Abstract
The invention discloses an environment-friendly composite textile material and a preparation method thereof, and relates to the technical field of textile materials. The invention discloses an environment-friendly composite textile material which is prepared from the following raw materials in parts by weight: 60-80 parts of regenerated PET modified fiber, 10-20 parts of bamboo fiber, 10-20 parts of polylactic acid fiber and a proper amount of fiber impregnating solution; the preparation method comprises the steps of mixing the regenerated PET modified fiber and the bamboo fiber in a wool mixing machine, then placing the mixture in a fiber impregnating solution, taking out the mixture after impregnating for a period of time, airing the mixture, cleaning the mixture, drying the dried mixture, adding the mixture and polylactic acid fiber into a high-speed mixer, and carrying out melt spinning to obtain the fiber. The environment-friendly composite textile material has high strength, excellent toughness, hydrophilicity, air permeability and coloring effect, and good moisture absorption quick-drying property and elasticity; the textile material is made of the regenerated PET fiber and the environment-friendly material, has wide sources and low cost, has good spinning effect, reasonably utilizes the recycled waste resources, reduces environmental pollution, and achieves the purposes of environmental protection and resource consumption reduction.
Description
Technical Field
The invention belongs to the technical field of textile materials, and particularly relates to an environment-friendly composite textile material and a preparation method thereof.
Background
With the rapid development of textile industry in China, the problem of textile materials becomes a bottleneck for preventing the development of the textile materials. With the concept of recycling economy, energy conservation and environmental protection going deep into people's daily life, natural fibers have become a development trend, but the growth rate of natural fibers is far from keeping up with the development rate of textile industry, but textile materials on the market at present are mainly chemical fibers, but the production of chemical fibers presents staged and structural surplus productivity, and a large amount of production can bring about huge environmental pollution, which does not accord with the national conditions of sustainable development of China. In recent years, the development of the polyester industry in China is rapid, the productivity is more than 40% of the world proportion, but the high-efficiency utilization and recovery of polyester are far from those in foreign countries, and particularly the PET recovery and utilization ratio in China is low, and the environment-friendly concept is not compounded, so that the recovery of PET fibers changes waste into valuables, not only accords with the environment-friendly concept, but also plays a very important role in solving the problem of social resource shortage in China.
The source of the regenerated PET fiber raw material mainly comprises waste drinking water and beverage packaging bottles, films, clothes and non-woven fabrics, waste silk, waste blocks and the like generated in the production process of polyester and fiber, wherein the polyester bottle flakes are used as the main source. The regenerated PET fiber has special high molecular structure, low production cost, light weight, high strength, high modulus, no toxicity, high impact strength, acid resistance, oxidation resistance and other advantages, and has wide application range. The regenerated polyester industry in China starts to develop before 40 years, but the industry gradually matures and develops in recent years, the level of development and utilization of the recycled polyester by domestic enterprises is insufficient, scientific research investment liquid for bottle-grade polyester re-spinning technology is insufficient, the quality of the recycled polyester is difficult to meet the requirements of textile fibers, and the recycled polyester is mostly used as a general filling material. The intrinsic viscosity of the existing PET product is generally not more than 0.7dL/g, and then the intrinsic viscosity of the PET product is reduced under the action of heat stress in the preparation process of the PET product, and in the recycling process, slow thermal degradation and hydrolysis can occur when the PET product is contacted with water, acid, alkali, alcohol and the like, so that the molecular weight and the intrinsic viscosity of the polyester are further reduced. Therefore, the regenerated PET fiber must be pretreated to meet the requirements of intrinsic viscosity, molecular weight, crystallinity and the like before spinning. The existing regenerated PET fiber has very low moisture regain, poor moisture absorption and quick drying properties, high fiber strength, small elongation at break, namely high rigidity and small elasticity, and has the defects of similar terylene, namely low moisture content, poor air permeability, poor dyeing property, easy pilling and fuzzing, easy contamination and the like. Therefore, the regenerated PET fiber needs to be modified at present, and an environment-friendly composite textile material which has good spinning property and excellent comprehensive performance and can utilize the regenerated PET fiber is developed.
