The physical properties and biodegradability of cellulose fabrics, such as cotton and rayon, are expected to vary with textile care. In this study cotton and rayon fabrics were washed repeatedly with detergents, bleaches, or softeners. The changes of physical properties were investigated by measuring retention of breaking strength, shrinkage, handle, and the fiber surface was observed by SEM. The biodegradability of fabrics was also estimated by soil burial test. The results were as follows. Cotton fabrics laundered repeatedly by detergents and bleaches lost virtually no strength. The breaking strength of the rayon fabrics decreased by about 17%∼25% after repeated launderings. Shrinkage in weft direction was much larger than that in warp direction. Bending rigidities of both fabrics decreased remarkably within 10 wash cycles. Shear rigidity in cotton fabrics increased continuously with repeated washing cycles, however, that in rayon fabrics did not show any change as washing went on. Friction coefficient increased in both fabrics after 10 wash cycles, and this is thought to be attributed to the wrinkle, interlocking of hairs, surface damage resulted from repeated washings. In cotton fabrics made of staple yarns, short hairs on the yarn surface entangled together with repeated launderings. This resulted in the continuous increase in % shrinkage, shear rigidity, friction coefficient. Rayon fabrics made of filament yarns, however, did not show this phenomenon. Softener treated fabrics showed the lowest values in bending rigidity, shear rigidity and friction coefficient because the cationic surfactants adsorbed on the fiber surface behaved like lubricants. The biodegradability of fabrics was noticeably affected by the composition of washing solutions. The fabrics washed with detergents and bleaches were decomposed faster than those washed with the others were and the cotton fabrics washed with detergents and softeners hardly degraded. The fabrics soiled with milk were decomposed almost completely and those soiled with Palmitic acid did not degrade greatly.

The global laundry detergents market in 2021 was valued at nearly $121 billion, with consumers being reported as heightening their search for hygienic products capable of fighting viruses. Therefore, the researchers undertook a study to determine how product innovation (PI), product quality (PQ), and product attitude (PA) effects Thai consumers' satisfaction (CS) with their purchase of laundry detergent and fabric softener. After the questionnaire's validity and reliability confirmation, the authors used multi-stage random sampling by region and province in January and February 2022 to collect 520 questionnaires. LISREL 9.10 was used in the CFA and SEM analysis of the six hypotheses, which were determined to be supported. The results showed that all three causal variables positively influenced CS, with a total effect (TE) R² value = 87%. Also, latent variable total effect (TE) values showed that PI was strongest (0.93), then PQ (0.56), and finally, PA (0.54). Therefore, consumer satisfaction is essential in a firm's ongoing development and sustainability in a highly competitive, globalized world. Organizations must develop competitive strategies that adjust to consumer needs. Management must monitor online and social media sources where product reviews are given and adjust their strategies accordingly.

본 연구는 소비자의 선호 촉감을 고려한 세면용 타월 개발에 도움을 주고자 수행되었다. 타월의 바탕조직은 동일하지만(면섬유), 파일을 구성하는 섬유의 종류가 서로 다른 3종(면 100%, 면 50% / 대나무 50%, 대나무 100%)을 시료로 선정하였다. 타월을 표준 세탁조건으로 반복세탁을 실시하였으며, 10회 세탁한 타월에 대하여 섬유유연제를 처리하여, 세탁에 따른 유연성과 흡수성(흡수속도와 흡수율) 등의 성능 변화를 고찰하고 대학생 남녀 소비자를 대상으로 주관적 감각과 촉감 선호도를 평가시켰다. 세탁횟수와 파일섬유의 종류에 따라 타월의 유연성은 유의한 차이를 보이지 않았다. 타월의 흡수성은 세탁에 따른 파일섬유의 종류에 따라 유의한 차이를 보여, 흡수속도는 대나무섬유 100%로 된 타월에서 높았으나, 흡수율은 면섬유로 된 타월이 높았다. 세탁 전 타월의 파일섬유 종류에 따른 주관적 감각 평가는 유의한 차이가 없었다. 세탁이 반복될수록 파일섬유의 종류에 따른 주관적 감각은 유의한 차이를 보였으며, 섬유유연제 처리시 더 부드럽고 매끄러우며 촉촉해진다고 평가하였다. 세탁 전 타월에 대한 촉감 선호도는 선호하는 편이었으나, 파일섬유종류에 따른 유의한 차이는 없었다. 세탁횟수가 증가함에 따라 타월에 대한 촉감 선호도는 다소 저하되었으며, 대나무섬유로 된 타월의 촉감을 가장 선호하였다. 타월의 촉감 선호도에는 평활감, 유연감 등의 주관적 감각과 섬유유연제 처리가 영향을 주었다.
