Description

TREATED TEXTILE ARTICLE HAVING IMPROVED MOISTURE TRANSPORT
Background of the Invention (1 Field of the Invention
The present invention relates generally to treated textile articles and, more particularly, to a treated textile article formed from a synthetic fiber substrate and treated using a polyamide treatment agent for improved moisture transport.
(2) Description of the Prior Art
The current preference for garments made from cotton and other natural fibers is due, at least in part, to cotton's ability to wick moisture away from the body. However, cotton tends to absorb and retain moisture causing it to become less comfortable as more moisture is absorbed. Also, cotton garments tend to be slow drying. In contrast, synthetics, which tend to be hydrophobic, resist moisture transport and absorption. Thus, synthetic garments are quick drying.
The textile industry has focused efforts on developing synthetics that have the ability to effectively transport moisture away from the body while maintaining resistance to moisture absorption and quick drying characteristics. At the same time, the industry has directed research to improving synthetics' soil release, static dissipation, feel, fiber- to-fiber frictional properties, lumping of fiberfill after washing and wear life.
Some attempts have been made to modify moisture transport characteristics of a synthetic by reacting a modifying component to a synthetic polyether during initial polymerization or prior to spinning. However, this approach increases the drying time and negatively impacts numerous properties of the modified synthetic.
Other attempts have been made to modify moisture transport characteristics of a synthetic by adding a modifying component to the synthetic by melt blending. This approach relies on physical entrapment of the modifying component. However, this approach degrades physical properties and wastes the modifying component on the inside of the synthetic since its activity is required only at the surface.
Yet other attempts have been made to modify moisture transport characteristics of a synthetic by graft polymerizing a modifying component to the synthetic. However, this approach has not been commercially successful due to the difficulties in controlling the composition of the modified synthetic, environmental, health and safety issues, long reaction times and improper process equipment. Also, the modified synthetic fails to exhibit substantial and permanent improvements. Another approach to graft polymerizing has been to activate the surface of the synthetic using ionizing radiation. However, this approach requires specialized equipment and highly trained personnel, and is usually cost prohibitive.
Another approach has been made to modify moisture transport characteristics of the synthetic by the depositing of a modifying component from a bath onto the surface of the synthetic. In one approach, the synthetic is subjected to heat for drying and setting the modifying component on its surface. However, some of these approaches rely on ester linkages as the connective unit and because of hydrolysis/saponification under laundering conditions result in poor durability of the treatment agent. Other approaches function for one synthetic composition but are ineffective for others. Thus, there remains a need for a new and improved treated textile article formed from a synthetic fiber substrate having improved moisture transport while, at the same time, is sufficiently durable for home laundering.
Summary of the Invention The present invention is directed to a treated textile article formed from a synthetic fiber substrate including a polyamide treatment agent. In the preferred embodiment, the polyamide treatment agent includes between about 19 and 95 mole percent of a hydrophobic component.

Description of the Preferred Embodiments
In the following description, like reference characters designate like or corresponding parts throughout the several views. Also in the following description, it is to be understood that such terms as "forward," "rearward," "left," "right," "upwardly," "downwardly," and the like are words of convenience and are not to be construed as limiting terms.
A treated textile article of the present invention is formed from a synthetic fiber substrate including a polyamide treatment agent having a hydrophilic component and a hydrophobic component. A textile article may include any one of a filament, a fiber, a yarn, a fabric constructed from any one of fibers or filaments, yarn, and products made using at least one of a filament, a fiber, a yarn, and a fabric. Some examples of products contemplated include cloth, an article of clothing including protective clothing, rope, cable, and mesh, carpeting, non- woven fabric, ...etc. Those skilled in the art will appreciate that there exist numerous other examples of textile articles that are within the scope of the present invention and not specifically mentioned. A synthetic fiber substrate may be any one of a polyamide (also known as nylon such as nylon 6,6 and nylon 6, and including aramids such as NOMEX® polymer and KEVLAR® polymer), a polyester, an acrylic, a vinyl, polyurethane including a segmented polyurethane such as LYCRA® polymer that is generically known as spandex, and a polyalkylene such as polypropylene. Polyesters are any of a group of synthetic resins, such as DACRON® polymer or
MYLAR® polymer, that are formed by the polycondensation of carboxylic acids with
41180 dihydroxyl alcohols. Such resins may cure or harden, at room temperature under little or no pressure when catalyzed. Polyesters may be characterized by strength and resistance to moisture and chemicals.
Acrylics may include any of a large group of synthetic thermoplastic polymers created from various monomers (e.g., acrylic acid, methacrylic acid, esters of these acids, and acrylonitrile). These various monomers may polymerize readily when exposed to light.

