Description

Technical Field

[0001] This application relates to the field of clothing technology, and in particular to a dress made of velvet fabric with oblique seam stitching and its preparation method. Background Technology

[0002] Velvet fabric, also known as pile fabric, is a type of fabric with a velvety surface, such as velvet, corduroy, plush, and silk velvet. The pile direction can be either light or dark; the light-colored side is lighter and brighter, while the darker side is darker and absorbent. Velvet fabric has a strong velvety feel, and the pile has a lustrous sheen when stood upright. It has a unique silky rustle, a smooth hand feel, is comfortable to wear, and exudes elegance and luxury. Velvet dresses, in particular, are favored by many women.

[0003] Velvet fabric itself has certain antibacterial properties, but it is still easy to accumulate dirt and grime when exposed to the air for a long time, becoming a breeding ground for bacteria. Especially during the rainy season or in humid climates, bacteria will multiply rapidly, the fabric fibers will be corroded, and an odor will be emitted, which will harm the health of users. Therefore, it needs to be improved. Summary of the Invention

[0004] To improve the antibacterial properties of a dress, this application provides a dress made of velvet fabric with oblique seam stitching and a method for preparing the same.

[0005] The present application provides a velvet fabric diagonally stitched dress and its preparation method, which adopts the following technical solution: Firstly, the present application provides a velvet fabric diagonally stitched dress, which adopts the following technical solution:

[0006] A dress made of velvet fabric with diagonal seams, characterized in that: the dress is made of velvet fabric with diagonal seams, and the velvet fabric is obtained by treating the fabric body with an antibacterial finishing solution, the antibacterial finishing solution comprising the following components in parts by weight:

[0007] 10-20 parts modified chitosan

[0008] 10-15 parts of adhesion promoter

[0009] 5-10 parts of modified metal-organic framework material

[0010] 60-80 parts water.

[0011] Modified chitosan, through modification treatment, can improve the antibacterial properties and softness of fabrics; adhesion promoters can enhance the adhesion of each component in the antibacterial finishing solution to the fabric, improve the wash fastness of the fabric, and thus enhance the antibacterial properties of the fabric; modified metal-organic framework materials have good antibacterial properties and reactivity, and undergo cross-linking reactions with modified chitosan and adhesion promoters. The three work synergistically to improve the wash fastness and antibacterial properties of the fabric.

[0012] Preferably, the modified chitosan comprises thioctic acid-grafted chitosan and gemini quaternary ammonium salt.

[0013] Lipoic acid-grafted chitosan possesses excellent softness, antibacterial properties, and antioxidant properties. Fabrics treated with lipoic acid-grafted chitosan are softer and more comfortable, and have good wrinkle resistance. Gemini quaternary ammonium salts have a bis-quaternary ammonium salt structure, which has a better ability to kill bacteria than quaternary ammonium salts, thus improving the antibacterial properties of velvet fabrics. Gemini quaternary ammonium salts also have better positive charge, which can capture and quench free radicals, thus improving the antioxidant properties of velvet fabrics.

[0014] Preferably, the lipoic acid-grafted chitosan comprises chitosan matrix, 1-ethyl-(3-dimethylaminopropyl)carbodiimide, and α-lipoic acid.

[0015] 1-Ethyl-(3-dimethylaminopropyl)carbodiimide activates the carboxyl group of α-lipoic acid, making α-lipoic acid chitosan more susceptible to grafting reaction, thus yielding lipoic acid-grafted chitosan.

[0016] Preferably, the gemini quaternary ammonium salt is prepared using the following steps:

[0017] Triethylamine and 1,3-dibromo-1-propene were mixed and dispersed in anhydrous ethanol to obtain a reaction solution. The reaction was heated and then cooled to obtain a crude product. The crude product was distilled under reduced pressure. The crude product after reduced pressure distillation was washed, filtered, and dried to obtain the gemini quaternary ammonium salt.

[0018] Geminid quaternary ammonium salts prepared according to the above steps have good antibacterial and antioxidant properties.

[0019] Preferably, the mass ratio of the lipoic acid-grafted chitosan to the gemini quaternary ammonium salt is 1:(0.2-0.3).

