Test Classification 2 (evaluation of aqueous liquid)
Production of drawn yarn
A predetermined amount of ion-exchanged water was further added to the aqueous solutions of the respective examples obtained as described above, and the mixture was uniformly mixed to prepare an emulsion having a concentration of the treating agent of 10%. Pellets of polyethylene terephthalate having an inherent viscosity of 0.64 and a titanium oxide content of 0.2% were dried by a conventional method, and then spun at 295 ℃ using an extruder. After discharged from the nozzle and cooled to harden, the emulsion was attached to the moving yarn by an oil-feeding method using a metering pump so that the treating agent was 1.0% with respect to the moving yarn. Then, the filaments were bundled by a guide and drawn at a speed of 1400 m/min by a drawing roll heated to 90 ℃ and then drawn between the drawing roll and a drawing roll rotating at a speed of 4800 m/min by a factor of 3.2 to produce 83.3dtex (75 denier) 36filament drawn yarns. Using the produced drawn yarn, the quality stability was evaluated by the following method. In addition, the low temperature stability of the aqueous liquid was evaluated by the following method. The results are shown in Table 1.
Evaluation of quality stability
The drawn yarn obtained by the above method was stored at 25 ℃ C.. times.65% RH for 3 months. After storage, the coefficient of friction of the yarn was measured, and the change before and after storage was confirmed. The quality stability was evaluated by the following evaluation criteria. The results are shown in Table 1 under the heading "quality stability". The friction coefficient was determined by the following method.
Using a friction tester (manufactured by EIKO SOKKI Co., Ltd., SAMPLEFRICTIONUNIT MODEL TB-1), a chromium-plated roughness having a surface roughness of 2S was placed between two movable rolls with a diameter of 1cm, and the drawn wire from the package (500g roll) was brought into contact with the chromium-plated roughness at an angle of 90 degrees. An initial tension (T1) of 5g was applied to the inlet side under a condition of 60% RH at 25 ℃ and 2 times of tension (T2) on the outlet side when the film was moved at a speed of 100 m/min was measured every 0.1 second for 1 minute. The friction coefficient was obtained from the following equation.
[ number 1]
Coefficient of friction ═ 2/3.14 x ln (T)2/T1)
Very excellent (excellent): the change of the friction coefficient is less than 1%
Excellent (good): the friction coefficient is increased by more than 1 percent and less than 5 percent
O (acceptable): the friction coefficient is increased by more than 5 percent and less than 10 percent
X (bad): the friction coefficient is increased by more than 10 percent
Evaluation of Low temperature stability
The low temperature stability of the aqueous liquid was evaluated in terms of liquid uniformity retention and coagulability. The liquid uniformity retention property and the solidification property were determined by the following methods.
60mL of the aqueous solution of the treating agent heated to 30 ℃ and stirred uniformly was placed in a plastic container having a lid and a capacity of 100mL (inner diameter: 45mm), and the container was sealed. And (3) standing the plastic container filled with the aqueous solution in a thermostat with the set temperature of 0 ℃ for 7 days. After standing, the appearance of the aqueous liquid was visually evaluated, and the liquid uniformity retention property and the coagulability were evaluated by the following criteria. The term "fluidity" used in the following reference means that when a plastic container containing an aqueous liquid is placed on its side (90 °), a part of the aqueous liquid flows out of the container within 30 seconds, and is judged to have fluidity. The results are shown in the columns of "liquid uniformity retention" and "coagulability" in table 1.
Evaluation of liquid Uniform Retention
Very excellent (excellent): maintaining the liquid state, and making the liquid uniform
Excellent (good): the liquid state is maintained, and the liquid state is non-uniform although no delamination occurs
O (acceptable): maintaining the liquid state, but separating the liquid into two or more layers
X (bad): the liquid state cannot be maintained, and coagulation occurs
Evaluation of solidification Property
Very excellent (excellent): the appearance was hazy, no turbidity and fluidity
Excellent (good): the appearance was hazy and turbid, and the coating was partially hardened
O (acceptable): hazy appearance, cloudiness, and mostly hardening
X (bad): completely solidified without fluidity
As is clear from the results in table 1, the aqueous liquids of the examples were evaluated for their low-temperature stability and quality stability as well as for their superior stability. According to the present invention, an aqueous liquid which is excellent in low-temperature stability and can impart stability to the quality of fibers can be obtained.
