Benefits of technology

[0015] The composition may further include one or more additives such as known polyols, viscosity modifiers, non-ionic surfactants to reduce surface tension, drying preventing agents, penetration acc

Problems solved by technology

A simple application of a dye solution onto cotton or polyester fabrics usually fails to durably dye the fabric, and the dye is simply washed out upon laundering of the fabric.
However, these dyes are generally not lightfast or washfast on polyester textiles.
Covalent attachment of dyes to a cationic polymer on a laboratory scale is also known, but it is not economically feasible to scale up this reaction for commercial production.
As there is no universal dye for textiles, a printer cartridge containing a textile ink composition for printing on one type of fabric cannot be used for printing on another type of fabric.

example 1

[0034] A series of textile inks was prepared by mixing a cationically charged metal oxide with a number of dyes. The cationically charged metal oxide that was used in the example was a 50 weight percent aqueous solution of aluminum chlorohydrol obtained from Reheis. The dyes used in the example were Carminic Acid, Alizarin Red S, Acid Blue 45, Acid Green 41, Mordant Yellow 12, Hematoxylin, Mordant Blue 9, Chromoxane Cyanine R, Calcon Carboxylic Acid, Plasmocorinth B, Pyrocatechol, Acid Alizarin Violet N and Alizarin Yellow GG, obtained from Aldrich Chemical Corporation.

[0035] The textile ink compositions were formed by adding 25 microliters of the aluminum chlorohydrol solution to 1 ml of a 20 mM solution of each dye at room temperature, and the mixture was stirred vigorously for 30 minutes.

[0036] Each textile ink composition was then spotted onto separate cotton and polyester textile fabrics by applying a 10-20 microliter drop of the ink composition onto the fabric surface. The p...

example 2

[0039] Textile ink compositions were prepared as described in example 1 and were spotted onto cotton and polyester fabrics. The fabrics were then washed in a domestic washing machine on the harshest washing cycle, using the recommended dosage of a domestic laundry detergent (TIDE® from Procter & Gamble, USA) and hot water (about 90 degrees Celsius) for up to 30 minutes. The color intensities and washfast values were calculated as described above, and the results that were obtained were similar to those in example 1. A skilled person will understand that this is a fairly harsh washfast test for any printed ink, and the results of this test are thus a good indication that the ink compositions are able to durably dye different fabrics.

example 3

[0040] Textile ink compositions prepared according to example 1 were spotted onto a silk charmeuse fabric and allowed to dry. The washfastness was tested using the AATCC Washfast Test Method 61-2003 described above, and the fabric colors prior to and after the wash test were analyzed qualitatively (results not shown). The ink compositions were shown to dye silk fabric equally well.

[0041] From the above examples, it can be seen that the applicant has utilized commercially available metal oxide oligomers and commercially available dyes to develop durable and washfast textile ink compositions that work equally well on silk, cotton and polyester fabrics.

[0042] In addition to being able to durably dye more than one type of fabric, the ink compositions of the present invention are able to incorporate more dye than many other inks, are soluble and are therefore readily incorporated into inkjet inks, and do not have lightfast issues that are associated with other inks.

Abstract

A textile ink composition and a method of manufacturing a textile ink composition are disclosed. The textile ink composition is formed from a cationically charged metal oxide and a dye, and is capable of durably dyeing different types of fabric. The cationically charged metal oxide is typically an oligomer, such as an alumina oligomer. A suitable alumina oligomer is aluminum chlorohydrate. Typical dyes have anthraquinone, catechol, hydroxyazo or salicylic acid groups or are mordant dyes, such as Carminic Acid, Alizarin Red, Acid Blue 45, Acid Green 41, Hematoxylin, Chromoxane Cyanine R, Calconcarboxylic Acid, Plasmocorinth B, Pyrocatechol, Acid Alizarin Violet N, Alizarin Yellow GG, Mordant Yellow 12 and Mordant Blue 9.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to textile ink compositions that are capable of durably dyeing two or more types of fabric. A method of preparing such a composition is also disclosed. [0002] A simple application of a dye solution onto cotton or polyester fabrics usually fails to durably dye the fabric, and the dye is simply washed out upon laundering of the fabric. This is due to the absence of any specific interaction mechanisms or covalent attachment between the fibers and the dye molecules. [0003] Only a few commercially available dyes can be used to form washfast textile inks in this manner, and these inks are generally specific to only one type of fabric. For example, fiber reactive dyes are able to durably dye cotton, but not polyester. [0004] Most dyes require some form of pre- or post-dye treatment of the fabric in order to durably dye the fabric. Thus, developed dyes require the fabric to be first treated with a direct dye, then treated with...