x = about 40 or so
Spandex has a complicated structure, with both urea and urethane linkages in the backbone chain. Spandex is a polyurethane thermoplastic elastomer, which is available from E.I. du Pont de Nemours and Company, Wilmington, DE, USA under the trade name LYCRA® polymer. Spandex has both urea and urethane linkages in its backbone. The special properties of spandex are due to the fact that spandex has hard and soft blocks in its repeat structure. Short polymeric chains of a polyglycol, usually about forty or so repeats units long, are soft and rubbery. The rest of the repeat unit, the stretch with the urethane linkages, the urea linkages, and the aromatic groups, is extremely rigid. This section is stiff enough that it is believed that the rigid sections from different chains clump together and align to form fibers. Of course, they are unusual fibers, as the fibrous domains formed by the stiff blocks are linked together by the rubbery soft sections. The result is a fiber that acts like an elastomer. This allows the making of a fabric that stretches for exercise clothing and the like. Other terms for spandex include elastic fibers and elastane fibers
41180 Polyalkylenes may include any of a large group of synthetic thermoplastic polymers created from various monomers (e.g., ethylene, methylene, propylene, butylenes, etc.).

Unexpectedly, the polyamide treatment agent of the present invention appears to improve the surface properties of a number of synthetic substrates since it is unexpectedly a substantive agent for synthetic substrates such as any one of a polyamide (also known
41180 as nylon and including aramids such as NOMEX® polymer and KEVLAR® polymer), a polyester, an acrylic, a vinyl and a polyalkylene such as polypropylene.
The polyamide treatment agent may be applied in simple and safe application procedures using standard textile and laundering equipment. Further, the polyamide treatment agent may be incorporated into commercial and consumer detergent and softener (e.g., either a solid or liquid) and exhausted during laundering to impart or maintain improved moisture transport while at the same time imparting durability.
Applicants believe that the chemistry of the polyamide treatment agent of the present invention allows for use in higher pH processes such as those used in industrial and institutional laundering systems as well as in home laundering applications. The product can be added separately or in a formulated detergent as either liquid or powder or in a softener formulation in an effective amount to modify properties of textile articles including imparting improved moisture transport while at the same time imparting durability. Applicants further believe that a formulation that provides between about 0,05%) and about 1.5%>, preferably about 0.1% - 1.0% based on the weight of the textile article to be an effective amount.
Examples of conventional methods applicable to known textile equipment include pad/heat set, foam/heat set, and exhaust. Conventional textile wet processing methods applicable to such equipment include scouring, coloration, and fabric finishing. Potential points of application of the polyamide treatment agent in textile processing include any one of the fiber/yarn forming stage and the wet processing steps in the fabric stage. Within the fiber/yarn forming stage there are at least four points at which an effective amount of the polyamide treatment agent may be applied such as (1) to a spin finish after extrusion and before fiber drawing (e.g., the polyamide treatment agent may be applied on top of the conventional spin finish before fiber drawing); (2) to a fiber being or just drawn (e.g., the polyamide treatment agent may be applied using a metered finish applicator or a kiss roll); (3) before fiber crimping (e.g., the polyamide treatment agent may be applied by any one of a dip and nip bath, a kiss roll and a metered finish applicator then heat set onto the fiber's surface and resulting lower fiber to fiber frictional properties may improve crimping properties and yield a bulkier staple fiber); and (4) after-oiling or over-oiling (e.g., the polyamide treatment agent may be applied by passing
