Definitions
- the present invention relates to a method for applying a finish to a sewing thread with the features of the preamble of claim 1.
- Finishing agents which are generally also referred to as preparations, ensure that a sewing thread is not damaged as a result of thermal and / or mechanical stresses during its manufacture and / or later use.
- a finishing agent is applied to the surface of the sewing thread, which is more or less evenly distributed on the surface of the sewing thread.
- finishing agents have a different chemical structure.
- these are paraffins, solid or liquid fats or waxes.
- a finishing agent can also contain, for example, polymeric compounds based on alkylenes, polymeric compounds based on acrylates and / or polymeric organosilicon compounds, in particular silicones.
- additives generally also have antistatic agents, bactericides and / or emulsifiers.
- the sewing thread to be processed in each case is continuously guided over the surface of a solid finish block, a certain amount of the finish being removed from the finish block and brought to the surface of the sewing thread by the contact of the sewing thread with the finish block.
- an aqueous dispersion or emulsion of the finishing agent is sprayed onto the continuously transported sewing thread via suitable nozzle systems.
- the finishing agent to the sewing thread via an indirect application.
- the continuously transported sewing thread is brought into contact with the surface of a platen roller, which in turn partially protrudes into the corresponding dispersion or emulsion.
- the finishing agent to the sewing thread by means of an aqueous emulsion or aqueous dispersion lead, and then squeeze the entrained finishing from the sewing thread, spin off or strip off.
- the sewing thread to be prepared is first opened as a pile, in particular as a winding body.
- the pile or the winding body is then arranged in a conventionally designed dyeing apparatus and the pile or the winding body is flowed through or through with an aqueous dispersion or an aqueous emulsion of the finishing agent for a predetermined time. After this time has elapsed, the emulsion or dispersion of the finishing agent is broken by a change in the temperature or the pH value, which leads to the finishing agent being deposited on the surface of the sewing thread.
- the present invention has for its object to provide a method of the type specified with which finishing agents can be applied particularly uniformly to the surface of a sewing thread.
- a pile in particular a winding body, is first produced from the sewing thread.
- a fluid containing the finishing agent is then flowed through and / or flowed through the pile or the winding body, a supercritical fluid being used as the fluid.
- the temperature is reduced, the pressure is reduced and / or the volume is increased, which leads to the finishing agent being knocked onto the surface and / or partly inside (interstices between threads) of the sewing thread.
- the term supercritical fluid is understood to mean such a fluid in which the pressure and / or the temperature of the fluid is above the critical pressure characteristic of the respective fluid, the critical temperature and / or characteristic of the respective fluid the volume is above the critical volume.
- a supercritical fluid which is also usually referred to as a "supercritical" fluid, is thus above the critical point, which is a certain size for the fluid used in each case.
- the conventionally designed additives which are insoluble in water and are very difficult and unstable to emulsify or disperse, completely or almost completely dissolve in a supercritical fluid, or are stably dispersible or emulsifiable, so that the The method according to the invention flows through or flows through the pile produced from the sewing thread or the winding body with a stable system consisting of a solution, dispersion or emulsion of the finishing agent in the supercritical fluid.
- the method according to the invention enables reproducible application of evenly distributed finishing layers.
- the method according to the invention has further advantages. Since the process according to the invention uses a solution or a stable emulsion or dispersion of the finish in the supercritical fluid, this means that the pile or the winding body of the sewing thread is always uniform over its entire extent with that of the finish Fluid is wetted so that there is also a uniform amount of finish at every location of the sewing thread as seen over the length and the circumference of the sewing thread.
- sewing threads which have been unevenly finished are thus excluded in the method according to the invention, which makes it clear that the sewing thread treated according to the invention shows a significantly lower frequency of thread breakage in processing and use compared to a sewing thread advanced according to a standard method.
- the sewing thread processed according to the invention there is no abrasion of finishing agents on deflection members, which is often the case with sewing threads which have been finished using the known methods.
- the method according to the invention is particularly environmentally friendly since there is no waste water contaminated with residual acid.
- lowering the temperature, lowering the pressure and / or increasing the volume means that the supercritical fluid is converted into the corresponding gas or into the corresponding liquid, in which case the finishing agent is obtained as a pure product which is simply derived from the gas or can be separated from the liquid, for example by filtration or absorption.
- the resulting gas or the resulting liquid of the fluid can then be
- REPLACEMENT LEAF can be collected and reused without loss.
- the drying of the finished material can also be omitted, since it is only necessary to change the temperature, the pressure and / or the volume of the supercritical fluid used to such an extent that the supercritical - see fluid being converted into its gas state.
