Aqueous dyeing composition and process for synthetic substrates

Abstract

A composition of matter for aqueous dyeing of synthetic substrates and a method of aqueous dyeing of a synthetic substrate.

What is claimed is: 
     
         1 . A composition of matter for solution dyeing of synthetic substrates, said composition comprising:
 i. water, and for every 1200 milliliters of water,   ii. 500 to 725 milliliters of propylene glycol;   iii. 167 to 450 milliliters of surfactant;   iv. 0 to 250 milliliters of pine oil;   v. 0 to 2 50 milliliters of acetic acid;   vi. 0 to 250 milliliters of limonene;   vii. 0 to 350 milliliters of naphthalene hydrocarbon,   viii. 0 to 250 milliliters of dye penetrant, and   ix. a predetermined amount of dye.   
     
     
         2 . A method of aqueous dyeing of a synthetic substrate, said method comprising contacting said synthetic substrate with a composition of matter as claimed in  claim 1  for a predetermined period of time at a predetermined temperature and pressure until a desired color and color intensity of said synthetic substrate is achieved.
