What are the main ingredients in Cotton Flame Retardant?
This product is commonly used in civilian, industrial, and industrial areas, but it is known to be flammable. In case of fire, people have developed flame retardant technology, which is called "cotton flame retardant". The use of this product, where fire prevention is required, more should be done. The ancients have studied its principles carefully, but it has not been done for thousands of years, and it has been obtained. Today, the main components and chemical principles of it are described below:
Cotton plants, the main content of nutrients. In case of open fire, it is easy to dissolve and ignite, so it is flammable, so it is made flammable by foreign objects. Flame retardant principles and methods are used to make them more efficient, so they can be combined with flame retardant. The main components of phosphorus compounds and nitrogen compounds are often phosphoric acid, phosphoramide, polyphosphoric acid, etc., or boric acid, chloride, etc., to help.
The method is mostly based on three types of phosphoric acid, including phosphoric acid, phosphoric acid, etc., or the combination of quaternary phosphoric acid grease and chloroethane phase. These formulas can be transparent, high-temperature baking, chemical transformation, and chemical-based reactions in the parts of cotton fabrics to generate fixed flame retardant molecules. The chemical system is applied to high-temperature, phosphorus, nitrogen, etc. to form a film, effectively blocking the amount of oxygen, generating moisture and non-flammable water, decomposing, and improving flame retardancy.
Tetrakis Hydroxymethyl Phosphonium salt (THPC) is also used as the main flame retardant. This material is rich in phosphorus and nitrogen in the molecule, which can form a co-combination of cotton, burning water carbonization, and combustion. Boric acid and borax are also used to promote flame retardant effect, and have both antibacterial and mildew-proof properties.
In short, the main ingredients of Cotton Flame Retardant are phosphorus and nitrogen-containing compounds, or a small amount of boron and chloride. Due to the biological interaction of high-temperature chemicals, carbon is generated in high-temperature materials, which not only blocks oxygen supply, but also suppresses the wave, which greatly improves the safety of cotton products. This is the most important thing in the mainstream flame retardant of the world.
How does Cotton Flame Retardant achieve flame retardant effect?
Cotton is a natural fiber, which is flammable in nature. In case of fire, it will be incandescent, and it will burn like firewood. However, in the past, people pursued safety and had good intentions, so they developed flame retardant techniques. What is the reason for the flame retardant, the fixed cotton fiber, to make it non-flammable in case of fire, or self-extinguishing when it burns? There are numbers, all of which are the way of chemistry.
One is that the body is flame retardant. Before spinning, phosphorus, nitrogen and other flame retardant elements are introduced into the cotton fiber, which are crosslinked by chemical reaction, so that the flame retardant components and the fiber are homogeneous. When the flame is close, the flame retardant elements are released, generating non-flammable gases, such as ammonia, phosphoric acid, etc., It can also generate carbon at high temperatures. The carbon layer adheres to the surface of the fiber, isolates the inside and outside, and protects the core from burning.
The second post-treatment method is to weave the finished cotton and apply flame retardants. Common agents such as phosphate and melamine are impregnated and pad-dyeing to impregnate the fiber. In case of fire, the flame retardant decomposes and releases non-flammable gases, one takes away heat and reduces its temperature; the other isolates air, and the flame is difficult to extend. Phosphorus-based agents generate phosphoric acid when heated, which can catalyze the dehydration and carbon generation of cotton fibers. Carbon black is like a cover, cutting off the fire circuit. Nitrogen-based flame retardants release ammonia and nitrogen when burned, dilute oxygen, and burn unsustainably.
There is also a synergistic method, combining several types of flame retardants, such as halogens, phosphorus, nitrogen, etc., to create high efficiency. The mechanism is that halogens inhibit the combustion chain reaction, and phosphorus and nitrogen promote the carbon generation layer, which complements each other.
The flame retardant power still needs to be stable and washable. Brocade clothes are used for a long time, and if they are washed frequently, the flame retardant efficiency will gradually decline. For this reason, chemists use cross-linking and curing methods to make the flame retardant and cotton fibrosis into one, which is not easy to lose. If it is a body modification, it is particularly reliable and can last for a long time.
In summary, the flame retardant of cotton depends on the delicate chemical reaction. Change its nature and solidify its quality, so that the flames are useless on cloth and silk, widely used, and beneficial to all living beings.
Are Cotton Flame Retardants Harmful to Human Health?
Cotton flame retardant, now known as Cotton Flame Retardant, is made of cotton cloth plus flame retardant. In ancient times, silk silk was the most precious, but now it is pushed cotton cloth as the top, its soft body is suitable, cool and breathable, and it is suitable for quilt clothing. However, cotton is flammable, and it is afraid of fire in clothing utensils. Therefore, later generations of craftsmen used flame retardant methods to apply it, hoping that it would not burn in case of fire, so as to increase safety. Flame retardant agents or chemical components such as phosphorus and bromine, or inorganic elements, cover different ways.
If you ask whether it is harmful to the human body, you must analyze the number of ends. First, the properties of flame retardants vary. If inorganic elements such as boron and nitrogen, most of them are slightly toxic and contact with the human body, no major harm is seen; if they contain organic phosphorus, organic bromine and other ingredients, they may precipitate with sweat, or rub with the skin for a long time, and gradually penetrate into the body. Second, organic flame retardants may not be easily released at room temperature, but in case of high temperature and friction, especially those who have been used for a long time, may gradually decompose and emit harmful gases, such as bromide and formaldehyde. Third, a few people have sensitive skin, or due to the retention of flame retardants, they may cause redness, swelling, itching and pain. Some flame retardants have been tested on animals and are actually carcinogenic, teratogenic, and affect endocrine.
