Problems solved by technology

The original polyurethane synthetic leather is hollow lotus-shaped fiber, which cannot meet the requirements in terms of hand feel and physical properties. Although the soft hand feel and high physical properties of microfiber synthetic leather meet the requirements, the brightness and wear resistance of existing products cannot meet the requirements.

Embodiment 1

[0061] Nylon-6 and polystyrene were blended and melt spun at a ratio of 1:1. The two raw materials are melted, mixed and extruded in an extruder to form a sea-island structure filament in which nylon-6 is a sea and polystyrene is an island. Let the stretched monofilament be 10-15 denier. Perform 2 extensions at 180-220 degrees, and the extension rate is 3.0-4.0 times. The multi-component mixed spinning fiber of the present invention can reach 3-5 denier by stretching, and the sea-island fiber is crimped by machinery and cut into 51mm long fiber. The island-in-the-sea fiber and nylon fiber are mixed according to the ratio of 60:40, carded into a web, and laid into a 250-300g / m 2 The cotton net is needle-punched and PVA heat-fixed to form the original fabric for processing. After wet processing such as wet polyurethane resin impregnation coating, after the polyurethane resin is solidified, the island components of the sea-island fibers are extracted with toluene to form a fib...

Embodiment 2

[0067] Nylon-6 and polyethylene were blended and melt-spun at a ratio of 55:45. The two raw materials are melted, mixed and extruded in an extruder to form a sea-island structure filament in which nylon-6 is an island and polyethylene is a sea. Assuming that the stretched monofilament is 14-20 denier, stretching is carried out twice at 50-95 degrees, and the elongation rate is 2.5-4.0 times. The multi-component mixed spinning fiber of the present invention can reach 4-8 denier by stretching, and the sea-island fiber is crimped by machinery and cut into 51mm long fiber. The sea-island fiber and polyester fiber are mixed according to the ratio of 80:20, carded into a web, and laid into a 350-450g / m 2 The cotton net is needle-punched and hot-pressed to form the original fabric for processing. After wet processing such as wet polyurethane resin impregnation coating, after the polyurethane resin is solidified, the sea-island fiber is extracted with toluene to form a fiber structu...

Embodiment 3

[0074] Mix nylon-6 slices and polystyrene slices in a ratio of 45:55, add an appropriate amount of black color masterbatch, and carry out mixed melt spinning to form black sea-island structure filaments with nylon-6 as the sea and polystyrene as islands. After spinning, it is processed into cotton type sea-island fiber. The sea-island fiber and polyester fiber are mixed according to the ratio of 60:40, carded into a web, and laid into a 350-400g / m 2 The cotton net is needle-punched and PVA heat-fixed to form the original fabric for processing. After wet processing such as wet polyurethane resin impregnation coating, after the polyurethane resin is solidified, the island components of the sea-island fibers are extracted with toluene to form a fiber structure in which hollow lotus-shaped fibers and polyester fibers coexist. The proportion of the polyurethane resin coating liquid is as follows: 100 parts of powdered polyurethane resin, 280 parts of DMF, 7 parts of coagulation mo...

Abstract

The invention relates to a mirror face synthetic leather and a manufacturing method thereof, belonging to the technical filed of synthetic leather and manufacturing methods. The manufacturing method is characterized in that the manufacturing method comprises the following steps: manufacturing polyester or daiamid short fiber and sea-island fiber into non-woven fabrics, immersing the non-woven fabrics in polyvinyl alcohol or ironing the non-woven fabrics by hot pressing, processing raw fabrics, immersing and coating polyurethane, solidifying, extracting, obtaining basic fabrics, embossing, removing film by a dry method, curing and inspecting for entering warehouses. The mirror face synthetic leather manufactured by the manufacturing method has high wearing resistance, high brightness, excellent performance and technological improvements on base layers and surface layers, effectively develops the use valve that the original single sea-island fiber does not have, and combines the characteristics of sea-island fiber and daiamid or polyester fiber. The manufacturing method widens the technical routes of synthetic leather development and has wide prospects of popularization and application.

Description

1. Technical field [0001] The invention relates to mirror synthetic leather and a manufacturing method, belonging to the technical field of synthetic leather and manufacturing methods. 2. Background technology [0002] At present, after years of development, polyurethane synthetic leather is widely used in various industrial and civil fields because of its good appearance and feel, breathable moisture permeability, solvent resistance, convenient application, and many varieties of colors. In recent years, with the demand for new materials for military refitting, polyurethane synthetic leather products and microfiber synthetic leather have been used more and more in military products. The original polyurethane synthetic leather is hollow lotus-shaped fiber, which cannot meet the requirements in terms of feel and physical properties. Although the soft feel and high physical properties of microfiber synthetic leather meet the requirements, the brightness and wear resistance of e...
