Definitions

  • Aromatherapy is a popular trend and been found to be beneficial for many people. That benefit could be extended with a fabric with infused scents that will remain in the fabric after several washings: a lavender-infused fabric for bed sheets, for example. Numerous attempts at achieving that or a similar result can are found in the art and cluster among two ways of obtaining such a fabric.
  • One way is to finish a woven or knitted fabric by an application of a substance that adheres to the fabric and gives off the aroma in the final product.
  • the other way is to make (spin) a synthetic fiber, and cache the fragrant compound within the fiber (such as by locating it in voids within the fiber). That fiber is used to make a yarn, and then weave or knit the yam into the fabric form. But success has been elusive.
  • the fragrance is present in or attached to the fabric as a finite quantity of the substance that has aroma (fragrance source), and the sensation of smelling the fragrance occurs as molecules of the substance emanate from the fabric to the nose of the person experiencing the fragrance. That process inherently depletes the quantity of the fragrance source over time, until the number of molecules that can emanate becomes so small that the fragrance experience is diminished or lost. Laundering, as in a home laundry, can wash out some or all of the fragrance and accelerate the loss of fragrant effect.
  • the present invention addresses one or more of those needs in the art by providing a fragrant fabric comprising a fabric substrate and microcapsules of a fragrant material adhered to the fabric substrate with an acrylic or acrylic-styrene copolymer formulation.
  • the fabric substrate may be cotton, such as a preshrunk,
  • microcapsules may be adhered to the fabric substrate with a carboxylated, heat-reactive, styrene-acrylic copolymer or a high-solids, self- crosslinking, acrylic polymer.
  • the fabric substrate is preshrunk woven cotton and the microcapsules are adhered to the fabric substrate with a high-solids, self- crosslinking, acryhc polymer.
  • the invention can be considered as a fragrant fabric made by passing a woven cotton fabric substrate through a foam applicator, and applying a foam to the fabric substrate in the foam applicator, and drying the fabric.
  • the foam includes acryhc polymer, microcapsules containing a fragrant material, a surfactant and water.
  • the invention can also be considered as a method of applying fragrance to a fabric comprising providing a fabric substrate, providing a foam containing an adhering material and microcapsules of a fragrant material, passing the fabric substrate through a foam apphcator, applying the foam to the fabric substrate in the foam apphcator, and drying the fabric substrate and foam.
  • Providing a fabric substrate may include providing a woven cotton fabric substrate.
  • Providing a fabric substrate may include bleaching a cotton fabric substrate, mercerizing the cotton fabric substrate, and preparing the cotton fabric substrate for dyeing.
  • Applying the foam to the fabric substrate in the foam apphcator may include applying the foam using a top apphcator of a foaming machine to apply the foam to a face of the fabric substrate. Applying the foam to the fabric substrate may include applying the foam in a wet-pickup range of 25% to 10%
  • Providing a foam may include providing a foam with a bonding material, a surfactant, water, and microcapsules of a fragrant material.
  • the bonding material may be a carboxylated, he at -re active, styrene-acrybc copolymer.
  • the bonding material may also be a high solids, self-crosslinking acrybc polymer emulsion. Applying the foam may be at 15% wet pickup, a blow ratio of 15-20, and drying may be at 230°F (110°C).
  • the surfactant may be an amine oxide.
  • the bonding material, surfactant, water, and microcapsules of a fragrant material may be present in the foam in a ratio of about 40% bonding material, about 2% surfactant, about 45% water, and about 13% microcapsules of a fragrant material.
  • the fabric substrate can be made by weaving, knitting (circular knit or warp knit) or otherwise manipulating the yarn or fibers to form a fabric substrate.

