Description
Technical Field
The invention relates to the technical field of dyeing, in particular to a method for improving fluorescence Huang Ying luminosity of a flame-retardant knitted fabric.
Background
The fabric has special warning sign after being dyed by fluorescent yellow dye, and the warning effect is widely applied. The fluorescent yellow fabric is endowed with flame retardant property, labor protection function is increased, and application fields are expanded. Internationally, the common textile fluorescence detection standards include European standard EN ISO 20471:2013, high visibility clothing-test method and requirement, american standard ANSI107-2020, safety clothing and accessories for high visibility, which are national standards in the United states, and fluorescence of the fluorescent yellow fabrics can reach the standard and be exported. However, in the flame retardant process, the fluorescence was severely attenuated, and the fluorescence of the fabric was again attenuated after continuous sun-drying for 20 hours and 40 hours after flame retardant. Therefore, the fluorescence degree of the prepared fluorescent yellow fabric can pass through European and American standards, and the fluorescent yellow fabric can be exported to foreign countries and is a technical problem to be solved.
There are two types of fluorescent yellow dyes commonly used: one is direct fluorescent yellow 7GFF and the other is active ramalin fluorescent yellow FL produced by desida. Because of the poor fastness of the direct fluorescent yellow after flame retardance, the flame retardant fabric is mainly used for dyeing the fabric, and the flame retardant fabric generally selects active ramalin fluorescent yellow FL.
Common dyeing methods are pad dyeing, dip dyeing and cold dyeing. Pad dyeing is to pad dye, dry and pad alkali agent to evaporate color rapidly, the dye utilization rate is highest, but if pad dyeing is adopted, the knitted fabric can generate serious stretching deformation, and no knitting open width continuous steaming equipment is provided in China. And dip dyeing is adopted, the time for fixation by adding alkali is prolonged, the temperature is increased, the dye is severely hydrolyzed, the dye utilization rate is low, and the cost is increased. In addition, the price of the ramalin fluorescent yellow dye FL is 50 times that of the common reactive dye. By adopting cold pad dyeing, padding dye can generate tension on knitted fabric, the fabric is stretched, indexes such as gram weight, breadth, shrinkage and the like of the fabric are influenced after deformation, and particularly the density of the stretched fabric is reduced, the fluorescence is reduced, and the fabric is not easy to pass European and American standards. Thus, there is a need for a method that can increase the fluorescence Huang Ying luminosity of flame retardant knitted fabrics to enable the fluorescent yellow fabrics to pass the European and American standards.
