GRO;I~:U or 1'U INVENTION
In ~he preparation o paper, woven support 5 bellts are used for the initial castirlg and subæequent txeatment of the paper. These belts are known as paper clo~hing~ ~ variet:y o materials has been used in the manufacture o~ such belts, incl-lding metals and, more recently, thermoplastic monofilaments and 10 multifilaments.
While paper-making belts of therm~plastic materials have provided al numb~r o~ advantages, paper clothing prQpared ~rom l~hermopla tic ma~erials c:ccasionally exhibi~s poor dimensional stability and 15 high water absorption. Various techn1qlles have been sugg~sted for the improvement of dimensional stabilit~, includirlg the use of thermoplastic mono:Ei1aments having different degr~es of orientation in ~he machine and tran~verse directions or the use 20 of multifilaments having exceptionally high modulus of elasticity. ~Iowever, previously sugges~ed ce~mbinations of materials and filam~nt configurations have no~ fully satisf ied ~he need for paper clothing having excellent dimensional stability and low water 25 absorption and which is easily cleaned after lon~-term operation.
The instant invention provides, in a woven, heat set, paper-making belt of mac:hine and ~ransverse 30 direc~ion thermoplastic filaments, the improvement wherein the filamerlts in at least one of the machine and transverse directions are coextruded mono~ilaments having a core of a polymer selec'ced from nylon 66; polyethylene ~rephthalate; and a 35 tetrapolymer of tere- and iso- phthalic acids, '7~
1,4-butane dlol, and po].ytetramethylene ether glycol and a sheath of a polymer selected from the group consisting of nylon 11; nylon 12; nylon 6; nylon 610;
nylon 612; polybutylene terephthalate; and a tetra-polymer of tere and iso- phthalic ac.ids, 1,4-butane diol, and polytetramethylene ether glycol wherein the shea-th is adhered to the core and has a melting po.int at least about 25 Celsius degrees lower than the core, and wherein the machine and transverse direction filaments are bonded together at the intersections of the filaments by the substance of at least one of the filaments.
DETAILED DESCRIPTION OF THE INVENTION
The monofilaments used in at least one direction in the woven structures of the present paper clothing are coextruded structures having a sheath and a core. These monofilaments are prepared by conventional coextrusion techniques, as described, for example, in U.S. Patent 2 936 482.
The materials which can be used for the core of the monofilaments include poly~examethylene adi-pamide (nylon 66), polyethylene terephthalate and a tetrapolymer of tere- and iso- phthalic acids, 1,4-butane diol and polytetramethylene ether glycol containing less than 50 weight percent of the resulting butane diol terephthalate.
Polymers which can be used for the sheath component of the monofilaments include polyundecanoamide (nylon 11), polydodecanoamide (nylon 12), polycaprolactam (nylon 6), polyhexamethylene decanoamide (610 nylon), polyhexamethylene dodecanoamide (nylon 612), polybutylene terephthalate, and a tetrapolymer of tere- and iso- phthalic acids, 1,4-butane diol and polytetramethylene ether glycol wherein the resulting butane diol terephthalate comprises about from 70 to 90 weight percent of a tetrapolymer.
The tetrapolymers of the terephthalic acids, polytetramethylene ether glycol, and l,~-butane diol which can be used for the core and the sheath can be prepared according to the teachings of Witsiepe, U.S.
Patents 3 651 014 and 3 763 109, respectively.
The sheath component of the monofilament must be adhered to the core. In this regard, certain com-binations of sheath and core polymers are well suited for the preparation of a monofilament charac-terized by excellent adhesive bonding between the sheath and core. These combinations include nylon 11 with either nylon 66 or polyethylene terephthalate; nylon 12 with either nylon 66 or polyethylene terephthalate; nylon 6 with nylon 66; nylon 610 with nylon 66; nylon 612 with either nylon 66 or polyethylene terephthalate;
the terephthalic acid tetrapolymers with each other or with polyethylene terephthalate; and polybutylene terephthalate with polyethylene terephthalate. The sheath material should be selected to provide a final structure in which the polymeric sheath has a melting point at least about 25 Celsius degrees below the melting point of the core polymer.
