Example

[0050] Example 1

[0051] Polyethylene terephthalate is used as the basic polymer to prepare a masterbatch, the masterbatch includes 15% by weight of polytetrafluoroethylene particles, the average particle size of the polytetrafluoroethylene particles measured by an electron microscope The diameter is 0.5 μm.

[0052] Using the prepared masterbatch and the basic polymer polyethylene terephthalate, a polyethylene terephthalate fiber including 36 single fibers of 75 denier is produced through spinning and direct drawing processes. By adjusting the content of the masterbatch, the content of polytetrafluoroethylene particles in the fiber is controlled at 1% by weight.

[0053] 88 strands of fiber are produced in a drum with a capacity of 4kg, knitted with a double rib circular knitting machine with a gauge of 22, and dyed at 130°C for 60 minutes, and dried with a hot air dryer at a rate of 30m / min for production Circular knitted fabric.

Example

[0055] Example 2

[0056] A polyethylene terephthalate fiber and a circular knitted fabric including the same were prepared by the same process as Example 1, except that the average particle diameter of the above-mentioned polytetrafluoroethylene particles was changed to 1.0 μm and the polyethylene terephthalate The content of particles in the fiber was changed to 2%.

[0057] The measurement results of the abrasion resistance times of the fabrics produced are shown in Table 1.

Example

[0058] Example 3

[0059] Under the same conditions as those described in Example 1, a circular knitted fabric was produced by using a false twisted yarn based on polyethylene terephthalate, wherein the circular knitted fabric was produced under the same conditions as those described in Example 1. The obtained polyethylene terephthalate fiber (containing 1% by weight of polytetrafluoroethylene in the fiber) is false-twisted to prepare the false-twisted yarn.

[0060] The measurement results of the abrasion resistance times of the fabrics produced are shown in Table 1.

Abstract

Disclosed are a thermoplastic fiber with excellent durability and a fabric comprising the same. More particularly, the thermoplastic fiber contains fluoropolymer particles with average particle diameter ranging from 0.01 to 5.0/[Mu]m in thermoplastic resin to form the fiber. The inventive thermoplastic fiber is prepared by adding the fluoropolymer particles to the thermoplastic resin while spinning the thermoplastic resin. The inventive thermoplastic fiber exhibits superior durability, that is, resistance to friction and/ or modification and is preferably adopted as yarns for footwear, furniture, (mountain-climbing) backpacks, abrasives, sportswear and so on.

Description

technical field [0001] The present invention relates to a thermoplastic fiber having good durability and a fabric comprising the thermoplastic fiber, more particularly, to a thermoplastic fiber having good durability against friction and / or transformation and a fabric comprising the thermoplastic fiber, The thermoplastic fibers contain fluoropolymer particles having an average particle diameter in the range of 0.01 to 5.0 μm in a thermoplastic resin used to form the fibers. Background technique [0002] In order to increase the durability of thermoplastic fibers made of nylon and / or polyethylene terephthalate, the following methods known in the prior art are mainly used. [0003] The first is to improve the mechanical properties of the yarn itself by increasing the molecular weight of the base resin used for thermoplastic fibers during polymerization. [0004] The second method is to increase the basic thickness of the thermoplastic fiber bundle during spinning of the yarn,...
