Description

METHOD FOR PRODUCING FIBER FILL

The present invention relates to a method for producing a fiber cotton used as a cotton material of a garment of the kind shown in claim 1, a sleeping bag, a pillow and a futon.

The prior art cotton of polymeric fibers or filaments, either solid or very thin tubular fibers or filaments, tends to flatten after being blown into a garment, sleeping bag, pillow or duvet, and the volume of the fibers or filaments It is not retained, but it collapses into an inconsistent flat piece that is experienced like a product with a reduced volume.

 With respect to the background, the object of the present invention is to show a method for producing an improved cotton material for use in a pillow and a quilt, said to be a significantly improved cotton material which, Loses.

The method according to the present invention is characterized in that the fiber rope separates the fibers or filaments of the size of 200-2000 pcs into a relatively large number of fiber bundles or fiber cords and then passes through an adhesive or binding device such as an ultrasonic bonding head, The bundle is controlled by a binding head and at the same time a cutter or a scissor which shortens the filaments to about 6-20 mm is carried out after the point-shaped bonding or binding of the filaments at intervals of -20 mm, It is packed in a blanket or used as a cotton pad for immediate injection into a pillow or blanket.

Surprisingly, the polymeric, artificial fiber fluff produced in this way is considered to appear as a significantly improved cotton material that can maintain good cotton ability and return to its original state in continuous blowing.

The method according to the invention is suitably carried out in the same way as using tubular filaments or fibers having 1-9 holes and a fiber thickness of 0.9-30 dtx, preferably about 0.9-7 dtx.

The method according to the invention can also be carried out in the same way as using solid filaments or fibers having a fiber thickness of 0.9-30 dtx, preferably about 0.9-7 dtx.

The invention is explained in more detail below with reference to the figures:
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a sketch of an embodiment of a fairly simple installation according to the invention for openings / diffusion polymeric fibers or filaments;
Fig. 2 shows a drawing of an embodiment of a burner having a plurality of twisted tubes with internal grooves;
Figure 3 shows a much enlarged view of some finished fiber fluffs; And
Fig. 4 shows a system of curved rods for diffusing fiber ropes of, for example, 200-2000 fibers or filaments into fiber bundles.

Figure 1 shows a schematic view of a fiber rope (3) fed from a cardboard packaging material containing about 40 kg of fiber ropes (3) of 30,000-80,000 fibers or filaments having a thickness of 0.9-30 dtx Figure 2 shows a simple facility (2).

The pulling rollers 4 on the left side of Figure 1 allow the fiber rope 3 to be pulled out of the cardboard packaging material and to be curved for the purpose of diffusing the fiber rope 3 into a wide fabric 8 (Figure 4) Is moved over the system of the rods 6 and then moved to the face machine 12 having a plurality of teeth 14 (only four are shown in Fig. 2) through the rollers 10.

The teeth 14 divide the textile fabric 8 into fiber bundles each containing 200-2000 fibers corrugated in a rounded tube 16 with a pointed end at the inlet opening 13 and a diameter of about 1 mm To the outlet (15).

Indicated that the circular tube 16 shown could have any desired transverse shape-four edges or polygons, in general.

That is, the embodiment shown with respect to the stuffing machine 12 is connected to the circular tube 16, which has a length of about 50-70 mm in the direction of movement of the fiber rope 3 and has a reduced diameter and the fiber rope 3 And has an internal groove toward the outlet 15 to exit the circular tube 16 as a very thinly entangled fiber rope 3.

The illustrated insertion opening 13 is funnel-shaped and the fiber rope 3 is immediately compressed before being further entangled with a twist, i. E., 3-4 twists per centimeter, for example, in a passage through the groove of the circular tube towards the central outlet 15. [ do.

The twisted fiber bundle is moved from the outlet 15 to the fiber cord through an adhesive or spot binding device, such as an ultrasonic binding device, whereby the point-like binding or binding is carried out with an angle of about 6-20 mm Lt; / RTI > bundle.

The cord or fiber bundle then passes through a cutting device 20 (a knife or a scissor) which cuts the fiber bundle into actual fiber downfill 22 of about 6-20 mm length, Respectively.

The fiber fleece 22 thus formed will be corrugated in a tight fashion and subsequently blown into the comforter or pillow at a later time so that the fiber fleece 22 will be "open up" and the point-like binding is similar to the pointed end of the fluffy Will result in obtaining a final shape very similar to natural fluff.

The fiber fleece 22 thus produced may be any one of those wrapped in a shipping bag or used to directly blow into a pillow or a bed when it occurs in connection with the blowing in itself of the 'open-up' of the fiber fluff; In other words, the resulting polymeric fiber fleece 22 will have a noticeably small volume until it "experiences" the first blowing operation, after which the fiber fleece 22 will provide a large volume corresponding to natural fuzing do.

Decitex is indeed an indicator of fiber titer, as dtx is the weight of a fiber or filament of 10,000 m, or 9 dtx, which is 10,000 m of 9 g of fiber weight.
