This study was performed to develop face towel fabrics that reflect consumer's tactile preferences. Three different kinds of pile fiber (100% cotton, 50% cotton/50% bamboo, 100% bamboo) of the towel fabrics were selected for the test. The towels were laundered one, five and 10 times repeatedly in a normal washing condition, and fabric softeners were applied to the towels that were laundered 10 times. The flexibility and absorbency (absorption rate and water absorptivity) were evaluated by laundering times of the face towels. Male and female university students evaluated their subjective sensations of the face towels. The flexibility of towel fabrics showed no significant difference according to type of pile fiber or laundering time. The absorbency of the towels was significantly different according to the type of pile fiber and laundering time. The absorption rate was higher in 100% bamboo fiber, and water absorptivity was higher for cotton fibers. There were no significant differences in subjective sensation according to the type of pile fiber of towels before laundering. As the frequency of laundering increased, the tactile preference for the towel slightly decreased. The 100% bamboo towel was rated the most comfortable among the three kinds of towels. The tactile preference for the towels was influenced by smoothness, fabric softness, and softener treatment, in that order.

타월은 소비자가 구매할 때 촉감을 중요시하므로 염색 후 가공 시 유연제를 사용한다. 그러나 반복 세탁 후에는 유연가공제의 탈착으로 초기의 유연성을 잃게 되고, 유연성 유지를 위해 후 가공시 유연제를 다량 사용할 경우 타월의 흡수성을 감소시키게 된다. 유연제는 이온성 별로 다양한 종류가 시판되고 있으나, 수중에서 음으로 하전된 면섬유와 이온결합이 가능한 양이온성 유연제가 가장 많이 사용되고 있다. 양이온성 유연제는 4급 암모늄 화합물로 항균효과도 부수적으로 타월에 부여한다. 본 연구에서는 반응성기를 도입한 양이온성 유연제를 합성하여 시판 유연제와 사용량에 따른 유연효과, 내세탁성을 비교하였으며, 또한 염색 후 유연가공한 타월의 색상변화도 조사하였다. 합성한 양이온성 유연제는 친수성의 특성도 유지하면서, 5회 세척 후에도 개선된 유연효과를 나타내었다.

의류, 타월, 와이퍼 등 대부분의 섬유제품은 수분을 흡수하는 능력이 요구되는데, 여기에서 흡수란 고체 표면에 부착되어 있던 비교적 점성이 낮은 액상 물질, 즉 물 및 용제류 등이 섬유 집합체의 표면에 젖으면서 모세관현상에 의해 표면으로부터 내부로 이동한 다음 방출되지 않고 그 상태를 유지하는 현상을 말한다. 이러한 섬유집합체의 흡수 특성을 정확히 규정하기 위해서는 실제와 같은 상황에서 정확하게 흡수 속도와 흡수량을 측정할 수 있는 방법이 요구되는데 기존의 실험 방법들은 미흡한 점이 다소 있었다. (중략)

Recently towel cloth has a good prospect as sports wear and out fashion wear. So we will discuss correlational effects between towel cloth quality and it's physical properties. In order to investigate the effect of pile length on the stiffness and absorption of the towel cloth, some experiments have been carried out, and then analyzed by the correlation coefficient.

응답변위법에서 이용되는 동지반강성계수의 적절한 평가법에 대한 제안을 하였다. 현재까지의 지진피해조사 및 장기간의 지진관측사례는 지반이 공진할 때의 변형모드가 지중구조물의 피해에 가장 직접적으로 관련이 있는 것으로 알려져 있다. 따라서, 지중구조물의 축방향의 지반의 변형모드와 그 타월 진동수를 특정하여 동지반강성계수를 평가했다. 동지반강성계수는 지반의 공진상태를 상정하고 있기 때문에 결과로써 지진파의 축방행 파장의 영향을 받지 않고, 관상구주물의 반경과 표층두께의 비, 표층두께에 대한 구조물의 매설위치, 표층지반과 기반의 임피단스비 라고 하는 3개의 무차원 변수에 의해 표현된다.

This study examined 12 types of towels with differing fabric material, function, quality, printing, pile length, twist, etc. from a towel company which manufactures and distributes products domestically. After 3 months of use by consumers, a consumer satisfaction survey was administered and results analyzed. Four types of towels were assigned to each group and the towels were used every day for 3 months. Participant feelings after using the towel for the first time and after using it for three months were investigated. The questionnaire consisted of 26 questions on a 5-point Licket-type scale. The first 13 questions measured perceptions of absorption, touch, fine fiber loss, contamination, deformation, drying speed, and design. Other questions compared differences between the two towel types in terms of their material, function, quality, printing, pile length, and degree of twisting. Results showed that, with regards to weight, consumers preferred towels between 130~150g and a thickness of around 1.7~1.8mm. The bamboo towel was considered superior to the cotton towel in terms of sense of touch and did not happen linter after washing. The antibacterial towel was considered better than the cotton towel in terms of absorption but in terms of contamination, participants felt the antibacterial towel became dirty more easily than the cotton towel. We thought that it might be influence of the color of towel. Low-quality towels became stiffer and misshapen more easily than higher-quality towels. But the study showed that the consumers did not perceive significant differences in the towels' quality. Printed towels became thinner and their color changed more with washing. The consumers preferred the design of jacquard towels to printed towels. Towels with short piles was happened more linter than the towel with long pile after washing. Non-twisted towel were better than the highly-twisted towel in terms of sense of touch and absorption but the non-twisted towel happened more linter after washing and became dirty more easily.

