Embodiment 1

[0020] A pretreatment process for silk dyeing, comprising the following steps:

[0021] Step 1, immerse the silk in an ammonia solution with a mass fraction of 5%, heat it to 40°C, and keep it for 40 minutes;

[0022] Step 2, immerse the silk treated in step 1 in 20% ethanol solution, heat and boil, and keep for 10 minutes;

[0023] Step 3, immersing the silk treated in step 2 into a calcium chloride solution with a mass fraction of 5%, heating to 70° C., and stirring for 20 minutes, wherein the stirring speed is 100 rpm, and the temperature is lowered to room temperature;

[0024] Step 4, immerse the silk treated in Step 3 in 0.1mol / L phosphoric acid solution, keep the temperature at 30°C, and stir for 10 minutes at a stirring speed of 70 rpm;

[0025] In step five, the silk treated in step four is washed with deionized water at a temperature of 40° C., and then dyeing can be carried out.

Embodiment 2

[0027] A pretreatment process for silk dyeing, comprising the following steps:

[0028] Step 1, immerse the silk in an ammonia solution with a mass fraction of 6%, heat it to 43°C, and keep it for 45 minutes;

[0029] Step 2, immerse the silk treated in step 1 in 25% ethanol solution, heat and boil for 12 minutes;

[0030] Step 3, immersing the silk treated in step 2 into a calcium chloride solution with a mass fraction of 6%, heating to 73°C, and stirring for 28 minutes, wherein the stirring speed is 105 rpm, and the temperature is lowered to room temperature;

[0031] Step 4, immerse the silk treated in Step 3 in 0.1mol / L phosphoric acid solution, keep the temperature at 33°C, and stir for 15 minutes at a stirring speed of 74 rpm;

[0032] In step five, the silk treated in step four is cleaned with deionized water at a temperature of 45° C., and then dyeing can be performed.

Embodiment 3

[0034] A pretreatment process for silk dyeing, comprising the following steps:

[0035] Step 1, immerse the silk in an ammonia solution with a mass fraction of 6%, heat it to 47°C, and keep it for 50 minutes;

[0036] Step 2, immerse the silk treated in step 1 in 25% ethanol solution, heat and boil for 16 minutes;

[0037] Step 3, immersing the silk treated in step 2 into a calcium chloride solution with a mass fraction of 8%, heating to 76°C, and stirring for 32 minutes, wherein the stirring speed is 110 rpm, and the temperature is lowered to room temperature;

[0038] Step 4, immerse the silk treated in Step 3 in 0.1mol / L phosphoric acid solution, keep the temperature at 38°C, and stir for 16 minutes at a stirring speed of 78 rpm;

[0039] In step five, the silk treated in step four is cleaned with deionized water at a temperature of 46° C., and then dyeing can be performed.

Abstract

The invention discloses a pretreatment process for silk dyeing. According to the pretreatment process for silk dyeing, silk is soaked in an ammonia-water solution to be heated to 40-50 DEG C, and then the solution stays for 40-60 min; the processed silk is soaked in a 20-30% ethanol solution to be heated to boiling, the solution stays for 10-20 min, then the silk is soaked in a calcium chloride solution to be heated to 70-80 DEG C and stirred for 20-40 min, and then temperature is reduced to indoor temperature; the processed silk is soaked in a 0.1 mol / L phosphoric acid solution, temperature is maintained to be 30-40 DEG C, and stirring is conducted for 10-20 min; finally, the processed silk is cleaned through phosphoric acid so that dyeing can be conducted. By the adoption of the pretreatment process for silk dyeing, the processed silk can be dyed quickly, color revivification degree is high, testing shows that light fastness can reach over six grade, crockfastness can reach over four grade and color fastness to washing reaches four grade, and therefore dyeing can be well achieved.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a silk dyeing pretreatment process. Background technique [0002] According to archaeological discoveries, China has utilized silk to make silk thread, weave silkworm cocoons, silk ribbons and simple silk fabrics about 4,700 years ago. During the Shang and Zhou dynasties, silk was used to weave silk products such as Luo, damask, Wan, yarn, crepe, Qi, brocade and embroidery. Silkworms include mulberry silkworm, tussah silkworm, castor silkworm, cassava silkworm, willow silkworm and celestial silkworm. The thread drawn from a single silkworm cocoon is called cocoon silk. It is made of two single fibers bonded by sericin. When reeling, the cocoons of several silkworm cocoons are pulled out and glued into silk strips by sericin, collectively called silk. Silk without sericin is called refined silk. Mulberry silk is the most used silk, followed by tussah...
