中文摘要 | 為了克服反應性染料染棉纖維的弊因,本實驗分別用了DCPEAT和CPVT兩種反應型的架橋劑對棉纖維進行改質。棉纖維首先用這兩種反應型的架橋劑做二種不同的實驗方法進行前處理,之後用改質過的CI Reactive Red 120染料進行染色,發現在不使用助劑的狀況下使用反應型染料染棉纖維,也能獲得很高的染色固著率。 |
英文摘要 | In order to overcome the disadvantages of reactive dyeings of cellulose substrates, the concept of reversing the conventional system by incorporating the nucleophilic group in the dye and the reactive group containing the electron deficient carbon atom in the fibres is explored with compound A: 2,4-dichloro-6-(2'-pyridinoethylamino)-s-triazine chloride (DCPEAT) and compound B: 2-chloro-4-(2'-pyridinoethylamino)-6-(4"-vinylsulphonylanilino)-s-triazine chloride(CPVT). Cotton was pre-treated either by an exhaustion method or a pad-batch method. The dyeing was carried out using the bisaminoalkyl derivative of C.I. Reactive Red 120. The results indicated that the modified cellulose dyeing process is successful, giving high uptake in the absence of salt and a high degree of dye-fibre covalent bonding. |
