Definitions
- the present invention relates to a bicomponent fiber of the core sheath type with polyester as the core component and polyethylene as the sheath component, the core being arranged eccentrically and the fiber having a very soft feel and an intense latent crimp.
- polyester fibers Because of their balanced property profile, polyester fibers have become the most widely used synthetic fibers. In recent years in particular, numerous efforts have been made to develop polyester fibers with specific properties that go beyond them.
- polyester fibers Compared to fibers made of polyolefins such as polyethylene or polypropylene, polyester fibers have a harder grip with the same titer. In some areas of application, such as B. the textile hygiene products, diapers and sanitary napkins are mentioned here, this harder grip has a disadvantageous effect. This also applies to textile hygiene products such as corresponding nonwovens.
- the fibers described therein can be, inter alia, a core / sheath fiber with a polyester core and a sheath which consists of a mixture of a linear, low-density copolymer of ethylene and at least one alpha-olefin having 4 to 8 carbon atoms and 1 to 50% by weight of one crystalline polypropylene.
- Fibers as they are obtained according to JP 02 139415 A2, do not meet all the requirements placed on the handle and the latent shrinkage.
- the process described therein consists of side-by-side with one component consisting essentially of polyethylene terephthalate and a second component consisting of a polyester composed of ethylene glycol, terephthalic acid and isophthalic acid and an aromatic dicarboxylic acid with sulfonate groups -Side threads spun.
- JP 2 145 811 A for the production of bicomponent fibers with latent crimpability also does not lead to fibers which are distinguished by a particularly soft hand and increased latent crimpability.
- EP 0496 734 B1 should also be mentioned, in which thermally bonded non-moist fiber products are described, comprising high-performance fibers such as polyesters, polyamides, silk, etc., which are thermally bonded with colorable thermoplastic two-component fibers.
- the core / shell arrangement with asymmetrical configuration is also mentioned.
- This object is achieved by a process for producing an eccentric bicomponent fiber of the core / sheath type with a soft feel and improved latent crimp, by melt spinning polyester as the core component and polyethylene as the sheath component at a spinning speed of 600 to 2000, preferably 600 to 1 400 m / min. an eccentric core / sheath fiber with a sheath proportion based on the cross section of the fiber from 35 to 70%, the fiber thus obtained at a temperature of 40 to 70 ° C stretched by the ratio W max + 20% and then crimped, under VV max is the draw ratio at which the number of sheets per cm (Bg / cm) reaches a maximum and W max is determined as indicated below. It is preferably stretched at a temperature of 50 to 60 ° C.
- the bicomponent fiber is produced as a core / sheath fiber with extreme eccentricity, the extreme or greatest eccentricity being achieved when the core component extends to the outer edge of the sheath components, as is shown schematically in Figure 1.
- Polyethylene terephthalate is particularly suitable as polyester.
- types of polyethylene can be used as the polyethylene for the jacket component.
- linear ethylene polymers such as linear high density polyethylene (HDPE), which has a density in the range from 0.941 to 0.965 g / cm 3 and linear low density polyethylene in (LLDPE), which typically has a density in the range of low density polyethylene (LOPE) ) and linear medium density polyethylene (LMDPE), i.e. densities in the range of about 0.1 to 0.94 g / cm 3 .
- HDPE linear high density polyethylene
- LLDPE linear low density polyethylene
- LLDPE linear medium density polyethylene
- Linear ethylene polymer densities can be measured according to ASTM D-792; a corresponding definition can be found in ASTM D-1248.
- These polymers can be made using coordination catalysts; they are generally known as linear polymers because they have essentially no branched chains as can arise when monomers are polymerized onto the main polymer chain.
- LLDPE is a linear low density ethylene polymer in which ethylene has been polymerized with minor amounts of ⁇ - ⁇ -ethylenically unsaturated alkenes having from 3 to 12 carbon atoms per alkene molecule, especially 4 to 5 carbon atoms. It is advantageous to produce the fiber with a titer of 2 to 7 dtex; this titer refers to the fiber after drawing; stretching with a ratio W _ mi is preferred. in the range of 1.4 to 2.4 ⁇ 20%.
- Another object of the invention is the use of the bicomponent fibers, produced by one of the methods described above for the production of hygienic products.
- the bicomponent fibers are preferably used for the production of hygienic textile fabrics, in particular nonwovens.
- a particularly advantageous form of use is the production of diapers, bandages or inserts and the like.
- the core component can consist of conventional melt-spinnable polyester material.
- polyester material consist predominantly of building blocks which are derived from aromatic dicarboxylic acids and from aliphatic diols.
- Common aromatic dicarboxylic acid building blocks are the divalent residues of benzenedicarboxylic acids, especially terephthalic acid and isophthalic acid;
- Common diols have 2 to 4 carbon atoms, with the ethylene glycol being particularly suitable.
- a polyester material which consists of at least 85 mol% of polyethylene terephthalate is particularly advantageous.
