Description

Technical Field

[0001] This invention belongs to the field of fabric technology, specifically relating to a graphene-based abrasion-resistant windbreaker fabric and its preparation method. Background Technology

[0002] In recent years, outdoor sports (hiking, mountaineering, camping, etc.) have become increasingly popular. Among outdoor sportswear, waterproof jackets are indispensable. Unlike regular clothing, waterproof jackets can provide effective protection for outdoor athletes in harsh weather conditions, and the fabric of the waterproof jacket is the key factor that determines its performance.

[0003] Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms arranged in a special honeycomb lattice. It has excellent electrical conductivity, thermal conductivity, and antibacterial properties. When graphene is applied to textile fabrics, it can endow the fabrics with antistatic, warm, antibacterial, and UV protection properties. Therefore, the research and application of graphene in textiles are increasing.

[0004] For example, Chinese patent CN 119754037 A discloses a down jacket fabric containing graphene fibers and its preparation method. This technical solution involves mixing graphene oxide and gelatin, followed by vacuum freeze-drying to form a porous aerogel. The composite graphene oxide aerogel is then modified by grafting tetraphenylethylene onto it, improving the fabric's warmth and abrasion resistance. Another technical solution modifies nano-silica by grafting hydroxyl-terminated polybutadiene onto it. The hydroxyl-terminated polybutadiene contains hydroxyl groups at both ends, which improves the dispersion of nano-silica in the finishing solution and prevents agglomeration. Simultaneously, the hydroxyl-terminated polybutadiene molecule contains alkyl long-chain structures, which possess excellent flexibility and phase change energy storage properties, further enhancing the fabric's warmth and abrasion resistance.

[0005] Chinese patent CN 117644695 A discloses a high-strength school uniform fabric. This high-strength fabric consists of an abrasion-resistant layer and an inner lining. The abrasion-resistant layer is composed of a blend of the following fibers by weight: 60-100 parts modified polyester fiber, 10-15 parts spandex fiber, and 10-20 parts nylon fiber. The inner lining is a blend of wool and cotton fibers. This technical solution, by adding graphene-modified polyester fiber to the school uniform fabric, effectively improves the mechanical properties of the polyester fiber, enhancing its abrasion resistance and strength. Simultaneously, the graphene-modified polyester fiber exhibits a 99% antibacterial rate against Escherichia coli, Staphylococcus aureus, and Candida albicans, demonstrating excellent antibacterial effects. Furthermore, the high-density fabric's microporous structure effectively prevents mite intrusion, while the thermoplastic polyurethane film coating ensures that the inner lining fabric fits snugly against the skin without causing harm, while also providing strong breathability.

[0006] However, none of the above technical solutions can meet the abrasion resistance requirements of the national standard GB / T32614-2023 "Outdoor Sports Clothing and Windbreakers". Summary of the Invention

[0079] SEM images of the wear-resistant layer on the surface of the prepared base fabric are as follows: Figure 2 As shown.

[0080] Comparative Example 1

[0081] This comparative example provides a graphene-based abrasion-resistant jacket fabric, which differs from Example 2 only in that the abrasion-resistant agent is entirely fluorinated graphene; all other aspects are the same.

[0082] SEM images of the wear-resistant layer on the surface of the prepared base fabric are as follows: Figure 3 As shown.

[0083] Comparative Example 2

[0084] This comparative example provides a graphene-based abrasion-resistant jacket fabric, which differs from Example 2 only in that the abrasion-resistant agent is graphene oxide and cubic boron nitride in a mass ratio of 4:1; the graphene oxide has a sheet diameter of 10-50 μm, 1-2 layers, and was purchased from Suzhou CarbonFeng Graphene Technology Co., Ltd., with specifications of industrial-grade graphene oxide; all other aspects are the same.

[0085] Comparative Example 3

[0086] This comparative example provides a graphene-based abrasion-resistant jacket fabric, which differs from Example 2 only in that the abrasion-resistant agent is graphene oxide and hexagonal boron nitride in a mass ratio of 4:1; the particle size of the hexagonal boron nitride is 2-20μm, purchased from Shandong Jingyi New Material Co., Ltd., model: SW; all other aspects are the same.

