented filaments; (6) The oriented filaments are The full-drawn yarn is processed by a flat drawing machine, and the full-drawn yarn is wound, weighed and packaged to obtain special-shaped fibers for making oil-absorbing felts. The processing technology of the present invention is scientific and reasonable, and can be implemented on a large scale and industrially. The prepared special-shaped fiber not only has low density, small water absorption, high oil absorption ratio, but also has strong toughness and good wear resistance.

Description

technical field [0001] The invention relates to the field of special-shaped fiber materials, in particular to a processing technology of special-shaped fibers for making oil-absorbing felts. Background technique [0002] As an important material required in industrial production, navigation and daily life, oil-absorbing materials must have the following basic characteristics: lipophilic and hydrophobic, large specific volume and strong oil retention capacity. The raw materials generally used to make oil-absorbing materials are: polymer materials (polypropylene, polyurethane, polyethylene, etc.), inorganic materials (diatomaceous earth, pumice, etc.) and fibers (straw, wheat straw, wood chips, reeds, etc.). [0003] Special-shaped fibers, also known as special-shaped cross-section fibers, refer to fibers of various cross-sectional shapes produced by spinnerets with non-circular holes in the textile forming process. The cross-sections of special-shaped fibers are mainly triang...
