DIAPER CONTOURED BY SHRINKING Filed April 27, 1964 2 Sheets-Sheet 23 gt l WARPW SE- Q] bA o' INVENTORZ NORMAN L. SELTZER J BWM MW' ATTORNEYS United States Patent 3,339,548 DIAPER CONTOURED BY SHRINKING Norman L. Seltzer, Princeton, N.J., assignor to The Kendall Company, Boston, Mass, a corporation of Massachusetts Filed Apr. 27, 1964, Ser. No. 362,785 16 Claims. (Cl. 128284) The present invention relates to diapers and more particularly to diapers which are contoured along side edges thereof to provide a better and more comfortable fit for a wearer. Still more particularly, the present invention relates to such contour diapers which have substantial lateral stretchability and recoverability.

Diapers have been formed for many years from sheets of fabric material of either single layer or multi-layer construction by folding these sheets into a rectangular configuration. In certain diapers, normally referred to as prefold diapers and which are becoming increasingly popular, the folded fabric is secured in the rectangular configuration by stitching the layers thereof together. Such conventional diapers are relatively inexpensive to manufacture, have high absorptive capacity, easy cleanability and various other well-known desirable characteristics.

However, when such conventional diapers are applied to infants, the medial portions thereof lie between the infants legs and the Width of the diaper material in these medial portions tends to spread the legs of the infants into unnatural positions. Also, such conventional diapers become greatly wrinkled or puckered in their medial portions when being worn, which wrinkles or puckers are a source of irritation to the wearers and are subject to excessive wear.

Various attempts have been made to solve the problems encountered in the use of such conventional diapers, but all of these attempts have been unsuccessful. One example of such an attempt is a contour diaper formed by cutting, folding and stitching the diaper fabric in such a manner that the side edge portions of the diaper have a concave configuration. This contour diaper, however, has several deficiencies, one of which is the irritation of the skin of the wearer by the sewn cut edges defining the contou-r areas. Another deficiency of this prior contour diaper is that the cutting, folding and sewing thereof is quite time consuming and laborious and, therefore, this diaper is considerably more expensive to manufacture than corresponding non-contour diapers.

Another example of a prior contour diaper is shown in United States Patent No. 2,866,459 to Sobelson and comprises a folded diaper which has transversely extending elastic stitching the medial portion thereof, which stitching was initially placed therein in a stretched condition, and then permitted to relax and draw in the side edges of the medial portion to impart a concve configuration thereto. However, this drawing in of the diaper material by the elastic stitching results in considerable wrinkling of the diaper fabric which is undesirable since it irritates the wearer and is subject to excessive wear. Also, the elastic stitching becomes brittle and frequently breaks after only a few launderings of the diaper. Further, this elastic stitching is relatively expensive and the stitching operation is also time consuming and laborious and, hence, the resulting diaper is expensive.

With the foregoing in mind, it is an object of the present invention to provide a novel contour diaper having the desirable characteristics of conventional non-contour diapers of corresponding layer construction and wherein the aforementioned deficiencies of prior contour diapers are obviated.

Another object of the present invention is to provide a diaper which is so constructed that when the same is washed or laundered, as is usually done with new diapers A further object of the present invention is to provide a novel diaper of the character described which has substantial stretchability and recoverability laterally thereof for further enhancing the fit of the diaper on a wearer.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- FIGURE 1 is a plan view of a diaper according to the present invention in unfolded condition;

FIGURE 2 is a somewhat schematic sectional view taken substantially along line 22 in FIGURE 1;

FIGURE 3 is a plan view of the diaper in folded condition before shrinkage thereof;

FIGURE 4 is a plan view of the diaper shown in FIG- URE 3 after being shrunk;

FIGURE 5 is a plan view of another form of dia-per in unfolded condition and incorporating the features of the present invention;

FIGURE 6 is a perspective view of the diaper shown in FIGURE 5 in folded condition and before shrinkage ing longitudinally in a fillingwise direction between selvages 12 and 13 at opposite ends of diaper blank 10; a pair of elongate intermediate or pinning bar section or panels 14 and 15 disposed on opposite sides of and interwoven with medial section 11 and also extending between selvages 12 and 13; and a pair of elongate non-raveling or pinking bar sections or panels 16 and 17 disposed on opposite sides of and interwoven with pinning bar sections 14, 15 and defining opposite side edges of diaper blank 10.

Diaper blank 10 is formed of a fabric of interwoven sets of warp and filling yarns and which is preferably of m'ulti-layer construction to provide the desired absorbency and softness. In this respect, medial section 11 is preferably formed of three layers of fabric 20, 21 and 22 (FIG- URE 2) woven together at least at selvages 12 and 13 and at opposite sides of medial section 11 where the same is joined to pinning bar sections 14 and 15. Also, pinning bar sections 14 and 15 preferably comprise two layers of fabric 23, 24 and 25, 26, respectively, the layers of each pinning bar section being woven together at selvages 12 and 13 and to one side of medial section 11 and to one of the pinking bar sections 16 and 17. Pinking bar sections 16 and 17 are preferably of single layer construction and have the outer side edges thereof pinked to resist raveling.

