摘　　要：探讨羧甲基纤维素纳米纤维复合聚丙烯酸酯乳液共聚浆料的上浆性能。采用羧甲基纤维素纳米纤维(CCNF)对聚丙烯酸酯乳液共聚浆料(NA)进行改性,制备了系列复合聚丙烯酸酯乳液共聚浆料(CNA),并对其溶液的流变性能与浆纱性能进行了探讨。研究结果表明:在CCNF用量占NA浆料固含量不大于3%时,NA浆料及CNA浆料的溶液均属于假塑性流体;随着CCNF含量的增加,CNA浆料的乳胶粒子直径呈递减趋势,而溶液表观黏度呈增加趋势。采用CNA浆料溶液对9.8 tex和7.4 tex纯棉纱上浆,在上浆率明显降低的情况下,CNA浆料溶液的各项浆纱性能依然优于工厂实际浆纱生产配方,其中,当CCNF用量占NA浆料固含量为1.5%时,所制备的CNA浆料的综合浆纱性能最佳。认为:CNA浆料具有调浆简单、上浆率低、浆纱性能优异及退浆废水易于治理的特点。Sizing property of carboxymethyl cellulose nanofiber composite polyacrylate lotion copolymerization size were discussed.A series of nanocomposite polyacrylate emulsion copolymer size CNA was prepared by modifying polyacrylate emulsion copolymer slurry(NA)with carboxymethylcellulose nanofibers(CCNF).The rheological property and sizing performance of the solution were discussed.Study results showed that,within the range amount of CCNF accounted for less than 3%of the solid content of NA size,the solution of NA size and CNA slurry were pseudoplastic fluids.With the increase of CCNF content,the latex particle diameter of CNA slurry showed a decreasing trend,while the apparent viscosity of the solution was increased.Using CNA slurry solution for 9.8 tex and 7.4 tex cotton yarn,under the condition that the sizing percentage was significantly reduced,the sizing performance of CNA slurry solution was still better than the actual sizing production formula of the factory,when the CCNF dosage accounts was 1.5%of the solid content of NA slurry,the comprehensive sizing performance of the prepared CNA slurry was the best.It is considered that CNA slurry has the characteristics of simple pulping,low sizing percentage,excellent sizing performance and easy treatment of desizing wastewater.
