드레스셔츠 소재의 반복세탁과 다림질에 의한 물성변화에 관한 연구 = (A) study on the changes in properties of dress shirts by repeated washing, drying and ironing

다국어 초록 (Multilingual Abstract)

Men?s clothes seldom have periodic changes based on tailored suit and the patterns are not various. Recently, men?s interest in clothing is getting higher and the trend of expressing their individualities is becoming dominant. Especially, as one of the factors in fashion that express their own individualities, dress shirts are doing the important role in social life as well sanitary role that absorb the eliminating secretion from the bodies as a clothes that touch the skin.

When the importance of keeping is growing along with the interest in clothing, while managing the clothes in daily life, the textiles might be damaged by laundry, drying and ironing. While washing, processed material and thickener fall off and the textiles inflates or shrinks, and it damages the textiles bringing such as structure transformation of the cloth by the temperature of water, the concentration of detergent, the duration of washing and the pressure.

It is informed that the considerable part of the complaint about textile goods received in consumer agency by consumers? lack of knowledge and careless about proper handling of each product is related to laundry. For efficient and organized management of clothing, the formation of clothing and the properties of textiles must be understood clearly and clothing must be managed with proper handing. Also, the guidelines of handing clothing, such as symbol of quality or handle with care, need to be improved to be utilized easily and simply in real lives.

In this study, rayon 100% which is frequently used as the fabric of dress shirts, polyester 100% and blended fabric which is polyester/cotton 60/40 are chosen, and laundry, drying, ironing are done 0, 10 and 50 times repeatedly. After, the change in properties and surface of the samples are compared and studied.

The following is the result of this study.

First, in the change of weight, all three samples showed the tendency of decrease, and the blended fabric, polyester/cotton 60/40, showed the biggest rate of decrease (3.8 %).

Second, in the change of thickness, all three samples showed the tendency of increase.

Third, in the change of density, all three samples showed the tendency of increase.

Fourth, in the change of abrasion strength, each sample showed a different result. The abrasion of rayon and polyester increased and that of the blended fabric, polyester/cotton 60/40, decreased.

Fifth, the tensile strength of all three samples decreased. The strength of weft and warp in rayon and polyester decreased. The strength of warp in blended fabric, polyester/cotton 60/40, decrease after the 10-time-laudry and increased again after the 50-time-laundry becoming the same strength as before the experiment. The tensile strength of weft decreased according to the number of times of laundry.

Sixth, in the change of drape, rayon showed decrease after the 10-time-experiment and increase of a narrow range after the 50-time-experiment. Polyester didn?t show any difference until the 10 times but showed decrease after the 50-time-experiment. The drape of blended fabric, polyester/cotton 60/40, became better as the number of times increases and it became better about 70 % compared to the one before the experiment.

Seventh, as a result of investigating the surface with SEM, fuzz was generated a lot due to the laundry in rayon and strips of strands were cut due to friction. In polyester, hardening of strands was occurred. On the surface of the blended fabric, polyester/cotton 60/40, fuzz was generated and the structure of fabric was transformed due to the repetitive experiment.

According to the result of the study, due to the repetitive laundry, drying and ironing, since textiles were damaged, the decrease of strength and the change in surface were shown and the extent of damage was acquired.

For further study, the cause of the phenomenon that the degree of abrasion increases in rayon and polyester as the number of the experiment grows needs to be found.
