What are the main ingredients of Flame Retardant for T/C Blends?
T/C blended fibers are interwoven between cotton and polyester. In order to make them flame retardant, flame retardants are often used to treat them. In today's world, melamine phosphate, aluminum hydroxide, halogen organics and phosphorus and nitrogen-based compounds lead the way, but most of them are phosphorus and nitrogen-based. Such ingredients have both high-efficiency and long-lasting characteristics, which are not easy to deactivate, and less damage to the physical properties of fabrics.
Melamine phosphate, with phosphorus molybdenum and phosphorus and nitrogen complementation, can not only promote charcoal formation, but also block heat. Polyester is prone to melt and drip, while cotton is flammable. The coexistence of the two at high temperatures often increases the combustion damage. Therefore, phosphorus and nitrogen flame retardants are used in T/C blends. The mechanism is threefold: first, it can form carbon on the fiber surface to isolate the fire source from contact with air; second, it can decompose at high temperature to release inert gas, dilute oxygen concentration, and slow down combustion; third, it can generate a non-combustible atmosphere and block heat transfer. Common chemicals such as dihydrourea phosphate and urea phosphate also include hypophosphite, ammonium polyphosphate, quaternary ammonium salts, etc.
Aluminum hydroxide and magnesium hydroxide are inorganic compounds that can decompose and release water vapor at high temperatures to cool the fiber surface and dilute oxygen in the flame zone. Although the effect is significant, the dosage is extremely high, which often affects the softness of fabrics. Halogen flame retardants such as bromide, although their flame retardant properties are outstanding, have toxic hazards and are increasingly used less. The latest trend is towards halogen-free, environmentally friendly phosphorus and nitrogen system flame retardants, which not only meet health needs, but also have long-term effects.
To sum up, the main components of T/C blended fiber flame retardants are mostly phosphorus and nitrogen as the core, and with an appropriate amount of auxiliary agents, the fibers are fire-resistant and flame-retardant without damaging their original properties. Using phosphorus and nitrogen to help each other and form carbon insulation, supplemented by stable decomposition, not only keeps the safety of the fibers, but also protects the health of the wearer. Its subtle and widely used, it is an indispensable element in today's textile industry.
How to use Flame Retardant for T/C Blends?
Flame Retardant for T/C Blends must follow the technological process and operate strictly to make it fully effective. First, choose high-quality flame retardants, depending on the type of fiber and the needs of the fabric. T/C Blends, that is, polyester-cotton blends, need to take into account the flame retardant properties of polyester and cotton. The preparation should be uniform, fully dissolved, and no impurities should be deposited.
Usage includes dry coating, wet dipping, etc. Wet method is often used as the main method, which is easy to operate and has a significant effect. During operation, first dilute the flame retardant with water in a ratio to mix evenly. The T/C fabric is thoroughly soaked in the liquid, so that the solution penetrates deep into the fiber. After impregnation, the cloth is produced, the residual liquid is lightly squeezed, and the pressure is moderate, which not only maintains the content of flame retardant liquid, but also prevents the deformation of the fabric. Then it is dried at constant temperature, and the temperature control is appropriate. If it is urgent, it is easy to cause decomposition, and if it is slow, it is time-consuming and unhelpful. After drying, it is feasible to cure, which promotes the flame retardant to adhere firmly to the fiber. The curing temperature and time are different according to the specific formula, and must not be ignored.
In addition, spraying is also a commonly used method. The flame retardant is evenly sprayed on the surface of the T/C fabric with a high-pressure sprayer, and then dried and cured. This method is suitable for the surface treatment of the finished product, which is fast and convenient. However, it penet
Or use a post-finishing process to add flame retardant to the end of the textile process. Use with softener and antistatic agent to take into account feel and performance. All processes should be uniform, with moderate twist, and dead corners should not be missed.
After flame retardant treatment, its effect must be tested. Vertical combustion method, limiting oxygen index method, etc. can be used to prove that its flame retardant performance is up to standard. Ease gas and waste liquid should be properly handled, which is environmentally friendly and responsible.
In short, the T/C Blends flame retardant method needs to be properly proportioned, well-crafted, and well-tested in order to achieve high-quality.
Does Flame Retardant for T/C Blends affect the physical properties of fabrics?
Burning prevention agents are used in cotton-polyester blended fabrics, which have a significant impact on their physical properties. The physical properties of fabrics include strength, elongation at break, wear, and feel. When applied to burning prevention treatment, burning prevention agents contain more organic phosphorus, nitrogen or halogens and other chemicals, which can endow fabrics with the function of suppressing burning. However, when they interact with fibers, the properties of fabrics will change more or less.
Burning prevention agents penetrate the fiber structure, causing subtle changes in the internal tissue tightness of the fibers. In terms of strength, burning prevention agents can easily weaken the hydrogen bonds between fiber chains and reduce the strength. Experiments show that the strength after treatment is lower than that of the original cloth, because the fiber surface is affected by chemical reactions and is easy to break. With the help of high temperature and high pressure, the fiber is easy to age, so the physical strength decreases. The elongation at break is also damaged, and the flexibility of the fabric is weakened, and it is easy to crack.
