         polyester fiber is Domestic amount most large, product types most more textile type fiber. 但我国 new type polyester PTT(terephthalic acid 1,3-丙二 alcohol ester)切 sheet/slice long 期依赖 Imported, its polymerization key/critical technology by DuPont and housing/shell company 垄断. Shenghong group has company, clothing/apparel 学院, in 鲈科技 development corporation has company and other formed PTT and function 化PET polymerization and its composite/compounding fiber made key/critical technology and industry 化, more function polyester large amount industry technology, raw materials innovation belt/tape product innovation, is polyester industry development new 模式, achieve high quality textile product from polymer to product Domestic 化, obtain 2015 year 国家科学 technology 进步二 and other 奖.

         Shenghong corporation engineering 师梅锋告诉记者, project 依托国家科技支撑 plan project high series polyester fiber made and application technology, more year 艰苦攻关, most achieve core technology 4项 breakthrough, not only 填补 国 inner in new type polyester and composite/compounding function fiber 方面 空白, make in field/area to world front 列.

        首先, project breakthrough PTT and modified PTT(MDPTT) polymerization, material and recycling and other formed sleeve/set technology, independent R&D titanium -锡 composite/compounding catalytic agent and new type stabilizer, design process/workflow ester 化, low temperature polycondensation process/workflow, achieve high energy saving flexible copolymer. project R&D crystallization pelletizing technology can energy saving 27%~35%, ring poly understanding poly, separation and recycling technology not only reduce material consumption, also achieve propylene aldehyde and alcohol 无害化处理.

         its 次, project large amount more function PET(MFPET) and large amount polymerization, melt key/critical technology, 创建 以 has machine (P22)/无 machine (ATO) anti-static agent 复配, has machine (UV234)/无 machine (TiO2) UV resistant agent 协效, wet mono and agent composite/compounding more function technology, independent design 出旋流匀化 anti poly equipment, electrical remove plant/unit, ester and di 鼠笼搅拌 polycondensation and high light low temperature melt system, formed made MFPET.

         again 次, project design specialized filament key/critical plant/unit, development 出MDPTT, MFPET and high degree 差PTT(MDPTT)/MFPET fiber formed formed sleeve/set technology, made wet, elastic property, anti-static, UV resistant and other more function combined polyester fiber.

         most rear, project formed R&D hot wet property polyester combined formed and its fiber manufacturing formed sleeve/set technology, solution function property powder ultra- dispersion, ester 化, polycondensation speed rate, separation structure and versus for separation quality control and other issues, development more function polyester polymerization and melt key/critical technology, production different function combined hot wet property polyester long filament, short fiber and its material.

        据梅锋 introduction, project formed already in Shenghong group formed industry 化, rear formed strip/profile tool has independent Knowledge 产权 3 10,000 tons / year PTT连续 polymerization production 线, 25 10,000 tons / year full light more function polyester polymerization and melt production and 5 10,000 tons / year MDPTT/MEPET elastic property can series more function polyester fiber production 线. project production MDPTT, MEPET and its composite/compounding fiber output/production volume and market has rate inner 首位, polyester fiber 差别化 rate ultra- 80%, is enterprise new increase sales 收入近100 100 million yuan, product export day and other and 区.

        3 10,000 tons / year PTT/MDPTT polymerization plant/unit construction, make Shenghong formed is DuPont, housing/shell rear 第三 拥 has PTT polymerization has technology enterprise;25 10,000 tons / year large amount more function MFPET melt polyester fiber production plant/unit construction achieve more function polyester toward fine 旦, ultra- fine fiber, 异形截面 fiber field/area 拓展, make Shenghong formed is full most large melt more function long filament manufacturing 商;5 10,000 tons / year elastic property series polyester fiber production construction, achieve independent combined formed new type function property polyester is raw materials made safety, 舒适, more function fiber, material and clothing/apparel, formed independent Knowledge 产权.

        业 inner expert is, project formed R&D and industry 化, promote polyester technology and product rise grade 换代, meet/satisfy for high new type material demand, is enterprise belt/tape new growth 点, more improve/increase 我国化纤面 material market competition force.

         through project production different function combined hot wet property polyester long filament, short fiber and its material, its output/production volume and market has rate 均居国 inner 首位.
