[0002] With the rapid development of the economy and technology, a wide variety of transportation options have emerged, greatly facilitating people's travel. Among these, vehicle interior products, such as seats, steering wheel covers, gear shift covers, handbrake covers, anti-slip mats, and headrests, are made of genuine leather. However, the processing of genuine leather involves the addition of numerous organic solvents, resulting in high levels of VOCs, which are detrimental to human health. In recent years, the industrial textile industry has continued to flourish, with textiles widely used in the transportation sector. Blended fabrics have gradually replaced genuine leather as the new favorite material for vehicle interiors.

[0003] At present, chemical fiber blended fabrics have low environmental protection, and chemical fibers are non-degradable. In order to actively respond to the call for sustainable development, people's attention has begun to turn to green and environmentally friendly wool natural fibers. Wool natural fibers have good biodegradability, are moisture-absorbent and breathable, and have a soft texture, which can bring great comfort to people. However, the mechanical properties, antibacterial properties and flame retardant properties of existing wool natural fiber blended fabrics cannot well meet the high performance requirements of vehicle interior products. Therefore, it is urgent to propose a high-performance wool natural fiber blended fabric for vehicles to solve the problem of weak mechanical properties, antibacterial properties and flame retardant properties of existing wool natural fiber blended fabrics, so that wool natural fiber blended fabrics can be better used in the field of vehicles, which has the positive significance of green environmental protection. Summary of the Invention

[0004] In order to solve the problem that the existing wool and natural fiber blended fabrics have weak mechanical properties, antibacterial properties and flame retardant properties, the present application provides a high-performance wool and natural fiber blended fabric for vehicles.

[0005] The present application provides a high-performance wool and natural fiber blended fabric for vehicles, which adopts the following technical solution:

[0006] A high-performance wool and natural fiber blended fabric for transportation, formed by interweaving warp and weft yarns;

[0007] The warp yarn is composed of modified wool fiber and carbon fiber in a mass ratio of 1-5:3-5; the weft yarn is composed of modified wool fiber and polylactic acid fiber in a mass ratio of 4-8:3-7;

[0008] The modified wool fiber comprises the following raw materials in parts by weight: 11-15 parts of chitosan, 5-9 parts of succinic acid, 6-8 parts of ginkgo extract, 3-6 parts of sodium phytate, 1-3 parts of xanthan gum, 10-20 parts of wool fiber, and 80-100 parts of deionized water.

[0009] By adopting the above technical scheme, the wool and natural fiber blended fabric of the present application is interwoven with warp and weft yarns, the warp yarns are composed of modified wool fibers and carbon fibers, and the weft yarns are composed of modified wool fibers and polylactic acid fibers; carbon fibers have many advantages such as corrosion resistance, wear resistance, high temperature resistance, high strength, and light weight, which provides an effective guarantee for the mechanical properties of the wool and natural fiber blended fabric; polylactic acid fibers have good elasticity, good moisture absorption, anti-brittle wrinkle, good shape retention, good durability, and good thermal stability, and polylactic acid fibers are good bio-based renewable biodegradable materials; modified wool fibers have significant antibacterial and flame retardant properties, and their mechanical properties are also significantly improved; therefore, the wool and natural fiber blended fabric of the present application has excellent mechanical properties, significant antibacterial and flame retardant properties, and good chemical stability, can be widely used in the field of transportation, is green and environmentally friendly, and has positive significance for sustainable development.

[0010] In addition, the present application modifies the wool fiber, and the modified wool fiber includes wool fiber, chitosan, succinic acid, ginkgo extract, sodium phytate, xanthan gum and other raw materials. Chitosan and ginkgo extract both have excellent antibacterial functions, and chitosan has good film-forming properties, which can form an antibacterial protective film on the surface of the wool fiber; succinic acid can provide an acidic environment and has an antibacterial function; xanthan gum has emulsifying and thickening effects, which can promote the better combination of other components with the wool fiber; in addition, sodium phytate contains a large number of phosphate groups, which can synergistically flame retardant with chitosan; the various components in the modified wool fiber synergistically enhance the performance to form a modified wool fiber with better performance, so that the final wool and natural fiber blended fabric has multiple functions and has broader application prospects in the field of transportation.