- the remaining 15 mol% then build up from dicarboxylic acid units and glycol units, which act as a so-called modifying agent and which allow the person skilled in the art to further influence the physical and chemical properties of the fibers produced in a targeted manner.
- dicarboxylic acid units are residues of isophthalic acid or of aliphatic dicarboxylic acid such as. B. glutaric acid, adipic acid, sebacic acid;
- modifying Diol residues are those of longer-chain diols, e.g. B. of propanediol or butanediol, of di- or triethylene glycol or, if present in small quantities, of polyglycol with a molecular weight of 500 to 2000 g / mol.
- polyesters which contain at least 95 mol%
- Such polyesters usually have a molecular weight corresponding to an intrinsic viscosity (IV) of 0.5 to 1.4 (dl / g), measured on solutions in
- the melting point of the polyester component and the melting point of the polyethylene component differ by at least 30 ° C, since the lower melting component, namely the polyethylene, can also serve as a binding material in the production of bonded nonwovens, other textile fabrics and other hygienic products . should.
- the core is not centered symmetrically in cross section, but eccentric. It is advantageous if the core is shifted as far as possible from the center to the periphery; the position with extreme eccentricity is particularly advantageous, that is to say that the core component extends to the edge of the shell component, in accordance with a configuration according to Figure 1, ie from the periphery of the cross section has at least one point in common tangentially.
- the spinning speed in the process according to the invention is between 600 and 2,000, preferably between 600 and 1,400, m / min.
- the exit speed at the nozzle exit surface is matched to the spinning speed and the draw ratio so that a fiber is produced with the desired titer, ie a titer of about 2 to 7 dtex.
- Spinning speed is to be understood as the speed at which the solidified threads are drawn off.
- the threads drawn off in this way can either be fed directly to the drawing or also wound up first and drawn at a later point in time by the ratio W max .
- the required ratio W max is determined in the following way.
- bicomponent threads of the core / sheath T type are spun with the eccentric position of the core, then about 10 samples are drawn individually with a different ratio, namely with drawing ratios between 1.2 and 2.6, whereby the
- the drawing takes place for all samples at the same temperature between 40 and 70 ° C, preferably at 55 ° C.
- the samples are then crimped in a stuffer box. After crimping in the stuffer box, the fibers are subjected to a thermal treatment at 120 ° C. and a dwell time of 3 minutes. The number of sheets per centimeter (Bg / cm) is then counted for the respective samples and the crimp K1 determined in accordance with DIN standard 53840. The values obtained are shown graphically as a function of the draw ratio.
- Figure 2 shows a corresponding determination of the value VV max for a fiber with a titer of 3.0 dtex and a core / sheath ratio of 50:50.
- the W max value is 1.7.
- the VV max value is the maximum curve number / cm (as ordinate) and
- Draw ratio (abscissa) and serves as a process parameter for the process according to the invention.
- Bicomponent fibers are manufactured which have a core / shell ratio of 50:
- Core / shell ratios can be determined by appropriate tests.
- the maximum of the crimp K1 may coincide with the maximum for the number of sheets, but need not.
- Figure 3 also shows the course of the crimp K in dependence on W.
- the method according to the invention can be carried out in production.
- the fibers stretched by the ratio VV raax are then crimped.
- the fibers crimped in this way can be cut into staple fibers and then processed into corresponding products, in particular textile products, preferably hygienic products, hygienic textile fabrics, hygienic nonwovens, diapers, bandages or inserts and the like, but also into cotton balls, etc.
- the process according to the invention provides the fibers with an additional latent crimp, which can be triggered in the further processing by thermal treatment at temperatures of about 100 ° C.
- the number of sheets already obtained due to the crimping in the stuffer box is increased.
- the fiber not only has a soft feel, but also helps to increase the bulk of the corresponding products.
- the fleece can be strengthened accordingly by appropriate thermal treatment at temperatures at which the jacket component softens or begins to melt.
- a bicomponent spinning system was used to produce spun fabric with an eccentric cross-section from standard polyester in the core and polyethylene in the jacket.
- the total throughput with a core / shell ratio of 50/50 was 380 g / min per spinning station with an 827 hole nozzle.
- the individual spider titer set was 4.60 dtex.
- the take-off speed was 1,000 m / min.
- the melt temperature of the polyester was 285 ° C, that of the polyethylene 265 ° C.
- the spun filaments were cooled with an inside / outside blowing over a blowing length of 500 mm and an air volume flow of 280 m 3 / h at an air temperature of 40 ° C. To simplify, the filaments were prepared with a conventional finishing agent.
- the spun fabric was then presented to a conventional sliver mill and processed further.
- the stretching in the specified range especially in the specific case for a final titer of 3.0 dtex, was carried out at a stretching ratio of 1.7 between rotating rollers.
- the temperature of the rolls at which the stretching was triggered was 50 ° C.
- the fiber cable was mechanically crimped in a stuffer box crimping machine and then at 60 ° C. in one Belt dryer dried.
- the fibers were cut with a conventional staple fiber cutting machine.
