AND A FABRIC PRODUCED THEREBY
Abstract of the Disclosure An absorbent stretch fabric is provided by a novel warp knit structure. The fabric can be produced on any conventional warp knitting machine of the type having a plurality of guide bars by tying in a stretch yarn to the guide bar closest to the knitting needles, and by tying in an absorbent yarn to one of the other guide bars.
Description
``` 1047782 Specification _ _ T~is invention relates to a method of warp knitting and to a warp knit fabric produced therebyO
In the apparel lndustry, garments ex~ibiting both hlgh moisture regain and high ~tretch are in great demand.
For instance, undergarment6 and leieure garments (such as golf and tennis outfits) must provide the wearer with suitable ela~ticlty 80 that the wsarer' 9 mobility will not be unduly hampered. At the same time, however, the garment must be hlghly absorbent 80 that the wearer will not feel discomfort due to unabsorbed perspiration.
Heretofore, fabric producers have not been able to inexpensively produce absorbent stretch fabrics. Woven fabrics have alway~ been limited because of their slow production rates. Also, the inherent elasticity of a woven fabric cannot compare with that of knit goods. Weft knit fabrics sometimes lack the dimensional stability needed to withstand repeated launderings, and they are still not as inexpenslve to produce as warp knit fabrics.
Accordingly, lt is an ob~ect of the present invention to provide an ab~orbent ~tretch fabric and a method for producing such fabricO
It is a apecific ob~ect to provlde such a method that i8 characterized by relatlvely high production rates, thus provlding a fairly inexpensive fabric.
Further, lt is an ob~ect to produce an improved ab~orbent stretch fabric that provides great com~ort and elasticity to the weaver.

These and other obJects are met by the novel method and fabric disclosed herein. Basically, the method can be used in con~unction wlth any conventional warp knlt machine as lo~g as the knittlng machine is provlded wlth more than one yarn gulde barO The guide bar olosest to the knittlng needles is threaded with a stretch-type yarn. One of the other guide bars iB
then threaded wlth a yarn exhibltlng hlgh molature regaln properties. During knltting, loops of the absorbent yarn extend toward a first fabric side, while the loops formed from the stretch yarn extend toward the second side. Diagonally extending laps of absorbent yarn are formed on the second fabric slde, whlle dlagonally extending laps o~ the stretch yarn run along the first fabric side.
Preferably, the fabric i9 produced on a two bar warp knit machine.
The inventlon will be further understood by reference to the accompanying drawings and detailed descrlptlon of the preferred embodlments. In the drawings:
Figure l ls a stitch loop diagram on an enlarged scale of one embodlment of the novel warp knit construction;
Fi~ure 2(A) 18 a polnt dlagram, lndlcating the lapping movements of the guide bars needed to produce the ~abric shown ln Figure l;
Fl~ure 2(B) is a polnt diagram of another embodi-ment o~ the invention;
Flgure 3 is a perspective view showing the relation between the gulde bars, guides, needles, and needle bar, and also depicting the manner ln which the guides are threaded;

Figure 4(B) 18 a cutaway top vlew of a needle wlth yarns-lapped therearound, the entire beard portion of the needle cut away for simpliflcation.
Wlth reference to the drawing~ and especially to Figure 3, there 18 shown the knittln~ area of a conven-tional two guide bar warp knitting machine. The inventlon can be fully practiced on any standard warp knit machine having at least two guide bars. For example, the Reading BL~2 tricot machine, manufactured by the Textile Machlnery Dlvi~lon o~ North American Rockwell Corp., Reading, PennsylYania, wlll pro~ide optional results.
Guide bar~ 2, 4, have vertically mounted elongated 6uides 2(a), 4(a), re~pecti~ely, depending therefrom.
The ends of the guides are provided with eyes, ao that yarn ¢an be threaded therethrou~hO -As ls ¢on~entional in the art, euide bar 2 will be ~ub~equently referred to as the front bar, and guide bar 4 wlll be subsequently referred to as the back bar.
As can be seen ln Figure ~, the back bar 18 closer to the needle6 than is the front bar~
Xnltting needles 6 are reciprocally mounted ln needle bar 8 80 that they may be raciprocated vertically (upwardly and downwardly) during the knitting cycle in a manner well known in the artO
The normal knitting cycle and other warp knitting concepts such as point diagrams and chain arrangement~
for the guide bars, are explained in detail in "Warp Knitting Technology", by D.F. Paling, Columbine Press, second edition, reprinted 19700 . - . -. ~ .
Basically, a knltted loop 19 formed when yarn lapped about the bearded portion of the needle moves upwardly over yarn captured withln the needle beard.
This motlon is commonly referred to as "knock-over".
As 19 conventional ln the warp knltting art, the guide bars may swlng backwardly (to backslde 3 of needle bar 9) and forwardly (to frontslde lO of neelde bar 9).
