Condensates derived from dialkyl ethers of dimethylolurea have been applied to wool fabrio with a view to rendering it unshrinkable. Although the lower ethers are ineffective for this purpose, the condensate from the di‐ n ‐butyl ether makes fabric unshrinkable with a deposit of less than 10%. Fabric treated with this condensate possesses a greatly improved resistance to abrasion, and yarn an increased tensile strength. It is considered that resins derived from these ethers function by a “spot‐welding” mechanism, as do the melamine resins and anhydrooarboxyglycine. We wish to thank Messrs.
