Description

Technical Field

[0001] The present invention belongs to the technical field of clothing finishing agents, and particularly relates to a clothing wrinkle-removing spray and a preparation method thereof. Background Art

[0002] Natural fibers, such as cotton fibers, have a relatively soft fiber structure and good moisture absorption. This softness makes cotton fabrics prone to deformation under the influence of external forces during wearing. In addition, compared with synthetic fibers (such as polyester), cotton fibers have poor elasticity, which means that it is difficult for cotton fabrics to return to their original shape after being stretched or squeezed by external forces, thus leaving wrinkles. In addition, fabric structures such as the interweaving, density, and thickness of warp and weft yarns will all affect the degree of wrinkling.

[0003] For the wrinkle-removing treatment of natural fibers, such as cotton fabrics, the commonly used methods currently include ironing to remove wrinkles, spraying water, or treating with a wrinkle-removing finishing agent. Among them, the wrinkle-removing finishing agent makes the wrinkles of the fabric easier to be smoothed by relaxing the fibers. The treated fabric is less likely to produce wrinkles during wearing and washing.

[0004] Currently, most of the wrinkle-removing finishing agents use resin materials as the main component. The resin material can effectively reduce the friction between fibers to reduce the generation of wrinkles by forming a uniform protective film on the fiber surface. The wrinkle-removing effect is good, but using resin materials as the main component will make the hand feeling of the finished fabric hard, the drapability decrease, and have a greater impact on the air permeability of the fabric, thereby causing a decrease in wearing comfort and affecting the serviceability of the fabric. Summary of the Invention

[0005] The purpose of the present invention is to provide a clothing wrinkle-removing spray and a preparation method thereof to solve the above problems.

[0006] The present invention achieves the above purpose through the following technical solutions:

[0008] As a further optimized scheme of the present invention, the rice bran protein copolymer emulsion, by mass, includes 100 parts of deionized water, 5 - 10 parts of rice bran protein, 0.05 - 0.2 parts of sodium sulfite, 5 - 10 parts of butyl acrylate, 0.2 - 0.4 parts of acrylic acid, 0.4 - 0.8 parts of sodium dodecyl sulfonate, 0.05 - 0.1 parts of ammonium persulfate, and 3 - 5 parts of ammonia water solution.

[0009] As a further optimized solution of the present invention, the preparation method of the rice bran protein copolymer emulsion is as follows: Add rice bran protein and sodium sulfite to deionized water and stir mechanically, add ammonia water solution to adjust the pH to 8, and stir at 60 °C for 2 h. Then add sodium dodecyl sulfonate, and at the same time add ammonium persulfate, acrylic acid and butyl acrylate to the reaction system at a dropping rate of 2 mL / h. After the dropping is completed, stir for 1 h and heat up to 90 °C, and continue to stir for 1 h to obtain the rice bran protein copolymer emulsion.

[0010] As a further optimized solution of the present invention, 2-6 parts by mass of deodorant nano-microcapsules are further added to the clothing wrinkle spray.

[0011] As a further optimized solution of the present invention, the deodorant nano-microcapsules are prepared by an ion gel method using chitosan as the wall material and deodorant aromatic essential oil as the core material.

[0012] As a further optimized solution of the present invention, the preparation method of the deodorant nano-microcapsules is as follows: First, dissolve chitosan in acetic acid solution to obtain a chitosan-acetic acid mixed solution, adjust the pH value of the chitosan-acetic acid mixed solution to 5.5, add Tween-80, and stir for 30 min under heating conditions to obtain a mixture. Then, add the deodorant aromatic essential oil to the mixture and stir evenly at room temperature to obtain an oil-in-water emulsion. Then, dropwise add sodium tripolyphosphate (TPP) to the oil-in-water emulsion, stir for 30 min, and then obtain nanoparticles by freeze centrifugation. Finally, wash the nanoparticles with ultrapure water, oscillate, and vacuum freeze-dry to obtain the deodorant nano-microcapsules.

[0013] As a further optimized solution of the present invention, the deodorant aromatic essential oil includes limonene and lemon essential oil with a mass ratio of 0.5-1:1.