[0011] Preferably, the modified wool fiber is prepared by the following method:

[0012] S1. First, chitosan and succinic acid were added to deionized water and fully dissolved; then, ginkgo extract, sodium phytate, and xanthan gum were added to the chitosan, and the pH value was adjusted to 6-8 to obtain a modified solution;

[0013] S2. Add the wool fiber to the modified liquid, stir and react at 40-50° C. and 800-1000 r / min for 40-60 min, filter, and dry to obtain the modified wool fiber.

[0014] By adopting the above technical solution, the present application first adds chitosan and succinic acid into deionized water to protonate the amino groups on the chitosan, and then adds ginkgo extract and sodium phytate into the chitosan. Under the action of xanthan gum, the total ginkgo flavonoids and ginkgo lactones as well as sodium phytate in the chitosan and ginkgo extract can better interact with the wool fiber. The present application also controls various process parameters to greatly improve the antibacterial and flame retardant properties of the modified wool fiber.

[0015] Preferably, the modified wool fiber is also pretreated:

[0016] First, wool fiber, composite alkali and deionized water are mixed in a mass ratio of 1:6-10:20-30, treated at 40-60°C for 30-40 minutes, filtered and dried to obtain alkali-washed wool fiber; then the alkali-washed wool fiber is subjected to plasma treatment at a power of 110-150W and a treatment time of 10-20 minutes to obtain pretreated wool fiber.

[0017] Preferably, the composite base is obtained by mixing sodium citrate and sodium ascorbate in a mass ratio of 1-3:4-8.

[0018] By adopting the above technical solution, the present application first uses a composite alkali to alkali-wash the wool fiber to remove grease on the surface of the wool fiber, and then uses plasma to treat the alkali-washed wool fiber. The exposed wool protein can better interact with the modifying liquid, so that the comprehensive performance of the sheep fiber is more excellent. At the same time, the composite alkali of the present application is obtained by mixing sodium citrate and sodium ascorbate. The alkalinity of the composite alkali is relatively weak. The two synergistically enhance the effect, can effectively remove the grease from the wool fiber, and at the same time will not cause damage to the protein structure of the wool fiber, so that the modified wool fiber has good mechanical properties.

[0019] Preferably, the weft yarn is made by the following method:

[0020] First, the modified wool fiber and the polylactic acid fiber are blended according to a mass ratio to obtain a primary weft yarn; then, the primary weft yarn is treated with a finishing liquid in a two-dipping and two-padding manner, and dried to obtain a weft yarn.

[0021] By adopting the above-mentioned technical solution, the present application blends modified wool fiber and polylactic acid fiber according to a mass ratio, treats the initial weft yarn with a finishing liquid, and dries to obtain the weft yarn, so that the weft yarn can better combine the advantages of both modified wool fiber and polylactic acid fiber, thereby making the comprehensive performance of the final wool and natural fiber blended fabric even better.

[0022] Preferably, the finishing liquid comprises the following raw materials in parts by weight: 11-13 parts of nano-silicon dioxide, 5-8 parts of hemp stalk core powder, 3-6 parts of silane coupling agent, 1-3 parts of tea tree oil, 80-100 parts of ethanol, and 5-9 parts of deionized water.

[0023] Preferably, the finishing liquid is prepared by the following method:

[0025] By adopting the above-mentioned technical scheme, the finishing liquid of the present application contains raw materials such as nano-silica, hemp stalk core powder, tea tree oil, and silane coupling agent. The alcoholyzed silane coupling agent can promote the nano-silica to better combine with the modified wool fiber and polylactic acid fiber in the primary weft yarn, and can also enhance the cohesion between the modified wool fiber and the polylactic acid fiber; the addition of nano-silica significantly improves the mechanical properties of the weft yarn; the hemp stalk core powder has good adsorption function, on the one hand it can absorb VOCs, and on the other hand it can promote the nano-silica to better adsorb to the surface of the fiber; and the hemp stalk core powder has good moisture absorption, breathability and antibacterial functions; tea tree oil is also added, which not only has a softening effect, but also has good antibacterial and antibacterial effects; the present application uses the finishing liquid to treat the primary weft yarn, so that the mechanical properties, antibacterial properties and flame retardant properties of the weft yarn are significantly improved, and the weft yarn has good moisture absorption and breathability.
