Method of treating textile materials

Claim 2

A process of treating textile materials which comprises the steps of: (a) applying a first finishing agent-containing composition to a textile material; (b) thereafter coating said textile material containing said first composition with a second composition in the form of a foam, said second composition being coated over said first finishing agent-containing composition prior to fixation of said first composition; (c) collapsing the subsequently applied foamed composition so as to force said first finishing agent-containing composition into said textile; and (d) thereafter fixing said finishing agent to said textile material.

Claim 3

The process according to claim 1 wherein said first finishing agent-containing composition is in a liquid form and is applied to the textile material in the form of a foam and wherein said foam is collapsed prior to application of said later applied second foam composition, said textile material having approximately 10 to 65% liquid by weight prior to application of said second foam composition.

Claim 4

The process according to claim 1 wherein said finishing agent is selected from the group consisting of coloring materials, durable press agents, water repellent agents, soil release agents, softeners, weighting agents and fire retardant agents.

Claim 5

The process according to claim 3 wherein said finishing agent in said first composition comprises a coloring material.

Claim 6

The process according to claim 1 wherein said collapsing step causes the foamed composition to penetrate substantially the entire thickness of said textile material.

Claim 7

The process according to claim 2 wherein said second composition includes therein a finishing agent.

Claim 8

The process according to claim 2 wherein both said first and second compositions are foamed compositions applied to said textile material by knife-coating said compositions onto said textile material.

Claim 9

The process according to claim 2 wherein application of said first finishing agent composition includes applying a foamed composition including therein a coloring material to be applied onto the textile material in a pre-selected pattern.

Claim 10

The process according to claim 1 wherein application of said first finishing agent containing composition comprises applying a powdered finishing agent onto the textile material.

Claim 11

The process according to claim 2 wherein collapse of said second foam composition is achieved by application of a vacuum, padding or a combination of vacuum and padding.

Claim 12

The process according to claim 1 wherein said second foamed composition includes an aqueous finishing agent and is prepared by forming a mixture comprised of liquid medium, finishing agent and foaming agent, and foaming the mixture to a blow ratio in the range of from about 2:1 to about 20:1 to produce a foam having a foam density in the range of from about 0.5 gm/cc to about 0.05 gm/cc.

Claim 13

The process according to claim 1 wherein said first finishing agent is applied as a foamed printing composition by means of a rotary screen printer or intaglio printing cylinder.

Claim 14

The process according to claim 1 wherein said first finishing agent is applied as a foamed printing composition to a pile substrate.

Claim 15

A process for dyeing textile materials which comprises the steps of: (a) preparing a foamed dye containing composition which includes a reactive material therein; (b) applying said foamed dye containing composition to said textile material; (c) collapsing said foamed dye containing composition; (d) preparing a second foamed composition containing therein a material suitable to interact with said reactive material in said foamed dye containing composition; (e) coating said textile material containing said foamed dye containing composition with said second foamed composition, said second composition being coated over said foamed dye containing composition prior to fixation of said foamed dye containing composition; (f) collapsing said second foamed composition so as to achieve penetration of said dye into said textile material; (g) allowing said reactive material in said foamed dye containing material to interact with the material in said second foamed composition; and (h) thereafter drying and fixing the dye in said textile material.

Claim 16

A process for dyeing textile materials which comprises the steps of: (a) preparing a foamed dye containing composition which includes a reactive material therein; (b) applying said foamed dye containing composition to said textile material; (c) collapsing said foamed dye containing composition; (d) preparing a second foamed composition containing therein a material suitable to interact with said reactive material in said foamed dye containing composition; (e) coating said textile material containing said foamed dye containing composition with said second foamed composition, said second composition being coated over said foamed dye containing composition prior to fixation of said foamed dye containing composition; (f) collapsing said second foamed composition so as to achieve penetration of said dye into said textile material; (g) allowing said reactive material in said foamed dye containing material to interact with the material in said second foamed composition; and (h) thereafter drying and fixing the dye in said textile material.

Claim 17

The process according to claim 14 wherein said foamed dye containing composition includes a reactive dye material therein and is applied to a cellulosic fabric and said second foamed composition is alkaline so as to develop said reactive dye material.

Claim 18

A process for dyeing textile materials which comprises the steps of: (a) preparing a dye containing composition which includes a reactive material therein; (b) applying said dye containing composition to said textile material; (c) preparing a foamed composition containing therein a material suitable to interact with said reactive material in said dye containing composition; (d) coating said textile material containing said dye containing composition with said foamed composition, said foamed composition being coated over said dye containing composition prior to fixation of said dye containing composition; (e) collapsing said foamed composition so as to achieve penetration of said dye into said textile material; (f) allowing said reactive material in said dye containing material to interact with the material in said foamed composition; and (g) thereafter drying and fixing the dye in said textile material.

Claim 19

A process for dyeing textile materials which comprises the steps of: (a) preparing a dye containing composition which includes a reactive material therein; (b) applying said dye containing composition to said textile material; (c) preparing a foamed composition containing therein a material suitable to interact with said reactive material in said dye containing composition; (d) coating said textile material containing said dye containing composition with said foamed composition, said foamed composition being coated over said dye containing composition prior to fixation of said dye containing composition; (e) collapsing said foamed composition so as to achieve penetration of said dye into said textile material; (f) allowing said reactive material in said dye containing material to interact with the material in said foamed composition; and (g) thereafter drying and fixing the dye in said textile material.

Claim 20

The process according to claim 16 wherein said dye containing composition includes a reactive dye material therein and is applied to a cellulosic fabric and said foamed composition is alkaline so as to develop said reactive dye material.
