1 is a perspective view of a masterbatch of a wear resistant fiber according to an embodiment of the invention.

Referring to Figure 1, the masterbatch 10 of the abrasion resistant fiber of the present invention comprises from about 83.5 to 98.4 parts by weight of the nylon body 100, from about 1.5 to 15 parts by weight of the solid wear modifier 102 and from about 0.1 to 2 parts by weight.

It is particularly noted that the present invention utilizes a solid state modifier rather than a conventional liquid modifier, thereby avoiding the problem of uneven dyeability in subsequent processing steps. More specifically, among the conventional master batches, the low molecular weight liquid modifier is migrated to the surface of the master batch to lower the dyeing uniformity of the master batch. However, the modifier of the present invention is a high solid modifier which is uniformly dispersed in the masterbatch by the coupling agent, so that the problem of poor dyeing uniformity due to the movement of the liquid modifier does not occur. .

Further, the content of the solid modifier of the present invention is in the range of about 1.5 to 15 parts by weight based on 100 parts by weight of the master batch, so that cost and wear resistance can be achieved. Specifically, if the content of the solid modifier is too high, the cost is increased and the dyeability is lowered. If the content of the solid modifier is too low, the abrasion resistance of the resulting abrasion resistant fiber is insufficient. The content of the solid modifier of the present invention may be, for example, about 1.5 , 2, 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 or 100 parts by weight of the masterbatch. 15 parts by weight, or any of the above two values.

The above extruder can be a single-axis extruder or a two-axis extruder.

In one embodiment, the above kneading temperature is in the range of 200 ° C to 285 ° C (eg, 220 ° C to 265 ° C). In one embodiment, the kneading temperature is a stepwise temperature increase from a temperature change from the feed end to the discharge end. For example, the processing temperature can be divided into nine heating sections, which are about 220 ° C (feed end temperature), 235 ° C, 240 ° C, 250 ° C, 250 ° C, 255 ° C, 260 ° C, 260 ° C, and 265 ° C (discharge) Terminal temperature). However, the invention is not limited thereto. In another embodiment, the temperature change of the kneading temperature from the feed end to the discharge end may also be a stage temperature rise, a continuous temperature rise, or any suitable temperature control change.

The two-component core-sheath type composite fiber 300 includes a core 302 and a sheath 304. The sheath 304 is used to cover the core 302. The material of the core 302 may include Nylon 6, Nylon 6, 6, Nylon 6, 10, Nylon 6, 12, Nylon 10, 10, Nylon 11, Nylon 12 or a combination thereof. The material of the core 302 may be a single component or a mixture of components. The sheath 304 is substantially made of the masterbatch 10 of Fig. 1, so that the prepared abrasion resistant fiber can have high strength and wear resistance.

The method for preparing the abrasion resistant fiber of the present invention is, for example, performing a melt spinning process of the modified master batch of the present invention to obtain a semi-stretched yarn, and then extending the semi-stretched tow by a heated hot roll stretching machine to prepare Modified nylon fiber. However, the present invention is not limited thereto, and the modified masterbatch of the present invention may be directly subjected to a melt spinning process having a large elongation ratio to obtain a modified full-stretch fiber (FDY) modified Nylon fiber.

In other words, the abrasion resistant fiber of the present invention is thinner and tougher than conventional fibers, and has a wider application level.

Hereinafter, a comparative example and a plurality of examples will be enumerated to verify the efficacy of the present invention.

According to the different parent particle formulas 1 to 3 of Table 1 and the experimental parameters of Table 2, the fabrics of Examples 1 to 3 were woven in the loom, and then the abrasion resistance test was performed. In Comparative Example 1, the wear resistance test was carried out using a commercially available PP bag wrap.

As shown in Table 2, the abrasion resistance of the fabric made using the abrasion resistant fiber of the present invention under the ASTM D3884 test exceeded about 900 times, indicating that the abrasion resistance was good. In addition, as the amount of solid wear modifier increases, the number of wear and tear increases. As shown in the results of Examples 2 to 3, when the solid wear modifier of the abrasion resistant fiber exceeds 5 parts by weight, the number of abrasion resistance may exceed about 2,500 times. In contrast, fabrics made using only conventional PP were only 516 times resistant to ASTM D3884 testing. In addition, the fiber abrasion resistance (DPF) of the abrasion resistant fiber of the present invention is less than 4.5, and the conventional fiber abrasion resistance (DPF) of the abrasion resistant fiber is as high as 6.5 or more, so that the abrasion resistant fiber of the present invention is compared Conventional fibers can be further refined and applied at a wider level.

In summary, the solid wear modifier used in the present invention is a polysiloxane type modifier, such as ultra high molecular weight polydimethyl siloxane (PDMS), which is a solid powder. Therefore, the high-performance mixing processing and the coupling agent modification technology can be used to effectively disperse the solid wear-modifying modifier in the nylon-resistant main body, and prepare a spinning grade self-lubricating type to improve wear resistance. Long mother particles are applied. The wear-resistant fiber of the present invention can be used as an industrial fiber, which is thinner and stronger than conventional fibers, has better dyeability, and has a wider application range.
