Problems solved by technology

[0003] However, there are still many problems in the existing foam dyeing technology, such as large amount of dyeing materials, low color yield, poor level dyeing, large color difference between the front and back of the fabric, etc.
However, due to the poor hygroscopicity of nylon fabrics, the color yield after foam dyeing is low, the level dyeing property is poor, and the dyeing rate is poor.

Abstract

The invention discloses a method for enhancing the color depth of foam dyeing. In the invention, two kinds of nylon fabrics are foam dyed by adding a color enhancer without adding acid. The color enhancer is tetraethyl orthosilicate, deionized water and acetic acid Made of nano-silica hydrosol. The invention provides a foaming dye solution component and a dyeing process suitable for dyeing nylon acid dyes. While possessing conventional dyeing performance and color fastness, it has good level dyeing property, high color yield, and saves water, energy and dyeing at the same time. Chemical materials, green and environmental protection, continuous production, and greatly improve production efficiency, reduce costs, and have superior environmental benefits, resource benefits and economic benefits.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a foaming dye solution for improving the color depth of foam dyeing and a dyeing method thereof. Background technique [0002] Nylon fiber occupies an important position in synthetic fibers and is mainly used in clothing linings, outdoor products, carpets, industrial fabrics, etc. The demand is large, so its dyeing technology is also developing continuously. Acid dyes are the most widely used dyes in nylon dyeing, accounting for about 65% of the total nylon fiber dyes. The traditional acid dyeing is dyed by dyeing jigger, small batch, intermittent production, water consumption (bath ratio is 1:6-10), and large amount of sewage discharge. Nylon fabric is not suitable for continuous dyeing because of its poor hygroscopicity. The amount of liquid carried during padding is large, about 50%-70%. Swimming will occur during drying, and the fabric cannot be dyed even...
