Cultivated silk is the finest, most elastic and most durable of all natural textile fibres. The filament of silk is stronger than steel wire of the same diameter and can be considerably stretched without breaking. Its remarkable strength in comparison with its diameter permits of a very strong, light and durable fabric being made. It is especially priced for its brilliant luster, elasticity and beauty.

Silk is produced by the silk worm in spinning a cocoon. The worm changes its colour to a semi-transparent pink, and from a hole in its lower lip the silk thread begins to appear. Then by a waving motion of the body the worm gradually envelopes itself in a cocoon of silk which is drawn out in a double thread, slightly twisted, and covered by silk gum. Once the silk worm starts spinning it never leaves off until the silk is exhausted. The total length of silk given out is about 500 yds.

On enveloping itself in the cocoon and on giving out its silk, the worm commences to change from worm to chrysalis, and then to moth. This takes about two or three weeks. After being fully formed, the moth eats its way out of one end, dries its wings in the sun, then flutters about. On leaving its cocoon the moth lays its eggs on a leaf and dies. The eggs hatch into silk worms and the process begins again.

1. Flax is also a vegetable fiber. It is used for manufacturing linen and linen thread. The flax fiber is recovered from the inner stem of the plant. This is in marked contrast to cotton, which is obtained from the boll of the cotton plant. The recovery of the flax fibers appears to be much more difficult and involves greater expense. The commonest form of recovery is known to be “retting”. The harvested plants are steeped in water for some time until, through the action of fermentation, the fibers can be readily separated from the woody stem and outer bark. The vegetable gum is dissolved by the action of moisture and heat.

2. All unwanted parts of the plant are than mechanically removed, leaving only the flax fibers. These fibers are made up of numerous filaments, which when separated constitute the raw fibers for manufacture. They range in length from an inch upward and are comparatively fine and strong. The colour of the fibers at this stage is not white.

3. Flax is grown extensively for many centuries in nearly every country in Europe. Russia, Ukraine, Belarus, Poland are known to be the leading flax-producing countries in the world.

4. Linen is expected to be used where strength, luster and absorbing power are desired. For instance, it is employed in toweling for its absorbing power; in decorative covering (table- cloths) both for luster and for stiffness.

5. For all forms of table linens and every purpose-demanding tensile strength and durability, flax is considered to be the best natural fiber.
