Abstract

The invention discloses a dyeing and finishing treatment method for all-cotton suede-like broad width fabric. The method comprises the following steps: pre-treatment, galling, cropping, printing/dyeing, and post-treatment in order to obtain the finished product fabric; during a galling process, a front surface and a back surface are subjected to the galling and cropping processes, the galling andcropping processes are alternative carried out, in the galling process of the front surface and the back surface, a right surface of the fabric is a cylinder roller, the back surface of the fabric isa negative-pressure air suction device, during a cropping process, carbon brushes with an even number is added at 10-30 cm before a cloth-holding cutter, and the rotation direction of the adjacent twocarbon brushes is opposite. The fabric has abundant feeling, and each index is qualified.

Description

technical field [0001] The invention belongs to the technical field of textile fabric processing, and in particular relates to a method for dyeing and finishing cotton suede wide fabrics. Background technique [0002] Cotton fabrics have always been favored by people because of their good skin affinity and moisture absorption, especially in winter. Due to the relatively cold weather in winter, when the human skin is just in contact with the sheet or quilt cover, it will produce an instant cold feeling and irritate the skin. Therefore, the current conventional method is to sand the fabric to reduce the cold feeling of instant contact, so that the human body does not feel so cold; however, after the fabric is sanded, the fibers and yarns are severely damaged, and the resulting fine hairiness still remains. In the gaps between yarns or fibers, the fabric is prone to shedding during use, which affects the sleeping environment in the bedroom. [0003] In order to obtain the woo...
