Synthesis Of Modified Polyacrylate Size And Study On Its Application Properties For Single Yarn Of Ramie

In this paper the industry of ramie weaving and conditions of applying size were analyzed and the new modified polyacrylate size was applied to substitute for PVA and starch size. The modified polyacrylate size was designed and synthesized according to the properties of single ramie yam. The thoughts, craft, method of synthesize were provided, and the synthesized size was tested on sizing of ramie. The properties of the modified polyacrylate size and its applied properties on ramie were measured, such as breaking strength, breaking extension and desizing percent of sizing yarn, tensile stress, thickness, water-solubility and abrasion resistance of size film. Compared with other sizes, the adhesivity, chemical stability, the properties of size films, and the quality of sizing yam were measured and analyzed. The resulted showed that appropriate size can be obtained by adjusted the material, proportion of monomers of acrylate copolymerization and the modified polyacrylate size was more suitable for sizing ramie than other conventional sizes. The modified polyacrylate size was a direction in sizing ramie yam development, which can improve the strength of ramie yarn , the percent of sizing and the efficiency of ramie products weaving.
