Definitions
- This disclosure relates to processes for pretreating fabrics. Specifically, this disclosure relates to pretreatment processes for natural fiber fabrics that may be used for dye sublimation ink printing.
- Printed fabrics are useful for several different products including, but not limited to, clothing, bedding, window treatments, signage, upholstery, etc. Printing onto fabrics allows for a variety of patterns and designs to be used on the fabric.
- dye sublimation inks are often used for printing on synthetic fabrics due to their ability to penetrate the fiber, their color vibrancy, their crock testing results, and their colorfastness to laundering.
- dye sublimation inks are not suitable for printing on natural fiber fabrics because the dyes penetrate and do not adhere to the natural fibers. This lack of adhesion can cause bleeding during laundering, a reduction in color density, a decrease in colorfastness to laundering, and a decrease in crock of the printed fabric.
- pretreatment compositions pretreated natural fiber fabrics, methods for preparing pretreatment compositions, and methods for pretreating natural fiber fabrics that can render fabrics suitable for dye sublimation ink printing by improving the adhesion of the ink to the natural fiber fabric.

- FIGS. 1 A-1D provide the various stages of pretreating fabric, according to some embodiments.
- pretreatment compositions pretreated natural fiber fabrics, methods for preparing pretreatment compositions, and methods for pretreating that can be applied to natural fiber fabrics to make the fabric suitable for dye sublimation ink printing.
- dye sublimation inks may adhere more easily to the natural fiber fabrics.
- pretreating natural fiber fabrics with a pretreatment composition described herein can improve properties such as crock, hand, colorfastness to laundering, adhesion, color density, etc. when printed with dye sublimation ink as compared to non-treated natural fiber fabrics printed with dye sublimation inks.
- Dye sublimation inks are sometimes used to print onto a film.
- This film can then be transferred to a natural fiber fabric using a heat press to create a printed natural fiber fabric.
- this method does not allow for a user to print onto the fabric. Additionally, this method is limited because only color images having 100% density can be transferred, the thickness of the film leads to poor hand (i.e., a subjective characteristic that includes smoothness, compressibility, and elasticity of the fabric), the tested colorfastness to laundering is poor, and it causes a reduction in the elasticity or elongation of the fabric.
- pretreatment compositions provided herein have been developed to coat natural fiber fabrics and improve the adhesion of colorants (e.g., dye sublimation ink) to the fabric.
- colorants e.g., dye sublimation ink
- These pretreatment compositions in addition to methods for pretreating disclosed herein, improve the adhesion of dye sublimation ink to the natural fiber fabric specifically because natural fiber fabrics are hydrophilic, whereas synthetic fibers are hydrophobic. The hydrophilicity of the natural fiber fabric impairs the ability of dye sublimation inks to adhere and absorb into the natural fibers.
- Pretreatment compositions and methods of pretreating provided herein can provide a synthetic, or polymeric coating on the surface of the natural fibers of a natural fiber fabric.
- This synthetic, polymeric coating dries onto the fibers of the fabric and conforms to the surface of the fabric. Further, the coating can in turn provide hydrophobic characteristics to the natural fiber fabric, increasing the affinity of the dye sublimation ink to the fabric. More specifically, the dye sublimation ink can adhere and absorb into the synthetic, polymeric coating of the pretreatment without penetrating the natural fibers of the natural fiber fabric.
- pretreating natural fiber fabrics can allow for a more permanent printed image, in contrast to a dye sublimation ink-printed image on a non-pretreated natural fiber that will penetrate the fibers and fail to withstand laundering, for example.
- pretreatment compositions provided herein can provide a coating that adheres to the natural fibers of the natural fiber fabric and also provides an ink-receptive coating for dye.
- pretreatment compositions provided herein. In particular, discussed below are: (1) pretreatment compositions; (2) methods of preparing pretreatment compositions; (3) methods of pretreating fabrics; and (4) pretreated fabrics.
- Pretreatment compositions may include a polymer, a coalescing agent, a surfactant, an antioxidant/ultraviolet light absorber, a humectant(s), a pH buffer(s), a biocide(s), and/or water.
