Description

Technical Field

[0001] The invention relates to the technical field of jacquard fabrics, and in particular to a functional plant fiber jacquard fabric and a manufacturing process thereof. Background Art

[0002] In recent years, with the improvement of people's living standards, people's demand for fabrics has gradually increased, and jacquard fabrics have gradually come into people's field of vision. Jacquard fabrics are a kind of fabric with patterns formed by changes in warp and weft organizations. They have the advantages of exquisite patterns, good air permeability, and high color fastness. They are often used in high-end clothing, shoes and hats, home accessories and other fields.

[0003] In the context of today's rapid economic and technological development, consumers' demands for jacquard fabrics are becoming increasingly diversified, and the functionality of jacquard fabrics has also received more and more attention. Ordinary jacquard fabrics have the defect of poor antibacterial performance. Due to the large specific surface area and hygroscopicity of jacquard fabrics, they are easy to become a good medium for the growth and reproduction of microorganisms such as bacteria and fungi. Especially under the nourishment of suitable temperature, relative humidity and sweat and other human secretions, microorganisms will multiply rapidly, resulting in the formation of plaques on the fabrics, and then causing mildew, brittleness and even deterioration. In addition, the decomposition of bacteria on the fabrics will not only cause the generation of odor, but may also cause health problems such as skin infections and allergies, which greatly limits the application and development of jacquard fabrics. Therefore, further improving the antibacterial properties of jacquard fabrics has become a hot research topic in the current fabric field.

[0004] The invention patent with announcement number CN104264444B discloses a health-care bamboo fiber fabric. The invention prepares an environmentally friendly antibacterial solution by electrostatically spraying an antibacterial solution on the surface of bamboo fiber, and then microwave treatment, dyeing, color spinning, jacquard, and printing. In addition to making the bamboo fiber have higher antibacterial and bactericidal capabilities and better stability and dispersion performance, it can also prevent shedding while giving the fabric greater adhesion, increase the bactericidal properties of the fabric, and the jacquard quality is stable and high-grade. Therefore, the jacquard fabric can be modified by adding optimized components in a targeted manner to prepare additives with excellent antibacterial properties to prepare antibacterial jacquard fabrics.

[0035] Step I: Add 5 g of dimethyldiallylammonium chloride and dimethyl sulfoxide solution to a nitrogen-protected reactor, stir evenly, then add 2.8 g of 2,3-dimercaptosuccinic acid and 0.1 g of benzoin dimethyl ether to the reactor, mix evenly, place the system under an ultraviolet lamp with a wavelength of 365 nm, irradiate for 6 hours, and remove the solvent by vacuum distillation to obtain a modified quaternary ammonium salt polymer;

[0036] The modified quaternary ammonium salt polymer was analyzed by infrared spectroscopy using a Bruker TENSOR 27 Fourier transform infrared spectrometer. Figure 1 As shown by Figure 1 It can be seen that in the infrared spectrum of the modified quaternary ammonium salt polymer, 1740 cm -1 The absorption peak of the carboxyl group C=O appears at 1375 cm -1 The absorption peak of CN in quaternary ammonium salt appears at 1195 cm -1 The CSC absorption peak appears at

[0037] Step II: Add 5 g of the modified quaternary ammonium salt polymer to a 60% ethanol aqueous solution by volume, stir evenly, then add 1.2 g of zinc nitrate to the system, turn on the heating, wait until the system temperature reaches 55° C., stir mechanically for 15 h, and filter out the solid material under reduced pressure to obtain an intermediate material;

[0038] Step III: Disperse 4 g of porous vermiculite with an average particle size of 4 μm in deionized water, add 3.4 g of the intermediate material, and ultrasonically treat it at an ultrasonic frequency of 45 kHz for 6 hours at room temperature. Filter and separate the solid material, wash the solid material, and vacuum dry it to obtain an antibacterial modified component.

[0039] Technical principle: In the antibacterial modified component, firstly, under the action of benzoin dimethyl ether and ultraviolet light, the unsaturated olefinic functional groups in the structure of dimethyl diallyl ammonium chloride can undergo continuous click reactions with the thiol groups in the structure of 2,3-dimercaptosuccinic acid, and the molecular chain continues to extend, eventually forming a polymer containing a large number of quaternary ammonium salts and carboxyl groups in the structure, that is, a modified quaternary ammonium salt type polymer; secondly, the carboxyl groups in the structure of the modified quaternary ammonium salt type polymer can produce efficient complexation with zinc ions, thereby The zinc ions are stably immobilized in the structure of the modified quaternary ammonium salt polymer to obtain an intermediate material; then, in an aqueous solution, the porous vermiculite exhibits negative charge, and the structure of the intermediate material contains a large number of quaternary ammonium cations, which exhibits positive charge, so there is an electrostatic adsorption effect between them. At the same time, under the action of ultrasound, the intermediate material will flow into the pores of the porous vermiculite, so that under the dual effects of electrostatic action and ultrasound, the intermediate material will be densely concentrated on the surface and gaps of the porous vermiculite to obtain an antibacterial modified component.

[0090] Performance Testing

[0091] The jacquard fabrics prepared in Examples 1 to 3 of the present invention and Comparative Examples 1 to 4 were made into samples that met the specifications. The unwashed samples and the samples washed 50 times were tested for their antibacterial properties according to GB / T 20944.3-2008 "Evaluation of Antibacterial Properties of Textiles Part 3: Oscillation Method". The test bacteria were Escherichia coli. The washing method was performed according to the washing method of the washing color fastness tester in GB / T 20944.3-2008.

[0092] Table 1 - Performance Test

[0093]

[0094] As can be seen from Table 1, the jacquard fabrics prepared in Examples 1 to 3 have a high antibacterial rate and excellent antibacterial properties. After the samples were washed 50 times, the antibacterial rate decreased slightly. It is speculated that this is because the added antibacterial modified component has a good antibacterial effect and sustained-release performance. The jacquard fabrics prepared in Comparative Examples 1 and 2 were only added with modified quaternary ammonium salt polymers and zinc nitrate, respectively. The antibacterial properties of the samples were average. It is speculated that this is because the organic-inorganic synergistic antibacterial effect cannot be exerted, resulting in a decrease in the antibacterial properties of the samples, and After washing 50 times, the antibacterial rate of the sample decreased significantly; in the jacquard fabric prepared in Comparative Example 3, intermediate materials and porous vermiculite were added, and the antibacterial rate of the sample was high, with excellent antibacterial properties, but the antibacterial rate of the sample was low after washing 50 times. It is speculated that this is because the intermediate material and the porous vermiculite were not treated, and the sustained-release antibacterial effect could not be exerted, resulting in a decrease in the antibacterial properties of the sample after washing 50 times; no antibacterial modified component was added to the jacquard fabric prepared in Comparative Example 4, so the performance of the sample was the worst.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner.
