The utility model relates to an elastic breathable, breathable and perforated medical bandage that combines the surface layer non-woven fabric and the bottom nonwoven fabric in a stretch state without the need of hot pressing and nonwoven fabric. The film has a number of holes in the film surface of the elastic film and has a lot of holes with a lot of holes. The elastic membrane is elastic and breathable medical bandage after the elastic film is combined with the surface layer non-woven fabric and the bottom non-woven fabric, and the elastic and breathable medical bandage has many through holes in the stretch state. Advantages: first, without hot melt adhesive, it can realize the composite of surface layer non-woven fabric, bottom non-woven fabric and elastic film, and ensure the air permeability of elastic film and non-woven fabric itself is not affected by hot melt adhesive. Two is the design of opening elastic film, which not only makes the tensile rate of the elastic film greatly increased, but also has high elastic and large stretch rate. Three, good elasticity, good flatness and good air permeability.

彈性透氣打孔醫(yī)用繃帶
本技術(shù)涉及一種既無需熱壓膠,也無需拉伸無紡布,便能將面層無紡布和底層無紡布復(fù)合在拉伸狀態(tài)下彈性透氣膜兩面且二次打孔成型的彈性透氣打孔醫(yī)用繃帶,屬醫(yī)用繃帶制造領(lǐng)域。
技術(shù)介紹
CN103417331A、名稱“加厚無紡布彈性繃帶及制備方法”,包含上下四層無紡布,上兩層無紡布之間通過醫(yī)用壓敏膠點(diǎn)涂復(fù)合形成上雙層無紡布,下兩層無紡布之間通過醫(yī)用壓敏膠點(diǎn)涂復(fù)合形成下雙層無紡布,上雙層無紡布與下雙層無紡布之間通過醫(yī)用壓敏膠點(diǎn)涂復(fù)合且中間夾有氨綸絲層,并通過熱壓壓點(diǎn)復(fù)合方式在布面形成有均勻的壓點(diǎn)。其不足之處:一是彈性差;二是透氣性差。

技術(shù)介紹
中的不足之處,設(shè)計(jì)一種既無需熱壓膠,也無需拉伸無紡布,便能將面層無紡布和底層無紡布復(fù)合在拉伸狀態(tài)下彈性透氣膜兩面且二次打孔成型的彈性透氣打孔醫(yī)用繃帶。設(shè)計(jì)方案:為了實(shí)現(xiàn)上述設(shè)計(jì)目的。本技術(shù)在結(jié)構(gòu)設(shè)計(jì)上:1、彈性透氣膜的膜面有很多透氣孔的設(shè)計(jì),是本技術(shù)的技術(shù)特征之一。這樣設(shè)計(jì)的目的在于:由于本技術(shù)所述彈性透氣膜與無紡布的復(fù)合為無膠(無熱壓膠)復(fù)合,即彈性透氣膜的膜面與無紡布直接熱融復(fù)合。為此本技術(shù)將所成型的彈性流延膜面設(shè)計(jì)為開孔的彈性透氣膜面,這樣設(shè)計(jì)的目的在于:開孔彈性透氣膜面不僅能夠使本不透氣的彈性膜變成透氣膜,而且很多個(gè)透氣孔分布在彈性膜面使彈性膜面拉伸率則增大,從而實(shí)現(xiàn)了高彈力、大拉伸率的目的,所制的醫(yī)用繃帶具有平整度好、拉伸率大、彈性好、透氣性好且價(jià)格低。2、帶有很多透氣孔的彈性透氣膜在拉伸狀態(tài)下與面層無紡布和底層無紡布熱復(fù)合的設(shè)計(jì),是本技術(shù)的技術(shù)特征之二。這樣設(shè)計(jì)的目的在于:由于 ...
