一种人造羽绒及其制备装置和方法
By using uneven heating and cutting and sealing technology, artificial down with a three-dimensional core-like structure is formed, which solves the problem of two-dimensional planar structure caused by the reliance on heat-melting yarn in existing technologies, and improves fluffiness and warmth retention.

AI Technical Summary
Technical Problem
Existing methods for producing synthetic down rely on hot-melt yarn operations, resulting in down with a two-dimensional planar structure and insufficient loft, making it incomparable to natural down.
Method used
A non-uniform heating method is used to form a linear adhesive part, which is then solidified during the cooling process. Combined with cutting and end-sealing techniques, a three-dimensional linear core-like down structure is formed. Hollow and eccentric core-sheath fiber materials are used to improve loft.
Benefits of technology
It achieves a high-loft three-dimensional linear-core down-like structure, which improves the warmth and loft of artificial down, making it suitable for applications in the field of down filling.

Abstract
本发明提供一种人造羽绒及其制备装置和方法，所述人造羽绒是由许多朵人造羽绒纤维集合体构成的，所述人造羽绒纤维集合体是由线状羽核和羽枝构成的线核绒状结构，该方法包括：将纤维沿MD方向排布在线形加热区，对所述线形加热区进行不均匀加热，使所述线形加热区的各纤维之间相互热黏合后冷却固化，形成所述线状羽核；本发明采用了不均匀加热的方式，在线形加热区形成线形黏合部，然后在线形黏合部附近的特定位置裁切，从而实现在冷却过程中因线形黏合部不同时冷却固化而发生卷曲，形成与传统绒状、枝状结构的人造羽绒完全不同的线核绒状结构。
