Abstract
Excellent stain block property, WAQE resistance and yellowing resistance are imparted to a textile by a method of preparing a treated textile has the steps of (1) preparing a treatment liquid comprising a stain blocking agent and a sulfated castor oil and having pH of at most 7, (2) applying the treatment liquid to the textile, (3) treating the textile with steam, and (4) washing the textile with water and dehydrating the textile.

A method of preparing a treated textile, comprising steps of:
- (1) mixing a stain blocking agent, a sulfated castor oil and optionally water to prepare a treatment liquid comprising the stain blocking agent and the sulfated castor oil and having pH of at most 7,
- (2) applying the treatment liquid to the textile,
- (3) treating the textile with steam, and
- (4) washing the textile with water and dehydrating the textile,
- wherein the stain blocking agent is selected from the group consisting of a phenol-formaldehyde condensate, an acrylic polymer and a mixture of a phenol/formaldehyde condensate and acrylic polymer.
A treatment liquid for use in a method of preparing a treated textile, the method comprising steps of:

- (2) applying the treatment liquid to the textile,
- (3) treating the textile with steam, and
- (4) washing the textile with water and dehydrating the textile where in the treatment liquid comprises a stain blocking agent, a sulfated castor oil, and optionally, water and having a pH of at most 7, and,
- wherein the stain blocking agent is selected from the group consisting of a phenol-formaldehyde condensate, an acrylic polymer and a mixture of a phenol/formaldehyde condensate and acrylic polymer.
A method of preparing a treated textile, comprising steps of:
- (1) mixing a stain blocking agent, a sulfated castor oil having an unsaturated bond and optionally water to prepare a treatment liquid comprising the stain blocking agent and the sulfated castor oil having an unsaturated bond and having pH of at most 7,
- (2) applying the treatment liquid to the textile,
- (3) treating the textile with steam, and
- (4) washing the textile with water and dehydrating the textile,
- wherein the stain blocking agent is selected from the group consisting of a phenol-formaldehyde condensate, an acrylic polymer and a mixture of a phenol/formaldehyde condensate and acrylic polymer.
