  • In this study, the effect of innovativeness of external networks on the corporate innovativeness and innovation performance were explored based on web survey data collected from 230 manufacturing companies. Specifically, according to the manufacturers' business categories divided by the technology level, three groups such as advance technology (electronic/IT), mid- to high technology (automobile/machine), and low technology (textile/clothing) companies were investigated to find out which external network influences corporate innovativeness and innovation performance. In the result, textile/clothing companies were not different in company size, history, and innovation effort from advanced technology and mid- to high technology companies. Collectively, the innovativeness of external networks affected corporate innovativeness and innovation performance. In the result by a business category, innovativeness and innovation performance of textile/clothing companies were affected by the innovativeness of competitors, whereas automobile/machine companies in the mid- to high technology group were affected by suppliers. In addition, advanced technology (electronics/IT) were affected by buyers and competitors. These differences suggest that the way to use vertical networks toward upstream (e.g., suppliers) and downstream (e. g., buyers) as well as horizontal networks toward competitors can be different by the business category of manufacturers. The result would provide implications for the academia and the industry.

  • The sheet molding compound composite has been applied divers section. This paper reports processing of carbon fiber reinforced thermosetting composite with diverse resins and which was composed of chopped carbon fiber (30 ~ 60 wt%). Normally the paste that the viscosity is over 15,000 cps has been used in traditional Sheet molding compound (SMC) machine. In this research, SMC machine was designed to make Carbon-sheet molding compound (C-SMC) prepreg which was composed with low viscosity resin (1,800 ~ 2,500 cps increase up to 10,000 cps after aging). In order to confirm the optimal processing condition. Mechanical strength tests including tensile test, shear test, impact test, flexural strength test were conducted on C-SMC composites. Plus we identified the correlation between the mechanical properties and prepreg processing condition (carbon ratio and applied resin).

  • 현재 텍스타일 분야는 활용 범위가 확장됨에 따라 감성과 같은 비물질적인 가치에 관해 관심을 두는 연구들이 증가하는 추세를 보인다. 본 연구의 궁극적인 목적은 디지털 크래프트를 적용한 텍스타일 디자인의 감성적 의의에 초점을 맞추어 실증 연구를 통해 디지털 크래프트를 적용한 감성적 텍스타일 디자인의 생성 가능성 및 활용방안을 제안하는 것이다. 본 연구에서 개발한 주관적 평가 스케일을 통해 측정한 평가결과를 바탕으로 디지털 기술을 적용한 텍스타일 디자인과 디지털 크래프트를 적용한 텍스타일 디자인의 차이를 비교하여 통계적으로 의미가 있는지를 검증하기 위한 실증 연구를 진행하였다. 실험 결과, 디지털 크래프트를 적용한 텍스타일 디자인 작품에 대한 감성 생성 가능성과 활용방안에 대한 몇 가지 의미 있는 시사점을 도출할 수 있었다. 첫째, 에스닉한 감성은 유의한 수준은 아니지만 3번의 비교 분석에서 모두 증가하였다. 둘째, 모던과 클래식한 감성은 모두 감소하였다. 셋째, 디지털 텍스타일 머신과 디지털 텍스타일 머신과 크래프트의 비교 분석에서 펀한 감성이 유의한 차이로 증가함을 보였다. 넷째, 3D 프린팅과 3D 프린팅과 크래프트의 비교분석에서 엘레강스가 유의미하게 증가하였다. 따라서 디지털 크래프트를 적용한 텍스타일 디자인은 사용한 디지털 기술 방식에 따라 에스닉, 펀, 엘레강스한 감성의 전달이 가능할 것으로 예측된다. 본 연구를 통해 도출한 결과를 텍스타일 디자인 개발과 생산 단계에서 적절하게 사용한다면 감성적 텍스타일 디자인의 개발을 위해 효과적으로 작용할 수 있을 것이다. 또한, 본 연구의 결과는 디지털 크래프트를 통한 감성적 텍스타일 디자인에 대해 객관적인 자료를 제공함으로써 향후 학계뿐만 아니라 실무에도 중요한 시사점을 제공해 줄 수 있을 것이라 기대한다.

  • The purpose of this study is to research source of soil which is available for non-detergent course, and to develop optimum non-detergent course of washing machine for water soluble soil. The water soluble soil such as grape juice, soy bean paste and soy sauce were easily removed from the fabric but the oil soluble soils such as sesame oil and steak sauce were insurfficiently removed in washing solution without detergent. In the absence of detergent, amount of residual soils increased linearly with increasing number of soiling and washing. To search optimum conditions of washing for non-detergent course, the effect of temperature, washing time and washing method on detergency of soil in non-detergent washing solution was examined. The optimum washing temperature and washing time for non-detergent course were about $40^{\circ}C$, and 7 minutes, respectively. And in the non-detergent washing solution, midterm drain-resupply of water during washing process was good for removal of water soluble soil.