- a pretreatment composition comprising each of these components can provide a coating that adheres to the natural fibers of the natural fiber fabric and also provides an ink-receptive coating for dye.
- the pretreatment compositions provided herein may be used with natural fiber fabric, synthetic fabric, or a fabric comprising a combination of natural and synthetic fibers. Note that the weight- percents provided with respect to each of these components refer to pretreatment compositions prior to pretreating fabric, unless stated otherwise.
- pretreatment compositions described herein may include a polymer composition.
- a polymer provides a component for the dyes to attach to during the printing process.

- Method 3 The amount of pretreatment added to each cotton substrate can be 0.1 g/in 2 .
- the pretreatment can be applied using a handheld sprayer onto a cotton t-shirt.
- the cotton t- shirt can be setup with a section of aluminum of the same size as the printed image inside the shirt and a plastic cut out of the print image outside to ensure that no pretreatment is applied outside the area where the print image will be transferred.
- the shirt can be slipped onto the bottom half of the heat press and the same aluminum substrate can be placed inside. This can ensure that the area covered with pretreatment will be the only area pressed.
- the shirt can be pressed for 325 F for 10 seconds.
- the pretreatment application of the pretreatment composition can be applied in an amount of 0.01-5 g/in 2 , 0.5 - 1.5 g/in 2 , or 0.1 g/in 2 and pressed at 200-400°F, 250-400°F, 300- 350°F, or 325°F for 1-60 seconds, 1-30 seconds, 1-20 seconds, or 10 seconds.
- a printed fabric s colorfastness determines its ability to retain its depth and shade throughout the life of the product, and in particular, throughout laundering of the product. Ideally, a printed image on a fabric can withstand the lifetime of the product without significantly compromising the quality (e.g., depth, shade) of the printed image.
- the colorfastness of a printed natural fiber fabric may be tested using Method 1, Method 2, and/or Method 3, described below.
- Method 1 Colorfastness to laundering may be tested by placing a printed fabric sample measuring 4.5 inches by 5.5 inches in a consumer washing machine and washed for 15 minutes with room temperature water and 0.5 g of Tide ® detergent per 0.5 L of water. A standard wash cycle was used (cotton/medium) with a standard spin cycle. (The sample was washed with 9-14 other printed fabric samples). The printed fabric sample was rinsed with 0.5 L water per sample for six minutes. The sample(s) was then spin-dried for five minutes and placed in an oven at 60°C until dry.
- Method 2 Colorfastness to laundering may be tested by placing a printed fabric sample measuring 9 inches by 5 inches was placed in a consumer washing machine and washed for 15 minutes with room temperature water and 0.5 g of Woolite ® Delicate detergent per 0.5 L of water. A standard wash cycle was used (cotton/medium) with a standard spin cycle. (The sample was washed with 4-7 other printed fabric samples). The printed fabric sample was rinsed with 0.5 L water per sample for six minutes. The sample(s) was then spin-dried for five minutes and hung to air dry.
- the washed and dried samples were analyzed using a Gretag spectrophotometer for optical density, L, a*, and b* values.
- the image was printed using a standard DOD inkjet printer (Mutoh 90 lx) using standard dye sublimation inks onto Wing Wing Hybrid transfer paper. The image was transferred at 385°F for 35 seconds.
- Method 3 Colorfastness to laundering may be tested by placing a printed fabric sample measuring 9 inches by 5 inches was placed in a consumer washing machine and washed for 15 minutes with room temperature water and 0.5 g of Woolite ® Delicate detergent per 0.5 L of water. A standard wash cycle was used (cotton/medium) with a standard spin cycle. (The sample was washed with 4-7 other printed fabric samples). The printed fabric sample was rinsed with 0.5 L water per sample for six minutes. The sample(s) was then spin-dried for five minutes and hung to air dry.
- the washed and dried samples were analyzed using a Gretag spectrophotometer for optical density, L, a*, and b* values.
- the image was printed using a standard DOD inkjet printer (Mutoh 90 lx) using standard dye sublimation inks onto Jacquard pretreated cotton. The image was heat pressed at 385°F for 35 seconds.
