Abstract

A method for producing fibre fill for use as filling material in clothing, sleeping bags, pillows and duvets from a fibre rope (3) e.g. containing 30,000-80,000 fibres or filaments with a fibre thickness of 0.9-30 dtx, that the fibre rope (3) is divided into fibre bundles or fibre cords with a relatively large number of fibres or filaments of the magnitude 200-2000 pcs, determined by the dtx of the filaments, and then passing a gluing or welding unit (18), e.g. an ultrasound welding head, performing a punctiform gluing or welding together of the filaments, spaced apart about 6-20 mm, the bundles subsequently passing a cutter or scissors (20) which e.g. is/are controlled synchronously with the welding head (18) and which shortens the filaments into lengths of about 6-20 mm, after which the shortened fibre down (22) is either packed in shipping bales or are used directly for blowing into pillows or duvets as filling. Surprisingly it has appeared that the thus produced polymeric, artificial fibre downs appear as a very improved filling material which is capable of continuously maintaining a good filling capability and continuously returning to its original condition at the blowing.

Description

A kind of method of manufacturing fibrefill

Technical field

The present invention relates to a kind of method of manufacturing fibrefill, this fibrefill is used as the packing material in claim 1 pointed clothing, sleeping bag, pillow, eiderdown quilt and analog.

Background technology

The filling of polymer fiber or long filament in prior art, wherein this filler can be for three-dimensional or be made into very thin tubular fiber or long filament, there is the trend of the flattening of becoming,, after being blown into clothing, sleeping bag, pillow or eiderdown quilt, these fibers or long filament no longer keep its volume, but collapse becomes incoherent flat pieces, and this situation is just as experiencing the product of reduction volume.

Goal of the invention

Under this background, the object of the invention is to propose a kind of method of manufacturing follow-on packing material, this material is used for being blown into eiderdown quilt and pillow, and shows as a kind of packing material of significantly improveing, and can make this material keep recovering its reset condition in the time blowing.

Summary of the invention

The special feature of the method according to this invention is: fibrecord is divided into fibre bundle or filamental thread, this fibre bundle or filamental thread have quite a large amount of fibers or long filament, the order of magnitude is 200-2000 part (pcs), then by bonding or welding unit, as ultrasonic bonding head, long filament is about to the form spot bond of 6-20 millimeter (mm) or welds with spacing, fibre bundle pass through subsequently as with cutting machine or the scissors of plumb joint Synchronization Control, the length into about 6-20 millimeter (mm) sheared by long filament by this cutting machine or scissors, afterwards, the fibre fluff of cutting short is packaged in shipping bags, or be directly blown in pillow or eiderdown quilt as filler.

The polymer artificial fibre fluff of manufacturing thus shows wonderful effect as the packing material of improved significantly, and it can constantly keep good filling characteristic and can constantly return to its reset condition in the time blowing.

The method according to this invention is suitably to carry out by this way: employing has 1-9 hole and fibre number is tubular filaments or the fiber of 0.9-30 dtex (dtx), and preferably fibre number is about 0.9-7 dtex (dtx).

Or the method according to this invention can be carried out by this way: adopting fibre number is three-dimensional long filament or the fiber of 0.9-30 dtex (dtx), and preferably fibre number is about 0.9-7 dtex (dtx).

Brief description of the drawings

Below with reference to the accompanying drawings the present invention is set forth in more detail, wherein:

Fig. 1 shows according to the present invention and opens/launch the sketch of the embodiment of a kind of equipment of simplifying very much of polymer fiber or long filament;

Fig. 2 shows the schematic diagram in embodiment with the comb of some torque tube, and these torque tube have inner groovy;

Fig. 3 shows the enlarged drawing of some fibre fluffs of making; And

Fig. 4 shows the system of bent stick, for fibrecord being launched into the fibre bundle having as 200-2000 fiber or long filament.

Detailed description of the invention

Fig. 1 shows an equipment 2 of quite simplifying, for manufacturing polymer fiber fine hair from fibrecord 3, this fibrecord 3 is supplied by container of paperboard, the fibrecord 3 that this container of paperboard comprises heavily approximately 40 kilograms (kg), it has 30,000-80,000 fiber number is fiber or the long filament of 0.9-30 dtex (dtx).

By pulling the roller bearing 4 in Fig. 1 left side, make fibrecord 3 from container of paperboard, mention and move on on the system of bent stick 6 (Fig. 4), so that fibrecord 3 with fan out to broad cloth 8 (Fig. 4), this cloth 8 moves to the comb 12 with a large amount of teeth 14 (4 teeth are only shown in Fig. 2) by roller bearing 10.

Cloth 8 is divided into multiple fibre bundles by tooth 14, and each fibre bundle comprises, for example 200-2000 fiber, these fibril aggregations in pipe 16, from entrance 13 gradually tapered attenuate and towards the outlet 15 twistings ground motions of diameter 1 millimeter (mm).

It should be noted that shown pipe 16 can have required shape of cross section arbitrarily alternatively, as quadrangle or polygon.

In other words, in illustrated embodiment, combing 12 is connected with pipe 16 in such a way, wherein in the direction of motion of fibrecord 3, there is the length that is about 50-70 millimeter (mm), and there is the diameter reducing gradually, and towards the inner groovy that exports 15, thereby make fibrecord 3 leave pipe 16 with the fibrecord 3 of very thin mutual winding.

Shown insert port 13 is infundibulate and twisting, that is, fibrecord 3 being further wound around (for example, every centimetre twisting 3-4 time) before, its groove through pipe is compressed at once towards the passage place of central outlet 15.

The fibre bundle of twisting shifts out with the form of filamental thread from exporting 15, and it is by bonding or spot welding unit 18, and as, ultrasonic bonding unit, each fibre bundle carries out the bonding or welding of point-like with the spacing of about 6-20 millimeter (mm).

Afterwards, filamental thread or fibre bundle are passed to cutter unit 20 (pocket knife or scissors), this cutter unit 20 is the length into about 6-20 millimeter (mm) by fibre bundle cutting, becomes actual fibre fluff 22, as shown in Figure 3.

The fibre fluff 22 forming thus is still assembled for tight shape, this will cause subsequently, fibre fluff 22 is by after being blown into eiderdown quilt or pillow, will be as early as possible " opening " obtain its net shape, because point-like pad is similar to the tip of fine hair, so the net shape of fibre fluff and natural fine hair are very approximate.

The fibre fluff 22 of manufacturing thus can be packaged in transport bag or for being directly blown into eiderdown quilt or pillow, and in eiderdown quilt or pillow, fibre fluff " opening " is own relevant with air blowing; In other words, the polymer fiber fine hair 22 of manufacture has obviously less volume operation until its " experience " blows for the first time, and after blowing, fibre fluff 22 has larger volume, and this volume is equivalent to the volume of natural down.

Dtex is actually the instruction of fibre number (fiber number, titer), and because dtx is the weight in grams of fiber or the long filament of 10,000 meters, 9dtx refers to that the weight of the fiber of 10,000 meters is 9 grams.
