摘要：该课题所研究的是聚乙烯吡咯烷酮改性锦/丙交织面料的吸湿速干性。研究结果表明经过聚乙烯吡咯烷酮（PVP）整理的织物与未经过整理的原织物相比，织物的蒸发速率、滴水扩散时间明显增快，透湿量、芯吸高度明显增大，刚性、机械性能明显增强。而含PVP5%的织物与PVP10%的织物相比较，含PVP10%的织物的蒸发速率、滴水扩散时间更快，透湿量、芯吸高度更大，刚性、机械性能明显更强。因为纤维、纱线之间以及织物中都会有空隙存在，且这些孔隙存在于水（雨水）和水蒸气之间。根据孔隙自然扩散机理，织物具有转移水蒸气的能力。因此，经过整理的织物更容易让水分流通，由于PVP的整理，刚柔性增强，机械性能也随之增强。因此，经过聚乙烯吡咯烷酮（PVP）整理的织物的吸湿速干性能更加强。

Study on Moisture Absorbing and Quick Drying Properties of Nylon/Propylene Interwoven Fabric Modified by

Poly(N-vinylpyrrolidone)

Abstract: The moisture absorbing and quick drying properties of Nylon/Propylene interwoven fabric modified by poly(N-vinylpyrrolidone) (PVP) were investigated in present study. The results showed that the evaporation rate, dripping diffusion time, moisture penetration, core suck height, stiffness and mechanical properties of fabric after modification with PVP increased obviously in comparison with the original fabric. Moreover the evaporation rate, dripping diffusion time, moisture penetration, core suck height, stiffness and mechanical properties of fabric after modification with 10% PVP solution was higher than modification with 10% PVP solution. This because that there are interspaces in fiber, yarn and fabrics. Moreover these interspaces are existed in the water and vapor. Fabrics present the ability for transporting vapor according to the pore diffusion mechanism. As a result, fabrics after modification can transport vapor more easily than original fabrics. The stiffness and mechanical properties of fabrics increased after modification with PVP. It can be concluded that the moisture absorbing and quick drying properties of fabric were improved after modification with PVP.
