CAD /CAM INTERGRATION FOR TEXTILE INDUSTRY

INTRODUCTIONTHE DEMONSTRATED BENEFITS OF CAD

INCLUDE “ INCREASED PRODUCTIVITY ,REDUCED PRODUCT DEVELOPMENT TIME ,INCREASED CREATIVITY TO IMPROVE CONCEPTIONAL DESIGNS,HIGH PRODUCT DESIGN CAPABILITY,REDUCED COST OF SAMPLES AND PROTOTYPES & REDUCED TURNOVER TIME

THE NATIONAL KNITWEAR ASSOCIATION CONDUCTED A SURVERY OF 228 APPAREL MANUFACTURERS WHICH INDICATED THAT.

IN CONTINUATION65% USE CAD TO CREATE COLORWAYS.60% USE CAD TO CREATE PRINTED FABRIC

DESIGN.48% USE CAD TO CREATE

MERCHANDISING PRESENTATIONS.41% USE CAD TO CREATE KNIT DESIGNS.

ROLE OF CAD IN TEXTILE DESIGNINGDESIGNERS CAN EXPLORE A MYRAID OF

VISUAL POSSIBILITIES WITHOUT THE COST OF MAKING SAMPLES OR STRIKE OFFS.COMPUTER CAPACITIES OFFER IMMEDIATE RESPONSE AND GRATIFICATION .FINALLY ,CAD HAS THE POTENTIAL TO CREATE SEAMLESS AND UNIVERSALLY UNDERSTOOD COMMUNICATIONS AMONG ALL PHASES OF OPERATION ,A CAPACITY THAT CAN SAVE MANUFACTURERS A GREAT DEAL

OF TIME & MONEY.

IN CONTINUATIONTHE ROLE OF COMPUTERS IN THE TEXTILE

AND APPAREL INDUSTRIES NO DOUBT CONTINUE TO GROW.ONE OF THE GREAT ADVANTAGES TO THE DESIGNER IN USING A COMPUTER IS THAT SO MANY MORE IDEAS CAN BE EXPRESSED THAN THE DESIGNER WOULD HAVE TO ACCOMPLISH BY HAND.ALL OF THIS MEANS THAT DESIGN CHOICES AND POSSIBILITIES CANBE INFINITE IF THE DESIGNER IS GIVEN THE TIME AND FREEDOM TO BE CREATIVE AND TO EXPERIMENT

USING THE COMPUTER SYSTEM.

IN CONTINUATIONCOMPUTERS SIMPLY AID IN THE PROCESS

:THEY SERVE AS TOOLS FOR DESIGNERS ,PATTERN MAKERS, AND SO ON.WHEN COMBINED WITH FINE SKILLS AND SENSIBILITIES ,THE COMPUTER HELPS PROFESSIONAL IN THE APPAREL INDUSTRY ACHIEVE BEAUTIFUL,SALEABLE CLOTHING.THE BENEFITS ARE NUMEROUS-SPEED,ACCURECY,PRODUCTIVITY,COMMUNICATION & SO ON.

TEXTILE DESIGN SYSTEMSSYSTEMS FOR THE DESIGN OF WOVEN TEXTILES

ARE USED BY DESIGNERS AND MERCHANDISERS IN MANY DIFFERENT MARKETS FROM FABRICS FOR HOME FURNISHING TO MENS-WOMENS-AND CHILDRENSWEAR.MOST FABRICS ,WHERE YARN DYES,PLAIN WEAVES,JACQUARDS,OR DOBBIES, ARE DESIGNED USING A CAD SYSTEM FOR TEXTILES.PRINTED OR EMBROIDERED ARE ALSO DEVELOPED AT CAD WORK STATIONS.IN MOST MARKETS,WHEREVER THERE ARE TEXTILES, A COMPUTER –AIDED DESIGN SYSTEM HAD SOMETHING TO DO WITH THE PRODUCT.

