ジャーナル フリー強化繊維として炭素繊維とガラス繊維,マトリックスとしてエポキシ樹脂を用いて,二次元ランダム短繊維強化ハイブリッド複合材料を作製し,その力学的性質に及ぼす両繊維の混合割合(ハイブリッド比)の効果及び温度依存性を検討した結果,次のことが明らかとなった。
いずれの温度においても,炭素繊維の割合が減少するにつれて,ヤング係数はほぼ直線的に減少し,引張強度はほぼ一定で,衝撃破壊エネルギはほぼ直線的に増加する。それぞれのハイブリッド比におけるヤング係数,引張強度及び衝撃破壊エネルギは,ハイブリッド比例複合則を用いて推定できる。
いずれのハイブリッド比においても,温度が上昇するにつれて,ヤング係数,引張強度は減少し,衝撃破壊エネルギは増加する。そして,いずれの力学的性質についても,ハイブリッド比-温度の換算性が成立する。抄録全体を表示PDF形式でダウンロード (543K) -

ジャーナル フリーThe flow of polymer melt in a flat die was analyzed theoretically by using a computer simulation and the relationship between the theoretical and experimental results was investigated.
As for the pressure drop in the die, the theoretical results agreed with the experimental ones for different kinds of dies. But with respect to the residence time distribution of polymer melt in the die, especially in case of coat-hunger type die, the theoretical results were slightly different from the experimental ones near the edge of die. As the uniformity of polymer melt depends on die lip clearance, the exact correspondence between theoretical and experimental results could not be obtained. But the theoretical analysis is very useful to evaluate the uniformity of a flat die.
By using the theoretical equations and dimensionless analysis, the scale-up rule considering the pressure distribution, residence time distribution and uniformity index was presented. We can obtain a basic consideration for design of a flat die by means of computer simulation technique, and the experimental results of both smaller flat die and the scale-up rule can be used for efficient design of larger flat die.抄録全体を表示PDF形式でダウンロード (1428K) -

ジャーナル フリーIn an attempt to obtain disulfide-enriched wool (fibers and fabrics), the reaction of wool with a disulfide-containing crosslinking agent, that is, bis (β-isocyanatoethyl) disulfide (BIED), was studied in dimethylformamide. BIED reacted mono-and bifunctionally with wool to form branches and crosslinks, respectively. The crosslinking efficiencies in the percent ratio of the number of the crosslinks (inter-and intrachenic) formed to the total disulfide introduced, which were obtained before and after reduction, ranged from 48% to 66%. The crosslink density of a BIED-treated fiber sample was determined by the method of Arai and Hanyu from Young's modulus in aqueous LiBr/butyl carbitol at 70°C. The crosslink density of the sample determined by the chemical analysis was 1.4 times that of the control wool, while the density determined from the physical method was two times. Supercontraction behavior of BIED-treated wool fibers was compared with that of hexamethylene diisocyanate-treated fibers in either an aqueous solution of NaHSO3, a disulfide reducing agent, or in formamide, a hydrogen bond breaking reagent. Hexamethylene diisocyanatetreated wool fibers did not supercontract in both media, while BIED-treated wool fibers with a low add-on supercontracted in aqueous NaHSO3 but did not in formamide. BIED-treated wool fibers with a higher add-on, however, did not supercontract in aqueous NaHSO3, probably because the excessive introduction of hydrophobic new crosslinks interferes with the penetration of the reducing agent.抄録全体を表示PDF形式でダウンロード (658K) -

ジャーナル フリーt-ブタノール/n-ヘプタン,ギ酸,クロロホルム/メタノールおよびn-プロパノール水溶液で前処理した羊毛繊維への酸性染料の染色速度を検討した。溶剤処理によってみかけの染色速度は次の順序で増大した。
精練羊毛<表面洗浄羊毛<ギ酸処理羊毛=クロロホルム/メタノール処理羊毛<n-プロパノール水溶液処理羊毛。染色速度を相対染着量と√tとの関係で示し,得られた染色速度曲線の比較から,繊維表面に存在する脂質類は染料の浸透に対する障害として働き,繊維内部からの脂質およびタンパク質の抽出は,繊維内部の染料染着を促進することが明らかになった。また,染料の内部層でのみかけの拡散の活性化エネルギーを求めたところ,処理羊毛間でほとんど差異が見られなかった。このことから,それぞれの処理羊毛の繊維内部(特にコルテックス層)における染料の拡散機構はほぼ同じであると推論した。したがって,溶剤処理によるみかけの染色速度の増大は, 1)表面障害効果の減少, 2)細胞膜錯合体の構造変化にともなう繊維内部表面積の増大による染料染着の増大が寄与しているものと考えた。抄録全体を表示PDF形式でダウンロード (423K) -