[0020] Gemini quaternary ammonium salts prepared according to the above mass ratio exhibit good antibacterial and antioxidant properties.

[0021] Preferably, the adhesion promoter comprises tannic acid and graphitic carbon nitride.

[0022] Tannic acid possesses excellent antibacterial and antioxidant properties. It also exhibits a catechol structure similar to mussel protein, enabling it to adhere to the fabric surface and enhance the binding strength between the components in the antibacterial finishing solution and the velvet fabric, thereby improving the fabric's antibacterial and antioxidant properties. Graphite-phase carbon nitride also possesses antibacterial and antioxidant properties. Modifying graphite-phase carbon nitride with tannic acid can improve its dispersibility. The synergistic effect of tannic acid and graphite-phase carbon nitride further enhances the fabric's antibacterial and antioxidant properties.

[0023] Preferably, the mass ratio of tannic acid to graphitic carbon nitride is (0.4-0.5):1.

[0024] The adhesion promoter obtained according to the above mass ratio has good adhesion properties, antibacterial properties and antioxidant properties.

[0025] Preferably, the modified metal-organic framework material includes an ammonia-modified zinc-based metal-organic framework material and ferulic acid.

[0026] Ammonia-modified zinc-based metal-organic frameworks (MOFs) introduce amino structures, increasing the number of active groups on the surface of the MOF and enhancing its reactivity. This, in turn, improves the bonding strength between the modified MOF and other antibacterial components and the velvet fabric. Ammonia-modified MOFs exhibit excellent antibacterial and antioxidant properties, capable of quenching cellular bioactive substances and scavenging free radicals, thus enhancing the antioxidant and antibacterial properties of the velvet fabric. Ferulic acid possesses excellent free radical scavenging capabilities, exhibiting antibacterial and anti-inflammatory effects. By loading ferulic acid onto the surface of the ammonia-modified MOF, long-lasting and sustained-release antibacterial and antioxidant properties can be achieved, further enhancing the antibacterial and antioxidant properties of the velvet fabric.

[0027] Modified metal-organic framework materials and adhesion promoters can self-assemble into a cavity-like nanocage structure, providing long-lasting antibacterial and antioxidant properties. The composite of modified metal-organic framework materials and adhesion promoters adheres and fixes to the surface of velvet fabric, supporting the fibers in the velvet fabric, reducing slippage and deformation between fibers, and working synergistically with modified chitosan to improve the softness and wrinkle resistance of velvet fabric.

[0028] Preferably, the modified metal-organic framework material is prepared using the following steps:

[0029] Zinc nitrate hexahydrate was dispersed in N,N-dimethylformamide to obtain solution A. 2-aminobenzimidazole and benzimidazole were dispersed in methanol to obtain solution B. Solution A and solution B were mixed to obtain a mixture. The mixture was stirred and reacted. The mixture was centrifuged to obtain a precipitate. The precipitate was washed and dried to obtain an aminated zinc-based metal-organic framework material.

[0030] A modified solution was prepared by mixing and dispersing zinc-based aminated metal-organic framework material, ferulic acid, anhydrous ethanol and N,N-dimethylformamide. The modified solution was heated to react, and the reacted modified solution was centrifuged to obtain the product. The product was washed and dried to obtain the modified metal-organic framework material.

[0031] The modified metal-organic framework material prepared according to the above steps has good antibacterial and antioxidant properties.

[0032] Secondly, this application provides a method for preparing a dress with oblique seam stitching on velvet fabric, using the following technical solution:

[0033] A method for preparing a dress with oblique seam splicing on velvet fabric, characterized by the following steps: mixing and dispersing modified chitosan, adhesion promoter and modified metal-organic framework material in water, and then ultrasonically stirring to obtain an antibacterial finishing solution;

[0034] The fabric body is immersed in an antibacterial finishing solution, then dried and heated for a second drying process. The fabric body after the second drying is washed with water and then dried to obtain velvet fabric.

[0035] Cut multiple velvet pieces from the velvet fabric according to the style of the dress, and sew the velvet pieces together to obtain a dress with diagonal seams on the velvet fabric.

