Nowadays, many home textile companies are selling silk quilt products and slogan "Silk is warm in winter and cool in summer". As we all know, silk is cold, so it is debatable whether this statement is correct or not.
Silk is a porous fiber that can inhale, deflate and contain gas. Silk quilt, that is, a filler containing 50% or more of mulberry silk and/or tussah silk. Silk is divided into two types: pure silk quilt and mixed silk. Among them, the silk content of 100% is called pure silk quilt; the silk content of 50% or more is called mixed silk quilt. On June 19, 2009, the National Standardization Committee issued the national standard GB/T24252-2009 "Silk quilt", which was implemented on February 1, 2010. The implementation of the standard will change the situation in which the silk is inconsistent with the industry, and it will also help consumers to buy genuine silk quilt products.
From the fiber structure, the silk fiber is composed of about 70% of fibroin and 25% of sericin. When silk fibroin is composed of silk core, the gap of 35% silk volume is left, and the sericin covering the outer layer also contains hydrophilic side chain amino acid, so that the silk has good moisture absorption performance. It can reduce the thermal conductivity when it is cold, and the warmth is better than the skin and cotton. When it is hot, it can discharge excess heat, so that the internal temperature is maintained in a comfortable state. As a result, many companies claim that silk is “cool in winter and cool in summerâ€. For the handmade silk quilt, that is: the hand-made "long fiber" silk quilt, it has a good winter warm and cool summer effect. However, for the "mechanical silk quilt" that exists in large numbers at present, such claims have certain irrationality.
First of all, silk is used as a silk product that has risen in recent years. Its production method has also changed from a traditional handicraft workshop to a specialized and large-scale production combining mechanical and artificial, that is, "mechanical silk quilt" - through machinery and equipment, A large number of silkworm cocoons can be laid flat. Almost all of the fibers of this type of silk are disturbed and broken, or some fillers are dropped silk, belonging to "short fibers". Since almost all of the processing is controlled by the machine machinery and the softness of the fiber itself, the mechanism silk is easily formed into a mass by the inner silk short fibers. At the same time, in the use, there will also be faults, agglomeration and thinning of the internal fibers, which seriously affects the gas permeability, and the articles with poor gas permeability are prone to sputum when sweating. Although the water absorption of silk is 1.5 times that of cotton, when the human sweat adheres to the silk quilt and cannot be discharged in time, the internal humidity is increased. Thus, due to the high external temperature, the sweat is exothermic, and the summer will appear moist and stuffy; In winter, the outside temperature is low, the sweat is endothermic, and the micro-air conditioning phenomenon occurs. The human body temperature drops and the cold feels. Secondly, when the mechanism silk is used for a period of time, the elasticity is deteriorated, and the fibers are easily pinned. After a long time, the knot will be knotted. Unite block, the permeability is reduced, as in the previous situation, it also does not achieve the effect of "warm winter and cool summer", and also greatly reduces the comfort.
Natural silk quilts also have their own unique functions: the special "silk gum" contained in silk: sericin ingredient, which has anti-allergic and skin-friendly effects. Long-term use of high-quality silk quilts can promote human health. Such as: light weight, soft; promote sleep; have a certain auxiliary effect on the prevention of rheumatoid arthritis and skin diseases.
The perpetual model of the silk industry can reproduce soil and reduce carbon emissions. With the rapid development of technology, especially since the invention of chemical fibers in the last century, the choice of bedding has become wider and wider. Nowadays, there are many alternative products for silk quilts and duvets. Among them, the fluff fluff and the series of products are emerging, and they are favored by the unique properties of light, thin, soft, green and environmental protection.
