Description
Technical Field
The invention relates to the technical field of spinning, in particular to a polyamide fiber containing plant functional porous molecular nests and a preparation method thereof.
Background
Polyamide (PA) fiber is synthetic fiber which realizes industrial production at the earliest in the world and is one of main varieties of chemical fiber, and the polyamide fiber has the advantages of low water absorption, good low temperature resistance, stable size, high strength, good toughness, wear resistance, shock absorption and the like, and is widely applied to the fields of aviation, textile, electrical appliances, sports and the like. Since polyamide fibers have excellent physical and textile properties, they have been developed rapidly and their yields have been the top of synthetic fibers for a long time. There are many varieties of polyamide fibers, and at present, polyamide 66 and polyamide 6 are mainly produced in the most industrialized mode and applied in the most extensive mode, and the yield of the polyamide fibers and the polyamide fibers accounts for about 98 percent of that of the polyamide fibers. Polyamide 66 represents approximately 69% of the total yield of polyamide fibres. The yield of polyamide 66 in China is about 60 percent, and the yield of polyamide 6 is about 40 percent. For historical reasons and different specific conditions in different countries, the western european countries such as the united states and the united kingdom and france have been dominated by the production of polyamide 66, while japan, italy, former soviet union and eastern european countries have been dominated by the production of polyamide 6, and some developing countries have also developed polyamide 6 fibers in large numbers. The production of polyamide fibres is predominantly continuous, but the production of staple fibres is gradually increasing. Therefore, it is important to develop a novel polyamide fiber.
Melt spinning, also known as melt spinning, is a molding method that takes a polymer melt as a raw material and is carried out by a melt spinning machine. Any polymer that can be melted or converted to a viscous state by heating without significant degradation can be spun by melt spinning. During melt spinning, the bulk polymer is melted in a screw extruder and then is fed into a spinning part, and is quantitatively fed into a spinning assembly through a spinning pump, and after filtration, the bulk polymer is extruded from capillary holes of a spinneret plate. The liquid strand is gradually solidified when passing through a cooling medium, and then is drawn into a filament at a high speed by a winding device below, the filament is a nascent fiber, and the nascent fiber is post-processed into a fiber. In order to prevent the filaments from being cooled too fast and difficult to form filaments, isothermal melt spinning is sometimes adopted, i.e. an isothermal chamber (called a spinning channel) is additionally arranged on a spinneret plate. The drawing speed of the winding device is very high, and can reach 1500-3000 m/min, depending on the material type and rheological property. The melt spinning has a large draw ratio and high productivity, and can be adjusted in a wide range. Polyester (polyester fiber), nylon (nylon) and polypropylene (such as polypropylene) fibers are all formed by melt spinning. An important requirement for melt spun polymers is a low melting point and no degradation upon softening by heat. The melt spinning does not need solvent, so the process is simple, the cost is low, and the problem of solvent recovery is avoided.
At present, the melt spinning nylon fiber does not have certain functionality, such as anti-inflammation, antibiosis and bacteriostasis, and the like, and the fluidity and the mechanical property of the spinning master batch are not good.
