坯布克重计算方法坯布规格190T涤塔夫68DX68D20筘*2穿*30梭门副165cm以上算法只实用与不加捻产品,算出来是米克重哦.当然不加捻产品算克重都可以套用.如果是织造厂算原料的用量,在纬的门副上至少+10CM.经不用加.一.原料用量计算定义:织一米坯布需经纬原料多少克。1.长纤类:经用量(g/m)=总经跟数×(D/9000)×1.1纬用量(g/m)=坯布纬密×上机门幅×(D/9000)×1.1或=成品纬密×成品门幅×(D/9000)×1.1注:1.1=1+10%,10%为织缩率+损耗,一般FDY取1.08,DTY取1.12例1涤塔夫上机门幅168cm17号筘3穿坯布纬密28根/cm(168×17#×3入)原料:63DFDY×63DFDY求:原料用量解:经用量=168×17×3×63/9000×1.08=64.77g/m纬用量=168×28×63/9000×1.08=35.56g/m即理论米克重=64.77+35.56=100g/m例2.75DFDY+100DDTY五枚缎12#×5入×16630根/cm求:原料用量解:经用量=12×5×166×75/9000×1.08=89.64g/m纬用量=30×166×100/9000×1.12=61.97g/m2.短纤类:经用量=0.64984×(经密/经线纱支)×门幅纬用量=0.64984×(纬密/纬线纱支)×门幅注:也可把短纤换算成长纤,用长纤公式来计算,D=5315/S例1.70D锦纶FDY×21S棉133×7259”,求:原料用量解:经用量=133×59×70/9000×1.08=65.91g/m纬用量=0.64984×72/21×59=131.4g/m例2.经:70D锦纶DTY+30D氨纶纬:30S棉+40D氨纶86×5859”求:原料用量及原料所占比例解:氨纶有个拉缩比,一般30D的氨纶按10-13D计算,40D按15-18D计算,拉缩比一般可取3,如40/3=13.33,按15-18算经用量锦纶=70×86×59/9000×1.12=44.2经用量氨纶=86×59×13/9000×1.1=8.06纬用量棉=58×59×5315/30/9000×1.1=74.1纬用量氨纶=58×59×18/9000×1.1=7.53总=44.2+8.06+74.1+7.53=133.89g/m氨纶比例=(8.06+7.53)/133.89=11.64%棉比例=74.1/133.89=55.36%锦纶比例=44.2/133.89=33%3.加捻类:经用量=总经根数×D/9000×1.1×(1+捻缩率)×(1+蒸缩率)纬用量=坯布纬密×上机门幅×D/9000×1.1×(1+捻缩率)×(1+蒸缩率)3.1捻缩率捻缩率=0.0038×(T/mm)×(T/mm)×DD的倍数以10D为基础40D-0.1→40/10-0.1=3.950D-0.2→50/10-0.2=4.860D-0.370D-0.4…120D-0.9→120/10-0.9=11.1130D及以上在120D倍数的基础上,每增加10D增加0.8如:150D→11.1+3×0.8=13.5例1.75DFDY22T/2S2Z,求:捻缩率解:捻缩率=0.0038×2.2×2.2×(75/10-0.5)=12.87%例2.150DDTY8T/2S2Z,求:捻缩率解:捻缩率=0.0038×0.8×0.8×(11.1+2.4)=3.28%3.2蒸缩率蒸缩率10T/cm以下不计,10-20T/cm为5%,20T/cm以上取6.5%例经:50D有光FDY10T/2S2Z纬:75DDTY+40D氨纶16T/2S2Z上机208×15#×5入30根/cm求:原料用量解:经用量=208×15×5×50×1.08/9000×[1+0.0038×1×(50/10-0.2)]×(1+5%)=100.07纬用量=208×30×1.12×(75+18)/9000[1+0.0038×1.6×1.6×(93/10-0.6)](1+5%)=82.18二.