41180 a warp sheet over a kiss roll just ahead of a warp beam). Applicants believe that between about 0.05% and 1.0% based on the weight of the fiber to be an effective amount.
Other potential points of application of the polyamide treatment agent in textile processing may include any one during a formation of a non- woven article (with or without adhesives), as an additive in a cleaning/scouring step, as additives in a coloration bath, during a final fabric (including non-wovens) finishing. Final fabric finishing may include any one of foaming, spraying, drawing through a dip and nip bath and drawing through a kiss roll applicator followed by heating to a sufficiently high temperature and time for heat setting (e.g., temperatures between about 200 and 350°F for between about 1 and 3 minutes).
The polyamide treatment agent also may be combined or incorporated as a portion of any one of various processing aides by formulating a chemical auxiliary for any of these textile processes. For example, a treatment agent may be combined or incorporated as a portion of any one of a softener, a heat stabilizer, antioxidants, a dyeing auxiliary, a soil repellant, a fiber spin finish, a moisture transport auxiliary, ... etc.
For example, softeners may be any of silicones, amino silicones, fatty quats, fatty amido amine, ethoxylated amines, fatty alkanolamines or alkylolamides, fatty amphoterics, ... etc. A treatment agent combined or incorporated with one or more of these softeners may improve any of a textile article's hand, hydrophilicity, and hand and hydrophilicity.
A treatment agent combined or incorporated with one or more heat stabilizers may reduce a textile article's discoloration during heat setting. Likewise, a treatment agent combined or incorporated with one or more of antioxidants may reduce a textile article's discoloration during heat setting. For example, a soil repellant may be any of fluorocarbons, anionic polymers, ... etc. A treatment agent combined or incorporated with one or more soil repellants may act to extend the one or more soil repellants.
A treatment agent combined or incorporated with one or more dyeing auxiliaries may reduce repulsion between a textile article and the dying liquor. A treatment agent combined or incorporated with one or more fiber spin finishes may reduce fiber to fiber friction by lubrication and a treatment agent combined or incorporated with one or more antistats may reduce fiber to fiber friction by relieving electrostatic buildup in the textile article,
Such improvements are contemplated among woven and non- woven textile articles, either with or without an adhesive. Again, applicants believe that between about 0.05% and 1.0% based on the weight of the fiber to be an effective amount of the polyamide treatment agent.
The polyamide treatment agent may impart to a number of synthetic substrates improved moisture transport while, at the same time, imparting sufficient durability for home laundering. For example, it has been found that, unexpectedly, the polyamide treatment agent of the present invention may impart improved moisture transport to synthetic substrates while at the same time the moisture transport being durable to at least five home launderings. Unexpectedly, and in addition to improved moisture transport and durability, the polyamide treatment agent may impart improved static dissipation, soil release, fiber-to-fiber friction and "hand" properties. As used herein, hand is defined as the tactile qualities of a fabric, e.g., softness, firmness, elasticity, fineness, resilience, and other qualities perceived by touch.

7. Take remaining treated fabric subject to AATCC Test Method 130-2000 Section 8 Washing Procedure (4 consecutive home launderings) using about 100 grams of 1993 AATCC Standard Reference Detergent (American Association of Textile Chemists and Colorists, 1 Davis Drive, Research
Triangle Park, NC 27709) and water at a temperature of about 110°F.
8. Run through wash cycle again but use no detergent to insure that detergent has been completely removed.
9. Dry fabric in standard home dryer and then allow to condition for at least about 4 hours. ,
10. Cut the fabric into about 1"X 7"strips 3 courses and 3 wales for knits; 3 warps and 3 wefts for warpknits; and 3 warps and 3 fills for woven.

