纤维棉

Generally,it is considered that cotton fibre is a column and its surface is smooth.The surface structure of Xinjiang long fine hair cotton is researched by using electronic microscope scanning (S-570 Japan).The result shows that the cotton fibre is not a column,but is spiral.The fibre of only 15%does not twist.The surface of the fibre is not smooth,and there are burrs on it.These characteristics would be another important factor effecting the stickability of cotton.

一般认为，棉纤维呈圆柱状，纤维表面是光滑的，笔者以新疆长绒棉为研究对象，用日立S-57日扫描电镜，研究了棉纤维的表面结构，结果表明，棉纤维并非呈圆柱状，自然状态下呈螺旋形，象氨基酸那样，根据概率估计，没有扭曲的约占15%，棉纤维表面并不光滑，有毛刺，这种结构特性是影响棉花粘着性的又一重要因素。

Based on a survey of the mechanism for reactive dyes containing β-hy-droxy-ethyl sulfonyl sulfuric ester on the cellulosic fibre, and the structures of non-ionic nature of disperse dyes , a new range of reactive disperse dyes for polyester cotton blends is proposed.

本文综合分析了含β-羟乙基碸硫酸酯基活性染料的染棉机理和聚酯纤维用非离子型分散染料的结构特点，提出了一类用于涤棉混纺织物的含β-羟乙基碸硫酸酯基活性分散染料。

It is suitable for dealing with coloration of loose stock, materials such as cotton, wool terylen and velour cashmere etc.

本机型适合各种类型散纤维的染色，如羊绒、羊毛、棉、毛、丝、腈纶等及其混纺产品。

In this paper, 52 transgenic insect-resistant cotton varieties of Gossypium hirsutum from China and abroad, have been used to investigate fiber quality traits, construct cluster dengrogram. Based on the SSR and AFLP analysis, we analysised the diversity and constructed the fingerprinting of the cultivars.

本研究选取国内外陆地棉转基因抗虫棉品种52份，对其纤维品质进行测定研究，建立聚类图；并利用SSR和AFLP分子标记建立52份供试材料的指纹图谱，从表型和分子水平综合分析其遗传多样性。

RT-PCR analysis showed that GhMADS1 gene expressed in petals, stamens, ovules and fibers, but not in roots, stems, leaves, bracts and sepals. The strongest expression of GhMADS1 gene was detected in petals. But in floral buds of a cotton homeotic mutant (CHV1), whose floral organs are all converted to bract leaf-like organs, the transcript of GhMADS1 gene was not detected.

RT-PCR分析显示，该基因在陆地棉的花瓣、雄蕊、胚珠和纤维中表达，特别是在花瓣中表达量最高，而在根、茎、叶等营养器官和棉花同源异型突变体CHV1（所有花器官均变为苞叶状叶性器官）的变异花蕾中不表达。

Centrifugal glass wool is a silk-like material made by fiberization in the TEL process and spraying of thermosetting resin. By further deep processing of thermal setting, this material can be made into series of multi-purpose huari products.

离心玻璃棉是将熔融状态的玻璃用离心喷吹法工艺进行纤维化并喷涂热固性树脂制成的丝状材料，再经过热固化深加工处理，可制成具有多种用途的系列产品。

In the accessions of upland cotton with high fiber quality, we found four cSNPs with nonsynonymous substitute, which may have phenotype effect.

对陆地棉高强纤维品系间的SNPs位点进行了统计，发现有四个cSNPs位点中存在非同义突变，可能具有表型效应。

This thin web is gathered into a soft mass and pulled into a ropelike strand of fibers about1.9～2.5 cm in diameter, called sliver.

薄薄的纤维层汇聚成一个柔软的棉束并被拉伸成条子，其直径为1.9-2.5厘米，通常被称之为棉条。

Firstly, the yarns were tested on USTER to get several important parameters with which we would determine the quality of the yarns. Then, on the basis of test results and PTT characteristics, we put forward some constructive advise on how to improve the quality of PTT spun yarn.

首先我们在USTER上检验成纱质量，得到条干均匀度、棉结、细节等指标，并针对PTT纤维的特点，提出了纺纱过程的改进方法。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
