Definitions

• the present invention relates to the treatment of textile materials so as to render the same crease resistant and wrinkle resistant, and more particularly to the treatment of cellulose materials to impart crease resistant and wrinkle resistant properties to the same while maintaining the strength of the material.
• the textile material is coated with cellulose ethers of different kinds.
• alkyl cellulose products such as methyl cellulose or methyl ethyl cellulose, which preferably should be completely etherified because otherwise they are not sufiiciently water-soluble, are not suitable because they can not prevent the stiffness and brittleness of a textile mate rial caused by the deposition of synthetic resins.
• the present invention provides a method of providing crease resistance to cellulose material by a procedure which avoids all of the above and other enumerated disadvantages of the prior art.

• the treating of the textile material may be carried out by spraying the same with the aqueous liquor, but is preferably accomplished by immersing thetextile material in the liquor.

• the method of the present invention makes it possible to improve textile material of the cellulose type with respect to the crease resistance thereof while retaining the properties of strength and also while giving to the textile material a good feel.
• the method of the present invention is particularly advantageous in that the crease resistance which is imparted to the textiles remains even after laundering.
• This is achieved in accordance with the present inventionby the use of the cellulose mixed ether, that is the alkoxy cellulose which contains free hydroxyl groups in the cellulose molecule, these free hydroxyl Such" groups reacting with and cross linking the resin-forming substance, for example the dimethylol urea.
• the cellulose mixed ether also has the advantage'of a good water solubility and the possibility of producing stable, non-flocculating solutions.