41180 Tests of substrates with no treatment (control) and after scouring, substrates with a treatment and no laudering, and treated and substrates with a treatment and after laundering were performed. These tests are described above and substantially correspond to the vertical strip wicking test mentioned by R.L. Barker, B. J. Scruggs, and I. Shalev, of the Center for Research on Textile Protection and Comfort, College of Textiles, North Carolina State University, Raleigh, NC in their paper entitled "Evaluating Operating Room Gowns: Comparing Comfort Of Nonwoven and Woven Materials" available in the The International Nonwovens Journal Volume 9, No. 1 (Spring, 2000) and online at http://www.inda.org/subscrip/iniOO l/ρ23.html. This test is accepted in the industry and further details concerning the test may be obtained from the Center for Research on Textile Protection and Comfort, College of Textiles (T-PACC), North Carolina State University, Raleigh, NC. For convenience, this vertical strip wicking test is refereed to in the claims as the "T-PACC vertical strip wicking test" In the T-PACC vertical strip wicking test, one end of a fabric strip about about 25mm wide X about 170 mm long is clamped vertically with the dangling end immersed to about 3 mm in distilled water at about 21°C. The height to which the water is transported along the strip is measured at 1, 5 and 10 minute intervals and reported in centimeters (cm).

In the present application, the water transported along the strip was measured at a 1 minute intervals for 5 minutes with the value at 5 minutes being reported in inches.
Table 1 contains a summary of moisture transport data for various treatment agents applied to the various substrates as well as untreated substrates. These data were used to compare the effect of moisture transport and moisture transport durability of a treatment agent treated textile fabric and. A number of treatment agent compositions where prepared as described in EXAMPLE 1 through EXAMPLE 34 below. The data summarized in Tables 5 through 38 were used to determine the hydrophobic component (mole percent) and the hydrophilic oxyalkylene derivative (weight percent). The data summarized in Table 1 were used to determine Normalized Average Moisture Transport Durability (inch/inch) (summarized in column 6 of Table 2), the ration of (Average Moisture Transport With Treatment and After Five Launderings)/( Average Moisture Transport With Treatment and No Launderings), (summarized in column 6 of
41180 Table 3) and the the ratio of (Average Moisture Transport With Treatment and No Launderings)/ (Average Moisture Transport With No Treatment and No Launderings) (summarized in column 6 of Table 4).
In determining the hydrophobic component (mole percent) and hydrophilic oxyalkylene derivative (weight percent applicants) also took into account the use of additives believed to act a plasticizers (Plast). For example, a plasticizer may be used for in making a hydrophobic component to lower the melt point and/or improve solubility with hydrophilic component during reaction. Examples of plasticizers that may be used include, but are not limited to, polyether glycol diamines having a molecular weight less than about 500 and the number of consecutive oxyethylene derivative units are less than about 4; polyether glycol diamines having a molecular weight greater than about 500 and the ratio of (oxyethylene derivative)/(oxypropylene derivative) and/or (oxyethylene derivative)/(oxybutylene derivative) less than about 4/6. An example is 2,2'-[l,2 ethanediylbis (oxy)] bis [ethaneamine] (Jeffamine XTJ-504 from Huntsman). Because it is believed that plasticizers may have a low moisture transport potential, plasticizers have been designated as part of the hydrophobic component. Recalling Structure I (S-I), Structure II (S-II) and Structure III (S-III) discussed above, the hydrophobic component (mole percent) becomes:
Moles S-I Units + Moles of S-II Units + Moles of Plast Units X 100
Moles S-I Units + Moles of S-II Units + Moles of S-III Units + Moles of Plast Units
Taking Sample 10 of EXAMPLE: 10 as summarized in Table 14 (Note: data in Tables has been rounded) one gets:
Moles S-I Units = 0
Moles S-II Units = 0.1422
Moles Plast Units = 0.0578
Moles S-III Units = 0.0916
Hydrophobic Component = 0.1422 + .0578 x 100 = 68.6%

