푸새처리후의 직물강도의 변화를 알아보기 위하여 가정푸새의 주류인 綿織物, 麻織物, T/C 織物에 糊料의 種類와 濃度, 푸새처리전 직물의 水分率, 푸새처리후 다림질온도에 변화를 주어서 실험하였다. 푸새후 직물의 강도는 현저히 증가하였으며, 처리조건의 변화에 따라서 강도 증가도에 차이가 나타났다. This paper aims to examine the breaking strength of cotton, hemp, and T/C fabrics sized by rice, wheat, potato, corn flour and P.V.A. The effect of experimental variables such as fabrics, sizing agents, the concentration of sizing agents, the moisture regain of unsized fabrics and the ironing temperature showed the following results. 1. The breaking strength of hemp fabrics was highest, T/C fabrics second and cotton fabric was lowest among the sized fabrics. 2. When the fabrics were sized, the breaking strength increased. The breaking strength of sized fabrics increased in order of wheat, potato, rice flour, P.V.A. and corn flour for cotton and hemp fabrics, and P.V.A., rice, potato, wheat and corn flour for T/C fabrics. Corn flour showed the lowest among all the others mentioned above. 3. The breaking strength of the sized fabrics was influenced by tenecity more than density of gray fabrics. 4. To a certain extent, the higher the concentration of sizing agent, the higher the breaking strength. 5. The fabrics with moisture regain of 20% before sizing had the highest breaking strength. 6. The highest breaking strength was obtained at the case of sized fabrics at the temperature of 180℃ for cotton, 230℃ for hemp, and 160℃ for T/C fabrics.

The purpose of this study is to investigate the results of dyeing on silk fabrics treated with wheat flour juice to get better handicraft dyeing with sharp lines and exact shades on the dyeing portion. The followings are the results of this study. 1.The initial modulus of fabrics was increased by wheat flour juice. 2.The absorbing rate of dyed fabrics treated with wheat flour juice was decreased when the concentration of wheat flour juice was increased. 3.The K/S value and color difference of fabrics treated with wheat flour juice were increased when the concentration of wheat flour juice was increased. 4.The value and chroma of color of dyed fabrics treated with wheat flour juice were decreased a little.But the yellowish tone appeared when dyed fabrics were treated with soybean juice was not seen when dyed fabrics were treated with wheat flour juice. 5.The color fastnesses to washing, perspiration, and rubbing were good or excellent, but color fastness to light was poor.The color fastness to washing, perspiration, and light improved a little (except for color fastness to wet rubbing) after being treated with wheat flour juice. 6.The sharpness of the dyed portion was increased with an increase in the concentration of wheat flour juice because the wheat flour juice (thickening agent) prevented penetration. In other words, dyed fabrics treated with wheat flour juice used as thickening agent can be expected to have many benefits ; good dyeability, economical costs, easy purchasing and handling, and high yield of color.

