Active dyeing method for velour fabric

Abstract

The invention belongs to the technical field of fabric production, and particularly relates to an active dyeing method for velour fabric. The method comprises the steps of firstly preparing dye liquor, mixing active dye with bioactive groups, 25% caustic soda, a foaming agent and a penetrating agent and foaming, steeping the velour fabric into the foamed dye liquor, soaping after washing with water, and then further washing with water; then drying the washed velour fabric via drying equipment; then putting the dry fabric into a dye vat again, adding glacial acetic acid and a dye-fixing agent,and taking the fabric out and washing the fabric with water; and at last testing the quality of the fabric after fixation, and packaging and putting the fabric in storage after quality testing is completed. According to the method, the velour fabric is dried by the drying equipment; when in drying, temperature is controlled to be 100-110 DEG C, the evaporating temperature of water is reached, andwhen the water is evaporating, fluff on the surface of the fabric is not affected, so that the completeness of the fluff on the surface of the velour fabric is ensured, and relatively large airing area is avoided.

Description

technical field [0001] The invention belongs to the technical field of fabric production, in particular to a reactive dyeing method for velvet fabrics. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people's requirements for clothing fabrics are increasing day by day, which puts forward new technological breakthrough indicators for manufacturers of such fabrics. In the selection of fabrics, the requirements of softness, comfortable feel and drape are the primary considerations in the selection of clothing materials. After complicated screening, polyester microfiber fleece fabric (also commonly known as velvet) has become one of the most widely used clothing materials, bringing people a very comfortable touch. The reason for choosing ultra-fine fiber is that the fineness of the fabric greatly reduces the stiffness of the silk, making the fabric feel extremely soft, and the thin fiber can also inc...

Problems solved by technology

[0003] At present, the most common flannelette production methods in the textile field are the steps of embryo refining, presetting, raising, shearing, dyeing, drying, and finished product setting. Due to the unique characteristics of velvet fabrics during dyeing, there are fluff on the surface; Therefore, in actual use, the dyed and washed velvet fabrics are dried by drying, so a large space is needed to dry the velvet fabrics, and the efficiency is low. If the existing drying equipment is used to dry , when the drying equipment is working for a long time, it is necessary to quickly pull out the velvet fabric that has passed the drying equipment to prevent the velvet fabric from being over-dried for too long and causing the fluff integrity of the velvet fabric. Pulling out from the drying equipment can not guarantee the complete drying of the velvet fabric, and the larger pulling speed can easily cause the wet velvet fabric to deform. In view of this, the invention provides a reactive dyeing method for the velvet fabric, which can reduce the Occupation of space ensures drying efficiency and at the same time guarantees the integrity of velvet fabrics