[0087] Comparative Example 4

[0088] This comparative example provides a graphene-based abrasion-resistant jacket fabric, which differs from Example 2 only in that the abrasion-resistant agent is graphene oxide and nano-alumina in a mass ratio of 4:1; the nano-alumina has a particle size of 30-50mm and was purchased from Suzhou Baird New Material Technology Co., Ltd., model: BRD001-N20; all other aspects are the same.

[0089] Comparative Example 5

[0090] This comparative example provides a graphene-based abrasion-resistant jacket fabric, which differs from Example 2 only in that the vinyl POSS content is 0 parts by weight; all other aspects are the same.

[0091] Comparative Example 6

[0092] This comparative example provides a graphene-based abrasion-resistant jacket fabric, which differs from Example 2 only in that vinyl POSS is replaced with an equal mass of polymethylhydrosiloxane, which was purchased from Hubei Longsheng Sihai New Material Co., Ltd., model: SH-202; all other aspects are the same.

[0093] The following performance tests were conducted on the abrasion-resistant jacket fabrics of Examples 1-2 and Comparative Examples 1-6:

[0094] Performance Test 1: Abrasion resistance and hydrostatic pressure were tested according to GB / T 32614-2023 standard.

[0095] Performance Test 2: The abrasion resistance and hydrostatic pressure performance of the abrasion-resistant jacket fabric were tested after 100 washes using the washing method of the color fastness tester in GB / T 32614-2023 standard.

[0096] The test results are shown in Table 1.

[0097] Table 1. Performance test results of abrasion-resistant waterproof jacket fabrics from Examples 1-2 and Comparative Examples 1-6.

[0098]

[0099] Table 1 shows that the abrasion resistance of the abrasion-resistant jacket fabrics obtained in Examples 1 and 2 is greater than 25,000 cycles before and after soaping, and the hydrostatic pressure is greater than 50 kPa before and after soaping.

[0100] The absence of cubic boron nitride in Comparative Example 1 resulted in a significant decrease in the abrasion resistance of the abrasion-resistant jacket fabric both before and after soaping. Furthermore, although the abrasion-resistant agent was entirely fluorinated graphene, its hydrostatic pressure was also significantly lower than in Example 2, especially after soaping. This may be due to a decrease in the density of the abrasion-resistant layer, which can be observed from… Figure 3 It can also be seen that;

[0101] In Comparative Example 2, fluorinated graphene was replaced with graphene oxide, and in Comparative Example 3, cubic boron nitride was replaced with hexagonal boron nitride. The abrasion resistance and hydrostatic pressure of the abrasion-resistant jacket fabric decreased significantly before and after soaping, indicating that specific graphene and boron nitride are required to achieve the effects of Examples 1 and 2 of this invention.

[0102] In Comparative Example 4, cubic boron nitride was replaced with nano aluminum oxide. The abrasion resistance and hydrostatic pressure of the abrasion-resistant jacket fabric decreased significantly before and after soaping. This indicates that the selection of abrasion-resistant agent is crucial, and not just any abrasion-resistant agent can achieve the effects of Examples 1 and 2 of this invention.

[0103] In Comparative Example 5, where vinyl POSS was absent, the abrasion resistance and hydrostatic pressure of the abrasion-resistant jacket fabric decreased significantly before and after soaping. This indicates that vinyl POSS can work together with abrasion-resistant agents in this invention to improve the abrasion resistance, hydrostatic pressure, and soaping resistance of the abrasion-resistant jacket fabric.

[0104] In Comparative Example 6, when vinyl POSS was replaced with polymethylhydrosiloxane, the abrasion resistance and hydrostatic pressure of the abrasion-resistant jacket fabric decreased significantly before and after soaping. This indicates that vinyl POSS works better with the abrasion-resistant agent of this invention than polymethylhydrosiloxane, and can better improve the abrasion resistance, hydrostatic pressure, and soaping resistance of the abrasion-resistant jacket fabric.

[0105] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
