Description

Technical Field

[0001] This invention belongs to the field of fabric dyeing technology, specifically relating to a color difference treatment agent for down fabrics and its preparation method. Background Technology

[0002] Down fabric is a material used to make clothing. During the production and processing of down fabric, it needs to be dyed to meet the needs of different consumer groups. Because dyeing is a very complex process, it requires high precision in terms of air temperature, humidity, and dyeing time. When dyeing a batch of down fabric, a small number of pieces may have color differences from the desired color. To reduce color differences, the fabric is soaked in a color difference treatment agent before dyeing to increase the adhesion of the dye to the fabric, making it easier for subsequent dyeing and reducing color differences. Summary of the Invention

[0003] The purpose of this invention is to provide a color difference treatment agent for down fabrics and its preparation method in order to solve the above-mentioned problems.

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] This invention provides a method for preparing a color difference treatment agent for down fabrics, comprising the following steps:

[0006] Step S1: Mix potassium hydrogen tartrate, mannitol and activated carbon, then add distilled water and stir until fully dissolved to obtain solution A;

[0007] Step S2: Mix gum arabic powder, guar gum powder and black fungus gum powder, pulverize and pass through a 60-mesh sieve to obtain natural plant gum powder;

[0008] Step S3: Mix ethanol, acetone and hydrogen peroxide to obtain solution B;

[0009] Step S4: Heat and stir the natural plant gum powder obtained in S2 with solution B obtained in S3 to obtain a softener. Store the softener at a constant temperature of 60°C for later use.

[0010] Step S5: Mix solution A obtained in S1 with softener obtained in S4 to obtain color difference treatment agent.

[0011] As a further optimization of the present invention, in S1, the raw materials for preparing solution A, by weight, include: 20-35 parts of potassium hydrogen tartrate, 5-10 parts of mannitol, 10-20 parts of activated carbon, and 60-80 parts of distilled water.

[0012] As a further optimization of the present invention, in step S2, the raw materials for preparing natural plant gum powder include, by weight, 20-35 parts of gum arabic powder, 45-60 parts of guar gum powder, and 25-46 parts of black fungus gum powder.

[0013] As a further optimization of the present invention, in step S3, the raw materials for preparing solution B, by weight, include: 2-7 parts of ethanol, 10-15 parts of acetone, and 8-16 parts of hydrogen peroxide.

[0014] As a further optimization of the present invention, in step S4, the mass ratio of natural plant gum powder to solution B is 1:1.5.

[0015] As a further optimization of the present invention, in step S5, the mass ratio of solution A to softener is 1:2.

[0016] As a further optimization of the present invention, in step S1, the stirring speed is 25 rpm and the stirring time is 30 min.

[0017] As a further optimization of the present invention, in step S4, the stirring speed is 60 rpm and the heating temperature is 40-50℃.

[0018] A color difference treatment agent for down fabrics as described above, which is prepared by the above production method.

[0019] The beneficial effects of this invention are as follows: By adding activated carbon, potassium bitartrate, and mannitol to solution A, the three components work synergistically to increase the color fastness to washing, dry cleaning, and rubbing of the down fabric sample, reducing the possibility of color difference during dyeing. Combining solution A with a softener reduces the shrinkage problem of down fabrics during washing. Furthermore, the addition of natural plant gum powder to the softener, along with solution B, allows the natural plant gum powder to easily adhere to the down fabric under the action of solution B, further increasing the tensile strength of the fabric and extending its service life.

[0030] II. Methods

[0031] 2.1 Effect of Solution A on the Performance of Color Difference Treatment Agent

[0032] (1) The preparation method of the color difference treatment agent is as follows:

[0033] Potassium hydrogen tartrate, mannitol and activated carbon were mixed, and then distilled water was added and stirred until fully dissolved (stirring speed was 25 rpm and stirring time was 30 min) to obtain solution A;

[0034] Mix gum arabic powder, guar gum powder and black fungus gum powder, and pulverize them through a 60-mesh sieve to obtain natural plant gum powder;

[0035] Ethanol, acetone and hydrogen peroxide are mixed to obtain solution B;

[0036] Natural plant gum powder and solution B are heated and stirred at a mass ratio of 1:1.5 (stirring speed 60 rpm, heating temperature 40-50℃) to obtain a softener. The softener is stored at a constant temperature of 60℃ for later use.

[0037] Solution A and softener are mixed at a mass ratio of 1:2 to obtain a color difference treatment agent.

[0038] The raw material composition of the natural plant gum powder includes 28 parts of gum arabic powder, 50 parts of guar gum powder, and 34 parts of black fungus gum powder.

[0039] The raw material composition of solution B includes 5 parts ethanol, 12 parts acetone and 13 parts hydrogen peroxide;

[0040] The raw material composition of solution A is shown in the table below:

[0041]

[0042] Note: "-" indicates no addition.

[0043] The down fabric samples used were made of a blend of 30% natural cotton fiber, 50% polyester fiber and 20% silk fiber, with the down fabric sample without soaking in color difference treatment agent serving as comparative example A.

[0044] (2) The performance of down fabric samples soaked in the above color difference treatment agent was tested using the following test methods.

[0045] ①According to GB / T 12490-1990 "Test Methods for Color Fastness to Domestic and Commercial Washing of Textiles", the down fabric samples soaked in color difference treatment agent in Examples 1-2, and the down fabric samples soaked in color difference treatment agent in Comparative Example A and Comparative Example 1-3 were tested for their color fastness to washing.

