Embodiment 1

[0022] A kind of technological process of the described synthetic leather of claim 1 is soft wrinkle soft high resilience bass, comprises the steps:

[0023] S1. Coat the foaming slurry on the double-sided imitation leather fabric. The longest fluffing of the double-sided imitation leather fabric is 0.25mm, the shortest middle area of ​​the cross-section is 0.3mm, and the fluffing of the bottom is 0.1mm. Foam the slurry Configuration: add 4 parts of solvent, 0.03 part of cell regulator, 0.07 part of penetrant, 0.1 part of water-based color paste, 1 part of synthetic fiber powder and 4.6 parts of low modulus super soft polyurethane resin in a stirring state, and vacuumize (to prevent The generation of bubbles when the paint is solidified) 90min, the viscosity is 10000CPS / 25℃.

[0024] S2. Cleaning the base fabric: Add the solution into the water tank, put the extra-long wool imitation leather base fabric into the solution tank through the fabric guide frame, and clean it at roo...

[0034] A kind of technological process of the described synthetic leather of claim 1 is soft wrinkle soft high resilience bass, comprises the steps:

[0035] S1. Coat the foaming slurry on the double-sided imitation leather fabric. The longest fluffing of the double-sided imitation leather fabric is 0.35mm, the shortest middle area of ​​the cross section is 0.2mm, and the fluffing of the bottom is 0.1mm. Foam the slurry Configuration: add 4 parts of solvent, 0.03 part of cell regulator, 0.07 part of penetrant, 0.1 part of water-based color paste, 1 part of synthetic fiber powder and 4.6 parts of low modulus super soft polyurethane resin in a stirring state, and vacuumize (to prevent The generation of bubbles when the paint is solidified) 90min, the viscosity is 10000CPS / 25℃.

Abstract

The invention provides a soft, wrinkled and high-resilience base for synthetic leather, and relates to the field of synthetic leather preparation. The base cloth is coated with low-modulus resin slurry, the base cloth is double-sided micro extra-long imitation leather velvet fabric with the thickness of 0.65 mm, the low-modulus resin slurry is a foaming slurry, the numbers of the warp yarn and theweft yarn of the double-sided imitation leather velvet fabric are different, the difference of the numbers is large, the fluffing lengths of the double-sided imitation leather velvet fabric are different, the large fluffing length surface of the double-sided imitation leather velvet fabric is the upper surface, the sections of the double-sided imitation leather velvet fabric are arranged in the shapes of a positive isosceles trapezoid and a reverse isosceles trapezoid in sequence, the fluffing lengths of the upper surface of the double-sided imitation leather velvet fabric are different, so that fluff on the upper surface forms a plane, and the fluff on the lower surface of the double-sided imitation leather velvet fabric is shorter than 0.1 mm. The base cloth used in the invention is improved on the basis of the traditional imitation leather velvet fabric, so that the fluffing length of one surface is increased, and the fluffing feeling is softer than that of common fabric, the handfeeling of the fabric is more plump, smoother and more elastic.

Description

technical field [0001] The invention relates to the technical field of synthetic leather preparation, in particular to a soft crepe soft high-resilience bass for synthetic leather. Background technique [0002] Advanced polyurethane resins are widely used in synthetic leather, adhesives, foams, pressure sensitive adhesives, paints and coatings, etc. Polyurethane synthetic leather has the advantages of good texture, wear resistance, high peel strength and good elasticity, and is gradually replacing the position of genuine leather in the market. The main types of synthetic leather on the market are: high / low resilience, hydrolysis resistance, no yellowing, no cells and imprinted discoloration, etc. Super soft synthetic leather is not common in the market, but downstream tanneries have shown strong interest in super soft synthetic leather. [0003] Many synthetic leather products on the market feel hard, with stiff and rigid lines and poor elasticity. Contents of the inve...
