Problems solved by technology

In the past, in order to achieve this purpose, low-modulus polyurethane resins were generally used. Because the superfiber in the present invention adopts the toluene fiber opening process, the low-modulus polyurethane resin has a large corrosion rate and the cells are easy to collapse during the process of toluene fiber opening. etc., the softness of the prepared microfiber synthetic leather is relatively good, but it has the disadvantages of poor myogenesis, weak fleshy feeling, thick creases, etc., which reduces the economic benefits and makes its cost high. The corrosion rate is high, and a large amount of polyurethane components enter the crude toluene, which leads to easy blockage of pipes and evaporators during the toluene recovery process. At the same time, the purity of waste polyethylene particles is greatly reduced, which reduces the recovery value of waste polyethylene and reduces the cost of recycling equipment. usage time

Abstract

The invention belongs to the technical field of preparation of ultrafine fiber synthetic leather, and in particular relates to a preparation method of ultrafine fiber sofa leather bass, comprising the following processing steps: spinning, non-woven fabric, non-woven fabric shaping, wet impregnation, extraction, and drying Oiling, kneading and finishing. The preparation method of the present invention adopts novel polyurethane to wet impregnate the microfiber non-woven fabric, and is equipped with a reasonable superfiber production process, so that the microfiber bass prepared by the present invention has the characteristics of plump flesh and relatively delicate creases, and can be Improve the grade of microfiber sofa leather, comparable to calfskin and goatskin, greatly reduce the consumption of raw materials, increase the recycling value of waste polyethylene, and improve product quality, and the economy is relatively high.

Description

Technical field[0001]The present invention belongs to the preparation of beam-shaped ultra-fine fibers, and specific methods for the preparation of Khmer Skin Soft Sofa Revolution.Background technique[0002]Ultrafine fiber synthesis leather (referred to as ultra-film) is a high-end artificial leather that develops on the basis of natural leather. It is formed by the bundle ultrafine fibers and polyurethanes. It is based on the nylon 6 microfibers as a three-dimensional stereo "skeleton", and the polyurethane is "meat", closely wrapped in the "skeleton" structure, with an irregular sponge structure . Bes' microstructure is similar to the collagen fibers of natural leather, and also has similar tissue structures and physical chemical properties similar to natural leather. The microfiber leather has almost all characteristics and advantages of natural leather, and is better than natural leather in terms of mechanical strength, chemical resistance, unity, protection, automated cutting, a...
