Embodiment 1

[0040] A kind of dyeing process of mulberry silk fabric, comprises the following steps:

[0041] (1) Pretreatment: Pretreatment of mulberry silk fabrics, specifically: use urea 1g / L, phosphorus-free neutral deoiling spirit TF-104M 4.5 g / L, sodium dodecylbenzenesulfonate 1 g / L , 60% hydrogen peroxide 2 g / L, oxidative desizing agent OS 0.8 g / L, treated in a 30°C water bath for 2-3 min, the bath ratio was 20:1, and then heated up in the water bath at a rate of 2.5°C / min. After the temperature rises to 90°C, keep at this temperature for 30-40min, then the temperature of the water bath is lowered at a rate of 1.5°C / min, when the temperature drops to 60°C, discharge the treated wastewater, and then re-inject clean water at room temperature Rinse until the lotion is neutral, and finally dry;

[0042] (2) Pre-setting: Pre-setting the mulberry silk fabric through a pre-setting machine. During the pre-setting process, the setting temperature is 160°C, the speed is 20m / min, and the over...

Embodiment 2

[0056] A kind of dyeing process of mulberry silk fabric, comprises the following steps:

[0057] (1) Pretreatment: pretreatment of mulberry silk fabrics, specifically: use urea 1.2g / L, phosphorus-free neutral deoiling spirit TF-104M 5 g / L, sodium dodecylbenzenesulfonate 1.2 g / L L, 60% hydrogen peroxide 2.5 g / L, oxidative desizing agent OS 1g / L, treated in a 30°C water bath for 2-3 min, the bath ratio was 20:1, and then heated up in the water bath at a rate of 2.5°C / min. After the temperature rises to 90°C, keep it at this temperature for 35 minutes, then lower the temperature of the water bath at a rate of 1.5°C / min, and when the temperature drops to 60°C, discharge the treated waste water, and then re-inject clean water to rinse at room temperature until The lotion is neutral and finally dried;

[0058] (2) Pre-setting: Pre-setting the mulberry silk fabric through a pre-setting machine. During the pre-setting process, the setting temperature is 165°C, the speed is 25m / min, a...

Embodiment 3

[0072] A kind of dyeing process of mulberry silk fabric, comprises the following steps:

[0073] (1) Pretreatment: Pretreatment of mulberry silk fabrics, specifically: use urea 1.5g / L, phosphorus-free neutral deoiling spirit TF-104M 5.5 g / L, sodium dodecylbenzenesulfonate 1.5 g / L L, 60% hydrogen peroxide 3 g / L, oxidative desizing agent OS 1.2 g / L, treated in a 30°C water bath for 2-3 min, the bath ratio is 20:1, the water bath is then heated up, the heating rate is 2.5°C / min, When the temperature rises to 90°C, keep it at this temperature for 40 minutes, then cool down the water bath temperature at a rate of 1.5°C / min, when the temperature drops to 60°C, discharge the treated wastewater, and then re-inject clean water to rinse at room temperature until the lotion is neutral, and finally dry;

[0074] (2) Pre-setting: Pre-setting the mulberry silk fabric through a pre-setting machine. During the pre-setting process, the setting temperature is 170°C, the speed is 30m / min, and t...

Abstract

The invention provides a dyeing process of mulberry silk fabrics. The dyeing process comprises the steps of: pretreatment, presetting, low-temperature freezing treatment, dyeing, soaping, color fixing, after finishing, drying, setting, calendering and winding. The dyeing process provided by the invention has the advantages that the step of low-temperature freezing treatment is added, so that the modifying treatment is carried out on the properties of the mulberry silk fabrics fundamentally; a salt-free dyeing additive is added in the dyeing procedure, so that the use of inorganic salts is reduced on the premise of guaranteeing the dyeing effect; the soaping and color-fixing processes are added, so that the dyeing firmness is good; in the color fixing process, environment-friendly formaldehyde-free TCD-R is adopted, and the fiber is dried in a step-by-step manner after color fixation, so that the firmness of the fiber is greatly improved; the after-finishing process is added, so that the color firmness and softness of the fabrics are improved and increased, the roughness of the fabrics is reduced, and further the fabrics are fluffy and elastic.

Description

technical field [0001] The invention relates to a dyeing process of mulberry silk fabrics. Background technique [0002] Fibers are divided into chemical fibers and natural fibers. Chemical fibers are fibers with textile properties that are made from natural polymers or artificially synthesized polymers through the processes of preparing spinning dope, spinning and post-treatment. It has the advantages of light resistance, wear resistance, easy washing and drying, no mildew and no moths. Widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cords and parachutes, etc. Natural fiber refers to the fiber that exists and grows in nature and has textile value. Mulberry silk belongs to a kind of natural fiber, to be precise, it is a kind of natural protein fiber. Mulberry silk fiber is a high-grade textile raw material, the fiber is thin and soft, and has good strength and ...
