Embodiment 1

[0022] 1. The non-woven fabric is infiltrated with 4050 wet-process polyurethane of 3000CPS in the impregnation tank to obtain the rough surface, and the other layer is fully infiltrated by pressing 5020 wet-process polyurethane of 9000CPS through multiple pressure rollers in the impregnation tank to obtain dense Floor.

[0023] 2. The high-solid imitation leather base fabric was overflow dyed at 105 degrees for 70 minutes to obtain the dyed base fabric;

[0024] 3. Dry the dyed base cloth, and use 240-mesh sandpaper when the dried base cloth is buffed and brushed;

[0025] 4. The base cloth after buffing and brushing is soaked in the oil tank by impregnation, the pressure and gap of the pressing roller are adjusted to control the liquid-carrying rate at 45%, and it is dried in an oven at 120 degrees. The softener is Nanjing Gutian 890RZ, and the proportion of softener used is 15%;

Abstract

The invention discloses a high-solid artificial leather superfine fiber base cloth and a post-treatment manufacturing method thereof. The high-solid artificial leather superfine fiber base cloth prepared sequentially through the steps of high-solid artificial leather primary base cloth preparation, high-solid artificial leather primary base cloth dyeing, leather grinding and napping treatment, softening treatment and grain treatment has good hand feeling, high softness, fine creases and leather-like velvet texture at the back side, and the fineness performance of the whole is excellent. The softness is greater than or equal to 5.5 mm (the test standard is ISO17235:2002), and the tear strength in both the transverse direction and the longitudinal direction is greater than 70 N (the test standard is GB/T8948-2008).

Description

technical field [0001] The invention relates to the field of high-solid imitation leather, in particular to a method for post-processing and manufacturing high-solid imitation leather superfine fiber base cloth. Background technique [0002] Natural leather is widely used in all aspects of life due to its durability, excellent texture and good ventilation. However, with the continuous reduction of human natural resources and the continuous promotion of environmental protection concepts, the application of natural leather will be less and less. [0003] Due to the continuous progress and development of microfiber synthetic leather in recent decades, its appearance and performance have been comparable to natural leather, and even surpassed natural leather in some functional aspects. Therefore, microfiber synthetic leather has been fully applied and developed in all walks of life. [0004] However, microfiber synthetic leather still has defects in hand feel and appearance. Wh...
