Three colors are the most taboo for mulberry silk
The most taboo color of silk quilts was black because the raw material of silk quilts was made of silkworm silk, and the color of silkworm silk was white or light yellow. Black was considered to be disrespectful and harmful to silk, and was often considered an unlucky color. It was generally avoided on silk products. Unable to find the other two taboo colors of mulberry silk, unable to give an accurate answer. The novel " Dream of Silk Fate " is equally exciting. Everyone is welcome to click and read it!
The three best colors of mulberry silk
The fine mulberry silk in the quilt could be divided into pearl white, bright white, light yellow, and yellow colors. However, considering the requirements for raw materials and quality, pearl white was a relatively better color. Because pearl white was the authentic color of good silk, it had extremely high requirements for raw materials. Only the silk of the whole cocoon could have such quality after the silk-making process. Moreover, the color of the silk of this color would change with the light, and the tenacity of the silk was good. Bright white might be the color of fluorescent brightening agents or excessive use of oxido-reducing agents, while yellowish and yellow might be inferior to pearl white in quality (due to factors such as raw cocoons or silk processing techniques). However, strictly speaking, there was no official definition of the three best colors of mulberry silk. The above was only a relative analysis from the information.

Mulberry silk appraisal agency
There were several institutions that could appraise mulberry silk. Among them, the China Science and Technology Testing Institute and the China Analysis Research Institute were professional third-party testing institutions. They had the qualifications of the CMA-CNAC, professional equipment, and talents. They could conduct the testing and identification of mulberry silk. Zhongke Testing provided a full range of testing and appraisal services at a reasonable cost, and issued professional test reports according to national and industry standards. The research and analysis center of the China Research Institute could also conduct mulberry silk testing. It had the CMA-testing qualification, complete testing equipment, and scientific and reliable data. These organizations could provide customers with accurate mulberry silk identification services.
Identification Method of 100% Mulberry Silk
Here are some ways to identify 100% mulberry silk: 1. Burning Method: Pull some mulberry silk from your clothes and burn it with a lighter. After burning, real mulberry silk would have the smell of burnt protein, similar to the smell of burning hair. The burning substance would be black-gray powder, which would be crushed with a pinch. If it smelled plastic, it would form a melted ball after burning, and it would be very hard to touch. If it was not crushed, it would be chemical fiber. 2. ** Appearance Observation **: - The surface of high-quality mulberry silk had a pearl-like luster. It was milky white and slightly yellow, and the silk threads were distributed in an orderly and neat manner. If it looked very "pale", lusterless, with more impurities and messy silk threads, it might be low-quality silk. - The real mulberry silk had light absorption, looking silky and soft, with a soft luster, while the imitation mulberry silk had obvious reflection, dazzling luster, light texture, and rough perception. 3. ** Feeling Judgement **: - Real mulberry silk was soft and elastic. It had good elasticity and was easy to stick to the hand. The longer the thread was pulled, the better the quality. The stretch and elasticity of inferior silk would be much worse. - Mulberry silk has good moisture absorption, is air and heat preservation, has a certain degree of elasticity, feels warm and moist, and has good drapability. It will feel cool and hold hands when touched, and slight wrinkles will appear when grabbed by hands. Rayon and chemical fiber products have a blocking feeling when touched, and will generate static electricity when touched, and have a sense of absorption to the skin. 4. ** Look at the washing label **: The washing label should strictly indicate the safety technology category, implementation standards, and composition of 100% mulberry silk. If it was a bunch of foreign languages, especially the English words "HAND FILM LIKEN SILM", or if it only wrote real silk, mulberry silk, and vinegar fiber without specific proportions, it was basically fake. Some clothes that contained 5% mulberry silk were publicized as mulberry silk products that were passed off as fish eyes. 5. ** Price considerations **: High-quality 100% mulberry silk will not be too cheap. If the price is too low, it may be tussah silk (wild silkworm cocoon, yellow silk color, brittle material, hard texture, easy to break), mulberry silk short silk (inferior silkworm cocoon, treated with chemicals), or cloth with very low mulberry silk content. 