The purpose of this study is to develop recyclable fibrous marine materials. To produce polyethylene fibers protected from breeding of seaweed, copper compound, Cu2O and Cu were mixed with polyethylene in the melt spinning process. The melt spinnabity, the mechanical properties of fibers and the elusion properties of copper ion from fiber were examined. Moreover, the chinning test textile made of molded fibers was carried out in the sea. The highest weight fraction of copper compounds to allow a good melt spinnabity was 25% for Cu2O and 30% for Cu, respectively. However, Cu2O was more effective antifouling material against the seaweed compared with Cu. It is due to the larger amount of copper ion eluted.
本研究的目的是开发可循环利用的海洋纤维材料。为了生产不受海藻繁殖的聚乙烯纤维,在熔融纺丝过程中,将铜化合物、Cu2O和Cu与聚乙烯混合。考察了熔体可纺性、纤维力学性能和纤维中铜离子的吸附性能。此外,还在海上进行了模压纤维织物的起皱试验。达到良好熔体可纺性的铜化合物的最高质量分数分别为25%的Cu2O和30%的Cu。与Cu相比,Cu2O对海藻的防污效果更好。这是由于大量的铜离子被洗脱。

A nonwoven aperturing process is.called Stretch Apertured Nonwoven (SAN) technology.One or more layers of nonwoven are processed through a specially patterned, secondary point bonding heated calendar, and then incrementally stretched via ring rolls.The resultant apertured nonwoven retains the original bond points but displays apertures at every secondary bond point.This approach eliminates past barriers toward obtaining nonwovens of high aperture clarity combined with sufficient strength and high softness.
非织造布的开孔工艺是。被称为拉伸孔径非织造布(SAN)技术。一层或多层非织造布是通过一个特殊的图案,第二点粘合加热日历处理,然后通过环辊逐渐拉伸。所得的多孔非织造布保留了原始的粘合点,但在每个次级粘合点上都显示了孔。这种方法消除了过去获得具有足够强度和高柔软度的高孔径清晰度非织造布的障碍。

Effect of Nip Gauge on Irregularities of Sliver in Gill-box 轧条规对轧条箱不平整度的影响

In this research, we discussed the effect of nip gauge on the irregularity of the sliver. Initial experiments were done on an intersecting gill. Various nip gauges were adjusted on the gill-box and the irregularity of the produced slivers were measured. Generally, in the most of the current reports, it was thought that the irregularity of the sliver increases as the nip gauge increases. The results of our experiments on the gill box do not show a significant change in irregularity of wool sliver when the nip gauge was changed. To investigate more detail about this result, we prepared an experimental apparatus with higher variable nip gauge than that of the gill-box. The withdrawing test was done for various distance between the first faller and withdrawer jaws. As a result, we found that the effect of nip gauge on the irregularity of the sliver depends on the fiber length distribution. In case of wool sliver, because of the fiber length distribution, the effect of nip gauge on the sliver irregularity is not significant in a conventional gill-box with its limited nip gauge range.
本文讨论了夹紧规对条子不平整度的影响。初步实验是在交叉鳃上进行的。在绞刀箱上调整各种夹紧量规,测量出条的不均匀度。一般来说,在目前的大多数报告中,人们认为,随着轧厚的增加,条子的不规则性也会增加。我们在刺刀箱上的实验结果表明,当钳距改变时,毛条的不均匀性没有明显变化。为了更详细地研究这一结果,我们制备了一种比鳃盒具有更高可变钳距的实验装置。对第一落料口与抽料口之间的不同距离进行抽料试验。结果表明,夹紧规对条子不匀度的影响与纤维长度分布有关。以毛条为例,由于纤维长度分布的原因,在常规绞箱中,由于绞箱钳距范围有限,钳距对毛条不匀的影响不大。

Water transfer behavior in disposable diapers was investigated by dynamic image processing system and following conclusions were obtained. Water transfer behavior is explained by three characteristic curves such as absorbed water, diffused water, and remained water on the top sheet. New parameters showing diffusion rate in horizontal and perpendicular directions are defined from the characteristic curves of diffused water. Wetting rate and water remaining rate of the top sheet are also defined from the characteristic curves of remained water. These parameters agree well with free water and flow water behavior from diapers and total quality of disposable diapers is evaluated objectively by these parameters.

