Definitions
- the invention relates to anti-soil application processes for bulk continuous filament (BCF) carpet and related textile fabrics, and specifically, to processes for applying anti-soil compositions on BCF yarns during cable or air twisting processes prior to weaving, knitting or tufting.
- the process foregoes the need to treat carpets and other textiles made from the BCF yarn, thus eliminating costly and environmentally unfavorable dyeing and low pH chemical treatment processes.
- Also disclosed herein are systems used to apply the anti-soil formulations to the BCF yarn, and soil repellant yarns, and carpets with improved anti-soil properties made from the BCF yarn of the disclosed process.
- Stain blocker e.g. acid dye blocker
- anti-soil with fluorochemicals are traditionally used.
- polyester carpets, such as 2GT and 3GT carpets, and polypropylene carpets anti-soil chemistry may be applied topically to the tufted carpet as part of the carpet finishing process.
- Polyester and polypropylene carpets typically do not require a stain blocker treatment because of inherent stain resistance to acid dyes and stains owing to their lack of amine end groups that function as acid dye sites.
- Topical application at the carpet mill can be in the form of exhaust application and spray application.
- Exhaust application i.e. flex-nip process at high (300-400 wt. %) wet pick-up
- Exhaust applications typically use higher amounts of water and energy to dry and cure the carpet than do spray applications.
- Spray-on fluorochemical products are designed to use less water and energy than exhaust applications, but they do not impart anti-soil properties that are as good as those provided by the exhaust applications owing to limited depth of penetration into the fabric, especially deep pile fabrics and those incorporating the tightly twisted yarns that are now becoming more popular.
- the carpet is also steamed and dyed first, steamed again, rinsed and extracted; and then a blend of SB and FC is applied together at high wet pick up, after which the carpet and chemicals are exposed once again to steam to fix the treatment, followed by drying.
- SB and FC are applied together at high wet pick up, after which the carpet and chemicals are exposed once again to steam to fix the treatment, followed by drying.
- low pH solutions, excess water, and energy are required for the SB and FC to penetrate the carpet and achieve uniform coverage.
- the typical prior art process is as follows: BCF yarn ⁇ Twist ⁇ heat set ⁇ tufting ⁇ carpet ⁇ dye ⁇ stain block/anti-soil.
- Carpets have also long been constructed of dyed or pigmented yarns, which constructions are treated in numerous possible ways, including the options of further dyeing, and the application of stain and/or soil resistant compositions with the concomitant use of steam and rinse water, as in the processes described above.
- the invention disclosed herein provides a process to make textile fabrics, especially tufted articles, without the requirement for subsequent stain and soil resistant chemistry application, thus avoiding the cost and waste of steam fixing and rinsing attendant with such large-scale fabric applications.
- the process involves application of topical chemistries to dyed or pigmented yarns immediately after twisting or cabling one or more such yarns together.
- the chemistries are then heat-set onto the twisted yarn under dry conditions, and the twisted yarn subsequently weaved or tufted into a finished fabric or carpet.
- Novel systems that enable the efficient application of topical chemistries to yarn subsequent to twisting and prior to winding and heat-setting are also disclosed.
- the disclosed process uses an atopical chemistry composition applicator positioned within a mechanical twisting process downstream of the twisted yarn take-up reel and upstream of the yarn winder.
- the disclosed process moves the backend, large scale and wasteful anti-soil application step, and if necessary, stain block application step, up front during yarn twisting.
- the carpet manufacturing process now becomes: BCF yarn ⁇ twist ⁇ FC (and optional SB) ⁇ heat set (optionally dry heat set) ⁇ tufting ⁇ carpet.
- the disclosed process is as effective, or even more effective, than processes of the prior art in terms of fabric soil resistance.
- the process of the disclosed invention is counter intuitive since treating the carpet yarn prior to heat setting and tufting is known to affect the quality of the finished carpet, particularly during dyeing. Further, the inventive process is also counter intuitive because soil resistant compositions tend to be very difficult to apply uniformly to twisted yarn bundles at the usual line speed without substantial waste. Moreover, the disclosed process is counter intuitive because the prior art yarn twisting apparatuses have not previously accepted topical chemistry applications to twisted yarn prior to winding. However, as shown below, Nylon carpets manufactured with the treated BCF yarn show superior anti-soil properties over the same carpets without such treatment.
