The Misunderstanding Of Silk


The whiter the silk, the better ?


Before the dyeing or printing, a process of degumming is required. The raw silk produced in this process is natural white. This process uses weak bases, soaps, and reducing bleaching agents or oxidizing bleaching agents. The white obtaine

d is a kind of ivory white like pearl, we call it natural white.

If the silk fabric is not for dyeing or printing, but directly used to make white silk cloth, in addition to the above process, it is possible to perform whitening treatment according to customer needs, which is to use some fluorescent brighteners in fabric refine process. This whiteness is more dazzling, white like a piece of white paper. Instead of ivory white.

Fluorescent brightener is a kind of printing and dyeing auxiliary that is allowed to be used all over the world, as long as it is not abused, ornot used in children's underwear, but the fact is that natural white silk is indeed more environmentally friendly and healthier.


Mulberry silk is more expensive and scarce ?

1. Mulberry silk: It is mainly artificially fed, also called domestic silkworm. The main ingredients are protein and amino acids. The silk is delicate. It is the first choice for high-end silk garments, duvet covers, sheets, scarves, etc.

2. Tussah silk: Also called wild silk, it is a kind of silkworm that grows in the mountains. Due to the variability of the climate, wild silk has a much higher UV resistance than the silkworm, and its protein and amino acid content is more than ten of that of mulberry silk. Times. In 2007, the Ministry of Agriculture of China listed wild silk as one of the country's rare resources, independent of other silks. Because the silk fiber of wild silk is slightly thicker and has good resilience, it is the first choice for quilt.

In addition, the cross section of tussah silk has a porous structure, while the mulberry silk has a dense structure. Tussah silk has certain advantages in terms of moisture absorption, breathability, fluffy and warmth retention, and it is better than mulberry silk in terms of strength, corrosion resistance, light resistance, and moisture absorption.

Mulberry silk has become the best choice for silk garments due to its fine texture, bright luster and good dyeability; Tussah silk is the best choice for silk clothing; Tussah silk is unique in terms of its bulkiness, excellent antibacterial properties, anti-ultraviolet and radiation resistance, moisture absorption, air permeability, and temperature adjustment. The function is the preferred raw material for making handmade carpets. So the real situation is that tussah silk is scarcer.


Is silk not suitable for winter use?


Before explaining this problem, we must first understand the fact that the body temperature has a great relationship with the air humidity. The effect of humidity on the body temperature can be simply attributed to making colder and hotter. 38% of the silk structure is hollow. About 1/3 of the silk is hollow and can absorb 30%-50% of the moisture without feeling wet. As the inner temperature rises, the human body will sweat. The hot body temperature makes the moisture evaporate through the silk. , Evaporation will absorb heat and make people feel cool and comfortable. Therefore, in the hot and humid summer, we will feel cool when we use silk quilt. In winter, the hollow structure of silk can isolate the external cold air and keep the skin dry, so it has good warmth retention; it also keeps us warmin the whole winter. a silk quilt of the same weight is warmer than a cotton quilt.


Mulberry silk and real silk are not the same thing ?


Mulberry silk is a kind of real silk, which includes mulberry silk, tussah silk, castor silk and so on.

Just like tableware includes bowls, plates, and plates.

Silk is a big category, while mulberry silk is a small category. However, because mulberry silk is the best-performing, commercialized, and sold most, the general market directly calls mulberry silk as real silk.

If anyone sells tussah silk, that will definitely be marked it out. If not specifically marked, it is mulberry silk.

Take a look at the difference between silkworm and tussah silkworms:


Real silk is slippery & shiny, neither slippery nor shiny is fake ?


The silk fabrics are divided into 14 categories and 43 sub-categories. There are roughly twill, habotai, taffeta, chiffon, crepe, georgette,crepe satin, stretch crepe satin and etc.

For example, the following crepe de chine:


There is also a misunderstanding about plain satin, that is, people think that plain satin is smooth on both sides, but in fact, only one side of plain satin issmooth.

The silk does not fade ?


Real silk will fade because the dyeing stuff used in real silk is different from other fabrics. It is a reactive dye. The real silk is relatively fragile. In order to reduce the damage to the real silk, the fixing ability is slightly reduced.

The silk fades when washed for the first time, there will be floating colors, especially for deep red and blue color,the color fading is obvious. But by the second wash, no color fading can be seen.


There are no wrinkles in the real silk ?

Except for cotton and linen, real silk is the easiest to wrinkle, but after ironing, it can return to its original smooth and flat.

Generally, 25 mm or 30 mm is suggested for silk bedding sets , which is thicker and relatively not easy to wrinkle. As for the silk pajamas, most of them are 19 mm, which is natural to wrinkle easily, but it does not affect the wearing experience.


The silk is very soft ?


Silk is not inherently soft. There are many processing steps. Raw silk reeled, soaked and degummed at 40°C, turned, combined, steamed, and woven. Beforethese process, silk is not soft at all, also silk will become rough and not smooth after printing or dyeing, an important step to change the roughness of silk is to add softener.

If the amount of softener is too much, it will be verysoft, and if it is less, it will be little rough. When you receive a silk scarf or clothes that feel hard, you will get soft after washing it a few times!