IN CONTINUATIONSOME TEXTILE DESIGN PROGRAMMES

CONTAIN ALL THE TECHNICAL INFORMATION REQUIRED FOR WEAVING, OR THE ENTIRE MANUFACTURING PLAN,INCLUDING THE YARN TYPE AND SIZE AND THE NUMBER OF ENDS AND PICKS FOR THE DESIGNATED WEAVE.

CHECKS & STRIPES WEAVE

KNITTED FABRICSTEXTILE DESIGNING SOFTWARE IS ALSO USED TO

CREATE AND MODIFY ALL TYPES OF KNITTED FABRICS AND GARMENT PARTS.SOME SYSTEMS SPECIALIZE IN KNITWEAR PRODUTION AND THE

FINAL KNITTED FABRIC DESIGN CAN BE VIEWED ON SCREEN WITH INDICATIONS OF ALL STITCH INFORMATION.THE FABRIC FOR CUT AND SEW GARMENTS OR THE COMPLETE GARMENT FOR FULL FASHIONED PIECES CAN QUICKLY BE GRAPHED BASED ON MACHINE GAUGE AND THEN CONNECTED TO A KNITTING MACHINE FOR PRODUCTION.A CAD KNIT PROGRMME WILL PRODUCE A SWEATER GRAPH

KNITTED SWATCHESTHAT WILL ALSO INCLUDE INFORMATION

INDICATING THE AMOUNT OF YARN NEEDED BY COLOUR FOR EACH TOP,SWEATER AND SO ON.

PRITED FABRICSWHEN PRINTS ARE CREATED,EITHER FOR

WOVENS OR KNITS,THE PROCESS USUALLY BEGINS WITH EITHER ORIGINALSCANNED ,OR VIDEO INPUT ARTWORK.THE DESIGNING INVLOVES THE DEVELOPMENT AND MANIPULATION OF A MOTIF.THE MOTIF CAN BE

RESIZED,RE-COLOURED ,ROTATED OR MULTIPLIED DEPENDING ON THE DESIGNER’S GOAL.THE ARRANGEMENT IS PUT

INTO A REPEAT WITH THE HELP OF THE COMPUTER.

IN CONTINUATIONTHIS IS SCANNED INTO THE COMPUTER &

THEN THE COLOUR IS REDUCED.TEXTURES CAN BE INDICATED SO THAT THE PRINT OUT EITHER ON PAPER OR ON ACTUAL FABRIC LOOKS VERY MUCH AS THE FINAL PRODUCT .THE TEXTILE DESIGN SYTEM CAN THEN SHOW COLOURWAYS IN AN INSTANT, RATHER THAN TAKING HOURS.

TECHNICAL SYSTEMS ALLOW ENGRAVERS TO CREATE COLOR SEPRATIONS FROM THE CAD GENERATED IMAGE AND OUTPUT THEM RIGHT TO FILM FOR TEXTILE PRINTING PROCESS

YARN DYED FABRICYARN DYED FABRICS

(PLAIDS,STRIPES,TWEEDS,ETC)CAN BE CREATED ON SCREEN AND EXACT INDICATIONS OF YARN TYPE,COLOR & WEAVE STRUCTURE CAN BE FED INTO THE COMPUTER.NEW YARN TYPES CAN BE DESIGNED ALONG WITH NOVELTY WEAVES.MODIFICATIONS TO EXISTING PLAIDS AND STRIPES CAN BE MADE BY THE COMPUTER BY REPROPORTIONING VARIOUS ELEMENTS.ALL OF THE CHANGES CAN BE PRINTED OUT FOR VIEWING AND EDITING WHICH OFTEN ELIMINATES THE COSTS ASSOCIATED WITH

IN CONTINUATIONORDERING SAMPLES FROM THE MILL.SOPHISTICATED SYSTEMS THAT

GENERATE DOBBY AND JACQUARDY WEAVES HAV E EXISTED FOR MANY YEARS .TODAY’S SYSTEMS DRIVE WEAVING LOOMS AND PRODUCE EITHER SAMPLES OR YARDAGE FOR PRODUCTION.

ILLUSTRATION /SKETCHPAD SYSTEMSTHESE ARE GRAPHIC PROGRAMS THAT ALLOW

THE DESIGNER TO USE A PEN OR STYLUS ON AN ELECTRONIC PAD OR LARGE FORMAT OR TABLET.

