摘要

非织造产品设计是非织造材料与工程专业实践教学环节的核心内容，本实验设计了基于高分子熔融纺丝和溶液纺丝技术，利用纤维三维网络重构法制备多层梯度结构和多尺度孔径的吸声复合材料，探究制备工艺对吸声材料结构与性能的影响。区别于传统非织造产品设计课程仅对常规空气过滤用非织造产品进行简单复制与重复验证，本实验设计将纤维基多孔吸声材料前沿研究成果融入非织造专业综合实验教学，引入先进非织造复合材料成形技术，指导学生自主探索吸声材料的制备和性能优化，提升了课程的高阶性、创新性和挑战度。该实验教学项目让学生更直观并深入了解纤维基多孔吸声材料的吸声机理、关键因素、梯度结构和设计路径，实现了非织造理论知识与工程实践的有机融合，有利于提升学生解决复杂工程问题的工程实践能力，并培养了学生工程社会意识。

Abstract

Nonwoven product design is the core content of practical teaching of nonwoven materials and engineering major. Based on polymer melt spinning and solution spinning technologies

this experiment is designed to prepare the sound-absorbing composites with multilayered gradient structure and multi-scale pore size by fiber three-dimensional network reconstruction method

and the influence of the preparation process on the structure and sound-absorbing properties of the prepared materials was explored. Different from the traditional nonwoven product design course

which only carries out simple replication and repeated verification of nonwoven products used in conventional air filtration

this experimental design integrates the cutting-edge achievements of fiber-based porous sound-absorbing materials into the comprehensive experimental teaching of nonwoven major

introduces advanced forming technology of nonwoven composites

and guides students to independently explore the preparation and performance optimization of sound-absorbing materials. The high-order nature

innovativeness and challenge level of the course has been enhanced. This experimental teaching project could enable undergraduate students to have a more intuitive and in-depth understanding of the sound absorption mechanism

key factors

structure and design path of fiber-based porous sound-absorbing materials. This could also realize the organic integration of nonwoven theoretical knowledge and engineering practice

enhance students’ engineering practice ability to solve complex engineering problems

and cultivates students’ engineering social awareness.
