Identification Method Of Silk Fabric Authenticity

Silk is generally referred to as silk, including mulberry silk, tussah silk, castor silk, cassava silk and so on. It belongs to protein fiber. Silk fibroin contains 18 kinds of amino acids which are beneficial to human body. It can help skin maintain the metabolism of the surface lipid membrane, so it can keep skin moist and smooth, and has the reputation of human "second skin".

Wearing silk clothing can also prevent ultraviolet radiation, prevent harmful gases from invading, resist harmful bacteria, and have a good auxiliary therapeutic effect on some skin diseases.

In addition, because of the special hygroscopicity and permeability, it also regulates body temperature and regulates moisture.

In the face of the multifarious hundred silk silk merchants in the market, in this age when the counterfeiters are all pervasive and the technology of counterfeiting is unfathomable, how can consumers distinguish the authenticity from the trust of the major shopping malls and franchised stores?

Product identification

China produces silk and satin, which is made up of 5 Arabia figures. The 5 numbers start from the left. The first digit represents the material number of the fabric. The total silk fabric (including mulberry silk and spun silk) is "1", the chemical fiber fabric is "2", the blended fabric is "3", the tussah silk fabric is 4, and the artificial silk fabric is 5.

It is understood that there are no silk fabrics imported from the market, such as the fabrics of fancy yarn, pearl yarn and so on, which are all made of synthetic fabrics. Therefore, there is no uniform number of imported silk fabrics.

Price recognition method

Silk fabrics are relatively expensive. They are about double to two times the size of synthetic fibers and silk fabrics. But not all expensive silk is pure silk. This is only a recognition factor, or a multi angle identification.

Lustre and handle recognition method

The samples are evenly distributed to observe the appearance. The silk has the absorbance property. It looks smooth and can not mirror. The gloss is elegant and soft. The pearl is bright, the handle is soft and elegant, the silk thread is denser, the hand scratching will have wrinkles, the higher the purity and the greater the density of silk, the better the silk handle; though the silk fabric is processed, the handle is soft, but the silk surface is dark and has no pearl luster; the chemical fiber fabric is bright, dazzling, and the handle is more stiff.

Rub the two layers of silk fabric with a slight sense of scraping.

Combustion recognition method

Take out some yarn and thread to burn. The silk can not see the naked fire and has the smell of burning hair. It shows that there are protein fibers and black dust particles. It can be crushed by hand. When the simulated silk is flame, it has plastic smell, and the hard edges will be left after the fire is extinguished.

The shrinkage rate of silk is higher. It is advisable to buy the finished product in order to choose the first gear larger than the actual demand. If it is cloth, the cloth should be put into the clear water for more than 5 hours before making, so that the cloth can absorb moisture completely and dry after soaking for second times, so that the silk will not deform after two soaking for two hours.

Pulling force recognition method

Silk has poor pulling force and can easily be pulled off; artificial silk is easily broken under wet condition; chemical fiber is stronger and stronger in humid and dry conditions.

The friction audible recognition method will rub the fabric together, and the silk fabric will produce a "silken" sound, while the fabric made of chemical fabric and other raw materials does not have such a sound.

84 disinfectant identification method

In the experiment, chemical method is usually used to identify 1 grams of silk towel into 1 moles of sodium hypochlorite solution. If it is dissolved completely, it can be judged that it is real silk.

84 the main component of the disinfectant is sodium hypochlorite. When it comes to protein fiber, it will produce dissolving chemical reaction.

In life, consumers can try 84 disinfectant to distinguish true and false silk.

Using this method, we should pay attention to controlling the specific gravity. If the amount of disinfectant is not enough, the concentration is not reached, or some of the fabrics are tight, it may not be completely dissolved.

In addition, we should know how to cherish the same time.

After the sweat is wet, the silk clothes should be washed immediately. Silk dress is made of protein and delicate health care fiber. It is not suitable to rub on rough articles and wash with washing machines.

The clothing should be reversed, under 30 degrees of water temperature, immersed in water for 5 - 10 minutes, with special silk detergent or neutral soap and so on gently rub.

If you drop a few drops of vinegar in the water, the washed silk is soft and smooth.

After washing, it is not suitable to wring away the water. It should be gently shaken and put out in the cool and ventilated place to dry.

Dry until 70%, then ironing or shaking.

It is advisable to press the temperature at 100 degrees.

When silk is not worn, camphor pills should not be used, otherwise it will embrittling easily.
