| In recent years,there have been more and more badminton enthusiasts in domestic.Results of Research 1 show that 55%of 191 respondents have professional badminton activewear.Compared with aesthetics,66.7%respondents pay more attention to functionality of badminton activewear.Thus,it has broad prospects to develop the functional badminton sportswear.This paper studied consumers' demands and female upper body sweat distribution and intensity during playing badminton.Based on these results and combined with enterprise's actual situation,yarns and fabric structures were selected and used to knit fabric and badminton sportswear.Developed fabrics' properties were tested with instruments and comfort of new products and the functional sportswear bought from market acting as contrasts were assessed and compared by subjective evaluation method.It can not only evaluate the functionality of new products but also provide suggestion for the next development.Firstly,consumer's demands were researched with questionnaire I.Result of female research objects shows that the top four features they like are respectively good breathability,good moisture absorption and quick dry,move freely and good tactility.Secondly,using conjoint analysis to build models of badminton sportswear and then design questionnaire II to research targeted female customer's preference for these models.Finally,the preferred model is the product to be developed which is of good moisture absorption and quick dry,seamless,good breathability,good tactility,light color,tight and raglan sleeves.During the development process,sweat distribution and intensity of female upper body during playing badminton were studied through subjective evaluation and objective images.By analyzing data of this experiment,performance requirements of moisture absorption,breathability and thermal comfort for fabric of each part are proposed and can be divided into 5 types.It is the basis for sportswear's functional design,selection of yarns and structures.Three kinds of outer yarns(yarn S,yarn PA 66 and yarn Mica)and two kinds inner elastic yarns(30 S covering 20 spandex and 30 PA 66 covering 20 spandex)and four types seamless plating fabric structures were chosen.Totally 20 kinds of fabric and 4 types of badminton sportswear were developed.Among these fabrics some were dyeing and some were not.After dyeing and sewing,on one hand,fabric's moisture transfer performance(especially Liquid Moisture Management Properties),heat transfer performance and basic wearing performance were tested.It analyzed the impact of outer yarn,inner yarn and fabric structure on fabric wicking properties by using variance analysis.On the other hand,Comfort of new products and 2 pieces of badminton sportswear and one piece of seamless tight sportswear bought from market acting as contrasts were assessed and compared by subjective evaluation method.Results of MMT experiment show that fabrics of S/S with four plating structures have "Lotus effect" which is completely water repellent before moisture absorption and perspiration treatment.After treatment,they belong to wicking fabrics.Fabrics of P/P and C/P with biggest mesh plating structure are wicking before moisture absorption and perspiration treatment.As for fabrics of S/P,P/S and C/S with four seamless plating structures,bottom spreading speed are slow before treatment which belongs to wicking fabric after treatment.Among the 20 kinds of fabrics,the wicking property of fabric of S/P with small mesh plating structure is the best and is better than the two-layer wicking fabrics bought from market.Results of subjective evaluation experiment show that comfort and tactility of the new four products are better than the three products in the market chosen for comparison.It demonstrates that seamless knitting technology can be applied to knit functional activewear. |
