Problems solved by technology

The color fastness to washing of the colored silk after being fixed by aldehydes is improved, but this method has obvious disadvantages: the color fixing will cause yellowing of the fabric, the hand feel is very bad, and the aldehydes have certain toxicity. Affect the environmental protection and safety of colored silk
In the prior art patent (2013102675613), phytic acid is used to replace commonly used industrial salt or industrial sodium bicarbonate as a leveling aid for dyestuffs, but it is not informed that the dyeing aid can play a role in color fixation and protein fibers. To the cross-linking effect, and the dyeing auxiliaries are made of multiple materials, which need to be purchased separately, with high cost and low work efficiency

Embodiment 1

[0029] Embodiment 1, a kind of green environmental protection processing method of high-quality natural color silk fabric, comprises padding, winding into cylinder, cold pile, doubling, weaving and refining, promptly, carries out following steps successively:

[0030] S1. Preparation of color-fixing treatment solution and color-fixing treatment:

[0031] 1.1, prepare color-fixing treatment liquid: deploy the aqueous solution that contains the phytic acid of 0.25g / L and the penetrant JFC of 1.8g / L (that is, contain 0.25g phytic acid and 1.8g penetrant JFC in every liter of aqueous solution water, remaining The amount is water), and the pH is adjusted to 7-9 (for example, about 8.14) by using a sodium hydroxide solution with a concentration of 10g / L, and the color fixing treatment solution is kept at 30°C (this temperature is maintained throughout the wetting process).

[0032] 1.2. Natural colored silk strands (select natural colored silk strands that have been reeled and shake...

Embodiment 2

[0045] Embodiment 2, a kind of green environmental protection processing method of high-quality natural color silk fabric:

[0046] S1. Preparation of color-fixing treatment solution and color-fixing treatment:

[0047] 1.1. Preparation of color-fixing treatment solution: Prepare an aqueous solution containing 105.6g / L of phytic acid and 4.5g / L of penetrant JFC, and adjust the pH to 3-5 with a concentration of 10g / L of sodium hydroxide solution (for example, about 3.37), the color-fixing treatment solution is heated to 55°C and kept warm.

[0048] 1.2. Control the bath ratio of natural colored silk strands / color-fixing treatment solution to 1:30 (kg / L), immerse natural colored silk strands in the color-fixing treatment solution, take out the colored silk after it is completely wet, press the liquid Roll out the excess color-fixing treatment solution with a rate of more than 40%, then wind the natural colored silk strands with liquid into a tube, place it in a cold stack for 1...

Embodiment 3

[0056] Embodiment 3, a kind of green environmental protection processing method of high-quality natural colored silk fabric, comprises the steps of winding into a cylinder, dipping, cold stacking, doubling, weaving and refining, that is, the following steps are carried out in sequence:

[0057] S1. Preparation of color-fixing treatment solution and color-fixing treatment:

[0058] 1.1. Prepare the color-fixing treatment solution, prepare an aqueous solution containing 2.5g / L phytic acid and 9.0g / L penetrant JFC, and adjust the pH to 5-7 with a 10g / L sodium hydroxide solution (for example, about 6.8), the color-fixing treatment solution is heated to 85°C and kept warm.

[0059] 1.2. After the natural colored silk strands are reeled (i.e. colored silk bobbins), soak them in the color-fixing treatment solution at a bath ratio of 1:30 (kg / L), take them out after the natural colored silk strands are completely wetted, and control the liquid The rate is 35%, and the colored silk bo...

Abstract

The invention discloses a green and environment-friendly processing method for high-quality natural colored silk fabrics, which includes fabric weaving processing, post-treatment including refined gray silk; before fabric weaving processing, glue-fixing treatment is carried out; the glue-fixing treatment is : the natural colored silk strands are subjected to glue-fixing treatment with a color-fixing treatment solution; the preparation method of the color-fixation treatment solution is: firstly prepare a mixed solution, and the mixed solution is composed of phytic acid with a concentration of 0.2 to 300 g / L , penetrant JFC with a concentration of 1-10g / L and water as the balance; adjust the pH of the mixed solution to 3.0-9.0 to obtain a color-fixing treatment solution; the color-fixing treatment temperature is 10-90°C. The method has the advantages of simple glue fixing process, environmental protection, and low economic cost; while maintaining bright colors, it also obtains better hand feeling.

Description

technical field [0001] The invention relates to the field of silk processing and product development thereof, in particular to a method for green and environment-friendly processing of high-quality natural colored silk products. Background technique [0002] Natural colored silk has color when the silkworm spins the silk. Its color comes from the natural pigment absorbed by the silkworm body into the mulberry leaves. It is non-toxic, harmless and colorful. It is a kind of silk raw material with natural color. Compared with silk products that have been dyed and printed with synthetic dyes, natural colored silk fabrics are environmentally friendly and do not require dyeing, which meets the consumption needs of modern people advocating nature. Significant health, environmental protection and economic advantages. [0003] However, most of the pigments of natural colored silk exist freely in the sericin of silk fibers. The pigments will be lost during the wet processing and dail...
