Description

Gilt PU of imitative breathes leather

Technical Field

The utility model belongs to the technical field of the synthetic leather technique and specifically relates to a imitative gilt PU breathes leather.

Background

Leather has been widely used in the interior trim of shoes, clothes, bags, furniture, sofas, belts, automobiles, ships, airplanes and other vehicles, and is an ideal leather substitute product. With the continuous improvement of living standard and environmental protection consciousness, the quality requirement, the environmental protection requirement and the comfort requirement of people on the artificial leather are higher and higher. Although the dermis has great advantages in air permeability, softness and skin-friendly feeling, the construction of a harmonious society, animal protection and environment protection are called for globally, and the dermis pollutes the environment seriously in the production process and the heavy metal content is easy to exceed the standard. In addition, the yield is low in the processing process, so that the manufacturing cost is high, and the product is difficult to be accepted by middle-low-grade consumer groups. At present, the synthetic leather is mainly made of polyurethane resin (PU) and elastic polyvinyl chloride (PVC) sol, the two materials are petroleum products, the biggest defect is that the synthetic leather is not breathable, and the synthetic leather has adverse effects on human skin and respiratory tracts. Therefore, the manufacturing of the artificial leather with strong air permeability, environmental protection, comfort, softness and high quality becomes a research and development task in the field of artificial leather production.

Gold stamping is to stamp the golden aluminum foil film on the fabric through heat transfer, and the golden aluminum foil film has the highest glossiness, is smooth to touch and has texture. The disadvantages are high cost, slow production speed and generally not applicable to large area.

The gilding imitation printing is a process for printing a substance which is similar to pearl glittering light on a fabric in order to make fabric printing stocks have dazzling and scanning luminous effects under the condition of sufficient sunlight or light. The process is characterized in that a titanium film is used as a medium, a special substance of carbon dioxide is coated, and a brightener is coated to ensure that the refractive index reaches 3.6. The titanium dioxide has good intermiscibility with chemical substances such as clothing additives, acid resistance, high temperature resistance, good hand feeling and good flashing effect, and the prepared gilding paste has good stability and can not become dark after being exposed in the air for a long time. The gilding-imitating printing technology is popular in the market due to the excellent characteristics of simple operation method, energy conservation, no pollution, clean production and the like.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example one

This embodiment will be described in detail with reference to fig. 1 and 2. The gilt PU of imitative that this embodiment relates breathes leather, includes base cloth layer, PVC foaming resin layer, PU foaming resin layer and imitative gilt line layer.

In this embodiment, the base fabric layer is a moisture-absorbing and sweat-releasing fabric. The moisture absorption and sweat releasing fabric is woven fabric or warp knitting fabric prepared from moisture absorption and sweat releasing filaments, and the surface density is 200-300 g/square meter. The moisture absorption and sweat releasing filament is made of terylene, and the titer is one or more of 50D/72F, 100D/144F, 150D/144F, 75D/72F, 75D/48F, 75D/36F, 100D/72F, 100D/48F, 150D/96F and 150D/48F. In this embodiment, the warp knitted fabrics are 75D/72F and 100D/144F. The moisture absorption and sweat releasing fiber utilizes the capillary phenomenon generated by the micro-grooves on the surface of the fiber to ensure that sweat rapidly migrates to the surface of the fabric and is diffused through the actions of wicking, diffusion, transmission and the like, thereby achieving the purpose of moisture conduction.

In this embodiment, the thickness of the PVC foam resin layer and the PU foam resin layer is 0.1-0.5 mm. The PVC foaming resin layer and the PU foaming resin layer are provided with breathable micropores. The air-permeable micropores can be round or regular polygon and are arranged in array.

In this embodiment, the gilt-like texture layer is located on the PU foam resin layer. The PVC foaming resin layer is compounded with the bottom cloth layer. And a superfine non-woven fabric is arranged between the PVC foaming resin layer and the PU foaming resin layer. The superfine non-woven fabric has an area density of 80-100 g/m, and is spun-laced superfine non-woven fabric, preferably 100 g/m. The spunlace nonwoven fabric has more gaps inside the nonwoven fabric, and the superfine fibers also have good moisture absorption effect.

In this embodiment, a bronzing-like grain layer is further disposed on the PU foam resin layer. The gilding-imitating printing technology is a printing technology which prints on a fabric and emits glittering luster under the shining of sunlight or strong light. This process may be used to replace the pattern formed on the fabric by the gold stamping process. The gold stamping process is to stamp the golden aluminum foil film on the fabric through heat transfer, and has high glossiness, and the defect that the PE film is adopted, so that the waste of the PE film and the environmental pollution are caused. The gilding imitation process is simple, and the printing can be formed in one step. The gold stamping process is relatively complex because the gold stamping slurry is printed and printed firstly and then is heated and transferred for gold stamping. The gold stamping imitation process is environment-friendly, and the pollution of the PE film to the environment is not left. And the washing fastness of the gilding-like printing process is greatly superior to that of the gilding-process printing lines. After 4-5 times of water washing, the gilding-like printing of the fabric is basically unchanged. And the gilding imitation can generate transition color during printing, and the color tone can be randomly adjusted at high speed during printing.

Example two

This embodiment will be described in detail with reference to fig. 3. The difference between this embodiment and the first embodiment is: a layer of mesh cloth woven by nylon filaments is arranged between the bottom cloth layer and the PVC foaming resin layer, and the surface density of the mesh cloth is 5-10 grams per square meter. The nylon mesh cloth is arranged to enhance the strength of the breathing leather related to the embodiment, particularly the fracture strength of the seam.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
