“…The visual observation of the detergent solutions after washing confirmed the detergency evaluation from the surface reflectance of the soiled fabric. Moreover, the color difference between the unwashed and washed soiled fabrics, which was determined from the complete visible spectrum, 25 had an almost linear relation with the detergency calculated from the K/S values using Equation (1). The washing tests were repeated four to six times for the same experimental condition and experimental errors of D were within AE10%.…”

“…As media for cleaning delicate garments, dry-cleaning solvents such as tetrachloroethylene and hydrocarbon have been commonly used. These solvents have human health effects, environmental impacts and present a fire hazard, 1,2 and therefore will be regulated in the future. Water, which presents ultimate safety to the environment and human body, is an excellent solvent for many compounds.…”

Ultrasonic cleaning in aqueous solutions was performed using various plain-woven fabrics soiled with oleic acid and/or carbon black as model oily and particulate contaminants. Detergency, which was evaluated from the change in the surface reflectance of the soiled fabrics due to cleaning, was promoted by applying ultrasound as the mechanical action for soil removal in the absence and the presence of anionic surfactant. Both soils were removed easily from the filament fabrics compared with the spun fabrics. Ultrasound, as mechanical action, was favorable for removing carbon black even in the absence of surfactant, whereas the addition of surfactant was effective for removing oleic acid without and with ultrasound. In most cases of soiled fabrics, the detergency obtained with ultrasonic washing for 1 min was comparable to that obtained with a drum-type washer, the Wascator (normal and gentle procedures). Heavy fabric damage was observed after washing with the Wascator, especially for the wool and silk fabrics, whereas there was little damage after ultrasonic washing for all fabrics. Conclusively, ultrasound can be effective in laundering for delicate textiles from the viewpoints of the processing time as well as detergency performance.

Performance of tapping washing in comparison with hand washing and front-loading machine washing for knitted wool sweaters

Wool fiber is widely used for clothing in our daily life due to its excellent physical and mechanical properties. However, in the daily laundry process, wool products can shrink severely by strong mechanical action in a warm and moist environment due to the fiber surface scales. Aiming to overcome the difficulty of washing delicate clothes such as wool and silk, Panasonic Intellectual Property Management Co. Ltd. invented a new washing machine for delicate clothes, based on tapping actions. The washing performance of wool sweaters in tapping washing is compared with that of hand washing and gentle and normal machine washing. The results show that tapping washing always gives wool sweaters the best appearance, dimensional stability and mechanical property up to 10 washing cycles. The changes in appearance and mechanical properties of wool sweaters are mainly due to the rate of felting shrinkage. By comparing the magnitude, duration, number of mechanical actions and direction of the forces acting on the fabric in tapping washing, hand washing and gentle machine washing, it can be concluded that the direction of forces acting on the fabric has a significant effect on wool fabric felting shrinkage, and unidirectional force has less effect on felting shrinkage than multidirectional forces. Tapping washing can give the lowest felting rate to wool samples because the forces in tapping washing on all parts of the fabric have a similar direction.
