Description

Technical Field

[0001] This invention relates to the field of fabrics, specifically to an anti-wrinkle embroidered fiber fabric. Background Technology

[0002] Embroidery fabrics, combining decorative and practical properties, are widely used in clothing, home furnishings, and handicrafts. Cotton-polyester blends, with their skin-friendly, breathable, crisp, and durable characteristics, have become a commonly used base fabric for embroidery. However, cotton-polyester blends have significant wrinkle resistance issues during actual use and processing. They are prone to stubborn creases after folding or crumpling, which not only affects the smoothness of the finished embroidery but also increases the cost of subsequent ironing processes. Furthermore, conventional embroidery fabrics have poor anti-static properties, easily attracting dust and pilling in dry environments due to static electricity. They also lack antioxidant capacity, leading to yellowing and aging after long-term use, which damages the texture of the embroidered pattern.

[0003] Currently, the industry mostly uses single carboxylic acid-based anti-wrinkle finishing agents to treat textile fabrics. Although this can improve wrinkle resistance to some extent, the functionality of these finishing agents is limited, and they cannot simultaneously improve the antistatic and antioxidant properties of the fabric, thus failing to meet the diverse market demands for high-quality embroidered fabrics. Therefore, this invention proposes an anti-wrinkle embroidered fiber fabric. Summary of the Invention

[0004] The purpose of this invention is to provide a wrinkle-resistant embroidered fiber fabric in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: This invention provides an anti-wrinkle embroidery fiber fabric, which is obtained by impregnating a base fiber fabric with an anti-wrinkle finishing agent. The raw materials for preparing anti-wrinkle finishing agents include butanetetracarboxylic acid, diethylene glycol, sodium hypophosphite, coumarin-veratrol complex fermentation extract, fatty acid polyoxyethylene ester, and deionized water.

[0006] As a further optimization of the present invention, the basic fiber fabric is made by blending cotton fiber and polyester fiber in a mass ratio of 1:(1-1.5).

[0007] As a further optimization of the present invention, the raw materials for preparing the anti-wrinkle finishing agent, by weight, include: 30-40 parts of butanetetracarboxylic acid, 6-10 parts of diethylene glycol, 30-35 parts of sodium hypophosphite, 4-6 parts of coumarin-veratrol compound fermentation extract, 1.5-2.5 parts of fatty acid polyoxyethylene ester, and 60-80 parts of deionized water.

[0008] As a further optimization of the present invention, the preparation method of the guar bean-veratrol compound fermentation extract is as follows: guar bean seeds and veratrol rhizomes are dried and pulverized separately, the obtained guar bean powder and veratrol powder are mixed evenly to obtain compound plant powder, the compound plant powder is added to the liquid fermentation culture medium, and after high-pressure steam sterilization, a compound bacterial agent is inoculated. After fermentation is completed, the fermentation product is centrifuged, the fermentation liquid is collected, concentrated and spray-dried to obtain the guar bean-veratrol compound fermentation extract.

[0009] As a further optimization of the present invention, the mass ratio of coumarin powder to veratrum powder in the compound plant powder is 1:(0.5-2), and the amount of compound plant powder added to the liquid fermentation medium is 5-8g / 100mL.

[0010] As a further optimization of the present invention, the compound microbial agent is prepared by mixing activated Lactobacillus paracasei liquid, Saccharomyces cerevisiae liquid, and Aspergillus oryzae liquid in a volume ratio of 1:1:1.

[0011] As a further optimization of the present invention, the inoculum amount of the compound microbial agent is 5-10% (v / v).

[0012] As a further optimization of the present invention, the fermentation conditions are: 28-32℃ and 180-220rpm for 5-8 days.

[0013] As a further optimization of the present invention, the preparation method of the anti-wrinkle finishing agent is as follows: under room temperature conditions, butanetetracarboxylic acid, diethylene glycol and sodium hypophosphite are added to deionized water and stirred until completely dissolved. Then fatty acid polyoxyethylene ester is added and stirred until uniform. Finally, coumarin-veratrol compound fermentation extract is added and stirred until the system is uniform to obtain the anti-wrinkle finishing agent.

[0014] As a further optimization of the present invention, the conditions for padding are as follows: the anti-wrinkle finishing agent is mixed and diluted with deionized water at a volume ratio of 1:(5-10) to obtain a finishing solution. The base fiber fabric is subjected to two dips and two pads at 40-60°C with a padding rate of 70-90% and a total padding time of 10-15 minutes. The base fiber fabric after padding is pre-dried at 80-90°C for 3-5 minutes and then baked at 150-160°C for 1-3 minutes.

[0015] The beneficial effects of this invention are as follows: This invention provides a fabric processing solution for padding a base fabric with an anti-wrinkle finishing agent containing a coumarin-veratrol complex fermentation extract. The coumarin-veratrol complex fermentation extract improves the anti-wrinkle, antistatic, and antioxidant properties of the fabric through the synergistic fermentation of coumarin, veratrol, and a complex microbial agent composed of Lactobacillus paracasei, Saccharomyces cerevisiae, and Aspergillus oryzae, thereby effectively enhancing the fabric's durability.

