- the tensioned filament After passing around the adhesive roller, the tensioned filament lies in a horizontal line and passes through a feather-applying chamber like the one disclosed in my aforesaid pending application Serial No. 276,985, where feathers and feather fibers are blown against the adhesivecoated filament, causing the filament to be completely covered. Due to the nature of feathers and the way they are handled in the machine, the feathers are orientated, their quills being foremost or in advance of the barbs as the feathers travel with the air currents. Thus, the quills usually strike the filament and become attached thereto by the adhesive, the quills usually arranging themselves at approximately right angles to the filament.

SIMULATED DOWN FILLER AND METHOD OF MAKING THE SAME Filed Aug. 8, 1952 2 Sheets-Sheet 2 F- 3 /BF/YIDE/WCK g. BY ATTORNEY SEMULATFZD DQWN HELLER AND METHQD 9F MAKING THE SAME Edward R. Frederick, Pittsburgh, Pa, assignor to the United States of America as represented by the Secretary of the Army Appiication August 8, i952, Seriai No. 303,327 13 Qiaizns. (CE. EFF-4) This invention relates to simulated down fillers and a method of making the same, and is an improvement on the invention described and claimed in my pending application Serial No. 276,985, filed March 17, 1952.
in said pending application disclosure is made of a method including spiralizing a wire or monofilament, coating the tensioned wire or monofilament with an adhesive, blowing a feather product against the coated tensioned wire or monofilament to cover the latter, then cutting the covered wire or monofilament and relieving its tension so that a feather-covered helix or spiral of controlled length and diameter is obtained. As there disclosed, a plurality of such helices or spirals may be employed advantageously as filler elements in various fabric and other constructions, since they provide a high bulk to weight ratio, are good heat insulators, oflfer considerable resistance to lateral compression while permitting flexing and lengthwise expansion and contraction, and have other desirable characteristics.
In accordance with this invention, a feather-covered monofilament of any desired length is provided but the monofilament lacks a regular spiral or helical form, having instead an irregularly curled, twisted form as will be explained. The irregularity of the curly form is such that probably no two sections or fragments of the covered monofilament are identical. When the described covered monofilament is cut into short lengths and batts are formed therefrom, such batts have high filling power and can be substituted advantageously for the waterfowl feather-and-down mixture now in common use for sleeping bags, etc. The invention also provides an extremely simple and inexpensive procedure for making the described covered monofilaments.
For an explanation of the term filling power, reference may be made to the report entitled A proposed method for measuring the filling power of down and feathers by Henry A. Sinski, publication No. TD 103037, The Office of Technical Services, U. S. Department of Commerce, and to the article by N. B. Edelman in Textile Research Journal, vol. 17, p. 199 (1947) entitled Investigation of methods for determining the filling power of feathers.
In the accompanying drawings forming a part of this specification,
Fig. 1 is a flow sheet or diagram of the method;
Fig. 2 is an enlarged reproduction of a goose down particle;
Fig. 3 is an enlarged reproduction of a fragment of a feather-covered monofilament made in accordance with this invention, the enlargement being the same as Fig. 2; and
Fig. 4 is a full size elevation of a polyethylene monofilament after being shrunk about 80% In practicing the invention, the monofilament selected is preferably polyethylene, preferably of about .010 in. diameter. This monofilament has a specific gravity of only 0.920.93 and has the valuable characteristic of shrinking, thickening, and curling or twisting when exposed to moderate heat (about 250 F.). It also has low water absorption, remarkable chemical inertness, high dielectric strength and unusual low temperature a or equal 40% or even more.
