Embodiment 1

[0043] In this embodiment, the wool of the woolen fabric is dyed into a light color with a reactive dye, and the consumption of the dye is 0.5% (o.w.f). The woolen fabric in this embodiment is a wool jersey with spandex, specifically the 72N / 1 Yangtze shrink-resistant wool (compact spinning 18.9 fineness)+20D low-temperature type LYCRA (Lycra) produced by Shanghai Jialinjie Textile Co., Ltd. ) fully lined with spandex single jersey, the weight is 140g / m 2 , the width is 150cm, the weight is 20 kilograms, and the wool content is 95.6wt%.

[0044] In a jet dyeing machine, the method of dyeing the woolen fabric includes the following steps:

[0045] a 2 ) pretreatment process: inject industrial soft water into the jet dyeing machine at a bath ratio of 1:15, put the woolen fabric into the jet dyeing machine, record the water level at this time, add degreaser and sodium sulfate, and the amount of degreaser is Every 1 liter of water 2g, the consumption of sodium sulfate is 3% (o....

Embodiment 2

[0051] In this embodiment, the wool of the woolen fabric is dyed into a neutral color with a reactive dye, and the consumption of the dye is 2% (o.w.f). The wool fabric is wool single jersey with spandex, specifically 72N / 1 Yangtze shrink-resistant wool (compact spinning 18.9 fineness) + 20D low temperature type LYCRA (Lycra) full lined spandex jersey produced by Shanghai Jialinjie Textile Co., Ltd. , the weight is 140g / m 2 , the width is 150cm, the weight is 20 kilograms, and the wool content is 95.6wt%.

[0052] In the jet dyeing machine, the method for dyeing the woolen fabric comprises the following steps:

[0053] a 1 ) pretreatment process: inject industrial soft water into the jet dyeing machine at a bath ratio of 1:15, put the woolen fabric into the jet dyeing machine, record the water level at this time, add degreaser and sodium sulfate, and the amount of degreaser is Every 1 liter of water 1.5g, the consumption of sodium sulfate is 5% (o.w.f), then add sodium carb...

Embodiment 3

[0060] In this embodiment, the wool of the woolen fabric is dyed into a dark color with a reactive dye, and the consumption of the dye is 4% (o.w.f). The wool fabric is wool single jersey with spandex, specifically 72N / 1 Yangtze shrink-resistant wool (compact spinning 18.9 fineness) + 20D low temperature type LYCRA (Lycra) full lined spandex jersey produced by Shanghai Jialinjie Textile Co., Ltd. , the weight is 140g / m 2 , the width is 150cm, the weight is 20 kilograms, and the wool content is 95.6wt%.

[0061] In a jet dyeing machine, the method of dyeing the woolen fabric includes the following steps:

[0062] a 1 ) pretreatment process: inject industrial soft water into the jet dyeing machine at a bath ratio of 1:15, put the woolen fabric into the jet dyeing machine, record the water level at this time, add degreaser and sodium sulfate, and the amount of degreaser is Every 1 liter of water 1g, the consumption of sodium sulfate is 2% (o.w.f), then add sodium carbonate 0.6...

Abstract

The invention discloses a dyeing method of a wool textile with low energy consumption and low damage, comprising the following procedures: a pre-processing procedure, a dyeing procedure, an acid neutralizing procedure and an insect prevention procedure; the pre-processing procedure is carried out in a pre-processing fluid with a pH value of 8.2 to 8.7; the dyeing procedure is carried out in a dyeing fluid with a pH value of 4.5-7; and the acid neutralizing procedure is performed in a post-processing fluid with a pH value of 4-6. The invention further relates to a wool fabric manufactured according to the dyeing method of the wool textile with low energy consumption and low damage. Due to the adoption of the dyeing method disclosed by the invention, the dyeing temperature can be reduced from 98 DEG C in the conventional technique to 80-90 DEG C, the strength loss rate of the wool during the dyeing stage can be controlled at about 30%, and the dyed wool textile has good cloth surfaces and good color fastnesses.

Description

technical field [0001] The invention relates to the field of dyeing and finishing, in particular to a fabric dyeing method, in particular to a wool fabric dyeing method with low energy consumption and low damage. The invention also relates to a wool fabric. Background technique [0002] The traditional wool dyeing process requires a long boiling process. The boiling dyeing process is easy to cause damage and yellowing of the wool fabric, which affects the surface style of the fabric. At the same time, the boiling dyeing process does not meet the needs of energy conservation. [0003] So far, the wool low-energy dyeing methods that have been proposed mainly focus on low-temperature dyeing, specifically: solvent auxiliaries method, urea method, formic acid method, biological enzyme treatment method, low-temperature dyeing auxiliaries method, ultrasonic dyeing method, low-temperature plasma dyeing method, etc. Body staining, redox system low temperature staining, etc. The so...