Recently there has been a demand to spin materials with low spin-ability such as fiber disentangled from waste cloth and special functional fiber in the system of the multi kind and small-quantity production. However modern textile machine systems cannot satisfy it. We have project to develop a spinning system that meets this demand by modeling a human hand spinning system with a spinning wheel and flyer.The purpose of this paper is to examine the principle of a hand spinning system with them from the point of view of control engineering. The rotational speed of the bobbin, position of the right hand, the clamping force of each hand, the thickness of the yarn, etc. were measured in real time. Experimental results revealed that the thickness of the yarn was controlled by the position of the right hand and the twist ratio of the yarn was controlled by the twisting time. Observation and experiment revealed several kinds of human skill such that a slight counter twist action by fingers of the left hand was effective for continuous normal draft operation. Obtained results are useful for the development of the new spinning system mentioned above.
近年来,在多品种、小批量生产的系统中,对从废布中分离出来的纤维和特殊功能纤维等自旋性较低的材料有了纺纱需求。然而,现代纺织机械系统无法满足这一要求。我们有一个项目,开发一个纺纱系统,以满足这一需求,建模人手纺纱系统与纺车和飞。本文的目的是从控制工程的角度来考察用它们组成的手纺纱系统的工作原理。实时测量纱线的转速、右手的位置、每只手的夹紧力、纱线的粗细等。实验结果表明,捻纱的粗细受右手捻纱位置的控制,捻纱的捻度受捻纱时间的控制。观察和实验揭示了几种人类技能,例如左手手指轻微的反扭动作对持续正常的牵伸操作是有效的。所得结果对上述新型纺丝系统的开发具有一定的指导意义。

In this study we investigated the effect of textile structure on mechanical properties and hand values of textile fabrics. Samples used were single cloth in which only textile structure was changed, and having the same yarn and the same density. We investigated correlation between mechanical parameters, hand values and textile structure result by using statistical method. Moreover, we derived estimation equation of mechanical parameters and hand values from the textile structure. It was found that there were effects of textile structure on both mechanical parameters and hand values. Those parameters could be estimated from the textile structure, using multiple regression equation. As a result of principal component analysis, 1 g and 2nd component were obtained which mean fabric softness and surface feeling, respectively. Further, it was found that fabrics were classified into three groups such as hard plain weave, soft satin weave, and other weaves. Correlation between textile structure and those parameters was studied.

In order to evaluate fabric handle of top sheet of disposable diapers objectively, primary hands for the top sheet were selected and defined from the opinions of consumers (mothers) who are using disposable diapers for their children. Four primary hands such as "NAMERAKASA", "SOFUTOSA", "KOSHI" and "FUKURAMI" were defined for the top sheet and they could ex-plain 87% of the descriptions used for hand evaluation. "NAMERAKASA" is considered to be a peculiar primary hand of top sheet of disposable diapers. Objective evaluation equation (DPC M •| 1)of the top sheet using those basic mechanical parameters was developed by stepwise re-gression method with high accuracy and small errors.

In this study, fiber compositions, colors, light reflection characteristics, and light transmission properties for the commercial shoji papers were investigated. The results were as follows. 1) Although the shoji paper predominantly composed of broussonetia-kazinoki (Kozo) contains local aggregations of fibers, the density of the paper was smaller as compared with the shoji paper composed of pulp and/or other fibers. 2) The commercial shoji papers often show a bluish whiteness according to the use of a fluorescent agent. The fastness of the agent to sunlight was not so excellent. 3) The screening effect of shoji paper can be evaluated by measuring its haze value obtained from the transmittance ratio of light. 4) Machinemade shoji papers using rayon, synthetic fibers, binding agents as well as wood pulp are usually produced under hot pressurized conditions. Thus, the surface of the papers tends to become smooth. Accordingly, the machine-made shoji papers reflect light more directly and luster artificially as compared with hand-made shoji papers prepared from broussonetia kazinoki (Kozo).
本文研究了商用shoji纸的纤维组成、颜色、光反射特性和透光性能。结果如下:(1)虽然主要由松木木(Kozo)组成的shoji纸含有纤维的局部聚集,但与由纸浆和/或其他纤维组成的shoji纸相比,该纸的密度较小。2)由于使用了荧光剂,商用shoji纸通常呈现出蓝白色。这种剂的耐晒牢度不是很好。3)通过测量由光的透过比得到的弹纸的雾霾值来评价弹纸的屏蔽效果。4)机器制手纸通常是用人造纤维、合成纤维、粘合剂和木浆在热压条件下生产的。因此,纸张的表面趋于光滑。因此,机器制作的shoji纸比手工制作的broussonetia kazinoki (Kozo)制备的shoji纸更直接地反射光线和人工光泽。

We measured the air flow in clothing microclimate for a standing thermal manikin and human bodies and obtained the following results :(1) The air flow existed at chest, abdomen, back, arms and legs.(2) The difference of the air permeability of clothing did not affect the air flow velocity on the torso but affected it at the arms and legs.(3) The air flow velocity on the torso depended on the condition whether lower sleeve edges and cuffs were open or not, while the air flow velocity at the arms and legs was not affected by the condition of the lower sleeve edges and cuffs.(4) The air flow velocity in clothing microclimate was 0.10 ± 0.05m/s except near the lower sleeve edges and cuffs.
对站立式热人体与人体的服装微气候气流进行了测量,得到以下结果:(1)在胸部、腹部、背部、手臂和腿部均存在气流,(2)服装透气性的差异不影响躯干上的气流速度,但会影响手臂和腿部的气流速度,(3)躯干上的气流速度取决于下袖边和袖口是否打开。(4)服装小气候中,除袖子下缘和袖口附近外,其余部位的空气流速均为0.10±0.05m/s。
