Preparation Method
FR Mflam THPC is prepared by using trimethylolphosphine (THPC) as the main raw material, supplemented by sodium hydroxide solution to adjust the alkalinity, dissolve THPC in an appropriate amount of water, stir at an isothermal speed, and add sodium hydroxide slowly to ensure complete reaction. Continue to use inorganic or organic polyphosphate as a stabilizer, and add suitable aldehyde co-reaction to reconcile the molecular structure. The process is carried out at room temperature or light temperature conditions. The main reaction is that THPC forms a phosphorus-carbon bond with cellulose hydroxyl groups, activates aldehyde, enhances the binding, and obtains a flame retardant effect. The catalytic mechanism depends on the synergy of sodium hydroxide and aldehyde to help THPC ionization, promote its uniform bonding on the fiber surface, and improve the flame retardant performance without damaging the fiber essence. The finished product is washed and dried, which is FR Mflam THPC, which is used for flame retardancy of cotton fabrics.
Chemical Reactions & Modifications
Mflam THPC, a phosphorus-based flame retardant, is specially used for the modification of cotton fabrics. Its chemical essence is tetrahydroxymethylphosphonate chloride. In contact with cotton fibers, the functional group reaction of phosphorus and nitrogen can form covalent bonds in the fibers. Initially, cotton weaving is impregnated with Mflam THPC solution, and then treated with ammonia to polymerize it. The structure generated by the reaction gives the fiber the characteristic of flame retardancy. Phosphorus and nitrogen are used together to promote carbonization in case of fire, reduce the precipitation of flammable gases, and greatly increase the fire protection efficiency. After modification, the cotton fabric has a tough structure, retained the feel, lasting flame retardant effect, and is not easy to fade after washing. This chemical reaction method breaks through the short-term effect of traditional surface coating and becomes intrinsically flame retardant. It is an effective way to improve safety performance in the textile industry.

What are the main flame retardant ingredients of FR Mflam THPC for Cotton?
FR Mflam THPC is a good solution to the flammable problem of cotton fabrics commonly used in the textile industry today. It is based on cotton, so that it adheres to the film layer and removes the fire. Its main medicinal substance is called tetrahydroxymethylphosphate, which is simply THPC by ancient and modern scholars. Or doubting its chemical nature, observe its formula as [ (CH 2O OH) P] Cl, which is an organic salt combined with phosphate and multi-oxime base, which is beneficial to neutralize the ear with chloride. Because it is easily soluble in water, it is immersed in cotton and cured with the characteristics of phosphorus, which can endow the fiber with flame retardant properties.
Ammonium tetrahydroxymethylphosphate is traced back to the category of organophosphorus flame retardants. Its properties are stable, and it is affinity with fibers. It enters the wood three points, so that the surface or the depth of the fibers are shaded. In case of fire, it decomposes, releasing acidic phosphorus compounds, causing rapid carbonization of fibers, and has the effect of suppressing flames and avoiding danger. Its flame retardant principle is that one is chemically endothermic, the other is to isolate oxygen, and the third is to form carbon on the surface, thus eliminating the cause of combustion. Since the 19th century, Bachelor has used this formula to form a variety of commodities. FR Mflam THPC is one of its popular and popular in the textile industry.
is a flame retardant used in cotton fabrics, with tetrahydroxymethylphosphate as the backbone. Others may be supplemented by additives, but the main medicine is not easier. The way of application, either by dipping, or by dyeing, is dried and solidified, and the film is formed on the surface and interior of the cotton, which does not change the quality, but also has to be safe and sound. The invention of this thing is a great test in the way of fire prevention, which is beneficial to the workshop and the well-being of all beings. Therefore, FR Mflam THPC is the main flame retardant component of cotton cloth, which is tetrahydroxymethylammonium phosphate.