Particularly desirable combinations of polymers in the instant invention include a core of nylon 66 with a sheath of nylon 11, a core of nylon 66 with a sheath of nylon 612, and a core of either polyethylene terephthalate or the terephthalic acid terpolymer with a sheath of terephthalic acid tetrapolymer high in butane diol terephthalate.
The relative concentration o~ ~hea~h and core polymers in the monofilament c:an vary widely.
~lowever, to fully reali2e ~he benefit of relatively low water absorption hy ~he sheath polymer, it shollld 5 compr ise at leas~ about 5~ by weight e~f ~che monoilament, and can comprise up to about 50% of the total weight o the monofilament. For ease of operation, the sheath preferably comprises at least about 10% by weight of the monofil~mentO
After extrusion and quenching of the monofilaments, they should be c~riented about from 3.4 to 6. 0 times their ox iginal leng'ch, arld pre~erably abc:ut from 3~5 to 4.75 ~imes ~cheir original leng~ch to increase the mono ilament streng~h. The 15 mono:Eilamen'cs generally have D diameter of about ~rom 6 to 32 mils (0.15-0.81 millimeter~.
- The coextruded mono~ilaments c:~n be used in one or both of the machine and tran~verse dire tions oE the paper-makin~ belts. When used in only one 20 direction, it is preferred that ~he coextruded monofilaments make l~p the trarl~verse, or fill, dire~tion filaments. Other filaments which can be used for the machine~ or s~arp~ direction are i?olymeric homogenous monofilamen~ or multifilament.
25 Polymeric resins which can be used in SUCil filaments include poly(metaphenylene diamine isophthalamide), polye~hylene tereph~halate t nylon 6, nylon 66, polybutylene terephthalate, polyhexamethylene adipamide~ and polyacrylonitrile.
The filaments are woven into paper-making belts according to conventional weaving techni~ues.
The type and density of th~ weave will, of course, depend on the ~ype of paper and paper~making operation for which the belt is to be used. After . 35 weaving, the belts are heat set ~o stabilize ~he weave and fuse ~he mono~ilaments at their intersections by meltlng or so~tening of the shea1:h polymer o~ the coex~ruded monofilamen~s. The sheath polymQr will fuse to similar sheath polymers if a coextruded monofilament is used in both directions of the weave, or to the homogenous monof ilament or multifilament used in the machine direction of the weave. Specific conditions for such annealiny or ~using will, of course, va.ry wi.th the pol~rer, filament geometry and weave, but will typically involve heating under tension Por about from 15 minutes to 1 hour at a ~emperature o~ about from 150 to 235C. l'ypically a hot air oven or radiant h~aters are u~d Por the hea~ing. Fusion of the int:~rsections of the filaments ln this manner eli.minates ~he need for ~he immersion o~ a woven belt in a separa~e r~sin for stabilizing the wea-re. Re~in treatmen~ can, of cc)ur~e, be included ~r other puxposes, i~ desired.
2a The paper~making bel~s of ~he present invention exhibit excellent dimensional stability and performance characteristics. The core materials of the monoilaments provide the ~trength neces~ary for long-term operation of a paper-making belt while the lowex melting sheath compcnents not only fuse to sta~ e the weave of the bel~ but may also reduce the amount of water absorption by the belt in operation. Moreover, the monof ilamentary structure exhibi ts less t~ndency to pick up debr is in operation, and, when the belt does become fouled, it is eas ier to clean .
The present invention is fur~her illustrated by the following specif ic example .
EXAMPLE
Monofilament was melt ~xtruded on a coex~rusion apparatus with a core of nylon B6 and a ~heath of nylon 612, and ori0n~ed by ~'cret::hing about 5 4., ûX in a radiant oven at a temp~rature of 600C.
The filament was then relaxed in a sec~ond radiant oven at 600C to con~rol shrinkage. The oriented monofilamen~ had a diameter of 20 mil~.
P~ paper-making be L~ was woven using ~he 10 monofilamerlt in the fill or ~ransverse dire~tion.
The lc:~ngitudinal or machine direction ~ilamen~s were poly (methaphenylene diaminel i~ophthalamide) multifilaments of 1200 den~era Tlle filament~ in the woven be].~ were used at their intersection~ by lS heAting ~he belt to a temperature of 232~C ~o effect bonding. The resulting woven belts were evalua~ed and found ~o exhibit ou~standing perf~rmance character ~stics or paper --making operation~ .
