Definitions
- the invention relates to a spinning process, in particular a dry spinning process, for the production of elastane fibers, in which the elastane spinning solution prior to spinning contains 0.8 to 2% by weight of polydimethylsiloxane with a viscosity of 50 to 300 mm 2 / s and 0.2 to 0, 6% by weight of ethoxylated polydimethylsiloxane with a viscosity of 20 to 150 mm 2 / s can be added.
- Elastane fibers are understood to mean fibers which consist of at least 85% by weight segmented polyurethanes exist.
- the elastic and mechanical Properties of such fibers are achieved in that for the production of Elastane fibers, for example polyurea polyurethanes from aromatic diisocyanates be used.
- Such elastanes are usually made by Spinning solutions after wet spinning or preferably after Dry spinning process manufactured. Both are suitable as solvents Process polar solvents, e.g. Dimethyl sulfoxide, N-methylpyrrolidone, Dimethylformamide and preferably dimethylacetamide.
- the object of this invention is to provide improved elastane fibers, after processing on warp knitting machines in dyed and finished textiles Produce a significantly lower streakiness without the processability in the to interfere with the intermediate steps required to manufacture the goods.
- this goal can be achieved by adding a mixture of polydimethylsiloxane (PDMS) with a viscosity of 50 to 300 mm 2 / s and ethoxylated polydidimethylsiloxane to this solution before spinning the polyurethane urea solution and then adding the Spinning.
- PDMS polydimethylsiloxane
- Eo ethylene oxide and Z is either hydrogen or a C 1 -C 6 -alkyl radical, x, y and m are integers greater than or equal to 1, which are preferably chosen so that formula (I) has the molecular weight of 4,000 does not exceed.
- Products of this type are manufactured, for example, by Union Carbide under the trade name Silwet®.
- Particularly suitable for the use according to the invention are those types which have a viscosity of 20 and 150 mm 2 / s and a molecular weight of approximately 600 to 4000. Unless expressly stated otherwise, all molecular weight data relate to the number average (M n ).
- PDMS polydimethylsiloxane
- DE-A-3 912 510 in which the production of Elastanes using a special spinning process, namely a dry spinning process for the production of coarse titer elastane fibers with the introduction of superheated Water vapor is described.
- Silicone oils are possible there among others Additives called flow improvers.
- U.S. Patent 4,973,647 mentions also spinning silicone oil. In no document is anything about the Effects of the oil stated after further processing. A special one Spinning combination of oils of certain properties will not work there mentioned.
- the polyurea polyurethanes are produced according to known methods Procedures.
- the synthetic structure of the Fiber raw materials according to the prepolymer process being in the first process stage a long chain diol in the solvent or melt with a diisocyanate is converted to a prepolymer so that the reaction product isocyanate end groups contains.
- Polyester diols and polyether diols are preferred as diols. Mixtures of polyester and polyether diols are also suitable.
- the Diols generally have a molecular weight of 1000 to 6000.
- polyester diols e.g. Dicarboxylic acid polyester suitable, both several contain different alcohols as well as several different carboxylic acids can.
- suitable polyesters preferably a molecular weight of 1000 to 4000.
- Suitable polyether diols are e.g. Polytetramethylene oxide diols, preferably with molecular weights from 1000 to 2000.
- Polyester or / and polyether diols can also be used in combination with diols which contain tertiary amino groups.
- N-alkyl-N, N-bis-hydroxyalkylamines are particularly suitable.
- the customary aromatic diisocyanates are optionally used in a mixture with small amounts of aliphatic diisocyanates. Particularly useful results are obtained with the following diisocyanates: 2,4-tolylene diisocyanate and corresponding isomer mixtures, also 4,4'-diphenylmethane diisocyanate or corresponding isomer mixtures. It is of course possible to use mixtures of aromatic diisocyanates.
