The effects of spinning conditions and fiber size on two-layered spun yarns were investigated by a method for evaluating yarn structure quantitatively. The yarn structure analysis method is based on HPD-analysis. In this analysis, HPD (Helical Path Difference) is defined as the accumulation of difference between the mean helical paths of two fiber assemblies consisting of the two-layered yarn. The yarn structure change is caused by the variation of mutual dynamic balance of two fiber assemblies. Then it can be analyzed by investigating the mutual relation between two helical paths that represent these two fiber assemblies. It is proved experimentally that the doubling of two fleeces gives no particular influence on the yarn structure formation in spinning process. Our results therefore may be useful and valuable in controlling the yarn structure.

The textile design is composed of the patterns on the surface of the fabric. But as the viewing distanceincreases, the design tends to be recognized as a large rough design. First, the visually effective distances are measured for design elements which have subjectively been evaluated. The visually effective distance expresses the precieved differences between designs in terms of visibility at different viewing distances. Next, low-pass filtered images of the textile designs are correlated with the original images in terms of the measurement of the textile identification distance.The spatial frequency components are shown as a visual feature of textile design related to visibility and also expressed by the visually effective distance.

Several agents named Warmth-retaining agents are mixed in the coated layers on the polyester fabrics.The aluminum-powder or the copper-powder which retains the warmth with reflection shows greater warmth-retention when the coated layer is on the outer side of the clothes than on the inner side.On the other hand, carbon-powder or the oxidized iron-powder shows greater warmth-retention when the coated layer is on the inner side of theclothes than on the outer side.Electron micrographs showed clearly the various structures in the coated layers when the warmth-retaining agents are mixed in the resin.There are the multilayers, porous layers, and/or airly layers made with the warmth-retaining agents, air, and the resin.Basing on these structure, roles of the warmth-retaining agents are discussed.

In order to evaluate interlaced yarns on an on-line real time system, diameters of interlaced raw yarns were measured by means of an optical sensor, and effects of feed ratio, supplied air pressure and yarn speed on various evaluation quantities were quantitatively clarified. Results obtained are as follows. The number of tangles measured with the sensor agrees excellently with that by eye when yarns are well interlaced. The relation between the distance between tangling parts and its relative frequency is discussed, and the frequency obtained with the sensor almost agrees with that by eye. Yams with a large number of tangles have not only a small standard deviation of the distance between tangling parts but also a large interlacing effect index, which represents both the number of tangles and the distinction between opening and tangling parts. Therefore, it can be said that interlaced yarns are qualitatively evaluated from only the number of tangles.
