鴨(ya)(ya)(ya)絨(rong)是(shi)長(chang)在鴨(ya)(ya)(ya)的腹部(bu)，成蘆花朵狀(zhuang)的絨(rong)毛(mao)，成片狀(zhuang)的叫羽毛(mao)。一(yi)般(ban)國產(chan)鴨(ya)(ya)(ya)絨(rong)的膨(peng)脹度在450左(zuo)右，國產(chan)鵝絨(rong)的膨(peng)脹度從(cong)450到600，因(yin)為鴨(ya)(ya)(ya)絨(rong)是(shi)保(bao)溫性較好(hao)的商品，包裝過緊，不(bu)(bu)但不(bu)(bu)容(rong)易散熱，而(er)且容(rong)易產(chan)生(sheng)水蒸氣(qi)，不(bu)(bu)易保(bao)管；還可能(neng)使鴨(ya)(ya)(ya)絨(rong)變(bian)形，影(ying)響彈性。因(yin)為鴨(ya)(ya)(ya)有2種(zhong)毛(mao)，外面一(yi)層(ceng)是(shi)外羽，表層(ceng)有一(yi)層(ceng)油脂(zhi)防止鴨(ya)(ya)(ya)子下水時里(li)面羽毛(mao)不(bu)(bu)會被水打濕，還有保(bao)護作(zuo)用。保(bao)暖主要來(lai)自細絨(rong)。

蓬(peng)松度(du)是(shi)(shi)體(ti)現羽(yu)絨(rong)(rong)(rong)品(pin)質的關鍵指標，羽(yu)絨(rong)(rong)(rong)制品(pin)主要是(shi)(shi)看蓬(peng)松效果，即是(shi)(shi)膨脹的程(cheng)度(du)；這(zhe)就(jiu)(jiu)注定了羽(yu)絨(rong)(rong)(rong)是(shi)(shi)應以體(ti)積衡量而不是(shi)(shi)重量。鴨(ya)(ya)(ya)絨(rong)(rong)(rong)就(jiu)(jiu)是(shi)(shi)加工過的鴨(ya)(ya)(ya)氄毛，有(you)很強的保暖(nuan)(nuan)能力。羽(yu)絨(rong)(rong)(rong)又分為鴨(ya)(ya)(ya)絨(rong)(rong)(rong)和(he) 鵝(e)絨(rong)(rong)(rong)，同等條件(jian)下鵝(e)絨(rong)(rong)(rong)的保暖(nuan)(nuan)程(cheng)度(du)稍高于(yu)鴨(ya)(ya)(ya)絨(rong)(rong)(rong)。羽(yu)絨(rong)(rong)(rong)產品(pin)填(tian)充又主要分為白鵝(e)絨(rong)(rong)(rong)、灰鵝(e)絨(rong)(rong)(rong)、白鴨(ya)(ya)(ya)絨(rong)(rong)(rong)、灰鴨(ya)(ya)(ya)絨(rong)(rong)(rong)、鵝(e)鴨(ya)(ya)(ya)混合(he)絨(rong)(rong)(rong)和(he)粉碎絨(rong)(rong)(rong)。就(jiu)(jiu)保暖(nuan)(nuan)來(lai)講，鵝(e)絨(rong)(rong)(rong)要好于(yu)鴨(ya)(ya)(ya)絨(rong)(rong)(rong)。

鴨(ya)(ya)(ya)(ya)絨比較保(bao)暖，一般(ban)來講鵝絨纖維的(de)(de)(de)體(ti)積要(yao)大(da)于鴨(ya)(ya)(ya)(ya)絨纖維，固(gu)定空氣量也(ye)大(da)于鴨(ya)(ya)(ya)(ya)絨纖維，白(bai)鴨(ya)(ya)(ya)(ya)絨，所(suo)以(yi)自然比鴨(ya)(ya)(ya)(ya)絨保(bao)暖。里面的(de)(de)(de)叫鴨(ya)(ya)(ya)(ya)絨，主要(yao)起保(bao)溫作用，它們細而密，還(huan)很輕，使(shi)冷空氣很難進(jin)入，體(ti)溫自然就不會流失(shi)，所(suo)以(yi)很保(bao)暖。鴨(ya)(ya)(ya)(ya)絨是長在鴨(ya)(ya)(ya)(ya)的(de)(de)(de)腹(fu)部(bu)，成(cheng)蘆(lu)花朵狀的(de)(de)(de)絨毛，成(cheng)片狀的(de)(de)(de)叫羽(yu)毛。一般(ban)國產(chan)鴨(ya)(ya)(ya)(ya)絨的(de)(de)(de)膨(peng)脹度在450左右，國產(chan)鵝絨的(de)(de)(de)膨(peng)脹度從(cong)450到(dao)600，
