Problems solved by technology

[0003] However, the existing PVA non-woven fabrics have the following problems after these steps of treatment: 1. PVA non-woven fabrics are easy to change color and have poor oxidation resistance when exposed to sunlight; 2. After repeated washing , easy to damage, short service life, poor wear resistance, easy to fade, poor color fixation; 3, does not have the effect of sterilization, flame retardancy and fragrance enhancement; 4, and the existing dyeing and finishing device cannot press the cloth Tight, to avoid it from being scattered and wrinkled during the dyeing and finishing process, and there is no device to drive the hanging basket to move up and down, which can not make the dyeing more uniform and more convenient to use. At the same time, there is no device to purify the gas, which will cause the gas to be discharged and pollute the environment

Embodiment 1

[0035] The present invention provides a kind of dyeing and finishing method of PVA non-woven fabric embroidery, and the dyeing and finishing method comprises the following steps:

[0036] 1) Sculpting and bleaching process: firstly inspect the original PVA non-woven fabric, turn it over and sew it, and then quickly wipe it on the hot metal surface. It carries out desizing treatment, then configures scouring working fluid, and controls the temperature at 45°C, puts the fabric that has been treated with liquid into a steamer, steams it, fully heats it for 3 times, and then puts the fabric in a mixture of hydrogen peroxide and caustic soda In the aqueous solution, heat at 30°C, rinse for 30 minutes, and finally configure 15mol / L sodium hydroxide solution, put the fabric into the sodium hydroxide solution for reaction, and the reaction time is 15 minutes;

[0037] 2) Dyeing process: Hang out the whole degummed PVA non-woven lace, put it on the hanging basket, and then add water, m...

Embodiment 2

[0044] The dyeing and finishing method of PVA non-woven fabric embroidery, the dyeing and finishing method comprises the following steps:

[0045] 1) Sculpting and bleaching process: firstly inspect the original PVA non-woven fabric, turn it over and sew it, and then quickly wipe it on the hot metal surface. It carries out desizing treatment, then configures scouring working liquid, and controls the temperature at 50°C, puts the fabric treated with liquid into a steamer to steam, fully hot washes 4 times, and then puts the fabric into a mixture of hydrogen peroxide and caustic soda In the aqueous solution, heat at 40°C, rinse for 50 minutes, and finally configure 20mol / L sodium hydroxide solution, put the fabric into the sodium hydroxide solution for reaction, and the reaction time is 30 minutes;

[0046] 2) Dyeing process: hang out the whole degummed PVA non-woven lace, put it on the hanging basket, and then add water, modified reactive dyes, sodium chloride 40g / L, and leveli...

Abstract

The invention discloses a dyeing and finishing method of a PVA non-woven fabric embroidery and a dyeing and finishing device thereof. The dyeing and finishing method includes scouring and bleaching, and comprises the following steps of: firstly, performing raw cloth inspection, cloth turning process and sewing process on the PVA non-woven fabric embroidery; then quickly wiping the PVA non-woven fabric embroidery on a hot metal surface while keeping the temperature of the metal surface to 750-850 DEG C; carrying out desizing treatment on the PVA non-woven fabric embroidery with hydrogen peroxide; then preparing a scouring working solution while controlling the temperature at 45-50 DEG C; putting the fabric having the liquid rolling treatment into a steam box for steaming and then rinsing for 30-50 minutes; finally, preparing 15-20 mol / L sodium hydroxide solution, and putting the fabric into sodium hydroxide solution to react for 15 to 30 minutes. By using the dyeing and finishing method, the cloth is dyed and finished, so that the cloth has good effects of oxidation resistance, wear resistance, sterilization, color fixation, flame retardance and fragrance enhancement. By using the dyeing and finishing device, dyeing color on the cloth is more even, which is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of PVA non-woven fabric embroidery, in particular to a dyeing and finishing method and a dyeing and finishing device for PVA non-woven fabric embroidery. Background technique [0002] PVA is polyvinyl alcohol, organic compound, white flaky, flocculent or powdery solid, odorless. Soluble in water (above 95°C), slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene dichloride Alcohol etc. Polyvinyl alcohol is an important chemical raw material for the manufacture of polyvinyl acetal, gasoline-resistant pipes and vinylon synthetic fibers, fabric treatment agents, emulsifiers, paper coatings, adhesives, glues, etc. The dyeing and finishing process of PVA non-woven fabric includes three steps, scouring, bleaching process, dyeing process and finishing process. [0003] However, the...
