Application Of Silicone Rubber In Textiles

Buffer air bag
The United States used the silicone rubber as a cushioning balloon coating material launch Pathfinder Mars probe in the end of 1996. On the one hand, the lowest temperature of the surface of Mars is -83 ℃, thus requiring balloon coating material has good low-temperature rigidity; On the other hand, when the airbag inflator discharges high-temperature gas at a high speed, the strength of the airbag material is able to withstand an instantaneous strong impact load in a high-temperature environment. Practice has proved that silicone rubber successfully resisted the harsh space environment, the detector successfully delivered to the surface of Mars. Silicone rubber has excellent weather resistance,it is also used in the car’s airbag, so as to effectively prevent the aging of the balloon coating to reduce the function of the balloon, the balloon in place after a long time can still be effective work. In addition, the buffer airbag is a precision airdrop, unmanned aerial vehicles landing areas of important components, at present, many people have carried out related research on this subject, the same balloon coating materials made of its stringent requirements, compared to other rubber Or coating materials, silicone rubber is the ideal choice.

Softening agent
Softening agent is a kind of textile auxiliaries that can adsorb on the fiber surface, improving the smoothness of the fiber, making the fabric have a comfortable feeling. Silicone softening agent originated in the the end of the 1950s, so far, the development has gone through four stages: (1) the United States Dow Corning emulsified polymerization directly to produce hydrocarbon-based silicone oil firstly, that marked the birth of the first generation of silicone softening agent, but because of its use of mechanical emulsification method directly to emulsify the silicone oil, silicone oil does not contain active groups, which combined with the textile is not strong, and not washable. (2) On this basis, the researchers developed the metal as a catalyst, with a hydrocarbon-based seal of the second generation of silicone softener, which is still a single function, easy “Floating oil and demulsification”, in the beginning before the industrialization of the third generation silicone softener replaced, before the start of industrialization was substituted with the third generation of silicone softeners; (3) Third-generation silicone softening agent is incorporated into the silicone backbone by the presence of reactive groups, these reactive groups can improve the soft effect, increase the fabric washable ability.(4) With the improvement of clothing requirements, the researchers introduce more active groups into the silicone main chain, so that softening agent really applied to all kinds of fabric. At present, some people have been modified silicone softening agent, and its role in the textile industry is growing.

Fire – resistant insulation materials
The principle of thermal insulation cloth in textile products is different, but there are two kinds of: One is the use of functional particles plus resin for processing; the other is the use of coating materials coated on the fabric surface. Silicone rubber as a high temperature resistance material, is an important insulation coating material.Some people had researched silicone rubber aluminum insulation cloth in the early 1980s, fiberglass as base fabric, coated with silicone rubber in the surface, and then through the vacuum spray technology to foil an aluminum layer. This insulation cloth can be in -60 ℃~ 250 ℃ long-term working, generally used in aircraft cockpit, umbrella cabin and booster cabin and other parts need to be insulated. Silicone coated glass fiber fabrics can be used as high-temperature anti-corrosion conveyor belt, some high-temperature protective gloves, asbestos insulation blanket, insulation blanket, high temperature service fabrics, glass fiber fire cloth and other products.

Insulation Materials
Silicone rubber coated fabric has a high electrical insulation level, which can withstand high voltage load, so as to be made of insulating cloth, sleeving and other products. In the electrical industry, insulating tape is a commonly used material, a lot of insulating tape is produced by rubber coated fabric, but there are many kinds of ordinary rubber can not meet the stringent requirements of the electrical industry, such as resistance to high voltage performance, adhesive properties, adhesion of hot air aging and anti-corrosion properties of metal, but the silicone rubber has advantages in these areas .

Silicone printing for textiles is a new hot spot in the textile industry in recent years, through the screen printing, silicone can be firmly attached to the fabric surface. Screen printing Silicone is widely used, its design has a strong three-dimensional, soft, printed pattern has a high peel strength, abrasion resistance, brightness, also has a waterproof, anti-skid and high temperature resistance. As the silicone rubber are easy to color, bright color, solid, its clothing, clothing accessories, shoes and hats, luggage and other handbags and other textile products are widely used.

Lace / ribbon dripping
For some clothing, especially women’s underwear, stockings, etc., need to do some anti-skid treatment, to prevent clothing slippage. Lace has become an important decorative women dress, high-grade women’s underwear, stockings roots will be modified with lace, but this part often occurs slippage, the use of silicone rubber dispensing process came into being. Silicone rubber treatment can achieve rounded, right-angle effect, three-dimensional sense of strong, excellent tear resistance, and contact with the human body comfort, both to ensure the beauty of clothing, but also to ensure its functional role.

Silicone cloth
Silicone cloth is a kind of high-performance and multi-purpose textile composite material, which is made of high-temperature resistant and high-strength glass fiber fabric and compounded by special technology. It is widely used in aerospace, chemical, petroleum, Equipment, machinery, metallurgy, electrical insulation, construction and other fields. Silicone cloth can also be used as the aforementioned fire-resistant insulation materials and insulation materials used, in addition to high temperature insulation, its main performance characteristics has high strength, soft and toughness, tailorability, chemical corrosion resistance, oil and water resistance. Some people had researched the performance of silicone cloth as a thermal gasket, and found that silicone cloth can not only ensure the insulation, but also can improve the thermal conductivity of insulation gasket, coupled with the strength of silicone rubber itself, making it a good performance in all aspects. Silicone glass fiber cloth coated with nickel chromium can be made into the aviation equipment, instrumentation often used in heating elements, in some of the more large products called electric blanket, its role is to rely on energy heat, by temperature control system to control the operating temperature of the instrument.

other aspects
The silicone rubber surface has a high friction, it can be coated on the surface of some anti-skid pad, anti-skid effect is better, such as the bath mat, car mats, etc. In addition, in some special clothing, the body needs to focus on the protection of parts coated with a certain thickness, a certain shape of silicone rubber can improve people’s wear safety, such as racing suits knee, elbow, shoulder and other parts.

(1) In addition to silicone rubber has excellent temperature resistance, weather resistance, good water repellent properties and corrosion resistance, but also has a very good electrical insulation, compression elasticity and vibration absorption capacity, these excellent properties of silicone rubber In many areas are widely used. In the textile field, silicone rubber can be applied in three categories of textile products, silicone rubber has become an important raw materials in textile industry.

(2) Silicone rubber is nontoxic, it does not cause pollution, and also suitable to replace the additives( will cause pollution) of the finishing process, while improving product quality, so silicone rubber will be widely used in textile finishing processes.

(3) The current technology can dye the color for silicone rubber,and it can change the color of silicone coated fabric to change the clothing color. Silicone surface is not easy to contaminate, it’s suitable for winter garments fabric. It’s believed that through the development of scientific research, this technology can be applied in textile products.
