纬纱

Based on the hypothesis of rectangle and biconvex section shape of the yarn, and different collocation between the inner warp and outer warp, thickness, section shape of the same structure being considered especially, a model for predicting the elastic property of 2.5-D woven composites was developed. To verify the elastic model, 62 samples of 2.5-D woven composites with 6 various structures were selected and the elastic properties were measured.

基于经纱矩形截面及纬纱双凸透镜截面假设，重点考虑了该结构表层经纱与内部经纱密度的不同及相同机织结构合成不同厚度和纤维束截面的情况，建立了2.5维机织复合材料的弹性性能预测模型。

Secondly, based on the research of the fabric"s contexture characteristic, the author puts forward using the convex shape as yarn"s section, builds the yarns dimensional geometry model and axes equation of warp and weft. Establishes the illumination model which is fit for fabric with illumination theory.

在研究织物组织模拟的基础上，提出以凸透镜形作为纱线截面，建立了相应的纱线空间几何模型和经、纬纱轴线方程；利用光照理论，结合织物的特点，建立了适用于织物的光照模型。

They are made with new process of weft surrounding contiguously and non-middle-suture by the composite sack-making machine.

维纶水溶纱复合包装袋是由复合制袋机工艺技术制成的纬纱连续环绕无中缝的新型包装袋。

It is blended with glass fiber weft, polyester fiber warp, the fabric's elongation, flexibility and abrasion resistance can be improved, heat-resistant is better than cotton belt, it can replace cotton belt that request the stretch long rates and higher abrasion resistance of the winding of the electrical equipment insulation material packed.

一种以聚酯纤维为经纱、玻璃纤维为纬纱的混纺带，织物的伸长率、柔软性和耐磨性都得以提高，耐热性又优于棉布带，可代替棉布带用于对伸长率和耐磨性要求较高的电机电器的缠绕包扎的绝缘材料。111

For each layer-divide symbol appeares regularly in weave diagram, the layer-divide symbol is affirmed first,then the attribute of each yarn and weft is fixed,the weave of each layer is analyzed at last. As to leno fabric, the reverse side of the fabric should be analyzed, tell the crossing warp from normal warp before drafting the looming draft.This paper introduces the method to analyze this kind of complex fabric through above two examples.

对四层织物分析时，找出组织图上有代表性的组织点的属性，因分层符号在组织图上出现时很有规律，可以先确定各层分层符号的位置，进而确定各根经纬纱的属性，分出各层织物，最后分析各层的组织；纱罗织物分析时，应分析织物的反面，先要区分出绞经和地经，然后才能绘出组织图。

In order to interlace warp and weft threads to produce fabric on any type of weaving machine, three operations are necessary

为了在任何类型的织机上将经纱、纬纱交织形成织物，需要三个运动。

Based on the interstices of yams, warp and weft crossed areas are located, and four textures of these areas are obtained by first-order and second-order statistics.

基于纱线间隙和经纬纱交叉区的存在，通过一阶和二阶的统计量可获取4种区域结构特征。

In reality, the shuttle is actually a projectile but the distinctive feature of shuttleless looms that the filling package be exterior to the filling carrier, disqualifies the shuttle loom from consideration.

片梭织机利用一只小片梭携带纬纱穿过梭口，实际上的梭子是片梭，只是由于具有无梭织机纬纱卷装不在载纬器之内的特点，因此不再将其看成有梭织机。

A curve diagram of front-side warp angles of receded wefts relative to frictional coefficient between warp and weft is drawn, and application of the diagram is illustrated.

绘制了回退纬纱前侧经纱角相对于经纬纱间摩擦因数的变化曲线，阐明了曲线图的应用方法。

Since there is no moving package, there can be no normal selvages and it is usual for the projectile always to travel in the same direction when carrying the yarn rather than to reciprocate as in a normal loom.

由于纬纱卷装不运动，也就不能形成常规的布边。通常片梭携带纬纱总是沿一个方向飞行，而不是像有梭织机的梭子那样往复运动。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
