1，家(jia)用(yong)縫(feng)紉機包(bao)括有(you)電(dian)(dian)(dian)動(dong)(dong)和電(dian)(dian)(dian)子兩款，其中(zhong)電(dian)(dian)(dian)動(dong)(dong)款可自(zi)動(dong)(dong)穿線、鎖扣眼，功(gong)能相對較單一，不過輕便小巧，縫(feng)制(zhi)效果好，能滿足普(pu)通家(jia)庭(ting)縫(feng)紉需求。電(dian)(dian)(dian)子款內部安裝微電(dian)(dian)(dian)腦，有(you)自(zi)動(dong)(dong)剪線、繡(xiu)花、速度控(kong)制(zhi)等(deng)功(gong)能，更適合(he)對縫(feng)紉要求較高的家(jia)庭(ting)使(shi)用(yong)。

2，多(duo)(duo)功(gong)能(neng)(neng)縫(feng)紉(ren)機能(neng)(neng)夠(gou)提供多(duo)(duo)種縫(feng)紉(ren)針(zhen)跡，支持雙線(xian)雙向縫(feng)紉(ren)和鎖邊，縫(feng)紉(ren)速(su)度也可以自己控制，而(er)且按鍵操作也簡便(bian)智能(neng)(neng)，能(neng)(neng)滿足多(duo)(duo)種縫(feng)紉(ren)需求(qiu)。選擇時要看其(qi)配(pei)件，配(pei)件越(yue)多(duo)(duo)，相應(ying)的功(gong)能(neng)(neng)也就越(yue)全(quan)面。

3，包縫(feng)(feng)機(ji)主(zhu)要用(yong)來鎖邊(bian)，防止服裝(zhuang)縫(feng)(feng)頭起毛，常見(jian)的包縫(feng)(feng)機(ji)有單線(xian)和(he)多(duo)線(xian)包縫(feng)(feng)，單線(xian)線(xian)跡稀疏，多(duo)線(xian)線(xian)跡密，縫(feng)(feng)制(zhi)牢(lao)固。要根據縫(feng)(feng)制(zhi)品來選包縫(feng)(feng)機(ji)，如(ru)(ru)果縫(feng)(feng)制(zhi)毯子邊(bian)，單線(xian)包縫(feng)(feng)機(ji)即(ji)可(ke)；如(ru)(ru)果縫(feng)(feng)制(zhi)針(zhen)織服裝(zhuang)、外(wai)衣(yi)或(huo)肩(jian)袖(xiu)等摩擦較大(da)部位，就需要多(duo)線(xian)包縫(feng)(feng)機(ji)。
