Background technique

With the continuous improvement of people's living standards and tastes of life, people began to decorate beautiful homes by themselves. Embroidery is one of the ancient cultures of the Chinese nation. Now it has integrated into our lives with a new look and a modern atmosphere. Embroidery works Decorate the home beautifully and elegantly. The fabrics used in traditional embroidery base fabrics are: cloth and silk materials, which have a single purpose, and the embroidery made can only be used as collectibles, gifts, anti-corrosion, waterproof, moisture-proof, mildew-proof, anti-corrosion Moth resistance and so on.

Embroidery handicrafts are decorative fabrics that use needles to puncture silk threads, yarns or other fibers on fabrics, non-woven fabrics and other processable materials into colorful and refined patterns, and use stitches to form decorative patterns. Embroidery handicrafts are one of the traditional Chinese folk handicrafts, which can be applied to daily necessities such as clothing, bedding, and tablecloths, or hung in public places, stages, or bedrooms and living rooms at home as artistic decorations. Embroidery crafts enjoy a high reputation at home and abroad, and have become one of the representatives of Chinese culture and art. Embroidery is a very cumbersome and complicated process. It is even more difficult to embroider lifelike and vivid embroidery. The existing embroidery is two-dimensional. Even if the effect of changing the viewing angle makes the embroidery have a certain three-dimensional effect, but traditional embroidery crafts generally use a single layer of fabric as the base to embroider on it, and the obtained crafts can only be a two-dimensional plane style, which is relatively monotonous and cannot make the embroidery lifelike and vivid. The effect cannot meet the growing demands of consumers.

Embroidering colorful three-dimensional patterns on cloth is a traditional handicraft of my country, but handmade cannot meet the needs of people's growing material and cultural life. With the development and progress of science and technology, the embroidery process has gradually developed from manual embroidery to mechanized and computerized embroidery through the research and development of a large number of technicians. One of the embroidery processes is this: superimpose colored cloth on the base cloth, and manually Or the machine embroiders patterns such as flowers, and then cuts off the excess color cloth, so that a beautiful color embroidery pattern is formed on the base cloth. In this process, the cutting of the excess color cloth can be manually cut, but any With the development of computer technology and the application of laser technology, the cutting process has also begun to be completed by the computer laser cutting process.