DRAWINGS ARE FREE HAND IMAGES WHICH ARE THEN STORED IN THE COMPUTER.THE TENDENCY IN CURRENT TECHNOLOGY IS TO SIMULATE THE ILLUSTRATOR’S TACTILE DRAWING EXPERIENCE AS MUCH AS POSSIBLE

BY PROVIDING A LARGE WORKING AREA & BRUSH STROKES THAT OFFER SENSITIVITY TO

IN CONTINUATIONPRESSURE & SIMULATED LINE QUALITY.IN

THIS WAY , A DESIGNER CAN PRODUCE STYLIZED ILLUSTRATIONS THAT ARE SIMILAR TO THOSE

DRAWN ON PAPER WITH A PEN OR MARKER.SKETCH PAD SYSTEMS ALSO HELP TO PRODUCE FLAT LINE RENDERINGS AND TECHNICAL DRAWINGS OF NEW DESIGNS.INTIALLY THE DESIGNER MAY DEVELOP A PERSONAL LIBRARY BY SCANNING FLAT DRAWINGS INTO THE COMPUTER & THEN MANUPLATING THEM.

IN CONTINUATIONFLATS & ILLUSTRATIONS CAN BE FILLED

WITH FABRIC DESIGNED ON A TEXTILE DESIGN SYSTEM.THESE SYSTEMS CAN BE USED TO DEVELOP STORYBOARDS,LINE PRESENTATIONS & OTHER SALES & COMMUNICATIONS TOOLS.

TEXTURE MAPPING & DRAPING SOFTWARETHIS TECHNOLOGY ALLOWS FOR THE

VISUALIZATION OF FABRIC ON A BODY.TEXTURE MAPPING IS THE PROCESS BY WHICH FABRIC CAN BE DRAPED OVER A FORM IN A REALISTIC WAY.THIS MEANS FOR EG:THAT IF THE FABRIC IS A STRIPE ,THE MAPPING WILL PRODUCE AN IMAGE IN WHICH THE STRIPE CURVES AROUND THE BODY,OR BENDS WITH THE ELBOW,OR ROLLS OVER THE FLARE OF A SKIRT.

IF A NEW GARMENT CAN BE SIMULATED ON SCREEN IN MINUTES,THEN THE TIME CONSUMING TASK OF

IN CONTINUATIONDEVELOPING SAMPLES IS GREATLY

REDUCED.CATALOGUES & BROUCHERS ALONG WITH MANY OTHER TYPES OF SALES,ADVERTISING & MARKETING TOOLS CAN BE DEVELOPED WITHOUT INVESTING IN SAMPLE MAKING,HIRING MODELS & TAKING PHOTOGRAPHS.

IN THIS WAY ,WE ARE ABLE TO TEST CONSUMERS RESPONSE TO A PRODUCT WITHOUT EVEN HAVING CREATED A “REAL” SAMPLE.

CONCLUSIONTHE TEXTILE INDUSTRY HAS MADE MAJOR

PROGRESS IN PROCESS MODERIZATION AND AUTOMATION OVER THE LAST 5-10 YEARS.

THE FOCUS OF THESE PROGRAMMES HAS BEEN IN ONE OF SEVERAL DIRECTIONS IN DIFFERENT COMPANIES.DUE TO THE INFLUENCE OF CAD THE PROCESS IMPROVEMENTS HAS TOUCHED GREATER HEIGHTS.THE ISSUES IN YARN FORMATION GENERALLY POINT FORWARDS TO REDUCING THE NUMBER OF STEPS WHEREEVER POSSIBLE.

IN CONTINUATIONIN GENERAL THE IDEAL YARN

MANUFACTURING PROCESS WOULD TAKE FIBRE FROM A BALE, & MOVE IT TO A SPINNING PROCESS FOR INSTANCE OPEN END SPINNING WITH AUTOMATIC TRANSFER OF THE YARN OUTPUT EITHER TO A WARP BEAM OR TO A LOOM.