- the anti-soil composition can be comprised of a high specific surface energy chemical or other material, for example a fluorochemical that imparts high specific surface energy properties such as high contact angles for water and oil, or even a non-fluorochemical particulate material having similar properties.
- the anti-soil composition can further comprise an anti-stain component.
- an untufted, twisted BCF yarn comprising an anti-soil component
- said anti-soil component is present on said twisted BCF yarn prior to tufting the BCF yarn.
- the anti-soil component is present at an on weight of fiber from about 100 ppm to about 1000 ppm.
- the yarn can comprise polyamide fiber and/or have polymer components selected from polyester and polypropylene.
- the yarn can be tufted and manufactured into carpet or fabrics.
- a system for applying an anti-soil composition to twisted BCF fiber comprises: (a) a first yarn take-up device that receives at least two individual yarn members and transmits a single yarn member; (b) an anti-soil composition applicator disposed downstream of said yarn take-up device that applies said anti-soil composition to said single yarn member; and (c) a second yarn take-up device that receives said single yarn member.
- the anti-soil composition can be comprised of a high specific surface energy chemical or other material, for example a fluorochemical that imparts high specific surface energy properties such as high contact angles for water and oil, or even a non-fluorochemical particulate material having similar properties.
- the anti-soil composition can further comprise an anti-stain component.

- FIG. 2 shows one aspect of the disclosed process.
- OWF On weight of fiber: The amount of chemistry that was applied as a % of weight of fiber.
- WPU Weight pick-up
- a process for treating twisted BCF yarn comprising contacting the BCF yarn with an anti-soil composition while said yarn is in motion and prior to contacting and winding the yarn onto a take-up reel or winder to create a yarn package or cake.
- the anti-soil composition comprises an anti-soil component and is adapted to be applied onto twisted BCF yarn at a wet pick-up of between about 5 wt. % and about 50 wt. %., including between about 10 wt. % and about 30 wt %, about 20 wt. % to about 30 wt. %, and about 10 wt. % to about 20 wt. %.
- the twisted BCF yarn can be optionally heat set after contacting the yarn with the anti-soil composition.
- Heat setting temperatures can range from about 125° C. to about 200° C., including from about 160° C. to about 195° C.
- Heat setting dwell times can range from about 0.5 to about 4 minutes, including from about 0.5 to about 3 minute and from about 0.5 to about 1 minute.
- Anti-soil components for use in the disclosed anti-soil compositions impart high specific surface energy properties such as high contact angles for water and oil (e.g. water and oil “beads up” on surfaces treated by it).
- the anti-soil component can comprise a fluorochemical dispersion, which dispersion may be predominantly either cationic or anionic, including those selected from the group consisting of fluorochemical allophanates, fluorochemical polyacrylates, fluorochemical urethanes, fluorochemical carbodiimides, fluorochemical quanidines, and fluorochemicals incorporating C-2 to C-8 chemistries.
- the fluorochemical can have less than or equal to eight fluorinated carbons, including less than or equal to six fluorinated carbons.
- Example fluorochemical anti-soil components include: DuPont TLF 10816 and 10894; Daikin TG 2511, and DuPont Capstone RCP.
- Non-fluorinated anti-soil components can include: silicones, silsesquioxanes and fluorosilanated and fluoroalkylated particulates, anionic non-fluorinated surfactants and anionic hydrotrope non-fluorinated surfactants, including sulfonates, sulfates, phosphates and carboxylates. (See U.S. Pat. No. 6,824,854, herein incorporated by reference).
- the anti-soil compositions can also have an optional stain blocker component comprising an acidic moiety which associates with polymer amine end groups and protects them from staining by acidic dye stains.
- the general category of chemicals suitable to the process of the instant invention can comprise any chemical that blocks positively charged dye sites.
- Stain blockers are available in various forms such as syntans, sulfonated novolacs, or sulfonated aromatic aldehyde condensation products (SACs), and/or reaction products of formaldehyde, phenol, polymethacrylic acid, maleic anyhydride, and sulfonic acid.
- the stain blocker is typically water soluble and generally penetrates the fiber while the anti-soil, usually a fluorochemical, is a non-water soluble dispersion that coats the surface of fiber.