[0025] Comparative Example 2 Compared with Example 3, the difference in Comparative Example 2 is that, in Comparative Example 2, when preparing the anti-wrinkle finishing agent, a single guar fermented extract was used to replace the guar-veratrol complex fermented extract, and the amount remained the same. The preparation method of the guar fermented extract was the same as that of the guar-veratrol complex fermented extract, except that the complex plant powder was replaced with an equal amount of guar powder.

[0026] Comparative Example 3 Compared with Example 3, the difference of Comparative Example 3 is that in Comparative Example 3, when preparing the anti-wrinkle finishing agent, a single Veratrum fermentation extract was used to replace the coumar-veratrum complex fermentation extract, and the amount remained the same. The preparation method of the Veratrum fermentation extract was the same as that of the coumar-veratrum complex fermentation extract, except that the complex plant powder was replaced with an equal amount of Veratrum powder.

[0027] Comparative Example 4 Compared with Example 3, Comparative Example 4 differs in that the compound microbial agent used in Comparative Example 4 is a mixture of Lactobacillus paracasei liquid and Aspergillus oryzae liquid in a volume ratio of 1:1, and the dosage is the same as in Example 3.

[0028] 2. Performance testing of wrinkle-resistant embroidered fiber fabrics Samples of equal size were cut from the finished fabrics obtained in Examples 1-3 and Comparative Examples 1-4. A base fabric (same as in Example 3) that had not been treated with any anti-wrinkle finishing agent was used as a blank control for performance testing. The testing items and methods are as follows: (1) Wrinkle resistance test: Referring to AATCC 66-2008 "Fabric wrinkle recovery: recovery angle method", the sample after standard atmospheric equilibrium is folded and pressed to form a crease. After release, the opening angle of the two folds at the crease is measured. The larger the angle, the better the wrinkle recovery performance of the fabric. The test results are usually recorded separately in the warp and weft directions, and the sum of the two values ​​is used to characterize the overall wrinkle resistance. (2) Antistatic performance test: Under 30% humidity conditions, the antistatic performance of each fabric sample was tested according to GB / T 12703.1-2021 "Textiles - Test methods for electrostatic properties - Part 1: Corona charging method". The electrostatic voltage half-life was used as the test index (Level 1: half-life ≤ 6s, Level 2: 6s < half-life ≤ 15s, Level 3: 15s < half-life ≤ 30s, Level 4: 30s < half-life ≤ 60s, Level 5: > 60s).

[0029] (3) Antioxidant activity detection: Weigh 0.5g of fabric sample, add 20mL of 50% ethanol solution, and extract by shaking in a water bath at 60℃ for 1h. After filtration, obtain the sample extract. Take 2mL of the extract, add 2mL of 0.1mmol / L DPPH ethanol solution, mix well, and react in the dark for 30min. Measure the absorbance at 517nm and record it as A1. Take 2mL of the extract, add 2mL of anhydrous ethanol, react under the same conditions, and measure the absorbance, record it as A2. Take 2mL of anhydrous ethanol, add 2mL of 0.1mmol / L DPPH ethanol solution, react under the same conditions, and measure the absorbance, record it as A0. Use the fabric prepared with blank culture medium as a control. The antioxidant activity of the sample is characterized by the DPPH free radical scavenging rate. The calculation formula is as follows: ; In the formula: A1 is the absorbance of the sample group; A2 is the background absorbance of the sample; A0 is the absorbance of the blank control group.

[0030] The test results are shown in Table 1. From the table, we can see that: (1) In Examples 1-3, all data of the sample fabrics were significantly better than those of the blank control. This result indicates that padding the fabric with an anti-wrinkle finishing agent can effectively improve the anti-wrinkle performance, antistatic performance and antioxidant activity of the fabric. (2) Compared with Example 3, the data of the fabrics in Comparative Examples 1-3 were relatively poor. Among them, the difference in antistatic performance of the fabrics was particularly significant. This result indicates that the tannin-veratrol compound fermented extract is the core component of the anti-wrinkle finishing agent that improves the antistatic performance of the fabric, and the functionality of the tannin-veratrol compound fermented extract is related to the synergistic fermentation between tannin and veratrol. (3) Compared with Example 3, in Comparative Example 4, although the wrinkle resistance of the fabric was still at a high level, the antioxidant activity was significantly worse. This result indicates that the three-strain compound fermentation is a necessary condition for preparing a high-efficiency compound extract. The coumarin-veratrol compound fermentation extract obtained under the synergistic effect of Lactobacillus paracasei, Saccharomyces cerevisiae and Aspergillus oryzae can be applied to the anti-wrinkle finishing agent and then used to treat the fabric to achieve the improvement effect of both the wrinkle resistance and antioxidant properties of the fabric.

[0031] Table 1: Performance test results of sample fabrics 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.