被服着用시 여러가지 요인에 따라 부착되어 衣服의 衛生的 美的, 耐久的인 기능을 저하 시키는 汚染을 제거하여서 被服地가 생산될때 가졌던 本來의 機能을 회복시키는 것이 洗濯의 目的이다. 그러나 洗濯이 되풀이되면서 纖維가 가졌던 柔軟成分이 消失되어서 그 촉감은 거칠어지고 耐汚染性, drape성, 體型保存性 등이 저하되고 電氣的인 층격, 皮膚疾患 등 身體的인 障害, 快適性의 低下 등 여러가지 문제들이 생긴다. 또 脫脂力이 끈 合成洗劑의 利用率이 커지면서 의복류의 촉감은 더 큰 문제가 되고 있다. 그리하여 최근에는 家庭洗濯時에 柔軟劑를 처리하여 柔軟效果를 얻고 있다. 그러나 柔軟劑는 그 化學的인 조성에 따른 柔軟度의 差異, 처리된 洗濯物의 構成纖維 및 纖維構造物의 形態, 種類에 따라서 그 處理條件이 달라져야 할 것이다. 그리하여 본 연구에서는 柔軟劑 처리시 柔軟性이 가장 크게 향상되는 處理條件 및 方法을 얻기 위하여서 cotton, T/C(45/55), T/C(65/35), polyester직물에 시판 家庭用 柔軟劑 4종류로 처리시의 濃度, 溫度, 時間, 처리전의 脫水率에 변화를 주어서 實驗하여 다음과 같은 결론을 얻었다. 1.cotton 직물은 柔軟劑 處理效果가 크지 않았으나 polyester직물, polyester混紡직물은 그 효과가 컸다. 2.polyester의 混紡率이 클수록 柔軟劑 처리濃度, 처리전의 脫水率은 크게, 處理溫度는 낮게 처리하는 것이 剛軟度를 增大시킨다. 3.cotton 직물은 0.05%의 濃度, 40℃의 處理溫度, 30-50%의 처리전 脫水率로 5분간, T/C(1)직물은 0.1-0.2%의 濃度, 30-40℃의 處理溫度, 50-70%의 처리전 脫水率로 5-10분간, T/C(2)직물은 0-2%의 濃度, 20-30℃의 處理溫度, 50-70%의 처리전 脫水率로 5-10분간, polyester직물은 0.4%의 濃度, 20-30℃의 處理溫度, 70-100%의 처리전 脫氷率로 5-10분간 처리하는것이 剛軟度를 가장 크게 하는 조건이다. 4.原料纖維의 混紡率보다도 織物構成絲의 纖度, 織物의 密度 등 纖維構成狀態에 의해서 柔軟劑 처리효과가 더 영향을 받는다. 5.polyester의 混紡率이 클수록, 織物의 密度가 클수록, 織物構成絲가 가늘수록 柔軟制 처리시 剛軟度는 커진다. In order to treat the soft agent for home use more efficiently on fabrics, this paper aims to examime the flexibility and the feeling of smoothness and softness of cotton, T/C(45/55), T/C(65/35), polyester fabrics treated with four kinds of soft agent for home use on marketing. The experimental variables such as the concentration of soft agents, the treating temperature, the treating time and the dehydrating rate of the untreated fabrics showed the following results. 1.Cotton fabrics showed lower flexibility of the treating effect of the soft agent but polyester and polyester blend fabrics showed higher one. 2.For fabrics with larger portion of polyester fabric, it was more effective to treat with higher concentration, hider dehydrating rate of the untreated fabrics and lower temperature. 3.When each fabric was treated with following conditions, it showed the highest flexibility. Cotton fabric ; concentration ; 0.05%, temperature ; 40℃ dehydrating rate ; 30-50% time ; 5min. T/C(45/55)fabric; concentration ; 0.1-0.2%, temperature ; 30-40℃ dehydrating rate ; 50-70% time ; 5-10min, T/C(65/35)fabric; concentration ; 0.2% temperature ; 20-30℃ dehydrating rate ; 50-70% time ; 5-10min. polyester fabric ; concentration;0.4% temperature ; 20-30℃ dehydrating rate ; 70-100% time; 5-10min, 4.The flexibility and the feeling of smoothness and softness were effected by the characterists of the fabric such as the fineness and the density more than the blending ratio of the fabric. 5.The larger the portion of polyester fibre, the higher the density and the finer the yam of the fabrics, the better the treating effect of the soft agents.

