OUR PATENTED INVENTION IS PROTECTED BY NUMEROUS WORLDWIDE PATENTS INCLUDING USA # 5,707,720 DATED JANUARY 13, 1998 . IT PROVIDES A METHOD OF PREPARING A UNIQUE SIZING PRODUCT COMPRISING OF A REACTION PRODUCT OF STYRENE - BUTADIENE COPOLYMER GRAFTED INTO STARCH. THE STYRENE - BUTADIENE COPOLYMER IS MADE SOLUBLE THROUGH THIS REACTION. THE RESULT IS THE PENFLEX SERIES OF PRODUCTS.
PENFLEX DECREASES THE DEPENDENCY OF TEXTILE MILLS IN THE USE OF POLYVINYL ALCOHOL BY REPLACING PVA ON A KILO BY KILO BASIS FROM 40% TO 100% IN SIZING FORMULATIONS FOR SPUN YARNS. ACTUAL REPLACEMENT RATIOS DEPEND ON MILL SIZING AND WEAVING CONDITIONS IN ADDITION TO YARN QUALITY.
UNFINISHED FABRICS CONTAINING PVA BASED SIZING FORMULAS ARE NOT ACCEPTED BY MANY FINISHING MILLS DUE TO ENVIRONMENTAL REGULATIONS. [ DESIZING THESE FABRICS CAN LEAD TO SEVERE FINANCIAL PENALTIES.] THE PENFLEX SERIES OF PRODUCTS HAS SOLVED THIS PROBLEM. BY REPLACING PVA WITH PENFLEX, YOU WILL ACHIEVE HIGHER WEAVING EFFICIENCIES, A HIGHER PERCENTAGE OF GRADE A FABRICS AT A LOWER COST, AND REDUCTION IN DESIZING COSTS.
PENFLEX SERIES OF PRODUCTS CAN BE DELIVERED IN DIFFERENT VISCOSITIES. IT CAN BE MANUFACTURED TO MATCH THE VISCOSITY OF THE PVA TO BE REPLACED. IT IS COMPATIBLE WITH ALL STARCHES, WAXES, LUBRICANTS, ANTISTATIC AGENTS, HUMECTANTS, SURFACTANTS AND OTHER PRODUCTS NORMALLY USED IN SIZING FORMULAS.
PENFLEX ALSO CAN REPLACE ALL BINDERS COMMONLY USED IN SIZING FORMULAS SUCH AS CMC, ACRYLICS [BOTH LIQUIDS / POWDER], AND POLYESTER RESINS. PENFLEX SERIES CAN BE USED IN NATURAL, SYNTHETIC, OR BLENDED SPUN FIBERS, INCLUDING COTTON, WOOL, SILK, RAYONS, POLYESTERS, NYLONS, VISCOSE, AND ACETATE.
| PHYSICAL FORM | OFF WHITE POWDER, FREE FLOWING FORM |
| ODOR | SLIGHT STYRENE BUTADIENE COPOLYMER |
| PH [ 10% SOLUTION ] | 5.0 TO 8.0 |
| MOISTURE | 12% MAXIMUM |
| BROOKFIELD VISCOSITY | 30 – 60 CPS @ 8.5 % SOLIDS 87 DEGREES C |

PENFLEX PROVIDES GREAT IMPROVEMENT IN THE COATING OF THE YARN. ENCAPSULATION IS THE AMOUNT OF SIZE ON THE SURFACE OR THE OUTSIDE OF THE YARN. CONVENTIONAL SIZING PRODUCTS ONLY ENCAPSULATE APPROXIMATELY ONLY 270 DEGREES OF THE YARN SURFACE.
PENFLEX ENCAPSULATES APPROXIMATELY 360 DEGREES OF THE YARN SURFACE. THE EFFECT OF THIS COMPLETE ENCAPSULATION MEANS REDUCED SIZE AND FIBER SHEDDING DURING THE OPENING OF THE WARP SHEET AT THE FRONT OF THE SIZING MACHINE. THIS CREATES LOWER HAIRINESS AND RESULTS IN HIGHER WEAVING EFFICIENCIES.
PENFLEX , WHEN ADDED AS A PVA REPLACEMENT IN A STANDARD SIZE FORMULA, IMPROVES THE OVERALL PENETRATION OF THE SIZE IN THE YARN BUNDLE. THIS CONTRIBUTES TO A STRONGER YARN WITH REDUCED SHEDDING DURING SIZING AND WEAVING. REDUCED SHEDDING MEANS LESS YARN BREAKS AND BETTER FABRIC QUALITY.
IMPROVEMENTS IN BOTH ENCAPSULATION AND PENETRATION CAN BE CONFIRMED MICROSCOPICALLY.
DUE TO BETTER ENCAPSULATION AND PENETRATION, YARNS SIZED WITH PENFLEX IMPROVE FIBER LAY OR HAIRINESS WHICH PROVIDES LESS TENDENCY TO ADHERE OR CLING TO EACH OTHER DURING WEAVING , MAKING FOR A CLEAR OPENING BETWEEN THE WARP SHEETS THAT LEADS TO HIGHER EFFICIENCIES IN WEAVING AND BETTER FABRIC QUALITY.
PENFLEX SERIES ARE UNIQUE SIZING MATERIALS THAT CAN BE USED AS A DIRECT REPLACEMENT FOR PVA AND OTHER BINDERS IN THE SIZE FORMULA. THE BASIC RAW MATERIAL IS A STYRENE – BUTADIENE COPOLYMER.
BASED ON CUSTOMER REQUESTS, WE CAN INCORPORATE OTHER SIZING ADDITIVES IN THE PENFLEX EITHER ON A PERCENTAGE DECIDED BY THE CLIENT OR BASED ON OUR APPLICATIONS TECHNOLOGY. WE CAN INCORPORATE WAXES, LUBRICANTS, SOFTENERS, DEFOAMERS, ANTISTATIC AGENTS AND OTHER COMMONLY USED ADDITIVES IN THE PENFLEX.
PENFLEX PROVIDES EXCELLENT DESIZE PROPERTIES. OUR TECHNOLOGY MAKES THE STYRENE – BUTADIENE COPOLYMER REACTION PRODUCT EASILY REMOVED USING ONLY WATER AT TEMPERATURES ABOVE 90 DEGREES C. THE FINAL DESIZE RECIPE WOULD ALSO DEPEND OF THE DESIZABILITY OF THE OTHER CHEMICALS USED BY THE MILL IN THE SIZE FORMULA.
PENFLEX PRODUCTS ARE PACKED IN 25 KILO, PAPER BAGS SUITABLE FOR EXPORT. IT IS PREFERABLE TO STORE IN A DRY AREA.
PENFLEX SERIES COMPLY WITH THE TOXIC SUBSTANCES CONTROL ACT AND ARE MANUFACTURED UNDER 1SO-9002 CERTIFICATION IN AN ENVIRONMENTALLY SAFE FACILITY THAT SERVES AS A MODEL FOR OTHER OPERATIONS IN THE CHEMICAL INDUSTRY.
