Preparation Method
Terephthalic acid and ethylene glycol were selected as raw materials, phosphorus-based flame retardants were added, and blended in proportion. Under high temperature and high pressure, the two-step reaction of esterification and polycondensation was carried out. At first, phosphorus-based compounds were blended with polyester monomers in the reactor, and the temperature gradually rose to form an intermediate ester body. Then antimonide was used as a catalyst to promote the condensation of ester groups and gradually polymerize into polymer chains. The catalytic mechanism is that antimony ions activate carboxyl and hydroxyl groups, speed up the condensation reaction and reduce the formation of side reactions. After the reaction is completed, the flame retardant masterbatch of polyester is precipitated at low temperature, and the shape is uniform. The obtained polyester has flame retardant properties. After being processed into fibers, it can also maintain its durable flame retardant effect when
Chemical Reactions & Modifications
Dye Bath Polyester Durable Flame Retardant, which is used in the bath dyeing of polyester fibers to study its properties, is based on organic phosphorus and nitrogen compounds as the main body, through the reaction in the bath, penetrating the micro-gaps of the fibers. The reaction is at high temperature, and the molecular chains are cross-linked to form a dense structure. Covered with flame retardant groups, it not only enhances the anti-inflammatory ability, but also retains the freshness of the original color. The modification method uses nucleophilic and electrophilic substitutions to break weak bonds and build new connections, resulting in the attribution of phosphorus and nitrogen elements to the main chain or side groups. This system does not damage the strength of the fibers, nor does it lose physical properties, and the flame retardancy is long-lasting. Bath dyeing reaction is simple, synergistic, and does not require re In case of fire, it decomposes and generates phosphoric acid, giving the fiber a carbon layer, which is oxygen-resistant and flame-resistant. It is the benefit of polyester to obtain high-efficiency flame retardancy, and both the wealth industry and the civilian use have made significant achievements.

What are the main ingredients in Dye Bath Polyester Durable Flame Retardant?
Dyeing bath polyester is durable and flame retardant, and it is also used in the flame retardant finishing of polyester. Examining its main components, there are many phosphorus-based compounds, especially phosphorus and nitrogen-based flame retardants. This is important, the performance is fixed, the resistance is high, and it is not easy to wash and lose, so it is durable. Used in dyeing baths, it can combine polyester molecules to form a solid or cross-border, so that the flame retardant function is both long-lasting and efficient.
Phosphorus retardant, its common use is such as melamine phosphate, polyphosphoric acid, etc. Melamine phosphate contains nitrogen and phosphorus heavy elements, which are highly susceptible to decomposition, precipitate to form non-flammable molecules, dilute flammable molecules, and form brittle and dense carbon on the cloth surface. Carbon can block the source of oxygen and spread the fire. Phosphorus element can catalyze the carbonization of polyester molecules under high temperature parts, increasing the stability. In addition, some flame retardants also contain elements such as carbon and silicon, or help flame retardant, or reduce carbon solidification, which improves its washing and wear resistance.
Dyeing bath method, it is necessary to make the flame retardant particles are all divided into the dyeing bath, and the high temperature and high temperature parts are used to insert them into the polyester parts. In this way, the flame retardant elements are integrated into the body, and it is not easy to fall into the environment after daily washing and wearing. In this technology exhibition, there are still those who add silicone and other ingredients to improve their durability and flexibility. In addition, its core ingredients are mainly phosphorus, nitrogen, silicon and other elements, and polymer technology is used to match the flame retardant efficiency, which is the essence of dyeing bath polyester durable flame retardant.

