There is much historical evidence indicating that silk products were present in Egypt as far back as 1070 BC. But there is no questioning the fact that the humanity owes the knowledge of the silk manufacturing technique to the Chinese. It is rather curious that the people managed to keep the precious secret of silk worm cultivation and of the silk production procedure proper, out of their fibers, for as long as about 2000 years. The value of their knowledge and the wealth the Chinese nation possessed meaning silk worm, could hardly be overestimated. That's why, it was vigilantly protected indeed, as exporting worms across the borders of China was considered to be a serious crime. But eventually the secret of marvelous silk cloth leaked through Chinese immigrants to Korea and soon became the common property of almost all Asia. The half-legend half-history tells about the fact that a few cocoons of the silkworm were smuggled into Greece by a couple of Nestorian monks and it leads to further spreading of the precious knowledge from Greece to Turkey and Italy. This is the way sericulture (silk products manufacturing) became a developing industry in Europe. It is now widely known that silk is the result of the activity of an organism called the silkworm. They differentiate between the wild and the cultivated types of silkworms. The former produces coarse brownish fibers and the type of silk obtained form it is of the somewhat harder texture, in Japan it is referred to as wild silk. The wild silkworm inhabits China, Japan and India. The cultivated silkworm produces gray or yellow fibers that are tenderer. Making natural silk is very time and effort consuming as raising the cultivated type of the silkworm requires lots and lots of care. There is a great deal of sanitation issues that need to be kept in mind. The silkworm is a very delicate creature, and to get the desired result it is essential to provide it with the necessary living conditions, especially during the feeding period. After the feeding season of the silkworm is finished, this is when it starts to spin the cocoon. Their cocoons are formed with long threads of special gummy substance that in a while turns into more hardened fibers further used for making silk fabric. Silk fiber is the finest of all provided by nature, nevertheless, it possesses an incredible strength, especially when it is dry. Silk products are believed to be very wrinkle resistant as silk also possesses the quality of elasticity. The natural color of silk products is largely dependant upon the sort of food the silkworm received during the feeding season, the range of colors is from brownish, through yellow to creamy white. Due to the intrinsic quality of penetrability, characteristic of silk fiber, it is very susceptible of dyeing, unlike linen and cotton that do not give such a smooth and easy shade of color when dyed. Silk is not only pleasurable to wear, but also has a wonderful ability to imbibe perspiration and, nevertheless, to feel rather dry.
