Embodiment Construction

[0013] The following examples will help understand the present invention, but do not limit the content of the present invention.

[0014] First, the polyester fabric is irradiated with ultraviolet laser, the laser wavelength used is λ 1 And λ 2 The excimer laser has a pulse width of 20-40ns. Processing device such as figure 1 , The energy density of the laser is 50~150mJ / cm 2 , The size of the laser spot is 4mm×6mm, the polyester fabric is made of DTY, the processing area is 12cm×6cm, and the number of exposures is 5 to 10 times. The rotation speed of the motor used in the work platform is 200 rpm, and the entire processing area is scanned sequentially by the translation of the work platform. After being irradiated by excimer ultraviolet lasers of different wavelengths, the surface of the polyester fabric has regular undulating structures, which form a periodic undulating structure perpendicular to the fiber axis. picture 2-1 with Figure 2-2 . Irradiation of different laser wave...

Abstract

An ultravilet laser method for improving the dyeing property of cationic dye on polyester fabric, especially the terylene, features that the surface form and function groups of polyester fibre are changed by the ultraviolet excimer laser to generate the periodical wave structure for high dyeability.

Description

Technical field [0001] The present invention is an invention for changing the dyeing performance of polyester textiles, that is, a method for changing the dyeing performance of polyester textiles with cationic dyes by ultraviolet laser. The feature of the invention is a treatment method for changing the surface morphology and surface groups of polyester textiles through excimer ultraviolet lasers to obtain cationic dye dyeability. It is especially suitable for polyester fabrics, which can increase the range of dyes for this type of fabric. Ultraviolet laser irradiates polyester textiles to form periodic undulating structures perpendicular to the fiber axis on the surface of the fibers in the textiles. This phenomenon also has great scientific value in the study of the interaction between lasers and polymer materials. Background technique [0002] Polyester textiles are widely used in industrial and agricultural production and people's daily life. Due to the lack of groups in the ...
