Description

Method for high-speed false twist texturing
Invention field
The present invention relates to the method for high-speed false twist texturing of synthesizing filament yarn, and relate to the purposes of the specific finish that is used for this deformation method.
From early eighties, mainly use so-called POY (partially oriented yarn) the spinning process production of carrying out the false twisting draw texture subsequently as the polyester fine bulk yarn of dress material or the use of furniture outer cover material.
In the false twisting draw texture, with drawing-off simultaneously of PES-POY yarn and varicosityization.By yarn brute force under its mecystasis is twisted, backtwisting after cooling makes this yarn fluffy.By yarn is contacted the mecystasis that obtains this yarn with hot ring rail (rail).This twisting is mainly produced by pottery or polyurethane grinding disk (twisting unit).In recent years, the speed of false twisting draw texture (FT) steadily improved (explanation to its basic principle can be at H.K.Rouette, Lexikon der Textilveredlung, 1995, the 1524-1531 pages or leaves and 2180-2183 page or leaf find).To middle nineteen nineties, the speed of standard yarn is generally 700 meters/minute to 900 meters/minute.In order to obtain these speed, be necessary to use the heating ring rail (＞2.5 meters) of very long biphenyl heating.The cooling ring rail is also had to increase length and is arrived greater than 1.5 meters.These machines are quite big and be difficult to operation.The early 1990s, owing to novel heater occurred on the market, false twisting draw texture equipment is compact more.Thread passage length in these machines obviously shortens, and this has reduced tension buildup and the potentiality that improve speed have been arranged.Compare between traditional contact heater of 180-230 ℃ with temperature, the operation of new heater is not contact in fact, but its temperature is greater than 500 ℃.By means of very high temperature, new type heater length can be reduced to about 1 meter.Although the maximal rate of this hot machine generally can reach 1500 meters/minute, in fact find, its speed seldom surpass 900-1000 rice/minute.Its reason is that at a high speed the end breakage rate of yarn is also very high down.People know that before the yarn breakage rate increased, peak tension increased sharply usually.Therefore, for the PES-POY yarn, need especially and can obviously reduce the end breakage rate that is tending towards the peak tension tendency and comes from this again having on the Texturing Machines of new high temperature heater (HTH) with its processing.
Except improving yarn and spinning process, also consider in order to optimize the finish of lubricate that in spinning, must on yarn, use and main.For example, EP 826816 A2 have described employed finish in the synthetic yarn false twist texturing, this finish contain with cyclic polyorganosiloxane with the quantity selected than the polyether compound that mixes.Yet even use this finish, its speed only may reach 1000 meters/minute, and this is particularly because in the time of temperature 350-500 ℃, the polysiloxanes thermal oxidative degradation becomes hardening portland, is deposited on the thread guide of high temperature heater (HTH).

As in the table as a result as can be seen, the data of this method and yarn are in a kind of extraordinary level.Particularly, compare with conventional finish, the inferior numerical value that surpasses the tension limit of the end breakage rate that is determining yarn has obviously reduced.
In order to prove that adding water-insoluble liquid (B) in the distortion finish can obviously reduce what is claimed is effectively of yarn tension crest frequency, the following four kinds of finishes of test on an other PES-POY spinning machine: reference, 13,3 and 9.
The parameter 2 of spinning and POY yarn:
Spinning speed: 3300 meters/minute
Yarn type: 167 dtex, 30
Oil: crust Maag gear pump and the pottery device that oils
Emulsion concentration: 10%
Finish addition: 0.30%

The tension limit of fault alarm :+/-3 cN
Coiling speed: 900 meters/minute
D/Y ratio: 1.8
Draw ratio: 1.76
Heter temperature: 380 ℃-first districts
400 ℃-second districts
Set heter temperature: close switch
The result:
Finish Reference ????13 ????3 ????9
Through 4 hours, surpass the inferior numerical value of tension limit ????108 ????18 ????17 ????18
In this case, the beneficial effect of the inventive method also clearly, the peak tension frequency obviously reduces in deforming process.
Test with another water-insoluble low viscosity component (B).Select finish 9 to be basic recipe (quantity is percetage by weight):
????9 ????16 Viscosity (mPas) during 20 ℃ of components (B)
????(Ⅰ) ????38.0 ????38.0
????(Ⅲ) ????10.0 ????10.0
Stearic acid 2-ethylhexyl ????6.0 15 to 17
Sad octyl group ester ????6.0 4 to 7
Composition 1 ????46.0 ????46.0
All these four kinds of finishes are used for the POY spinning machine, and it has spinning and POY yarn parameter 2.Then on RPR2 SDS high temperature heater (HTH) machine with this Yarn texturing.
Deformation parameter 3:
Machine Type: RPR 3 SDS
Friction element: Temco FTS 521 M
Unit configuration: 1-6-1,9 millimeters polyurethane scratch diskettes of Temco 630F
The tension limit of fault alarm :+/-3 cN
Coiling speed: 1000 meters/minute
D/Y ratio: 1.76
Heter temperature: 500 ℃-first district
500 ℃ of-second districts
Set heter temperature: close switch
The result:
Finish ?9 ?16
Through 4 hours, surpass the inferior numerical value of tension limit 36 ?25
As can be seen, the reduction of the viscosity of component (B) also can reduce the number of times above tension limit, and therefore reduces the danger of yarn breakage.
