Problems solved by technology

[0005] Furthermore, in the above-mentioned background technology, the water-repellent fiber / yarn prepared is washed with water for many times, and the water-repellent agent attached to the surface of the fiber / yarn is easily washed out. Specifically, according to AATCC (American Association of Textile Chemists and Colorists)-135 standard water washing about 20 times, the fiber water repellent effect will be significantly worse

Embodiment 1

[0035]The polyethylene terephthalate (A) particle and the polyethylene terephthalate (B) particle of fluorine-containing low surface energy additive (manufactured by GOULSTON company, product name FC-L624) 30wt% according to A / B=90 / 10 ratio blending, melt spinning at 288°C with a spinning speed of 2800m / min, and then a false twisting process with a coiling speed of 600m / min, a hot plate temperature of 230°C, and an elongation ratio of 1.75 (DTY ) to obtain fibers containing 3wt% low surface energy additives. The obtained fibers were woven into a fabric, and the surface tension value, water bead contact angle and water repellency test characteristics of the fabric were measured, and the results are shown in Table 1.

Embodiment 2

[0037] The polyethylene terephthalate (A) particle and the polyethylene terephthalate (B) particle of fluorine-containing low surface energy additive (manufactured by GOULSTON company, product name FC-L624) 30wt% according to A / B=90 / 10 after blending, melt spinning at 288°C with a spinning speed of 2800m / min, and then fully drawn yarn with a spinning speed of 4000m / min, an extension temperature of 85°C, a setting temperature of 130°C and an elongation ratio of 2.1 Fibers containing 3wt% low surface energy additives were prepared by manufacturing process. The obtained fibers were woven into a fabric, and the surface tension value, water bead contact angle and water repellency test characteristics of the fabric were measured, and the results are shown in Table 1.

Embodiment 3

[0039] The polyethylene terephthalate (A) particle and the polyethylene terephthalate (B) particle of fluorine-containing low surface energy additive (manufactured by GOULSTON company, product name FC-L624) 30wt% according to A / B=90 / 10 after blending, at the melting temperature of 288 ℃, the fiber containing 3wt% low surface energy additive was prepared by the HOY process with a spinning speed of 4500m / min. The obtained fibers were woven into a fabric, and the surface tension value, water bead contact angle and water repellency test characteristics of the fabric were measured, and the results are shown in Table 1.

Abstract

The present invention relates to a method for producing a low surface energy fiber having a long-term liquid repellency and anti-stain effect. The present invention relates to an addition of a specific ratio of low surface energy additives to a thermoplastic polymer used as a spinning raw material, which is subjected to spinning processing procedure, such as melting spinning, to produce fibers with a surface tension of between 25˜72 dyne / cm.

Description

technical field [0001] The invention relates to a method for manufacturing fibers, in particular to a method for manufacturing fibers with low surface energy. Background technique [0002] In the past, fabrics with low surface energy (low surface tension) functions were usually manufactured by applying low surface energy additives to the fabric, such as coating, immersion, pressure suction, etc. to make the low surface energy additives It is obtained by adhering to the fabric, and then fixing the auxiliary agent on the fabric at a heating temperature of about 100-210°C. [0003] Taiwan Patent Application No. 098110619 (hereinafter referred to as Patent Document 1) discloses a method for manufacturing water-repellent yarns. The yarns to be treated are sequentially passed through a tank filled with water-repellent agents to adhere The water agent is further passed through a heat treatment unit to fix the water repellent agent on the yarn to be treated to form a water repellen...
