gone in silk and secrets

The Silk Road was active at least from the 2nd century B.C. to the 15th century A.D. It lasted about 1700 years from the 2nd century B.C. to the 15th century A.D. However, according to archaeological evidence, the trade across the Central Asian deserts managed by the ancient steppe society began at least 5,000 - 6,000 years ago. If you count from this starting time, it has been longer. However, it was now clear that the Silk Road trade had lasted for about 1700 years. The novel "Dream of Silk Fate" is equally exciting.

Silk satin was a type of fabric, usually made of various fibers. It had a smooth, shiny appearance and a soft feel. It was often used to make high-end clothing, bedding, and so on. Mulberry silk was a type of natural fiber. It was a type of silk produced by silkworms. The mulberry silk fiber was slender, white, and had good elasticity, toughness, and warmth. It felt soft and silky, and had a strong luster. The main difference between the two was that silk satin was a finished fabric, while mulberry silk was the raw material for making fabrics. Silk satin could be made from a variety of fibers, including but not limited to mulberry silk, and mulberry silk could be used to make a variety of fabrics, including silk satin fabrics.

Silk was not 100% mulberry silk. Spun silk was a product of silk spinning. It was a product obtained from the spinning process of processing defective cocoons and waste silk produced in silkworm rearing, silk making, and silk weaving into yarn. Mulberry silk was a continuous long fiber formed by the secretion of silk liquid when mature silkworms spun cocoons. The novel " Dream of Silk Fate " is equally exciting.

The specific amount of the joining fee for Silk Love Silk Doll varied according to the region and the size of the store. According to different documents, the joining fee was about 50,000 yuan, and some documents mentioned that the joining fee was between 200,000 yuan and 500,000 yuan. In addition, some documents mentioned that the joining fee was between 10,000 to 50,000 yuan. Considering the specific situation of the local and individual, the amount of investment would vary. Therefore, the specific joining fee for Silk Lover Doll needed to be considered according to the actual situation.

Fu Anna had 100% mulberry silk quilt products. Their prices varied due to specifications, promotions, and other factors. For example, there was a Fuanna 100% mulberry silk duvet core two-in-one duvet core for four seasons (9.5 jin, 230*229cm). The original price was 2999 yuan, and the price after promotion was 1499 yuan. There were also Fuanna Fandy 100% mulberry silk duvet core two-in-one duvet (11.4 jin, 230*229cm) and other products. When buying a Fuanna 100% silk quilt, one could tell whether it was real or fake through the price, label, zipper, appearance, breathability, combustion test, and other methods. In terms of price, the price of 100% pure mulberry silk quilt was generally higher, usually starting from 3,000 to 4,000 yuan. The label should clearly write the product name and composition; There may be a small amount of mulberry silk exposed in the middle of the zipper; Real mulberry silk is generally silver-white and glossy, while fake may be white or other colors without luster; In terms of breathability, real mulberry silk quilt has good breathability, which can be tested by covering the mouth and nose and breathing through the quilt; He could also use a lighter to ignite the things in the quilt. After the real mulberry silk burned, it would turn into black particles. The novel "Dream of Silk Fate" is equally exciting. Everyone is welcome to click and read it!

No, it wasn't. The silk of the Dual-palace Cocoon was the silk produced by the cocoons formed by two silkworm babies. It was usually mulberry silk. The silk threads were neat and clear, with an average length of up to two meters. The thickness of the silk was more than 95%. It was not easy to harden, and its color was white with yellow. It felt delicate and smooth, and it had a faint smell of animal fiber. Tussah silk was the silk produced by tussah, and the two had different characteristics.

The main differences between artificial silk and natural silk were as follows: ** 1. Strength and mechanical properties ** 1. ** Stretching Strength ** - Artificial silk had a higher tensile strength than natural silk. For example, the tensile strength of artificial silk fiber reached 2.0 GPa, while the tensile strength of natural silk (such as de-glued natural silk) was about 610 + 84 Pa. The tensile strength of artificial silk was about two times higher than that of natural silk. 2. ** Young's Modality ** - Artificial silk had a higher average Young's elasticity of 43GPa, which was much higher than all known natural microfibers (<20GPa), indicating that artificial silk had better resistance to elastic distortion than natural silk. ** 2. Production process ** 1. ** Material processing ** - Natural silk was a continuous long fiber formed by the silk liquid secreted by mature silkworms when they spun cocoons. It was a natural animal fiber. - Artificial silk was obtained by special treatment of ordinary silk. For example, inspired by the artificial spinning of spider egg silk, the sticky outer layer of ordinary silk was removed by a special chemical bath (such as the use of sulfuric acid and sulfuric acid to help dissolve the outer layer of silk), and it was prepared by combining metal ions to assist in strengthening. 2. ** Stabilizing treatment ** - In the process of making artificial silk, because the main component of silk was protein, in order to prevent its degeneration, a mild environment was needed. At a relatively low temperature, chemicals such as papain, Na2CO3, and Na2S2O4 were used to dissolve the outer sticky layer of the silk, ensuring a high rate of silk de-sizing while maintaining a relatively stable protein, thus laying the foundation for good mechanical properties of the artificial silk. Then, metal ions were used to assist in the enhancement of artificial spinning in the microtube. The production of natural silk mainly relied on the natural physiological process of silkworms and did not require these special chemical treatments to ensure stability. ** 3. Quality and production ** 1. ** Quality stability ** - Due to different silkworm eggs, different feeding methods, and other factors, the quality of natural silk was not stable, and there were differences in quality. If artificial silk could be mass-produced, the production process would be relatively controllable and the quality stability might be higher. 2. ** Production ** - The production of natural silk depended on the cultivation of silkworms. Silkworm cultivation was laborious and time-consuming. In modern times, its quality and output were increasingly unable to meet the demand. If artificial silk achieved a breakthrough in mass production technology, it was expected to increase production to meet more demand. ** 4. In terms of application prospects ** 1. ** Potential in traditional application fields ** - In the traditional silk textile field, natural silk had always been the main raw material, such as making silk quilts and silk skirts. Due to its outstanding strength and stretching properties, artificial silk could replace natural silk in these traditional fields in the future or be used to make silk products with higher quality requirements. 2. ** New applications ** - Natural silk could be used to make sutures and surgical mesh materials in the field of biomedicine. Due to its higher strength and other properties, artificial silk was expected to be used to produce lighter armor and bulletproof vests in the future. This was an application field that natural silk was difficult to satisfy. The novel "Dream of Silk Fate" is equally exciting. Everyone is welcome to click and read it!
