1,3-Dimethylurea CAS 96-31-1: Core Raw Material for Formaldehyde-Free Textile Auxiliaries-title

As a professional 1,3-Dimethylurea manufacturer, HBGX Chemical has years of experience in supplying raw materials for textile auxiliaries. We mainly supply 1,3-Dimethylurea CAS 96-31-1 flakes, the core synthetic raw material for formaldehyde-free anti-wrinkle finishing agents and wrinkle-resistant fabric auxiliaries. With mature production technology and strict quality control system, our dimethylurea products fit the post-finishing processes of cotton, polyester-cotton and other fabrics. Finished textiles made with our materials can smoothly pass Oeko-Tex, GB 18401 and other domestic & international eco-textile standards. We supply bulk goods to printing & dyeing factories and textile auxiliary manufacturers all over the world.

Basic Physicochemical Index of 1,3-Dimethylurea CAS 96-31-1

We provide two mainstream grades of 1,3-Dimethylurea: 95% industrial grade and 98% high-purity grade. Both are off-white flake crystals with excellent solubility in water and alcohol, featuring stable chemical properties and long storage life without deterioration. 95% grade 1,3-Dimethylurea delivers outstanding cost performance for mass production of low-formaldehyde textile auxiliaries. The 98% high-purity dimethylurea contains extremely low impurities, specially formulated for high-end formaldehyde-free wrinkle-free finishing agents and infant textile auxiliary formulas. Moisture content is strictly controlled within 1.0%, with a stable melting point of 103~108°C. Each batch is delivered with complete COA test reports and MSDS safety data sheets with transparent traceable indicators, ideal for the synthesis of all kinds of textile auxiliary chemicals.

Working Principle of dimethylurea in textile wrinkle resistant finishing

Traditional wrinkle-free fabric auxiliaries commonly adopt crosslinking agents that release free formaldehyde during production and wearing, bringing environmental risks and skin irritation. 1,3-Dimethylurea is the key intermediate to solve this problem. Dimethylurea possesses superior formaldehyde capturing capacity. During fabric post-finishing, it reacts with free formaldehyde in the system to form stable, harmless compounds and drastically cut formaldehyde residue on textiles. Meanwhile, its molecules form moderate crosslinks with cotton fiber molecules to build a stable internal mesh structure in fabrics. Long-lasting wrinkle resistance can be achieved without high-formaldehyde crosslinkers, balancing soft hand feel and wearing safety. It is an indispensable core raw material for eco-friendly textile auxiliaries.

Main Fabric Types Suitable For textile auxiliary chemicals Formulation

1,3-Dimethylurea fits auxiliary formulas for most wrinkle-prone fabrics, covering mainstream textiles in printing and dyeing industries:

Pure cotton fabrics: Pure cotton shirts, bed linens and undergarments are prone to wrinkling. Finishing agents based on dimethylurea deliver durable wrinkle-free effects and meet eco standards for infant wear and close-fitting apparel.

Polyester-cotton blended fabrics: Poly-cotton cloth easily wrinkles and tends to feel stiff after treatment with conventional auxiliaries. Finishing agents formulated with 1,3-Dimethylurea balance anti-wrinkle performance and fabric softness, widely applied in workwear and home textile production.

Other cellulosic fabrics: Viscose, linen and similar textiles are also compatible, effectively avoiding failed export inspections caused by high formaldehyde levels, perfectly matching the production demands of foreign trade textile factories.

Global Environmental Standards Supported By Our 1,3-Dimethylurea

Export textiles and high-end domestic fabrics are subject to strict formaldehyde limit regulations. Our 1,3-Dimethylurea is produced in line with green chemical standards. Finished textile auxiliary chemicals manufactured from our raw materials easily pass two core eco standards:

Oeko-Tex Standard: Authoritative EU textile testing specification, suitable for garments and home textiles exported to Europe and America without risks of excessive formaldehyde residue.

GB 18401 National Standard: Mandatory domestic safety standard for textiles, classified into Category A for infant products, Category B for direct skin contact goods and Category C for non-contact textiles. Finishing agents produced with our dimethylurea fully comply with all categories. In addition, our products are certified by ISO9001 and ISO14001 and registered under EU REACH. Foreign trade textile auxiliary wholesalers will face no customs clearance issues related to environmental compliance.

FAQ About Sourcing 1,3-dimethylurea flake For Textile Factories

Q1: How to choose between 95% and 98% 1,3-dimethylurea flakes?

A: 95% grade 1,3-dimethylurea flake is cost-effective for regular industrial printing & dyeing and low-end home textile auxiliaries. The 98% high-purity dimethylurea is recommended for infant fabrics, high-end foreign trade garments and strict formaldehyde-free auxiliary formulas, with fewer impurities and higher passing rates for textile testing.

Q2: What packaging and bulk purchase policies do you offer?

A: Standard 25kg woven bags with inner moisture-proof PE liners. Custom 500kg / 1000kg bulk bags are available. Tiered discounts apply for bulk orders of 1,3-Dimethylurea. Long-term cooperative printing and dyeing factories and textile auxiliary manufacturers can apply for quarterly price lock.

Q3: Can I get samples? How long is the lead time?

A: Free 1kg and 5kg samples are available; buyers only cover shipping fees. Large stock of regular 1,3-dimethylurea flakes is kept in warehouse. Domestic orders ship within 3-5 working days, while all customs documents for export orders will be ready within 7 working days.

Q4: Do you supply other textile intermediates besides 1,3-Dimethylurea?

A: We provide a full range of chemical intermediates for one-stop procurement, including all kinds of PVC stabilizer intermediates and pharmaceutical synthesis raw materials, cutting procurement costs for factories sourcing multiple fine chemical raw materials.