- Another embodiment of the synthesis of elastane raw materials according to the invention consists of blending polyester and polyether-polyurethane prepolymers and then convert to polyurea polyurethanes in a known manner. That for the respective technical purpose favorable mixture ratio of polyester and Polyether diols can be easily determined by preliminary tests.
- the desired urea groups are introduced into the macromolecules through a chain extension reaction.
- the macro-diisocyanates synthesized in the prepolymer stage are usually reacted in solution with diamines.
- Suitable diamines are, for example, ethylenediamine, tetramethylene diamine, 1,3-cyclohexanediamine, isophoronediamine and mixtures of these diamines.
- the desired molecular weight can be set by using a small amount of monoamines, for example diethylamine or dibutylamine, during the chain extension.
- the chain extension itself can be carried out using CO 2 as a retardant.
- a mixture of polyester and polyether-polyurethane-ureas can also be used Completion of the elastane synthesis can still be carried out.
- the reactions described are usually in an inert polar Solvents such as dimethylacetamide, dimethylformamide or the like.
- the silicone oils are made in concentrations according to the method of the invention from 0.8 to 2% by weight, relating to the polydimethylsiloxane or 0.2 to 0.6% by weight, regarding the ethoxylated polydimethylsiloxane.
- the weight ratio from PDMS to ethoxylated PDMS in the finished phase is preferably from 1: 1 to 5: 1.
- the concentration data mean the content of oil in the finished spun elastane filament.
- the oils are introduced using a Master batch in which the oils together with other spinning aids, e.g. an anti-adhesive in the solvent, e.g. Dimethylacetamide can be dispersed.
- this master batch is made using a static or other mixer Spinning solution added.
- concentration of both silicone oils together in the Master batches are preferably from 15 to 22% by weight.
- Fibers produced by the process according to the invention have preferably a single titer of 10 to 160 dtex. Are particularly preferred multifilament fibers, consisting of 3 to 5 coalesced single capillaries. You own preferably a titer of approximately 33 to 55 dtex.
- the fibers After leaving the spinning shaft, the fibers can still be used with a conventional External preparation, which the processing in the following Ensures warping and knitting processes.
- the elastane fibers obtainable by the process according to the invention are further Subject of the invention.
- 1340 threads of diter 45 are used on a elastane warping machine (Type DSE 50/30 from Karl Mayer, Oberhausen) with a pre-stretching of 156% and a final stretch of 40% on two part warp beams (TKBs) tightened.
- a elastane warping machine Type DSE 50/30 from Karl Mayer, Oberhausen
- TKBs two part warp beams
- these partial warp beams are used together with two TKBs Polyamide dtex 44/10 from SNIA made an elastic warp knit fabric.
- Warp knitting machine becomes a warp chair type HKS 2 / E 32 (Karl Mayer, Oberhausen) used.
- the thread entry values for the elastane are 59.0 cm and for the polyamide 160.0 cm.
- the warp knitted fabric thus produced is then placed on a steaming table Vibration device relaxes, with differences in the raw material contained in the mesh density and the width of the goods are largely balanced.
- hot air fixation takes place on a stenter frame not prewashed for 40 seconds at 195 ° C and a lead of 8th %.
- the fixing width is 100 cm.
- the fixed goods are cold to perforated in a separate tenter frame passage Color trees wrapped.
- the optical uniformity is assessed by an optical control of the finished colored goods both in transmitted light and in reflected light and will assessed on a scale from 1 to 9.
- This The grading scale is valid for all elastane finenesses. Grades from 1 to 3 can be only achieve with coarser titers (> dtex 80). For the dtex 45 described here the grade 4 is a very even commodity, grade 5 only corresponds to a good one Uniformity, grade 6 of a satisfactory, but still top quality corresponding uniformity.
- the knitwear was made from an elastane polymer, which is made of a polyester diol of molecular weight 2000, which from Adipic acid, hexanediol and neopentyl glycol, with methylene bis (4-phenyl diisocyanate) ("MDI”) and then capped with a mixture of ethylenediamine (EDA) and diethylamine (DEA) chain extended.
