How to distinguish the advantages and disadvantages of silk embroidery fabrics, embroidery, called needle embroidery in ancient times, is a process of embroidering the needles on the textiles with embroidery needles and embroidering the needles on the textiles. Embroidery has a long history in China and has a long history. It is one of the ancient Chinese handicrafts. The Chinese hand embroidery process has been more than 2,000 years old.
How to distinguish the advantages and disadvantages of silk embroidery fabrics?
The embroidered products of the Warring States Period and the Han Dynasty unearthed in Hubei and Hunan are of high standard. In the Tang and Song Dynasties, the needles are fine and the color is rich. The embroidery is used for painting and calligraphy, and accessories. During the Ming and Qing Dynasties, the court emperor's palace embroidered work was very large, and the folk embroidery was further developed. It produced Su embroidery, Yue embroidery, Xiang embroidery and Qian embroidery, and was known as the “Four Famous Embroidery”. When embroidery is applied to silk fabrics, it is colorful and unique, and it has been passed down to the present.
Any product has high, medium and low points, and for its quality and quality, of course, there are high, medium and low differences, silk embroidery is no exception! How can we quickly distinguish the quality of embroidery lace? Here are a few ways to identify the quality of embroidery lace:
First look at the appearance. Good quality silk products, whether it is clothing, bedding, silk painting, silk scarves, etc., the lines are clear, the printing is full, the cloth surface is delicate, there will be no grainy blur and rough printing. When choosing silk products, the color is lighter or the color is natural. It is a good choice because it is not easy to fade, and some products with strong color may increase the color drop due to excessive dyeing. In addition, there is a simple test: put a piece of white cloth on the product and rub it back and forth. If it is found that the white cloth has signs of dyeing, it will show that it will fade.
Regarding the odor, the quality of the product is generally fresh and natural, and has no odor. If you open the package and smell the pungent smell, such as sour smell, it is probably because the formaldehyde or pH in the product is too high, it is best not to buy. Currently, the mandatory standard for textile pH (pH: end of note) is generally 4.0-7.5.
We can also touch its texture. The good product feels comfortable and delicate, and has a tightness. It feels rough and loose. Inferior embroidery, poor color, uneven color, unclear lines, blurred patterns, and some corners of the mouth, there may be thread head protrusions.
The various decorative patterns embroidered on the fabrics have been beautifully performed in ancient China. Most of them are beautiful and bright, and they are quite graceful and festive.
(PS: PH value refers to the residual acid and alkali content in the fabric. The relevant national standards have made clear and strict requirements on the PH value of textile products. Whether the fabric is in direct contact with the skin, the PH value is also different.
The pH value of textile products for infants and children directly exposed to the skin should be controlled at 4.0 to 7.5, and the pH value of textile products not directly contacting the skin should be controlled at 4.0 to 9.0.
The pH, commonly referred to as the pH value, is a value used to indicate the acidity, neutrality or basicity of a solution, ranging from 0 to 14. The pH of the acidic solution is less than 7, the stronger the acidity of the solution, the smaller the pH value; the pH of the alkaline solution is greater than 7, the stronger the alkalinity of the solution, the greater the pH value. Pure water or neutral solution, their pH is equal to 7.
In the textile production process, whether it is fading, scouring, bleaching, dyeing or printing, it must be fixed, reduced and cleaned. These processes require the use of large amounts of soda ash, caustic soda, pH adjusters, surfactants, etc. If the washing is not thorough, it will cause acid and alkali residues on the fabric. The pH value of the textile is determined by testing the pH of the textile water extract and is a technical indicator for controlling the pH in the production process.