6. ** Wetting and breaking method **: Take a few threads from the fabric, wet the threads with water and break them by hand. If it was easily torn and the fracture was too flat, it was fake mulberry silk. After wetting, its toughness increased, and there were different lengths of hair at the fracture, it was genuine mulberry silk. 7. ** Judgment of fire **: Genuine mulberry silk burns slowly and will shrink into a ball. After burning, it will emit a burning smell. There is no open fire. After leaving the fire, it will form dark brown particles, which will turn into ashes when twisted by hand. Imitated mulberry silk fabric will have flames when burned. After leaving the fire, the flames will continue to burn. After the fire is extinguished, spherical hard particles will appear at the edge of the fabric, which will be hard when twisted by hand. 8. Drug identification: Ask the merchant for a small amount of the same cloth as the product you purchased, or take off some silk thread from the edge of the product, soak the cloth in a small cup of 84 disinfectant for about 20 minutes and stir it well. Real mulberry silk was made of animal protein, which would gradually melt. When it melted, irregular small bubbles would appear around the cloth, and finally it would all melt. Fake mulberry silk would not melt, let alone obvious bubbles. 9. ** Shrinkage or not **: Genuine mulberry silk is generally processed by the manufacturer in advance. The fabric is shrunk to the best state of the fiber before it is put on the market, so there is generally no shrinking phenomenon. Ordinary mulberry silk generally does not have this process. It may shrink seriously during washing. 10. ** Wrinkle Free **: The seller randomly grabbed a handful of real mulberry silk clothes during the live broadcast and rubbed them between his hands. When rubbing, a silk sound could be heard. No matter how long he rubbed, after releasing his hand, the fabric immediately stretched out. No wrinkles could be seen, and the elasticity was strong. It felt delicate and smooth. 11. ** Electrostatic prickling sensation **: If static electricity occurs when you try it on, or if you feel itchy and stuffy on your skin, it's likely to be fake mulberry silk. Real mulberry silk is not only anti-static, but also has good breathability and anti-itch function. It's also easy to dissolve in the basic solution of NaClO.

Is human silk fragrant cloud yarn mulberry silk?
Fragrant cloud yarn usually used mulberry silk as the base material. However, in today's diverse society, there were also situations where non-mulberry silk (including artificial silk, or artificial silk) was used to dye and finish fragrant cloud yarn. Therefore, artificial silk fragrant cloud yarn was not mulberry silk. The novel "Dream of Silk Fate" is equally exciting. Everyone is welcome to click and read it!
Pure silk, mulberry silk, Luo Xiang cloud yarn
Silk was a large type of fiber formed by silk secreted by silkworms, including mulberry silk, caster silkworm silk, cassava silk, and so on. Mulberry silk was a type of real silk, specifically referring to the fibers formed by the mucus secreted by silkworms, which was also the silk extracted from cocoons made of mulberry silk. Hualuo Fragrant Cloud Gauze was a special kind of Fragrant Cloud Gauze. Fragrant Cloud Gauze used mulberry silk as the base and was dyed with plant dye. Hualuo Fragrant Cloud Gauze was the only silk textile that was dyed with pure plant dye and was known as "soft gold". It was very waterproof, easy to wash and dry, not easy to fade, durable and durable. It was usually dark, more resistant to dirt, good softness, excellent elasticity, and delicate feel. The front side of the fabric was black or brown, and the back side was light-colored. It was sweat-resistant, sun-resistant, wrinkle-resistant, cool, and easy to wash. It was very suitable for hot and humid weather. There were many processes in the production of Fragrant Cloud Yarn. There were more than ten processes. The dyeing process took half a month. Moreover, modern technology could not make the feel and different patterns of Fragrant Cloud Yarn. All the processes had to be completed by hand. The novel " Dream of Silk Fate " is equally exciting.

Quality Inspection Report of Mulberry Silk
The quality inspection report of mulberry silk needed to test both the filling (silk) and the fabric. The precautions for the filling included the type, length, content, impurity content, and environmental indicators (such as the pH value) of the silk. The type of silk should be mulberry silk, and the length should be long silk cotton or medium-long silk cotton. The content must meet the requirements of high-grade and first-grade products, and the impurity rate and oil content should also be limited accordingly. The testing items for the fabric included appearance quality, composition, formalin content, PH value, nitrogen, odor, oil content, moisture regain, weight, compression resilience, contraction rate, and color firmness. For specific testing standards, you can refer to the relevant standards such as "GB/T2910-2009" and "GB/T32016-2015". However, the given information did not provide specific quality inspection report results, so it was impossible to give a specific answer.
