Description
Technical field
The present invention relates to biomass polyester fibre technology field, specifically, is a kind of highly dense knitted shirt fabric and preparation method thereof.
Background technology
Along with the development of global economy, the demand of oil is growing, and petroleum resources successively decrease day by day, and contradiction between oil supply and demand increasingly sharpens, and the war of contention oil grows in intensity.The whole world is all in that living resources inexhaustible on the earth make great efforts to study, exploration in order to utilize.Utilize reproducible biomass resource, development bio-based chemical industry, the petroleum replacing chemical products are the only ways that solve resource and energy crisis, are the important channels of sustainable development.Therefore, exploitation can reduce or the raw material of petroleum replacing are very important research directions.
The polyester dacron fiber itself has excellent performance and cheap price, it is the fiber species the most representative in China's three large synthetic fiber, that output is maximum, and its main raw material ethylene glycol originally derives from the petroleum industry product, therefore, angle from the industry sustainable development, essential new material and the new technology of seeking energy petroleum replacing ethyl glycol makes PET industry can effectively evade the price risk of petrochemical material continuous rise.
Polyethylene terephthalate (PET) has in fields such as packaging material, film, engineering plastics, clothes very widely to be used, because the raw material of producing PET all derives from the processed goods of oil, not only bring environmental problem, and along with the rise of oil price, the pressure of China's chemical fibre industry is increasing.Therefore, a kind of living beings raw material of oil that replace of exploitation seem most important.Because bio-based 2,5-furans diacid can make by catalytic cracking reaction behind the biomass ferments such as maize straw, and bio-based 2, the chemical constitution of 5-furans diacid and the structure of terephthalic acid (TPA) are closely similar, therefore can be with bio-based 2,5-furans two acid substitution terephthalic acid (TPA)s carry out polymerisation.In addition, E.I.Du Pont Company is by fermenting to corn, through biology and chemical process, make 1, ammediol has been developed the polytrimethylene terephthalate (PTT) that contains the 36wt% that has an appointment and derive from living beings, and successful application is to fields such as clothes, film, engineering plastics.
Ethylene glycol is the important source material of synthetic PET, and at present industrial oxirane direct hydration method or the ethene synthetic methods of adopting are produced more.Production cost is high, and consumes a large amount of raw material and the energy, generates a lot of accessory substances.China is large agricultural country, and abundant living resources are arranged.Macromolecular polysaccharide in the renewable resources such as the plant residues such as agricultural crop straw, husk, corncob is converted into the derivatives such as fermentable sugars, fermentation organic acid and biological multielement alcohol with chemical degradation or biodegradable method.Take these tunnings as starting monomer, synthetic living beings macromolecular material can be saved more petroleum resources to greatest extent fully, promotes the development of recycling economy.
Exploitation and the application of PDT bio-based polyester---with bio-based ethylene glycol directly as the raw material of polyester three autoclave apparatus for continuous polycondensation at 1000 ton/years, carry out esterification with the p-phthalic acid, again polycondensation, make than the existing more excellent novel polyphenyl dioctyl phthalate component of the manying binary alcohol esters PDT polyester of polyester, and the processed and applied of successful confession downstream POY, FDY, DTY is in woven and knit fabric, and excellent spinning properties and dyeability result from that to contain mass fraction in the bio-based ethylene glycol be 2.5% multicomponent binary alcohols such as propylene glycol, butanediol and pentanediol.Petroleum law PET polyester 99.5%EG, (petroleum law)+PTA → PET, (Polyethylene Terephthalate) polyphenyl dioctyl phthalate second diester petroleum law PTT polyester, (CORTERRA:Brand by SHELL) PDO, (petroleum law)+PTA → PET, (Polytrimethylene Terephthalate) polyphenyl dioctyl phthalate propylene diester bioanalysis PTT polyester, (Sorona: Brand by Du Pont) PDO, (by corn with bioanalysis)+PTA → PTT, (Poly trimethylene Terephthalate) polyphenyl dioctyl phthalate propylene diester
Socorna is the trade name of day a kind of novel PDT (bio-based PET) fiber, yarn and the textiles in sea.
