Problems solved by technology

[0003] The existing seamless underwear dyeing method has high energy consumption and serious pollution. The water consumption per ton of cloth in most dyeing factories is above 1:100
Most dyeing processes adopt the intermittent production of dyeing machines from pre-treatment to soft finishing. The liquor ratio is about 1:30, and the process is backward. Large amount of repair, more water consumption; more caustic soda used, high COD of wastewater, sewage treatment can not meet the discharge standards

Embodiment 1

[0036] Example 1: A cotton / nylon / spandex seamless thermal underwear set

[0037] The seamless weft knitting technology is used for one-time weaving. The fiber ratio of the fabric composition is as follows: in terms of weight percentage, cotton count 40 veil: 50%; nylon PA6 DTY 78dtex filament: 45%, the ratio of PA6 DTY 78dtex filament The requirements for false twist texturing are S and Z twist directions, and the fibers in S and Z twist directions are used for weaving. Spandex PU 22dtex: 5%, PA6 DTY 78dtex filament and spandex PU 22dtex are combined to form a covered yarn.

[0038] After the clothes are washed, adjust the water temperature to 40°C, and add 3g / L of rapid oxygen bleaching agent 590A and 7ml / L of 27.5% H 2 o 2 , bath ratio: 1:8, water temperature rises at a rate of 1.5°C / min to 98°C~100°C, keeps warm for 20 minutes; cools down to 80°C, drains liquid; enters water, adjusts water temperature to 40°C, and adds 0.5% of For glacial acetic acid solution, the water t...

Embodiment 2

[0039] Embodiment 2: A kind of modal / nylon / spandex seamless bikini underwear

[0040] The seamless weft knitting technology is used for one-time weaving. The fiber ratio of the fabric composition is as follows: by weight percentage, Modal veil of Ne 50: 70%; nylon PA6 DTY 30dtex filament: 27%, and the length of PA6 DTY 30dtex The requirements for the false twist deformation processing of silk are two twist directions of S and Z, and weaving is carried out with fibers of two twist directions of S and Z. Spandex PU 22dtex: 3%, PA6 DTY 30dtex filament and spandex PU 22dtex are combined for coating yarn.

[0041] After the clothes are washed, adjust the water temperature to 30°C, and add 3g / L of rapid oxygen bleaching agent 590A, 1g / L of anti-wrinkle agent ACA, and 3ml / L of 27.5% H 2 o 2 , 2.5g / L degreaser, 1.5g / L scouring enzyme, liquor ratio: 1:8, water temperature rises to 98°C at a rate of 1.5°C / min, keeps warm for 20 minutes; cools down to 80°C, drains ; Inlet water, adjus...

Embodiment 3

[0042] Embodiment 3: A kind of bamboo fiber / nylon / spandex seamless bra

[0043] The seamless weft knitting technology is used for one-time weaving. The fiber ratio of the fabric composition is as follows: by weight percentage, bamboo fiber 40 British count veil: 80%; nylon PA6 DTY 30dtex filament: 15%, and PA6 DTY 30dtex filament The requirements for the false twist texturing process are S and Z twist directions, using S and Z twist fibers for weaving, spandex PU 22dtex: 3%, PA6 DTY 30dtex filament and spandex PU 22dtex to form a covered yarn .

[0044] After the clothes are washed, adjust the water temperature to 30°C, and add 3g / L of rapid oxygen bleaching agent 590A, 1g / L of anti-wrinkle agent ACA, and 5ml / L of 27.5% H 2 o 2 , 2.5g / L degreasing agent, 3g / L scouring enzyme, bath ratio: 1:8, water temperature rises to 98°C at a rate of 1.5°C / min, keeps warm for 30 minutes; cools down to 80°C, drains; Enter water, adjust the water temperature to 40°C, add 0.5% glacial aceti...

Abstract

The invention relates to an energy and water saving dyeing method for a seamless underwear. A seamless weft knitting weaving technology is used for achieving one-off weaving forming of the seamless underwear. The dyeing and finishing process of the seamless underwear after being woven includes oxygen bleaching by the liquor ratio of 1: 8-10, dyeing by the liquor ratio of 1: 12-15 and soaping by the liquor ratio of 1: 8-10. By means of the energy-saving dyeing and finishing technology of non-caustic-soda oxygen bleaching process, one-bath one-step dyeing process and biological enzyme soaping process, one-time accurate dyeing is achieved, one-bath one-step completion is achieved, processing time is shortened, and sewage discharge and treatment are reduced.

Description

technical field [0001] The invention relates to an energy-saving and water-saving dyeing method for seamless underwear. Background technique [0002] Energy conservation, emission reduction, consumption reduction, and environmental protection are the strategies to realize the sustainable development of the textile industry. The printing and dyeing link is the top priority for the entire textile industry to achieve energy conservation and emission reduction.