- a further, very significant advantage of the method according to the invention is that the supercritical fluid containing the finishing agent can flow through the winding body or the pile significantly faster and with considerably lower differential pressures due to the gaseous viscosity in the supercritical state, while the known method, in which work is carried out in aqueous systems, requires considerably higher differential pressures with poorer and more uneven flow conditions with comparable winding body densities or pile densities.
- the finishing agents can be applied to the sewing thread in a particularly uniform manner.
- the reason given in the improved flow conditions reproduced above is why the process according to the invention can be operated with considerably shorter liquor ratios compared to the conventional process, so that the process according to the invention can be carried out particularly economically.
- a first embodiment of the method according to the invention provides that the lubricant is first dissolved in the supercritical fluid, then the solution is allowed to flow through the pile or the winding body for a predetermined time and then the pressure of the fluid is reduced. This ensures that the finish is fixed on the surface of the sewing thread, while the fluid is converted into the corresponding gas by the pressure drop, which is best brought about by a corresponding increase in volume, so that the thread is not fixed on the sewing thread Avivage is obtained as a corresponding pure product and can be easily separated from the then gaseous fluid in the manner described above.
- the time required for the pressure drop of the fluid in this process variant depends crucially on the mass of the sewing thread to be activated and thus on the size of the machine in question.
- the time required to lower the pressure accordingly varies between approximately 0.2 s and approximately 4 s.
- the aforementioned time varies between approximately 4 s and approximately 10 s, while in the case of machines with a filling volume between approximately 1,000 l and approximately 2,000 l it lies between approximately 10 s and approximately 30 s.
- the pressure reduction described above can be carried out in stages or, preferably, suddenly. Especially at
- this time is between 30 seconds and 20 minutes, preferably between 2 minutes and 10 minutes , varies.
- the temperature which is selected for the finishing in the method according to the invention depends on the dispersibility, emulsifiability and / or the dissolving behavior of the finishing in the supercritical fluid selected in each case and the pressure of the supercritical fluid.
- the process according to the invention is carried out at a temperature between 10 ° C. and 290 ° C., preferably between 28 ° C. and 180 ° C. Accordingly, the pressure selected in the process according to the invention varies between 20 bar and approximately 280 bar.
- REPLACEMENT LEAF set avivage in the supercritical fluid.
- a fluid is preferably used that is supercritical at relatively low pressures and low temperatures.
- For this purpose come in particular carbon dioxide, which is supercritical at a temperature above 31 ° C. and a pressure above 73 bar, ethane, which is supercritical at a temperature above 32 ° C. and a pressure above 48 bar, n-ropane , which is supercritical at a temperature above 96 ° C and a pressure above 42 bar, n-butane, which is supercritical at a temperature above 152 ° C and a pressure above 37.5 bar, n-pentane, the is supercritical at a temperature above 196 ° C.
- the aforementioned fluids self-confidence Obviously can be used individually or in a mixture. It was found that the aforementioned fluids or mixtures of the aforementioned fluids have excellent dispersing, emulsifying and, in particular, also dissolving properties for a large number of conventional additives.
- Avivagen to change.
- these are polar substances, such as, for example, aqueous acids, aqueous alkalis or water.
- moderators of this type are particularly suitable which are non-toxic and which evaporate when the pressure or volume increases and / or the temperature is reduced, together with the fluid or fluid mixture which is then no longer supercritical.
- Low alcohols for example methanol, ethanol and / or propanol, are preferred for this purpose.
- moderators which swell the surface of the sewing thread in order to ensure that the finish applied is chemically and / or physically fixed to the surface of the sewing thread.
- These moderators are those who are usually used in the dyeing of such sewing threads and which swell the thread substrate.
- the concentration of the moderator added to the fluid depends on the one hand on the respective leveling agent and on the other hand on the correspondingly used fluid.
- the concentration usually varies between approximately 1% by weight and approximately 15% by weight, preferably between approximately 5% and 10% by weight, in each case based on the amount of fluid.
- finishing agent which is either based on oils, fats, waxes or polyalkylenes and / or organosilicon compounds, in particular
- Such a finish can consist of a single substance finish or preferably contain some or all of the above-mentioned components, in which case a finish mixture used in the process according to the invention is then preferably about 15% by weight to 25% by weight of fats, waxes and / or oils, 5% by weight to 20% by weight of polyalkylene, in particular polyethylene, and 30% by weight to 45% by weight of silicone oil and the usual accompanying substances, for example Contains bactericides, antistatic agents, thread locking agents and / or water.
- Such a finish mixture is preferably used with the above-mentioned supercritical fluids, in particular in combination with ethane, propane, butane, pentane and / or carbon dioxide, and is excellently soluble, dispersible or emulsifiable therein.