- Particle Size and Polydispersity Index The particle size and polydispersity of a pretreatment compostion was measured using ASTM E2490 (referring to the American Society for Testing and Materials standards) Standard Guide for Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS).
- Zeta Potential Zeta potential is the electrokinetic potential of a colloidal dispersion.
- the zeta potential of a latex dispersion (e.g., polyester latex, acrylic latex) and/or pretreatment composition may be measured using ASTM E2865 Standard Guide for Measurement of Electrophoretic Mobility and Zeta Potential of Nanosized Biological Materials.
- Fabric Hand The hand of a fabric measures the “feel” of the fabric against skin.
- the hand of a fabric can change with the printing of an image on the fabric. However, it is generally not desirable for the printed image to significantly impact the hand of the fabric, particularly for wearable products.
- the hand of a fabric was measured using standard AATCC EP 5 (referring to the American Association of Fabric Chemists and Colorists standards) Guidelines to the Subjective Evaluation of Fabric Hand. This standard uses a scale of 1-5 to characterize the hand of the fabric, where 1 is worst and 5 is best.
- Crock refers to the transfer of ink/dye from the fabric to another. For example, if the ink/dye of a printed image does not sufficiently adhere to the fabric, it may transfer to another substrate that it contacts. Ideally, the ink/dye of a printed image sufficiently adheres to the fabric to minimize any tendency for the ink/dye to crock.
- Crock may be tested using standard AATCC 8 Colorfastness to Crock: Crockmeter Method and a scale of 1 to 5, 5 being the best, and 1 being the worst. AATCC 8 includes testing methods for wet crock and dry crock as well.
- Weatherfastness may refer to the ability of a printed image on a fabric to withstand extended periods of weathering.
- weatherfastness may refer to a printed image’s ability to resist fading when exposed to ultraviolet light.
- a high quality printed image will have a higher tolerance to weather and will be able to resist fading due to ultraviolet light exposure.
- Weatherfastness may be tested using ASTM G154 Standard Practice for Operating Fluorescent Light Apparatus for UV Exposure of Nonmetallic Materials.
- Color Measurement The color uniformity of a printed image may be tested. In many cases, a higher quality printed image will have a higher uniformity. The color may be tested using ASTM D2244-16 Standard Practice for Calculation of Color Tolerances and Color Differences from Instrumentally Measured Color Coordinates.
- Table 1 and 2 shows pretreatment compositions with different types of latexes. Specifically, pretreatment compositions were prepared and tested using seven different latex polymers: Acrygen 61192 (50%) (Omnova Solutions), Eastek 1200 (30%) (Eastman), Vylonel MD-1100 (30%) (Toyobo), Eastek 1400 (30%) (Eastman), Vylonel MD-1480 (25%) (Toyobo), Vylonel MD-1335 (30%) (Toyobo), and Vylonel MD-1930 (31%) (Toyobo).

- Each latex composition was applied to a 100% cotton natural fiber fabric by spraying using a consumer spray bottle with spray trigger such that 0.11 g/in 2 composition was applied ( i.e Method of Pretreatment 1).
- An image was printed on the treated natural fiber fabric by printing the image using dye sublimation ink onto a standard transfer sheet with a drop-on- demand printer and transferring the image onto the dried natural fiber fabric using a heat press at 370 °F for 60 seconds.
- Table 3 below, provides the charge density, particle size, polydispersity index, zeta potential, fabric hand, crock wet, and crock dry of each sample, tested using the methods provided above.

- the particle size may be more than 15 nm, more than 20 nm, more than 25 nm, more than 30 nm, more than 40 nm, more than 50 nm, more than 60 nm, more than 70 nm, more than 80 nm, or more than 90 nm.
- the polydispersity index may also vary depending on the type of latex used. In some embodiments, depending on the latex, the polydispersity index used may be from about 0.1 to about 0.3. In some embodiments, the polydispersity index may be from about 0.15 to 0.25. Depending on the latex used, the polydispersity index may be less than 0.3, less than 0.25, less than 0.2, or less than 0.15. In some embodiments, the polydispersity index may be more than 0.1, more than 0.15, more than 0.2, or more than 0.25.
