Introduction Of Silk Fabric And Its Washing And Maintenance Methods

　　 Silk fabric Soft and smooth texture, soft and light feel, colorful patterns, cool and comfortable to wear. Its main advantages include:

First, comfort. Silk is composed of protein fiber, which has excellent biocompatibility with human body. In addition, its surface is smooth, and its friction stimulation coefficient to human body is the lowest among all kinds of fibers, only 7.4%. Therefore, when our delicate skin meets the smooth and delicate silk, it takes care of every inch of our skin thoughtfully and safely with its unique soft texture and the curve of the human body.

Second, good moisture absorption and desorption. Silk protein fiber is rich in many hydrophilic groups such as amino group (- CHNH), amino group (- NH2), and because of its porosity, it is easy for water molecules to diffuse, so it can absorb or emit water in the air, and maintain a certain amount of water. Under normal temperature, it can help the skin to retain a certain amount of moisture, so as not to make the skin too dry; Wearing it in summer can quickly dissipate sweat and heat from human body, making people feel extremely cool. It is precisely because of this performance that silk fabrics are more suitable for direct contact with human skin. Therefore, people regard silk clothing as one of the necessary summer clothes. Silk not only has good heat dissipation performance, but also has good warmth retention. Its thermal insulation is proud of its porous fiber structure. There are many tiny fibers in a silk fiber, and these tiny fibers are composed of even smaller fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow, and there is a large amount of air in these gaps, which prevents the heat emission and makes the silk have good warmth retention.

Third, sound absorption, dust absorption and heat resistance. Silk fabrics have high porosity, so they have good sound absorption and air absorption. Therefore, in addition to making clothes, they can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall coverings, etc. Decorating a room with silk ornaments can not only make the room spotless, but also keep the room quiet. As silk has moisture absorption, moisture release, moisture retention, air absorption and porosity, it can also adjust indoor temperature and humidity, and absorb harmful gases, dust and microorganisms. In addition, the heat denaturation of silk fiber is small and relatively heat-resistant. When it is heated to 100 ℃, it is only about 5-8% brittle, and the thermal variability of most synthetic fibers is 4-5 times greater than that of silk. The combustion temperature of silk is 300~400 ℃, which is a non combustible fiber, while the combustion temperature of synthetic fiber is 200~2600 ℃, which is flammable and fusible. Therefore, using silk fiber as the raw material for interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play the role of flame retardant. Fourth, UV resistance. Tryptophan and tyrosine in silk protein can absorb ultraviolet light, so silk has a good anti ultraviolet function. Ultraviolet rays are very harmful to human skin. Of course, after absorbing ultraviolet rays, the silk will undergo chemical changes, which will make the silk fabric yellow under the sunlight.

Washing method

Water washing: silk clothing is made of protein delicate health care fiber, which should not be rubbed with rough articles or washed with a washing machine. The clothing should be immersed in cold and clean water for 5-10 minutes, and the special silk detergent should be used to synthesize low foam detergent or neutral soap to gently rub, and the colored silk clothing can be repeatedly rinsed in clean water.

Air drying: silk clothing should not be exposed to the sun after washing, nor should it be heated by a dryer. Generally, it should be placed in a cool and ventilated place to dry. Because the ultraviolet rays in the sun easily make silk fabrics yellowing, fading and aging. Therefore, it is not advisable to wring the water off the silk clothes after washing. They should be gently shaken off, spread out to air in the opposite direction, and then iron or shake flat after drying to 70% dry.

Ironing: the wrinkle resistance of silk clothing is slightly worse than that of chemical fiber, so it is said that "wrinkle free is not real silk". If the clothes are wrinkled after washing, they need ironing to be crisp, elegant and beautiful. When ironing, dry the clothes to 70% dry, spray water evenly, and wait 3-5 minutes before ironing. The ironing temperature should be controlled below 150 ℃. The iron should not be pressed directly on the silk surface to avoid aurora.

Preservation: To preserve silk clothing, thin underwear, shirts, pants, skirts, pajamas, etc. should be washed and ironed before collection. For autumn and winter when it is inconvenient to remove and clean clothing The coat surface and cheongsam should be cleaned by dry cleaning and ironed until they are smooth to prevent mildew and moth. After ironing, it can also kill bacteria and insects. At the same time, the boxes and cabinets for storing clothes should be kept clean and sealed as far as possible to prevent dust pollution.

Maintenance method

1. When purchasing silk fabrics, you should pay attention to purchasing 2-4cm larger than your original size, so that you can wear them comfortably and not easily damage the silk protein fiber.

2. Silk fabrics should be ironed at medium temperature (130 ℃ - 140 ℃).

3. Silk fabrics should be dried in the shade and cannot be dried in the sun or under fluorescent lamps.

4. It is better to store silk clothes on the wall and keep them dry. Insect repellents must be wrapped in cloth and do not directly touch clothes.

5. Silk fabric is highly hygroscopic, so it is better to hang clothes with hangers and keep ventilation when not wearing them; If the clothes are not very dirty, do not wash them. Hang the worn clothes in a ventilated place until the sweat evaporates; If the clothes are not very dirty, they can be rinsed directly with clean water without any detergent. It is recommended not to wear one clothes for a long time, and replacing it can reduce the number of times that silk clothes get into the water.

6. Silk fabrics wrinkle easily when worn. You can find a small spray bottle, which can be filled with water and sprayed slightly on the wrinkled area.