  • a particular sheeting, PFGD is preshrunk 59 inch (149.9 cm) 4.2 oz./sq. yd. (142.4 gm/sq. meter), white, 100% Combed Cotton.
  • the fragrance is applied to the PFGD fabric substrate as foam in a foam applicator.
  • the foam applicator is available as a Chemical Foam System from Gaston Systems, Inc. of Stanley, North Carolina and includes a generator and an applicator.
  • the generator is used to mix the items to go into the foam, and the applicator has a pathway for a fabric substrate that exposes the fabric substrate to foam from the generator that is applied to the fabric substrate as it passes through the applicator.
  • a foam applicator that may be suitable for use is available from Prism Textile Machinery of Bengal, India, which sells wide range of foaming equipment to companies who wish to finish fabrics using foam technology.
  • One embodiment of the foam uses a formulation of an acrylic polymer bonding material, microcapsules of fragrance, a surfactant that helps with frothing, and water.
  • the acrylic polymer bonding material may be Unibond 1779, available from Unichem, Inc. of Haw River, North Carolina. UNIBOND 1779 is a high-solids, self-crosslinking, acryhc polymer emulsion.

  • a suitable bonding material or agents can be used.
  • a suitable surfactant is Unifroth 1942, also available from Unichem.
  • Unifroth 1942 is a surfactant designed for use as a non-rewetting wetter at low levels, or as a foaming agent at higher levels.
  • the non-rewetting nature comes from its ability to degrade under drying or curing temperatures. This property allows the fabric to both wet-out thoroughly in the application bath and yet have no residual surfactant properties left after drying and curing.
  • Unifroth 1942 is a clear liquid with an activity cf 33.0 %, a pH of 7.0 to 8.5 and is completely soluble in water. Other suitable surfactants can be used.

  • the microcapsules can be sourced commercially.
  • the foam application method replaces traditional water-based application methods and is more energy efficient than the water-based finishing and application.
  • the foam can be applied to the fabric substrate in a top applicator of the foam applicator, and various wet-pickups can be used, such as 10% to 25%. Once the foam has been applied to the fabric substrate, they are dried, such as at 230°F (110°C).
  • Samples were made using Unibond 1779 and Unibond 1919-SC.
  • the foam was made up of 45% water, 40% bonding material (either Unibond 1779 or Unibond 1919-SC), 13% lavender microcapsules and 2% Unifroth 1942.

  • the drying temperature of the fabric substrate after foam application was 230°F (110°C).
  • the method can be used with a range of fabric substrates, and the parameters such as the binders may change.
  • Various fabric substrates with various scents can be used, such as rose-scented wool blankets, lavender-scented underwear, among many others.
  • Various fibers can be used in the fabric substrate, including wool, wool-blends, cotton, cotton-blends, polyester, rayon, nylon, polyester, spandex, elastomers, acrylic, rayon, ramie, silk, bamboo, linen, sisal, viscose, flax, hemp, jute, and mixtures or blends thereof.
  • the scents can be made available as essential oils, some of which are thought to have anti-microbial properties.

Additional scents that may be suitable for inclusion as fragrance sources are listed in Tables 1-4 .
  • Aroma categories Sources of the fragrances, aromas and scents mentioned in tables 1-4 may be suitable for use as the fragrance.
  • Apparel fabric substrates can also be made.
  • undergarments can be provided with a scent.
  • Scents can be scents conventionally known for use in aromatherapy, or can be perfume-like scents or functional scents such as insect repellents (DEET or permethrin) or antimicrobials.
  • the added material can be cannabidiol (CBD).
  • Silver can be added to fibers or filaments to act as an antimicrobial, such as is done by the technology of PurThread Technologies, Inc. of Cary, North Carolina, disclosed in U.S. Patents 9,878,480 and 9,908,987. Those fibers or filaments can be positioned as desired in the fabric substrate.
  • microcapsules need not be homogeneous, but could be a mixture of microcapsules to provide multiple properties. Microcapsules that will fracture differently under different conditions can be used together, so that some fracture and release their contents at one time, and others at another time, to provide a timed-release effect.
  • the microcapsules can be added to the mattress ticking that covers the mattress.
  • the adhesive materials in the foam can be much more aggressive in holding the microcapsules to the fabric substrate, since there is less need to be as concerned about having a good resulting “hand.”
  • people do not come into contact with the ticking, so if the ticking feels tacky or harsh, that is of much less concern than if the fabric is the bedsheet. Since the ticking is almost never washed, there is less need for wash fastness.
  • the mattress is usually covered with a mattress pad, sheets, etc. so the rate of transfer of the fragrance to the atmosphere is inhibited, slowing the depletion of the reservoir of fragrance on the ticking.