What is the method and process of using FR Mflam THPC for Cotton?
The method of treating cotton by FR Mflam THPC must be carried out according to the rules in order to achieve its effect. At the beginning, if you want to treat cotton silk, you should first clean its dust and wash it frequently with water to remove all impurities and make the inside and outside pure. When it is clean, take the solution of FR Mflam THPC and mix it with water. The proportion is according to the factory regulations. Usually take the solution and water to mix one to ten or slightly more, and stir well. Next, soak the pure cotton in the prepared liquid, and the depth is not left, and the remaining 30 to 50 minutes allow the liquid to soak through the gap of the fibers. If you want the fire protection effect to be more obvious, you can adjust the dissolution ratio according to the cloth.
After the soaking is completed, the cotton weaving is taken out, and the residual liquid is slightly twisted to remove, but it cannot be squeezed out, leaving eight parts wet. Next, it must be neutralized with an alkali solution containing ammonia or sodium carbonate to form a fire-proof agent in the fibers of the cotton. At this time, the concentration of the alkali and the time of neutralization should be carefully selected to avoid damage to the fabric. After neutralization, rinse with water to wash out the remaining liquid, so that the cotton looks white. Then, put the cotton in the drying room, the temperature is 60 to 80 degrees Celsius, and gradually bake for two to three times, so that it can dry. Do not rush to prevent the fabric from shrinking or discoloring.
According to the outline, the principle of FR Mflam THPC in the treatment of cotton lies in the penetration of the liquid medicine, the neutralization of the lye, and the washing and drying of the water, such as several steps, layer after layer. Every time there is a change in new varieties or regulations, the sample should be tested first, and the dosage and process should be determined, and then it will be implemented on a large scale to avoid loss of interests. This method has the meaning of the ancients' fine-tuning of materials, and the ingenuity of modern people's scientific formulations can be used to make cotton silk non-flammable in the face of fire. It can be widely used for clothing, quilts, and curtains to benefit people's livelihood. If the "Technical Record" is like this, those who are well versed can follow the rules and do it

Does FR Mflam THPC for Cotton affect the feel and color of cotton fabrics?
FR Mflam THPC is a commonly used flame retardant, specially used in cotton fiber fabrics. Its chemical name is Tetrakis (hydroxymethyl) phosphonium chloride. It is used to treat cotton fabrics, which can significantly improve their flame retardant properties. However, the physical properties are also easier. It should be noted that flame retardant finishing involves many chemical reactions and extends to the inside of the fiber, so it may inevitably affect the feel and color of the fabric. Here are the details as follows. A brief explanation is given:
At the beginning, the change in feel is caused by the reaction of THPC molecules with cotton fiber hydroxyl groups to form a insoluble polymer structure to improve the fiber's resistance to flame. After this change, the softness and smoothness between the fibers are reduced, and when the hand touches, it may feel slightly sluggish and the softness is damaged. And because the pores of the fabric are filled with flame retardants, both breathability and drape may be damaged. However, it is suitable for soft finishing, which can make up for the lack of feel.
In terms of color, the cotton is white, but after flame retardant treatment, the color may be dim and the luster is slightly reduced. This edge THPC reacts with the fiber, or the flame retardant is slightly yellow, resulting in a slight yellowing of the fabric. If the fabric is originally dyed with bright pigments, it is more likely to show color distortion and reduced saturation. High concentration treatment, the more discolored; low dose, the lighter the color change. Therefore, flame retardant finishing must be coordinated with the dyeing process in order to balance function and beauty.
In addition, if the treatment is uneven, it is easy to cause the color difference of the fabric; if the finishing process is fine and the operation is proper, the adverse effects of color change and feel can still be suppressed. Modern technology has been improved many times, supplemented by smoothing agents, color fastness enhancers, etc., which not only increase the flame retardant effect, but also modify the fabric properties, and strive for profit and loss.
All in all, cotton fabrics have been flame retardant finishing by FR Mflam THPC, and the feel and color are more or less affected. However, through scientific process adjustment, it can still be ideal. If you want to combine flame retardancy and beauty, you must put technology first, carefully select materials, and take into account the use of fabrics, but you can only get the best.
