Definitions

  • This invention generally relates to protective fabrics and covers. More specifically, the invention relates to protective fabrics which have enhanced allergen barrier capabilities, rendering them particularly useful as a barrier to allergens and the like.
  • the house dust mite (Dermatophagoides pteronyssimus), which is a member of the spider family, measures about 0.3 mm across and to the naked eye, is indistinguishable from a speck of dust. It accounts for a large percentage of the mite population in samples taken from homes. Because the house dust mites require a moist environment and feed on such things as human skin, they are typically concentrated in high numbers in and around beds and bedding items.
  • dust mite allergies generally recommend encapsulation of pillows and mattresses, to prevent the cross-transfer of dust mites from these articles to the allergy sufferer. Furthermore, such individuals are instructed to wash all non-encapsulated bedding articles frequently at the hottest temperatures tolerable, to kill any dust mites which may be living therein.
  • barrier-type covers available on the market include ones which are plain woven from polyester and those which are plain woven from a polyester/cotton blend. These fabrics are typically very tightly woven, to minimize the size of the openings therein through which the dust mites can travel. Although providing barriers for some particles and some superior comfort characteristics as opposed to their plastic coated or film-containing counterparts, such fabrics can fail to prevent the transfer of other common particles, thereby providing ineffective barrier properties for some purposes. Furthermore, they can have poor comfort and aesthetic properties as well due to their plastic feel and thickness. Summary
  • the instant invention overcomes many of the disadvantages of the prior art barrier fabrics, while providing superior performance characteristics.
  • the fabrics of the instant invention are desirably lightweight, thin, have good moisture transport properties, and have superior allergen filtration characteristics. They are desirably tightly woven in a relatively lightweight construction, calendered, then desirably face finished, thereby improving the hand and aesthetic characteristics.
  • the fabric is woven from substantially all-polyester.
  • microdenier polyester yarns are desirably used in at least one of the yarn sets forming the fabric (i.e. the warp or fill direction) while standard-sized polyester yarns are used in the other direction.
  • the term microdenier yarns is intended to describe those yarns made from filaments which are 1 denier per filament in size or less.
  • microdenier yarns can be provided in both of the yarn sets forming the fabric (i.e. both the warp and fill).
  • the fabric is made from a blend of polyester and cotton fibers.
  • polyester yarns can be used to form one of the yarn sets while cotton yarns can be used to form the other of the yarn sets forming the woven fabric.
  • the woven fabrics are then desirably calendered on at least one side. If desired, the fabrics can be calendered on both sides by passing the fabric back through the calender a second pass or in some other manner.
  • calendering a single side of the fabric results in a fabric having barrier properties sufficient to resist the passage of allergens to a significant extent.
  • the fabrics are also desirably face-finished, by sanding, sueding or the like.
  • the fabrics are desirably subjected to a face finishing process which contacts the fabrics at an angle with one or more abrasive rolls, to abrade the fibers on the surface of the fabric.
  • Fabrics of the instant invention have been found to be effective barriers from dust mites, as tested both according to airflow and use simulation tests. In addition, the fabrics have been found to have dramatically greater effectiveness as a barrier to cat dander allergen (Fel d1.)
  • the fabrics of the instant invention can be used for a variety of purposes, including but not limited to the production of protective covers for upholstered and padded articles such as furniture and bedding items (e.g. mattresses, comforters and pillows.)
  • the fabric can be used to form a cover for covering a portion of a mattress (e.g. in the form of a mattress pad or a regular fitted sheet), a mattress encasing (for surrounding substantially the entire mattress), a pillow encasing or the like.
  • the fabric forms a mattress covering, it is preferred that the fabric at least form the platform (i.e. the user contacting surface) of the mattress covering.
  • the items can be designed to be used alone or in combination with other bedding articles, such as sheets and the like.
  • the cover can form a portion of the pillow covering or the mattress ticking, the furniture upholstery, or the like.
  • Fig. 1 is a flow diagram of a process which can be used to produce the fabric of the instant invention
  • Fig. 2 is a schematic representation of the process of Fig. 1 in a batch process
  • Fig. 3 is a schematic representation of a continuous process which can be used to produce fabrics according to the instant invention.
  • the fabric 10 is initially passed through a scouring range 12 where the fabric is scoured and dried. From the scouring range, the fabric passes through a set of calender rolls 14 where it is calendered on at least one side. From the calendar rolls 14, the fabric 10 passes through a face finishing device 16 such as a sander.
  • the face finishing device serves to roughen the fibers on the surface of the fabric; preferably the surface of the fabric opposite that which was calendered is face finished, although it is noted that both surfaces of the fabric can be calendered and/or face finished within the scope of the instant invention.
  • the face finishing device contact the fabric at angle in the manner described in commonly-assigned U.S. Patent No.
  • the fabric desirably passes through a lint extractor 18 to a collection container 20, from whence it passes through a heat setting range to a take up (not shown.)

