Problems solved by technology

People's demand for swimming trunks is also getting higher and higher, and there are certain requirements for the color of swimming trunks. Due to the general dyeing performance of swimming trunks prepared by polyester or nylon fabrics in the prior art, the dyeing effect is poor, making The finished swimming trunks after dyeing cannot be soaked in water for a long time without fading

Embodiment 1

[0019] A treatment method for improving the dyeing performance of fabrics for swimming trunks, including the following steps:

[0020] (1) Preparation of pretreatment agent: mix oxalic acid and malonamide uniformly according to the mass ratio of 2:0.6 and add them to the reactor, pass in inert gas to remove the air in the reactor, and then heat to 42°C in a water bath and keep warm 15min, then add 0.3% glycolic acid by mass of oxalic acid, stir evenly, then adjust the pH of the mixed system to 5.3

[0021] , Heat to 68°C, heat preservation and react for 2.5 hours, then cool and discharge to obtain a mixed product, and dissolve the obtained mixed product in an organic solvent at a mass ratio of 1:10 to obtain a pretreatment agent;

[0022] (2) Acid-base treatment: soak the polyester fabric in 2.5% sodium hydroxide solution for 30 minutes, then add citric acid solution to the sodium hydroxide solution until the pH of the solution reaches 6.3, stop the dripping. Continue to soak for 12...

Embodiment 2

[0033] A treatment method for improving the dyeing performance of fabrics for swimming trunks, including the following steps:

[0034] (1) Preparation of pretreatment agent: mix oxalic acid and malonamide according to a mass ratio of 2: 0.9 and add them to the reaction kettle, pass inert gas to remove the air in the reaction kettle, and then heat to 42°C in a water bath and keep warm 15min, then add 0.5% glycolic acid by mass of oxalic acid. After stirring evenly, adjust the pH of the mixed system to 5.5, heat to 68°C, keep the temperature for 2.5 hours, and then cool and discharge to obtain the mixed product. 1:10 mass ratio is dissolved in organic solvent to obtain pretreatment agent;

[0035] (2) Acid-base treatment: soak the polyester fabric in a sodium hydroxide solution with a mass fraction of 2.9% for 35 minutes, and then add citric acid solution to the sodium hydroxide solution until the pH of the solution reaches 6.3, stop the dripping. Continue to soak for 12 minutes, th...

Embodiment 3

[0046] A treatment method for improving the dyeing performance of fabrics for swimming trunks, including the following steps:

[0047] (1) Preparation of pretreatment agent: mix oxalic acid and malonamide uniformly according to the mass ratio of 2:0.7 and add them to the reaction kettle. Inert gas is introduced to remove the air in the reaction kettle, and then the water bath is heated to 42°C and kept warm. After 15 minutes, add 0.4% glycolic acid by mass of oxalic acid. After stirring evenly, adjust the pH of the mixed system to 5.4, heat to 68°C, keep the temperature for 2.5 hours, and then cool and discharge to obtain the mixed product. 1:10 mass ratio is dissolved in organic solvent to obtain pretreatment agent;

[0048] (2) Acid-base treatment: soak the polyester fabric in a sodium hydroxide solution with a mass fraction of 2.6% for 32 minutes, and then add citric acid solution to the sodium hydroxide solution until the pH of the solution reaches 6.3, stop the dripping. Cont...

Abstract

The invention discloses a treatment method capable of improving the dyeing performance of a shell fabric for swinging trunks, and relates to the technical field of clothes shell fabric. The treatmentmethod comprises the following steps: (1) preparation of a pretreatment agent; (2) acid-alkali treatment; (3) chinlon shell fabric pretreatment; (4) treatment with the pretreatment agent. By adoptingthe treatment method, the treated chinlon has higher dyeing performance, high color fixing degree and high uniformity, and the dyeing quality is guaranteed greatly.

Description

Technical field [0001] The invention belongs to the technical field of apparel fabrics, and specifically relates to a processing method for improving the dyeing performance of fabrics for swimming trunks. Background technique [0002] Swim trunks refer to clothing worn by men when swimming, diving or performing water-related activities. The shape is similar to underwear, but the fabric is usually different. With the advent of summer, the weather is getting hotter and even hotter. In order to escape the heat, swimming has become the main recreational activity in summer. Swimming pools, sea ice baths, reservoirs and even outdoor ponds are all places for people to swim. People’s demand for swimming trunks is also getting higher and higher, and there are also certain requirements for the color of swimming trunks. Because the swimming trunks made of polyester or nylon fabrics in the prior art have general dyeing performance, the dyeing effect is poor, so The finished swimming trunks...
