在硅胶涂层中不添加颜料、添加颜料以及添加不同细度的颜料,经过相同的工艺将硅胶涂在织物表面,测试织物的拉伸断裂强力和撕裂强力,分析涂层中不加颜料、添加颜料以及添加不同细度的颜料等条件对织物力学性能的影响。结果表明:硅胶涂层中是否添加颜料对硅胶涂层织物的拉伸断裂强力没有影响,对撕裂强力有影响;不同细度的颜料对硅胶涂层织物的拉伸断裂强力没有影响,对撕裂强力有轻微影响。 相似文献

以硬脂酸、羟乙基乙二胺、1,3-二氯丙醇为原料合成了咪唑啉Gemini型阳离子柔软剂(DIGCS),通过FTIR进行结构表征,并研究应用性能。结果表明,产物具有预期结构,该柔软剂具有较好的耐盐、耐碱、耐硬水稳定性;整理后的织物亲水性与非离子软片整理的织物相当,蓬松度和耐洗性比常规阳离子软片整理的织物要好,能够显著提升织物的撕裂强力,但是会影响织物的拉伸强力和顶破强力。 相似文献

探讨织物组织结构对衬衫面料撕破强力的影响.以纯棉、棉涤混纺、棉涤混纺加少量天丝为原料,织造不同组织结构的织物:平纹、斜纹及纵条纹组织,所有试样均采用同样的液氨免烫后整理工艺.采用冲击摆锤法测定织物的撕破强力,并且从紧度比对撕破强力、织物组织对纯棉试样撕破强力,以及原料对撕破强力的影响三个方面进行分析.结果表明,随着织物的经纬向紧度比增大,织物的纬向撕破强力呈递增趋势;对于常见规格的纯棉织物,平纹组织的经、纬向撕破强力均小于其他组织,尤其是纬向撕破强力较容易出现不合格情况,斜纹组织织物的撕破强力较高,纵条组织织物的撕破强力因组成条纹的各基本组织的配置不同而不同,其撕破强力一般介于平纹和斜纹组织织物之间;在棉涤混纺加入少量天丝时,平纹组织织物的撕破强力会明显提高.产品设计中合理设计织物结构,使经纬向紧度比增大,可以提高纬向的撕破强力. 相似文献

The concept of fabric engineering—the design of fabrics with predetermined physical properties—is used in relation to the structure of woven fabrics, and it is shown from theoretical considerations, with the aid of computer analysis, that a large discrepancy exists between the number of weaves of comparatively small size that can be woven and the number that are actually produced. Experimental results obtained on fabrics woven in accordance with a particular plan indicate that the weave has a very marked effect on both tearing strength and stiffness. The results further suggest that weave modification can provide a means of obtaining very accurate control of the two properties investigated and of their possible combinations, and the same may well be true of other physical properties of fabrics. 相似文献

介绍了角联锁织物的结构特点,采用小样箭杆织机织造了层数为2层、3层到9层的角联锁织物共8块,探讨了角联锁织物的拉伸性能与其结构层数之间的关系。结果表明,随着角联锁织物层数的增加,其断裂伸长率也会随之增加,但到一定层数时,断裂伸长率反而出现降低趋势。 相似文献

为了解PTT/PET三维卷曲复合丝及其不同织物参数对织物拉伸性能的影响,通过改变PTT/PET复合丝比例、捻度、织物组织和纬密4个参数织造了33种织物,测试并分析了这些织物的拉伸性能指标。研究发现:PTT/PET双组分长丝织物拉伸断裂强力较低,而断裂伸长较高,低负荷条件下织物具有高伸长特性;在相同的条件下,随着纬纱PTT/PET含量提高,断裂强力呈下降趋势而断裂伸长相应提高,纬密主要影响织物拉伸断裂强力,对断裂伸长的影响不大,PTT/PET复合丝的捻度对低负荷条件下织物拉伸性能影响明显,因织物组织不同其拉伸性能也存在一定差异。 相似文献

ABSTRACT The fabric tear strength is an important parameter in textile material, ever since it is close to relate to the service of the fabric. Tear strength of the fabrics depends on the flexibility of the yarn in fabric structure. In this research, the tear strength of 11 cotton woven fabrics is analyzed based on the weave parameters such as crossing over firmness factor (CFF), Floating Yarn Factor (FYF), Fabric Firmness Factor (FFF) and weave factor (P1). 相似文献

Three-dimensional (3D) fabrics are the focus of recent developments due to their versatile physical, structural attributes, and application scopes. These fabrics can be manufactured in various architectures which offer a great deal of opportunity to modify the weight, physical and mechanical properties, and cost of the various products. The potential usage of 3D woven fabrics in the ballistic protection applications was the main motivating factor of this research work. Thus, interest has been focused to investigate the structure and properties of 3D woven orthogonal fabrics with aramid fiber and PBO fiber in comparison with 2D fabrics. The investigation of ballistic properties of these fabrics showed that 3D woven fabrics are superior in terms of breaking load and energy absorption as compared to those of 2D woven fabrics. The specific ultimate tensile strength of 3D woven fabric was observed to be lower than 2D fabrics, which may be due to less number of load bearing yarns in the loading direction. The crimp percentages of the load bearing tows in 3D fabric are very less than that of 2D fabrics. Owing to the higher values of work at peak and load at peak, in knife penetration test, it is revealed that 3D fabrics offer better protection than 2D fabrics. 相似文献
