The invention discloses a fabric penetrating agent facilitating even dyeing. The fabric penetrating agent facilitating even dyeing is prepared from the following components in parts by weight: 5-12 parts of methanol polyoxyethylene ether, 3-10 parts of p-toluenesulfonic acid, 5-15 parts of maleic anhydride, 6-12 parts of sodium pyrosulfite, 10-24 parts of para-toluene, 8-20 parts of esters, 10-25 parts of polyvinyl alcohol, 5-12 parts of polyethylene glycol, 3-18 parts of polyvidone and 75-105 parts of water. According to the mode, the color of the dyed fabric is uniform and full by the fabric penetrating agent facilitating even dyeing, the dyed fabric feels soft and plump, the fabric penetrating agent can protect the fabric, the capillary effect is full, and the fabric is prevented from yellowing.
