experiment example 1

[0041] Experimental Example 1: Evaluation of fabric color strength (K / S) and color difference (CMCΔE)

[0042] In this experimental example, a spectrophotometer (Datacolor) is used to measure the color strength value related to the color depth of the fabric and the color difference value related to the color difference of the fabric on the fabrics of Examples 1 to 10, wherein The color strength value of the fabric is obtained by measuring the absorbance of the fabric under the irradiation of visible light with a wavelength of 400nm to 700nm, and the color difference value of the fabric is obtained by collecting 4 sampling points on the surface of the fabric for Lab value measurement and averaging The value is calculated, and the circumference diameter of each sampling point is between 9mm and 30mm. The measurement results of the fabrics of each embodiment are shown in Table 2.

Abstract

The invention discloses a method of uniformly dyeing a fabric. The method comprises the following steps. An ink-jet printing process is performed on the fabric, so that dye is configured on the surface of the fabric in a lattice point arrangement form. A spray wetting process is performed on the fabric, so that the fabric receives liquid drops. The fabric is subjected to a steaming fixation process, so that the dye is diffused on the surface of the fabric and is fixed on the surface of the fabric. The dyeing uniformity of the fabric can be improved by sequentially carrying out the ink-jet printing process, the spray wetting process and the steaming fixation process on the fabric.

Description

technical field [0001] The present disclosure relates to a method for uniformly dyeing a fabric, and more particularly to a method for uniformly dyeing a fabric treated by an inkjet printing process. Background technique [0002] Under the trend of globalization, the textile industry is facing strong competitive pressure. The textile industry must constantly develop new technologies and diversified products in order to face global competition. In the fabric manufacturing process, it is often necessary to dye the fabric, and the existing dyeing method is usually to place the cloth in a dyeing machine and soak it in a dye solution, so that the cloth can be dyed in the dyeing machine. However, this dyeing method is likely to cause waste of dye solution and excessive consumption of energy. However, if the inkjet method is used to dye the cloth, it is easy to cause uneven dyeing of the cloth. Therefore, how to reduce the waste of dye solution in the dyeing process and improve t...