Moles S-III Units = 0.1276
Hydrophobic Component = 00.2552 x 100 = 66.7%
(mole percent) 00.1276 + 0.2552
Again recalling Structure I (S-I), Structure II (S-II), Structure III (S-III), Structure T and Structure Plast discussed above, the hydrophilic component (weight percent) becomes (Based on polyether glycol diamines having a molecular weight greater than about 500 and the number of consecutive oxyethylene derivative units greater than about
4 or polyether glycol diamines having a molecular weight is greater than about 500 and the ratio of (oxyethylene derivative)/(oxypropylene derivative) or (oxyethylene derivative)/ (oxybutylene derivative) greater than about 4/6) : Mass S-III

FIGURE 1 is a graphical representation of the Normalized Average Moisture Transport Durability (inch/inch) data of Table 2 in the form of a variogram represented by contours for a treated textile article as a function of hydrophobic component content in mole percent and hydrophilic oxyalkylene derivative content in weight percent according to an embodiment of the present invention. The surface plot or variogram was generated using 3DField contouring surface plotting program available at any one of https://secure.reg.net/product.asp7DZN2631 ; http://field.hypermart.net/; and https://www.regsoft.net/regsoft/vieworderpage.php3?productid=31517. The 3DField contouring surface plotting program is authored by Vladimir Galouchko (e-mail: vdvgal@cityline.ru). The Block Kriging option was used to estimating the value of a block from a set of nearby sample values using kriging. Krining is a weighted-moving- average interpolation method where the set of weights assigned to samples minimizes the estimation variance, which is computed as a function of the variogram model and locations of the samples relative to each other, and to the point or block being estimated.

The polyamide treatment agent having the hydrophilic component and the hydrophobic
41180
74 component may be produced by any manner that results in an effective treatment. For example, the ingredients may be combined to react substantially simultaneously to generate the polyamide treatment agent having the hydrophilic component and the hydrophobic component (Process "A"). For example, in the manufacture of a desired polyamide treatment agent, precursors to the hydrophilic component and precursors to the hydrophobic component (with or without any one of catalysts, antioxidants and reducing agents) may be combined in a reactor. The combination may be heated to a temperature (e.g., between about 440°F and 560°F) that is sufficient to produce a reaction product that is a polyamide treatment agent. At temperature, the combination may be held for a sufficient amount of time (e.g., between about one and four hours) to produce a reaction product that is a polyamide treatment agent. Also, at temperature, the combination may or may not be subjected to any one of a vacuum, an inert atmosphere, and a reactive atmosphere.
Alternatively, ingredients that are precursors to the hydrophilic component may be combined to react followed by combining the hydrophilic component with or adding ingredients that are precursors to the hydrophobic component to react to result in a polyamide treatment agent and vice versa (Process "B"). For example, in the manufacture of a desired polyamide treatment agent, precursors (with or without any one of catalysts, antioxidants and reducing agents) to one of a hydrophilic and hydrophobic component of a polyamide treatment agent may be combined in a reactor. The combination may be heated to a first temperature (e.g., between about 350°F and 420°F) that is sufficient to produce a reaction product that is one of a hydrophilic and a hydrophobic component. At the first temperature, the combination may be held for a sufficient amount of time (e.g., between about one and four hours) to produce the reaction product that is one of a hydrophilic and a hydrophobic component. Then, the reaction product (which is one of a hydrophilic and hydrophobic component) and precursors (with or without any one of catalysts, antioxidants and reducing agents) to the other of the hydrophilic and the hydrophobic components of a polyamide treatment agent may be combined. The combination may be maintained at the first temperature or heated to a second temperature (e.g., between about 450°F and 560°F) that is sufficient to produce a reaction
41180
75 product that is the other of a hydrophilic or hydrophobic component of a polyamide treatment agent. At temperature, the combination may be held for a sufficient amount of time (e.g., between about one and six hours) to produce the reaction product that is the other of a hydrophilic or hydrophobic component of a polyamide treatment agent and, thus, a polyamide treatment agent. At any one of the first temperature and the second temperature, the combination may or may not be subjected to any one of a vacuum, an inert atmosphere, and a reactive atmosphere.
Yet another approach includes combining ingredients that are precursors to a hydrophilic component and ingredients that are precursors to a hydrophobic component and reacting at a first temperature for a time to produce the hydrophilic component followed by reacting at a second temperature for a time to produce the polyamide treatment agent by producing the hydrophobic component and vice versa (Process "C"). For example, in the manufacture of a desired polyamide treatment agent, precursors to a hydrophilic component and precursors to a hydrophobic component (with or without any one of catalysts, antioxidants and reducing agents) may be combined in a reactor. The combination may be heated to a first temperature (e.g., between about 300°F and 350°F) that is sufficient to produce a reaction product that is one of a hydrophilic or hydrophobic component of a polyamide treatment agent.
At the first temperature, the combination may be held for a sufficient amount of time (e.g., between about one and two hours) to produce the reaction product that is one of a hydrophilic or hydrophobic component of a polyamide treatment agent. Then the combination may be heated to a second temperature (e.g., between about 440°F and 560°F) that is sufficient to produce a reaction product that is the other of a hydrophilic or hydrophobic component of a polyamide treatment agent. At temperature, the combination may be held for a sufficient amount of time (e.g., between about two and six hours) to produce the reaction product that is the other of a hydrophilic or hydrophobic component of a polyamide treatment agent and, thus, a polyamide treatment agent. At any one of the first temperature and the second temperature, the combination may or may not be subjected to any one of a vacuum, an inert atmosphere, and a reactive atmosphere. Those skilled in the art will appreciate that instead of altering temperature, chemistry such as pH may be altered.

