Silk Health Benefits
Chinese scientific study has found that silk has good health benefits. Silk is protein fibre. Silk protein is one of the only few pure proteins. It contains 18 amino acids which are similar to those in human skin. Studies have shown that silk can help to maintain the metabolism on the surface membrane of the skin to keep the skin moist and smooth.
In addition, it has subsidiary cure for certain dermatitis. Silk fabric can also protect against the harm caused by ultraviolet radiation from the sun.
Silk is a kind of ecological non-pollutant natural fibre. It has unique features that are irreplacable by other fibres and artificial fibres. It is relatively resistant to ageing. Yarn-dyed silk fabric of different gorgeous clours has been made to all kinds of luxury garments, interior adornments, arts and crafts works, and tour souvenirs. No wonder silk has been acclaimed by customers as "Source of Beauty". So, what are the benefits of wearing garments made from silk fabric? Following are the four aspects to explain the benefits of wearing silk garments.
1 Silk is comfortable to wear. Silk fabric is composed of natural fabres. It is biologically consistent with human's body. Additionally, because of its smooth serface, its frictional coefficient is only 7.4% which is the lowest among other fibres. Therefore, when our tender skin meets with smooth and gentle silk, silk will keep close to your body's curve by its special soft quality to considerately look after every inch of your skin.
2 Silk is hygroscopic and readily absorbs moisture. Silk protein fibre is abundant in amidocyanogen (-CHNH, -NH2) hydrophile gene groups. Also because it is porous, it facilitates the pervasion of moisture. So, silk can absorb or pervade moisture from the air, and keep the moisture in it. At normal temperature, silk can keep the skin moisture. In summer time, wearing silk garments can immediately emit the perspiration and heat from your body to keep you cool. Just because of this special feature, it is more suitable for silk to directly contact human's skin. So, people are used to keep silk as one of the essential summer clothes in their wardrobe.
Silk not only has good thermal dissipation to keep you cool, but also to keep you warm. This benefit thanks to its porous porous structure. In one silk fibre, there are many very fine fibres, and these fine fibres are also composed of even finer fibres. So, 38% of one solid looking silk thread is hollow. There are a large amount of air among these hollow spaces. These air prevent the loss of the warmth from your body.
3 Silk can absorb sound, dirt, and is heat-resistant. Silk fabric has relatively higher interspacing ratio, so it has very good soud and inspiration absorbing capacity. Beside garments, silk can also be used for interior decoration, such as silk carpet, tapestry, curtains, etc. Using silk to decorate room not only making the room tidy and clean, but also to make the room quieter. Because of its ability of moisture absorption, moisture discharge, inspiration and porosity, silk can adjust humidity and temprature of the room, and absorb the harmful gas, dirt, and animalcule. In addition, silk fibre has little heat denaturation, so it is relatively more heat-resistant. When silk is heated to 100℃, only about 5~8% of it became crumblized. But other synthetic fibre has 4~5 times more heat denaturation than silk. Silk's burning temperature is between 300~400℃, it belongs to flame retardant fibre. Synthetic fibre's burning temperature is between 200~260℃ which is inflammable and solvent. Therefore, using silk fabric as interior decoration material can not only absorb sound, dirt, keep warm, but also can retard flame.
4 Silk is ultraviolet radiation resistant. The tryptophan and tyrosine in silk protein can absorb ultraviolet radiation. So, silk has good ultraviolet radiation resistant function. Ultraviolet radiation is very harmful to human's skin. Of course, after absorbing the ultraviolet radiation, it will cause chemical change in itself, so that silk fabric will become yellowish in the strong sunshine.
Silk has been called “Empress of Fibre”. She has been favoured by people all over the world for her special charm.
