corporation of New York Application October 10, 1939, Serial No. 298,760 2 Claims." (01. se -24) invention relates to a fabricmade upon a lace machine. I I

Y The object'of the invention is to produce a lace fabric which is, suitable for use in themanufacture of garments worn by women, for instance, I girdles or other foundation garments, or portions thereof, worn next to the skin, and is also suitable for stocking garter tops, elastic narrow fabrics, caps and other articles whereelastic materials could be' utilized The material of this invention is a combinationof alternate areas of clothing or closely woven portions and netting,

' providing stretch in both lengthwise and crosswise directions. The material, by reason of its peculiar construction, as will hereinafter appear, will fit or adjust itself to the form of the wearer, without exerting discomforting pressure.

In the drawing, Fig. 1 represents an enlarged plan view illustrating a portion of the complete,

fabric of this invention; Fig. 2 an enlarged detail of a section of the fabric under tension only crosswise of the warp threads, and Fig. 3 an enlarged detail of. the same section of -fabric under warp threads.

Thesection of lace fabric I comprises clothing portions 2 and netting portions 3. The clothing tensiononly inthe direction of the run of the portion 2 has its threads in' close relation, comparative to the relation of the netting portions 3, the latter exhibiting definite openings characteristic of net fabrics. The alternate portions'of clothing-and netting make up the whole'fabric.

The clothing portions may be formed in a predetermined design such as the petals of flowers, the spaces between the individual petals and individual flowers being joined by netting. [The material is made upon a lace machine in which a serie's of initiallyparallel cotton-wound elas tic or rubber threads l, 5 are arranged in. parallel relation and are connected together by a cotton tying or bobbin thread 6. The cotton-Wound elastic or'rubber threads,on the lace machine,

are'put under slight tension while. the tying thread is being twisted with respect thereto and by reason of the manner in which the tying thread ,6 is h'andled or manipulated the peculiar fabric of this invention is produced. Reference to Fig. 3 shows the relation of the

elastic threads

4 and 5 with respect to each other and the relation of the cotton tying thread 6 with respect to the elastic threads and also the manner in which n the tying thread 6 distorts the elastic threads. 'It is tobenoted that a tying thread 6 (see Fig. 3,

the top three threads I, 5, 4) in the section of the material comprising clothingv 2, passes under and over the top thread' 4, across (beneath) the thread 5, over and under the second thread 4,

across (over, but not around) the intermediate thread 5, and thence, inits courses, repeating such relation throughout the portions of the fabric which are comprised of clothing. The tying thread ii, whenit reaches the area of the netting. 2, -instead of embracing three warp.

threads, embraces but two, as is shown to the right of Fig. 3. It will benoted that the top course of the tying thread 5, in the area of the netting 3, passes across (beneath, but not around) the second thread 4, over and under the thread 5,0ver and under the second thread 4, then merely-over the thread j5,' under and over the top thread 3, under and over the thread 5, and

under and over the first thread 4, under the thread 5 and repeating this course throughout the netting area. Each'tying thread follows this same course throughout the fabric, forming the netting portions 3. I

It is to be'noted that the intermediate elastic threads 5, when the, material is stretched eitherin warp-wise direction (Fig. 3) or across the Warp (Fig.2), do not substantially change their straight course in the area of the clothing 2,'but merely stretch in the direction of the pull. The

threads in the area of the clothing, when the fabricfis pulled across the warp, (Fig. 2), take a sinuous position and when the fabric is pulled in the direction of the warp (Fig. 3) such threads 4 are substantially straight, whereas the intermediate threads 5 in the area of the clothing 2 in both directions remain substantially straight.- All the elastic threads in the area' of the netting,

when subjected to pull either in warp-wise direc-' tion or across the Warp, take sinuous positions.

fabric comprising elastic warp threads and non;

Actually, in the manufacture of the fabric, more elastic tying'threadssaidfabric being stretchable in the direction of the warp and across the warp,

each warp thread running continuously through the clothing and the netting portions and being tied together in said portions by the tying threads,

each tying thread being associated with three v elastic threads, in the clothingportion said tying threads progressively passing around the outer edge of said elastic threads and across the intermediate elastic thread and in the netting portion saiditying'thread passing progressively and'suoc'essively around the'intermediate thread and one of said outer threads, across Said intermediate thread and then around the other outer thread and said intermediate thread, said outer threads when the fabric is stretched across the warp taking a sinuous configuration in both the clothing and netting areas, 'said intermediatethreads in the clothing portion being substantially straight and sinuous in the netting portion.

A fabric, madev upon-a lace machine, comprising clothing and netting portions; elastic Warp threads and non-elastic tying threads, each alternate elastic Warp thread in the clothing por-r tions being tied together in pairs by the tying threads passing around the elastic warp threads, of each pair and across the elastic threads intermediate. each pair of elastic threads, the tying f threads in the netting portions passing aroundf an intermediate thread and one of the threads of such pair of threads, across theintermediate thread, aroundthe other thread ofsaid pairvof threads, around the intermediate thread and j around said other thread ofsaid pair of threads,
