Embodiment 1

[0016] A processing technology for soft and anti-fading denim fabric, including biological enzyme pretreatment, dye solution preparation, dyeing, soaping, soft finishing, and shaping, the specific steps are:

[0017] Biological enzyme pre-treatment: put the denim base fabric in a laccase solution with a concentration of 2.1g / L, adjust the pH value to 5, treat it for 70 minutes at a temperature of 60°C and a bath ratio of 1:11, and adjust the pH value> 9.5, inactivate treatment for 10 minutes, wash with warm water, dry, and set aside. Denim fibers contain lignin, which can prevent dye molecules from entering the interior of the fiber, making the dyeing performance of the fiber poor. The laccase in this step It can remove the lignin in the base cloth, improve the dyeing performance, and the enzyme washing residue contains nutrients needed by aquatic animals and plants, which will not pollute water resources after being removed, thus protecting the natural environment;

Embodiment 2

[0024] A processing technology for soft anti-fading denim, the specific steps are:

[0025] 1) Put the denim base fabric into the laccase solution with a concentration of 3g / L, adjust the pH value to 4.8, treat it for 65 minutes at a temperature of 60°C and a bath ratio of 1:12, adjust the pH value to >9.5, and inactivate Treat for 11 minutes, wash with warm water, dry, and set aside. Denim fibers contain lignin, which can prevent dye molecules from entering the interior of the fiber, making the fiber's dyeing performance poor. The laccase in this step can remove the base fabric The lignin in the water improves the dyeing performance, and the enzyme washing residue contains nutrients needed by aquatic animals and plants, which will not pollute water resources after being removed, thus protecting the natural environment;

[0026]2) Take 7 parts by weight of caustic soda, 0.72 parts of penetrant, 0.15 parts of active polypeptide, 4.3 parts of indigo, 5.8 parts of sodium hydrosul...

Embodiment 3

[0032] A kind of processing technology of soft anti-fading denim, the specific steps are: put the denim base cloth into the laccase solution with a concentration of 3g / L, adjust the pH value to 5.5, and heat the denim at a temperature of 65°C and a bath ratio of 1:12 Treat under conditions for 60 minutes to inactivate enzymes; take 7 parts by weight of caustic soda, 0.8 parts of penetrant, 0.15 parts of active polypeptide, 5 parts of indigo, 5.5 parts of hydrosulfite, and 85 parts of water, stir evenly, and reduce at 52 ° C for 70 minutes, that is To obtain the dye solution; put the base fabric treated with biological enzymes into the dye solution, soak it for 15 minutes at a bath ratio of 1:28 and a temperature of 525°C, then dry it with a paddle car, and then oxidize it in the air for 70 seconds, and then thoroughly wash it with water. Rinse, dry naturally, and set aside; put the dyed denim into a soap boiling liquid containing 1.2g / L of soap powder and 2.2g / L of anhydrous so...

Abstract

The invention discloses a technology for processing a soft anti-fading denim fabric. The technology comprises the following specific steps: treating a base denim fabric in a laccase solution, performing enzyme deactivation, cleaning and drying; dipping the base fabric subjected to enzyme treatment in dye liquor, rinsing and airing; performing soap boiling on the dyed denim fabric in soap boiling liquor containing soap powder and anhydrous sodium carbonate; finishing in an aqueous solution of softening agent; and setting. The technology disclosed by the invention has the beneficial effects that xylogen in the base fabric can be removed by utilizing laccase in the processing technology disclosed by the invention, the dyeing property is improved, and water resources are not polluted after removal; the dye liquor can be uniformly distributed on the inner and outer layers of yarns in the dyeing process, a ring dyeing phenomenon is avoided, the diffusive force of the dye liquor is high, and the dyed fabric is high in dye-uptake and uniform in dyeing; and due to the soap boiling, the distribution condition of dyes on the denim fabric can be changed, partial flooding can be removed, the brightness of the denim fabric is increased, and the fading phenomenon of the denim fabric is improved.

Description

technical field [0001] The invention relates to the field of clothing fabrics, in particular to a processing technology for soft and fade-resistant denim. Background technique [0002] Denim is the only clothing category other than suits that has been popular for centuries and has no seasonality and can cross ethnicities, races, and genders. Classic denim or traditional denim refers to a denim fabric made of pure cotton yarn dyed with indigo as the warp yarn and natural cotton yarn as the weft yarn. Denim clothing is enduring because of its unique charms such as wear resistance, crispness, and comfort. Indigo denim can show different shades after washing. From the beginning of denim clothing in the 1970s to the present, denim has always been a popular element in the clothing industry, whether it is popular jeans or fashion shows. It is elegant and comfortable. The unique style of boldness, boldness and casualness is popular all over the world. [0003] The processing of d...
