麻/聚酯纤维混合针刺毡的制备与性能研究

Preparation and properties of bast fiber/polyester fiber blended needle punched felt

采用苎麻落麻、黄麻、聚酯纤维按照不同混合比例制备针刺毡,研究其透气性能、力学性能和热学性能。研究结果表明:黄麻/苎麻针刺毡均具有较好的透气性能,苎麻纤维的加人使得针刺毡的透气率大大下降,而黄麻纤维的加入能够提高苎麻和聚酯纤维针刺毡的透气率;麻纤维与聚酯纤维混合针刺毡的力学性能远远高于纯麻纤维针刺毡;不同比例针刺毡的热导率均较低,具有良好的保温性能;麻纤维的导热性能要优于聚酯纤维,纯苎麻针刺毡的热导率最高。

The needled felts are prepared by ramie noil, jute and polyester fiber to study their air permeability, mechanical properties and thermal properties tested. The result shows that the jute/ramie needled felts have good air permeability. The addition of ramie fiber could greatly reduce the permeability of needle felt, and the addition of jute fiber could improve the permeability of the needled felt of ramie and polyester fiber. The mechanical properties of hemp fiber mixed with polyester fiber needled felts are much higher than those of pure hemp fiber needled felts. The thermal conductivity of needled felts at different ratios are low, and they have good thermal insulation property. The thermal conductivity of hemp fiber is better than that of polyester fiber, and its insulation performance is better than that of pure ramie fiber.
