摘　　要：对T/C 50/50 13tex经纱通过采用不同浆料配方上浆,测试分析了温度28℃时不同湿度下上浆纱的吸湿与放湿规律,以及不同回潮率下上浆纱的断裂强力和耐磨次数。结果表明,不同配方下上浆纱的吸湿放湿规律相似,同种配方下回潮率对上浆纱断裂强力和耐磨次数的影响规律类似。配方1#上浆纱在一定平衡回潮率范围的断裂强力和耐磨性呈递减规律,平衡回潮率在4.26%时上浆纱的断裂强力和耐磨性最好;配方2#上浆纱在一定平衡回潮率范围的断裂强力和耐磨性呈递减规律,平衡回潮率在4.65%时上浆纱的断裂强力和耐磨性最好。The sizing of T/C 50/50 13 tex warp yarn were carried out by using different slurry formula.The moisture absorption and liberation regularities of sizing yarn at 28℃ and the breaking strength and wear resistance of sizing yarn under different moisture regain were measured.The results showed that the moisture absorption and liberation regularities of the sizing yarn under different formula were similar.The influences of the moisture regain on the breaking strength and wear resistance of the sizing yarn under the same formula were similar.The breaking strength and wear resistance of 1#sizing yarn reduced in certain equilibrium moisture regain range.The breaking strength and wear resistance of the sizing yarn were best when the equilibrium moisture regain was 4.26%.The breaking strength and wear resistance of 2#sizing yarn reduced in certain equilibrium regain range.The breaking strength and wear resistance of the sizing yarn were best when the equilibrium moisture regain was 4.65%.
