Abstract
The invention discloses an easy-to-clean composite textile material and a preparation method thereof, and relates to the technical field of textile materials. The invention discloses an easy-to-clean composite textile material which is prepared from the following raw materials: the PET-modified fiber is regenerated, the hydrophilic polylactic acid fiber is prepared by modifying perfluoro octyl sulfonamide and ethyl orthosilicate, and the finishing liquid is composed of sulfosuccinate, EVA emulsion, diammonium hydrogen phosphate, magnesium aluminum silicate, polyethylene glycol, ethanol and the balance of water; the composite textile material is prepared by mixing the regenerated PET modified fiber and the hydrophilic polylactic acid fiber, then placing the mixture into finishing liquid for dipping, and carrying out melt spinning. The easy-to-clean composite textile material has excellent hydrophilic easy-to-clean property, high strength, excellent toughness and air permeability, wide raw material source, lower cost and good spinning effect, reasonably utilizes recycled waste resources, reduces environmental pollution, and achieves the aims 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 easy-to-clean 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 hindering the development of the textile industry. With the idea of circular economy, energy conservation and environmental protection, natural fibers are gradually deepened into the daily life of people, but the growth speed of the natural fibers is far from the development speed of the textile industry, the textile materials in the market are mainly chemical fibers at present, but the production of the chemical fibers shows that the periodic and structural capacity is excessive, and a large amount of production can bring huge environmental pollution and is not in accordance with the national situation of sustainable development of China. In recent years, the polyester industry in China is developed rapidly, the capacity accounts for more than 40% of the world proportion, but the efficient utilization and recovery of polyester are far from foreign countries, particularly the PET recovery and utilization rate in China is low, and the environmental protection concept is not compounded, so that the recovery and the recycle of PET fibers are changed into valuable, the environmental protection concept is met, and the important effect on solving the problem of shortage of social resources in China is achieved.
The raw material sources of the regenerated PET fiber mainly comprise waste drinking water and beverage packaging bottles, membranes, clothes and non-woven fabrics, waste silk and waste blocks generated in the production process of polyester and fiber, and the polyester bottle sheets are used as the main sources. The regenerated PET fiber has a special high molecular structure, and has the advantages of low production cost, light weight, high strength, high modulus, no toxicity, strong impact strength, acid resistance, oxidation resistance and the like, so that the application field of the regenerated PET fiber is greatly widened. The intrinsic viscosity of the existing PET product is generally not more than 0.7dL/g, the PET product is reduced under the action of thermal stress in the preparation process, and in the recycling process, the PET product is contacted with water, acid, alkali, alcohol and the like to generate slow thermal degradation and hydrolysis, so that the molecular weight and the intrinsic viscosity of the polyester are further reduced.
