织物的膜理论   总被引:2,自引:0,他引:2  
为了对织物膜结构和服装进行虚拟模拟,例如膜结构的张紧和褶皱以及服装的悬垂和屈曲,建立了编织物的膜理论.编织物的细观编织结构被引入了膜理论,织物的经线和纬线被选为曲线坐标轴,未变形的纱线作为Lagrangian坐标轴,变了形的纱线作为Eulerian坐标轴.在变形中考虑经线和纱线之间夹角.该理论被用于织物膜的张紧分析.数值结果表明,当应变e12达0.06时,由于纱线夹角的改变导致的应力增加占总应力的25%左右.  相似文献

The term "softness" is loosely used to describe the physical as well as sensory attributes of fabric and other textiles, and several psychophysicai evaluation methods as well as its predicting equations exist. However, the information for physiological mechanism of fabric softness is lack. To explain the blomechauical and the potential neurophysiologicai phecnomenon for exploring fabric softness, accompanying to the procedures in manual exploration for softness and the anatomical multllayor structures of human finer, a contact finite dement (FE) model between finger and fabric is made to conduct an active contact analysis. In present FE model, the effect of surface friction index, compression modulus, Poisson's ratio of fabric on softness dlscrimination is Investigated. The interests are in the contributlons of these fabric property variables to contact area, Interracial friction shear stress and contact pressure distributions, which arc significant cognitive variables or stimulus parameters in peripheral neural levels. The mechanistic data for fabric specimens indicates that the basis for the perception of softness of flexible and bulk fabric is likely on the spatial variation of pressure on the skin (or, equivalently the skin displacement and its derivatives) resulting from surface friction phenomenon and compression property of fabric. In present model, however, the effect of Poisson's ratio on the total force exerted by fingertip is not significant statistically. Therefore, compression modulus of fabric is, not the only underlying physical variable accounting for peripheral neural response, and also the surface friction phenomenon plays an important role in feeltouch softness of fabric, i.e. the compressibility and surface properties of fabric arc the necessary physical variables involved for the haptic rendering of its softness.  相似文献

To find out the reason of resulting in the crease recovery of a fabric and provide theoretical guidance for designing a new material with good creasing-recovery property,the relationship between the creasing-recovery force and the crease-recovery angle of a woven fabric was investigated by self-setup experimental device.The results show that the crease-recovery angle of a woven fabric is correlated with the creasing-recovery force of the fabric in a linear relation.Furthermore,it is found that the internal stress is the principal force of affecting the creasing-recovery property of a woven fabric.In addition,the relationship between the tensile property of a woven fabric and the creasing-recovery property of the fabric has also been investigated,showing that the lower relaxation velocity of tensile stress of a fabric is,the better creasing-recovery property of the fabric has.  相似文献

Fabric-skin adhesion was objectively described by the indices of the maximum adhesion force F_(max) , the maximum separation distance L_(max) ,and adhesion work W as well as the adhesion force-separation distance curve. Firstly,gray correlation analysis method was adopted to investigate the correlation levels between adhesion indices,and secondly the relative importance of fabric structural parameters to fabric-skin adhesion,as well as the correlation levels between skin adhesion, water absorption, and wicking properties of the fabric. The results prove that W exhibits clear correlations with both F_(max) and L_(max) , yet the relevance between F_(max) and L_(max) is weak. Fabric adhesion indices are most associated with fabric mass and least with fabric thickness,whereas fabric wicking and water absorption present closest correlation with fabric thickness. Therefore, it is concluded that the relevance between fabric wicking, water absorption, and skin-adhesion properties are rather comprehensive than straight.  相似文献

The tensile property of bi-axial warp knitted fabrics is tested and compared with that of the plain weave fabric. The results show that there are obvious differences between the tensile property of a bi-axial warp knitted fabric and that of a plain weave fabric. The former can give fuller play to the property of a high modulus yarn than the latter. The tensile strength of a bi-axial warp knitted fabric is linear with the number of yarns in the direction of force.  相似文献

根据针刺复合织物结构,分析其在拉伸过程中的内部应力场,说明拉伸应力应变预测计算的困难。织物拉伸变形时,随着应变逐渐增大,织物应力应变本构关系逐渐失去线弹性特点,而表现为纺织材料固有的粘弹性质,使织物拉伸变形具有物理非线性特点。讨论了具有这种特点的织物拉伸应力应变分析计算的有限元方法,并对该有限元方法的算法作出说明。计算结果与实验结果有较好的一致性。  相似文献