The purpose of this study was to evaluate the relationship between the tactile sensation and mechanical properties of towel. Six kinds of towels with different surface structure and fiber composition were used for this study. To evaluate the tactility of towel, 36 adjectives were collected and then 11 adjectives were selected. The subjective evaluation was examined by one to one comparative method and by blind test for estimating the only the sense of touch of the towels. Kawabata's Evaluation system for fabrics was used to measure the mechanical properties which are tensile, bending, shear, compression, surface, weight, and thickness of six towels. The results are as follows; First, surface structure of the towels had an effect on estimation the sense of touch. Pile surface was evaluated thicker, compacter, more cushiony, and more elastic. Waffle surface was evaluated knottier and rougher, and microfiber suede surface was evaluated softer and denser. Second, the highest value of the mechanical properties measured were G, 2HG, B, and SMD of 100% cotton 100% pile, WC, T, and W of elban loop pile, WT, 2HB, and LC of 100% cotton cut pile, RT and MIU of microfiber suede, and RC of microfiber waffle. Third, the 11 adjectives were correlated with more than one mechanical property. 'Knotty' and 'rough' were correlated with MMD and SMD, 'soft' were correlated with B, 2HB, MMD, and SMD. 'Thick', 'heavy', 'compact', and 'elastic' were correlated with WC, T, and W, 'cushiony' was correlated with WC. 'Stiff' was correlated with B and 2HB, 'dry out' was correlated with RT, WC, MIU, and T. 'Dense' was correlated with RT and SMD.

파일 직물은 높은 기공성과 유체흡수 및 보온성이 뛰어나, 타월, 행주와 같은 청소직물 뿐 아니라 침장 및 의류용 소재에도 널리 사용되고 있다. 최근 경편분야에서 극세사를 이용한 제품이 다양한 용도로 적극 활용되고 있으며 환편 제품으로 가볍고 터치감이 특징인 Polar Fleece가 저렴한 가격으로 소비자들의 관심이 증대되고 있다. 이러한 소비시장을 고려해 볼 때 이 두 가지가 함께 공존하는 제품 개발이 절실하지만, 극세사 제품은 트리코트 경편제품이고 Polar Fleece로 활용하는 제품은 환편에서 후가공 기술을 응용한 제품으로 생산기계와 가공공정이 다르며, EF Velboa와 Polar Fleece 2종류 원단의 본딩으로만 가능하기 때문에 환경적으로도 유해하다. 이에 본 연구에서는 덕산엔터프라이즈(주)에서 경편조직과 원사의 특성을 고려하여 본딩 공정없이 표면 은 EF-Velboa, 이면은 Polar Fleece와 같은 부드럽고 고급스러운 외관을 동시에 발현하는 3D 입체구조를 가진 원단을 개발하였다. 또한 개발된 원단의 다양한 용도전개를 위해 염색프로그램, 균염성, 견뢰도 테스트를 진행하였으며 향후 제품군으로의 활용 가능성 여부를 검토하였다.

이 논문은 우리나라 주식시장에서도 외국의 주식시장에서처럼 1월효과(January effect)가 존재하는지의 여부를 검증하였다. 분산분석(分散分析), 공분산(共分散) 분석(分析), Tukey의 HSD(Honestly Significant Difference)검증의 결과, 우리나라의 주식시장에서는 1월, 2월, 3월, 4월 등에서 타월에 비해 통계적으로 유의한 높은 수익률을 실현하였음을 확인하였다. 미국의 주식시장에서처럼 월별효과가 1월에만 국한하여 발생하는 것이 아니라 연초의 여러 달에 걸쳐서 지속적으로 일어난다는 사실은 특기할 만하다. 또한 이러한 월별효과는 소규모의 고위험 주식에만 국한되어 일어난다는 미국의 주식시장과는 달리, 우리나라의 경우에는 규모(規模)와 위험(危險)에는 큰 영향을 받지 않았으며, 산업별 분류와도 별 관련이 없었다. 과거의 주가과민반응(株價過敏反應)을 정정하는 시기도 미국에서는 1월에 국한되었으나, 우리나라의 경우 앞에서 언급된 바와 같이 연초의 여러 개월에 걸쳐서 지속적으로 일어나고 있음을 발견하였다. 이러한 본 연구의 결과는 투자자의 투자전략수립에 유용한 정보를 제공해 줄 수 있을 것이나, 여러 가지 한계로 말미암아 우리나라의 주식시장이 약형(弱型)의 정보(情報) 효율성을 가지지 못한다고 단언할 수는 없을 것같다.

The objective of this study is to develop eco-friendly, functional towel material utilizing cotton-Modal-chitosan blended(C-M-CH) yarn and natural dyeing with mugwort colorants. Dyeing properties of towels with mugwort colorants were studied by investigating the effect of dyeing conditions including concentration of mugwort colorants, dyeing temperature, and dyeing time, and the effects of mordants on dye uptakes were investigated. The C-M-CH towel showed better dye uptake than 100% cotton towel with mugwort colorants. The shade of towels got darker and red-yellowish tint increased by mordanting. Comparing with 100% cotton towel, the colorfastness of dyed C-M-CH towel was satisfactory showing above 3 grade which is the lowest grade to washing fastness. The antibacterial activity against Staphylococcus aureus and deodorization performance of towels were excellent and improved by dyeing with mugwort colorants. From the results obtained, it is concluded that the cotton-Modal-chitosan blended towel dyed with mugwort colorants can be used practically for an eco-friendly and multi-functional towel materials with excellent absorbance and drying properties.
