In order to clarify the influence of forms of brassieres on beauty of clothing bust silhouettes, a visual impression of the bust clothing silhouette formed by C70 size brassieres in wearing under clothes was studied. Subjects (female college students) wore twenty-three types of brassieres (limited to C70 size) with different cup shapes under a pullover (of knit material) and their digital images of front, 45°-angled and side views were photographed. Then these images were evaluated by visual sensation of female college students using SD (semantic differential) method. As the result, the concept of “beautiful bust clothing silhouette” was able to be defined by a silhouette that has round, soft, natural and feminine feelings, without wrinkles on clothes and not showing the shape or line of the brassieres through the outer clothing; for example, the unevenness of the lace and seam. And it was found that the ideal shape of the cup is a three quarter cup consisting of seamless or three pieces (3 mai-hagi).

Bust silhouette is one of several very important aesthetic points in the appeal of a women’s body, and it is also well known that an attractive silhouette is influenced by both inner and outer garments. Some odd protrusions can appear in outerwear because of the underlying brassiere, in particular, in spring-into-autumn apparel. As a result, many young Japanese women experience discomfort related to this silhouette. Thus we investigated the relationship between the brassiere and the bust silhouette in knit shirt. The experimental results are as follows: (1) unnatural protrusions result from four causes: the seam, the cup line, the trim lace, and the malformed top part of the brassiere, (2) seamless cup type brassiere makes a contribution to a beautiful bust silhouette, and (3) characteristics of the half-cup type brassiere which produces the worst bust silhouette in knit shirt are the total angle of cup top (BθU + BθL) ≤ 155°, the curved height of the under-cup line (BBL) ≤ 6 mm, and the compression recovery (RC) ≤ 50%.

A versatile method is proposed to predict the shape of a paper model of a three piece brassiere cup. A brassiere cup consists of several cloth and wire parts and the shapes of cloth parts called patterns are determined by repeating creation of a paper cup model, check of its 3D shape, and modification of 2D shapes of patterns. For efficient design of a brassiere cup, prediction of its 3D shape with a simulation is required. The deformed shape of a paper pattern is represented as a single or multiple developable surfaces. So, a model that can represent a pattern both as a single surface and as multiple surfaces is proposed. Which case is selected depends on the magnitude of the potential energy of the pattern in each case. The potential energy of the pattern and geometric constraints imposed on the pattern are formulated based on the model. Minimizing the potential energy under geometric constraints derives the stable shape of the pattern in either case. The validity of the proposed method was verified by comparing predicted and measured 3D shapes of paper models of two types of three piece cups.

In this paper, we propose a convolutional autoencoder with a new structure for unsupervised learning when the purity of the training data is not guaranteed. This autoencoder has two unique features: the target area is reconstructed from the surrounding areas and the L2 loss is predicted simultaneously. The superiority of this model was verified using SEM images of defective nanofibrous materials by calculating the AUC value. The results of our experiments with the training data contaminated by defective data show that the former feature improves the robustness against contamination of the training data and the latter improves the accuracy. Although this approach did not achieve the highest accuracy, it could reduce the cost of annotation for practical use. Furthermore, we applied our method to images of NISHIJIN textiles and found that it worked well for some types of textiles.

In order to reduce the irregularities of sliver made from fine denier fibers, a method of pin-drafting utilizing a moving gill-faller bar was investigated. In the pin-drafting system, both the pin count and the pitch of the gill-faller bar are crucial in the control of staple fibers: the faller bar pitch affects the longitudinal direction of the sliver and the pin count affects it in terms of the width and thickness of the sliver. The effect of fiber control can be estimated by considering the number of fibers in/out of contact with the pins of gill-faller and the size of the group of moving fibers.<BR> The experimental result for fine denier fibers showed that it is necessary to decrease the number of fibers out of contact with the pins of gill-faller and/or the size of the group of moving fibers by controlling the fiber density of the sliver.

