摘　　要：用透射电子显微镜(TEM)、纳米粒度仪、Zeta电位分析仪对透明状羧基聚硅氧烷乳液(CAS乳液)的粒径及其分布等物化性能进行测定,结果表明:CAS乳液的平均粒径为32.56 nm,Zeta电位为-28.35 mV.以棉纤维布样作载膜基质,使CAS乳液在基质表面固化成膜,再用扫描电镜(SEM)、接触角测定仪、电脑测控柔软度仪等对其成膜形貌、表面性能及应用进行研究.结果表明:CAS乳液具有良好的成膜性能,在棉纤维表面形成光滑平整的均一相薄膜,接触角为60.25°;经CAS乳液整理后织物的亲水性和白度较之未整理织物有所下降,柔软性能却显著提升,同时获得了独特的油润柔软手感.The particle size and the distribution of carboxyl-containing polysiloxane（CAS） emulsion with transparent appearance were measured by transmission electron microscope（TEM）,nano particle size analyzer and Zeta potentiometric analyzer.The results showed that the average particle size of CAS emulsion was 32.56 nm,while the ζ voltage is-28.35 mV.Taking the cotton fabric as the film forming substrate,CAS emulsion was anchored on the substrate surface to form film.The morphology,surface property and application of CAS emulsion film on cotton fabrics were studied by scanning electron microscope（SEM）,contact angle measurement and computer controlled softness instrument.The results indicated that CAS emulsion had good form-film property.The CAS emulsion could form an even,smooth and homogeneous film on the cotton fabric surface,with 60.25° of contact angle.Compared to untreated cotton fabric,the softness of treated fabric was obviously improved,while the hydrophilicity and whiteness were decreased.At the same time,the fabric treated with CAS emulsion acquired unique oily and soft handle.
