Polyethylene flash spinning non-woven fabric with uniform thickness

The invention relates to a polyethylene flash-spun non-woven fabric with uniform thickness. The gram weight of the polyethylene flash-spun non-woven fabric is greater than 50g/m < 2 >; the thickness of the polyethylene flash spinning non-woven fabric is 0.1 to 0.3 mm; the ratio of the area of the polyethylene flash-spun non-woven fabric with the thickness within the range of 0.15 mm and 0.2 mm to the area of the whole polyethylene flash-spun non-woven fabric is more than 60%; the moisture absorption expansion rate of the polyethylene flash spinning non-woven fabric when the relative humidity is 33%-84% is 0.5%-0.8%. The polyethylene flash non-woven fabric is uniform in texture and has a relatively good application prospect. 本发明涉及一种厚度均匀的聚乙烯闪纺无纺布，聚乙烯闪纺无纺布的克重为大于50g/m2；聚乙烯闪纺无纺布的厚度为0.1～0.3mm；厚度在(0.15mm,0.2mm]范围内的聚乙烯闪纺无纺布面积占全部聚乙烯闪纺无纺布面积的比值为60％以上；聚乙烯闪纺无纺布的相对湿度在33％～84％之间的吸湿膨胀率为0.5％～0.8％。本发明的聚乙烯闪蒸无纺布质地均匀，具有较好的应用前景。
