For example, when following ASTM D-35 12-82 for any tumbling type Knotted fiber pomp tester (1111 > 1) When classifying fiber pomp. This will be discussed later. Another thing that the present inventors have not fully understood is the hydrolysis of polymers in the form of fibers, especially during downstream processing, or its effect on NRV.

Description of the invention (6) (Please read the notes on the back before filling this page) If indicated The silicate chain-branching agent in the polymer can be hydrolyzed. When the polymer in the form of fibers is exposed to moisture, this tends to occur, for example, in the atmosphere, and especially at elevated temperatures During aqueous treatment, such as dyeing of fabrics and clothes. When the chain-branching agent bond is hydrolyzed, NRV tends to decrease more significantly than LRV. Therefore, it has the viscosity according to the present invention and its processability as described. It has very popular functional properties, such as polymers and spinned fibers, although it is within the narrative range when the polymer was originally spun (refer to polygon ABCDEFGA and preferably triangle JKLJ). The polymer provided during spinning is very popular The basis of functional fibers, fabrics and garments, but their NRV can be reduced below the range described (refer to polygon ABCDEFGA and preferably triangle JKLJ).

The fibers and polymers described in Example 1 of the present invention and, for comparison, were measured from fabrics made from a type 702W fiber having a fairly similar profile. In this regard, the improvements obtainable by the present invention are surprising. The grade of RTPT fiber pomp measured as described in the following is shown in Figure 3 as follows: 1.

The test procedure is as described in the aforementioned U.S. Patent No. 5,817,74. However, it has a part of the improvement of the test procedure of knotted fiber pomp. Because the existence of moisture required by the industry has been found to affect the results, the test conditions are stricter. It has proven to be better. The test described in the aforementioned US patent (in accordance with ASTM D-3512-82) uses dehumidified air at a pressure of 3 pounds per square inch (about 21 kPa). The ratings described herein are all performed at 25 pounds per square inch (about 17.5 kPa) of air, and the inventors have found that they are more stringent. Except for the rating using the dehumidified air measurement for the measurement in the aforementioned US patent, however, the other measurements were made by spraying water twice every 30 minutes (approximately 0.44 grams of water applied) The test is carried out in the presence of added moisture. Therefore, if it is to be understood that the RTPT rating is field comparable only when all fabrics are tested under the same conditions, the RTpT rating in this article should not be compared with the rating in the US patent, and The lamp rating in this article is provided for experiments with &lt; water and in the presence of added water, as described above.

In terms of this aspect, this functional experience is surprisingly good. These different polymer compositions are shown in Table V as Comparative Examples X, Y, and 2, and also mentioned in Table Craftsmanship. Table VI is provided in these Comparative Examples χ, γ &amp; ζ, and for type Properties of filamentous fiber used in 702W. Each of these comparative examples χ: Υ and 系 are spun essentially as described in Example τ into filamentous fibers and then processed into fabrics.

Comparative Example X The filamentary fiber used in Comparative Example X was produced from the &lt; copolyester spinning substantially as described for the example, but it had a relatively high amount of 0 · 322% (TES 0 / 〇) ' It's the picture in this article! The straight line Bc, 12 · 3. For comparison, these 値 of χ are marked as "Cx" on figure i, which are outside the polygon ABCDEFGA of figure i, and the estimated 値 are shown on figure 2, and are estimated from the pentagonal NMOPQM outer. The fibers obtained from Comparative Example X showed a considerable amount of "fly" waste (fibers and finished particles) during the processing stages of carding, roving, and spinning of synthetic yarns. Due to the reduced productivity and particularly inferior yarn quality (poor uniformity), such "flying '" waste is undesirable. However, the fabric has a fairly good function of knotting fiber balls.

For the "finished, the fiber in the fabric measured Xia 'NRV has been reduced to 100nrV, and (TES weight% ) The number is 0 · 09. The fiber used in Comparative Example Y was less popular because the elevation of Jiu, Fang, and Tuan during the melt-spinning period prevented the temple from being efficiently manufactured (although the fabric also has a fairly good quality). Knot fiber pompom function). In addition, the fiber has a very poor shape definition, as can be seen from the groove ratio in Table VI. However, as shown, when the filamentary fiber system is manufactured and processed into a fabric, the knot fiber pomp function is greatly improved beyond the Type 702W.

-Comparative Example Z The filamentary fiber used in Comparative Example Z was substantially manufactured as described in Example 丨 but has a relatively high viscosity, with 13 2NRV, and a relatively low amount of 0157% by weight (TES% ) (Use, relative to the weight f of dmt, about 0.22% by weight of tetraethyl orthosilicate, and about 66 million points of tetraisopropyl phthalate (TPT) 'and about 2.0: 1 Co-polyester spinning of EG · DMT measured in the reactor).
