FLOORING MADE FROM TEXTILE WASTE

Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of floorings, in particular to a textile waste regenerated flooring and a preparation method thereof.BACKGROUND ART

[0002] Textile wastes are from many sources. During the processing of clothing and raw materials, due to chemical operations and machining, waste fabrics are produced inevitably. These fabrics are less contaminated, and thus need a pre-treatment procedure which is relatively simple. Waste clothing, carpets, and bed sheets have become major sources of the textile wastes, and are of enormous quantity, resulting in that their recycling is time-consuming and laborious. However, no matter what kind of product, the recycling can save textile raw materials and reduce environmental pollution.

[0003] CN113583395A discloses a fiber-plastic composite material prepared from mixed waste textiles, a preparation method and application thereof, and relates to the technical field of recycling of waste textiles. The fiber-plastic composite material is prepared from preparation raw materials comprising mixed waste textiles and a thermoplastic resin through smashing, low-temperature solid-phase method extrusion granulation and cold-top method extrusion molding in sequence, wherein the treatment temperature of the low-temperature solid-phase method extrusion and the cold-top method extrusion does not exceed 230 °C.

[0004] After the textile waste is discarded as trash, if it is incinerated, not only will coals, electric power, and other energy sources be consumed, but incineration will also produce a large quantity of pollutants, including carbon dioxide and ash after combustion; if it is landfilled, not only is the land occupied, but produced hazardous substances also contaminate water and soil. Therefore, in the prior art, regenerated chemical fibers are produced from the textile waste by a chemical method, and then used to manufacture regenerated fiberboard materials by carding, cross lapping, needle punching, and strengthening processes. However, this method has high requirements on raw materials of textile wastes, and it is necessary to sort out chemical fiber materials such as pure polyesters; raw materials of textile waste that are not chemical fiber materials cannot be recycled, which makes it impossible to realize a large-scale resource utilization of the textile waste.SUMMARY

[0005] In view of the above, an object of the present disclosure is to provide a textile waste regenerated flooring and a preparation method thereof. In the present disclosure, a textile waste is used to prepare a flooring, and there is no limitation on the source of the textile waste, realizing a large-scale resource utilization of the textile waste.

[0006] To achieve the above object, the present disclosure provides the following technical solutions:

[0007] The present disclosure provides a textile waste regenerated flooring, comprising a layer being an extruded sheet, the extruded sheet being prepared from a mixture consisting of 30-50 parts by weight of a textile waste fiber, 30-50 parts by weight of an inorganic filler, and 10-30 parts by weight of polyethylene, wherein the textile waste fiber is prepared by opening a textile waste and granulating sequentially, wherein the polyethylene has a molecular weight of 40,000-300,000, the inorganic filler is calcium carbonate and has a particle size of 200-400 mesh, and wherein the textile waste regenerated flooring is prepared by a method comprising mixing the textile waste fiber, the inorganic filler and the polyethylene to obtain the mixture; and subjecting the mixture to a melt extrusion, a shaping, and a lamination, to obtain the textile waste regenerated flooring.

[0008] In some embodiments, the mixture consists of 40 parts by weight of the textile waste fiber, 40 parts by weight of the inorganic filler, and 20 parts by weight of the polyethylene.

[0009] The polyethylene has a number-average molecular weight of 40,000-300,000, which is determined by gel permeation chromatography.

[0010] In some embodiments, the melt extrusion is conducted at a temperature of 120-160 °C.

[0011] In the present disclosure, there is no limitation to the source of the waste textile through accurately controlling dosages of waste textile, inorganic filler and polyethylene, and a large-scale resource utilization of the textile waste could be achieved. Moreover, the textile waste regenerated flooring could meet specific needs in appearance, and has a better decoration by controlling the type and color of materials; meanwhile, the textile waste regenerated flooring provided by the present disclosure has advantages of high strength, acoustic insulation and absorption, thermal insulation, and no pollution.

[0012] In the present disclosure, the method for preparing the textile waste regenerated flooring is simple and fast to complete, with fewer steps, favoring the realization of industrial production.BRIEF DESCRIPTION OF THE DRAWINGS