[0036] The velvet fabric diagonally stitched dress prepared according to the above steps has good antibacterial properties, antioxidant properties, and wrinkle-resistant properties.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. Modified chitosan, through modification treatment, can improve the antibacterial properties and softness of fabrics; adhesion promoters can improve the adhesion of each component in the antibacterial finishing solution to the fabric, improve the wash fastness of the fabric, and thus improve the antibacterial properties of the fabric; modified metal-organic framework materials have good antibacterial properties and reactivity, and undergo cross-linking reactions with modified chitosan and adhesion promoters. The three work together to improve the wash fastness and antibacterial properties of the fabric.

[0039] 2. Thioctic acid grafted with chitosan can improve the softness of velvet fabrics and, in synergy with adhesion promoters and modified metal-organic framework materials, enhance the wrinkle resistance of dresses.

[0040] 3. Modified chitosan, adhesion promoters, and modified metal-organic framework materials have good antioxidant properties and can capture and quench free radicals. The three work synergistically to enhance the antioxidant properties of the dress. Detailed Implementation

[0108] Performance testing

[0109] (1) The standard GB / T3819-1997 Textile Fabrics Crease Recovery Tester was selected. The M510 fabric crease recovery tester was used to measure the crease recovery. Three 15*40mm samples were cut from the dress. The samples were then folded along the long side and flattened. After applying a negative weight for 5 minutes, half of the sample was taken out and aligned with the crease. It was placed on a movable flat clamp, and the other half was used as a free wing to gradually open it. After releasing the weight for 5 minutes, the crease recovery angle was recorded. The recovery angle was the sum of the average values ​​of the warp and weft recovery angles. The results are recorded in Table 1.

[0110] (2) Select GB / T20944.2-2007 Evaluation of antimicrobial properties of textiles - Part 2: Absorption method as the standard, cut 6 samples of 0.4g each, incubate and wash them, calculate the antimicrobial rate and fill in the measurement results in Table 1.

[0111] (3) Antioxidant performance test: The 2,2-adiazonium-bis(3-ethyl-benzothiazole-6-sulfonic acid) diammonium salt (ABTS) free radical decolorization method was used for determination. ABTS was dissolved in water to prepare a solution with a concentration of 7 mmol / L. Then, the prepared ABTS solution was reacted with a potassium persulfate solution with a concentration of 2.45 mmol / L to obtain the test solution. The test solution was left to stand in the dark for 16 h for later use. Before the test, the test solution was diluted with 0.1 mol / L phosphate buffer solution to an absorbance value of 0.7 at 734 nm. 0.1 g of sample was added to 100 mL of diluted test solution. After standing for 30 min, the absorbance value of ABTS free radical was tested again. The antioxidant activity of the sample was calculated as (A1-A2) / A1, where A1 is the initial absorbance value of ABTS free radical and A2 is the absorbance value of ABTS free radical after the sample was immersed for 30 min.

[0115] As shown in Table 1, the recovery angle of Examples 1-3 is greater than 271.2°, the antibacterial rate of Escherichia coli is greater than 99.3%, the antibacterial rate of Staphylococcus aureus is greater than 98.7%, the antibacterial rate of Candida albicans is greater than 98.9%, and the antioxidant activity is greater than 90.7%. This shows that the velvet fabric diagonally stitched dress prepared in this application has good antibacterial properties, wrinkle resistance and antioxidant properties.