[0014] As the second aspect of the present invention, there is also provided a preparation method of the clothing wrinkle spray as described in any one of the above, including the following steps:

[0015] (1) Heat the formulated amount of rice bran protein copolymer emulsion, sophorolipid, epichlorohydrin and ethanol to 50-60 °C, stir for 1-1.5 h, then add the remaining components of the formulated amount, stir for 30-50 min, cool down to 40-50 °C, and keep warm for 10-20 min;

[0016] (2) Under the pressure condition of 20-25 MPa, homogenize the mixed solution obtained in step (1) for 5-10 min, and then defoam and stand the homogenized mixed solution to obtain the clothing wrinkle spray.

[0017] The beneficial effects of the present invention are as follows:

[0018] The components of the clothing anti-wrinkle spray provided by the present invention include rice bran protein copolymer emulsion, sophorolipid, nano calcium carbonate, deodorant nano microcapsules, potassium dihydrogen phosphate, epichlorohydrin, magnesium sulfate, ethanol and distilled water. The anti-wrinkle property of the fabric is improved by forming a protective film on the fiber surface with the rice bran protein copolymer emulsion. The use of the surfactant sophorolipid can ensure the softness of the fabric while improving its anti-wrinkle property. The use of nano calcium carbonate and deodorant nano microcapsules can reduce the negative impact of the anti-wrinkle spray on the air permeability of the cotton fabric sample, ensuring the air permeability and softness of the fabric before and after using the anti-wrinkle spray, and making the fabric comfortable to wear.

[0032] The preparation method of the clothes wrinkle-removing spray is the same as that of Example 1.

[0033] Example 4

[0034] The clothing wrinkle-removing spray of this embodiment is composed of the following components in parts by mass: 27 parts of rice bran protein copolymer emulsion, 8 parts of sophorolipid, 2.5 parts of nano calcium carbonate, 3 parts of potassium dihydrogen phosphate, 2 parts of epichlorohydrin, 1 part of magnesium sulfate, 15 parts of ethanol, and 50 parts of distilled water.

[0036] The preparation method of the clothing wrinkle-removing spray is the same as that of Example 2.

[0037] Example 5

[0038] On the basis of the component formula of the clothing wrinkle-removing spray disclosed in Example 1, this embodiment additionally adds 6 parts by mass of deodorant nano microcapsules, and correspondingly reduces the distilled water to 54 parts by mass of distilled water.

[0039] The deodorant nano microcapsules are prepared by the ion gel method using chitosan as the wall material and deodorant aromatic essential oil as the core material. Specifically, first dissolve 0.6 g of chitosan with a mass concentration of 10 g / L in 40 mL of acetic acid solution with a volume percentage concentration of 1%, to obtain a chitosan-acetic acid mixed solution. Adjust the pH value of the chitosan-acetic acid mixed solution to 5.5, add 0.3 g of Tween-80, and stir at 50 °C for 30 min to obtain a mixture. Then, add 0.05 g of deodorant aromatic essential oil (limonene and lemon essential oil with a mass ratio of 1:1) to the mixture, stir evenly at room temperature to obtain an oil-in-water emulsion. Then, dropwise add 20 mL of the prepared 1.5 g / L TPP solution to the oil-in-water emulsion, stir for 30 min, and then obtain nanoparticles by freeze centrifugation. Finally, the nanoparticles are washed 2 times with ultrapure water, oscillated for 5 s, and vacuum freeze-dried at -50 °C for 24 h to obtain the deodorant nano microcapsules.

[0040] The clothing wrinkle-removing sprays prepared in Examples 1-5 are applied to the treatment of cotton fabrics. The usage method is the conventional usage method, that is, hanging the cotton fabric specimen in a ventilated place, keeping the distance between the spray and the clothes between 10-20 cm, and evenly spraying the spray onto the surface of the cotton fabric specimen. Ensure that the spraying amount of each treatment group is equivalent, and set 5 parallel samples for each treatment group.

[0041] The following items were tested for each treatment group:

[0042] (1) Crease recovery angle test: GB / T 3819-1997 "Textiles - Determination of crease recovery of fabrics - Recovery angle method". The cotton fabric specimen was folded and pressed under specified conditions, and the crease recovery angle was measured after unloading. The crease recovery angle read 5 minutes after unloading the load from the cotton fabric specimen was taken as the test result.

