Technical Field

The invention relates to the technical field of automotive interiors, in particular to a low-odor cotton felt material, a cotton felt sheet, a vehicle interior and a vehicle.

Background

The cause of the air quality problem in the automobile is simple, and the air quality problem is mainly harmful substances released by the automobile interior trim material. The automotive interior makes the car more pleasing to the eye, also makes the car more have the practicality simultaneously, and automotive interior material has occupied great proportion in automotive interior material, including automotive carpet, ceiling felt, for the coat and hat shelf blanket, suitcase blanket etc. the car space is narrow and small, the leakproofness is good, air and driver and crew direct contact in the car, and air pollution has great influence to driver and crew's health in the car. Although the degree of air pollution in the vehicle may be reduced with the continuous release of harmful substances in the vehicle body material, in general, the time interval from the completion of the manufacture to the delivery to the user is only a few days to a few weeks, and the storage and transportation process of the vehicle is not enough to fully release and remove the pollution in the vehicle, because the passenger compartment is in a closed state isolated from the external environment during the storage and transportation process of the vehicle. When a user starts to use a new vehicle, the air pollution in the vehicle is the most serious time. Although various methods and technical means are currently on the market which claim to eliminate pollution in the vehicle, the effectiveness is often difficult to verify. The user is unlikely to leave the vehicle idle until the pollutants in the vehicle are reduced before the vehicle starts to use a new vehicle, and therefore sensitive individuals including pregnant women, patients, children and the like are likely to be affected by the pollutants in the vehicle in many cases.

AutomobileIs an indispensable vehicle in people's daily life, and in particular, almost every family has a private car in the current society. Along with the development of the automobile industry and the improvement of the environmental protection consciousness of people, the requirement of people on the quality of air in the automobile is continuously improved, and the main reasons are that the environmental consciousness and the self-protection consciousness of social public are continuously improved, and the air quality in the automobile directly related to the health is concerned increasingly; secondly, the requirements of consumers on the comfort and the perception of the automobile are higher and higher, and automobile manufacturers and decorating enterprises meet the requirements of the consumers and continuously improve the decoration level and the carriage tightness of facilities in the automobile to meet the requirements of the consumers when designing and producing the automobile and providing automobile decoration services, so that air pollutants in the automobile are easier to accumulate to generate pollution; the components of air pollutants in the vehicle are complex and contain VOCs and other volatile substances, so that countries and various vehicle enterprises begin to pay attention to the quality of air in the vehicle and set control limit values of VOCs (volatile organic compounds, VOCs for short) of materials of relevant vehicle and parts. The volatile organic compound is CO and CO₂、H₂CO₃Metal carbides, metal carbonates and ammonium carbonate, any carbon compound that participates in atmospheric photochemical reactions. With the increasing requirements of automobile consumers on the environmental protection performance and the odor in the carriage, in order to meet the stricter limit requirements of the odor VOC, environmental protection materials are required to be developed continuously.

The cotton felt sheet currently used as the automobile interior in the market mainly has the following problems: the jean cotton material is adopted, and because the recycled jean leftover materials are used, the materials often contain a large amount of coloring agents, the odor of the materials is sour, the problems of high VOC content, pungent odor volatilization and the like exist, the requirements of current consumers cannot be met, and the materials cannot meet the related odor requirements along with the continuous improvement of the environment-friendly odor requirements; the pure polyester cotton felt is made of pure polyester fibers or recycled bottle flakes, which are used as raw materials, and has high cost, and the pure polyester fiber materials have poor sound insulation performance due to the fact that the common polyester fibers are thick.

In view of the above, there is a need to provide a low odor cotton felt material and a cotton felt sheet, a vehicle interior and a vehicle to solve the above technical problems.

Disclosure of Invention

The present invention is directed to a low odor cotton felt material, a cotton felt sheet, a vehicle interior and a vehicle, which overcome the above-mentioned problems of the prior art.

Further, the polyester fiber has a fiber denier of 4-12D.

Further, the low-odor cotton felt material also comprises an oiling agent, wherein the oiling agent accounts for 0.1-1 part by weight.

Further, the low-odor cotton felt material also comprises a fiber flame retardant, and the weight part of the fiber flame retardant is 0.1-1 part.

The invention provides a low-odor cotton felt sheet, which is obtained by opening, cotton mixing, cotton feeding, carding, lapping and molding the low-odor cotton felt material.

A third aspect of the invention provides a vehicle interior made using the low-odor cotton felt sheet described above.

A fourth aspect of the invention provides a vehicle including the vehicle interior described above.

The implementation of the invention has the following beneficial effects:

1. the recycled white cotton fiber is adopted, and the material has the characteristics of low cost and fine fiber, can further remove oil stains and aldehyde ketone substances in the recycled cotton fiber through a washing and baking process, and has the advantages of low odor and low VOC;

2. the invention adopts the low melting point fiber material with better smell and the polyester fiber to be compounded with the white cotton fiber, has better smell compared with the denim cotton material adopted in the prior art, and has better sound insulation compared with the prior pure polyester cotton felt;
