The bast fibers include flax, ramie, jute & hemp. Linen fabrics have a course, natural-looking texture, and a slight sheen. Quite insightful. Other sources lay claim to the earliest usage of flax to be in the Stone Age. Publisher - a knowledge-base repository of textile articles. These broken flaxes are called ‘cottonized’ flax. It can also shrink and soften if Linen also has poor elasticity – it tends to stretch without recovering its shape. Flax: Like cotton, flax fibre is a cellulose polymer, but its structure is more crystalline, making it stronger, crisper and stiffer to handle, and more easily wrinkled.Flax fibres range in length up to 90 cm, and average 12 to 16 microns in diameter. A common feature of natural fibers is a much higher variability of mechanical properties. Laboratory triaxial tests were carried out to investigate the reinforcement mechanism, to study the characteristics of flax fiber-reinforced clay, and to discuss the effect on stress-strain relationship and shear strength parameters of flax fiber-reinforced clay in different flax fiber content and different confining pressure. it is considered to be a heavy fiber, for this reason that most linen textile materials are of light construction. Planting. Textiles in a Linen weave texture, even when made of cotton, hemp, and other non-flax fibers, are also loosely referred to as “linen”. Raw materials that we get from flax can be applied in bio-polymers, aerospace and automotive industries as well as for production of agro fine chemicals. It also has various applications. However, since environmental-friendly products have become more popular, flax has regained its place in the industry, being used again for linoleum flooring due to its biodegradable and non-allergenic characteristics.
