Description

Nov. 21, 1961 w. v. M CRARY REVERSIBLE BLANKET Filed Feb. 18, 1957 REPEAT 01- PM LING i g. 3 INVEN TOR. a e W/LLIAM K MCCRARY BY States Pate This invention relates to Woven blankets, and more particularly to an improved weave construction by which reversible faces (i.e., faces of different color) may be formed eifectively in a lightweight blanket structure.

The improved weave construction of the present invention is characterized by a double weave in which a relatively high warp density is employed, but in which a majority of the warp is arranged in floating relation at each filling pick so that the pick count can be reduced substantially without encountering subsequent difiiculty in preventing different colored fillings at the opposite faces of the weave from bleeding through upon napping.

More specifically, the double weave of the present in vention is arranged with each warp end running alternately under a group of four top face and one bottom face filling picks and over a group of one top face and four bottom face filling picks, and with any five adjacent warp ends disposed l-up in relation to any top face filling pick, l-down in relation to any bottom face filling pick, and three ends floating in relation to all filling picks.

These and other features of the present invention are described in further detail below in connection with the v accompanying drawings, in which:

FIG. 1 is a pattern chart for the improved double weave construction of the present invention;

FIG. 2 is a fragmentary diagram illustrating the relative interlacing of any five adjacent warp ends in a blanket cloth incorporating the weave construction of the present invention; and

FIG. 3 is a further fragmentary diagram illustrating the warp end arrangement fillingwise at a pair of top and bottom face filling picks.

In the pattern chart of FIG. 1 the warp ends are shown repeating in groups of five adjacent ends designated by the reference characters a, b, c, d and e (the warp end being up at the marked squares), and the repeat of the filling is shown to include 20 picks indicated by the reference numerals l to 20, inclusive. As it is a reversible blanket that is being formed by the double weave construction of the present invention, the top and bottom filling picks are formed with different colored yarn and the filling pick sequence must be arranged so that the shooting and return picks run in pairs of the same color. Accordingly, the filling pick 1 in FIG. 1 and throughout the remainder of the drawings, is illustrated as being the return pick of the top face filling color, while filling picks 2 and 3 are in turn the shooting and return bottom face picks of the other color, filling

picks

4 and 5 are the shooting and return top face filling picks of the first color, and so on. On this basis,

picks

1, 4, 5, 8, 9, 12, 13, 16, 17 and 2t) are top face filling picks, and

picks

2, 3, 6, .7 it), 11, 14, l5, l8 and 19 are bottom face filling picks.

As previously mentioned, the double weave construction of the present invention is characterized first by an arrangement of the warp in a 4l-14 pattern; that is, with each warp end a, b, c, d and e running alternately under a group of four top face and one bottom face filling picks and over a group of one top face and four bottom face filling picks. This warp arrangement is illustrated in FIG. 2 of the drawings in which the group of five warp ends and each of the bottomface filling picks being tied-in above a different warp end in running arrangement of each warp end a, b, c, d and e is separately represented in schematic fashion based on the pattern chart of FIG. 1. FIG. 3 further illustrates the fillingwise arrangement of the repeating groups of adjacent warp ends a, b, c, d and e to indicate the nature of the resulting weave structure at a pair of bottom and top

face filling picks

19 and 20.

It has also been noted previously that while the above noted warp arrangement involves a relatively high Warp density, a majority of the warp is maintained in floating relation at each filling pick, and this feature of the double weave construction provided by the present invention is demonstrated in FIG. 3 in which it will be seen that any five adjacent 'warp' ends are disposed l-up in relation to any top face filling pick (such as 20), l-down in relation to any bottom face filling pick (such as 19), and three ends floating in relation to all filling picks (such as 19 and 20), so that the floating warp exceeds the tying-down Warp by 50%.

As a result of this arrangement, the warp density in the weave construction of the present invention may be increased in the order of 25%, while still avoiding the boardiness that usually results from increased warp density, by maintaining a majority of the warp floating in the above noted manner. A further result of this preponderant floating arrangement in the warp is to allow a substantial reduction in the filling pick count so as to obtain a lightweight weave construction while at the same time disposing the filling at the opposite faces of the double weave for effective napping without difiiculty with bleeding through of the different colored top and bottom face fillings to the opposite faces.

As a representative example, a reversible blanket may be formed advantageously according to the present invention with warp consisting of cotton yarn having a count of 20s/1 and using a 2/225 reed to provide an initial warp density of 45 ends per inch (that would become approximately 46 warp ends per inch off the loom, and 50 ends per inch in the finished blanket), and was a blended rayon filling having a count of 2.85s used at a pick count of. 33 picks per inch. The resulting blanket cloth forms a 3 lb. blanket, which indicates the lightweight construction possible according to the present invention, although the bulk and napping qualities of this lightweight blanket cloth are exceptional so as to provide a warm blanket structure despite the lightness of the weave construction and the substantially reduced filling pick count.

The present invention has been described in detail above for purposes of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims.

Iclaim:

1. A Woven blanket of double woven construction with the filling napped at both faces of the double Weave, said double woven construction having each 7 warp end running alternately under a group of four top face and one bottom face filling picks and over: a group of one top face and four bottom face filling picks; having any five adjacent Warp ends arranged l-upin relation to any top face filling pick, l-down inrelation to any bottom face filling pick, and three ends floating in relation to all filling picks, the three floating ends in each group of five adjacent warp ends providing a barrier for separation of the top face filling picks from the bottom face filling picks, each of the top face filling picks being tied-in below a different warp end in each each group of five warp ends. 2. A woven blanket of lightweight double woven construction with the filling napped at both faces of the double weave, said double woven construction having a relatively high warp density and a relatively high warp bulk but having each Warp end running alternately under a group of four top face and one bottom face filling picks and over a group of one top face and four bottom face fillings picks, and having any five adjacent warp ends arranged l-up in relation to any top face filling pick, l-down in relation to any bottom face filling pick, and three ends floating in relation to all filling picks, each of the top face filling picks being tied-in below a different warp end in each group of five warp ends and each of the bottom face filling picks being tied-in above a different warp end in each group of five warp ends, whereby the three floating ends in each group of five adjacent warp ends providing a barrier for separation of the top face filling picks from the bottom face filling picks and boardiness as a result of said relatively high warp density is avoided while allowing reduction of the filling pick count to obtain a lightweight weave construction in which the filling may be napped effectively.

3.
