选用服装厂常用的6种雪纺织物,测定其基本参数,采用正交试验方法,分析线迹密度、机针、缝纫线3种缝纫参数对缝口强度的影响及雪纺织物性能与缝口强度的相关性。试验结果表明:对于较薄的雪纺织物,缝口破坏形式为纱线滑脱,线迹密度的影响最为显著,缝口强度与线迹密度成负相关;对于较厚的雪纺织物,缝口破坏形式为缝纫线断裂,缝纫线的影响最为显著,缝口强度与线迹密度、缝纫线粗细成正相关;而机针对缝口强度的影响最小。 相似文献

针织面料具有非常好的服用性能,其与机织面料一起搭配使用,会收到意想不到的效果。但是针织面料的可缝性不如机织物,二者在搭配缝制时会产生一些弊病,尤其是缝口质量。现就针织面料与机织同类面料拼接,对不同针距密度、压脚压力、缝纫线张力、送布牙差动对缝合布表面特征的影响,以及拉伸率、缝口断裂强度等性能方面的影响进行分析和研究,得出最佳缝纫组合方案。 相似文献

为探究针织内衣织物接触冷暖感与织物结构及力学性能的关系,采用KES-F7精密瞬间热物性测试仪测试14种针织内衣织物的最大瞬态热流量。从织物密度、织物厚度等结构参数以及织物相关力学性能等方面分析其影响因素。结果表明:织物结构越紧密,织物中静止空气含量越低,皮肤与织物接触冷感强烈;织物表面越光滑,皮肤与织物接触面积越大,接触冷感强烈;织物厚度越大,皮肤与织物接触暖感强烈。织物的结构参数影响织物中静止空气含量,从而对织物接触冷暖感产生影响。由织物最大瞬态热流量与织物力学性能参数相关性分析可知,减小织物与皮肤的接触面积,提高织物的蓬松性,有利于增强织物的接触暖感。 相似文献

在分析玄武岩纤维纯纺纱线力学性能及耐酸碱性能的基础上,采用32.5 tex×2玄武岩纤维低捻度纯纺合股纱,在Stoll公司的CMS530HP型全自动电脑横机上编织4种弯纱深度及组织结构不同的纬编织物,并对织物的热防护性能进行测试与分析。结果表明,玄武岩纤维纯纺纱线经酸或碱溶液处理4 h后,断裂强力和断裂伸长率的保持率大于60%;玄武岩纤维脆性大、柔性小,编织速度和牵拉力宜偏低设置;纬编织物克质量越大,热防护性能越好;织物组织相同时,弯纱深度越大,织物热防护性能越差。该研究为研发具有热防护功能的高性能纬编织物提供技术参考。 相似文献

In the present study, the formation of tension seam pucker is considered in more details in order to compute the thread compression load in terms of sewing thread tension. To this end, the stitch formation in the fabric is simplified. The exerted thread compression force on the fabric in each stitch is calculated according to the thread tension, its mechanical properties and the cycles that the sewing thread suffers before shaping the stitch. In addition, the fabrics properties that are effective on the seam puckering are measured and their relation with the applied load on the fabrics is investigated. This process is carried out for 12 various fabrics which can be classified into three groups according to the application in the clothing. Outcomes indicated that it is possible to compute the compression force on the fabric in each stitch in every sewing tension level that is useful to predict the seam puckering formation in fabrics with known mechanical properties. The results of this research help to analyse the compression load on the fabric based on sewing thread tension. 相似文献

The distributions of the tangential and radial stresses acting on the yam of a fabric during sewing as the sewing needle is inserted into the fabric have been discussed by means of the mechanical principles of elasticity. The influence on the needle penetration force caused by the shape of the cross section and the profile curve at the needle point has also been investigated. It is suggested that five parameters. i.e., the mechanical properties of the textile material k, the variation ratio y' of the needle radius, the contacting arc length θ. the frictional coefficient μ and the sewing machine speed v are the main factors that determine the penetration force of the sewing needle. The variation ratio y', or the slope at any point of the needle profile, is the most important factor for needle design. Depending on the analysis of the forces acting on the needle surface, an optimum profile curve has been obtained. If this curve is used as a new sewing needle profile, the penetration force can possibly be reduced by up to 20%. 相似文献

本文首先调查分析不同类型缝份部位整体弯曲性能的变化,然后着重研究在不同接缝位置、不同缝型和不同缝份宽度条件下有缝织物的悬垂性能变化及其原因。结果显示:缝份部位的抗弯长度和抗弯刚度与原织物相比有明显增加;有缝织物的悬垂系数、平均半径、硬挺系数等指标均大于无缝织物;一般缝份宽度增加,悬垂系数有稍微增大趋势;接缝的位置对悬垂性的影响与织物经纬向性能有关;抗弯长度大的缝型一般比抗弯长度小的缝型对悬垂系数影响大;试样边缘缝份会导致圆周方向的抗弯性能提高,从而使悬垂系数增加。该研究将对缝制后面料及服装造型评价及模拟具有一定的实践指导意义。 相似文献

缝制作为服装生产中的重要工艺过程,缝纫质量控制难度大,受到许多因素的影响,必须充分了解面料性能,合理选择缝纫设备,优化配置缝纫工艺才能达到最优的缝制质量。目前在服装加工中,缝制加工工艺的确定主要是依靠经验,其结果易受到环境和选定者主观态度等因素的影响,具有很大的模糊性。针对不同服装针织面料进行相关测试和试验并根据面料的物理测试结果对面料进行分类,可运用DPS数理统计软件和正交设计助手对缝口拉伸回复率试验结果、缝口缩皱试验结果、缝口接缝强力试验结果进行分析,以Y1面料为例,研究各类针织面料缝制工艺参数优化组合的确定方法,可以为服装企业针对不同针织面料快速选择合理的缝制工艺参数提供方法和依据。 相似文献

This paper reports a determination of a sewing quality index in order to assist the industry in providing quality clothing before production. The particularity of this work lies in the fact that it encompasses various sewing quality parameters (efficiency, slippage, and puckering) into a single overall quality index. Moreover, a program was investigated, to determine the quality index, so that the manufacturer has only to enter the available data. In fact, by entering the input parameters which are blend composition, seam direction, fabric mass, stitch density, and seam thread linear density, an overall quality index will be given and the seam quality as well as the defect sources will be displayed. To reach this aim, regression models were determined to predict seam quality. In this work, 18 denim fabrics were sewn with two commercial sewing threads. Their influences, ranked according to the seam quality, were also determined. The seam efficiency was calculated by determining both the seam and the fabric's tensile strength. The seam slippage was determined by calculating the difference between the elongation at the break of the seam and the elongation at the break of the fabric. Seam puckering was determined by measuring both the fabric and seam’s thickness. 相似文献