前道报价整浆并车间倒倍捻车间上浆费用涤纶FDY0.03-0.04元/并DTY0.04-0.05元/并锦纶FDY0.05-0.06元/并分批整经并数=总经根数/1680根1680为最大上排原料筒子数取整数(只入不舍)分条整经0.1-0.5元/米最大上排筒子数一般为800低弹网络丝直接上分条0.06-0.1元/米例.经70D锦纶FDY168×70#×2入,求:上浆费解:168×70×2/1680=4并4并×0.05=0.2元/米加捻费用300元/吨.捻特殊600元/吨.捻300元/吨.捻=0.0003元/g.捻捻费=加捻丝的用量(g)×捻度(T/cm)×0.0003元/g.捻例.雪纺经:75DFDY20T/2S2Z纬:75DFDY20T/2S2Z19#×2入×175cm28根/cm求:捻费解:原料用量=175×(19×2+28)×75/9000×1.08[1+0.0038×2×2×(75/10-0.5)]×(1+6.5%)=122.5g/m捻费=122.5×20×0.0003=0.735元三.织造报价织造报价=坯布纬密×织造费(元/梭)织造费用与品种的织造难易程度和织机有关。喷水产品织造费用参考1.涤塔夫,春亚纺等170T,180T,190T210T0.01-0.015元/梭240T,260T,290T,310T0.015-0.025元/梭370T,380T,390T,400T0.025-0.035元/梭消光比半光品种高0.005元/梭2.桃皮绒,花瑶,色丁等0.02-0.03元/梭(加密品种加0.01元/梭)循环大,强捻,弹力品种0.03-0.05元/梭喷气品种织造费用参考锦棉,棉锦等0.05元/梭(经纬线粗的或加密的另加0.01-0.02元/梭)金属丝布,双层布0.0-0.2元/梭有梭织机品种织造费用参考平布,府绸0.02-0.03元/梭例1.170T涤塔夫61DFDY×61DFDY成品150cm166×17#×2入原料:1.4万/吨解:原料价格165/2.54×150×61/9000×1.08=71.33g/m71.33×0.014=1元/m注:由于竞争激烈,170T涤塔夫市场上一般不到170,只有165。前道价格166×17×2/1680=3.4即4并4×0.03=0.12元/m织造价格按0.01算则26×0.01=0.26元/m按0.015算则26×0.015=0.39元/m坯布价格=1+0.12+0.26=1.38元/m或=1+0.12+0.39=1.51元/m例2.加捻色丁11760根经:75D有光FDY1.56万/吨纬:150DDTY16T/2S2Z1.38万/吨坯布纬密30根/cm坯布门幅:168cm解:原料价格11760×75/9000×1.08=105.84×1.56=1.651元/m168×30×150/9000×1.1×(1+0.0038×1.6×1.6×13.5)(1+5%)=109.76109.76×1.38=1.515元/m前道价格上浆11760/1680=7并7×0.03=0.21元/m捻费109.76×16×0.0003=0.527元/m织造价格0.025×30=0.75元/m坯布价格=1.651+1.515+0.527+0.75=4.44元/m例3.锦棉金属布经:70D锦纶FDY2.8万/吨纬:甲32S2.2万/吨乙32S+68D金属丝11万/吨158×7659”3甲1乙解:原料价格经=158×59×70/9000×1.08=78.3g/m78.3×0.028=2.19元/m纬甲=0.64984×76/32×59×3/4=68.3g/m68.3×0.002=1.5元/m乙=68.3/3=22.76g/m68/9000×76×59×1.1×1/4=9.32g/m(22.76+9.32)×0.11=3.53元/m前道价格158×59/1680=5.55即6并6×0.6=0.36元/并织造价格5.9/2.54=29.9229.92/1.05=28.5梭28.5×0.13=3.71元/m坯布价格=2.19+1.5+3.53+0.36+3.71=11.29元/m开票价=11.29×1.05=11.85元/m