[0116] As shown in Table 1, the differences between Examples 4 and 5 and Example 3 are only as follows: In Example 4, the mass ratio of lipoic acid-grafted chitosan to gemini quaternary ammonium salt is 1:0.15; in Example 5, the mass ratio of lipoic acid-grafted chitosan to gemini quaternary ammonium salt is 1:0.35; in Examples 4 and 5, the angle of recovery is less than 270.3°, the inhibition rate of *Escherichia coli* is less than 98.4%, the inhibition rate of *Staphylococcus aureus* is less than 98.5%, the inhibition rate of *Candida albicans* is less than 98.3%, and the antioxidant activity is less than 89.9%; in Example 3, the angle of recovery is 273.1°, the inhibition rate of *Escherichia coli* is 99.7%, and the inhibition rate of *Staphylococcus aureus* is... The antibacterial rate was 99.5%, the antibacterial rate of Candida albicans was 99.1%, and the antioxidant activity was 91.7%. Compared with Example 3, the antibacterial, anti-wrinkle, and antioxidant properties of Examples 4 and 5 were all reduced. This is because the mass ratio of lipoic acid-grafted chitosan and gemini quaternary ammonium salt was not within the specified range. Too little gemini quaternary ammonium salt has limited antibacterial and antioxidant properties, while too much gemini quaternary ammonium salt will affect the stability and compatibility of modified chitosan. Both will weaken the synergistic effect between modified chitosan, adhesion promoter, and modified metal-organic framework material, thereby reducing the antibacterial, anti-wrinkle, and antioxidant properties.

[0117] As shown in Table 1, the differences between Examples 6 and 7 and Example 3 are only as follows: In Example 6, the mass ratio of tannic acid to graphite phase carbon nitride is 0.35:1, and in Example 7, the mass ratio of tannic acid to graphite phase carbon nitride is 0.55:1. In Examples 6 and 7, the recovery angle is less than 268.5°, the inhibition rate of Escherichia coli is less than 95.5%, the inhibition rate of Staphylococcus aureus is less than 96.3%, the inhibition rate of Candida albicans is less than 95.9%, and the antioxidant activity is less than 87.8%. Compared with Example 3, Examples 6 and 7 show a decrease in antibacterial, anti-wrinkle, and antioxidant properties. This is because the mass ratio of tannic acid to graphite phase carbon nitride is not within the specified range. Too much or too little tannic acid will affect the nanocage structure formed between the adhesion promoter and the modified metal-organic framework material, reducing the synergistic effect of the two, thus reducing the antibacterial, anti-wrinkle, and antioxidant properties.

[0118] As shown in Table 1, the differences between Examples 8 and 9 and Example 3 are only as follows: In Example 8, the lipoic acid-grafted chitosan in the modified chitosan preparation step was replaced with chitosan; in Example 9, the gemini quaternary ammonium salt in the modified chitosan preparation step was replaced with hexadecyltrimethylammonium bromide. The recovery angle in Examples 8 and 9 is less than 264.5°, the inhibition rate against *Escherichia coli* is less than 92.1%, the inhibition rate against *Staphylococcus aureus* is less than 92.5%, the inhibition rate against *Candida albicans* is less than 91.9%, and the antioxidant activity is less than 85.3%. Compared with Example 3, Examples 8 and 9 show a decrease in antibacterial properties, anti-wrinkle properties, and antioxidant properties. This is because if thioctic acid-grafted chitosan is replaced with chitosan, the compatibility of modified chitosan with other components decreases, resulting in limited increase in fabric softness. Replacing the gemini quaternary ammonium salt with hexadecyltrimethylammonium bromide also leads to a decrease in both antibacterial and antioxidant properties. The replacement of any component in the modified chitosan will affect the synergistic effect of the antibacterial finishing agent system, thereby reducing antibacterial, anti-wrinkle, and antioxidant properties.

[0119] As shown in Table 1, the only difference between Example 10 and Example 3 is that in Example 10, the graphitic carbon nitride in the preparation step of the adhesion promoter was replaced with graphene. The recovery angle in Example 10 was 261.7°, the inhibition rate of Escherichia coli was 89.7%, the inhibition rate of Staphylococcus aureus was 89.9%, the inhibition rate of Candida albicans was 89.1%, and the antioxidant activity was 85.2%. Compared with Example 3, the antibacterial, anti-wrinkle, and antioxidant properties of Example 10 all decreased. This is because replacing graphitic carbon nitride with graphene weakens the ability of graphene to catalyze the quenching of bacteria and active free radicals. Any change in the substitution of components in the adhesion promoter will affect the synergistic effect of the antibacterial finishing agent system, thus reducing the antibacterial, anti-wrinkle, and antioxidant properties.

