Description of the invention () The present invention is to provide a high-strength artificial leather and its manufacturing method. Effect, and has the disadvantages of light weight and low elongation. In the past, artificial leather used to make covers, clothing, shoes, chair covers, purses and the like was mainly made of natural fibers (natural fibers or synthetic fibers, such as polyester cotton) or ultrafine fibers (such as Poly-brew / nylon sea island persimmon) to form a non-woven fabric, and then add an elastic polymer (such as polyurethane) to form a substrate. In order to promote the artificial leather substrate in terms of appearance, touch, and ochre properties, able dogs have achieved better results. The conventional improvement methods are based on fiber surface research and development, and have a cost-effective effect. However, it only has excellent appearance and touch, and it can not really improve the quality of artificial leather. It must still have high strength and light weight. It is a high-quality product to facilitate the manufacture of various leather products. The use of the present invention is both to develop a Θ that can provide a high-strength and lightweight artificial leather. The artificial leather prepared according to the method of the present invention will have the characteristics of light weight, high peel strength, high breaking strength, and low elongation under the same specifications as conventional products of the same type, except that it does not affect the appearance or feel of the leather. 'It is used to make gloves, clothing, shoes, bags, leather bags, sofas, chair covers, balls and the like, and can achieve quality improvement. The present invention mainly focuses on the adhesion of at least one of the ordinary woven and fine fibers, and the fiber assembly is consolidated to form a fiber assembly gift. The fiber assembly is then filled with a gas-formate (PU) composition * To form an artificial leather substrate, and then grind or embossed or release paper (or form an F »U layer with micropores on at least one side of the artificial leather substrate), and then grind or engrave or apply -3--^ W3 (Please read the notes on the back before filling this page) -'β This paper size is applicable to China National Standards (CNS) A4 format (210 × 297 mm).