吳和子 慶南大學校 附設 工業技術硏究所 1994 硏究論文集 Vol.12 No.-

최근 合成纖維의 開發發達은 우리의 衣生活을 매우 풍부하게 하고 있으나, 合成纖維의 최대의 문제인 帶電成은 실제 被服生活에 여러 가지 문제를 일으키고 있으며 이에 대한 生産科學적인 면에서의 연구가 활발하게 진행되어지고 있다. 아울러 消費科學적인 면에서도 특히 家庭洗濯후 간단하게 처리할 수 있는 家庭用 帶電防止劑가 최근에는 많이 開發 市販되어 대부분의 家庭에서 이용하고 있다. 그러나 帶電防止劑는 化學的인 組成에 따른 帶電防止性의 정도, 처리될 組織 및 組織構造物의 形態, 種類, 강연성 등의 촉감에 따라서 조정되어 처리되어야 되대의 효과를 얻을 수 있다. 그리하여 T/C(45/55), T/C(65/35), polyester직물을 試料로 하여서 市販中인 家庭用 帶電防止劑 4종류로 帶電防止劑의 濃度 처리溫度, 처리時間, 처리전의 脫水率에 변화를 주어서 실험하여 다음과 같은 결론을 얻었다. 1. polyester의 混紡率이 클수록 帶電壓은 높았고 半減期는 길었으며 또 帶電防止劑의 효과도 컸다. 특히 polyester직물은 半減期의 저하율이 90%정도 이었다. 2. polyester의 混紡率이 클수록 처리濃度, 처리時間, 처리전의 脫水率은 크게, 처리 溫度는 낮게 처리하는 것이 효과적이다. 3. T/C(45/55)직물은 처리濃度 0.05%, 처리溫度 30∼40℃, 처리時間 3∼5분, 脫水率 30∼50%로, T/C(65/35)직물은 처리濃度 0.05∼0.1%, 처리溫度 5분, 脫水率 50∼70%로, polyester직물은 처리濃度 0.4%, 처리溫度 20℃, 처리時間 10분, 脫水率 70∼100%의 조건으로 처리 하였을 때 帶電防止機能이 가장 컸다. 4. 脫水率, 처리時間, 처리濃度, 처리溫度의 순서로 帶電防止 機能에 영향을 준다. . In order to treat the antistatic agents for home use more efficiently on fabrics, this paper aimed to examine the charged voltage and the half-life of T/C(45/55), T/C(65/35) and polyester fabrics treated with four kinds of antistatic agent for home use on marketing. The experimental variables such as the concentration of antistatic agents, the treating temperature, the treating time, and the dehydrating rate of the untreated fabrics showed the following results. 1. The larger the portion of polyester fibre, the higher the charged voltage and the longer the half-life of the fabrics. But the larger the portion of polyester fiber, the better the treating effect of the antistatic agents. Especially the half-life of the polyester fabrics reduced by 90%. 2. For fabrics with larger portion of polyester fibre, it was more effective to treat with higher concentration, longer time, higher dehydrating rate and lower temperature. 3. When each fabric was treated with following conditions, it showed the highest antistic effect. T/C(45/55)fabric concentration: 0.05%, temperature : 30∼40℃ time : 3∼5min. dehydrating rate : 30∼50% T/C(65/35)fabric concentration : 0.05∼0.1%, temperature:20℃ time : 5min. dehydrating rate : 50∼70% polyester fabric concentration : 0.4%, temperature : 20℃ time : 10min. dehydrating rate : 70∼100% 4. The antistatic effect was increased according to the order of dehydrating rate, treating time, concentration of antistatic agents and treating temperature.

오화자 慶南大學校 附設 工業技術硏究所 1998 硏究論文集 Vol.15 No.3

경험적으로 공예염에서 방삼제로 이용되는 콩즙의 방삼효과를 확인하며 동시에 콩즙처리후의 염색성에 관하여서 고찰하기 의하여서 견직물에 콩즙처리하여 실험하였다. 콩즙처리한 견직물은 초기탄성율이 저하되어 drape성이 커졌고 흡수율이 증대되었으며, 같은량의 염료로 보다 농색의 염색을 할 수 있었다. 그리고 염색한 무늬의 가장자리가 보다 선명하고 예리하게 염색되었다. 고로 실제 염색에서 위생적인 성능과 심미성과 경제성이 크게 향상될 것으로 기대된다. This study was carried out to investigate ht change of physical properties and dyeability of silk fabrics treated with soybean juice for improvement if elegant clothing appearance and economical dyeing. The results were as follows. 1. The initial modulus decreased with increasing concentration of soybean juice. 2. The absorbing rate increased with increasing concentration of soybean juice. 3. The color yield increased with increasing concentration of soybean juice. 4. A little improvement of colourfastness to washing was made but negligible changes of colourfastness to abrasion, perspiration and light were made for dyed silk fabrics treated with soybean juice. 5. The sharpness of dyed portions increased with concentration of soybean juice. In other words, dyed fabrics treated with soybean juice were expected to have improvements of elegant and sanitary performances by lower initial modulus, better guality of dyeing and higher absorbing rate and to have economical profits by higher yield of colors.
