Description
Technical Field
The invention relates to the technical field of non-woven fabrics, in particular to a bio-based polyester non-woven fabric and a preparation method thereof.
Background
Nonwoven fabrics, also known as nonwovens, are composed of oriented or random fibers. It is called a cloth because of its appearance and certain properties. The non-woven fabric has no warp and weft, is very convenient to cut and sew, is light in weight and easy to shape, and is popular with hand fans.
Because it is a fabric formed without spinning a woven fabric, it is formed by orienting or randomly arranging textile staple fibers or filaments to form a web structure and then reinforcing them by mechanical, thermal or chemical means.
The fabric is not interwoven and knitted by yarns one by one, but the fibers are directly bonded together by a physical method, so that when a user takes the fabric into the clothes, the user can find that one thread end cannot be drawn out. The non-woven fabric breaks through the traditional spinning principle and has the characteristics of short process flow, high production rate, high yield, low cost, wide application, multiple raw material sources and the like.
Biomass belongs to plant-fixed solar energy, and billions of tons of biomass can be used for producing bio-oil every year in China; millions of tons of polyester garbage are generated in industry and daily life every year, and if the materials are not properly treated, the environment is polluted, and solar energy resources and petroleum resources are seriously wasted. Due to the advantages of abundant biomass resources, strong renewability, environmental improvement, sustainability, and material properties, the development and utilization of biomass resources are of great interest to scientists. The reasonable utilization of biomass energy can keep the carbon balance in nature, is not only beneficial to the development of agriculture, forestry and industry, but also has important significance for inhibiting greenhouse effect and protecting ecological environment.