Preferably, a band 27 of reinforcing warp yarns extends transversely of the central portion of diaper blank 10 and is interwoven with the sections thereof. Band 27 defines a fold area along which diaper blank 10 is adapted to be folded to superpose opposite halves thereof and to form an elongate folded diaper 30 (FIGURE 3) which is preferably secured to this folded condition by spaced lines of longitudinally extending stitching 31, 32.

It has been determined that the fabric forming diaper 30 can be woven in such a manner and of such warp and/or filling yarns that the aforesaid contour can be provided therein at no appreciable increase in the cost of manufacture thereof over conventional non-contour diapers of comparable layer construction, and also without any decrease in absorbency thereof, and without any material wrinkling or puckering of the fabric thereof. This contour is achieved by weaving the fabric so that at least the fabric layers forming medial section 11 of diaper 30 are shrinkable laterally of the diaper to reduce the width thereof and to drawn in opposite side edges thereof to impart a concave configuration thereto. This shrinkability in at least the medial section 11 of diaper 30 is preferably achieved by having at least those yarns, preferably the filling yarns, extending transversely of medial section 11 of water-swellable cellulosic material such that the fabric including the same shrinks in the direction of these yarns upon being subjected to a conventional washing or laundering process, which is usually done before new diapers are used to enhance the softness thereof. Also, such yarns, as originally woven into the fabric, have a high twist multiple within the range of 4.50 to 7.50 to enhance this shrinkability of the fabric. More preferably, these filling yarns are of cotton or high wet modulus rayon and have a twist multiple within the range of about 5.50 to about 6.75 for good shrinkage characteristics while still having good absorbency, softness and economic feasibility.

Preferably, all of the sections of diaper 30 are woven in the above set forth manner utilizing the same filling yarns throughout the diaper for economy in the manufacture thereof. Therefore, all sections of diaper 30 are shrinkable laterally thereof, but medial section 11 is woven so as to have greater shrinkability than the remaining sections thereof. This greater shrinkability in the layers of fabric in medial section 11 is provided by each of these fabric layers 20, 21, 22, as originally woven, having less yarn interlacings per inch than each of the fabric layers 23, 24, and 25, 26 of pinning bar sections 14 and 15, and the single layer of each of the pinking bar sections 16, 17, as originally woven. In addition, the pinning bar sections or panels are preferably woven with less yarn interlacings per inch than the pinking bar sections or panels for greater shrinkability therein.

In a plain weave construction, which is preferred for all sections of diaper 30, an example of a fabric construction providing these varied yarn interlacings per inch in the various sections of the diaper would be a fabric having a warp end count of 32 and filling pick count of 46 in each of the layers 20, 21, 2,2 of medial section or panel 11; a warp end count of 48 and filling pick count of 32 in each of the layers 23, 24, 25, 26 of the pinning bar sections or panels; and a warpend count of 96 and filling pick count of 64 in each of the pinking bar sections or panels 16, 17. It is noted that this fabric construction provides a greater total number of yarns in medial section 11 of the diaper than in the remaining sections for providing greater absorbency therein, where the same is most needed. It should be understood that this fabric construction is one example only and many fabric constructions within the purview of the foregoing description may be used without departing from the scope of the present invention.

However, such a fabric construction having progressively increasing interlacings per inch in the layers of fabric from the medial section outwardly to the pinking bar sections is particularly preferred since the same not only provides medial section or panel 11 with greater shrinkability than pinning bar sections or panels 14, 15, but also provides pinning bar sections or panels 14, 15 with greater shrinkability than pinking bar sections or panels 16, 17. Therefore, upon shrinking of diaper 30, a pronounced contour is provided therein, as is illustrated in FIGURE 4 which shows a diaper 30' in which the concave configuration imparted to opposite sides edges is readily seen.

While not necessary, the wrap yarns in the fabric of diaper 30 are also preferably of cellulose material, such as cotton or high wet modulus rayon, for absorbency and economic reasons. However, these warp yarns have a standard twist multiple providing lower twist therein than in the filling yarns to provide a softer fabric. Further, to enhance the contour effect imparted to diaper 30 upon washing thereof, the medial section 11 preferably has a dimension longitudinally of the diaper no greater than two-thirds of the overall length of the diaper. This assures that the greater shrinkage in the medial section of the diaper is provided in the portion thereof which will lie between the wearers legs, which is the portion of the diaper wherein the width of material is desired to be reduced, and avoids an undue or undesirable shortening of the waist encircling portion of the diaper.