Nowadays, the laws are strict, and most European and American countries control them by standards. All flame retardants that are harmful to the human body or the environment are limited to their use; however, the products sold on the market are uneven in quality, or there are prohibited goods flowing in, so when choosing, the certificate should be reviewed to avoid its harm. In general, the advantages and disadvantages of Cotton Flame Retardant to health cannot be generalized, depending on the ingredients used, testing standards and user physique. If the materials used in the product are regulated and the manufacturer manufactures it according to the law, it is generally harmless. However, for daily use, it is recommended to choose the materials carefully, wash them diligently, and not for a long time; if you feel irritated, you should stop and ask a doctor.
Therefore, cotton refractory materials are beneficial in preventing problems before they occur, but the harm is due to poor use of materials; if you discern their sources and choose carefully, you can enjoy their benefits and avoid them.
What Cotton Flame Retardant is suitable for?
Cotton products are famous for their flexibility, comfort, moisture absorption and breathability. However, they are flammable in case of fire. If there is no protection, they are easy to incinerate. Flame is difficult to control. In order to ensure peace, Cotton Flame Retardant, a flame retardant for cotton, came into being. This agent is not only applied to coarse cloth and fine silk, but also soluble in many types of cotton fabrics. To try to say its application, it can be divided into several categories.
Bedding such as quilts, sheets, and pillow towels are mainly cotton. They are always lying in the room. If they encounter fire, they are easy to burn and destroy the house. Applying flame retardants on them can delay the combustion, reduce damage and benefit the stability of the home. Clothes are also made of cotton, such as robes, shorts, pantyhose towels, and worn close to the body. If there is an accident, it will be flame retardant and self-protective to prevent the spread of fire. Children's clothing needs special care. Young children are easy to move, and if they are involved in fire candles, they are very vulnerable to disasters. Therefore, their cotton clothes and hats should be flame retardant first, which is especially suitable.
Home furnishings, such as curtains, coverings, tablecloths, etc., hang in the room, cut off light and shadow, or decorate the dining room, or set up the hall. Once burned, thick smoke will blind the eyes and disperse poisonous gas. After applying flame retardants, it can block the flame, prolong the reaction time, and facilitate risk avoidance. It is actually a choice above household and hotel.
In addition, the cotton yarn used in hospitals is a medical necessity, and mattresses, surgical fabrics, etc., all rely on flame retardancy to increase safety. Public places such as stage curtains, theater cushions, and places where audiences gather, fire is unpredictable. Therefore, Cotton Flame Retardant must be applied to prevent it.
In general, Cotton Flame Retardant is suitable for all cotton-based products, whether it is for use, bedding, household use, or medical use. After application, cotton products can maintain their flexibility and increase their self-protection energy, which is a grand measure to control disasters. Things are impermanent, and times of peace are in danger. Cotton products are made of flame retardant, and they are sincere in safeguarding people's relationships and strengthening their families.
How Long Does a Cotton Flame Retardant Last?
The flame retardant of cotton is actually used to prevent micro and gradually, and to protect it from fire. However, its lifespan is also fixed. Or ask what is the service life of Cotton Flame Retardant? Try to describe it today.
The original cotton is soft and easy to burn. It is chemically applied with flame retardant to delay the fire. This flame retardant is mainly phosphorus, nitrogen, boron, etc., which is impregnated in cotton fibers, or chemically modified to make it difficult to burn in case of fire. The flame retardant is gradually damaged by the moisture and dryness of the climate, the loss of washing and the passage of time. As a matter of common sense, if it is cleaned frequently and rinsed repeatedly, the flame retardant will be diluted, resulting in the gradual decline of the effect. The reason is that if the paint is applied to the device, it will peel off after a long time; as for those who have not been washed or dried, their lifespan will increase.
The textile industry has said that the flame retardant cotton commonly used in homes or construction sites can guarantee the flame retardant effect for about three to five years. If it is used more often and washed frequently, its effect may be reduced to two or three years. If the standard is renewable flame retardant, it needs to be tested according to the certification standard, but it should not exceed five years. After that, it should be reprocessed or more novel. Ask about its longevity, is it only the material quality? There is still a storage environment and construction technology, all of which are related to its effectiveness.
Flame retardant institutions are often advised to use: After three years, it must be checked. It can be seen that although its appearance is considerable, the flame retardant inside may be disabled; you can take separate samples to test the combustion and observe its reaction. If you see that it is no longer delayed in case of fire, it must be treated immediately. The flame retardant of cotton cover is a safety measure, and if it fails to be effective, the protection is virtual.
Maintenance should also not be ignored: it is advisable to avoid sun and rain, do not leave it at high temperature for a long time, and also prevent damage from sharp objects. The reason is to maintain the combination of flame retardant and fiber, so as not to let it escape. In case of replacement or rewashing, you must follow the technical guidelines to ensure long-term safety.
In summary, cotton flame retardant products can be guaranteed to be effective within three to five years if they are properly applied. If they are overdue, they should be carefully inspected. It is up to people to save their safety and avoid the risk of fire forever.
