Abstract

The invention discloses a method for preparing non-ironing multifunctional blended yarn by utilizing an electrostatic spinning nanotechnology. The method comprises the following steps of S1, performing opening picking and carding processes on long stapled cotton; S2, stirring and dissolving low-melting-point polyester by using a solvent, and adding a functional material to prepare a spinning solution; S3, performing two drawing processes on cotton bundles obtained in the step S1, performing electrostatic spinning on the spinning solution in a primary drawing process, coating and mixing electrostatic spinning micro-nano fibers in long stapled cotton in the primary drawing process, and further uniformly mixing the electrostatic spinning micro-nano fibers and the long stapled cotton in a secondary drawing process to obtain composite cotton bundles; and S4, sequentially carrying out roving, spinning, sizing, weaving and post-treatment processes on the composite cotton bundles to obtain themultifunctional blended yarn. By the adoption of the process, the non-ironing performance and the mechanical property of the yarn can be improved, and meanwhile due to the fact that functional materials are added in the electrostatic spinning process, the fabric has corresponding functional attributes.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing non-ironing multifunctional blended yarns by using electrospinning nanotechnology. Background technique [0002] Electrospinning is a special fiber manufacturing process in which a polymer solution or melt is jet-spun in a strong electric field. Under the action of an electric field, the droplet at the needle will change from a spherical shape to a conical shape (that is, "Taylor cone"), and extend from the tip of the cone to obtain a fiber filament. Electrospinning technology is the most economical industrialization technology used to prepare nanometer to micrometer polymer fibers. The micro-nano fibers prepared by electrospinning technology have large specific surface area, high porosity, easy size control, and easy surface functionalization. (such as surface coating, surface modification) and other characteristics have important application...
