This paper uses the production example of Apocynum & cotton blended yarn to verify and analysis the theoretical relationship between the limit unevenness of dual-component fiber blended yarn and the mixed fiber fineness and uneven.
用罗布麻/棉混纺的生产实例,验证分析了双组分纤维混纺纱的极限不匀与混合纤维细度及其不匀、混纺比之间的理论关系,证明所建立的成纱极限不匀理论关系式是可靠的,罗布麻纤维的含量选在小于25%对提高混纺纱强力和断裂伸长率,获得条干均匀的纱线比较有利。
Meanwhile L′Hospital rule of calculation for undefined limit is extended too.
通过一个定理的结论,给出L agrange、C auchy、积分中值定理和T ay lor公式的统一证明,同时得出计算不定型极限的L′Hosp ita l法则的推广定理。
