Embodiment 1

[0068] A method for patterning nylon fabrics, comprising the steps of:

[0069] (1) Laser pretreatment

[0070] according to figure 1 The pattern, using JG-13090 laser machine (Wuhan, Hubei, Jinyun Laser Co., Ltd.), using the photothermal characteristics of infrared laser to carry out full laser surface irradiation treatment on nylon fabric (10cm×10cm), set the laser machine at a fixed focal length The diameter of the spot is 0.5mm, the laser power is 12w, the laser scanning speed is 300mm / s, the scanning distance is 0.2mm, and the number of scanning is 1 time to obtain the laser pretreated nylon fabric;

[0071] (2) Dyeing

[0072] Use pomegranate peel dye to directly dye the nylon fabric after laser pretreatment, the dye dosage is 2% o.w.f, the bath ratio is 1: 30, the pH value of the dyeing bath is 3 (adjusted by citric acid), the dyeing is started at room temperature, and the heating rate is 1°C / min rises to a dyeing temperature of 98°C, heat-preserves and dyes for 60m...

Embodiment 2

[0074] Adjust the laser power in Example 1 to 4w, 8w, 12w, 16w, 20w, and the dyestuff consumption is 3% o.w.f. Other laser pretreatment and dyeing conditions are consistent with Example 1 to obtain the nylon fabric of laser pretreatment and pomegranate peel dyeing .

Embodiment 3

[0097] The dosage of the dye in Example 1 was adjusted to 1, 3, 4% o.w.f, and other laser pretreatment and dyeing conditions were kept the same as in Example 1 to obtain a nylon fabric with laser pretreatment and pomegranate peel dyeing.

Abstract

The invention discloses a method for patterning a chinlon fabric, and belongs to the technical field of textiles. The method for patterning the chinlon fabric comprises the following steps of (1) carrying out laser pretreatment: pretreating the chinlon fabric by adopting laser according to a designed pattern to obtain the chinlon fabric subjected to laser pretreatment, wherein the power of the laser is 8 to 12w; and (2) dyeing: dyeing pomegranate peel dye on the chinlon fabric subjected to laser pretreatment by adopting a direct dyeing method, and obtaining the patterned chinlon fabric according to the color difference formed by the dye-uptake difference of the fabric before and after laser pretreatment. According to the method for patterning the chinlon fabric provided by the invention, patterns drawn by computer aided design software are radiated to the fabric through the laser, after laser treatment, the dye absorption capacity of a laser area is improved, the maximum color difference is formed after 12w laser and 2-percent o.w.f pomegranate peel dye are selected for dyeing, and the clear pattern effect is shown on the surface of the fabric.

Description

technical field [0001] The invention relates to a method for patterning nylon fabric, which belongs to the technical field of textiles. Background technique [0002] With global warming and environmental pollution, the sustainability of textile processing has received increasing attention. Printing and dyeing is the most serious pollution in the textile industry. Traditional textile printing and dyeing production not only pollutes the environment, but also produces various harmful chemical substances, which endanger human health. Compared with the wet processing of traditional printing and dyeing, the advantages of laser technology as a dry process have positive significance for reducing wastewater discharge and energy waste (Costin and Martin, 1999; Hung et al., 2020; Kane et al., 2020; Unal et al., 2020). The dyeing process of synthetic fabrics requires high temperature and energy, and the addition of chemicals and auxiliaries. Studies have shown that the absorption of...
