Experimental example: testing of fabric Properties

In this experimental example, a heat-treated cloth was subjected to a property test. The cloth is a double-layer fabric with the specification of 26G 54' and 300G/yd. One layer of the double-layer fabric is woven by polyester yarn, and the other layer is woven by the low-melting-point polyester fiber only or by the polyester yarn and the low-melting-point polyester fiber. The low-melting polyester fiber was Spun Drawn Yarn (SDY) with a fiber size of 75d/24 f. The setting temperature in the heat treatment was 180 ℃ and the setting time was 40 seconds. The fabric was tested for a characteristic warmth retention value (CLO) (according to ASTM D1518-1985 fabric thermal conductivity test method), a water repellency (according to AATCC 22 standard method), a water repellency (according to CNS 14801 fabric water repellency test method), an abrasion resistance (according to CNS 12915L3233-2010 fabric abrasion resistance test method), and a softness (according to CNS 13752 standard method), and the results are given in the following table one.

Watch 1

From the above table one, it can be seen that, as the content of the low-melting-point fiber is higher, the abrasion resistance of the fabric can be improved, the water permeation amount in the waterproofness test can be reduced, and the number of stages of water repellency can be increased.

Although the present invention has been described in considerable detail with reference to certain embodiments, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.

It will be apparent to those skilled in the art that various modifications and variations can be made in the structure of the present invention without departing from the scope or spirit of the invention.
