Abstract
Provided are a polyethylene yarn having improved weaving properties and a functional fabric including the same, and more particularly, a polyethylene yarn which may provide a user with an appropriate cool feeling and excellent wearability and allow manufacture of a fabric having a very low fluff occurrence frequency, and a functional fabric including the same are provided. The polyethylene yarn has a polydispersity index (PDI) of 5 or more and 20 or less, a strength of 1.5 to 10 g/d as measured according to ASTM D2256, and an elongation at maximum force of 10 to 50%.
Claims10
A polyethylene yarn having a polydispersity index (PDI) of 5 or more and 20 or less, a strength of 1.5 to 10 g/d as measured according to ASTM D2256, and an elongation at maximum force of 10 to 50%,
- wherein the polyethylene yarn satisfies the following Equation 1 in a weight distribution graph by gel permeation chromatograph (GPC) analysis, with a log scale of a molecular weight (Mw) on the x-axis against a weight distribution (dw/d Log M) on the y-axis, and the weight distribution graph is unimodal:
- (

- wherein Mwaver is a molecular weight having a maximum molecular weight distribution in the weight distribution graph, Mwmax and Mwmin refer to two molecular weights corresponding to 0.25Q in the weight distribution graph, for a weight distribution value Q at Mwaver, and Mwmax refers to a maximum value of the two molecular weights and Mwmin refers to a minimum value of the two molecular weights.