How is the Dye Bath Polyester Durable Flame Retardant?
Dye Bath Polyester Durable Flame Retardant is a special agent used to enhance the fire resistance of polyester fibers in the modern textile industry. The method dissolves the flame retardant agent in the dyeing bath, and penetrates the agent into the fiber through high temperature and high pressure to form a strong chemical bond, resulting in the flame retardant function of the fiber body, which is not only comparable to the surface coating method. The flame retardant performance of the polyester made by this method is stable for a long time, and it will not be damaged with washing and time. The agent and the fiber chain are interlocked, so that it decomposes and releases non-flammable gases when burning, isolates oxygen, and slows down the burning speed. Or form a carbonized layer to wrap the fiber and contain the spread of fire. Its ignition point is significantly higher than that of untreated ones, self-extinguishing in case of fire, extinguishing when the fire is separated, and the generation of smoke and toxic gases is also slowed down. Compared with traditional flame retardant processing, the safety is better.
Today's tests follow international standards, such as ISO 15025, GB/T 5455, etc., to evaluate the combustion performance of fabrics. The measured combustion length is short, the damage area is small, and it meets the requirements of flame retardancy. And after multiple washes, the flame retardant efficiency is still the same, and the durability is significantly better than that of surface-treated products. The fabric feels and color change little, and it does not damage comfort. It is suitable for all kinds of high safety requirements or public places, such as planes, trains, hospitals and hotels. Compared with the coating method and the finishing method with insufficient durability, the Dye Bath method is more tightly combined with the polyester molecule, so the practical benefits are particularly obvious.
Alas! Polyester fiber is treated with this technology, and its fire protection performance is greatly improved. It has the beauty of durability, environmental protection and practicality. It is actually the best choice for modern textile flame retardant technology. However, it should follow the rules and design rationally to ensure its flame retardancy, comfort and economy, so as to live up to the will of scientific and technological progress.

What Dye Bath Polyester Durable Flame Retardant is suitable for?
Dye Bath Polyester Durable Flame Retardant, translated as a durable flame retardant auxiliary for polyester dyeing, is a product of modern industrial civilization, specially designed to give flame retardant properties to polyester fibers. Polyester is very heat-resistant by nature, and it is easily damaged in case of high temperature flames. Its flame retardancy depends on post-processing improvement. It is suitable for many polyester dyeing processes, especially high temperature and high pressure dyeing, atmospheric pressure dyeing, pad dyeing and dip dyeing.
High temperature and high pressure dyeing method, which uses a high temperature of about 130 degrees Celsius and high pressure to promote the full combination of dyes and fibers. This method is often used for dyeing of polyester natural or dark colors. If this durable flame retardant additive is added to the dyeing bath, it can kill two birds with one stone in dyeing and flame retardant, so that the flame retardant components are deeply penetrated into the fibers, and the effect is long-lasting.
Atmospheric pressure dyeing method can also apply this additive, and its temperature is mostly low, suitable for some light-colored or special needs fabrics. Although the flame retardant effect may be slightly inferior, if the process is properly formulated, the flame retardant performance can still meet the relevant standards. Dyeing and flame retardant go hand in hand, saving time and effort.
Roll dyeing method, first with dye liquid and flame retardant additive in aqueous solution, co-bath the polyester fabric, and then press it to make it evenly penetrate, and then warm bake and shape. The method is suitable for continuous treatment of large-scale and The flame retardant component is effectively combined with the polyester fiber, and it will last for a long time.
The dip-dyeing method is also a common process. The fabric is placed in a dyeing bath containing dyes and flame retardant additives, and it is heated and stirred for a long time to fully absorb the additives into the fiber structure. After setting and reinforcing, the flame retardant performance is firm.
All methods require attention to the coordination of dyeing temperature, additive concentration, pH value and dyeing bath time to maximize the flame retardant effect of Dye Bath Polyester Durable Flame Retardant. And the process conditions must be adjusted according to different polyester product specifications and end uses to give the polyester fabric excellent and durable flame retardant properties. Only in this way can we practice the industrial concept of green environmental protection, safety and durability, which is widely used in various fields such as clothing, home textiles, and industrial supplies.