  • This study was carried out to investigate the effect of washing machine type (drum or pulsator) on the behavior of clothing management and consumer satisfaction. The data were collected via questionnaires from 408 consumers and were analyzed through factor analysis, ANOVA, Cronbach's Alpha, utilizing SPSS 10.0. The results of this study were as follows: 1) 39.2% of consumers used drum washer and the number of users has increased sharply in five years. Drum washer consumers hold larger capacity washer than pulsator washer consumers. 2) Young people(under 40) showed statistically significant differences in terms of washing concern and the kinds of detergents, while old people(40 and above) showed statistically significant differences in terms of checking the label, preparing the laundry, and hand-washing. Married women showed statistically significant differences in checking the label, preparing the laundry, and hand-washing. 3) In terms of clothing management behavior with the type of washing machine, drum washer consumers showed statistically significant the amount of detergents, while pulsator washer consumers showed statistically significant handwashing and kinds of detergents. 4) In terms of customer satisfaction with the type of washing machine, drum washer consumers showed statistically significant brand satisfaction.

  • This paper proposes a robust tension control algorithm for the let-off and take-up system driven by servo motor which is robust to disturbance and tension variation by using SVR(Support Vector Regression). Quality of textile goods in fiber manufacturing process highly depends on control of let-off, take-up and tension which are essential for constant tension control of yarn and textile fabrics and correct length of them. The physical properties of textile fabrics are very sensitive to several factors(temperature, humidity, radius change of warp beam etc.) which result in tension change. Rapid development of fiber manufacture machine for higher productivity requires control system for let-off, take-up and tension for robustness to sharp tension-variation and quick response. The validity and the usefulness of the proposed algorithm are thoroughly verified through numerical simulation.

  • 현재까지 다양한 연속적인 공정시스템은 섬유, 제지 및 인쇄 등 많은 산업응용 분야에서 사용되고 있다. 이러한 응용분야에서 공정처리를 받고 있는 제품에 가해지는 장력은 원료의 공급속도와 생산되는 제품의 방출 속도간의 속도차에 의해 변화될 수 있다 특히, 섬유공정에서 공급속도와 방출 속도간의 속도차나 관성효과에 의해 발생되는 장력변동은 제품의 품질을 저하시킬 수 있다. 따라서 섬유공정에서 이러한 요인들에 의해 발생되는 장력 변동을 적절한 방법에 의해 보상하는 것은 매우 중요한 문제이다. 본 논문에서는 이러한 문제를 해결하기 위하여 섬유공정에서 많이 사용되고 있는 환편기 시스템에서의 장력제어 문제를 다루고자 한다. 먼저 일반적인 연속공정의 권취 메커니즘에 대한 장력 관계식을 모델링한다. 다음은 환편기 시스템에서 풀림롤과 감김롤을 효율적으로 구동하기 위하여 풀림롤과 감김롤간의 속도차와 관성특성을 고려한 새로운 장력제어 방법을 제시한다. 다양한 실험을 통하여 제안된 장력제어 방법이 주어진 환편기 시스템의 공정구간에서의 장력제어 성능을 향상시킬 수 있음을 보인다.

  • Formulations of compact and supercompact heavy-duty detergents, which are being used widely around the world, differ from those of conventional heavy-duty detergents. Significant differences in composition exist between the compact detergents and the conventional detergents. The compact detergents have a higher content of surfactants, oxygen bleach and enzymes than the conventional detergents. We have studied to find the most effective washing conditions of artificially soiled cloths with a commercial, supercompact, heavy-duty detergent and a drum type washing machine which is becoming the preferred type in Korea. Moreover, we have studied the washing performance with an impeller type washing machine, which has heretofore been the most popular type in East Asia. With the drum-type washing machine, washing performances improved as the washing temperatures went up and the washing times were lengthened. Though the rate of soil removal with a double recommended dosage was higher than with the recommended amount at $20^{\circ}C$, the effects of the higher dosage decreased as the washing temperatures increased. Finally, the washing performances with the two different dosages were the same at $60^{\circ}C$. The washing performances at $40^{\circ}C$ with the recommended dosage for 90 minutes were the same as with the double recommended dosage for 45 minutes. The soil removal efficiencies with the impeller-type washing machine were much lower than those of the drum-type washing machine. The reasons for this were the higher bath ratio that led to the lower concentration of wash liquor, the shorter washing time, and the lower washing temperature.
