Problems solved by technology

[0006] CN102560896A discloses a method and device for preparing a composite functional membrane with a nanofiber layer. The patent is that the nonwoven fabric prepared by the spunbond module becomes the supporting layer of the composite membrane, and the nanofiber prepared by the electrospinning module becomes the composite membrane. The functional layer compounding, preparation of double-layer or multi-layer functional film material, but this method has a small range of applications, the final composite functional film cannot be processed to form textiles, and the original properties of wool during the melt spinning process are easily affected

Abstract

The invention relates to a preparation method of an electrostatic spinning nanofiber / wool antibacterial yarn. The preparation method comprises the following step of performing a subsequent yarn forming work procedure on a web containing nanofiber to obtain the nanofiber / wool antibacterial yarn. A traditional spinning technology and an electrostatic spinning technology are combined; and the prepared nanofiber / wool composite yarn has the antibacterial performance and effects. Compared with a wool antibacterial after finishing method, the preparation method has the advantages that the operation process is simple; the cost is low; safety and environment protection are realized; and the prepared yarn has good antibacterial effects and permanent performance.

Description

technical field [0001] The invention belongs to the field of preparation of antibacterial yarns, in particular to a preparation method of electrospun nanofiber / wool antibacterial yarns. Background technique [0002] With the improvement of people's living standards and the development of textile technology, the traditional wearing properties of textiles, such as warmth retention and comfort, can no longer meet people's needs, and consumers are putting forward higher and higher requirements for their functionality. Textile fabrics are developing towards functionalization. [0003] Traditional fibers have thicker diameters, lower aspect ratios, and smaller specific surface areas. In order to give certain functionality to traditional fiber products, it can be obtained by physical and chemical modification of fiber surface, adjustment of fiber yarn components and process, change of fabric structure and addition of certain functional substances. These have the disadvantages of ...
