本文介绍了γ射线在棉针织物加工中的应用。对棉织物的环保前处理（煮漂）条件进行了系统的研究。在该实验中使用的织物包括160 gsm的棉针织单面平针织物结构。将纯棉针织坯布浸泡在不同质量浓度（0 ~ 30 g/L）的过氧化氢溶液中10 min，然后用Co-60 γ射线以5 kGy/h的剂量率对试样进行辐照，辐照剂量为5-20 kGy。以织物的吸水率、白度指数、失重率、顶破强力、顶破伸长率和上染率作为煮漂性能的指标。新工艺生产的产品白度和吸水率均达到要求，适合于浅色染色。当辐照总剂量为5 kGy时，用10 g/LH_2O_2溶液处理样品，可获得最佳结果。吸水率和WI值分别为2.4s和39.43，并且获得82.2%的上染率，对于该选项具有203.20kPa的顶破强度。但较高剂量的辐射会降低织物的顶破强力。然而，辐照样品表现出良好的可染性，表明与Bezaktive Red S-3B和Novacron Yellow ST-3R活性染料具有优异的匀染性。(C)2014爱思唯尔有限公司版权所有。
This study attempts to introduce the exploitation of gamma radiation for the processing of cotton knitted fabric. A systematic investigation into the situations suitable for eco-friendly preparation (scouring and bleaching) of cotton fabric was carried out. Fabric used in this experiment includes cotton knitted single jersey structure of 160 gsm. The grey cotton knitted fabric was immersed in different (0 - 30 g/L) amount of hydrogen peroxide solution for 10 min. Subsequently, the samples were irradiated under Co-60 gamma radiation of absorbed dose (5-20 kGy) at a dose rate 5 kGy/h. Water absorbency, whiteness index (WI), weight loss, bursting strength, elongation at burst and dye uptake were taken as the measure of extent of scouring and bleaching performance of the intended fabric. The new technology yielded product with acceptable whiteness and water absorbency which is suitable for pale shade dyeing. The optimum results were achieved for the sample irradiated at a total dose 5 kGy treated with 10 g/L H2O2 solution. The water absorbency and WI value were 2.4s and 39.43, respectively, as well as 82.2% dye exhaustion was obtained having the bursting strength 203.20 kPa for this option. But higher dose of radiation was found responsible for lowering the bursting strength of the fabric. However, the irradiated samples demonstrated the good dye-ability indicating the excellent level dyeing with Bezaktive Red S-3B and Novacron Yellow ST-3R reactive dyes. (C) 2014 Elsevier Ltd.