The new silk dyeing methods by utilising oxidation and copigmentation of anthocyanins were researched and compared with metal mordanting dyeing. The used colourant was purple sweet potato pigment (PSPP) and its main components were assumed to contain cyanidin and/or peonidin 3-sophoroside-5-glucosides. PSPP dyes silk fabrics purple and the post-treatment changes the colour. The dyeing method were designed two step treatment (post-treatment dyeing). First is dyeing process with PSPP and second is reaction process by using an appropriate material which are Al(III), Cu(II), Fe(II) compound for the metal mordanting dyeing, sodium periodate (NaIO4) for the oxidation dyeing, and polyphenol for the copigmentation dyeing, respectively. The colour of the silk dyed with PSPP is bluish purple for the mordanting dyeing with Al(III) or Cu(II), purplish black for the mordanting dyeing with Fe(II), brown for the oxidation dyeing. The copigmentation dyeing gives deeper purple than the PSPP only dyeing. Their dyeability dependence on the pH of PSPP solution was examined at pH = 2.9 ~ 9.1. The PSPP only dyeing and the copigmentation dyeing gives deeper purple at pH = 4.5 ~ 6.9 and the dyeability of the copigmentation dyeing is higher whole of pH. In the mordanting dyeing with Fe(II), the resulting colour is changed from purplish black to blueish black at pH = 2.9 ~ 7.0, and in the oxidation dyeing that is turned from brown to purplish brown at pH = 2.9 ~ 7.0.

For the restitution behavior between the tennis strings and the ball, the setting unit which can set up the interval length and tension force of the string is produced, and identified the viscoelasticity characteristic of string side and ball by compression, vibration and impact tests experimentally. It was found that the restitution coefficient is increased with the increasing distance of string interval, but reduced with the increasing string tension at the impact velocity of 5.42m/s. The regularity about the viscosity characteristic is not very much obvious. Furthermore, the influences on restitution behavior are discussed by numerical simulation analysis. The simulation results are not only corresponded with the experimental results, but also revealed that string rigidity is great effective on restitution coefficient. The effect of viscoelasticity can be ignored due to its slight influence.

The hair dyeing using green tea extracts containing high amount of catechins in combination with chemical oxidants such as O2, H2O2 and NaIO4 was attempted in order to establish a novel hair dyeing technique without using aromatic amines contained in commercial oxidation dye products. The new hair dyeing technique consists of a twostep colouration system. The first step is treatment of hair with tea extract solution and the second one is oxidation treatment. Three kinds of oxidation methods such as (1) treating hair with basic dyeing solution (pH = 11.5) supplied with large amount of O2 gas (O2 method), (2) treating hair with H2O2 solution (pH = 9.5) (H2O2 method), (3) treating hair with NaIO4 solution (pH = 7) (NaIO4 method) were attempted as the second oxidation treatment. The results show that once dyed hair is discoloured by H2O2 in the oxidation process and white hair is hardly coloured by the method. In contrast, white hair is dyed brown by the O2 or NaIO4 method, and the dyeability increases with increasing temperature of the first tea extract treatment. This may be due to the increase in the amount of dye precursors adsorbed onto hair by heating. Colour fastness of the hair samples dyed by the O2 and NaIO4 method to washing is almost same level as that by the commercial oxidation dyes. The NaIO4 method is more useful than the O2 method because the supply of O2 gas is unnecessary for the NaIO4 one and it uses the neutral solution.

<p>We performed a sensory evaluation of the stiffness of aged hair and damaged hair, and examined the relationship between the obtained sensory evaluation and the bending stiffness distribution curve of the whole hair tress. We used a mixture of gray and black hair as an aged hair tress, and of bleached and permed hair as damaged hair tresses. The results indicated a difference in sensory evaluation of stiffness between the gray and black hair tresses and a difference in the high-rigidity range (85% – 100%) in the bending stiffness distribution curve. A difference was observed in sensory evaluation of stiffness between the different damaged hair tresses. However, chemical treatments resulted in changes in both the low- and high-rigidity regions in the bending stiffness distribution curve. We attempted to find the area of highest correlation between the distribution curve and the sensory evaluation. The distribution curve was divided into several areas and the stiffness average was calculated for each area. We then calculated the correlation coefficient with the sensory evaluation. The results indicated that the area with the top 10% – 15% stiffness of the distribution curve was most closely correlated to the sensory evaluation.</p>

