Fine-diner full-dull nylon seamless swimsuit fabric dyeing method capable of dyeing ultra-dark color

Abstract

The invention discloses a fine-diner full-dull nylon seamless swimsuit fabric dyeing method capable of dyeing an ultra-dark color. The method comprises the following steps that 1, water enters a dyeing machine, the temperature is raised to 30 DEG C, a to-be-dyed fabric is put, the bath ratio is controlled at 1:(10-15), and running is carried out for 3 minutes; 2, a degreaser, a refining agent and a dyeing enhancer are added in sequence, running is carried out for 5 minutes, a dye is added, and running is carried out for 5 minutes; 3, the temperature is raised to 98 DEG C at the rate of 1.5 DEG C / minute, heat preservation is performed for 40 minutes, and drainage is carried out; 4, water inlet is carried out, the temperature is raised to 40 DEG C, heat preservation is performed for 40 minutes, and drainage is carried out; 5, water inlet is carried out, a dye-fixing agent is added, the temperature is raised to 75 DEG C, heat preservation is performed for 15 minutes, and drainage is carried out; 6, water inlet is carried out, a soaping agent is added, the temperature is raised to 75 DEG C, heat preservation is performed for 15 minutes, and drainage is carried out; 7, water inlet is carried out, a softening agent is added, the temperature is raised to 30 DEG C, heat preservation is performed for 15 minutes, the fabric is taken out from a cylinder, and dewatering is carried out; 8, the fabric is dried for 20 minutes at 85 DEG C. By adopting the method for dyeing, the color depth is increased by 30% or above compared with conventional dyeing, the dye consumption amount is reduced, the dyeing and washing color fastness is increased by 1 grade or above, and the color fastness of the fabric is improved.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing methods, in particular to a method for dyeing ultra-dark fine denier full-dull nylon seamless swimwear fabrics. Background technique [0002] The fine-denier full-dull nylon is made of seamless swimwear fabric, which is soft to the touch and light and thin. It is comfortable to wear, has good wear resistance, and has good natural anti-UV performance. It is very suitable for consumers to wear in outdoor activities such as seaside and beach. However, because the fabric is woven with fine denier nylon and is completely matted, the dyeing property of the fabric is poor when dyed, especially when making very dark colors, such as dark black, dark navy blue and other colors, the color dyeing depth is not good, and the dyeing residue There are many dyes in the medium, and the consumption of dyes is large, so the color fastness of the fabric is poor, which not only affects the product quality, but al...

Problems solved by technology

However, because the fabric is woven with fine denier nylon and is completely matted, the dyeing property of the fabric is poor when dyed, especially when making very dark colors, such as dark black, dark navy blue and other colors, the color dyeing depth is not good, and the dyeing residue There are many dyes in the medium, and the consumption of dyes is large, so the color fastness of the fabric is poor, which not only affects the product quality, but also increases a large number of washing processes, which consumes a lot of water and significantly increases the dyeing cost.
