Embodiment Construction

[0040] Figure 1 shows a part of a filled product according to the invention. The product mainly consists of feathers 1 bound in a structure formed by fibers 2 .

[0041] As will be described in detail later, the fibers 2 are first mixed with the feather 1, and the combination is then subjected to a heat treatment operation that bonds the structural fibers 2 together.

[0042] The word "feather" refers to ordinary feathers, small feathers or down or a mixture of these different products. The weight of feathers in the stuffed product ranges from 10 to 80%, preferably from 30 to 60%. The rest mainly consists of structural fibers 2 as will be described in detail below.

[0043]A structural fiber 2 is shown in FIG. 2 . This fiber is of the bicomponent type. Its central component or core 3 consists of fibers made of polymer material with a high softening point above the heat treatment temperature of the feather-fibre mixture, ie for example above 200°C. The other components on ...

Abstract

The invention concerns a feather-based padding product having a coherent shape resulting from the presence of a structure in the form of a three-dimensional network; said network consists of mutually bound thermoplastic fibres (2), which enclose said feathers. Said fibres (2) are first mixed with the feathers, then with appropriate heat treatment, said fibres are bonded at their contact points (5). The padding product is thus in the form of a web and it is packed in rolls or in the form of slabs.

Description

technical field [0001] The invention relates to a stuffed product whose basic material consists of feathers; it also relates to a method for producing such a product and a device for carrying out the method. Background technique [0002] Feather based filling products are used in various industries due to their performance and quality. [0003] They can be used in bedding, furniture, clothing, but also in other areas for padding (padding) and / or insulation. [0004] This material consists of feathers, but usually consists of feathers, feathered items, flakes and / or down, depending on the application. The material is usually loose and difficult to fill. Its characteristics are actually close to the characteristics of light dust materials, that is, amorphous and easily scattered. [0005] As described in documents WO9206916 and WO0056971, proposals have been made to control this material in order to improve its filling. [0006] In these documents, it is proposed that when...
