棉针织物新型氧漂工艺研究
|
摘要
棉针织物常规氧漂工艺存在助剂使用量大、生产成本高、氧漂不均匀等问题。氧漂均匀剂QM由多种表面活性剂和无机盐复配而成,具有精练、螯合、碱及双氧水稳定剂等多种功效,文中使用氧漂均匀剂QM对棉针织物进行氧漂,探讨最佳工艺处方,并与常规氧漂进一步做染色试验,并测试处理后织物染色色差。结果表明,当氧漂均匀剂QM用量为3.00%时,织物能够得到更好的白度和毛效,同时提高白度和毛效的均匀性;通过氧均匀剂QM氧漂后染湖蓝色,其色差555分色结果明显优于传统氧漂后染色,且验布无色渍;氧漂均匀剂QM氧漂工艺不需要使用NaOH、渗透剂、分散剂,生产1吨布节省成本152元,具有较高的经济效益。
The conventional oxygen bleaching technology of cotton knitwear has problems such as large amount of auxiliary agent application, high production cost and uneven oxygen bleaching effect. Oxygen bleaching homogenizer QM is made up of various surfactants and inorganic salts, which has many functions such as refining, chelation,alkali, hydrogen peroxide and stabilizer. In this paper, it used uniform oxygen bleaching agent QM to bleach cotton, and discussed optimum prescription. And then the fabric was dyed after the oxygen bleaching treatment,which was compared with the dyeing effect of the conventional oxygen bleaching process. And the dyeing color difference of the fabric was also tested. The results show that the whiteness and capillarity effect can be improved by using 3.00% oxygen bleaching homogenizer QM, and the uniformity of the whiteness and capillarity effect can be improved, too. Lake blue was dyed by oxygen bleaching homogenizer QM, and the color difference 555 was obviously better than the traditional oxygen bleaching dyeing. Oxygen bleaching uniformity agent QM oxygen bleaching process does not require the use of NaOH, penetrants and dispersants, which can save RMB152 per ton of fabric compared to conventional oxygen bleaching, and the economic benefit is higher.
