机织间隔织物柱纱高度的确定

机织间隔织物的厚度由柱纱的高度决定.为了确定影响柱纱高度的因素,从几何结构角度出发,定义了影响机织间隔织物柱纱形态的5个结构参数,并建立了结构参数间的几何关系.通过将柱纱高度计算值同实测值的比较,发现计算值与实测值吻合得较好,证明所建立的柱纱结构参数间几何关系能够很好地反映实际情况.     

阻燃双层机织面料的设计及其性能研究

以3/1右斜纹为表组织,3/1左斜纹为里组织,设计了一种"下接上"接结双层组织。在此基础上采用芳纶或芳纶混纺纱作为表经表纬,天然纤维纱线作为里经里纬,设计并织造了两种表层阻燃、里层舒适的阻燃双层机织物试样。通过对试样进行阻燃性能测试,结果表明,两种试样的阻燃性能均达到阻燃要求。通过对试样进行导水性、透湿性和透气性能测试,结果表明,试样二的阻燃性能尽管较试样一稍差,但完全符合服用面料阻燃标准要求,且试样二克重较小,舒适性能明显优于试样一.

Evaluation of Woven Fabrics for Comfort Properties in Children’s Summer Wear

This paper evaluates the comfort properties of eightkinds of woven fabric commonly used for children'ssummer wear in Hong Kong,China.Due to the expan-sion of children's wear market and the quality require-ment for parents,objective and subjective measurementsare the main methods used to evaluate the chosen fabricsfor garment deslgners and consumers as reference. Objective measurement was carried out through ex-periments by means of the Kawabata Evaluation Systemfor Fabrics(KES-F).Experimental tests on fabrics in-clude compression,surface,bending,air permeability,thermal and tensile.Subjective measurement was con-ducted by a market research on consumers' opinions onfabrics for children's summer wear in the form of ques-tionnaire survey.These two ways of measurement onfabrics were analyzed and compared. It was found that Fabric Sample 6 which is com-posed of polyester and cotton fibre has the best perfor-mance in terms of its comfort properties.Besides,Sam-ple 4 composes of rayon and cotton fibre also ha     

Research on Tearing Property of Reinforced Plastic Film with Bi - axial Warp Knitted Fabric Skeleton

The specification of laid-in and warp yams,thedensity of fabric and the specification of groundyam are of great importance when the bi-axialwarp knitted fabric being knitted.In this paper,the tearing property of the reinforced plastic filmwith bi-axial warp knitted fabric skeleton istested and analyzed.The resuits show thatamong the three factors,the specification of laid-in and warp yam has the greatest influence onthe tearing strength of the reinforced plastic film,while the rest of them has secondary and lesseffect respectively,and there is exponential re-lation between the tearing strength of the rein-forced plastic film and the number of yams in thedirection of force.

针对现有织物疵点图像分割方法对光照不均匀敏感的问题,提出了一种基于局部熵和变异度的织物疵点图像分割方法。首先对织物图像进行局部熵和变异度计算,提取疵点的类边缘和区域信息;然后基于人工神经网络脉冲耦合（PCNN ）的区域生长法分割织物疵点图像。通过对T ILDA数据库中的疵点图像和基于线阵CCD在线检测的织物疵点图像进行测试,并与已有的相关方法进行对比实验和评价。结果表明,该方法不仅能有效地抑制光照不均匀和复杂背景干扰的影响,而且分割质量有了明显改进。     

Three-Dimension Parametric Simulation of Knitted Fabric Based on the Twisted Loop Model

To enhance the realistic simulation effect of knitted fabric, a new three-dimension （3D） twisted loop model was proposed. This model was constructed by using Non-uniform Rational B-Spline （NURBS） surface. The control points of this surface were generated through rotating the cross-section along the center path of yarn. The cross-section of yarn was generated based on the two-level hexagonal ~lose packing model. Both of the center path and the cross-section were fitted by NURBS. With this twisted loop model, 3D parametric simulation of knitted fabric was realized in 3DS MAX by utilizing MAXScript and analyzing the relationships between structure parameters （including the wale-spacing, the course-spacing, the yarn diameter, .and the fabric thickness） and geometric model. The simulation of knitted fabric has 3D realistic twist effect dearly. Furthermore, the structure parameters and the twist parameters of fabric can be modified interactively.
