Do you know what the main ingredients of silk quilt are? Many people want to buy a comfortable silk quilt. Do you know its composition, advantages and disadvantages? Below, I have carefully arranged the knowledge and information related to the composition of silk quilt for everyone, hoping to help you distinguish the quality of silk quilt.
Composition of silk quilt 1 1. What is the main component of silk?
Silk is a kind of natural fiber, which is light, soft and delicate. Known as "the second skin of human body", it is called "the queen of fiber" by the industry. Its main component is pure natural animal protein fiber, and its structure is the closest to human skin, 87% of which is the same. Contains a variety of essential amino acids, and has the effects of preventing wind, removing dampness, calming the nerves, nourishing and balancing human skin. Silk is smooth, breathable, soft, moisture-absorbing, non-itchy and antistatic, and it is a superior material for making close-fitting clothes. Silk quilt with silk as lining has unique qualities and advantages such as close-fitting warmth, fluffy softness, ventilation and health care. In ancient times, the quilts of dignitaries, royalty and relatives used silk quilts. So the silk quilt is the most comfortable quilt to cover.
Secondly, the main chemical components of silk are introduced.
The chemical composition of silkworm cocoons raised by mulberry leaves is: moisture 1.40%, ash 1. 14%, protein 97.34%, ether soluble extract 0.26% and fiber 0.39%. Cocoons are mainly made of fibrous protein FIROIN wrapped with another sericin from protein, and also contain a small amount of oil, pigment and inorganic substances. In raw silk, silk fibroin accounts for about 70% and sericin accounts for about 22%. Silk fibroin is a kind of keratin, and its amino acids are glycine and alanine, which account for about 80% of the total nitrogen. 105g fibroin contains amino acids in the following order (the number after the substance is the number of moles): glycine 578, alanine 38 1, valine 29, leucine 7, isoleucine 9, serine 157, threonine 12, tyrosine 67, phenylalanine 8 and proline.
Sericin is also keratin, and its amino acids are generally similar to silk fibroin, but glycine, alanine and tyrosine are slightly different. Serine, glutamic acid and aspartic acid are more. Cocoon also contains 50mg% free hydroxy acid (calculated by glycine). Cocoon contains oily waxy substances, which are composed of primary alcohols (C28-C32), solid fatty acids (C26-C32), paraffin wax (C25-C3 1) and liquid fatty acids. It also contains sitosterol (glucoside) and lupeol. There are various carotene derivatives in yellow cocoon, which are also cocoon colors such as yellow orange, pink and brown gray.
Composition of silk quilt II. Advantages of silk quilt
1, promoting sleep. Sericin contains amino acids that can emit "sleep factors", which can make people's nerves in a stable state. Covering with silk quilt can improve sleep, enhance human vitality and delay aging.
2, good cold resistance, constant temperature. Silk quilt has the reputation of "queen of fiber", which contains the highest "silk gap" among fibers, and can reduce the thermal conductivity when it is cold. Good mulberry silk has good warmth retention, good air permeability and lightness.
3. It has anti-mite, anti-bacterial, anti-allergic and skin-friendly properties. Sericin not only makes people's skin delicate and shiny, but also has the ability to prevent mites and molds from breeding, which is more conducive to allergic constitution.
4. Prevent rheumatism, arthritis and skin diseases. Natural silk can absorb moisture in the air, remove moisture and keep the quilt dry and comfortable. And can prevent rheumatism, arthritis and dermatosis.
5, asthma, it is difficult to die in winter and autumn; Most asthma patients have allergies or rhinitis. We just talked about allergies. Rhinitis has a lot to do with breathing. Silk is the cleanest natural fiber, and there won't be much dust in the quilt, which won't cause allergic rhinitis.
Second, the shortcomings of silk quilt
1, easy to generate static electricity. Silk products, in the case of dry weather and high temperature, are prone to generate a lot of static electricity when rubbed, which stimulates the surface nerves.
2, easy to breed bacteria. Silk products contain a lot of protein, which is easy to stay in humid air and breeds a lot of bacteria. The harm to human body is obvious, especially at night when human immunity is weakest. Silk products with poor air permeability gain a lot of weight, which improves the warmth retention effect, but the air permeability decreases. Mainly because silk is a slender silk thread, which is relatively soft and easy to kink and stick together, affecting air permeability. Products with poor air permeability are easy to sweat and catch cold when pushing the quilt.
