Document Type and Number:
Japanese Patent JPH0643478
Kind Code:
B2
Abstract:
Synthetic polyamide textile substrate having deposited thereon a modified polymeric sulfonated phenol-formaldehyde condensation product comprising one (a) in which 10 to 25% of the polymer units contain SO3 <(-)> radicals and about 90 to 75% of the polymer units contain sulfone radicals and (b) in which a portion of the free hydroxyl groups thereof has been acylated or etherified, the number of said hydroxyl groups which has been acylated or etherified being sufficient to inhibit yellowing of said condensation product but insufficient to reduce materially the capacity of said condensation product to impart stain resistance to said synthetic polyamide textile substrate.