Does Dye Bath Polyester Durable Flame Retardant affect fabric feel and color?
The application of polyester durable flame retardant in the dyeing bath can make the fabric have the ability to be flame retardant, but it has an impact on the feel and color of the fabric. The texture of polyester is slippery, but durable flame retardant is added, and it needs to go through high temperature, high pressure and chemical reaction to make the flame retardant components penetrate into the fiber. During this process, the fabric feels slightly different, more stiff and less natural and smooth; or if it is not handled properly, the feel may be coarse, which affects the comfort of wearing. Flame retardant molecules adhere to the surface of the fiber, or are embedded inside, thus changing the original appearance of the fabric. Different flame retardants have different degrees of influence. If the process is improved, this effect may be minimized, but in the end it will not be affected at all.
As for the color change, the color of dyed polyester is also easily affected after more than flame retardant treatment. Some components in the flame retardant reaction are easy to chemically react with the dye, or cover the dyeing check point on the surface of the fiber. If the flame retardant and the dye are not compatible, the color will be reduced, the brightness will decrease, or the color will change; or the dyeing will be uneven, resulting in mottles, and it is difficult to maintain a unified color. Moreover, some flame retardants have their own color, which can be slightly cloudy; even after coloring, it is difficult to hide their true color. Flame retardant is applied before dyeing, or flame retardant after dyeing, and the effect varies depending on the process. Designers and engineers weigh the pros and cons with experience, so as to ensure not only the need for flame retardancy, but also the beauty of product feel and color.
Then carefully design the dyeing bath formula, and select excellent additives, adjust the treatment period and temperature and humidity, which can slightly reduce the loss of feel and color. High-end products pay special attention to details. Manufacturers mostly use process optimization, raw material selection, and post-finishing methods to ensure that the fabric feels the same as before, and the color is still bright. Even so, the application of flame retardant will not be completely damaged by both, which is an indispensable part of the progress of product engineering. In summary, in order to obtain durable flame retardant and take into account the feel and color, it is necessary to take into account the raw materials, process, equipment and management in order to achieve excellent fabrics.

How to use and how much Dye Bath Polyester Durable Flame Retardant?
Dye Bath Polyester Durable Flame Retardant is used in polyester fiber dyeing baths to give it durable flame retardant properties. Its usage and dosage must be adjusted according to the fiber properties, dyeing bath composition and process requirements. To make the flame retardant effect full, first pretreat the polyester fabric to make it clean and free of impurities, so as to facilitate the uniform penetration of the subsequent agent. Next, add flame retardant in proportion to the dyeing bath. It is generally recommended to add 20 to 30 grams of flame retardant per liter of water. The specific amount depends on the flame retardant grade required and the thickness of the fabric. If higher flame retardant standards are required, it is appropriate to increase the dosage moderately, but not exceed the amount, so as not to affect the dyeing and feel.
When preparing the dyeing bath, first dissolve the flame retardant in warm water, mix well and then slowly add it to the main dyeing bath. Restart the stirring device to make the agent and the fiber evenly contact. The dyeing bath temperature should be 100 degrees, and the dyeing cycle is about 60 to 90 minutes. During this period, maintain a constant temperature and stirring. If used in a high-temperature and high-pressure dyeing machine, the operating temperature can be slightly higher, but do not suddenly rise or drop to prevent fiber damage. After the dyeing process is completed, the cloth surface must be rinsed with warm water to remove the residual agent, and then neutralized to return the fabric to neutral.
When flame retardants and dyes are used together, the compatibility is very high. It is advisable to choose a flame retardant with good dispersion to prevent uneven dyeing. If the finished product is heat-shaped and pressed in the future, the flame retardant performance can be further improved. When storing flame retardants, keep them away from moisture in the sun, clean and dry appliances, and close them tightly. I suggest regular testing of flame retardant effect to ensure constant quality. Discarded sewage must be recycled to ensure standards, and be careful to prevent pollution of the environment.
