Cotton fabrics were immersed in aqueous solution of N-methylmorpholine N-oxide(NMMO) with various concentrations, padded by 300% of pick-up, concentrated at $90^\circ{C}$ for 30min under constant-length condition, washed, and dried, to examine a possibility of linen-like finishing by the solvent bonding between fibers. With increasing the concentration of NMMO, cross-sections of fibers changed to oval or polygonal shapes and not only the fibers but also the warp and weft were bonded each other, which produced linen-like effect on the fabrics in the aspects of appearance and mechanical properties such as the Increase of stiffness and shear properties. The thickness, moisture regain and dyeability were increased with the concentration of NMMO.

The purpose of this research was to investigate the property of sensibility of silk fabrics by the linen-like finishing-used polyurethane resin. Subjective evaluations of preference and related sensory descriptors were estimated. Also, related physical and psychological variables were measured. And their correlations were investigated. The value of EM, WT, WC, MIU, and qmax of silk fabrics treated with polyurethane resin decreased and LT, B, 2HB, G, 2HG, 2HG5, and SMD increased. Physical variables which affected on the preference of summer fabrics are B, 2HB, G, 2HG5, qmax, MIU and LT. It was confirmed that silk fabrics treated with polyurethane resin were preferred as a summer fabric. Individual sensibilities that had effects on the preference of summer fabrics were softness including rough and cold. The intensities of weight value on sensory descriptors, which were related with the preference in summer environments, were in following orders: cold, rough, slippery, flexible, stiff and damp. There was no relationship between the subjective evaluation of preference and related sensory descriptors on the fabric and comfort sensation of fabric was derived from psychological variables

The polyester fabrics were treated with the chitosan with various solubility in optimized treatment condition. The treatment method was discussed to be a high functional finishing for the polyester fabric to obtain the high moisture absorption and anti-microorganism property by evaluating the effect of the chitosan purification method on the yield and anti-microorganism property of the chitosan. On the other hand, soluble polyurethane was added to the chitosan treatment solution and/or plasma pretreatment was done. The addition of soluble polyurethane give a high add-on ratio as well as a linen like effect of treated polyester fabric. The results were as follows: 1. In the treatment of polyester fabric by the chitosan solution, a soluble PU resin and low temperature plasma treatment were done to obtain high binding force between the fabrics and the chitosan. The add-on rate and the moisture absorption ratio of the fabrics treated with the chitosan-PU after treated with the plasma slightly increased more than those of the fabrics treated with the chitosan only. 2. Anti-static property of the fabrics treated with the chitosan decreased rapidly with increasing of the chitosan concentration. The washing fastness of the fabrics treated with the chitosan-PU after treated with the plasma was better than those of the fabrics treated with chitosan only. The wrinkle resistance of the treated fabrics decreased constantly with the concentration of the chitosan. The bending rigidity of the treated fabrics increased greatly. On the treatment of polyester fabric under optimum condition, the microorganism reduction rate kept above 90％ after 10times launderings. 3. As the polyester fabrics which has flat yam was used as a weft yams were treated with the chitosan-PU as give a functional finishing effects such as durability, moisture absorption, anti-static and anti- microorganism property. Treated polyester fabric showed a good functional finishing effect and a linen like property.

마 섬유는 흡습성이 좋고 건조가 빠르고, 습윤 시 강도가 증가되며 열전도율이 크고 통기성이 크며, 강도와 내열성이 천연 섬유 중 가장 우수하며 매끄러운 표면을 가지고있어서 광택과 방오성이 좋다. 그러나 세사방적이 어렵고 강연도가 지나치게 커서 의복소재로서 극히 제한적으로 사용되어왔으나, 최근에는 큰 강연도를 장점으로 활용하여 여름용 의복소재로 다시 각광받고 있다. 따라서 면, 레이온, 셀룰로오스계 섬유제품들에 대하여 마 제품과 유사한 효과를 낼 수 있는 다양한 의마가공법이 개발되어왔다[1,2]. (중략)

First of all, the properties imparted to PET fabrics are resistance to and recovery from creasing or wrinkling when wet or dry; high resistance to stretch in the filament yarns but not in the staple; high abrasion resistance; good texture and appearance; resistance to heat ageing; good chemical resistance and good resistance, behind glass, to sunlight. But, the low moisture regain of PET fabric conduces to static troubles in textile processing. Furthermore, garments made from PET may, during wear, develop electric charges which attract to the fabric particles of soil(dirt, swarf, dust) flying in the air, so that the cuffs of shirts, for example, become soiled quickly and are not easily laundered clean. The sericin constitutes 25$\sim$30％ of silk protein and surrounds the fibroin fiber with sticky layer that supports the formation of a cocoon. The useful biochemical properties of sericin protein are oxidation resistant, antibacterial, UV resistant, hydrophilic property, and good affinity with hydrophobic material. These properties can be used as an improving reagent or a coating agent for natural and synthetic fibers, fabrics, and other intermediate products. The sericin is also applied to cross-link, and can be blended with other materials. In this study, we modified the surface of PET fabric by mixture of sericin finishing agent; sericin, polyuretane binder and 1,2,3,4-butanetetracarboxylic acid (BTCA) cross-link agent. Also, we investigated the finshing effect; moisture regain, stiffness, handle, drape and electrostatic. The moisture regain of PET fabric treated with sericin finishing agent was higher than that of untreated PET fabric. As a result of evaluating influence about handle of PET fabrics treated with sericin finishing agent, it was confirmed that the sericin finishing agent could be use as a linen like finishing agent.

본 연구는 고부가가치의 섬유를 개발하기 위해서 얻어진 다양한 태 특성을 가진 직물의 적절한 용도를 감각적 감성평가를 통해 밝히려는 목적을 가지고, 첫번째 단계로 의마가공용 폴리우레탄 수지로 가공처리한 견직물의 선호감성에 영향을 미치는 직물의 개별감각특성을 알아보고자 하였다. 의마가공용 폴리우레탄 수지를 이용하여 다양한 강경성이 부여된 견직물에 대한 인간의 주관적인 감각을 평가하고 객관적인 특성과 연관지어 보았다. 강경성이 다르게 제작된 견직물과 시판모시로 구성된 9종류의 직물의 까실까실하다, 매끄럽다, 습하게 느껴진다, 뻣뻣하다, 차다, 하늘하늘하다의 6개의 개별감각과 촉감이 좋다와 여름철소재로 선호한다의 종합적 평가를 행하여 9종류의 직물의 위치도를 작성하여 여름철소재의 선호감성과 촉감, 직물개별감각과의 관계를 분석하였다. 분석결과 여름철소재의 선호감성에 영향을 주는 직물의 개별감각은 부드러워서 촉감은 좋지만 까실까실한 감각이 있어 다소 차게 느껴지는 감각임을 알 수 있었으며 의마가공된 견직물이 여름철 소재로 선호됨을 확인 할 수 있었다.