  • the fabric also desirably has an air permeability of at least about 1 , and preferably at least about 2 cfm at 125 pa's.
  • the fabric also desirably allows an airflow of at least about 15 l/min, and more preferably at least about 20 l/min, and even more preferably at least about 23 l/min.
  • the fabric also desirably allows the passage of less than 1 ng of cat dander allergen when subjected to a Fel d1 cat dander allergen airflow test, more preferably less than about .5 ng of Fel d1 cat dander.
  • the fabric allows the passage of less than about .31 ng of cat dander allergen, as this is generally considered to be an effective barrier to the passage of Fel d1 cat dander allergen.
  • the fabric also desirably allows the passage of less than about 1.3 ng of Der f1 dust mite allergen when subjected to an airflow test, as this is generally considered to be the level at which the fabric functions as a dust mite allergen barrier.
  • the fabric also desirably functions as a dust mite allergen barrier in use simulation testing, by allowing the passage of les than about 3.9 ng of Der p1 and Der f1 dust mite allergen.

  • Moisture Vapor Transmission Moisture vapor transmission was tested in accordance with ASTM Designation E96-93. It is generally considered that variations in MVTR must be ⁇ 25 g/sq m/24 hrs to have effective significance in comfort differentiation.
  • Mite Allergen and Cat Dander Allergen Airflow Test An apparatus based on the design reported by Vaughan, JW et al (JACI 1999; 103:227-231 ) was used to test allergen barrier properties of the fabrics. Airflow measurements were calibrated against a fabric control with a known airflow rate. Five hundred milligrams of a dust sample with known amounts of the indicated allergens were pulled across each fabric. A filter cassette mounted downstream from the fabric collected any allergen that was able to penetrate the fabric. The filter was extracted in 2.0 mL of 1 % BSA in PBS-Tween 20 overnight. The extract was assayed the following day with an ELISA for the relevant allergen.
  • the allergens measured were Mite allergen (Der p1 and Der f1 ) and Cat allergen (Fel d1 ).
  • the dust samples included 8982 ng of Fel d1 and 1015 ng of Der fl , respectively. It is generally considered that fabrics having a Fel d1 measurement of ⁇ .31 would be an effective barrier to cat dander allergen transfer (smaller particle size) and fabrics with a Der f1 measurement of ⁇ 1.3 would be an effective barrier to dust mite allergen transfer.
  • Mite Allergen Use Simulation A sieved reference dust sample containing a known quantity of the indicated allergen was loaded into one side of the special dual chamber along with two steel bearings. The fabric doth being investigated was inserted as the barrier between the empty and dust containing sides of this chamber. Each side of the chamber is a glass vial (2.1 cm diameter by 4 cm length) with a transfer surface area between the two vials of 1.13 cm 2 . The chamber was rotated at 25 rotations per minute for 18 hours. The two 1/8" steel bearings in the allergen vial weighed 132 milligrams each.
  • the empty side was tested for the presence of allergen by a sensitive enzyme immunoassay with a limit of detection of 3.9 nanograms of dust mite allergen.
  • a sensitive enzyme immunoassay with a limit of detection of 3.9 nanograms of dust mite allergen.
  • the allergen loaded included 0.250 grams of fine dust containing 6250 nanograms of dust mite allergen.
  • the fabrics of the instant invention have dramatically improved results as a barrier to cat dander allergen.
  • the improved barrier was achieved without a reduction in comfort, as evidenced by the comparable moisture vapor transmission rates and airflow properties for the commercial products and those of the instant invention.
  • the lower warp sled friction values suggest it may be easier to install such things as mattress covering made from the fabrics of the invention as compared with those of the prior art, since the warp direction would generally correspond to the direction of fabric installation.
