[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing anti-wool articles, and more particularly to a fibrous material having a low defibration rate or a fibrous material containing a synthetic resin foam backing layer, which has not been conventionally used as an anti-wool material. It relates to a method for producing anti-wool articles.

[0002]

2. Description of the Related Art Conventionally, it has been practiced to defibrate fiber materials such as used clothes, rags, and pieces of cloth to produce cotton-like anti-wool articles. The anti-wool product thus obtained is used for felt or the like.

Various kinds of fiber materials such as chemical fiber, cotton, wool, and hemp are used as the conventional anti-wool material, however, however, such as moquette having a short fiber length or tricot which is short and easy to be cut at the time of defibration. A fiber material having a low fineness was difficult to be defibrated and was not used as a fluff material.

In recent years, however, demands for recycling of resources have increased, and it has been desired to reuse fiber materials in as wide a range as possible. Further, for example, in automobile seats and the like, so-called frame laminated fiber products in which a synthetic resin foam layer is lined with a fibrous material such as a moquette are often used, but a backing layer of these synthetic resin foams is used. It is also an urgent task to recycle the textile products we have.