A sun visor has been used only for the purpose of interrupting direct sunshine. Investigation, therefore, has not been made to be on the feeling of touch of the sun visor. In this study, the feeling of touch of sun visor installed in the present automobile was investigated. To clarify the relation between the sense of touch and the mechanical and physical quantity of the sun visor, prototype products of the sun visor of the same shape were made. Surface characteristics and cold feel characteristic of materials were measured by the KES system. In addition, we investigated the relation between the surface property and the sense of touch of various materials. The correlation between favorability and WC, RC, SMD was high on the sun visor prototype. As a result, it was clarified that materials whose surfaces were very smooth and soft were favorable. Those materials consist of leather and moquette. Conversely, the material sensed hard was not favorable. The relation between the mechanical and the physical properties of various materials, and the favorability was able to be approximated by the equation (1).<BR><I>Favorability=2.482+0.02791LC+0.293WC-0.264RC+0.0688MIU-0.0966MMD+0.0253SMD-0.0288qmax</I>(1)

The purpose of this research is to analyze Japanese women's breast shape based on body surface data described by a three-dimensional (3-D) human body shape model with a bi-cubic B-spline structure and to classify them. The data used for analysis were forty-nine 3-D control points selected from the right breast area on the model surface for each of 556 Japanese women aged 19 through 63 years. We examined the covariance matrix of the data using the principal component analysis method after normalization of their 3-D coordinates with the bust width for reducing the size factor. As a result, we obtained four principal components, which described 77% of breast shape. Then Japanese women's breast shape was classified into five classes in the principal component space using the first, second, third and forth-principal component scores. They could cover 92% of Japanese women's breasts. Therefore, we tried to analyze breast shape by clustering in order to classify all the breasts. For the cluster analysis we prepared two kinds of data; (1) principal component scores and (2) the normalized scores (μ=0, σ=1) of (1). With the clustering (1) and (2) we obtained four classes and five classes, respectively. Properties and advantages of the three kinds of classifications were also discussed. The classification of the principal component space is based on standard deviations of principal component scores, and therefore the resultant classes do not have clear boundaries. The classification according to the cluster analysis (1) can reflect the actual distribution of breast shape. In contrast the clustering (2) gives classification reflecting more principal components and tending to generate more classes than the clustering (1).

The hand is one of the important qualities of bath towels. It is interesting to study what physical properties of bath towels correlate to their hand. In this paper, the relationship between the sensory values for the good feel and physical properties of twelve bath towels was studied by means of the principle regression analysis and the correlation analysis. The results are as follows.(1) As a result of principal component analysis, it was found that two principal component “good in touch” and “sturdy and drying property” were chosen to represent the hand of bath towel.(2) The compression feeling was affected by compression properties((To-TM), compression ratio, compression energy, and recovery energy). And the softness feeling was affected by the friction property(MMD), and the warmth by the thermal property(q-max).

To examine the aesthetic properties of pantyhose, an image analysis and wear experiment were carried out. We analyzed both the area ratio of light, medium, and dark lightness areas and the position of three areas in the distribution of lightness difference between legs with and without pantyhose fabric. The data was used to determine what effect these two variables have on the visual appeal of legs in pantyhose. Moreover, we examined the relationship between pantyhose size and women’s leg size on the attractiveness of legs in pantyhose made from single covered yarn with colored polyurethane core yarn. The results showed that, for the enhanced visual appeal of legs in pantyhose, (1) the area ratio and position of three areas in the distribution of lightness difference were very important factors; (2) it was desirable to design and produce the appropriate size of pantyhose for various sized legs in order to enhance their attractiveness.
