Embodiment Construction

[0011] An environmentally friendly and easily degradable non-woven fabric, comprising the following steps: 3-5 parts by weight of zinc borate, 20-30 parts by weight of jute, 40-50 parts by weight of short polylactic acid fibers, 5-10 parts by weight of bamboo fiber powder and 3-5 parts by weight of 5 parts by weight of zeolite powder are successively unpacked, mixed and loosened to remove dust and impurities, and then pass through a carding machine and an air-laid machine to obtain a mesh; 3-6 parts by weight of adhesive, 2-3 parts by weight of water-repellent Mixing agent and 80 to 90 parts by weight of water to obtain an impregnating liquid; immersing the mesh in the impregnating liquid to form a film to obtain a prefabricated film; drying and shaping the prefabricated film at a drying temperature of 150° C. to 160°C, drying time 1-2 minutes, setting temperature 120°C-130°C, setting time 3 minutes; calendering finishing, rolled into storage; the film is calendered by a cold r...

Abstract

The invention discloses an environment-friendly and easily degradable non woven. A method comprises the following steps of: unpacking 3-5 parts by weight of zinc borate, 20-30 parts by weight of jute, 40-50 parts by weight of polylactic acid short fibers, 5-10 parts by weight of bamboo fiber powder and 3-5 parts by weight of zeolite powder in sequence, mixing and opening the materials, then dedusting and cleaning the materials and then treating the materials by a carding machine and an air laid machine, thus obtaining meshes; mixing 3-6 parts by weight of adhesive, 2-3 parts by weight of water repellent and 80-90 parts by weight of water, thus obtaining an impregnation liquid; immersing the meshes in the impregnation liquid to be bonded to form films, thus obtaining pre-films; drying the pre-films at a temperature of 150-160 DEG C for 1-2 minutes and setting the pre-films at a temperature of 120-130 DEG C for 3 minutes; carrying out calendering finish and rolling and warehousing; and calendering the films by a cold calendar and then cutting, rolling and warehousing the films. The preparation method is simple in process. The prepared plant fiber non woven is degradable.

Description

technical field [0001] The invention relates to the technical field of nonwoven materials, in particular to an environmentally friendly and easily degradable nonwoven fabric. Background technique [0002] Non-woven fabric (English name: Non Woven), also known as non-woven fabric, is composed of directional or random fibers. Exciting, colorful, cheap, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. At present, the global public hazard "environmental pollution" is becoming more and more serious. For example, the application of plastic mulch film as a modern agricultural technology has a great effect on increasing crop production, increasing farmers' income, and promoting the development of agricultural production. However, plasti...
