AI Technical Summary

Benefits of technology

The present invention is about a special type of nylon fiber and a fabric made from it. The fiber has better crimp contraction and is made up of two types of nylon fibers arranged in a way that allows for better elongation-recovery rate. This means that the fabric made from the fiber has better stretching and recovery without using synthetic elastic materials. The fiber contains a long chain polyamide and a polyether modified polyamide, which is co-polymerized by a lactam, polyether diamine, and a straight-chain aliphatic diacid. The fiber is made by using a special process that involves polymerization using a specific solvent and a specific catalyst. The fabric is made by using a combination of the special fiber and a stretch elastic material in a specific ratio. The technical effect of this invention is that it provides a better quality, more elastic fabric without using synthetic elastic materials.

Problems solved by technology

It is difficult that the structure of the existing dual-component fibers has a new breakthrough to present improved or new functions.

embodiment 1

of Nylon Side-by-Side Composite Fibers

[0017]In this embodiment, various nylon side-by-side composite fibers were obtained by melt spinning.

[0018]In examples 1-3, the long chain polyamide was nylon 6.10, and the polyether modified polyamide was copolymerized by caprolactam, polyethyleneoxy diamine, and adipic acid. The added amount and the average molecular weight of the polyethyleneoxy diamine were 8 wt %, and 2000, respectively. The weight ratios of the long chain polyamide to the polyether modified polyamide for examples 1-3 were 60: 40, 50: 50, and 40: 60, respectively.

[0019]In examples 4-6, the long chain polyamide was nylon 6.10, and the polyether modified polyamide was copolymerized by caprolactam, polybutyleneoxy diamine, and adipic acid. The added amount and the average molecular weight of the polyethyleneoxy diamine were 0.82 wt %, and 1000, respectively. The weight ratios of the long chain polyamide to the polyether modified polyamide for examples 4-6 were 60: 40, 50: 50, ...

embodiment 2

f the Nylon Composite Fibers

[0022]The weight ratios of the long chain polyamide to the polyether modified polyamide (examples 1-3 and 4-6) were respectively varied to test various properties of the obtained nylon side-by-side composite fibers.

[0023]First, crimp contraction of a protofilament was measured for the obtained nylon side-by-side composite fibers, and the measured results of the obtained nylon side-by-side composite fibers are listed in Table 2. The crimp contraction test was performed by the method described below. The length of a tested fiber loaded with a weight of 0.22 g / denier (i.e. 2 g / tex) for 10 seconds was measured to be L1. Then, the tested fiber was unloaded and kept at 160° C. for 30 minutes. Next, the length of the tested fiber loaded with a weight of 0.011 g / denier (i.e. 0.1 g / tex) for 10 minutes was measured to be L2. Accordingly, the crimp contraction (CC) is calculated by the formula (1) below.

CC(%)=(L1−L2) / L1×100%   (1)

f Nylon Fabrics Containing the Nylon Composite Fibers

[0028]In examples 4-6 and comparative examples 1-3, the above obtained nylon side-by-side composite fibers were woven to form a nylon fabric. The warps were 70d / 24f DTY, and the wefts were side-by-side 70d / 24f SDY. In examples 4-6 and comparative examples 1-3, garters woven from the nylon side-by-side composite fibers above were used. In the garters, the warp density is 92 warp / inch, and the weft density is 80 weft / inch.

[0029]Elongation-recovery rates and wear resistance were measured, and the results are listed in Table 3 below.
