In order to obtain required handle of the fabrics made from wools produced in Xinjiang Province, it is usually necessary to repeat the treatment of the fabrics in wet finish processes. It has been found in practice that the fabric handle can be substantially improved by adding to the fabric a sufficient amount of NaHSO_3 in crabbing, but the strength and wear resistance of fabrics treated in this way are somewhat deteriorated.In this paper, the setting characteristics of Xinjiang wool in comparison with Australian...

In order to obtain required handle of the fabrics made from wools produced in Xinjiang Province, it is usually necessary to repeat the treatment of the fabrics in wet finish processes. It has been found in practice that the fabric handle can be substantially improved by adding to the fabric a sufficient amount of NaHSO_3 in crabbing, but the strength and wear resistance of fabrics treated in this way are somewhat deteriorated.In this paper, the setting characteristics of Xinjiang wool in comparison with Australian wool were investigated. The yarns of these wools were treated with steam, water as well as NaHSO_3 solutions of different concentrations, their lengths, strengths, and also dynamic properties of the treated yarns were measured. The results revealed that the portion of elongation remaining in the Xinjiang wool yarn were greater when the treatments were carried out under stretched conditions, and the net lengths of the Xinjiang wool were shorter when the treatment were carried out without tension. And the setting of the yarns seemed to be more effective when they were treated with NaHSO_3 solutions. The degree of set of the Xinjiang wool appeared to be comparable to that of Australian wool when treated with concentreted NaHSO_3 solutions.

一般说来,新疆细羊毛织物须经过重复湿整工序方能获得所需要的实物质量。实践已经证明,煮呢工序中对织物加入适量的NaHSO_3,可以使织物的手感明显改善,但织物的强度和耐磨性能则有所下降。本文观测了新疆羊毛与对比澳毛的定型特征,新疆毛纱和澳毛纱经过蒸汽、水以及不同浓度的NaHSO_3溶液处理后,测量其长度、强度和动态机械性质。试验结果表示,经过拉紧状态下的处理,新疆毛纱保留较高的伸长率,经过松弛状态处理后,新疆毛纱回缩后的实际长度比澳毛纱为小。NaHSO_3溶液的定型效果较为显著。在较大浓度的NaHSO_3溶液中,新疆羊毛和澳毛的定型效果趋于相等。

对以三乙胺为模板剂的APO-5、SAPO-5型分子筛样品进行了水蒸气处理和酸处理。采用无定形强度卡方法分离样品中结晶相的衍射强度和无定形相的相干散射强度,测定了样品处理前后的结晶度,以及酸处理后样品失重率。实验结果表明,SAPO-5型分子筛的水热稳定性和耐酸性要高于APO-5型分子筛,SAPO-5型分子筛可在低于900℃的水热条件下稳定存在,但只能在弱酸性或中性介质中使用。

The structure stability, surface acidity end catalytic activity for the conversion of metbanol of heterop.tom (Fe) ZSM-5 catalyst treated with steam were studied by TPD,ESR, IR, XRD, Mossbauer spectrum and catalytic conversion of meihanol. It was found that under the influence of steam the ferroatoms in the zeolite framework migrated ep.sily to the surface, leading to the zeolite framework converted to silicalite.The surface acidity of (Fe)ZSM-5 was obviously weaker than that of (ADZSM-5, and the...

The structure stability, surface acidity end catalytic activity for the conversion of metbanol of heterop.tom (Fe) ZSM-5 catalyst treated with steam were studied by TPD,ESR, IR, XRD, Mossbauer spectrum and catalytic conversion of meihanol. It was found that under the influence of steam the ferroatoms in the zeolite framework migrated ep.sily to the surface, leading to the zeolite framework converted to silicalite.The surface acidity of (Fe)ZSM-5 was obviously weaker than that of (ADZSM-5, and the acid sites were mainly of Le.vis acid. With, increasing the steam treatment temperature, the reduction of Bronsted acid was larger tbar that of Lewis acid and the catalytic activity for metbanol conversion decreased.
