摘　　要：为了探究木棉制品在面部油脂吸附中的应用,将木棉和棉纤维以5种不同的比例(0∶10、3∶7、5∶5、7∶3、10∶0)混合梳理成纤维网,通过三道水刺加固制成非织造布。测试并表征了这5种非织造布的表面形貌、孔径分布、表面润湿性、吸油性能和瞬间吸附性能,并与市面上现有的吸油面巾纸做了对比分析。结果表明:水刺不会破坏木棉的空腔结构,且5种样品均具有很好的疏水亲油性;当木棉/棉混合比为7/3时,非织造布的吸油倍率(31.28)和保油率(94.69%)最高,且油液主要会附着在纤维表面、纤维与纤维间隙及纤维空腔中;此外,当木棉与棉的混合比为5/5时,0.5 s内的平均吸附速率最大(1.569 g/s)。研究表明木棉/棉水刺非织造布具有很好的吸油保油性能,为后续开发绿色环保木棉基吸油面巾纸提供了一定的理论参考。The secretion of facial oil in the human body is increasing,while the existing facial tissues on the market are mostly made of flax pulp and polypropylene materials,and have the shortcomings of non-skin-friendliness,poor oil absorption effect and refractory degradation.This paper aimed to make full use of the large and medium cavity and natural skin-friendly characteristics of kapok,and to prepare green oil-absorbing facial tissues with excellent oil-absorbing performance via hydroentanglement by blending with cotton fibers.Firstly,the kapok and cotton fibers were prepared by the carding machine to prepare the fiber web in different proportions(0∶10,3∶7,5∶5,7∶3,10∶0).Then,the hydroentangled nonwovens were prepared by the front and back and three-way hydroentangled process with increasing pressure sequentially.The surface morphology and pore size distribution of the nonwovens were characterized by scanning electron microscopy and porous material analysis instrument.and the surface wettability of the nonwovens was analyzed by optical contact angle measuring instrument.Finally,the oil absorption and instantaneous adsorption properties of the nonwovens were also tested and characterized.A polarizing microscope was used to observe the morphological characteristics of the fiber after absorbing oil,and a comparative analysis was conducted with the oil-absorbing performance of existing oil-absorbing facial tissues on the market.As can be seen from the scanning electron microscope,cotton fibers and kapok fibers are evenly distributed in the nonwoven,and mechanical hydroentanglement will not destroy the large and medium cavity structure of kapok,which provides a good structural basis for its oil absorption.When the ratio of kapok to cotton is 7∶3,the pore size of the nonwovens ranges from 0-60.87μm,and its average pore size is the smallest(25.92μm).Furthermore,the pore size distribution curve has obvious peaks,and the overall pore size distribution is relatively uniform.The contact angle between the five nonw