ジャーナル フリーWe designed a data structure for paper pattern that enables to describe how the fragments or parts of a dress are sewed together and how the dress is put on the body. Such information is required in our system for 3-dimensional CAD for dress. In this system, we input the shape of each fragment, assign the lines to be sewn and mark some lines which are to put at some characteristic position of the body (e. g., waist line). Then the computer divides the fragments into finite elements, establishes the topology of the dress by referring the sewing information, estimates the rough position of each element (i.e., put on the body), calculates the form and distortion of the dress from mechanical characteristics of the cloth and body shape data, and displays the solid view of the result on 3-dimensional graphic display. The fact that our CAD system can simulate the formation of the final shape of the dress, assures that the information given in our paper pattern suffices to indicate how the parts should be assembled and sewn in CAM or automated sewing system. In this paper we describe the data structure of the paper pattern and the automatical division of it into finite elements.
A pattern of a dress usually consists of some pieces of cloth which are to be sewn together, and each piece has rather complicated boundary curves. Even though the lines which will be sewn together have different shapes and lengths, our program generates the points correctly corresponding with each other on every line. Moreover, when the shape of a line is complicated, the pitch of division is automatically reduced so that the line defined by the calculated dividing points well approximates the original line. Then every fragment is divided into a collection of triangles (formally, into a two dimensional simplicial complex).
Our program can divide an arbitrary pattern and can produce well formed triangles, even if there is no additional information for division instructed by the user. Hence, it is suited for the use by those who are not expert with the mechanical analysis by finite element method.抄録全体を表示PDF形式でダウンロード (726K) -

ジャーナル フリーAn attempt has been made to determine the solubility parameter by solubility method of disperse dyes in single and mixed solvents whose solubility parameter values have been known. The solubility parameters of the dyes were also calculated using Hoy's and Small's methods. Furthermore, the relationship between the solubility parameters of the dyes and the amount of saturation adsorption of the dyes on poly (ethylene terephthalate) films was investigated. When the dyes are applied on poly (ethylene terephthalate) films from an aqueous dispersion, the correlation between the solubility parameter values determined by solubility method and the dye adsorptions is closer than that between the values calculated using Hoy's and Small's methods and the dye adsorptions.抄録全体を表示PDF形式でダウンロード (473K) -

ジャーナル フリーThis is a paper concerned with investigating and discussing how the specialists' or consumers' groups perceive the color names and color differences of pile fabrics.
The results obtained are as follows.
(1) Specialists assigned most of color names to the colorimetric ones, but those perceived by consumers did not agree well with the colorimetric ones. A long term training for the specialists in the color recognition results in the exact recognition of the surface colors of pile fabrics and in the proper assignments of the color name. On the other hand, consumers do not realize the correct meanings of the tone adjectives for the lack of experience.
(2) The color names perceived by specialists and consumers by the use of the standard color chips corresponded well to the colorimetric ones.
(3) The correlation coefficient between the color differences perceived by specialists and the colorimetric ones was very high, but the coefficient for the consumers' was low. This fact also indicates as that specialists have established the standard colors for the judgement of color differences by a long term experience on the color differences.抄録全体を表示PDF形式でダウンロード (578K) -

ジャーナル フリー“Wicking” of water was examined with cotton and polyester fabrics.
It was found that the hight of absorbed water increased with increasing twists, but decreased when excessively twisted. It was explained that water was absorbed mainly through the capillaries formed in the threads and the diameter of the capillary was influenced by the amount of twist. The hydrophobic fibers as polyester do not always show lower values compared with hydrophilic fibers as cotton.抄録全体を表示PDF形式でダウンロード (729K)
