Test portion 3 (adhering to synthetic fiber on synthetic fiber processes and estimate with finishing agent, false twisting)
On synthetic fiber, adhere to the synthetic fiber finishing agent
The synthetic fiber of preparation in the test portion 2 are uniformly mixed into the 10% water-based liquid of synthetic fiber with finishing agent with finishing agent and dilution water.With intrinsic viscosity be 0.64, titanium oxide content is that 0.2% polyethylene terephthalate thin slice is by after the conventional method drying, use the extruder spinning down at 295 ℃, extrude from spinning head, behind cooling curing, on the strand that moves, use the conduit of band measuring pump to give oil process, adhere to above-mentioned 10% water-based liquid with reach synthetic fiber as table 4 record with the finishing agent adhesion rate after, use the conduit boundling, under the situation of not following mechanical stretching, reel with 3000m/ minute speed, obtain the partially drawn yarn of 56 dtexs, 144 monofilament of 10kg volume cheese formula.
False twisting processing
The above-mentioned spinning cake that obtains is supplied in the following false twisting processing.Use contact heating type false twisting machine (Supreme Being people makes the SDS1200 of machine corporate system), under 2 kinds of conditions of process velocity=800m/ minute and 1200m/ minute, in stretching ratio=1.652, execute sth. made by twisting mode=3 reel circumscribed friction modes (1 on the side's of entering godet, 1 on output side's godet, 4 on hard polyaminoester dish), twisting side heater=long 2.5m, 210 ℃ of surface temperatures, backtwisting side's heater=nothing, under the condition of target twisting count=3300T/m, carry out the false twisting processing of running continuously in 25 days.
The evaluation of fluffing
In above-mentioned false twisting processing, before false twist yarn is batched, measure hourly approximate number with fluffing counting device (DT-105 of eastern レ ェ Application ジ ニ ァ リ Application グ corporate system), estimate by following standard.The results are summarized in the table 4.
◎: an approximate number of mensuration is 0
◎-zero: an approximate number of mensuration is not less than 1 (but comprising 0)
Zero: the approximate number that rises of mensuration is 1-2
△: the approximate number that rises of mensuration is 3-9
*: mensuration rise an approximate number be 10 or more than
The evaluation of broken end
Will be in above-mentioned false twisting processing, the broken end number of times that produced in 25 days of turning round continuously is converted into the number of times of every day, estimates by following standard.The results are summarized in the table 4.
◎: the number of times that produces broken end is 0 time
◎-zero: the number of times that produces broken end is not less than 0.5 time (wherein, comprising 0)
Zero: the number of times 0.5-that produces broken end is less than 1 time
△: the number of times 1-that produces broken end is less than 5 times
*: the number of times that produces broken end be 5 times or more than
Chromatic evaluation
The false twist yarn of above-mentioned fluffing has been measured in use, and making diameter in cylindrical knitting machine is 70mm, and length is the knitted fabric of 1.2m.Use DISPERSE DYES (the trade name カ ャ ロ Application Port リ ェ ス テ Le Block Le of Japanese chemical drug corporate system-EBL-E), this knitted fabric is dyeed by high-pressure dyeing.With the knitted fabric of conventional method water washing dyeing, after reduction washing and the drying, being contained in diameter is 70mm, and length is in the work durm of 1m, and with the naked eye number goes out counting of knitted surfaces deep colour dyeing part, estimates.Carry out 5 same evaluations, the evaluation result that obtains is converted into counting of each knitted fabric, estimate according to following standard.The results are summarized in the table 4.
◎: no deep colour dyeing part
◎-zero: deep colour dyeing partly has 1 point
Zero: deep colour dyeing partly has 2 points
△: deep colour dyeing partly has the 3-6 point
*: deep colour dyeing partly have 7 or more than
