Electrostatic flocking processing is used for many products for the purpose of decoration and function impartation. However, the official method for evaluating flocking strength of electrostatically flocked products is JIS L 1084 “Testing methods for flocked fabrics” only. This standard is stipulated for testing methods of fabrics such as fabrics and knitted fabrics with flocking and is evaluated using a friction tester. In this study, the validity of the flocking strength evaluation of electrostatically flocked products using a resin film was investigated. Focusing on the length of the flock, it was tested with products of 0.3 mm, 0.5 mm, 0.8 mm. As a result, it was only 0.3 mm that the flocking strength could be evaluated by the rubbing. Flocks caused the friction block to rise, or flocks between the wear and adhesion layer were seen to be smooth. From this fact, when evaluating the flocking strength of electrostatically flocked products using a friction tester, it was found that long flocks exhibit cushioning effect and apparently increase the evaluation value of flocking strength.

The purpose of this study was to classify criteria for selecting clothing and examine their characteristics by sex and age in a large-scale sample of 10,800 people aged 20 to 79 years. The cluster analysis results allowed classification of the criteria for selecting clothing into four types: i.e., “emphasizing personal taste, fashion, function, and social norms”, “emphasizing function and social norms,” “emphasizing personal taste and fashion,” and “indifferent” types. A chi-squared test showed significant differences by sex and age in the four criteria for selecting clothing. In terms of sex characteristics in the criteria for selecting clothing, men showed the highest proportion in “emphasizing function and social norms” and women showed the highest proportion in “emphasizing personal taste, fashion, function, and social norms.” In terms of age-specific characteristics, “emphasizing personal taste, fashion, function, and social norms”, “emphasizing personal taste and fashion,” and “emphasizing function and social norms” showed the highest proportions in men aged in their 20s, 30s, and 40s–70s, respectively. “Emphasizing personal taste, fashion, function, and social norms” showed the highest proportion in women in all age groups.
