The beneficial effects of the invention are as follows: according to the soft water treatment process for the silk floss of the mulberry silkworms, soft water with less calcium and magnesium ions is used in the silk floss boiling and subsequent soft treatment processes, so that calcium and magnesium ions and carbonate or other anions in the used auxiliary agent can be prevented from forming precipitates, the boiling effect of the silk floss is influenced, the prepared silk floss has softer hand feeling and brighter and cleaner luster, and the silk floss treatment effect is improved.
Detailed Description
The invention will be further illustrated with reference to specific examples.
Examples
The mulberry silk floss soft water treatment process related to the embodiment comprises the following steps: s1, stripping cocoons, S2, boiling silk floss, S3, cleaning, and drying by soft S4.
In the step S1, silk floss is peeled after the silk cocoons are soaked in 60-80 ℃ alkaline solution and softened. Specifically, in this example, the temperature of the alkaline solution was 70 ℃. The alkaline solution contains 3-5% of sodium hydroxide. Specifically, in this example, the alkaline solution contained 4% sodium hydroxide. In this step, the weight ratio of soft water to cocoons is 100:1.
in the step S2 of boiling silk floss, the silk floss peeled in the previous step is placed in soft water and boiled for 2 to 3 hours at the temperature of 95 to 100 ℃; sodium silicate, sodium carbonate, an oil remover and hydrogen peroxide are added into the soft water. In this step, the weight ratio of soft water to silk floss is 100:4. after the addition of the above-mentioned auxiliary agents, the pH value of the soft water was 13. The used deoiling agent is environment-friendly.
Further, in this step, 3 to 5 parts by mass of sodium silicate, 3 to 5 parts by mass of sodium carbonate, 1 to 2 parts by mass of an oil remover and 2 to 4 parts by mass of hydrogen peroxide are contained per 100 parts by mass of soft water. Specifically, in this example, 5 parts by mass of sodium silicate, 5 parts by mass of sodium carbonate, 2 parts by mass of an oil remover and 4 parts by mass of hydrogen peroxide were contained per 100 parts by mass of soft water.
The water quality selected has a certain influence on the refining and boiling effects of silk floss. If the selected water belongs to hard water, the hard water contains more calcium and magnesium ions, and when the silk floss of mulberry silkworms is treated, the hard water can be combined with carbonate ions and silicate ions to form precipitates and adhere to the surface of silk, so that the boiling effect of the silk floss of mulberry silkworms is influenced, and particularly, the hand feeling and luster of the silk floss are influenced.
The soft water referred to in this example means water having a hardness of less than 60mg/L, and may specifically be 30mg/L.
And in the step S3 of cleaning and softening, the silk floss obtained in the previous step is placed in soft water at normal temperature for cleaning, and after spin-drying, the silk floss is placed in soft water containing food-grade citric acid and softening agent for soaking for 0.5-1h. In this step, the weight ratio of soft water to silk floss is 100:4.
further, the content of the citric acid in the soft water is 1-3%, and the content of the softener in the soft water is 3-5%. In particular, in this example, the content of citric acid in soft water was 2%, and the content of softener in soft water was 4%.
In the step S4 of drying, the silk floss prepared in the previous step is dried by a dryer, and then the silk floss is dried in a drying room. Specifically, the temperature in the drying room is 90 ℃.
If hard water is used in the refining and boiling process, more calcium and magnesium ions are contained in the hard water, and the calcium and magnesium ions react with carbonate ions and silicate ions to generate precipitates which are adhered to the surface of silk during the refining and boiling process, so that the refining and boiling effect of silk is affected. As soft water is used, the soft water contains less calcium and magnesium ions, and has less influence on the boiling effect of mulberry silk, the treated silk floss has softer hand feeling and better glossiness.
Comparative example
A silk floss treatment process of mulberry silkworms according to the comparative example is different from the examples in that the water used is conventional tap water. The hardness of tap water is about 8, and the content of calcium and magnesium ions is 120-180 mg/L.
The silk floss prepared in examples and comparative examples was subjected to absolute dimensional evaluation. The absolute scale evaluation is to make experimenters observe test objects one by one, and rank the two silk floss of the examples and the comparative examples from high to low in hand feeling and luster by subjective judgment of the testers.
The method comprises the following specific steps: ambient temperature 25 ℃, bright room; 10 colorless, blind and weak employees, with a male-female ratio of 1:1, a step of; the silk floss treated by the examples and the comparative examples is placed on a table; the softness and color were ordered by 10 testers in sequence. 10 test persons showed that the silk floss prepared in the examples was superior to the silk floss prepared in the comparative examples in terms of softness and color.
The silk floss prepared by the method has a certain moisture absorption performance and a good antistatic performance, so that dust in the air can be prevented from being adsorbed, and anaphylactic reaction caused by the dust can be effectively reduced in the use process of the silk floss. And the silk fiber has certain antibacterial and antibacterial effects, so that the prepared silk quilt can effectively inhibit anaphylactic reaction caused by mites in the use process. In conclusion, the silkworm silk floss prepared by the method has low sensitization to dust mites.
The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
