style="text-indent:25px">聚對苯二甲酸乙二醇酯PTT纖維:PTT纖維(聚對苯二甲酸丙二脂)是由于20世紀(jì)90年代中期開發(fā)的一種聚酯類新型纖維，南通增強(qiáng)PBT供應(yīng)商。PTT可由1，南通增強(qiáng)PBT供應(yīng)商，3-丙二醇(PDO)和對苯二甲酸二甲酯(DMT)進(jìn)行酯交換后熔融縮聚而成，或由PDO 和對苯二甲酸(PTA)經(jīng)熔融縮聚而成。PTT纖維表面光潔圓滑，是一種半結(jié)晶狀熱塑性聚酯，南通增強(qiáng)PBT供應(yīng)商。它與PBT纖維、PET纖維不同的是在PTT纖維化學(xué)結(jié)構(gòu)中，有一種能量較低的反式-旁式-旁式-反式構(gòu)象并由此呈現(xiàn)出一種明顯的“Z”字形構(gòu)象，同時(shí)在分子鏈結(jié)上PET和PBT上有兩個(gè)亞甲基，而PTT分子鏈鏈接上有三個(gè)亞甲基單元，因此在分子鏈之間會產(chǎn)生“奇碳效應(yīng)”，這種分子結(jié)構(gòu)使得 PTT 纖維具有如同線圈式彈簧一樣的變形能力且回彈性優(yōu)于 PET 和 PBT。作為一種新型合成纖維，聚對苯二甲酸丙二醇酯(PTT)纖維由于本身優(yōu)異的尺寸穩(wěn)定性、抗污性、抗皺性、耐磨性和易染色性，再加上特有的分子鏈結(jié)構(gòu)所帶來的高回彈性，被稱為“21 世紀(jì)新型聚酯纖維”。聚丁烯對苯二甲酸酯可以在無載體的情況下用分散染料進(jìn)行常壓下沸染。南通增強(qiáng)PBT供應(yīng)商</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">聚對苯二甲酸乙二醇酯PET纖維:PET纖維又名聚對苯二甲酸乙二醇酯纖維，在我國常稱為滌綸。目前PET纖維主要采用對苯二甲酸(PTA)和乙二醇(EG)的直接酯化法或?qū)Ρ蕉姿岫柞?(DMT)與乙二醇(EG)的酯交換法來制得。PET纖維的縱截面與PTT纖維相近，在顯微鏡下呈現(xiàn)的橫截面為圓形，縱向粗細(xì)比較均勻，毛羽少，表面光滑。PET纖維的分子式為 [-OC-Ph-COOCH2CH2O-]n，單基是由一個(gè)苯環(huán)、兩個(gè)酯基和兩個(gè)亞甲基構(gòu)成。由于PET分子中存在苯環(huán)，因此在經(jīng)過傳統(tǒng)的熔體紡絲后需要進(jìn)行拉伸，從而使其快速結(jié)晶，這樣可使得制成的纖維取向度和結(jié)晶度較高，由此生產(chǎn)的PET纖維，具有強(qiáng)度高、彈性好、熱定型性能優(yōu)良、耐熱性好、耐酸堿等性能。南通增強(qiáng)PBT供應(yīng)商聚丁烯對苯二甲酸酯耐熱性佳，熱變形溫度可達(dá)180℃以上。</p><div
