Problems solved by technology

[0008] 1) Due to the poor stability of the dispersion liquid of nanomaterials, especially sensitive to temperature, pH value, etc., the product quality is difficult to control due to the fluctuation of process parameters such as temperature and pH value in actual production
[0009] 2) The fastness of nanomaterials attached to the surface of textiles mainly depends on the bonding effect of adhesives, which is often difficult to last and stabilize

Embodiment 1

[0038] The preparation of embodiment 1 nano antibacterial textile

[0039] 1. Textile specifications

[0040] Black 100% pure ramie plain cloth; Weight: 140g / m 2 ; Yarn special number: 21×21; Warp and weft density: 236×236; Width: 140cm.

[0041] 2. Selection of nano antibacterial agent

[0042] There are many kinds of nanomaterials that can be used in antibacterial textiles, such as nano-titanium oxide, nano-zinc oxide, nano-silicon oxide, and nano-zirconia. In order to improve the antibacterial properties of these nanomaterials, these nanoantibacterial agents are often compounded with silver or rare earths to make composite antibacterial agents, such as rare earth-activated nano-zinc oxide antibacterial agents and nano-titanium oxide composite silver antibacterial agents.

[0043] Considering the cost performance, this embodiment selects a commercially available rare earth-activated nano-zinc oxide antibacterial agent, the main component of which is nano-ZnO pa...

Abstract

The nanometer functional fabric processing method is mainly to utilize ultrasonic technology in adding nanometer functional material to fabric to prepare nanometer functional fabric. The fabric, which may be pre-humidified, is fed to finishing machine and treated under the action of ultrasonic wave field inside treating bath with nanometer functional material dispersed in water in advance, so that the nanometer functional material is embedded into fine cracks, furrows and holes of fabric and fiber owing to the cavitaion effect and other physical and mechanical effects of ultrasonic wave inside liquid. Through further water washing, mounting, softening and stoving, firm and soft nanometer functional fabric is ultimately prepared.

Description

technical field [0001] The invention relates to a textile finishing technology, in particular to a finishing and processing method of nano functional textiles. Background technique [0002] At present, the processing methods of nano functional textiles at home and abroad mainly include filling method and finishing method. [0003] 1. Filling method [0004] The filling method is a method of adding nano-antibacterial composite materials into chemical fibers to obtain various nano-functional chemical fibers, and then making these chemical fibers into functional textiles. The main methods are grafting method, ion exchange method, wet spinning method, melt blending spinning method and composite spinning method. [0005] 2. Finishing method [0006] The post-finishing method refers to the method of impregnating or coating textiles with nanomaterial dispersions and resins to endow textiles with specific functions. The commonly used methods are surface coating method, resin fin...
