NON-WOVEN FAB~IC ~qADE FROM P:)LYBUTADIENE
The present invention relates to a non-woven fabric comprising an assembly of fibers of discrete length which are interconnected and, at least a portion of which are in contact with other, said 5 fibers comprising crystalline syndiotactic 1,2-polybutadiene (1,2 SBD) .
Presently non-woven fabrics are used for a variet~ of applica-tions such as,for covers for disposable diapers and other hygienic applicat;ons, decorative ~crims, fusible scrims for adhesive applica-10 tions, industrial fabrics such as backing fa~rics for carpet manufac-~uring, as a packag~ng fabric and as an insulating fa~ric, etc.
Presently polypropylene and 3ther thermoplastic polymers used for these applications by extruding and fibrilla~ing ~he film into a fibrous interconnected network. However, the polypropylene prod-15 ucts made using the aforesaid process do not have good elongati~nand elasticity, and as a result the fa~ric has a low tensile strength and in particular a low tear ~trength. O~her ~hermoplas~c polymer~
have ~imilar disadvantages and/or limitations in respect to ~kin irritation, moisture resistance, high melting point, air permeability, 20 etc.
In accordance with the present ~nvention a non-woven fabric made up of 1,2 S13D can be u~cilized for all of the applications noted abDve. A unique advantage of the present invention i~; ~he low modulus, high elonga~on and good recovery Df ~he 1,2 ~BD fibers, 25 resulting in a non-woven fa~ric having high ~trensth proper~des.
Other advantages in u~ing 1,2 SBD ~n a non-woverl fabric are the aesthetic appearance of the 1,2 SBD due to its li~ht transparence, ~ts non-to~c and non-skin ~lta~ng pr~perties, its low melffing p~int when u~ed i~ adhesive ~pplications, its ~ood pliabili~ hus 30 iEacilita~ s use in complicated ~onfigurations a~d its ~ood mois-aure resistance and ~ir permeatiDn when used in disposable diapers ~nd hygienic napkin applications.
The low mel~dng p~int ~f 1,2 SBD make it useful ~ f~er fQrm for adhesive applications since the polar nature ~1,2 SBD prom~tes 35 ~ood ~nterac~dorl with the ~dherin~ ~ubstrates. It ~s ~elt that because -of t~e ~reater nu~iber o~ ~inyl unsaturated ~roups ~n ~he ' ~t '" ,' :

A further useful method of preparation is the melt casting of the po]ymeric 1,2 SBD material intn unoriented fflm which is uniaxi-ally oriented In a hot-stretching zone and mechani~ally worked to produce the fibrillated product.
A more recent method ~or producing non-wov n fibrous net-works comprises extruding a mixture of a molten polymeric material and a foaming agent radially through a circular die, then applying itress with a substantial radial component to ~iaid molten polymeric material to attenuate thei extrudate and produce and attenuated ne~work upon extrusion from the die.
The extrudate is quenched to a temperature }~elow its melting point, and then ~tretched further in a direction with a substantial radial component to fo~n the non-woven fibrous network.
The following example is illustrative of the invention.
Crystalline syndiotactic 1,2-polybutadiene pelle$s having a melt index of 3 were dry blended with 1 peroent by weight of azodicar-bon~de blowing agent. The blended polymer was fed into $he hopper of a 3-inch diameter extruder, and passed through 2 radial die having a diameter of 13 inches. Starting from the die, which was maintained at 152C: (305F), ~he temperature zones of ~he extruder were con~rolled at 155-14Q-135-115~C.
. The extruded melt was cooled at a contr~led rate to ~elow the melting temperature, 80C (176~F)using two opposing air rinç~s.
The ~emperature ~f the air was adjusted at ~bout 24C (75F). The extrudate was then contacted a~ainst ~he ~urface of an electrically heated ring to heat the fibrous extrudate to a ~emperature of 88 ~o 99C (190 ~o 210~). The extruàate was then forced over ~he outside of a rin~, which was maintained ~t 7C (45~).
In passing over the cool ring, the cylindrical 1,2-SBD extru-date is biaxially Driented to an expansion ra~ of about 2:1 and the cry~talline ~trucn~re therefore oriented t3 a 6ubstantial degree.
The bia~ally oriented ex~udate was then ~ollapsed 1: y ~n internal spreadin~ ~uide to pr~duce a double layer, flat fabric ~tructure w~ich was pulled by a pair OI nip x~lls.
.
:~37Z~7 The fa~ric obtained was very fibrous, its weight was 0.3 oz/yd2 and it had a ~treng~h ratio of 5 to 1 (st~ip tensile machine direction/strip tensile transverse direction).
A quantity of this fabric was used successfully as a cover for disposable diapers. Another portion of this fabric was used as a fusible scr~m for the adhesion of polyurethane foam to synthetic cover upholstery fabrics.