2,7l3,547 Patented July 19, 1955 flexibility. Usually monofilaments as they come on the market have been stretched, and therefore a pre-tensioning is not necessary; but if the monofilament has not been stretched, the first step is to apply tension in any usual manner to stretch it 5% or more. The stretched monofilament, still under tension, is then run around a roller dipping in a bath of adhesive (not shown) to apply a coating of adhesive to the monofilament. For the adhesive I prefer to employ Pliobond 20, which is said to be a butadiene-acrylonitrile rubber type adhesive, made by the Goodyear Tire & Rubber Co. This adhesive forms a positive bond so strong that chicken feathers and feather fibers attached to the monofilament by the adhesive may be pulled apart before the bonds will yield. Pliobond 20 is extremely tacky, is vuncanizable, dries satisfactorily under the conditions obtaining, and is not brittle at low temperatures (65 F.), nor does it disintegrate or fiow at +120 F. While this adhesive as at present marketed has an objectionable odor, perhaps due to a volatile ketone, the odor disappears in time; if desired, deodorants or aeration may be used to shorten the period during which the odor is noticeable.
After passing around the adhesive roller, the tensioned filament lies in a horizontal line and passes through a feather-applying chamber like the one disclosed in my aforesaid pending application Serial No. 276,985, where feathers and feather fibers are blown against the adhesivecoated filament, causing the filament to be completely covered. Due to the nature of feathers and the way they are handled in the machine, the feathers are orientated, their quills being foremost or in advance of the barbs as the feathers travel with the air currents. Thus, the quills usually strike the filament and become attached thereto by the adhesive, the quills usually arranging themselves at approximately right angles to the filament.
The air stream, of course, helps to dry the adhesive to make a reasonably firm bond before the covered filament passes out of the machine.
The feathers used are preferably straight chicken feathers not over 3 in. long or commercial curled (i. e., crushed) chicken feathers or feather fibers, or mixtures of these in any proportions. These feathers or fibers are preferably washed or dry cleaned and then coated with an elastomer, a wax or a resin, as disclosed in my pending application Serial No. 276,985; or the feather product may be chemically treated as disclosed in my pending application Serial No. 287,427, filed May 12, 1952, or in the Frederick and Janowski application Serial No. 343,806, filed March 20, 1953. Chicken feathers or chicken feather products are prefered because of the large quantity available; other land fowl feathers and feathers products may, however, be used. Waterfowl feathers and down are disclaimed.
After the covering, the filament is cut or chopped into convenient lengths, which may be as much as ten inches or as little as one inch or even less. These feather-covered fragments are then subjected to heat, conveniently heated air currents in a closed thermostatically controlled chamber with the temperature about 250 F. High temperatures are avoided to prevent undesirable changes in the feathers. This heating effects a 30-40% reduction in length due to shrinkage, which, of course, brings the feather fibers closer together. If the pre-stretching mentioned above has taken place, the shrinkage will approach As a pronounced twisting and curling also takes place (see Fig. 4), the fragments have their feather barbs or fibers extending outwardly in all directions, generally like waterfowl down. Fig. 4 also shows how a filament (originally 0.010 in. diam.) thickens as it shrinks in length. In this instance, the shrinkage was about 80% due to exposure to a temperature of 300 F. for about ten minutes. Fig. 3 reproduces on an enlarged scale a covered filament fragment made as described. Fig. 2 shows on the same scale a goose down particle, for comparison.
The filling power of the described product is high, about 4.3 to 4.5 in case untreated feathers are used. With treated feathers, the filling power may reach 5.3 to 5.9; hence masses or batts formed from the product may be used as substitutes for the standard down-feather mixture now used in Army sleeping bags.
While polyethylene monofilament has been particularly described because of its perfect adaptability to the method of the invention, other heat-shrinkable filaments may be used, provided the degree of heat necessary for effecting the shrinking does not impair the bond or damage the feathers. For instance, vinyon H monofilament, which is a vinyl chloride-vinyl acetate resinous filament of about 87% vinyl chloride content may be used, or vinyon N thread (an acrylonitrile-vinyl chloride resinous thread of about 60% vinyl chloride content) may be employed as the core. The properties of various vinyon N yarns are described in Industrial and Engineering Chemistry, vol. 40, No. 9, p. 1724 (September 1948). Among the patents relating to vinyon H are Rugeley et al. Nos. 2,161,766 and 2,344,002; while the Shriver et al. Patent No. 2,420,330 and the Rugeley et al. Patent No. 2,420,565 relate to vinyon N.
