Abstract

A shaping-material or filler for textiles such as bedspreads, garments or the like is disclosed consisting of a large number of fiber aggregates of a maximum length of 50 mm each. The fiber aggregates are smaller and softer than down in nature and essentially all the fibers are crimped with the fibers of the individual fiber aggregates being arranged randomly inside each aggregate. A filler is created thereby which is especially suitable for textiles such as bedspreads, or garments such as jackets, coats or the like with, the filler being enclosed in an envelope. This filler can be made to vary in thickness with surface distribution, in the manner known for fiber balls and down. However, the filler has little shift, even if the textile is vigorously shaken, and nevertheless, is very soft. A method for manufacturing the textile is also described.

Claims

1. Fiber aggregates for use as fillers for textiles such as bedspreads, garments or the like comprising:

individual fiber aggregates having a maximum length of 50 mm, the fiber aggregates being smaller and softer than down, in that essentially all fibers are crimped and wherein the fibers of each individual fiber aggregate are randomly arranged therein and the fibers consist of a mixture of fine and coarse fibers.

2. Fiber aggregates as defined in claim 1, characterized in that the fibers inside the individual aggregates are arranged randomly but are arranged spherically in an outer layer of each fiber aggregate.

3. Fiber aggregates as defined claim 1, characterized in that the fibers and fiber ends in the outer layer of the individual fiber aggregates are spherically wound.

4. Fiber aggregates as defined in claim 1, characterized in that the fiber aggregate evinces intrinsic internal cohesion.

5. Fiber aggregates as defined in claim 4, further including binding fibers affixed to fibers of this aggregate to enhance the intrinsic, internal cohesion.

6. Fiber aggregates as defined in claim 1, characterized in that each fiber-aggregate length is a maximum of 15 mm, but preferably between 4 and 10 mm, and in that the fibers of the fiber aggregate are in the range of 30 to 60 mm long.

7. Fiber aggregates as defined in claim 1, characterized in that the proportion of the coarse fibers in the fiber mixture is in the range of 2 to 20%.

8. Fiber aggregates as defined in claim 1, characterized in that the fibers in the fiber aggregate are synthetic fibers.

9. Fiber aggregates as defined claim 1, characterized in that the fibers in the fiber aggregate are animal hairs.

10. Fiber aggregates as defined in claim 9, characterized in that the animal-hair fibers in the fiber aggregate include underhair and long, coarse hair, the long, coarse hair being artificially crimped.

11. A shaping-material or filler for textiles such as bedspreads, garments or the like, and consisting of a large number of fiber aggregates defined in claim 1, the maximum length of the individual fiber aggregate being 50 mm, characterized in that

the fiber aggregates of the shaping-material or filler evince mutual cohesion.

12. A shaping-material or filler as defined in claim 11, characterized in that the fiber aggregates are bonded together by binding fibers.

13. Textiles such as bedspreads, garments or the like, with a filler defined in claim 11 and consisting of a large number of fiber aggregates and held in an envelope.
