Quercus serrata has some advantages that mulberry silk does not have, such as low prices, good permeability, but not suitable for silk quilt for a number of reasons, such as easy to hairy, puckering, in contact with water, there will be a "water stain" formation, with its silk quilt, it is easy to be yellowed for a long time, that is, not long after the use of the quilt is easy to deformation of the inner tube. In addition, there are the following differences: Difference one, cocoon color is different Mulberry silkworms to mulberry leaves for food, is a domestic silkworm. The serpentine silkworm eats the leaves of the quercus tree, and the feeding method is closer to the wild silkworm; the mulberry silkworm belongs to the "Lepidoptera" of the "Silkworm Moth Family", while the serpentine silkworm belongs to the "Lepidoptera" of the "Large Silkworm Moth Family", and the serpentine silkworm belongs to the "Lepidoptera" of the "large silkworm moth family. Mulberry silkworms belong to the "Lepidoptera" family of "Silkworm Moths", while Quercus serrata belongs to the "Lepidoptera" family of "Daphniaceae", which are technically two kinds of insects. Mulberry cocoons are mostly crystal clear white. Quercus cocoons are mostly dark brown and grayish green. Difference two, different processing technology Mulberry silk (cocoon) presents natural white, so in the production of silk quilt, completely without any chemical bleaching process. Therefore, a bed of real, truly natural silk quilt, must be the cocoon of mulberry silkworms as raw materials, but also the only raw material. Quercus serrata silk (cocoon) is different, if not processed directly into a quilt, whether it is the color or feel, consumers are usually difficult to accept. Merchants in order to feel as well as the color closer to the "mulberry silk", often through the addition of "fluorescent whitening agent" and other tactics for fading and chemical bleaching, and fluorescent agents have been proved by modern science on the human body has a carcinogenic effect, a health hazard. As long as the bedding, safety, health is certainly the primary factor, and thus in the case of the business clearly informed, the vast majority of customers would rather spend more money, buy mulberry silk quilt, a little more peace of mind and a sense of security. Difference three, silk color and lustre is different Mulberry silk is natural milky white, if you look carefully, will be slightly found with a light green or yellow, the overall luster is bright. The bleached silk, also white, but a miserable white, like A4 paper, white "very regular", white "very chapter and verse", white but lifeless. Let's take another example, I believe you can quickly distinguish the difference between "the color of gold" and "yellow", because the color system of gold is very complex, it is impossible to use any one simple color to express. Without artificial chemical treatment of mulberry silk floss, as if gold and diamond-like have many refractive surface, bright but not blinding. Difference four, different fiber diameter "fiber diameter" is different, in layman's terms, is the thickness of the fibers are different, as a quilt, in addition to warmth, softness and breathability, the weight is also one of the assessment index, the same quality, the same effect, of course, is the lighter the better, otherwise with the cover of the thick cotton blanket is no different, the pressure of the people are not able to breathe. Bo Lei Xiu found that the same volume of mulberry silk, the weight to be less than quassia silk, which is its silk cotton fiber is different from the decision. Mulberry silk fiber diameter of 8 microns, while the diameter of sericea silk reaches more than 70 microns, nearly 9 times the mulberry silk. Difference five, fiber length and toughness of different fiber toughness and length, determines the fiber later processing molding quilt way. Currently there are two kinds of handmade and mechanism. Mulberry silk belongs to long fibers, like elastic rubber bands, with superior elasticity and toughness, 10 times the extension is not constant, a small cocoon silk, even if it is pulled to the area of the whole bed quilt, there will be no folding breaks, so it is more suitable for hand-pulled silk quilt. Quercus silk fiber is shorter, less elastic toughness, so the "mechanism of silk quilt" more Quercus silk. Difference six, touch feel different If the core is not covered for a long time, the block, a group set into a hard block of the quilt is certainly not heat preservation and comfort, and mulberry silk can be a good solution to this problem, its high quality ultrafine fibers, determines the nature of its smooth, regular fiber distribution, touch with your hands obviously feel silky smooth, no hard blocks. While Quercus silk feels dry and rough to the touch, and the fiber distribution is uneven. By the State Administration of Quality Supervision of the latest release of the silk quilt industry standard (GBT24242-2009), also feel and hard lumps, etc. made clear instructions, so the mulberry silk quilt, more delicate, durable, and less likely to be lumps. In summary, although Quercus serrata silk is not lost as a high-level textile raw materials, but for processing into silk quilt, or less than mulberry silk.
