Embodiment 1

[0061] A kind of production technology that utilizes numerical control cutting machine to prepare leather, comprises the following steps:

[0062] (1) Material selection: use sheepskin, pigskin or cowhide leather as the embryo;

[0063] (2) Draw patterns: draw patterns through the computer of the CNC cutting machine, and output the patterns;

[0064] (3) CNC cutting: Use a CNC cutting machine to cut out the pattern of natural reptiles on the surface of the leather to obtain the leather.

[0065]In the step (2), the output pattern is a high-resolution image with a resolution of 1000 L / cm.

[0066] In the step (3), the process parameters of the CNC cutting machine are: the power frequency is 40 Hz, the engraving width is 5 μm, the cutting depth is 0.1 mm, and the cutting speed is 300 mm / s.

[0067] After the step (1), it also includes step (11) scraping and repairing: use a scraper to scrape and fill the repairing ointment on the surface of the skin embryo, put the scraped ski...

Embodiment 2

[0100] The difference between this embodiment and above-mentioned embodiment 1 is:

[0101] In the step (2), the output pattern is a high-resolution image with a resolution of 1500 L / cm.

[0102] In the step (3), the process parameters of the CNC cutting machine are: the power frequency is 50 Hz, the engraving width is 8 μm, the cutting depth is 0.15 mm, and the cutting speed is 400 mm / s.

[0103] After the step (1), it also includes step (11) scraping and repairing: use a scraper to scrape and fill the repairing ointment on the surface of the skin embryo, put the scraped skin embryo into an oven to dry and shape it, and use a roller to smooth the skin The embryo is pressed flat, the drying temperature is 80°C, and the drying time is 8 minutes.

[0104] Described repairing ointment comprises the raw material of following weight portion:

[0105] 60 parts of water-based polyurethane emulsion

[0106] Heat-expandable hollow microspheres 15 parts

[0107] Silicone resin emuls...

Embodiment 3

[0136] The difference between this embodiment and above-mentioned embodiment 1 is:

[0137] In the step (2), the output pattern is a high-resolution image with a resolution of 2000 L / cm.

[0138] In the step (3), the process parameters of the CNC cutting machine are: the power frequency is 60 Hz, the engraving width is 10 μm, the cutting depth is 0.2 mm, and the cutting speed is 500 mm / s.

[0139] After the step (1), it also includes step (11) scraping and repairing: use a scraper to scrape and fill the repairing ointment on the surface of the skin embryo, put the scraped skin embryo into an oven to dry and shape it, and use a roller to smooth the skin The embryo is pressed flat, the drying temperature is 100°C, and the drying time is 10 minutes.

[0140] Described repairing ointment comprises the raw material of following weight portion:

[0141] 80 parts of water-based polyurethane emulsion

[0142] 20 parts of heat-expandable hollow microspheres

[0143] Silicone resin ...

Abstract

The invention relates to the technical field of leather processing, and specifically relates to a production process for preparing leather by virtue of a numerical control cutting machine. The production process comprises the following steps: (1) material selection: using sheepskin leather, pigskin leather or calfskin leather as a crust; (2) pattern drawing: drawing a pattern through a computer of the numerical control cutting machine, and outputting the pattern; and (3) numerical control cutting: cutting the lines of reptiles in the nature on the surface of the leather through the output pattern by the numerical control cutting machine, so as to prepare the leather. The production process disclosed by the invention has simple steps, and is convenient to operate and control, stable in quality and high in production efficiency; the raw materials are low in price and easily available; and the leather is high in utilization rate, low in production cost, and capable of realizing large-scale industrialized production. The quality of the prepared finished leather is similar to that of top-layer leather, the additional value of the finished leather is greatly increased, and the finished leather is wide in application range and high in economic benefit.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to a production process for preparing leather by using a numerical control cutting machine. Background technique [0002] Leather is widely used on the surface of daily necessities, such as tables and chairs, sofas, shoe materials, clothing, etc., to add texture, beauty or durability to daily necessities. Leather can be broadly classified into artificial leather and natural leather. Natural leather refers to taking animal fur and drying, cleaning, softening, dyeing, trimming, cutting and other production processes to form a smooth surface and tough texture. [0003] Due to insufficient fineness and poor gloss, the existing sheepskin, pigskin or cowhide can only be used to make the inner lining of the leather, and cannot be used as the surface material of the product. The benefit is not high. Contents of the invention [0004] In order to overcome the disadvantages an...
