使用堿性洗滌劑(ji)，如(ru)果(guo)漂洗不凈，殘留(liu)的(de)洗滌劑(ji)會(hui)對羽絨(rong)服造成損(sun)害(hai)，并且容(rong)易在(zai)(zai)衣(yi)服表(biao)面留(liu)下(xia)白(bai)色痕跡(ji)，影響美觀。切勿使用強烈的(de)清洗劑(ji)、漂白(bai)劑(ji)和衣(yi)物(wu)柔(rou)順劑(ji)，清洗前可短時(shi)間浸泡(pao)，用軟刷輕輕刷凈領(ling)口(kou)(kou)、袖(xiu)口(kou)(kou)等易臟部(bu)位。如(ru)果(guo)用沒達到(dao)成熟期(qi)的(de)鴨(ya)子生產羽絨(rong)被，它的(de)氣味會(hui)更重，在(zai)(zai)天氣潮濕的(de)時(shi)候(hou)鴨(ya)絨(rong)被氣味也會(hui)變的(de)更重。羽絨(rong)中(zhong)灰鴨(ya)絨(rong)和白(bai)鴨(ya)絨(rong)的(de)區別(bie)顏色：白(bai)色和灰。

蓬松度是(shi)體(ti)現羽(yu)絨(rong)(rong)品(pin)質的(de)關鍵指標，羽(yu)絨(rong)(rong)制品(pin)主要是(shi)看蓬松效果，即是(shi)膨脹(zhang)的(de)程度；這就(jiu)注(zhu)定了羽(yu)絨(rong)(rong)是(shi)應以(yi)體(ti)積(ji)衡量而(er)不是(shi)重(zhong)量。羽(yu)絨(rong)(rong)單純作為一(yi)個(ge)保暖(nuan)材料，它(ta)的(de)經濟價值(zhi)遠遠高于其他保暖(nuan)材料。可吸收人(ren)體(ti)散發流動的(de)熱氣，隔絕(jue)外界(jie)冷空(kong)氣的(de)入。含(han)絨(rong)(rong)量，如(ru)80絨(rong)(rong)表示100重(zhong)量單位(wei)中絨(rong)(rong)的(de)含(han)量是(shi)80單位(wei)。鴨絨(rong)(rong)一(yi)般高含(han)絨(rong)(rong)量在85到90，鵝(e)絨(rong)(rong)的(de)含(han)絨(rong)(rong)量可達90到95；

由于(yu)羽(yu)絨(rong)(rong)(rong)是(shi)(shi)一種(zhong)動(dong)物(wu)性蛋白質纖(xian)維，球(qiu)狀纖(xian)維上密布千萬個三(san)角形的(de)(de)細小氣(qi)孔(kong)，能隨氣(qi)溫(wen)變化(hua)而收縮(suo)膨脹，產(chan)生調溫(wen)功能，含絨(rong)(rong)(rong)量就(jiu)是(shi)(shi)指羽(yu)絨(rong)(rong)(rong)中，羽(yu)絨(rong)(rong)(rong)占(zhan)填充(chong)物(wu)的(de)(de)百分(fen)比。一件羽(yu)絨(rong)(rong)(rong)服的(de)(de)含絨(rong)(rong)(rong)量是(shi)(shi)90%，附近鴨(ya)(ya)絨(rong)(rong)(rong)廠(chang)家(jia)批發，就(jiu)說明羽(yu)絨(rong)(rong)(rong)占(zhan)到填充(chong)物(wu)的(de)(de)90%，剩下10%是(shi)(shi)羽(yu)毛。如果(guo)說買(mai)鵝(e)絨(rong)(rong)(rong)買(mai)的(de)(de)是(shi)(shi)品位，那么買(mai)鴨(ya)(ya)絨(rong)(rong)(rong)買(mai)的(de)(de)就(jiu)是(shi)(shi)實惠，就(jiu)而言，鴨(ya)(ya)絨(rong)(rong)(rong)比鵝(e)絨(rong)(rong)(rong)更有競爭(zheng)優(you)勢。羽(yu)絨(rong)(rong)(rong)價格是(shi)(shi)根據(ju)品質決定(ding)的(de)(de)，