- stain blockers include, but are not limited to: phenol formaldehyde polymers or copolymers such as CEASESTAIN and STAINAWAY (from American Emulsions Company, Inc., Dalton, Ga.), MESITOL (from Bayer Corporation, Rock Hill, N.C.), ERIONAL (from Ciba Corporation, Greensboro, N.C.), INTRATEX (from Crompton & Knowles Colors, Inc., Charlotte, N.C.), STAINKLEER (from Dyetech, Inc., Dalton, Ga.), LANOSTAIN (from Lenmar Chemical Corporation, Dalton, Ga.), and SR-300, SR-400, and SR-500 (from E. I.
- polymers of methacrylic acid such as the SCOTCHGARD FX series carpet protectors (from 3M Company, St. Paul Minn.); sulfonated fatty acids from Rockland React-Rite, Inc., Rockmart, Ga.); and stain resist chemistries from ArrowStar LLC, Dalton and Tri-Tex, Canada.
- the anti-soil composition is adapted to contact the twisted BCF yarn while it is in motion and prior to contacting the take-up reel or winder. Further, the anti-soil composition can be at a neutral pH (e.g. 6 to 8) because the yarn can be optionally heat set after application of the composition. The process foregoes the need for harsh low pH chemicals.
- any suitable device that applies wet ingredients to a dry substrate can perform the contacting.
- Such devices include, but are not limited to: applicator pad, ceramic tip, ceramic ring, nip rollers, wet-wick, dip-tank, sprayer, and mister.
- the contacting can be done by one or more devices, where each device can be the same or different.
- two, three, or more application devices can be used to apply the anti-soil composition at different points in the process.
- one or more application devices can apply an anti-soil component and one or more separate devices an anti-stain component. Multiple application devices and locations can provide better application uniformity when using certain BCF yarns.
- the wet pick-up of anti-soil composition is between about 5 wt. % and about 50 wt. %., including between about 10 wt. % and about 30 wt %, about 20 wt. % to about 30 wt. %, and about 10 wt. % to about 20 wt. %.
- the resulting twisted BCF yarn if a fluorine based anti-soil component is used, can have an on weight of fiber from about 100 ppm to about 1000 ppm fluorine, including from about 100 to about 500 ppm fluorine, from about 200 to about 400 ppm, and from about 100 ppm to about 300 ppm fluorine.
- the anti-soil composition further comprises a stain blocker, it is present on weight of fiber from about 500 ppm to about 4%, including from about 1000 ppm to about 3%, from about 0.5% to about 2%, and from about 0.5% to about 1%.
- Common stain blockers use sulfonated moieties as part of the chemistry, which results in the presence of sulfur on the treated fiber.
- the sulfur content can range from about 50 ppm with 5% stain blocker to about 1 ppm with 0.1% stain blocker on weight of fiber.
- the sulfur content on weight of fiber will range from about 0.5 ppm to about 40 ppm, including from about 1 ppm to about 30 ppm, from about 5 ppm to about 20 ppm, and from about 5 ppm to about 10 ppm.
- Sulfur content can be determined by x-ray diffraction or other methods.
- the anti-soil composition can further comprise a component selected from the group consisting of: odor control agents, anti-microbial agents, anti-fungal agents, fragrance agents, bleach resist agents, softeners, and UV stabilizers.
- the twisted BCF yarn can be made from polyamide fibers, such as those made from nylon 6,6, nylon 6, nylon 4,6, nylon 6,10, nylon 10,10, nylon 12, its copolymers, and blends thereof. Further, the twisted BCF yarn can also have additional polymer components, such as polyester and/or polyolefin components.
- the polyolefin component can be polypropylene.
- the additional polymer components can be incorporated with the polyamide (by melt-blend or co-polymerization) prior to making a polyamide fiber (e.g. a polyamide/polyester fiber), or can be stand-alone fibers that are twisted with the polyamide fibers to make the twisted BCF yarn.
- the BCF yarn can be manufactured with olefin, polyamide, and/or polyester polymer components.
- An unexpected benefit of the disclosed process has been discovered in that, whereas a small amount of anti-soil composition is applied compared to known exhaust processes, a high anti-soil component content, such as fluorine, is achieved on the surface of the yarn.
- the anti-soil composition applied in the process of the disclosed invention can be either fluorochemical or non-fluorochemical based, or a mixture of fluorochemical or fluoropolymer material with non-fluorinated soil resistant materials.
