The objective of this work was to examine the influence of poly (2-acryloylamino-2-methyl-1-propanesulfonic acid) (PAMPS) branches grafted onto starch molecules upon viscosity stability, adhesion and desizability of corn starch for warp sizing. A series of starch-g-PAMPS samples with different grafting ratios were prepared by graft copolymerization of acid-converted starch (ACS) with different amounts of 2-acryloylamino-2-methyl-1-propanesulfonic acid (AMPS), respectively, in an aqueous medium. The influence of the grafted PAMPS branches on the adhesion of starch to cotton and viscose fibers was evaluated by measuring the bonding forces of slightly sized cotton and viscose roving and comparing the adhesion of starch-g-PAMPS samples with that of ACS, according to a legal method (FZ/T 15001–2008). Their influences on viscosity stability and desizability were also evaluated. The desizability was investigated by measuring the time required for breakage of the film in hot water. It was found that starch-g-PAMPS samples were superior to ACS in adhesion to both fibers, viscosity stability and desizability, indicating that the PAMPS branches introduced were able to improve adhesion to the fibers, viscosity stability and desizability of starch. With the rise in grafting ratio, gradually improved bonding forces to both fibers, paste stability and desizability were exhibited. Starch-g-PAMPS showed potential for use as a new starch-based size in the warp sizing of cotton and viscose.

这项工作的目的是检查接枝到淀粉分子上的聚（2-丙烯酰氨基-2-甲基-1-丙磺酸）（PAMPS）支链对用于经纱施胶的玉米淀粉的粘度稳定性、粘附性和退浆性的影响。通过酸转化淀粉 (ACS) 与不同量的 2-丙烯酰氨基-2-甲基-1-丙磺酸 (AMPS) 的接枝共聚，制备了一系列不同接枝率的淀粉-g- PAMPS 样品。水性介质。对淀粉粘附到棉和粘胶纤维接枝PAMPS分支的影响通过测量略微尺寸棉粗纱和粘胶粘接力和比较的淀粉的粘合评价克-PAMPS 样品与 ACS 样品，根据法定方法 (FZ/T 15001–2008)。还评估了它们对粘度稳定性和退浆性的影响。通过测量薄膜在热水中破裂所需的时间来研究退浆性。发现淀粉-g- PAMPS样品在对两种纤维的粘附性、粘度稳定性和脱浆性方面均优于ACS，表明引入的PAMPS支链能够提高淀粉对纤维的粘附性、粘度稳定性和脱浆性。随着接枝率的增加，两种纤维的结合力、糊料稳定性和退浆性逐渐提高。淀粉摹-PAMPS显示用作经纱棉和粘胶的上浆新的淀粉基规模的潜力。