However, in cotton-polyester blends, the polyester part has better chemical resistance, and the impact is lighter than that of cotton fibers. Burning prevention agents focus more on the bonding of cotton fibers, and have relatively little negative impact on polyester. However, the overall fabric performance is still reduced. Looking at the wear performance again, after the burning prevention treatment, the surface layer of the fiber becomes brittle and wear-resistant. In terms of feel, the burning prevention agent is easy to block the fiber gap, and the fabric is thick, rigid, and loses its original flexibility.
In addition, burning prevention treatment may affect the color fastness of the cloth surface, and some agents can change the color and affect the appearance. In long-term use, the burning prevention effect is weakened with washing, and the physical properties are further attenuated. However, everything has advantages and disadvantages. If the appropriate process is taken, the agent is carefully selected, and the application method is improved, the effect can be weakened, and the balance between burning prevention and physical properties can be achieved.
In summary, the burning prevention agent has a significant impact on the physical properties of cotton-polyester blended fabrics. However, with scientific treatment, it is still possible to achieve both.
What is the environmental performance of Flame Retardant for T/C Blends?
Flame Retardant is used in T/C blended fabrics, and its environmental protection performance has attracted much attention from the world. For T/C blends, cotton and polyester are used together, and its flame retardant treatment has its own differences. In this discussion of its environmental protection performance, it is necessary to carefully consider the three ends of raw materials, processes and applications, in order to penetrate the essence.
If halogens or organophosphorus compounds are used in flame retardants, they are often prone to environmental pollution, and generate toxic gases when burned or discarded, which damage the ecology and human health. These manufacturers tend to be new flame retardants that are halogen-free, low-toxic or degradable, such as organophosphates, nitrogen-based or inorganic. Their toxicity is low, bioaccumulation is small, and the harmful substances that escape during manufacture and use are significantly reduced. All kinds of flame retardants can give textiles excellent self-extinguishing performance without compromising the softness and comfort of fabrics, which is very suitable for today's green development.
In the manufacturing process, water-based carriers and synergistic additives are used to effectively reduce organic solvent and VOC emissions, and waste liquids can also be recycled to reduce damage to water bodies and the atmosphere. In flame retardant finishing, if nano-materials are selected, they can achieve high efficiency in small amounts, consume less resources, and properly dispose of waste. In addition, many flame retardants have passed international certifications such as REACH and OEKO-TEX, which meet relevant regulations and standards, proving that they have minimal harm to the environment and human body.
At the time of application, the T/C blended fabric treated with flame retardants has very little migration and precipitation during daily washing and wearing, and is not easy to pollute soil and water sources. Most of its degradation products are non-toxic, and can also be naturally decomposed into water and carbon dioxide, which is not harmful to the environment. However, flame retardants are ultimately chemicals, and they should follow reasonable dosages and safety standards in order to take into account flame retardant effect and environmental protection.
To sum up, today's Flame Retardant for T/C Blends has outstanding environmental performance if it takes into account material selection, process and specifications, and conforms to the general trend of green development. Only through continuous technological innovation and careful examination of the full life cycle impact can we truly achieve the unity of textile flame retardancy and ecological safety.
Can Flame Retardant for T/C Blends pass common flame retardant testing standards?
Cotton and polyester blended fabrics, with their soft and durable lids, are widely used for clothing and quilts. However, due to the fear of fire, ancestors have explored and developed a variety of flame retardant processes to block their combustion. Today, on whether Flame Retardant is used in T/C Blends, whether it can meet the common flame retardant test standards, I would like to apply it below.
Today's flame retardant test standards are international such as ISO 15025, ISO 6940, ISO 6941, domestic GB 8965, GB/T 5455, and American standards include NFPA 701, ASTM D6413, etc. Although the standards are slightly different, they all belong to the main points of assessing the charcoal length, continued combustion time, droplet condition, and residual flame phenomenon of fabrics after being exposed to fire. T/C Blends are blended with natural fiber cotton and polyester. Polyester is naturally fusible and flammable, and cotton is easy to charcoal in case of fire. The flame retardancy of its blended fabric is inferior to that of cotton. People knew this in the past, so Flame Retardant was specially developed for blended fabrics to meet safety needs.
The flame retardants sold in Jia today are mostly phosphorus-based, water-soluble, and reactive. The treatment process is either dipping and drying, or if the stock solution is mixed, it can also give the fiber flame resistance. If the chemistry and processing are both high-quality, the surface layer of the fiber will form a barrier, which will be charred in case of fire, delaying or interrupting the spread of flame retardant, so the flame retardant performance of T/C Blends can be greatly improved. If applied in accordance with the prescription, the precise temperature control ratio, and tested by standard procedures, it can often meet the requirements of mainstream test specifications such as ISO GB. The measured table shows that the carbonized length of T/C fabrics treated with phosphorus and nitrogen flame retardants is often less than the standard limit value, and the residual flame time can be significantly reduced. Without molten droplets, its performance can always pass GB/T 5455, ISO 15025 and other flame retardant tests.
However, the effectiveness varies depending on the type of flame retardant, the treatment method, and the thickness of textiles and the ratio of cotton and polyester. If the dosage is insufficient and the process is unbalanced, it may be difficult to meet the strict standards of high-level protection. It is also necessary to consider the fastness and durability of washing to ensure that the flame retardancy will not deteriorate with washing.
In summary, T/C Blends can pass the common flame retardant test standards after proper Flame Retardant treatment. If used properly, it can also achieve high safety. However, it is necessary to carefully select the process and materials according to the application and standard, and then use the standard test as the guarantee.