Also the gulde bars can be moved in an endwise or lateral manner (parallel to the nzedle~). Lateral movemsnt of a guide bar in front of the needles is referred to as underlap, whereas lateral movement of the guide bar~
behind the needles (on the beard side) is referred to as overlap. The lateral movement of the guide bars controls the knltted stltch pattern. Ina~much as all of the guides on any one guide bar move as a unit, the lateral movements of any single guide can be recordsd as the stltch pattern. Pattern wheels or chain l~nks cause the guide bar to traverse the desired number of needle6. me pattern wheel or chaln link engages a pattern whe~l roller or chain link follow~r that are connscted to a gulde lever or gulde rocker arm, thu~
transmlttlng rotation of the pattern wheel or chaln to the de~ired lateral movement of the guide bar a~ 18 well known ln the warp knltting art.
As can be ~esn in Flgure 3, stretch~type yarn Ll 18 tled lnto the back guide bar, and absorbent yarn L2 i~ tied lnto the front bar. As the yarns are placed around the needles after overlapping, lt will be apparent that yarn Ll will more closely implnge the needle shaft than doe~ yarn L2.
- ~ .
It will be apparent that slnce aach guide i8 threaded, each needle will be provlded with two yarns after the overlapping movements of the guide bars. Thus, due to the novel ~ethod of tying an absorbent yarn into the front bar and tying a stretch yarn into the back bar, a fabric will be produced where loops composed of the - absorbent yarn wlll extend toward a first fabric side, while loops of the stretch yarn will extend toward the second fabrlc side.
Figure 4(A) illustrates the manner in which the yarns are lapped about the needle. In this Figure, part of the needle beard has been cut away. It can be seen that if the yarns are captured in the needle beard, yarns passing along the needle shaft that slide over the bear will form knitted loops. ~gain, see the Paling textbook for a full explanation of the conventional knitting cycle.
Figure 4(B) is a top cutaway view illustrating the fact that stretch-type yarn ~ more closely impinges the needle shaft than does absorbent yarn L2.
Figure 2(A) i8 a point diaEram illustrative of the lapping paterns of the front and back gulde bar that are necessary to produce the fabric shown in Figure 1.
To produce the lapplng movements shown in Figure 2(A), the chain or pattern whael controlling the ~uide bar must con3i~t of links or steps arranged in a certain manner so as to properly engage the guide bar push-rod or lever.
The chaln arrangement for the front bar iB determined by viewlng the dotted line, while the solid line represents ~0 the back bar, Thus, the chain arrangement of the front bar is 1-0/1-2, and repeat. The chain arrangement for the back bar 18 1-2/l~0, and repeat~

~C)47782 Flgure 2(B) shows another point diagram illustrating yet another guide bar lapplng pattern that wlll produce an lmproved ab~orbent ~tretch fabric. The chain arrange-ment of the front bar again is determined by viewing the dotted line, and the back bar arrangement i~ determined by viewing the solid line. Here the chain arrangement of the front bar is 1-0/1~2, and repeat. The chaln arrangement of the back bar is 2-3/1-0, and repeat.
Figure 1 i8 an enlarged stitch loop diagram of the fabric produced when: absorbent yarn L2 i8 threaded into the front ~uide bar, stretch yarn ~ i8 threaded into the back guide bar, and the chain arrangements shown in Figure 2(A) are used. It is apparent that loops 12 of absorbent yarn L2 axtend toward a first fabrlc side, while loop~ 14 of stretch yarn ~ extend toward the æecond f~abr~c side. Note also that the lapping motion produces diagonally extending laps that run from wale to wale.
Lap~ 16 of absorbent yarn L2 run along the second fabric side. In combination, the loops and laps of absorbent yarn substantially envelop the stretch yarn ln the fabric.
Laps 18 of stretch yarn ~ run along the ~irst fabric side.
I have found that when yarns spun on the woolen, worsted, or cotton systems are used a~ absorbent yarns in accordance with the invention, enhanced results are created~ For instance, cotton, wool, and hi~h wet modulus rayon yarns ha~e been optimally knitted with ~tretch yarns to form stretchable yet hlghly comfortable absorbent fabricsO
~0 ~uitable 8tretch yarns to be e~ployed may include ~ynthetlc yarna formed from polyesters, polyamides, acryllcs, etcetera.

Also, the corespun type of elastomerlc yarn, characterlzed by havlng an elastomerlc filament core surrounded by staple fibers that have been twlsted about the fllament's axls, can also be advantageously employed as stretch yarn8 - -ln accordan¢e with the lnventlon.
It wlll become apparent that a myrlad of possible combinatlons of yarn selectlon and lapping sequences can be employed in practicing the inventlon, all falling within the scope and spirit of the appended claims.
