Are you worried about whether the boski fabric you buy is genuine "boski ki pehchan"? Are you worried that the boski fabric you bought at a high price is not made of mulberry silk, but made of man-made fiber? If your answer is yes, then the following content is worth to read.
The quality and price of boski fabrics vary greatly on the market. If you want to buy pure boski fabric, you need to pay attention to the following guide:
7 Tips to Identity Genuine Boski
Genuine original boski fabric is made from 100% mulberry silk, not man-made or blended fibers. You can identify real silk and rayon by touching, listening, observing luster, soaking in boiling water, water test, comparing creases and lighting with fire.
Tips 1:Touch with your hands.
Silk fabric is soft, delicate, elastic, and sometimes feels a bit "sticky". Rayon fabrics feel stiff or unusually slippery.
Tips 2:Listen to the sound with your ears
Silk fabrics will make a "rustling" sound when rubbed, which is called "Si Ming" or "Silk Ming". Rayon fabrics are silent.
Tips 3:Observe the gloss
The luster of silk fabric is elegant and bright, but not dazzling. It has many reflective and refractive surfaces and is irregular, similar to pearl luster. Rayon fabrics have a pale sheen that can be harsh or metallic.
Tips 4:Soak in boiling water
When a little fiber is put into boiling water, the shape of the silk fabric does not change significantly, while the rayon fabric quickly bends and sinks. After drying, silk fabrics remain almost unchanged in length, while rayon fabrics shrink significantly.
Tips 5:Water test
Extract a little fiber, moisten it with drops of water on the left side, and then pull. Rayon fabrics generally break only in wet places, while silk fabrics may break anywhere, while chemical fibers are difficult to break regardless of whether they are wet or dry.
Tips 6:Compare the creases
Take some fibers, fold them in half and knead them repeatedly. The silk fabric has good elasticity and no creases. Rayon fabrics have significant creases that are difficult to restore. If there are slight creases but slowly recover, it is chemical fiber such as nylon.
Tips 7:Lit with fire
If you ignite a few fibers with fire, the silk fabric will burn, but it will go out when removed from the open flame, giving off the smell of burnt hair. The residue will be gray and will shatter when pinched with your fingers. Rayon fabrics continue to burn rapidly away from open flames, smelling like burning plastic. The residue is in the shape of small black balls, hard in texture and difficult to crush.
Different Weight and Price
Genuine boski fabrics have different weights, generally measured in pounds. The heavier the weight, the thicker the fabric, and the higher the price. Generally speaking, 6-pound boski fabric is the most common and suitable for all seasons. The 8-pound boski fabric is more suitable for winter wear because it is warmer. You can determine the weight of fabric by weighing or folding it.
Boski Color Fastness
Pure boski fabrics come in different colors, generally white, beige, gray, black and other natural colors. Some boski fabrics are also dyed in other colors, such as blue, green, red, etc., but these colors may affect the texture and luster of the fabric. You can judge the quality of the fabric by observing whether the color of the fabric is uniform, whether it fades, whether there is color difference, etc.
Silk Fabric
Pure boski fabric is a natural fiber woven from silk, and its main component is protein. Silk is a filament formed by air solidification of liquid spit out by silkworms. After reeling, silk spinning, weaving and other processes, it is made into various silk fabrics, such as satin, silk, crepe, silk, cotton, etc.
Rayon Fabric
Rayon fabric is a chemically synthesized or processed fiber whose main component is cellulose. There are many kinds of raw materials for rayon fabrics, such as cotton linters, wood, bamboo, bagasse, reeds, etc. After chemical treatment and mechanical processing, various rayon fabrics are made, such as viscose, cupro, acetic acid, modal, Tencel etc.
Boski Fabrics Production Process
The production process of pure boski fabrics is relatively complex and requires multiple steps such as sericulture, silk reeling, silk spinning, weaving, dyeing and finishing. Each step requires precision and strictness, and requires a high level of equipment, technology, labor, etc. requirements, so the production cost of silk fabrics is higher and the output is lower.
Rayon Fabrics Production Process
The production process of rayon fabrics is relatively simple, mainly through dissolution, spinning, weaving, dyeing and finishing, etc., which can achieve large-scale industrial production with low production costs and high output. However, the production process of rayon fabrics will also produce some pollutants, which will have a certain impact on the environment.
Different Properties Between Pure Boski and Rayon Fabrics
- The strength of pure boski fabric is higher than that of rayon fabric, but the wet strength is lower than the dry strength. It is not wear-resistant, wrinkle-resistant, easy to shrink, fade and moth.
- The strength of rayon fabric is lower than that of silk fabric, but its wet strength is higher than dry strength. It is wear-resistant, wrinkle-resistant, not easy to shrink, not easy to fade, and not easy to be mothed.
- Pure boski fabric has better elasticity than rayon fabric. It has a certain degree of resilience and is not easy to deform, but it is also easy to wrinkle.
- The thermal performance of pure boski fabric is better than that of rayon fabric. It has better thermal insulation and is suitable for winter wear. However, it is not resistant to high temperatures and is easy to burn and yellow.
- The thermal properties of rayon fabrics are worse than those of silk fabrics. They have poor thermal insulation and are not suitable for winter wear. However, they are also resistant to high temperatures and are not easy to burn or yellow.
Among the above methods, igniting with fire is the easiest method for ordinary people to master. Just cut a small piece from the purchased boski fabric and ignite it with fire. If the fire goes out quickly, congratulations, you have bought pure boski fabric. If the fire continues to burn, it is probably made of man-made fibers.Through our detailed guide, I believe you should now learn how to identify it, so hurry up and give it a try.
