The tensile speed was controlled so that the number of seconds of fiber breakage was 20 seconds ± 3 seconds, and the test was performed at a relative humidity of 65% and a temperature of 23 ° C. The measurement results are shown in Table 1 below.

Assessment 3: LOI value measurement

For the fibers prepared in Examples 1 to 18 and Comparative Examples 1 to 4, the LOI values were measured in accordance with the ASTM D 2863 standard test method, and the respective measurement results are shown in Table 1 below.

Assessment 4: Melt Drop and Carbonization Assessment

Next, the dyeability evaluation was carried out in accordance with AATCC 61-2013 2A, and the results of each evaluation are shown in Table 2 below.

As can be seen from Table 1 above, the fiber masterbatch used to form the fiber in Comparative Example 3 contained only 100% by weight of ULTEM 1010 PEI, and since the glass transition temperature of the polyether sulfimine was relatively high, the processing temperature was also quite high ( 390 ° C). In contrast, Examples 1 to 18 are fibers made of fiber masterbatch according to the present invention, wherein the fiber masterbatch has both a polyether quinone powder and a polyester powder to process the spinning process. The temperature was lowered to about 250 ° C to 300 ° C. Therefore, compared with Comparative Example 3, the fiber was produced by the fiber masterbatch proposed by the present invention, and the processing temperature was remarkably lowered.

In addition, as can be seen from Table 1, Comparative Example 2, Comparative Example 3, and Comparative Example 4 The spinning speeds were 1000 m/min, 2000 m/min and 1000 m/min, respectively. In contrast, the spinning speeds of Example 3, Example 7, Example 8, Example 12, Example 13 and Example 18 in which the fiber masterbatch was made according to the present invention were 2500 m/min, 2500 m/min, 2500 m, respectively. /min, 2560 m/min, 2200 m/min, and 2500 m/min.

In terms of the flame retardant effect, the fiber masterbatch used to make the fiber in Comparative Example 1 contained only 100% by weight of the polyester powder modified by the flame retardant, as shown in Table 1, even if the LOI value was 28, However, it causes a melting phenomenon and does not cause carbonization. Further, the polyester powder in the fiber masterbatch of Comparative Example 2 was subjected to a modification treatment without a flame retardant, and the content of the polyether quinone powder (30% by weight) and the polyester powder in the fiber masterbatch of Comparative Example 4 The content of the body (70% by weight) does not fall within the range of the content proposed by the present invention (the content of the polyether sulfimide powder is, for example, 35 wt% to 55 wt%, based on the total weight of the fiber masterbatch, of the polyester powder The content is, for example, 45 wt% to 65 wt%, and as shown in Table 1, the LOI values of the fibers of Comparative Example 2 and Comparative Example 4 (all 21) are significantly lower than the LOI values of the fibers of Examples 1 to 18. And cause the phenomenon of melting.

In comparison, as can be seen from Table 1, Examples 1 to 18 are fibers made of fiber masterbatch according to the present invention, and the fibers produced have an LOI value of 25 to 32 and have good flame retardancy. The effect is not caused by the phenomenon of melting, and carbonization occurs. Further, the fibers prepared in Examples 1 to 18 were subjected to dyeing treatment, and as shown in Table 2, the fibers produced in Examples 1 to 18 were all dyeable. Therefore, the fibers made of the fiber masterbatch according to the present invention not only have good properties. The flame retardant effect can avoid the occurrence of dripping and has dyeability.

In summary, the method for producing the fiber masterbatch of the present invention performs powder refining treatment, powder dispersion treatment and kneading process on the polyether phthalimide powder, the polyester powder and the flame retardant, and A compatibilizing agent may be added in the case of mixing the polyether quinone powder, the polyester powder and the flame retardant to increase the compatibility and plasticity of the polyether quinone powder and the polyester powder. In this way, the formed fiber masterbatch has both a polyether quinone powder and a polyester powder, and thus can combine the material properties of the polyether quinone and the polyester. Therefore, the fiber made by using the fiber masterbatch has a good flame retarding effect and dyeability, and does not cause a melt drop phenomenon. At the same time, the present invention can significantly reduce the processing temperature and increase the spinning speed, thereby reducing the manufacturing cost, compared to the processing temperature of the polyether quinone fiber in the prior art of more than 350 ° C.
