Description

Technical Field

[0001] This utility model relates to the field of 4D air fiber material processing technology, and in particular to a 4D air fiber material secondary forming device. Background Technology

[0002] 4D air fiber material is made from thermoplastic elastomers such as polyethylene (PE), polyolefin (POE), and TPEE, and is formed into a three-dimensional mesh structure through high-temperature melt spinning. 4D air fiber material is an ideal new material for making furniture such as mattresses, cushions, and pillows. However, current technology typically only allows for the production of simple structures such as square, cylindrical, and triangular shapes, and cannot produce complex curved shapes such as bone or bread shapes. If complex curved products are produced directly during fiber condensation, the process is demanding, the products are prone to collapse, resulting in significant material waste and increased production costs.
