Definitions
- the invention relates to a splittable yarn, fiber or filament, a process for their production and a device.
- JP 07/026454 and US Pat. No. 5,899,785 disclose splittable yarns, fibers or filaments which consist of at least two types of polymer which tend to separate phases from one another. Polyamides and polyesters are preferably used for this purpose.
- the weight ratio of the polymers used to one another can only be varied in a ratio of 30:70 to 70:30, since otherwise no separate polymer segments are obtained and splitting into microfibers or filaments is therefore impossible.
- those are required which are easy to manufacture with regard to the percentage composition of the polymers used and the fineness, the filaments contained in them and with regard to the necessary changes to the device are easy to use.
- the object is achieved by splittable yarns, fibers or filaments which consist of at least two filaments of a polymer A, with every second filament being partially coated with the polymer B at least to the extent that the surface of the splittable yarn, fiber or filament alternating sections of the polymers A, B.
- the splittable yarns, fibers or filaments according to the invention permit a reduction in the proportion of polymer B to 5 to 25% by weight and thus the production of a largely polymer-uniform product. This results in advantages in terms of mechanical properties, reusability and reductions in material costs.
- the splittable yarns, fibers or filaments according to the invention are suitable especially for the production of textile fabrics, knitted fabrics or nonwovens.
- the remaining elementary threads are preferably coated with a pigment-dyed mass of polymer A, whereby color-fast products are obtained which show only slight changes in their mechanical properties compared to the undyed products, since only 1 to 15% by weight, preferably 2 to 12% by weight.
- % of the elementary fiber can be used as a colored sheathing component (master batch).
- They preferably have a round, oval, flat, tubular or cruciform cross section, so that they can meet different requirements.
- the process according to the invention for producing the splittable yarns, fibers or filaments takes place in such a way that the polymers A and B are introduced into a spinning head in molten form, distributed into groups of filaments, every second filament covered with the polymer B, in spinnerets to form the splittable yarns , Fibers or filaments are combined and subsequently drawn.
- the remaining filaments are preferably coated with a pigment-colored mass of polymer A.
- the groups of filaments are pressed through spinnerets with round, oval, rectangular, ring segment or cross-shaped outlet openings.
- the stretchable yarns, fibers or filaments are drawn in a pneumatic drawing process.
- the known mechanical stretching processes such as godet stretching are possible as alternative methods.
- the splittable yarns, fibers or filaments are produced in the device according to the invention by means of a melt spinning process using at least two mutually incompatible polymers, in which they are introduced into a modular spinning head which consists of a first distributor plate which has alternately arranged distributor channels and which has openings to a second distributor plate, the alternatingly arranged distribution channels of the second distributor plate running approximately at a 90 ° angle to the distribution channels of the first distributor plate and having openings which supplies a third distributor plate with polymer and which connects the second distributor plate to a first Represents outlet plate for the filaments, wherein the third distributor plate has sub-distribution channels which extend over its entire thickness and the ends of which with the number of outlet openings for Elementary threads correspond, and that this is followed by a fourth distributor plate, the sub-distributor channels of which likewise extend over its entire thickness and which allow at least a partial covering of every second elementary thread to be followed by a second outlet plate, the outlet openings for the elementary threads of which are arranged in groups
- the modularly constructed spinning head according to the invention can be varied in a simple manner by exchanging the distributor plates and / or the outlet plates with regard to the number or quantity of the filaments contained in the splittable yarns, fibers or filaments.
- an almost polymer-uniform yet splittable can Fiber, filament or yarn are produced because the necessary polymer B, which is incompatible with polymer A, only surrounds every second filament made of polymer A as a separating sheath.
- An asymmetrical sheathing ie an uneven wall thickness of the sheathing or an incomplete sheathing, can also cause a tendency to crimp the split filaments.
- sub-distribution channels which extend over the entire thickness of the distributor plate, ensure good throughput of the polymers through the spinning head and simplified cleaning.
- the device according to the invention is one in which a fifth distributor plate is arranged between the fourth distributor plate and the second outlet plate, the sub-distributor channels of which also extend over their entire thickness and which allow the sheathing of the remaining filaments, the polymer C being drilled through holes in the third and fourth distributor plate and the first outlet plate is routed to the fifth distributor plate.
- the remaining elementary filaments are preferably coated with a spun-dyed mass of the polymer forming the core, since this allows the color fastness of the products to be increased in a simple manner without the mechanical properties of the fibers, filaments or yarns being significantly impaired by the addition of the pigments.
- a further advantageous embodiment of the device is that the sub-distribution channels of the third distribution plate for the polymer A supply the outlet openings of the first outlet plate arranged in a circle with polymer, and that the polymer B through an opening arranged centrally through the third distribution plate and the first outlet plate is routed to the fourth distributor plate and is brought to every second filament via the sub-distributor channels.
- a device is particularly preferred in which the outlet openings for the filaments in the groups of the outlet plate are arranged approximately circularly, a group comprising 6, 8, 12, 16, 24, 32 or 48 outlet openings.
- the fineness of the filaments can be varied with the number of filaments in a group, which are combined to form a splittable yarn, fiber or filament.
- the device is preferably also one in which the groups of outlet openings for the filaments are arranged approximately in concentric circles.
- the arrangement in concentric circles ensures, on the one hand, a favorable inflow of cooling air and, on the other hand, a combination of all splittable yarns, fibers or filaments emerging from a spinning head into a common drawing device.
- the device is preferably also one in which the diameters of the outlet openings for the filaments are in the range from 0.15 mm to 0.9 mm.
- a device in which the outlet openings for the polymers have different diameters is particularly preferred. Due to the different dimensioning of the diameters for the outlet openings, the ratio of the polymers in a splittable yarn, fiber or filament can be designed differently.
- the corresponding distances have proven to be favorable with regard to the use of space and the stability of the second distributor plates.
- the device is advantageously characterized in that the ends of the sub-distribution channels of the second distribution plate are branched in a V-shape.
- a corresponding design of the sub-distribution channels leads to a very favorable use of the space without fluidic disadvantages.
- the device according to the invention is characterized in that the first distributor plate, the second distributor plate and the outlet plate are directly connected to one another and centered by bolts or screws penetrating their edge without seals or sealing compounds.
- the connection according to the invention of the first distributor plate to the second distributor plate and the outlet plate ensures a tight assembly of the modular spinning head, without the need for seals or sealing compounds.
- the distributor plates three, four and five according to the invention and the outlet plates one and two consist of metal sheets with a thickness of 0.2 to 2.5 mm, preferably 0.5 to 1.5 mm.
- the method according to the invention for the production of yarns, fibers or filaments is characterized in that by using the second distributor plate with sub-distributor channels of 6, 8, 12, 16, 24, 32 or 48 outlet openings, the number of filaments of the splittable yarns, fibers or filaments is varied. In a very economical way, the production of splitable possible yarns, fibers or filaments from the appropriate number of filaments.
- the process for producing splittable yarns, fibers or filaments is preferably carried out in such a way that the mass ratio of the polymers A to B is varied by exchanging the outlet plate by using an outlet plate with different diameters of the outlet openings for the polymers. This allows the composition ratio of the splittable yarns, fibers or filaments to be set in a wide range. Furthermore, by using the fifth distributor plate, two differently coated elementary threads can be produced.
- the fifth distributor plate is preferably coated with colored polymer.