After originally weaving the fabric of diaper 30 in the manner set forth above for providing the aforesaid contour therein, but before separating the same into diaper blanks 10, this fabric preferably is drawn warpwise through a caustic treating bath with no appreciable fillingwise tension therein. This caustic treatment increases the normal sinuosity of the filling yarns in the fabric to a degree such that the fabric has substantial stretchability and a high degree of inherent recoverability in the fillingwise direction. It is noted that this stretchability may be characterized as easy stretchability wherein a relatively small force will cause the fabric to stretch as compared with prior stretchable fabrics having elastomeric or rubber yarns therein, and also, this inherent recoverability is also slower or easier than in such prior stretchable fabrics which is desirable for comfort to a wearer.

Therefore, diaper 30 formed therefrom has substantial lateral stretchability and recoverability which, for example, readily permits distention .and contraction of the badys abdomen without binding or becoming undesirably loose and, hence, provides a better and more comfortable fit for a wearer of the diaper. It is further to be noted that the lateral shrinking of diaper 30 upon laundering thereof to impart the aforesaid contour thereto, enhances the sinuosity of the filling yarns, and hence, the lateral stretchability of the diaper, by causing these yarns to recover from an elongated or stretched condition if the same have not previously recovered therefrom.

Referring now to FIGURES 5-9 of the drawings, there is shown another form of diaper, generally indicated at 40, which is formed in similar manner to diaper 30 to be shrinkable to provide the aforesaid contour therein and to have substantial stretchability and recoverability for the reasons set forth above. Diaper 40 differs from diaper 30 primarily in the layer construction of the fabric and the manner of folding the same to form the diaper. In this regard, a diaper blank 41 (FIGURE 5) is provided which includes an elongate medial section or panel 42 preferably extending longitudinally between selvages 43, 44; and elongate intermediate sections or panels 45, 46 on opposite sides of and interwoven with the medial section 42 and likewise extending between selvages 43, 44.

As illustrated in FIGURES 7 and 8, medial section 42 is preferably of two-layer fabric construction throughout, and intermediate sections 45, 46 are preferably of single layer construction throughout. Preferably, a pair of spaced bands 47, 50 (FIGURE 5) of reinforcing Warp yarns extend transversely of and are interwoven with the sections of diaper blank 41. Bands 47, 50 define fold areas along with diaper blank 41 is adapted to be folded to form diaper 40, in which bands 47, 50 define reinforced side edges and the medial and intermediate sections extend laterally between these reinforced side edges.

This folding of diaper blank 41 to form diaper 40 provides therein a longitudinally extending central portion which comprises three superposed two-layer portions 51, 52 and 53 (FIGURE 7) in medial section 42 and three superimposed single layer portions, 54, 55 and 56 (FIG- URE 8) in each of the intermediate sections 45, 46. Also, longitudinally extending side portions of diaper 40 are provided on opposite sides of the aforementioned central portion and each comprises a pair of superposed twolayer portions 60, 61 (FIGURE 7) in medial section 42, and a pair of superposed single layer portions 62, 63 (FIGURE 8) in each of the intermediate sections 45, 46. Diaper 40 is preferably secured in this folded condition by spaced lines of stitching 64,65 extending longitudinally of and adjacent the sides of the central portion thereof and by overedge stitching 66, 67 across opposite ends thereof, which overedge stitching also prevent raveling and define non-raveling end sections.

As was the case with diaper 30, the fabric forming diaper 40 is originally woven to be shrinkable with greater shrinkability in medial section 42 than in intermediate sections 45, 46 and non-raveling end sections 66, 67. The differential shrinkability is preferably provided in the same manner as in diaper 30 as described above and, hence, this description will not be repeated. Also, diaper 40 has substantial stretchability and recoverability laterally thereof which is also provided therein in the same manner as described above in connection with diaper 30. Therefore, when diaper 40 is laundered in conventional manner, the fabric thereof will shrink with medial section 42 shrinking a greater amount later-ally of diaper 40 than intermediate sections 45, and 46 and non-raveling end sections 66, 67. This shrinkage is accomplished without appreciable increased cost, without reduced the absorbency thereof, and without material wrinkling or puckering of the fabric.

Such a shrunken diaper 40' is illustrated in FIGURE 9 and it is readily apparent that the reinforced side edges 47', 50 thereof have a concave configuration imparted thereto. As with diaper 30, medial section 42 preferably has a dimension longitudinally of diaper 40 no greater than two-thirds of the-overall length of the diaper to enhance the contour effect imparted thereto.

It will therefore be apparent that the present invention provides novel stretchable contour diapers having the desirable characteristics of conventional non-contour diapers, but wherein the width of material in the medial sections thereof is reduced without reducing the absorbency thereof, without material wrinkling or puckering of the fabric therein, and without materially increasing the cost of manufacture thereof.
