| 1 | 马来酸酐酯化预处理型PAA接枝淀粉浆料显示文摘通过对淀粉进行马来酸酐酯化预处理,在淀粉大分子上引入碳碳双键,再将这种含有碳碳双键的淀粉与丙烯酸单体进行接枝共聚合反应,以期大幅度提高淀粉与丙烯酸单体接枝共聚合反应的接枝效率,进一步提高接枝变性淀粉浆料的上浆性能。研究结果表明,当淀粉酯化取代度在0.0136-0.0412范围内,这种酯化预处理能使淀粉对丙烯酸的接枝效率提高10%-30%,并能显著改善接枝淀粉浆料对纤维的黏附性能以及浆膜性能。实验证实这种淀粉酯化预处理的酯化变性程度以取代度等于0.0136-0.0206为宜。 | 张龙秋 祝志峰 | 2008 | 纺织学报2008，29，10： | 10 |
| 2 | 无PVA上浆研究进展显示文摘概括当前国内外在取代PVA浆料方面取得的成果。论述了在浆纱生产中取代PVA浆料的必要性和复杂性,总结了国内外在取代PVA方面的主要做法。指出提高变性淀粉浆料的性能、改进浆纱工艺、采用新型浆纱设备、大量混用聚丙烯酸(酯)浆料、研发新型的纺织浆料及开发新型的浆料助剂都是取代PVA浆料的重要举措。 | 祝志峰 荣瑞萍 | 2011 | 棉纺织技术2011，39，2： | 10 |
| 3 | The Usability of Polyoxyethylene Stearate as Lubricant for Sizing Cotton Warp Yarns显示文摘The usability of polyoxyethylene stearate with 10 ethylene epoxides(POES 10) as lubricant in warp sizing was investigated for replacing sizing cream in order to prevent blockage of paste delivery tube.The influences of POES 10 and sizing cream upon the adhesion of starch to fibers and the performances of starch film were measured and compared.Then,the usability of POES 10 as lubricant was evaluated through the comparison between POES 10 and sizing cream in tensile behaviors,abrasion resistance,and hairiness of sized cotton yarns.The experimental observation demonstrates that the influence of POES 10 upon the adhesion is similar to that of sizing cream.POES 10 is superior to sizing cream in tensile strength and breaking elongation of starch film when mass content of lubricants is equal to or exceeds 2%.Incorporating POES 10 into starch makes starch film more resistant to wear.Furthermore,POES 10 is preferred to sizing cream in the increase in tensile strength,loss in elongation,and abrasion resistance of sized cotton yarns.Using POES 10 as lubricant in size formulation is favorable to the decrease of longer hairs on sized yarns.POES 10 exhibits potential use during cotton warp sizing for replacing sizing cream. | 祝志峰 孟娜 许冬生 | 2012 | Journal of Donghua University(English Edition)2012，29，2： | 0 |
| 4 | Study on the Preparation of Allyl-modified Starch in Isopropyl/Water Medium for Warp Sizing显示文摘A new method for the pretreatment of starch by etherification was developed to eliminate the problems of lower grafting efficiency associated with the preparation of starch graft copolymers as warp sizing agents.The etherification of starch with allyl chloride was investigated in order to effectively enhance the reaction efficiency.The technological variables of the reaction considered for evaluating the etherification included sodium hydroxide amount,water content in water-isopropyl alcohol medium,allyl chloride concentration,reaction temperature and reaction time.The experimental result demonstrated that the variables considered showed evident effect on the reaction efficiency.For the etherification,a condition of 20% for the water content,1.5:1 for the molar ratio of sodium hydroxide to allyl chloride,and at 30℃ under 24 h reaction is sufficient to retain the reaction efficiency above 50%.Furthermore,a contrast test demonstrated that the graft efficiency can be increased with the etherification pretreatment. | 李曼丽 祝志峰 张龙秋 | 2008 | Journal of Donghua University(English Edition)2008，25，4： | 0 |