For example, it may be desirable to reduce any sedimentation that occurs from less soluble fragments of a polyamide treatment agent by incorporating dispersing aides including surfactants, natural polymer dispersants and synthetic polymer dispersants such as hydroxyethyl cellulose, guar gum, or xanthan gum.
Also, the polyamide treatment agent may be modified slightly, by the addition of between about 1%> and 7% by weight of the polyamide treatment agent of chain terminating monofunctional groups such as (R )d-F. These monofunctional groups may control molecular weight, to change solubility or to impact substantivity. Here R9 is any one of a C1-C24 alkyl, -C24 aryl, Cι-C24 alkylaryl, -C24 alkenyl, and oxyalkylene derivative (OAD) such as Rιo(O-CHR11-CHR12)P-. The subscript "d" = 1 or 2. The group F is any one of NH2, NH, COOR13, COC1, and a CHO. Rio is any one of a C1-C4 alkyl. Rπ is any one of a C1-C4 alkyl and hydrogen. R12 is any one of a C1-C4 alkyl and hydrogen. The subscript "p" is any value from 1 through 100. Rι3 is any one of a C1-C2 alkyl and hydrogen.
Alternatively, the polyamide treatment agent may be modified slightly by the addition of 1-3% of any one of polyamine such as diethylene triamine, triethylene tetraamine, tetraethylene pentamine, poly(oxy(methyl-l,2-ethanediyl), apha-omega-(2-aminomethylethoxy-, ether with 2-ethyl-2-(hydroxymethyl)-l,3 propanediol (3:1) and a polyacid such as trimellitic anhydride or citric to create more branching in the polyamide treatment agent.
The polyamide treatment agent made by any of the above-described routes may be distributed as any of a solid and a liquid. For example, a solid may be a flaked or ground agent that may be incorporated in a powdered detergent. Also, for example, a liquid may be an agent diluted in water as a solution or dispersion that is chargeable directly into the textile equipment. Techniques that may be used for a liquid include heating to a high temperature, homogenizing and agitating by high sheer.
The polyamide treatment agent having a hydrophilic component and a hydrophobic component of the present invention may be characterized by being water dispersible. It may be that a polyamide treatment agent is a substantive agent. That is, a
41180
77 polyamide treatment agent may be applied by immersing a synthetic substrate in a hot solution of the polyamide treatment agent in water.