[0120] As shown in Table 1, the only difference between Examples 11 and 12 and Example 3 is that: in Example 11, ferulic acid was not added to prepare the modified metal-organic framework material; in Example 12, the aminated zinc-based metal-organic framework material in the preparation step was replaced with a zinc-based metal-organic framework material. In Examples 11 and 12, the recovery angle was less than 263.3°, the inhibition rate of Escherichia coli was less than 83.9%, the inhibition rate of Staphylococcus aureus was less than 83.4%, the inhibition rate of Candida albicans was less than 83.5%, and the antioxidant activity was less than 84.6%. Compared with Example 3, Examples 11 and 12 showed a decrease in antibacterial, anti-wrinkle, and antioxidant properties. This is because the absence of ferulic acid resulted in a lack of synergistic effect between ferulic acid and the aminated zinc-based metal-organic framework material. The lack of aminated treatment on the zinc-based metal-organic framework material reduced the active groups on its surface, affecting the compatibility and synergistic effect of the antibacterial finishing agent system, thus leading to a decrease in antibacterial, anti-wrinkle, and antioxidant properties.

[0121] As shown in Table 1, the only difference between Comparative Example 1 and Example 3 is that the modified chitosan was replaced with chitosan in Comparative Example 1. The angle of recovery in Comparative Example 1 was 237.5°, the inhibition rate of Escherichia coli was 75.8%, the inhibition rate of Staphylococcus aureus was 76.5%, the inhibition rate of Candida albicans was 75.3%, and the antioxidant activity was 78.2%. Compared with Example 3, Comparative Example 1 showed a significant decrease in antibacterial, anti-wrinkle, and antioxidant properties. This is because replacing the modified chitosan with chitosan and lacking the modification treatment of lipoic acid and gemini quaternary ammonium salt significantly reduced the anti-wrinkle, antibacterial, and antioxidant properties of the modified chitosan. The synergistic effect between the modified chitosan and the adhesion promoter and modified metal-organic framework material was weakened, resulting in a significant decrease in antibacterial, anti-wrinkle, and antioxidant properties.

[0122] As shown in Table 1, the only difference between Comparative Examples 2 and 3 and Example 3 is that the adhesion promoter in Comparative Example 2 was replaced with tannic acid, and the adhesion promoter in Comparative Example 3 was replaced with graphitic carbon nitride. The recovery angle in Comparative Examples 2 and 3 was less than 244.8°, the inhibition rate of Escherichia coli was less than 80.5%, the inhibition rate of Staphylococcus aureus was less than 81.1%, the inhibition rate of Candida albicans was less than 80.9%, and the antioxidant activity was less than 79.7%. Compared with Example 3, Comparative Examples 2 and 3 showed a significant decrease in antibacterial, anti-wrinkle, and antioxidant properties. This is because replacing the adhesion promoter with tannic acid or graphitic carbon nitride disrupts the synergistic effect between tannic acid and graphitic carbon nitride, reduces the stability of the nanocage structure formed with the modified metal-organic framework material, and weakens the synergistic effect between the adhesion promoter and the modified metal-organic framework material, thus significantly reducing the antibacterial, anti-wrinkle, and antioxidant properties.

[0123] As shown in Table 1, the only difference between Comparative Example 4 and Example 3 is that the modified metal-organic framework material was replaced with a zinc-based metal-organic framework material in Comparative Example 4. The recovery angle in Comparative Example 4 was 242.1°, the inhibition rate of Escherichia coli was 80.7%, the inhibition rate of Staphylococcus aureus was 80.1%, the inhibition rate of Candida albicans was 79.3%, and the antioxidant activity was 80.5%. Compared with Example 3, Comparative Example 4 showed a significant decrease in antibacterial, anti-wrinkle, and antioxidant properties. This is because replacing the modified metal-organic framework material with a zinc-based metal-organic framework material resulted in a decrease in the compatibility of the zinc-based metal-organic framework material with the synergistic effect of amylation modification and ferulic acid, which weakened its synergistic effect with the adhesion promoter, thus significantly reducing the antibacterial, anti-wrinkle, and antioxidant properties.
