家庭滚筒洗衣机洗涤温度对机织物外观平整性的影响

家庭滚筒洗衣机洗涤衣物时，水、洗涤温度的共同作用对织物外观平整性影响显著，合适的温度设定有助于洗衣机的参数优化。文中选取5种常见白色普通整理的机织物，在滚筒洗衣机温度分别为室温20、30、45、60、75 ℃条件下洗涤，测试其洗后外观平整度、洗涤前后弯曲刚度及剪切刚度等指标。研究发现，洗涤温度较低时，机织物外观平整度较好；洗涤温度增大时，机织物平整度降低，洗后弯曲刚度及剪切刚度减小。纯棉织物20℃与75℃洗后的平整度最大差值为1.6级；涤纶织物20℃与75℃洗后的平整度最大差值为3.8级，洗涤温度对涤纶织物平整度的影响较棉织物大。研究成果可为机织物家庭滚筒洗涤温度的设置提供依据。

Effect of washing temperature on smoothness appearance of woven fabric during domestic tumble laundering

Abstract：The effect of water and temperature on smoothness appearance of woven is very significant during domestic tumble laundering. Thus the setting of temperature is very important for washing parameter optimization. This paper selected five kinds of white and ordinary finishing woven fabrics to wash in different temperature which are 20℃, 30℃, 45℃, 60℃, 75℃ respectively, and then measured smoothness appearance, shear stiffness and bending stiffness. It indicates that the smoothness appearance, shear stiffness and bending stiffness decease with the increase of washing temperature. The reducing scope of pure cotton fabric in smoothness appearance is 1.6 degree; the pure polyester fabric is 1.6 degree. So the effect of washing temperature on polyester is more significant comparing with cotton fabrics. The results provide basis for washing temperature setting of woven fabrics domestic tumble laundering.
