通过实验的方法,对不同紧密系数的玻璃纤维针织物的尺寸特性进行了研究,实验表明,玻璃纤维纬平针织物的线圈长度主要由弯纱深度决定;织物的横密与紧密系数呈线性相关,玻璃纤维针织物的线圈形态系数随织物的紧密系数增加而显著减小,同时,玻璃纤维针织物的厚度仅与纱线的线密度线性相关,与织物的弯纱深度关系不显著。 相似文献

为研究织物结构对织物保暖性能的影响,选取了四平组织、罗纹空气层组织、1+1罗纹组织、畦编组织和半畦编组织5种常用的毛衫组织结构,采用相同的原料编织一系列弯纱深度的试样并进行线圈长度、织物厚度、透气性和保暖性能测试。结果表明: 四平组织织物最轻薄;畦编组织织物保暖性最好且透气性最佳;织物的保暖性受厚度和透气性的双重影响,对于单一线圈结构织物,在一定的弯纱深度范围内,厚度对保暖性的影响起主导作用,随着弯纱深度的增加透气性对保暖性的影响占主导作用;保暖轻薄系数与弯纱深度之间为二次多项式关系。 相似文献

Sorona纤维具有良好的生态环保和可持续发展性,与羊毛混纺,可明显改善常规毛/涤面料的弹性和抗皱性能,也可用作高档针织毛衫的原料,以赋予服装舒适的弹性,并改善服装的手感及体感舒适性。文章以Sorona/毛混纺纱线为原料,织造了3种不同结构的针织物,并通过调节横机上成圈三角的弯纱深度,编织不同紧密度的针织物,系统地分析了弯纱深度对各织物透气性和保暖性能的影响关系,对Sorona/毛混纺针织毛衫的生产及质量控制起到一定的指导作用。研究结果表明:横机弯纱深度对Sorona/毛混纺针织物的透气性、保暖性影响明显,随着弯纱深度的增大,织物的透气性增强,而保暖性能呈现出先减弱后增强的变化趋势。 相似文献

为研究纤维性能对针织物尺寸特性的影响,在横机上编织了5种弯纱深度的平针、1+1罗纹、满针罗纹和米拉诺组织玄武岩纤维针织物。通过对松弛后织物的尺寸参数的测试,分析玄武岩纤维针织物纵向、横向以及面积尺寸随时间的变化规律,并对织物密度进行回归分析。结果表明,玄武岩纤维织物密度与线圈长度倒数呈正线性相关的关系。比较了玄武岩纤维针织物与毛/腈针织物的线圈形态,由于玄武岩纤维具有较高的抗弯刚度,其针织物的线圈形态较为扁平。通过对玄武岩纤维针织物尺寸特性的研究,可实现织前对织物尺寸的预测。 相似文献

为分析线圈类型对织物形态的影响,在STOLL公司生产的3.5.2机号的HP530型电脑横机上编织一系列成圈、浮线、集圈和移圈结构单元组合的织物,利用超景深显微镜拍摄并测量线圈结构参数,总结出不同结构对织物形态的影响规律。从力学角度研究织物线圈变形的根本原因得出,由于织物中线圈类型的改变,打破原有的受力平衡,造成纱线张力的改变,在张力作用下纱线在相邻线圈之间发生转移,从而导致织物形态改变。将织物中的线圈简化为质点,线圈的变形规律被转化为质点系统的位移规律,该研究为利用质点系统进行横编织物的计算机模拟仿真提供理论研究基础。 相似文献

Fabric surface unevenness and defects are usually created by yarn irregularity and defects in weaving process. These unevenness and irregularities appear on fabric and affect various fabric properties. In order to investigate weft yarn mass irregularities on fabric surface unevenness and defects, various plain fabric samples were prepared in which they differ only in weft yarn mass irregularity. One of the effective factors on fabric surface unevenness is yarn protrusion in fabric structure. Yarn protrusion in fabric structure is influenced by yarn’s physical and mechanical properties and fabric structural characteristics. In this work, relationship between mass irregularities of weft yarn and fabric surface unevenness was investigated using angular power spectrum curve, a measure of yarn protrusion in fabric structures. The results showed a high significant correlation between these two parameters. 相似文献

The aim of this study was to investigate the effect of cotton fiber and yarn characteristics on the color variation of woven fabrics dyed with vat dyes. A fabric length of 31?m was woven so that each meter of the fabric comprised weft yarns of slightly different cotton fiber or yarn characteristics as compared to the other. The woven fabric was pretreated and dyed with vat dyes using industrial-scale, pad-dry-chemical-pad-steam process. After dyeing it was found that the fabric containing weft yarns made from cotton with higher reflectance (Rd) values gave poor color strength as compared to that of lower Rd values. Fabric comprising combed weft yarns showed better color depth (K/S) values as compared to that comprising carded weft yarns made from the same raw cotton. Furthermore, the fabric comprising finer- or lower-twist weft yarns gave higher color depth as compared to that with coarser or higher-twist weft yarns. It was concluded that slight variations in the cotton or yarn characteristics in the weft yarns could result in significant shade variations in the vat-dyed fabric. 相似文献

为探讨经编导电织物弹性与传感性能的关系,将镀银基锦纶纱线作为导电纱线分别与氨纶包覆纱线和氨纶裸丝在特里科经编机上交织,制备了具有不同弹性的3种经编导电织物。测试了3种织物在一定拉伸范围内的应力大小与电阻变化,并根据实验数据计算出弹性性能和静态评价指标,得出弹性与传感性能的关系。结果表明:弹性导电织物的电阻随应变呈线性变化,原料越粗则电阻变化的速度越快;弹性模量随着织物弹力的增大而减小,弹性伸长与织物弹力的大小成正相关;在中小应变范围内,弹性模量越低、弹性伸长越大的导电织物传感性能越优。 相似文献

Effects of abrasion on surface roughness properties together with appearance of woven wool fabrics have been investigated. The effects of weft yarn count, weft yarn density, and weave pattern on fabric surface roughness after abrasion were researched. Surface roughness values of control fabric (not abraded) and abraded fabrics after four different abrasion cycles were discussed according to different fabric constructional parameters. It was observed that the greatest decreases in surface roughness values after abrasion were observed in loose fabric structures which had the highest initial fabric surface roughness values (coarse yarn, low yarn density, and low yarn intersection). The results showed that change of roughness properties of wool fabric surfaces after abrasion depends on the initial surface roughness values and on the amount of contact area of fabrics based on the fabric constructional parameters. 相似文献
