Definitions
- the invention relates to coating compositions for fibers and a method for their Manufacturing.
- the invention relates in particular to preparation agents for elastanes Basis of a dispersion of fatty acid metal salts and agglomeration inhibitors in Polyorganosiloxanes and mineral oils.
- the preparations are made through a precipitation process made from fine-grained and sedimentation-stable dispersions result in a narrow grain size distribution and are free of agglomerates.
- the Coating agents reduce the electrical resistance of elastanes, whereby neither in the application nor in the processing of the elastane, even with one deposits of coating agents on machine parts for a long period of time. Elastanes treated with the coating agents stick even after a long time Storage time not and remain processable.
- fiber used in the present invention includes fiber Staple fibers and / or continuous filaments.
- the fibers e.g. Elastane can by spinning processes known in principle, such as the dry spinning process, the wet spinning process or the melt spinning process.
- Elastane i.e. elastic polyurethane fibers made from long-chain synthetic polymers, which are at least 85% segmented polyurethanes based on e.g. Polyethers, polyesters and / or polycarbonates are well known. Yarns made from such fibers are used to manufacture fabrics or fabrics or fabrics that are used for the manufacture of corsetry, Linen, stockings, sportswear and ribbons are suitable. Polyurethane fibers have considerable compared to other, non-elastic textile fibers Stickiness. Bonding of the elastanes occurs particularly when elastanes be wound on a spool or a partial warp beam. A sticking of the Spandex or the increased adhesion of the fibers to one another is particularly then observed when the fibers are stored for a long time before further processing were. This effect is exacerbated if the storage of the material is elevated Temperature.
- the stickiness or the adhesion of elastanes to spools or partial warp beams can be used when processing the polyurethane fibers with, for example, polyamide fibers or cotton by a warp or circular knitting process or automatic hosiery lead to strong tension in the fiber during unwinding, which can lead to thread breakage can lead and in extreme cases bobbins or partial warp beams made of such fibers no longer processable.
- magnesium stearate with organic solvents such as Isopropanol, chloroform, Acetone or heptane made into a paste with polyorganosiloxane or mineral oil mixed and ground in a mill.
- organic solvents such as Isopropanol, chloroform, Acetone or heptane made into a paste with polyorganosiloxane or mineral oil mixed and ground in a mill.
- the disadvantage of this manufacturing process is that magnesium stearate is finely divided into the silicone oil by a complex grinding process is incorporated.
- organic solvents the time-consuming recovery of the solvents is necessary depending on the type of solvent, there is still a risk of ignition or explosion of the solvent.
- JP-188 875 is used to reduce the adhesion of polyurethane fibers described a preparation.
- This consists of a polydimethylsiloxane, a higher alcohol, its ether or a fatty acid ester consisting of a Fatty acid with at least 12 carbon atoms, a modified silicone and the, metal salt of a fatty acid with at least eight carbon atoms.
- the disadvantage however, the preparation mentioned is similar to that of the others described above known preparation.
- the dispersed metal soaps list during application Polyurethane fibers to build up deposits in the preparation system, for example can lead to the blockage of preparation lines. Associated with it the running time of the spinning machines is shortened. The cleaning effort for cleaning the spinning machines and the preparation system is increased considerably. A safe and even preparation of the polyurethane fiber over a long period of time is not achieved with such preparations.
- JP-60-67 442 describes the preparation of finely divided particles of fatty acid metal salts in polydimethylsiloxane for the preparation to reduce the adhesion of elastanes.
- Magnesium stearate or calcium oleate is dissolved in a pressure-stable vessel in hexane or benzene at 140 or 130 ° C and precipitated by rapid cooling at 10 0 C / min. Entering this dispersion in low-viscosity polydimethylsiloxane and then distilling off hexane or benzene finally leads to the ready-to-use preparation.
- the disadvantage of this preparation is the complex and costly preparation process for the preparation caused by the distillation of hexane or benzene.
- DD-251 578 is used to reduce the adhesion of elastanes be prepared by the wet spinning process, the use of an aqueous Suspension with finely divided magnesium and / or calcium stearate and optionally Polydimethylsiloxane described as a preparation.
- the disadvantage of this invention is however. that to remove the water from the dispersion after application the polyurethane fiber requires special drying of the fiber. So that's a additional processing step connected, which increases the cost of the product leads.
- the invention has for its object a preparation for fibers, in particular for elastanes, to be made available, for example, during application Roll, thread guide or spray technology is easy to process and those in the application and especially in the processing of elastanes with, for example Cotton or polyamide fibers for surface goods not for deposits in the preparation system or on processing machines.
- the stickiness Elastane is said to be reduced by the preparation and the processability of using the preparation coated elastane guaranteed even after a long storage period be.
- Further requirement for preparations for elastane, if they are solids contained, in the form of dispersions, is to ensure a uniform Preparation order and coupled with it an even application of solids by stabilizing the preparation against sedimentation.
- the stability of dispersions depends on many factors such as the particle size and shape, polarity, charge and density. However, among all these factors is the Particle size is the most important factor influencing sedimentation stability. Therefore it must be a primary goal in the production of suitable dispersions, set the grain size of the solid in the preparation as low as possible. the primary particles must not agglomerate into clusters.
- Another object of the invention is an improved Processes for making preparations for fibers are available too make grinding unnecessary.
- the preparation oils according to the invention for fibers in particular Polyurethane fibers. in the form of dispersions.

- the preparation shows good stabilization against sedimentation, but is due to the strong Tendency to agglomeration and the increased viscosity, probably due to strong interactions between the solid particles in the preparation, not as a preparation oil for the production of fibers, especially polyurethane fibers, suitable.
- Experiment 2-2 shows that polyamylsiloxane is part of the preparation Electrical volume resistance of polyurethane fibers reduced, this branched So siloxane increases electrical conductivity. This result corresponds the observation made in U.S. Patent 3,296,063.
- the volume resistance of phosphoric acid ester and / or Na dioctyl sulfosuccinate was increased however, the polyurethane fibers are further lowered, i.e. the electrical Conductivity increased further.
- Na dioctyl sulfosuccinate is in front of the phosphoric acid ester and this in turn is the most effective before polyamylsiloxane Means for reducing volume resistance.
- Experiments 3-1 and 3-2 show that when applying preparations based on silicone oil or silicone oil with polyamylsiloxane the increase in Adhesion of polyurethane fibers with a storage time of 8 weeks and a temperature of 40 ° C, as is often the case during transport, in warehouses or subtropical countries occurs, is very strong and the processability of the coils is often not possible is.
- the adhesion values obtained in these experiments are above 1 cN, which is a limit for successful processability of polyurethane fibers on a circular knitting machine, for example. Liability of more than 1 cN when processing the bobbins into thread breaks, with the consequence of Machine downtime. In extreme cases, even a thread of the Be pulled out.
- the preparations used in experiments 3-1 and 3-2 based on silicone oil or silicone oil with polyamylsiloxane are therefore not suitable for the preparation of polyurethane fibers.
- Mg stearate in the preparations for reducing the Tackiness of polyurethane fibers is, however, among those who go through a milling process were produced, less than those produced by precipitation in the Mixing nozzle or precipitation in the boiler with subsequent homogenization were. This is enough for preparations caused by the case processes described were produced, 1 wt .-% Mg stearate from the stickiness of polyurethane fibers to reduce to the desired level.
- the one produced by a precipitation process Preparation is to set the same behavior regarding liability behavior a Mg stearate content of 4% by weight is necessary.
