针对咖啡碳长丝在织造过程中存在耐磨性差、集束性不足的问题，根据浆液的粘附机理和在喷水织机织造过程中的要求，按照"相似相容"原理，同时结合咖啡碳长丝结构特点，设计了适于咖啡碳长丝浆丝聚丙烯酸酯浆料的结构及合成工艺，采用乳液聚合法合成了咖啡碳长丝浆丝用聚丙烯酸酯浆料。浆料性能测试结果表明，当单体质量比m（MAA）：m（MMA）：m（BA）=10：50：40时，合成的聚丙烯酸酯浆料对咖啡碳长丝的粘附性好、浆丝集束紧密。在小样浆纱机上进行咖啡碳长丝浆丝试验，浆丝性能测试表明，浆丝的集束性明显改善，耐磨性、强力明显增强。

There are problems of poor abrasion resistance and weak bundling property during the weaving of coffee carbon filament.A structure of polyacrylate size,which is suitable for sizing coffee carbon filament,is designed according to the adhere mechanism of size,the requirements in weaving process of water jet weaving machine and the principle of "similarity,compatibility".Emulsion polymerization process is adopted to synthesize polyacrylate size for sizing coffee carbon filament.The performance test shows that the prepared polyacrylate size has a good adhesion and bundling properties on coffee carbon filament when the mass ratio of MAA:MMA:BA is 10:50:40.The sizing practice is carried out on testing sizing machine and the results show that the abrasion resistance and the strength of the sized coffee carbon filament are improved obviously,the weave ability of coffee carbon filament can be enhanced effectively.
