为了提高设计师设计全成形毛衫组织结构的能力,以典型羊毛衫组织为例,借助岛精四针床全成形电脑横机,研究了全成形毛衫编织技术、工艺优势及全成形对组织结构设计的影响,探讨其在全成形上的工艺实现。研究表明:四针床编织技术有不同于二针床的独特性,它最适合编织空气层,不能编织四平组织,设计全成形毛衫组织时必须考虑图案的连续性和可编织性。 相似文献

为更好地实现全成形毛衫局部三维立体成形,以四针床电脑横机及SDS-ONE APPEX 3设计系统为依托,重点对局部编织在全成形毛衫上的应用进行研究。将局部编织工艺按照编织方法分为常规局部编织和按比例局部编织,探讨局部编织在肩斜、领部、下摆、挂肩以及平袖山部位的应用。结果表明:常规局部编织可形成光滑平整的肩部斜线形状、前后领深弧线、不规则下摆;按比例局部编织是全成形毛衫独有的编织方式,主要应用于挂肩和平袖山编织,可用于维持筒状编织平衡和实现袖子、大身的连接,形成存在一定高度差的筒状编织物;采用局部编织工艺可提高全成形毛衫的舒适性和美观性,也为毛衫款式开发提供思路,满足当代消费者的个性化需求。 相似文献

This paper proposes a modelling of the dynamic behaviour of textile fabrics based on a new formulation of deformable models. Deformable models such as those that were introduced by Terzopoulos in 1987 for modelling and simulation of deformable objects in computer graphics are reformulated to simulate textile woven fabrics. This investigation tends to produce simulations of textile fabrics showing the dynamic aspect of their behaviour while remaining faithful to the physical reality of material. The developed model takes into account several mechanical and physical parameters of textile fabrics. Numerical resolution of partial differential equations controlling the behaviour of textile fabrics is made by using the finite element method. Several simulations are carried out and compared with the experimental results. A drape‐meter test is simulated and the results are strongly correlated with those obtained in experiments. 相似文献

This paper aims to analyse the effect of coating, fabric layers and structural parameters on the impact resistance behaviour of warp knitted spacer fabrics used for protective clothing. For this purpose, six warp knitted spacer fabrics were produced by varying thickness and mesh structure and were coated with a silicone substrate. A drop-weight impact tester was used to determine the impact resistance characteristics of the samples. The results indicate that, the impact resistance properties of warp knitted spacer fabrics can be improved considerably by coating as reducing approximately 10 kN of the peak transmitted force. Also, the structural parameters such as fabric thickness and mesh structure have significant effects on impact resistance behaviour of the samples. The fabrics with higher thickness and smaller size mesh on the outer layers have better impact resistance properties. Additionally, the lamination of spacer fabrics can effectively improve the impact resistance characteristics of the spacer fabrics. The warp knitted spacer fabrics can be used as an energy absorbing material for body protection by varying their structural parameters, fabric lamination and/or by coating. 相似文献

The heat transport properties observed in nanostructured materials such as aerogel-treated nonwoven fabrics are promoting revolutionary breakthroughs as thermal insulators. This article is focused on the thermal transport characteristics of nonwoven fabrics treated with aerogel for potential uses in thermal protective applications. Highly efficient aerogel thermal blankets are now considered a viable option in applications such as clothing, building, and pipelines. A variety of fiber and fabric structures or finishing parameters influence the functional properties of nonwoven materials. In order to assess the thermal properties of aerogel-treated nonwoven fabrics, the KES Thermolabo II and NT-H1 (plate/fabric/plate method for thermal conductivity, qmax cool/warm feeling, and thermal insulation) was used. Fabrics of higher thicknesses show lower heat conductance and therefore higher thermal insulation properties. It has been found that thermal insulation is also related to the weight and compressional properties of the fabric. To make an insulating material effective, it should have low compression set and high resiliency to make the still air to be entrapped into the fibrous material. 相似文献