- a further, particularly suitable embodiment of the method according to the invention provides that the finishing agent and / or a component of the finishing agent is applied in layers to the sewing thread. It is thus possible, for example, to apply a layer of polyalkylene finish, in particular a layer of polyethylene finish, to the surface of the aforementioned finish, then apply a layer of oil, fat and / or wax finish and then to cover this second layer with a silicone oil layer (3rd layer), so that such a layering finish applied has a particularly good adhesion to sewing thread surfaces, which results in correspondingly good processing and
- REPLACEMENT LEAF useful properties ie, for example, low abrasion quantities and low thread break counts.
- a further embodiment of the method according to the invention provides that the finish forming the first layer or the finish constituent forming the first layer is carried out in a first step at a predetermined pressure and / or dissolves in a first fluid at a predetermined temperature and the fluid flows over the heap or the winding body in the supercritical state and preferably flows through it. Thereafter, the pressure and / or the temperature of the first fluid is changed, preferably reduced, and the result is that the dissolving behavior of this finish or of the finish constituent which forms the first layer is correspondingly worsened, so that thus the first layer of the finishing agent or the finishing agent component is produced on the surface of the sewing thread. Thereafter, in a second step, the further finishing agent and / or the further finishing agent component is dissolved in the first fluid and / or another
- the previously described method variant is preferably carried out until between two and six layers of the finishing agent or the finishing agent components have been applied to the sewing thread.
- a particularly suitable embodiment of the method according to the invention provides that before the finishing agent is applied, a thread-closing agent is taken up in a fluid (emulsified, dispersed, dissolved) and the corresponding solution, dispersion or emulsion flows through the aggregate in the supercritical state or inflows. This ensures that the thread closing means, which is preferably used in the particular
- Fluid is soluble in the capillary spaces of the sewing thread, which is particularly the case when the sewing thread has a relatively open structure, as is the case with sewing threads which have been produced by a intermingling process.
- the temperature and / or pressure is reduced and / or the volume is increased, as a result of which the supercritical fluid is converted into the corresponding gas or liquid, which the thread-closing agent is unable to dissolve.
- the finishing agent is then applied in the manner described above.
- a method of this type has the advantage that a sewing thread that has been finished in this way, in addition to excellent thread closure, has excellent processing and use properties, which can be found in one correspondingly low thread break frequency and particularly high sewing performance.
- any thread closure means can be used for the procedure described above, which ensures that the capillaries stick together.
- a thread-closing agent is used which is based on an organic polymeric compound, in particular on the basis of a polyalkylene, a polyacrylate and / or a polyvinyl alcohol.
- the amount of thread closure agent applied depends on the structure of the sewing thread to be prepared. It usually varies between 5% and 10% by weight, based on the mass of the sewing thread to be treated.
- the amount of finishing agent applied in the method according to the invention depends on the construction of the respective sewing thread as well as its stress during processing and use. It is preferably between 0.5% by weight and 15% by weight, based on the mass of sewing thread.
- the process according to the invention is carried out in a liquor ratio of 1: 1 to 1:20 (thread count: fluid mass), in particular in a liquor ratio of 1: 2 to 1: 5.
- the method according to the invention can basically be applied to each sewing thread. However, it is particularly advantageous if a synthetic sewing thread, such as one in particular
- the method according to the invention can, however, be used excellently whenever a polyester sewing thread or a polyester-containing sewing thread is used as the sewing thread.
- the sewing threads mentioned above are core threads, multifilament threads or filament / fiber threads, which can possibly be twisted.
- the aforementioned sewing threads can have the construction of a swirled thread or a wound game.
- the titer of the aforementioned sewing threads varies in the order of magnitude between 50 dtex x 2 (total titer 100 dtex) and 1,200 dtex x 3 (total titer 3,600 dtex).
- a Nm 25/2 polyester sewing thread was opened as a bobbin (1 kg) and treated in a conventionally designed dyeing machine at a liquor ratio of 1:25 with the finishing emulsion or dispersion shown below:
- composition of the finish emulsion / dispersion Composition of the finish emulsion / dispersion:
- silicone oil 40% by weight silicone oil (viscosity 35,000 cSt)
- the Aviva fleet was heated from 20 ° C to 60 ° C at a heating rate of 2 ° C / min.
- the Aviva liquor then flowed through the winding body for 15 minutes. Thereafter, the Aviva fleet of 60 ° C was at a cooling rate of 3 ° C / min
- the coil thus treated was dried at 100 ° C.
- the flow during application of the finishing agent was from the inside to the outside, so that the above-mentioned increased edition height (7.6% by weight) of the inner layer was explainable.
- Example 1 The sewing thread mentioned in Example 1 was finished in the same form (winding body) on a high-pressure laboratory system,
- the finish had the following composition:
- the liquor ratio was 1: 3.
- Example 2 The sewing behavior of the material treated according to Example 2 was determined as in Example 1. The following values were shown in Table 4.