[0043] (2) Drapeability test: Using a YG 811 fabric drape meter, the umbrella method was adopted and tested according to the FZ / T 01045-1996 standard. The drape coefficient F = (S3 - S2) / (S1 - S2), where S1 is the area of the cotton fabric specimen, S2 is the area of the clamping disc, and S3 is the projected area of the cotton fabric specimen.

[0044] (3) Air permeability test: Referring to the national standard (GB / T5433), a YG461G fully automatic fabric air permeability meter was used to test the air permeability of the samples. Among them, the specific experimental parameters were set as follows: the ambient temperature was 25°C, the relative humidity was 60%, the pressure difference was 100 Pa, the air permeable area was 20 cm 2 , and the diameter of the air jet nozzle was 0.8 mm. The fabric samples were tested 10 times at different positions respectively, and the average value was taken as the final air permeability data.

[0045] The fabric specimens for the above test items were commercially available cotton fabrics. The crease recovery angle of the cotton fabric in the dry state was 182, the drape coefficient was 45%, and the air permeability was 296 mm / s.

[0046] The results are shown in Table 1.

[0047] Table 1. Result statistical table

[0048]

[0049]

[0050] It can be seen from the table that compared with the original cotton fabric, after being treated with the clothing wrinkle removal spray of the example, the crease recovery angle (dry state) of the cotton fabric specimen increased from the original 182 to between 224 - 285, indicating that the elasticity of the cotton fabric specimen increased and the wrinkle resistance of the cotton fabric specimen improved. In addition, the drape coefficient of the cotton fabric specimen decreased from the original 45% to 28 - 40%, indicating that the softness of the cotton fabric was improved to a certain extent. Finally, after being treated with the clothing wrinkle removal spray of the example, the air permeability of the cotton fabric specimen decreased to a certain extent, but the overall change was not significant.

[0051] To explore the influence of the composition of the clothing wrinkle removal spray on its performance, the following comparative examples were set as shown in Table 2.

[0052] Table 2. Summary of Comparative Example Settings

[0053]

[0054] The clothing wrinkle-removing sprays prepared in Comparative Examples 1-5 were also tested for the three items of wrinkle recovery angle, drapability and air permeability. The results are shown in Table 3.

[0055] Table 3. Result Statistical Table

[0056]

[0057] It can be seen from Table 3 that by comparing Example 1 with Comparative Example 1, both the rice bran protein copolymer emulsion and the aqueous polyurethane emulsion can improve the wrinkle resistance of the cotton fabric specimen. However, the film formation of the aqueous polyurethane emulsion will cause the hand feeling of the cotton fabric specimen to become hard, affecting its softness. Its drape coefficient increases compared with the original cotton fabric specimen. In addition, the air permeability of the cotton fabric specimen also decreases to a large extent compared with the original cotton fabric specimen.

[0058] By comparing Example 1 with Comparative Example 2, it can be seen that the degree of influence of the wrinkle-removing spray added with nano calcium carbonate on the air permeability of the cotton fabric specimen is lower than that of the wrinkle-removing spray without nano calcium carbonate.

[0059] By comparing Example 1 with Comparative Example 3, sophorolipid and polyvinylpyrrolidone both belong to surfactants and can improve the wrinkle resistance of the cotton fabric specimen. However, the effect of sophorolipid in improving the softness of the cotton fabric specimen is better than that of polyvinylpyrrolidone.

[0060] By comparing Example 1 with Comparative Example 4, the degree of influence of the wrinkle-removing spray added with deodorant nano microcapsules on the air permeability of the cotton fabric specimen is lower than that of the wrinkle-removing spray without deodorant nano microcapsules. Compared with Comparative Example 4, in Comparative Example 5, limonene and lemon essential oil were added to the wrinkle-removing spray in a non-microcapsule form, and there is no obvious positive effect on improving the influence of the wrinkle-removing spray on the air permeability of the cotton fabric specimen.

[0061] The above-described embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
