Description

Technical Field

[0001] The invention relates to the technical field of blended material preparation, and in particular to a blended material for home textiles which is easy to clean, a production process and an application thereof. Background Art

[0002] As people's living standards continue to improve, the quality and functionality of home textile products are becoming more and more stringent. Home textiles, as items that are in close contact with us in daily life, include bedding, curtains, sofa covers, etc. They are easily stained, and frequent washing will affect their appearance, texture and service life. Therefore, the development of home textile materials that are easy to clean has become a key issue in the industry.

[0003] In the traditional material structure of the home textile market, natural fibers such as cotton, wool, and silk are widely used. Cotton is skin-friendly, comfortable, and has good moisture absorption and breathability, but its fiber structure is loose, stains can easily penetrate into the interior, it is easy to shrink and deform after washing, and it will turn yellow and hard after repeated washing; wool is excellent in warmth but delicate, and it is difficult to thoroughly clean after being stained with water and oil stains. The dry cleaning cost is high and chemical reagents can easily damage the fiber; silk is smooth and delicate, but its strength decreases when it comes into contact with water, and it is difficult to clean after stains are attached. Even the conventional washing process may cause fiber breakage and degumming, reducing the grade of the product. Therefore, the common home textile fabrics on the market currently face the following challenges: the surface structure of traditional textiles is relatively rough, and it is easy to absorb dust, oil and other pollutants, and it is difficult to clean thoroughly; after repeated washing, many home textile materials will fade, deform, and other problems, affecting the service life; during long-term use, especially in humid environments, ordinary home textile materials are prone to breed bacteria and mold, which is not conducive to health and hygiene.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The antibacterial modified polyester fiber in the blended material of the present invention has undergone a special preparation process, and its structure is relatively stable. It is not easy to fade due to chemical reactions caused by contact with water, detergents, etc. during washing. At the same time, the polyester fiber itself has good chemical stability, strong washing resistance, and is not easy to fade. The polyester fiber in the blended material has high strength and modulus and is not easy to deform; cotton fiber has good flexibility and hygroscopicity, and is comfortable to wear; the blended yarn of antibacterial modified polyester fiber and carbon fiber has both antibacterial properties and certain mechanical strength. The three fibers are blended together to complement each other, so that the blended material can still maintain good shape stability after multiple washings.

[0015] 2. The composite antibacterial agent of the present invention contains silver-zinc oxide nanoparticles. Silver itself has a strong broad-spectrum antibacterial ability, can combine with active substances such as proteins and enzymes in microorganisms, destroy their normal physiological functions, inhibit or even kill bacteria, fungi and other microorganisms, and zinc oxide nanoparticles also have antibacterial activity. The two synergistically enhance the resistance of the antibacterial modified polyester fiber to various common pathogens such as Escherichia coli and Staphylococcus aureus. Then, tetraethyl orthosilicate is added to form silicon dioxide and silver-zinc oxide nanoparticles for compounding. During the hydrothermal crystallization process, a stable and close interaction is formed between silver-zinc oxide and silicon dioxide, so that the chemical stability of the composite antibacterial agent is significantly improved. Silicon dioxide has good chemical inertness and can protect silver-zinc oxide nanoparticles from external environmental factors to a certain extent, thereby extending the service life of the composite antibacterial agent. At the same time, the presence of silicon dioxide can provide more active sites for silver and zinc oxide, promote the contact between the antibacterial components and bacteria, and improve the antibacterial effect of the antibacterial modified polyester fiber.

[0016] 3. The hydrophobic and oleophobic nanoparticles and siloxane components in the hydrophobic and oleophobic finishing agent of the present invention can fill the tiny pores and uneven places on the fiber surface during the finishing process, making the fiber surface smoother. On the one hand, the friction coefficient of the fiber surface is reduced, making the fabric feel softer and smoother; on the other hand, the perfluoropolyether, perfluorooctanoic acid and other fluorine-containing compounds in the hydrophobic and oleophobic nanoparticles have extremely low surface energy, which can form a uniform hydrophobic and oleophobic film on the fiber surface, which makes the surface of the blended material not easily wetted by water and oil stains, and the stains are difficult to adhere to. Even if there are stains, they are easy to roll or slide on the surface, thereby greatly improving the anti-fouling performance of the material, which is convenient for daily cleaning. At the same time, after the hydrophobic and oleophobic finishing agent is impregnated, a low surface energy coating can be formed on the fiber surface, and the contact angle of water and oil on its surface increases, so that it is difficult to wet and adhere, thereby greatly improving the anti-fouling ability of the blended material, which is convenient for cleaning.

[0025] Comparative Example 3 Compared with Example 1, the difference of Comparative Example 3 is that Comparative Example 3 removes steps S1-S2, replaces the antibacterial modified polyester fiber in S5.1 with polyester fiber, and prepares an easy-to-clean blended material without changing the other steps, which is recorded as Comparative Example 3.

[0026] Determination of oil and water repellency: Oil repellency determination: Tested according to GB / T19977-2014. Washing method: Wash and dry according to GB / T8629-2017.

[0027] Water repellency test: The contact angle of the fabric was measured using a JCY 2 contact angle meter (Shanghai Fangrui Instrument Co., Ltd.).

[0028] The oil repellency and water repellency of Examples 1-3 and Comparative Examples 1-2 were tested, and the oil repellency and water repellency of the blended material, which was easy to clean, were tested again after washing it 20 times.

[0029] The measurement results are shown in Table 1.

[0030] Table 1. Results of oil repellency and water repellency measurements for Examples 1-3 and Comparative Examples 1-2

[0031] It can be seen from the data in Table 1 that the oil repellency level and water contact angle of Comparative Examples 1 and 2 are worse than those of the embodiment, and the oil repellency level and water contact angle of Comparative Example 2 are better than those of Comparative Example 1, indicating that the hydrophobic and oleophobic finishing agent can improve the hydrophobic and oleophobic ability of the blended material, thereby greatly improving the anti-fouling ability of the blended material, which is convenient for cleaning. At the same time, the addition of hydrophobic and oleophobic nanoparticles can further improve the hydrophobic and oleophobic ability of the blended material. After washing 20 times, the oil repellency level and water contact angle do not change much, indicating that the blended material prepared by the present invention still maintains good anti-fouling ability after multiple washings, which is convenient for cleaning.

[0032] Antimicrobial test: The oscillation method (GB / T20944.3-2008) was used for testing.

[0033] The antibacterial property of the easy-to-clean blended materials prepared in Examples 1-3 and Comparative Example 3 was measured. The antibacterial property of the easy-to-clean blended materials was measured again after washing them 20 times.

[0034] The measurement results are shown in Table 2.

[0035] Table 2. Antibacterial test results of Examples 1-3 and Comparative Example 3

[0036] It can be seen from the data in Table 2 that the data of Comparative Example 3 is significantly lower than that of the embodiment, indicating that the use of composite antibacterial agent to modify polyester fiber greatly enhances the resistance of antibacterial modified polyester fiber to Escherichia coli and Staphylococcus aureus, so that the prepared blended material has good antibacterial properties.
