It is intended to provide a method for producing felt which can be used.

Since 1% by weight is mixed, the elastic action of the soft foam makes the felt lighter and more excellent in rebound resilience than a conventional felt consisting of only fibers. Further, the use of anti-hair fibers, that is, recovered fibers obtained by disintegrating a cloth material with an anti-hair machine and reducing it into a fibrous form, also enables reuse of the cloth material.

略に済む。Further, in the production method of the present invention, the soft foam can be finely mixed at the same time as the fibers are defibrated by the anti-hair machine, thereby simplifying the operation. In particular, for a composite material in which a cloth material and a soft foam are bonded or welded together, it is not necessary to separate the cloth material and the soft foam, and it is sufficient to use the anti-hair machine as it is, so the work is extremely simplified.

大きさになっている。First, the cloth material and the soft foam are subjected to an anti-hair machine using a garnet wire or the like, so that the hair of the cloth material and the soft foam are fragmented. Mix the foam strips. The cloth material used may be any of woven fabrics such as moquettes and plain weaves, or knitted fabrics such as tricots, double raschels, circular knits, etc., and the material of the fibers is not limited. On the other hand, as the flexible foam, a flexible urethane foam, a polyethylene foam, or the like is used. In addition, the soft foam formed into pieces by the anti-hair machine usually has a size of 2 mm or less.

が落ちる等、生産性低下にもつながる。The ratio of the cloth material and the soft foam to be applied to the anti-hair machine may be various ratios, and the mixing material used for the anti-hair is 80 to 98% by weight of the fiber component and 20 to 2% by weight of the soft foam component. So that This is because even if the ratio of the cloth material and the soft foam to be applied to the anti-hair machine is determined in advance, the soft foam partially becomes powder in the hair and accumulates at the lower part of the anti-hair machine and mixes with the anti-hair fiber. This is because the mixture of the cloth material and the soft foam which has been subjected to the anti-hair machine and the ratio of the soft foam cannot be obtained. If the soft foam component is less than 1% by weight in the thus obtained anti-hair mixture, the effect of improving the rebound resilience of the soft foam in the formed felt cannot be obtained. If the content is more than 15% by weight, the fibers are hardly entangled by the needle punch, and it is difficult to obtain a good felt. Furthermore, the resistance to the needle is increased by the soft foam, which may lead to breakage of the needle or a decrease in molding speed, leading to a decrease in productivity.

パンチ時に針が通りにくくなる恐れがある。The cloth material and the soft foam may be a laminated product in which at least a part thereof is laminated and integrated by adhesion or welding, or may include both the separated fabric material or the soft foam and at least one of the laminated products. It may be something. Adhesives or welds made by laminating a cloth material and a soft urethane foam into a laminate unit include adhesive laminate products and flame-welded (frame lamination) products used as skin materials for automobile seats or furniture seats. is there. It is preferable that the thickness of the soft foam of the laminated product is 10 mm or less. When the soft foam is thicker than 10 mm, the soft foam tends to have a large brim at the time of bristles, and there is a possibility that the needle may not pass easily during subsequent needle punching.

In that case, the mixing ratio of the cloth material having a long fiber length is a total of 100% of the cloth material and the soft foam of the laminate except the cloth material.

混入したものとなっている。Next, the mixture of anti-hair fibers and soft foam pieces formed by the anti-hair machine is formed into a fleece having a predetermined thickness by a conventional method. Entangling the body strips to form a felt of desired thickness. At this time, the higher the mixing ratio of the above-described fiber having a long fiber length, the more strongly the fiber becomes entangled felt. The felt is formed by needle punching using the same equipment and method as those used in normal felt formation. The obtained felt has a soft foam mixed therein.
