Problems solved by technology

[0002]Natural yellow silk fabrics must be degummed before use, but in the traditional yellow silk degumming process, due to the influence of degumming reagents, temperature, concentration and other factors, it is easy to produce Problems such as uneven degumming and large color loss seriously affect the natural color of colored silk fabrics, thereby affecting the quality of cocoon silk and failing to meet environmental protection requirements

Embodiment 1

[0014] Use the Digieye color measuring instrument to select the CIELAB color space, measure the color of the yellow silk fabric, and measure the color value L of the fabric before degumming * (brightness) = 85.50, a * (Green / Red)=5.87, b * (blue / yellow)=42.06; Sodium bicarbonate (NaHCO 3 ) into a solution with a concentration of 4g / L; then the natural yellow silk fabric such as figure 1 Place it in the above-prepared solution with a bath ratio of 1:100; raise the temperature to 82°C, and degumming for 70 minutes. Then use the Digieye color meter to select the CIELAB color space, measure the color of the yellow silk fabric after degumming, and measure the color value L of the degummed fabric * (Brightness) = 73.76, a * (Green / Red)=3.94, b * (blue / yellow) = 31.55, the color difference calculated by using the CIEDE2000 color difference formula is 9.09, and the sericin dissolution rate of natural yellow silk fabric is 22.7%. The total sericin content of the fabric is 28.8%,...

Embodiment 2

[0019] Use the Digieye color measuring instrument to select the CIELAB color space, measure the color of the yellow silk fabric, and measure the color value L of the fabric before degumming * (brightness) = 85.50, a * (Green / Red)=5.87, b * (blue / yellow)=42.06; neutral soap was prepared into a solution with a concentration of 5g / L; then natural yellow silk fabrics such as figure 1 Put it in the solution prepared above, the bath ratio is 1:100; heat up to 80°C, degumming for 50min. Then use the Digieye color meter to select the CIELAB color space, measure the color of the yellow silk fabric after degumming, and measure the color value L of the degummed fabric * (brightness)=73.50, a * (Green / Red)=4.20, b * (blue / yellow) = 32.00, the color difference calculated by using the CIEDE2000 color difference formula is 9.18, and the sericin dissolution rate of natural yellow silk fabric is 23.2%.

Embodiment 3

[0023] Use the Digieye color measuring instrument to select the CIELAB color space, measure the color of the yellow silk fabric, and measure the color value L of the fabric before degumming * (brightness) = 85.50, a * (Green / Red)=5.87, b * (blue / yellow) = 42.06; Sodium carbonate was formulated into a solution with a concentration of 6g / L; then natural yellow silk fabrics such as figure 1 Place it in the solution prepared above with a bath ratio of 1:100; raise the temperature to 85°C and degumming for 30 minutes. Then use the Digieye color meter to select the CIELAB color space, measure the color of the yellow silk fabric after degumming, and measure the color value L of the degummed fabric * (brightness)=74.20, a * (Green / Red)=3.90, b * (blue / yellow)=30.50, the color difference calculated by CIEDE2000 color difference formula is 9.02, and the sericin dissolution rate of natural yellow silk fabric is 22.0%

Abstract

The invention discloses a degumming process of natural yellow silk fabrics. The degumming process comprises the following steps: 1) preparing a degumming reagent into a solution of which the concentration is 4-6g / L; 2) placing a natural yellow silk fabric into the solution prepared in the step 1), wherein the bath ratio is 1:100, heating to 80-85 DEG C, and degumming for 30-70 minutes. The degumming process is suitable for a degumming process of the natural yellow silk fabric; with the adoption of the degumming process, proper silk gum dissolve-loss ratio is obtained through controlling the factors such as the degumming time, the degumming temperature and the degumming reagent and the like, colors are retained to a large extent, and the problems that degumming is not uniform and colors are not uniform in the traditional degumming process are overcomesolved, so that not only is the gum-containing rate of the fabric is ensured, but also the natural color value of the fabric is retained to a large extent; and the degumming process of the natural yellow silk fabrics has the advantages of good degumming effect and, environmental protection friendliness,and short time and the like, and can be used for natural yellow silk fabrics of various tissues.

Description

technical field [0001] The invention relates to a degumming process of silk fabrics, in particular to a degumming process of natural yellow silk fabrics. Background technique [0002] Natural yellow silk fabrics must be degummed before use, but in the traditional yellow silk degumming process, due to the influence of degumming reagents, temperature, concentration and other factors, it is easy to produce problems such as uneven degumming and large color loss, which seriously affect the quality of colored silk. The natural color of the fabric will affect the quality of cocoon silk and fail to meet environmental protection requirements. This just needs a kind of degumming process for natural yellow silk fabric, makes the yellow silk fabric after degumming not only have appropriate sericin dissolution rate, but also retain its natural color difference to the greatest extent. content of the invention [0003] The object of the present invention is to provide a degumming p...
