Formaldehyde is one volatile compound, usually used in textile for crease-resist and shrink-resist compound agent, which also used as dye-fixing agent, water-proofing agent, softening agent and binding agent on production, widely used. Formaldehyde also is one irritation compound, easy caused skin allergy reaction and body airway etc illness. Fewer formaldehyde will have irritation effect on eyes / skin and mucosa, excess formaldehyde will make the mucosa and airway have heavy inflammation, also can cause dermitis.
Japan 's clothing eco standard have the clear limitation on the percentage of formaldehyde.
Chinese national textile product basic safe technical specification (GB/T18401-2003) request: infant and child products (A class)'s formaldehyde content cannot over 20mg/kg, directly touched skin product (B class)'s formaldehyde content cannot over 75mg/kg, non-directly touched skin product (C class)'s formaldehyde content cannot over 300mg/kg.
During textile processing, formaldehyde mainly coming from below 3 aspect:
（1）Creasing management: cross-linking agent with formaldehyde still widely used on crease-resist/ anti-wrinkle and noniron arrangement, if using inappropriately, which will cause it's concentration over allowed range.
（2）Increase color fastness: cheaper formaldehyde agent usually used on direct dyeing, at times used on activity dyeing for after arrangement. According to the recipe, on A class products, its content is easy exceed the limit of 20mg/kg, even exceed 75 mg/kg limitation of B class products. Nowadays there are cationic auxiliary with fewer or non formaldehyde, such as tin A/B type.
（3）Pigment printing: high quality 's cross-linking formaldehyde widely used on pigment printing craft, which means even used carefully , it scarcely possible conform 75mg/kg limitation. Now there have cross-linking agent with lower formaldehyde, that is to say, in the agent with urea and formaldehyde, used together will reach the non-formaldehyde pigment printing target.
Usually permanent crease-resist and anti-shrink arrangement agent used textile easy to test exceed standard formaldehyde existing.

How does Formaldehyde harm the environment?
Formaldehyde can harm the environment by contributing to air pollution when released from industrial sources. It can also contaminate water sources when it is discharged into water bodies, affecting aquatic life. Additionally, formaldehyde can react with other pollutants in the atmosphere to form harmful secondary pollutants like ozone.
What are the dangers of Urea-Formaldehyde resin?
Urea-formaldehyde resin can emit formaldehyde gas, which is a known carcinogen and can cause respiratory irritation. Prolonged exposure to formaldehyde can lead to health issues such as headaches, dizziness, and allergic reactions. It is important to use urea-formaldehyde products in well-ventilated areas to minimize the risk of harmful effects.
What type of matter is formaldehyde correctly classified?
Formaldehyde, HCHO, is an example of an aldehyde (or carbonyl compounds)
Which two atoms in this formaldehyde molecule?
There are three elements present in formaldehyde. Namely, they are carbon, hydrogen and oxygen.
What is the melting point of formaldehyde?
The melting point of formaldehyde is approximately -80.1 degrees Celsius (-112.2 degrees Fahrenheit). At this temperature, formaldehyde transitions from a solid to a liquid state. In its common form as a gas, formaldehyde is typically encountered at room temperature, but it can be stored as a solution in water or as solid paraformaldehyde.
What does formaldehyde smell like in clothing?
Formaldehyde in clothing has a strong, pungent odor that is often described as sharp, chemical-like, or similar to a mix of vinegar and paint thinner.
How can formaldehyde be effectively removed from clothing?
Formaldehyde can be effectively removed from clothing by washing the clothes with a mixture of water and baking soda, or by soaking them in a solution of vinegar and water. Additionally, hanging the clothes outside in fresh air and sunlight can help to naturally dissipate the formaldehyde.

What Harmful Effects of Excessive Formaldehyde in Textile?
The function of formaldehyde in textile is created a cross-linking agent with synthetic resin, will formed one layer of protection on the sample, which have iron proof, shrink-proof, wrinkle-free, soil release and other functions. However, excessive formaldehyde is harm to human health. Formaldehyde have a strong stimulating effect to skin and eyes mucous membranes, if there is much more formaldehyde content in textiles, the formaldehyde will release with the process of wearing, through the skin and the respiratory tract to hurt human, it is especially to stimulate the infant's skin and the respiratory tract. When children wearing excessive formaldehyde clothing, the symptoms are mild tears, cough, contact dermatitis, fingers and nails sore, in the most severe cases, will feels insomnia, dizziness, headache and so on. Long time wearing formaldehyde content clothing, inhalation low formaldehyde content also can cause chronic respiratory disease, conjunctivitis, sphagitis, asthma, bronchitis, even cancer.Following are the GB18401 National Fundamental Safety Technical Standard For Textiles requirement about formaldehyde content limited:Products for babies(A): formaldehyde content 20mg/kg;Products with direct contact to skin(B): formaldehyde content75mg/kgProducts without direct contact to skin(c): formaldehyde content300mg/kgConsumer guide:1) When purchasing textile clothing, pls choose regular commercial enterprise clothing, and pay attention to the logo content to make sure of satisfactory goods.2) Washing the new clothing before wearing, which will makes lower the power of hydrogen and color fade effect to human body.3) When buying textile clothing, pls choose light color clothing, dark color clothing is easy to fade. For dark color product, we can use white color fabric to rub it, do not buy it once color fade, it is rejected product.4) Asking the formal institutions text report from the sellers when buying thing, you cannot buy it without text report.5) Especially buying iron-free garment and printing coating garment, it is better to ask if the garment have the fishily smell or peculiar smell, if have, do not buy it.

How do you manufacture formaline?
Formalin (which is what I suppose you are asking about) is another name for formaldahyde.Formaldehyde is produced industrially by the catalytic oxidation of methanol.See the "Sources and related links below"
What is formaldhyde?
Formaldehyde (IUPAC name methanal) is a chemical compound with the formula H2CO. Sources of formaldehyde in the home include building materials, smoking, household products, and the use of un-vented, fuel-burning appliances, like gas stoves or kerosene space heaters. Formaldehyde, by itself or in combination with other chemicals, serves a number of purposes in manufactured products. For example, it is used to add permanent-press qualities to clothing and draperies, as a component of glues and adhesives, and as a preservative in some paints and coating products.
Is Formaldehyde a protein?
No, formaldehyde is an example of an aldehyde, not protein.
What is formaldehyde-free mean?
Formaldehyde-free means that a product does not contain any formaldehyde or formaldehyde-releasing ingredients. Formaldehyde is a potentially harmful chemical often used in glues, resins, and other products. Choosing formaldehyde-free products can reduce exposure to this substance, which is known to cause irritation and other health concerns.