- the disclosed process may be applied to yarns that do not require subsequent dyeing, having either a pigment or pigment included in their composition prior to twisting.
- the pigmented yarns can be made by solution dyed as well as cationic and anionic dyed fibers.
- Yarns suitable for use in the process may further comprise inherent stain resistance, whether by base composition as in the case of polypropylene or polyester, or by the inclusion of strong acid functionality in the polymer composition of the yarn, as in the case of nylon.
- Use of dyed or pigmented yarns (i.e. colored yarns) with the disclosed process eliminates the need for subsequent dyeing and enables the creation of colored carpets that are soil resistant, without the need for subsequent dyeing and soil resistant chemical application.
- the twisted BCF yarn made with the various aspects of the disclosed process, by itself or blended with non-treated fibers and yarns, can be tufted and manufactured into carpets or fabrics.
- Carpets made with the twisted BCF yarn exhibit an oil repellency rating of 5 or higher and a water repellency rating of 5 or higher.

- the first yarn take-up device can be a take-up roll or reel that can twist the at least two individual yarn members into a single yarn member.
- the individual yarn members can be single filaments or fibers, or yarns made from a plurality of filaments or fibers.
- the applicator can be any suitable device that applies wet ingredients to a dry substrate, including, but not limited to: applicator pad, nip rollers, wet-wick, dip-tank, sprayer, and mister.
- the wet pick-up of composition is between about 5 wt. % and about 50 wt. %., including between about 10 wt. % and about 30 wt %, about 20 wt. % to about 30 wt. %, and about 10 wt. % to about 20 wt. %.
- the resulting twisted BCF yarn if a fluorine based anti-soil component is used, can have an on weight of fiber from about 100 ppm to about 1000 ppm fluorine, including from about 100 to about 500 ppm fluorine, from about 200 to about 400 ppm, and from about 100 ppm to about 300 ppm fluorine.

- nylon 6,6 carpets made from two 922 denier beige color solution dyed BCF fibers that have been treated various aspects of the process disclosed above and similar fibers with no treatment. Selection of alternative anti-soil components and stain blocker components, fibers and textiles having different surface chemistries will necessitate minor adjustments to the variables herein described.
- Acid dye stain resistance is evaluated using a procedure modified from the American Association of Textile Chemists and Colorists (AATCC) Method 175-2003, “Stain Resistance: Pile Floor Coverings.” 9 wt % of aqueous staining solution is prepared, according to the manufacturer's directions, by mixing cherry-flavored KOOL-AID® powder (Kraft/General Foods, White Plains, N.Y., a powdered drink mix containing, inter alia, FD&C Red No. 40). A carpet sample (4 ⁇ 6-inch) is placed on a flat non-absorbent surface. A hollow plastic 2-inch (5.1 cm) diameter cup is placed tightly over the carpet sample.
- AATCC American Association of Textile Chemists and Colorists
- KOOL-AID® staining solution Twenty ml of the KOOL-AID® staining solution is poured into the cup and the solution is allowed to absorb completely into the carpet sample. The cup is removed and the stained carpet sample is allowed to sit undisturbed for 24 hours. Following incubation, the stained sample is rinsed thoroughly under cold tap water, excess water is removed by centrifugation, and the sample is dried in air. The carpet sample was visually inspected and rated for staining according to the FD&C Red No. 40 Stain Scale described in AATCC Method 175-2003. Stain resistance is measured using a 1-10 scale. An undetectable test staining is accorded a value of 10.
- the repellency rating of the sample is the highest rating number liquid used to pass the repellency test. Carpets with a rating of 4 or higher have good anti-soiling properties. Without anti-soil treatment, most nylon carpets have a rating of 1 for both oil and water repellency.

- the cable twisted yarn went through the wet wick at about 50 ypm.
- the cable twisted yarn was subsequently heat-set on a Suessen with 200° C. dry air.
- the holdup time in the channel was about 60 seconds.
- the heatset yarn was analyzed to have 270 ppm Fluorine.
- the heat treated yarn was converted into a 35 oz per square yard, 1/12 gauge, 3 ⁇
- Table 1 below reports the repellency and stain tests of the four examples.
- carpets made from the treated BCF yarn show excellent and good oil and water repellency ratings. This indicates that the disclosed inventive process is an acceptable replacement to existing exhaust type applications for applying anti-soil compositions to carpets and fabrics.
