紫羊绒无磷脱色工艺研究

以紫羊绒为原料,利用无磷双氧水稳定剂作为含磷稳定剂的替代物,对紫羊绒进行脱色。通过探讨稳定剂种类、稳定剂用量等单因素的影响,并选出4个主要因素硫酸亚铁用量、双氧水用量、氧化漂白pH值和柠檬酸钠用量进行正交试验,以脱色紫羊绒白度提高量和单纤维强力下降率为主要测试指标,优化紫羊绒无磷脱色工艺。结果表明,紫羊绒无磷脱色工艺:硫酸亚铁用量4.5 g/L,双氧水用量70.4 mL/L,氧化脱色pH值为9.5,柠檬酸钠用量16.9 g/L,预处理时间2.0 h,浴比1∶13;采用该工艺处理紫羊绒纤维的白度可提高33.26%,纤维强力下降率0.35%,且可生化降解性好,BOD5/COD(铬法)=2.74。

Determination of cashmere and wool contents in textile by near infrared spectroscopy北大核心

A quantitative analysis model was established to determine the contents of cashmere and wool in textile by near infrared spectroscopy (NIRS). 101 calibration samples were mixed by weighing and measured by NIRS, which were combined to establish the calibration model by partial least squares (PLS) method. The correlation coefficient between the predictive result and true value was 0.99, and the root mean standard error of prediction was 2. 8% . The results demonstrated that NIRS could be a rapid and nondestructive technique for quantitative analysis of cashmere and wool. However, extensive sample collections were suggested in the future work to set up a representative database and to establish a mathematical model with better stabilization, precision and dependability.     

精梳棉竹大豆蛋白羊绒混纺针织纱生产实践

为开发精梳棉、竹纤维、大豆蛋白纤维、羊绒混纺针织用纱,对大豆蛋白纤维进行了预处理,采用了4种原料分别制条,在并条工序进行混和的工艺流程.通过用1根大豆蛋白纤维条、1根羊绒条和4根竹纤维条先进行预并,再用5根精梳棉条和3根预并条进行三道混并的工艺,使混纺比达到了70:20:5:5的设计要求.经测试,所开发的14.5tex针织用纱成纱质量达到了优等品的技术要求.

长绒棉棕色棉绵羊绒混纺纱的生产

为优化长绒棉、棕色棉与绵羊绒混纺纱的纺纱工艺,根据绵羊绒纤维的特点,生产中为保证绵羊绒在梳棉机顺利成网,并较精确地控制各成分的比例,采用三种混和的方法;为了提高绵羊绒可纺性,应对其进行预开松,改善纤维整齐度,排除部分死毛、杂质、短绒.通过采取上述措施,生产的长绒棉/棕色棉/绵羊绒50/30/20 14.6 tex纱各项指标均达到用户要求.
