Characteristics of silk fabric
1. The characteristic of silk fabric is that it is comfortable.Silk is composed of protein fibers, which have good biocompatibility with the human body, combined with a smooth surface, and are irritating to the human body. The coefficient of friction of all types of fibers is the lowest, only 7.4%.Therefore, when our delicate skin and silk want to meet, they will have a unique softness, according to the curve of the human body, so every inch of our skin is safe and considerate.
2. The characteristics of silk fabrics are two, moisture absorption and moisture dissipation.The amino (-CHNH), fibrin, amino (-NH2) and other hydrophilic groups enriched in silk are also easy to distribute water due to their porosity, so it can absorb moisture from the air or water supply and maintain a little water.At normal temperature, it can help the skin maintain a certain amount of moisture and not make the skin too dry. Summer clothes, sweat and inhibit the rapid release of heat in the body, make people feel very cool.It is this kind of performance that is more suitable for direct contact with human skin, so that we can use it as clothing, which is not only beautiful but also comfortable.
Silk is not only a better heat dissipation performance, but also good insulation.It is insulated by its porous structural fibers.In silk fibers, there are many very fine fibers.Therefore, the appearance of solid 38% silk is actually hollow, and there is a big gap in it to prevent the heat distribution of the air, so that the silk has good thermal insulation.
3. The characteristics of silk fabrics are three, heat-resistant, sound-absorbing and dust-proof.Silk fabrics have a large porosity and have good sound absorption. This is why, in addition to the production of clothing, they are also used for interior decoration such as silk carpets, tapestries, curtains, wallpaper, etc. The room is made of silk, which can not only reduce the dust of the house, but also keep it quiet. The room.Because silk has moisture absorption, dehumidification and moisture-proof properties, suction resistance and porosity, it can adjust the temperature, and it can also absorb harmful gases, dust, and microorganisms.
In addition, he is also a relatively heat-resistant fiber.It is heated to 100℃ and has only 5-8% fragility, which is 4 to 5 times the high level of rayon heat change.The combustion temperature of silk is 300-400℃, which is a kind of flame〜retardant fiber. It needs to be burned at a synthesis temperature of 200〜2600C, which is flammable and easy to melt.Therefore, as the raw material for interior decoration, silk fiber can not only play a sound insulation, dustproof, thermal effect and is characterized by flame retardant.
4. The characteristics of silk fabrics are four, anti-ultraviolet.The tryptophan and tyrosine in silk protein can absorb ultraviolet rays, and silk has good UV resistance.Ultraviolet radiation is very harmful to human skin.Of course, silk absorbs ultraviolet light, and it undergoes chemical changes. Therefore, under the sun's rays, silk can easily turn yellow.
