How to choose canvas? What are the characteristics of canvas?

According to the material can be divided into: linen canvas, cotton canvas, chemical fiber canvas, cotton canvas and other materials of canvas.

Canvas: A substrate coated with a coating that prevents the penetration of oil, solvents, water, etc., used for painting oil paintings.

Coated cloth for spray painting, photo, indoor and outdoor advertising, light boxes, etc., also known as canvas.

Performance requirements

Hand-painted canvas: stable size, strong elasticity, clear texture, no cracking, durable, good weather resistance, smooth and flat, impact resistance, few pores, special organization, which can meet the requirements of oil painting creation, collection and preservation.

Spray painting canvas: smooth and smooth, gloss, cloth pattern, coating fastness, coating pinhole, curl, water resistance.

Indoor and outdoor advertising, light box cloth and other requirements of solid substrate, coating weather resistance.

Material identification

The canvas generally does not need to be bleached and dyed, which can seriously compromise its strength and durability.

High strength, small elongation, corrosion resistance, not easy to mildew, anti-fouling, fast moisture, etc. Linen fabric is a kind of traditional excellent oil canvas substrate, which is stable in size and durable. According to the different processing methods of making hemp fiber, there are bright yellow warm water flax (water immersion degummed flax) and blue gray rain flax (field wind and rain frost dew retting flax). Because of its coarse texture and more hair, it is not suitable for spray painting.

Yulu hemp is a high-quality flax, which refers to the flax cultivated and produced in France, the Netherlands, Belgium and other Western European regions. After the mature harvest, the flax seedlings are rolled into bundles and placed in the field. After being treated by rain, wind and frost, the wood in the middle of hemp stem rotted, and the hemp fiber in the phloem of blue-gray cortex was obtained by squeezing and combing.

Flax size stability, high strength, moisture resistance, corrosion resistance, mildew, not easy to save for a long time, elongation is very small, rarely loose under the action of force, light and flexible, impact resistance, buffer external force, in line with the expansion of the paint layer, can be rolled up. It is superior to other materials, is suitable for oil painting creation of the substrate. Linen canvas has been used for hundreds of years.

In the use of cotton canvas for hand-painted, due to the perishable cotton, moisture is not easy to dry and other shortcomings, the shortcomings of continuous relaxation, to the painter brought a lot of trouble.

Chemical fiber (polyester) has excellent performance as a canvas, but its disadvantage is that embrittlement may occur in the future, and the fabric does not have the texture that the painter likes. Suitable for spray painting canvas to use.
