什么是聚酯纖維

聚(ju)(ju)(ju)酯(zhi)(zhi)纖(xian)(xian)(xian)(xian)維(wei)(wei)也被稱為PET纖(xian)(xian)(xian)(xian)維(wei)(wei)，是(shi)聚(ju)(ju)(ju)酯(zhi)(zhi)材料制作而成的(de)(de)(de)。聚(ju)(ju)(ju)酯(zhi)(zhi)是(shi)由多元醇和多元酸(suan)縮聚(ju)(ju)(ju)而得的(de)(de)(de)聚(ju)(ju)(ju)合物，其中(zhong)的(de)(de)(de)部分PET，再通過水下切(qie)粒就會形(xing)成聚(ju)(ju)(ju)酯(zhi)(zhi)纖(xian)(xian)(xian)(xian)維(wei)(wei)。纖(xian)(xian)(xian)(xian)維(wei)(wei)級聚(ju)(ju)(ju)酯(zhi)(zhi)切(qie)片用(yong)于制造滌(di)綸短纖(xian)(xian)(xian)(xian)維(wei)(wei)和滌(di)綸長絲，是(shi)供給(gei)滌(di)綸纖(xian)(xian)(xian)(xian)維(wei)(wei)企業加工纖(xian)(xian)(xian)(xian)維(wei)(wei)及相關產品的(de)(de)(de)原(yuan)料，滌(di)綸作為化(hua)(hua)纖(xian)(xian)(xian)(xian)中(zhong)產量最(zui)大的(de)(de)(de)品種，占(zhan)據著化(hua)(hua)纖(xian)(xian)(xian)(xian)行業近80%的(de)(de)(de)市場(chang)(chang)份(fen)額，因此聚(ju)(ju)(ju)酯(zhi)(zhi)系列的(de)(de)(de)市場(chang)(chang)變(bian)化(hua)(hua)和發展趨勢是(shi)化(hua)(hua)纖(xian)(xian)(xian)(xian)行業關注的(de)(de)(de)重(zhong)(zhong)點(dian)。同時，聚(ju)(ju)(ju)酯(zhi)(zhi)還(huan)有瓶類、薄膜等用(yong)途，廣泛(fan)應用(yong)于包(bao)裝業、電(dian)子電(dian)器、醫療衛生、建筑、汽車等領(ling)域(yu)，其中(zhong)包(bao)裝是(shi)聚(ju)(ju)(ju)酯(zhi)(zhi)最(zui)大的(de)(de)(de)非纖(xian)(xian)(xian)(xian)應用(yong)市場(chang)(chang)，同時也是(shi)PET增長最(zui)快(kuai)的(de)(de)(de)領(ling)域(yu)，可以說聚(ju)(ju)(ju)酯(zhi)(zhi)切(qie)片是(shi)連接石化(hua)(hua)產品和多個行業產品的(de)(de)(de)一(yi)個重(zhong)(zhong)要中(zhong)間(jian)產品。

聚酯纖維的性能及用途

1、性能

滌綸(lun)的比(bi)重為(wei)1.38，熔(rong)點為(wei)255～260℃，在205℃時開始粘結，安全熨(yun)燙溫度為(wei)135℃。吸(xi)濕度很(hen)低，僅為(wei)0.4%。長絲的斷(duan)裂強(qiang)度為(wei)4.5～5.5克(ke)/旦(dan)，短纖(xian)維為(wei)3.5～5.5克(ke)/旦(dan)。長絲的斷(duan)裂伸長率為(wei)15～25%，短纖(xian)維為(wei)25～40%。高(gao)強(qiang)型纖(xian)維強(qiang)度可達7～8克(ke)/旦(dan)，伸長為(wei)7.5～12.5%。滌綸(lun)有優良(liang)(liang)的耐(nai)皺性(xing)、彈性(xing)和(he)尺寸穩定性(xing)，有良(liang)(liang)好(hao)的電絕緣性(xing)能，耐(nai)日(ri)光，耐(nai)摩擦，不霉不蛀，有較(jiao)好(hao)的耐(nai)化(hua)學(xue)試劑性(xing)能，能耐(nai)弱酸(suan)及弱堿。在室溫下，有一(yi)定的耐(nai)稀強(qiang)酸(suan)的能力，耐(nai)強(qiang)堿性(xing)較(jiao)差。滌綸(lun)的染色(se)(se)性(xing)能較(jiao)差，一(yi)般須在高(gao)溫或有載體存在的條件下用分散性(xing)染料染色(se)(se)。

2、用途
