Embodiment 1

[0024] An ultra-real ecological leather, composed of sea-island filaments, water-based resin, and polyurethane, of which sea-island filaments account for 92% by weight, and the balance is water-based resin and polyurethane (the ratio of the two is 6.5︰3.5). Among them, the sea-island filament consists of two specifications: 70D and 30D.

[0025] The manufacturing process of super genuine ecological leather of the present invention comprises the following steps:

[0026] (1) Sea-island filaments are used as raw materials to warp-knit gray fabrics; among them, sea-island filaments are warp-knitted by combining a sea-island filament with a specification of 70D and a sea-island filament with a specification of 30D as raw materials; (2 ) pre-shrink the gray cloth; (3) carry out alkali reduction fiber opening; (4) carry out neutralization treatment; (5) carry out the first drying treatment; (6) carry out the first water grinding treatment; (7) use Dyeing with imported high-...

Embodiment 2

[0041] A kind of ultra-real ecological leather, which is composed of sea-island filament, spandex filament, water-based resin and polyurethane, wherein the weight percentage of sea-island filament is 88%, spandex filament is 5%, and the balance is water-based resin and polyurethane (the ratio of the two is 6.5︰3.5). Among them, the sea-island filament consists of two specifications: 70D and 30D.

[0042] The manufacturing process of super genuine ecological leather of the present invention comprises the following steps:

[0043] (1) Sea-island filaments are used as raw materials to warp-knit gray fabrics; among them, the sea-island filaments consist of a sea-island filament with a specification of 70D and a composite yarn with a specification of 30D, and the specification of the spandex yarn is 70D; (2) Pre-shrink the gray cloth; (3) Perform alkali reduction and fiber opening; (4) Perform neutralization treatment; (5) Perform the first drying treatment; (6) Perform th...

Embodiment 3

[0058] A kind of ultra-real ecological leather, which is composed of sea-island filament, spandex, water-based resin and polyurethane, wherein the weight percentage of sea-island filament is 85%, spandex is 6%, and the balance is water-based resin and polyurethane (both The ratio is 6.5︰3.5). Among them, the sea-island filament consists of two specifications: 70D and 30D.

[0059] The manufacturing process of super genuine ecological leather of the present invention comprises the following steps:

[0060] (1) Sea-island filaments and spandex yarns are used as raw materials to warp-knit gray fabrics; among them, sea-island filaments are composed of a sea-island filament with a specification of 70D and a sea-island filament with a specification of 30D as raw materials. (2) pre-shrink gray cloth; (3) carry out alkali reduction and fiber opening; (4) carry out neutralization treatment; (5) carry out the first drying treatment; (6) carry out the first water grinding treatm...

Abstract

The invention relates to high-emulation ecological leather and a manufacturing technology of the high-emulation ecological leather and belongs to the technical field of textile fabric. The high-emulation ecological leather is composed of island filaments, water-base resin and polyurethane, wherein the high-emulation ecological leather comprises, by weight, 92% of island filaments and the balance water-base resin and polyurethane. The high-emulation ecological leather can also be composed of island filaments, spandex, water-base resin and polyurethane, wherein the high-emulation ecological leather comprises, by weight, 75% to 88% of island filaments, 5% to 11% of spandex and the balance water-base resin and polyurethane. The high-emulation ecological leather manufactured according to the manufacturing technology has the advantages that the gram weight is large, the density is high, the leather emulation performance is high, the drapability is high, poisonous matter residuals are avoided, and the characteristics that knitted fabric is high in bursting strength and high in tearing strength remain. In addition, by the adoption of the manufacturing technology of the high-emulation ecological leather, water is saved, and environmental friendliness is achieved.

Description

technical field [0001] The invention relates to a super genuine ecological leather and a manufacturing process thereof, belonging to the technical field of textile fabrics. Background technique [0002] Ecological leather is one of the more popular high-grade fabrics in the domestic and foreign markets. But the artificial leather property of existing imitation leather fabric is not strong, and drapability is poor. At the same time, during the processing and manufacturing of imitation leather fabrics and genuine leather, due to the use of various chemicals such as fillers and replacement agents, a large amount of waste water will be generated in the later stage, including hexavalent chromium, formaldehyde, DMF and other toxic and harmful substances. Like this, not only cause environmental pollution, bring high cost to environmental treatment, and this kind of substance is easy to remain on fabric, causes harm to human body. Contents of the invention [0003] The purpose o...
