Device for continuously and quickly detecting dry rubbing fastness of dyed fabric

Abstract

The invention relates to the related field of dyes, and discloses a device for continuously and quickly detecting the dry rubbing fastness of a dyed fabric, wherein the device comprises a detection box, a detection cavity is formed in the detection box, a white cloth inlet and outlet which is through left and right and communicates with the detection cavity is formed in the detection box, and a top electromagnet cavity is formed in the upper side of the detection cavity; a limit groove is communicated between the top electromagnet cavity and the detection cavity, and a rotary disc cavity is arranged behind the detection cavity. According to the device, the dry rubbing fastness of a plurality of dyed fabric samples can be detected, staining conditions are left on white cloth at equal intervals, and subsequent rating of the fabric dyeing fastness is facilitated; According to the device, the height of a crochet hook is set to be the same as the thickness of the fabric, so that the devicecan realize single sampling of a single fabric sample, a plurality of samples are prevented from being grabbed due to friction between fabrics, and the reliability of a final result is ensured while the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field related to dyes, in particular to a continuous and rapid detection device for dry rubbing fastness of dyed fabrics. Background technique [0002] For the dry rubbing fastness of dyed fabrics, the existing technology is to grade the color fastness of dyes by rubbing the fabric with a white cloth and the fabric to be tested through the staining of the white cloth. Most of the existing devices are for automatic rubbing and detection of a single sample, which cannot Multiple samples are continuously and automatically tested for friction. At the same time, in the grasping of fabric samples, most of them are manually grasped and prevented. Due to the friction between fabrics, the deformation of fabrics and the electrostatic force between fabrics, it is difficult The way is to automatically grab the fabric. Contents of the invention [0003] The object of the present invention is to provide a continuous and rapid detectio...
