Description

A production method for hot stamping of anodized aluminum material on non-woven fabric

technical field

The invention relates to the technical field of processing non-woven fabrics, in particular to the processing technology of non-woven fabrics with anodized aluminum hot stamping patterns.

Background technique

Nowadays, many non-woven fabrics are widely used in decoration, such as packaging gifts and flowers, but the current non-woven fabric process is opening, pre-combing, laying, main combing, laying, impregnating slurry, impregnating and rolling to remove Some of the sizing, drying, and rolling are mostly of a single color, and the variety is still single, which cannot meet the needs of the market.

Contents of the invention

The purpose of the present invention is to improve the product grade and increase the product variety, and is designed for the production method of the non-woven fabric with anodized aluminum hot stamping pattern.

The present invention comprises following processing steps:

1) Engraving a concave pattern on the surface of the pattern roller;

2) Glue the flower roller;

3) Scrape off the excess glue on the surface of the flower roll other than the concave pattern;

4) Transfer the sizing material in the concave pattern on the pattern roller to one side of the hot stamping film through the pressure roller;

5) Baking the sizing material on the gluing anodized aluminum hot stamping film to semi-drying through an oven;

6) Under the condition that the surface temperature of the pressing roller is 110-120°C, compound the non-woven base fabric on the anodized aluminum hot stamping film with a glue layer, and form a roll to form a semi-finished product;

7) Heat preservation and curing of the semi-finished product for 12±0.5 hours at a temperature of 60-70°C in a drying room;

8) After heat preservation and solidification, the anodized aluminum hot stamping film is separated from the composite non-woven fabric, and the anodized aluminum hot stamping film and the nonwoven fabric are wound up separately.

The process of the present invention is simple and easy to control production. Through the above process steps, regular gold, silver and metal laser characters and patterns that are not easy to fall off can be formed on the conventional non-woven fabric, which can be patterns or fonts, so that the variety of non-woven fabrics increases. And improve product quality. Moreover, conventional non-woven fabrics can be natural color fabrics, bleached or dyed fabrics, or random pattern fabrics, and are not limited to the above types.

The grammage of the non-woven base cloth before compounding is 25g-100g/m ² , and the grammage of the anodized aluminum hot stamping film is 20-40g/m ² . The selection of appropriate base cloth weight and appropriate amount of anodized hot stamping film can fully reflect the effect of the metal film on the base cloth, and can also make the pattern on the product more firm.

In order to facilitate control and improve product quality and production efficiency, in step 5) of the present invention, the glued anodized aluminum hot stamping film is placed in an oven at a temperature of 50-70°C.

Detailed ways

1. Production of conventional non-woven base fabrics:

The fibers are mixed and opened, pre-combed, web-laid, main combed, web-laid, impregnated with slurry, impregnated with rollers to remove part of the slurry, dried, and rolled to form a finished non-woven fabric. Bleached or dyed cloths can also be formed by conventional methods, and random patterns are also possible.

The non-woven base cloth of the present invention is made by the above-mentioned process, and the non-woven base cloth with a grammage of 25g to 100g/ ^m2 can be selected for use.

2. Prepare flower roller:

Laser engraving is used on the outer surface of the cylindrical steel roll body to make a flower roll with concave patterns or characters, ready for use.

3. Preparation of rubber materials:

The adhesive, methyl ethyl ketone and curing agent are prepared according to the conventional method to form a glue, and the glue is placed in the glue tank.

4. Select an anodized aluminum hot stamping film (namely an anodized aluminum hot stamping gold or silver foil film) with a grammage of 20-40g/ ^m2 in rolls, and set it aside.

5. Formation of non-woven fabric with anodized aluminum stamping film pattern:

Set the rubber groove under the flower roller, turn the flower roller to glue the outer surface of the flower roller, and then scrape off the excess rubber on the surface of the flower roller outside the concave pattern with a scraper, and make the concave surface of the concave pattern Keep glue.

Arrange the flower roller and an elastic pressure roller in pairs on the frame, and arrange the flower roller under the pressure roller. Transfer the rubber in the concave pattern on the pattern roller to one side of the anodized aluminum hot stamping film through the pressure roller.

Pass the glued anodized aluminum hot stamping film through an oven at a temperature of 50-70° C., and dry the glue on the glued anodized aluminum hot stamping film until it is half dry.

Under the temperature condition of 110-120 ℃, use a pair of pressing rollers with upper steel roller and lower rubber roller to compound the non-woven base fabric on the anodized aluminum hot stamping film with adhesive layer, and heat it in an oven with a temperature of 60-70 ℃ Heat preservation and curing for 12±0.5 hours.

After heat preservation and solidification, the anodized aluminum hot stamping film is separated from the composite non-woven fabric and rolled up separately.