Mulberry Silk Quality Inspection Report
Mulberry silk quality inspection report was a report on the quality of mulberry silk products. The quality inspection report mainly focused on two aspects: the filling (silk) and the fabric. In terms of fillings, one needed to pay attention to the type, length, content, impurity content, and environmental indicators of silk (such as the PH value and the content of formalin). The filling of the mulberry silk quilt should be mulberry silk, and the silk content of high-grade and first-grade silk quilts must reach 100% and be long silk cotton or medium-long silk cotton. The silk content of qualified silk quilts should reach more than 50%. In terms of fabric, one needed to pay attention to the composition and content, environmental indicators (such as the PH value and the content of Formalide), and the content of aromatic aromatic amine that could be decomposed after dyeing. The quality inspection report could be tested by the testing institution. The testing period was usually 3-10 working days. The testing fee needed to be quoted according to the specific project and the complexity of the experiment. The testing range included silk quilts, mulberry silk, silk nightdresses, silk protein, silk rope, silkworm silk, tussah silk, silk fabrics, silk fibers, and silk fabrics. For testing standards, you can refer to the following standards: "Silk Quilt","Determination of Silk Acid","Silk Performance and Test Terminology","Silk, synthetic fiber screen", and "Silk, synthetic fiber screen".
The simplest way to detect mulberry silk
The easiest way to test mulberry silk was to observe its appearance and feel. The appearance of mulberry silk should be shiny, soft to the touch, clear silk lines, regular patterns, no obvious impurities and defects. In addition, he could use the fire method to test it. A small section of silk was lit with a lighter. When the real silk burned, it would emit white smoke. It was flame resistant and would automatically extinguish after leaving the fire source. The ash was grayish black and very brittle. It would turn into powder after pinching it. It could also be distinguished by touching it. Mulberry silk felt smoother and easier to stick to the hand, while tussah silk felt a little astringent and was not easy to stick to the hand. Finally, he could use the static electricity method to pull out some of the silk quilt, fold it up and rub it quickly. If the silk was a poor conductor of electricity, it was not easy to generate static electricity, so it would not attract small paper scraps.
What's the difference between a mulberry silk quilt and a silk quilt
The difference between mulberry silk quilts and silk quilts was mainly reflected in the following aspects: 1. ** Source of silk **: The silk of the mulberry silk quilt comes from silkworms, which are mostly domesticated and generally produced in southern areas such as Jiangsu and Zhejiang. The source of silk for the silk quilt is relatively more extensive, including the silk produced by wild silkworms. 2. ** In terms of quality, the quality of mulberry silk quilts was relatively good. The length of mulberry silk fibers could reach more than 1000 meters, while the length of silk quilts made of tussah silk generally did not exceed 80 centimeters. In terms of fiber length, mulberry silk quilts had an advantage. 3. ** Color and luster **: Mulberry silk presents a natural white color, and there is no need for chemical rinsing when making mulberry silk quilts. When making silk quilts with wild silk, it is often necessary to add "fluorescent brightening agent" and other methods to fade and chemical rinsing, so that its color and feel are closer to mulberry silk quilts. 4. ** Price **: Due to the short life cycle of silkworms, mulberry silk is relatively more precious and the price is higher. Wild silkworms can be artificially raised, so the production cost of silk quilts is relatively low and the price is relatively low. 5. "Usage inclination": Mulberry silk is fine and soft, and the fabric is as thin as silkworm wings and as light as yarn. It is more suitable for light and thin clothing. Tussah silk is thick, fluffy, stiff, and has many pores in the internal structure of the fiber. It is produced in the northern cold zone. It has good warmth and elasticity. It is the preferred raw material for making home textile products such as silk quilts and silk blankets. 6. ** Appearance color **: The silkworm cocoon is white, and the mulberry silk is quite white. The tussah cocoon is slightly yellow, and the tussah silk will turn yellow no matter how it is processed. 7. ** Reflected on the quilt label: If the quilt composition table wrote "Fillers: 100% silk", the quilt was mostly made of oak silk instead of mulberry silk.