[0046] ② In accordance with GB / T 5711-2015 "Textiles - Tests for color fastness to tetrachloroethylene - Dry cleaning fastness", the down fabric samples soaked in the color difference treatment agent of Examples 1-2, and the down fabric samples soaked in the color difference treatment agent of Comparative Example A and Comparative Example 1-3 were tested for dry cleaning fastness.

[0047] ③ In accordance with GB / T 3920-2008 "Textiles - Tests for color fastness to rubbing", the down fabric samples soaked in the color difference treatment agent of Examples 1-2, and the down fabric samples soaked in the color difference treatment agent of Comparative Example A and Comparative Example 1-3 were tested for their color fastness to rubbing.

[0048] The results are shown in the table below:

[0049]

[0050] As can be seen from the table above, the values ​​obtained from the color fastness tests (washing fastness, dry cleaning fastness, and rubbing fastness) indicate that the down fabric samples soaked in the color difference treatment agent prepared in Examples 1-2 exhibit superior performance in these three aspects compared to the down fabric samples soaked in the color difference treatment agent prepared in Comparative Examples A and 1-3, meeting the acceptable standards. Furthermore, the table shows that the down fabric sample in Example 2 met the acceptable standards in all three color fastness tests (washing fastness, dry cleaning fastness, and rubbing fastness). A comparison of the data from Example 2 and Comparative Example 1 reveals that the use of activated carbon... The addition of activated carbon will increase the dry cleaning color fastness of the down fabric samples. Comparative Example 2 shows that after adding an equal amount of activated carbon, the dry cleaning color fastness is the same as in Example 2. However, after reducing the amount of distilled water and removing potassium bitartrate, the water washing color fastness of Comparative Example 2 is significantly lower than that of Example 2. Comparative Example 3 shows that reducing the amount of mannitol significantly decreases the rubbing color fastness of the down fabric samples. Furthermore, based on the data from Example 2, Comparative Example A, and Comparative Examples 1-3, it is evident that activated carbon, potassium bitartrate, and mannitol work synergistically to increase the water washing color fastness, dry cleaning color fastness, and rubbing color fastness of the down fabric samples.

[0051] 2.2 The Influence of Natural Plant Gum Powder on the Performance of Color Difference Treatment Agents

[0052] (1) The preparation method of the color difference treatment agent is described in 2.1-(1), wherein the natural plant gum powder described in the table below is used to replace the natural plant gum powder in Example 2.

[0053] The raw material composition of natural plant gum powder is shown in the table below:

[0054]

[0055] Note: "-" indicates no addition.

[0056] (2) The performance of down fabric samples soaked in the above color difference treatment agent was tested using the following test methods.

[0057] ① For the test of color fastness to washing, refer to 2.1-(2)-①.

[0058] ② For dry cleaning color fastness performance testing, refer to 2.1-(2)-②.

[0059] ③The test of color fastness to rubbing is based on 2.1-(2)-③.

[0060] ④ The tensile properties of the down fabric samples soaked in the color difference treatment agent in Example 3 and Comparative Examples 4-7 were tested according to GB / T3923.2-2013 "Textiles - Tensile properties of fabrics - Part 2: Determination of breaking strength - Sampling method".

[0061] The results are shown in the table below:

[0062]

[0063] As can be seen from the table above, the down fabric sample soaked in the color difference treatment agent prepared in Example 3 exhibits superior tensile strength. Comparing the data of Example 3 and Comparative Example 4, it can be concluded that the data obtained from the amount used in Example 3 is superior. Comparing Comparative Examples 4-7, Comparative Example 4 is the best among the four comparative examples, but the data is still not ideal after comparison with Comparative Example 3. Therefore, it is concluded that the amount used in Example 3 is optimal, and the prepared color difference treatment agent can enable the down fabric sample to achieve good tensile strength. This means that Example 3 not only has good wash fastness, dry cleaning fastness, and rubbing fastness, but also good tensile strength.

[0064] 2.3 Effect of Solution B on the Performance of Color Difference Treatment Agent

[0065] (1) The preparation method of the color difference treatment agent is the same as 2.1-(1), except that the solution B in Example 3 is replaced by the solution B described in the table below.

[0066] The raw material composition of solution B is shown in the table below:

[0067]

[0068] Note: "-" indicates no addition.

[0069] (2) The performance of down fabric samples soaked in the above-mentioned color difference treatment agent was tested using the following test methods.

[0070] ① For the test of color fastness to washing, refer to 2.1-(2)-①.

[0071] ② For dry cleaning color fastness performance testing, refer to 2.1-(2)-②.

[0072] ③The test of color fastness to rubbing is based on 2.1-(2)-③.

[0073] ④ In accordance with GB / T 8629-2017 "Textiles - Household washing and drying procedures for testing", the down fabric samples soaked in the color difference treatment agents of Examples 4 and 7-10 were subjected to washing shrinkage tests.

[0074] The results are shown in the table below:

[0075]

[0076]

[0077] As can be seen from the table above, Example 4 is superior to Comparative Examples 9-10 in terms of color fastness to washing. Although Comparative Example 8 has better color fastness to dry cleaning, the data shows that its color fastness to washing and color fastness to rubbing are far inferior to Examples 3-4. Comparative Example 9 is inferior to Example 4 in terms of color fastness to dry cleaning, color fastness to washing, and color fastness to rubbing. Comparative Example 10 is inferior to Example 4 in terms of color fastness to washing and color fastness to rubbing. Based on the above data, it can be seen that the synergistic effect of acetone, hydrogen peroxide, and ethanol added in Example 4 can reduce the shrinkage of down fabrics during washing.

[0078] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
