Textiles treated with hyperbranched polyethyleneimine derivatives for odor control properties

A process of treating a textile substrate, said process comprising:

• (a) providing a synthetic-containing textile substrate;
• (b) providing a dispersion comprising a hyperbranched polyethyleneimine derivative and a cross-linking agent, said hyperbranched polyethyleneimine derivative being of the formula:
• (R)x−h-PEI−(A)y
• where R is a non-hyperbranched hydrocarbon group, said hydrocarbon group having at least one linear portion, said linear portion having between 5 and 30 carbon atoms;
• where x is a number from 1 to 10,000;
• where h-PEI is a hyperbranched polyethyleneimine;
• where A is an organic compound having between 1 to 4;
• where y is a number from 0 to 500;
• and wherein R is present in an amount of between about 0.1% and about 20% by weight of said hyperbranched polyethyleneimine derivative, said dispersion containing said hyperbranched polyethylene derivative being produced by:
• (i) providing said hyperbranched polyethyleneimine derivative, a solubilizing agent, and water, said water having a temperature at least equal to the melting point of said hyperbranched polyethyleneimine derivative;
• and
• (ii) subjecting said hyperbranched polyethyleneimine derivative, said solubilizing agent, and said water to high speed and high shear agitation;
• (c) applying said dispersion to said textile substrate;
• and
• (d) drying said textile substrate.

A treated textile substrate, said treated textile fabric comprises:

• (a) a synthetic-containing textile substrate;
• and
• (b) a treatment applied to at least one side of said textile substrate, said treatment comprising:
• a hyperbranched polyethyleneimine derivative of the formula:
• (R)x−h-PEI−(A)y
• where R is a non-hyperbranched hydrocarbon group, said hydrocarbon group having at least one linear portion, said linear portion having between 5 and 30 carbon atoms;
• where x is a number from 1 to 10,000;
• where A is an organic compound having from 1 to 4 carbon atoms;
• where y is a number from 0 to 500;
• where h-PEI is a hyperbranched polyethyleneimine;
• and wherein R is present in an amount of between about 20% and about 80% by weight of said hyperbranched polyethyleneimine derivative.
