针织服装结构设计方法研究 总被引:4,自引:0,他引:4
由针织面料弹性变化及方向性提出建立人体静态净体样板,通过对日本文化原型胸省、肩省处理和松度调整,得到的图形称为“针织服装原型”,对照人体静态净体尺寸进行了合理性分析,提出了运用针织服装原型进行结构设计的方法。并分别就合体、宽松型服装的结构设计和紧身型服装的结构设计作了应用举例。 相似文献

通过问卷调查,得到人体跑步时下肢各部分肌肉疲劳程度。采用锦氨包芯纱和锦纶在Santoni SM8 TOP2无缝内衣机上编织12种不同结构针织面料,采用定伸长拉伸测试面料拉伸性能。选用拉伸至相同拉伸率时所需拉伸力较大的几种面料制作紧身跑步裤,介绍紧身跑步裤结构设计和尺寸设计,对紧身跑步裤穿着效果进行主观测评。结果表明,人体跑步时下肢腓肠肌内侧、臀大肌、股直肌3个部位最易疲劳,不同组织的针织面料产生服装压不同,基于跑步时下肢疲劳状态设计的紧身跑步裤合理,能在保证人体穿着舒适的前提下达到减缓疲劳的目的。该研究为紧身服装的服装压分配、尺寸设计及制作提供参考。 相似文献

Saanen goats were used to determine the effect of the alteration of the intramammary Na to K ratio on milk secretion. Udders were infused via the teat with an isosmotic solution that was high in Na or K to increase or decrease, respectively, the intramammary Na to K ratio. Control glands received an isosmotic sucrose solution. To ensure that the results were not confounded by a decrease in milk secretion as a result of enhanced permeability of mammary tight junctions, the latter was monitored throughout the experiments. An increase in the Na to K ratio caused a significant transient reduction in milk secretion. Therefore, an increase in Na and a decrease in K in milk, commonly observed as a result of the leakiness of tight junctions, may at least partially explain the reduction in milk secretion when the permeability of tight junctions was increased. These experiments further showed that the adverse effects on secretion were not due to a high intracellular concentration per se but were related to a change in the Na to K ratio because a reduction in the ratio also lowered milk secretion. These data support the evidence for activity of Na(+)-K(+)-ATPase in the basolateral secretory cell membranes and passive movement of these ions across the apical cell membranes. 相似文献

By testing fabric extraction properties, the PhabrOmeter Fabric Evaluation System offers the potential for routine objective evaluation of fabric handle. In this paper, a series of simple linear models has been developed using fabric extraction curve data for a series of lightweight next-to-skin knitted wool fabrics. These models predict eight fabric handle characteristics: overall handle, rough–smooth, hard–soft, loose–tight, heavy–light, hairy–clean, warm–cool and greasy–dry. The models were validated using an independent set of fabrics. The prediction precision of the models is significantly better than the precision of an experienced individual assessor. 相似文献

During ripening of mangoes, color change kinetics were studied with Alphonso, Banganapalli, and Neelam varieties. The internal and external color change was recorded using CIE-Lab color coordinates. L, a, b, and total color difference (ΔE) values were measured for internal pulp and external peel during the ripening period. Four kinetic models viz. zero order, first order, fractional conversion, and logistic models were used for modeling using MATLAB. Among the explored models, the logistic model was found to be more suitable to predict the changes in all external color coordinates in all the three varieties. Internal color coordinates of different varieties were exhibited contrasting behavior. So different kinetic models were proposed to predict the internal color change for different variety. The fractional conversion model was found to be not suitable in color change kinetics during ripening of mango. 相似文献

冷冻储存对鸡蛋理化性质及微观结构的影响 总被引:1,自引:0,他引:1
本文通过测定pH、粘度、回弹高度和结构的变化,表征了置于-20 ℃下,储存不同的时间的新鲜鸡蛋的全蛋、蛋清、蛋黄、熟蛋及熟蛋黄的性质变化。实验结果表明:在-20 ℃下,新鲜鸡蛋随储存时间的增加,煮熟的全蛋回弹高度变小,熟蛋黄的回弹高度增大,从5 h到36 h,熟蛋黄的回弹高度从提高了2倍到4倍;蛋黄、蛋清和全蛋的pH值和粘度均发生了明显的变化,且pH的变化在储存10 h后更为显著;储存10 h的蛋清、蛋黄结构开始发生变化,蛋黄在冷冻24 h后质地变得较为平滑、紧密,可清楚表现为形成凝胶,到冷冻36 h后达到不可逆的变化。因此:在-20 ℃下,储存10 h,新鲜鸡蛋的品质已经由合格品下降为不合格的次品。 相似文献

为探究跑步运动时女性下肢肌肉、皮肤形变与服装运动功能性之间的关系,通过生物力学仿真系统对周期跑步运动人体下肢肌肉的肌纤维主动力进行分析,选取肌纤维主动力均值明显的肌肉,将其峰值所在的时间帧对应的动作作为关键帧动作,并使用手持式三维扫描仪对关键帧动作的下肢皮肤进行扫描;综合左右半身的皮肤形变情况,分析不同动作的下肢皮肤形变数据差异性,同时对比动静态人体模型展开的细分曲面。研究发现:臀围到中腿围区域的体后侧、臀围至大腿围区域的体前侧的变化幅度最大,膝关节附近区域变化幅度较大,其它区域变化不明显。本文研究可为相关裤装结构设计与研究提供参考。 相似文献
