Silk charmeuse satin fabric is an all-silk, with weak twist on warp, strong twist on weft, weaving with satin weave structure, bright satin texture on the front, and double crepe on the reverse The silk satin charmeuse fabric is thicker than the double crepe. The current commonly used silk charmeuse satin fabric specification is 14656, which is a relatively thin silk charmeuse satin fabric. 14101 is a relatively thick silk charmeuse satin fabric,

which is a regular fabric in all true silk fabrics. The bright satin surface is very noble, has a smooth feel, is elastic, and has a dense structure. The fabric of the silk charmeuse satin fabric has shrunk due to the weft and strong twist. The rate is relatively large, and the gloss decreases after launching. Crepe satin refers to a type of all-silk silk satin varieties that have strong weft twists (2600 twists), no warp twists, and a fabric structure of five satin.

Common silk charmeuse satin fabric specifications include 14547, 14654, 14548, and other common thicknesses. At the same time, common thicknesses are 12m, 16m, 19m, and 30m. The surface of silk charmeuse satin fabric has fine and even wrinkles. The texture is soft, smooth, bright and soft, flexible, comfortable, cool, and breathable.

1. Comfort.

True silk satin fabric is composed of protein fibers, has excellent biocompatibility with the human body, and has a smooth surface. Its friction stimulation coefficient to the human body is the highest among all types of fibers, only 7.4%. Therefore, when our delicate skin comes into contact with the smooth and delicate silk charmeuse satin fabric, it takes care of every inch of our skin with its unique soft texture and according to the curve of the human body.

2. Good hygroscopicity and dehumidification.

Silk charmeuse satin fabric protein fiber is enriched with many amine, amino and other hydrophilic genes, and because of its porosity, it is easy for water molecules to diffuse, so silk fabric satin can attract moisture or emit moisture in the air, and maintain a certain amount of moisture. In summer, the sweat and heat emitted by the human body can be quickly dissipated, making people feel extremely cool. It is precisely this property that makes silk charmeuse satin fabric more suitable for direct contact with human skin as bedding.

3. Keep warm.

Silk charmeuse satin fabric not only has good heat dissipation performance, but also good thermal insulation. More than 38% of the seemingly solid silk charmeuse satin fabric is actually hollow. There is a large amount of air in these gaps. This air prevents the heat from being emitted and makes the silk charmeuse fabric have good thermal insulation.

4, anti-ultraviolet.

Tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk charmeuse satin fabric has better UV resistance. And UV is very harmful to human skin.

5. Sound absorption, dust absorption and heat resistance.

Silk charmeuse satin fabric has a high porosity, so it has good sound absorption and breathability, so in addition to making clothing, it can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall coverings, etc. Decorating the room with silk decorations not only keeps the room clean, but also keeps the room quiet. Because silk charmeuse satin fabric has hygroscopic and dehumidifying properties, as well as moisturizing, air-absorbing and porous properties, it can also adjust the indoor temperature and humidity, and can absorb harmful gases, dust and microorganisms.lets more look at the silk satin fabric

A good printing and dyeing process determines the color fastness of fabric and clothes. The following are common processes on the market: reactive dyes Silk charmeuse The dying used in traditional printing and dyeing processes are mostly direct, acidic and neutral dyes. Most of the color fastnesses are onlylevel 3, and the deep color is still far from this index. Therefore, to make real Silk charmeuse truly reach the goal of washing and wearing, it is necessary to solve the problem of color fastness.

At present, there are fatal weaknesses in the dying and printing processes used in Silk charmeuse printing and dyeing, which are mainly manifested in the following five aspects:

(l) Most dyes used in Silk charmeuse printing and dyeing are weak acid dyes, neutral dyes and direct dyes. , Printing, dyeing and taking process cause pollution to the environment. Such as: excessive metal chromium ions in the production process of neutral dyes seriously pollute the environment. Some countries in Germany and Europe have proposed strict control of the residual amount of heavy metal ions in textiles.

(2) The fastness of wet treatment is poor. Generally, the dark and medium colors are about 2 to 3 grades, and the dyeing and printing of individual dyes are only about 2 grades. The performance of taking it can not be washed in the same bath with other months and equipment. At the same time, it will cause light color due to fading. Get old.

(3) The sun fastness is poor, generally only about l-2 grade, especially the bright green lotus, lake blue, brilliant blue and other colors, it will fade after a summer, lose the timeliness of taking, and cannot be consumed by the majority Accepted by the person.

(4) With the gradual maturity of anti-shrinkage and anti-wrinkle finishing technology, the disadvantages of washing, such as fading, staining, and oldness, are becoming more and more prominent, and it does not solve the problem of color fastness. It is really "washable and wearable" in the true sense.

(5) Whether it is a domestic product or an export product, it is generally required to print and dye real Silk charmeuse with high fastness (washing and soaping fastness requirements above 4; wet rubbing fastness above 3), the current factory can not be industrialized production. There is an urgent need to solve this problem. In recent years, with the development of the chemical industry, a number of new reactive dyes have been developed, and the performance of printing and dyeing has been rapidly improved. The reactive dyes have a high dyeing rate, level dyeability, fixation rate, improvement rate, and stability. There have been great improvements in terms of performance and process sensitivity, which laid the foundation for the development of reactive dye printing and dyeing processes. Therefore, it is the most important task to be solved in the current silk charmeuse industry to accelerate the resolution of the weakness of the Silk charmeuse products such as fading and aging, accelerate the research on the printing and dyeing process of the reactive dyes of Silk charmeuse, and develop new high-fastness Silk charmeuse products.

Adding environmentally friendly reactive dyes Increasing environmentally friendly dyes not only requires no pollution or less pollution in the production process of dyes, but the reactive dyes produced by the project are less polluted during the printing and dyeing process, and the processed clothing must meet environmental protection requirements. Some of the prohibited dyes have been substituted, and a batch of reactive and reactive reactive dyes have been developed in recent years.

Reactive dye dyeing process :

Acid bath method The acid bath method is suitable for the dyeing of Silk charmeuse and viscose jacquard cross fabrics. The neutral bath method or alkaline bath method will make the viscose pattern stain or color. Process flow: fabric treatment → dyeing → pickling → soaping → water washing → cold water roll. The application of reactive dyes on textile fibers should have at least the following conditions: high water solubility; high storage stability; not easy to hydrolyze; high reaction to fiber and high fixing rate; chemical stability of the bond between dye and fiber High, that is, it is not easy to break the bonds during use. It has good diffusibility, level dyeing and good dye penetration; various dyeing fastnesses, such as sunlight, climate, washing, friction, chlorine bleaching resistance, etc. . There are more special requirements for dyes for silk satin printing:

Printing process flow: grey Silk charmeuse preparation → printing → drying → steaming → washing → soaping → washing → drying.

(l) Steaming: After the fabric is printed and dried, it needs to undergo a steaming process to dissolve most of the dye remaining in the slurry film in the presence of water, transfer to the fiber, and diffuse into the fiber. The selected steaming equipment is to hang the fabric on the star rack and put it into the steaming box for steaming.

(2) Soap washing: The fixing rate of general reactive dyes is only about 70%, and the high ones are only 80%. Unfixed dyes dissolve into the washing liquid during washing, and when the concentration of dye in the washing liquid is high, Stained fabric due to fiber absorption. Therefore, reducing the dye concentration in the wash solution as much as possible is a measure to reduce contamination. First wash with cold water, then hot water, soap, and finally hot water and cold water.
