一平方米棉坯布无浆干燥重量

一平方米棉坯布无浆干燥重量计算方法1公式计算1.1一平方米棉坯布无浆干燥重量按下式计算：式中：G——一平方米棉坯布无浆干燥重量，单位为千克（kg）；GJ——一平方米棉坯布的经纱干燥重量，单位为千克（kg）；GW——一平方米棉坯布的纬纱干燥重量，单位为千克（kg）。式中：Pj——棉坯布的经纱密度，单位为根每10厘米（根/10cm）；gj——经纱纺出标准干燥重量，单位为克每百米（g/hm）；fj——经纱总飞花率，%；aj——经纱缩率，%；sjz——经纱总伸长率，%。式中：Pw——棉坯布的纬纱密度，单位为根每10厘米（根/10cm）；gw——纬纱纺出标准干燥重量，单位为克每百米（g/hm）；aw——纬纱缩率，%。1.2经、纬纱纺出标准干燥重量（g/m）按式（4）或（5）计算：式中：gj（w）——经（纬）纱纺出标准干燥重量，单位为克每米（g/m）；Nt——经（纬）纱线密度，单位为根每10厘米（根/10cm）；Nq——经（纬）纱英制支数。1.3股线重量按合并后的重量计算。1.4经纱总伸长率：上浆单纱按1.2%计算（其中，络筒、整经以0.5%计算，浆纱以0.7%计算）；过水股线（10×2）tex及以下按0.3%计算，（10×2）tex以上按0.7%计算。1.5间接纬纱的伸长率较小，可略去不计。1.6经纱总飞花率：粗号织物按1.2%计算，中号平纹织物按0.6%计算，细号织物按0.8%计算，斜纹织物按0.9%计算，线织物按0.6%计算。1.7经纱总伸长率、经纱总飞花率以及经纱织缩率是计算一平方米织物重量的依据，不是规定指标。2常用织物一平方米无浆干重快速计算方法2.1经验公式见式（6）。式中：λ——织物无浆干重系数；Ttj——经纬纱线密度，单位为特克斯（tex）；Ttw——纬纱线密度，单位为特克斯（tex）。2.2本经验公式中采用英式密度。2.3织物无浆干重系数λ取值范围如下：a)棉轻薄织物λ取0.0375；b)一般棉织物、涤棉轻薄织物λ取0.0385；c)棉厚重织物、一般涤棉织物λ取0.0395；d)涤棉厚重织物λ取0.0395；e)纯涤纶弹力织物λ取值可升高一档。本经验公式亦基本适用麻、粘胶等纤维。对股线、多种纤维混纺、提花等特种织物，应用本经验公式与实际误差较大。3各大类产品的各档重量的修正系数各大类产品的各档重量的修正系数见表1。表1重量修正系数重量档次kg/100m产品类别棉类（包括维棉、丙棉等）起毛绒类灯芯绒类本光漂白丝光漂白色布花布色织整理漂白色布花布漂白轧染卷染花布10.01-12.000.35120.59111.00001.69600.56770.35550.76041.66951.30432.07411.94933.469712.01-14.000.36250.60811.08291.73290.58470.36680.78021.70921.32702.10251.97203.509414.01-16.000.37390.62511.11131.76970.60170.37820.80011.74891.34972.13081.99473.549016.01-18.000.38520.64211.13961.80660.61870.38950.81991.78861.37242.15922.01743.588718.01-20.000.39660.65911.16801.84340.63570.40090.83981.82831.39502.18752.04003.628420.01-22.000.40790.67611.19631.88030.65270.41220.85961.86791.41771.21592.06273.668122.01-24.000.41920.69321.22471.91710.66980.42350.87951.90761.44042.24422.08543.707824.01-26.000.43060.71021.25301.95400.68680.43490.89931.94731.46312.27252.10813.747526.01-28.000.44190.72721.28141.99080.70380.44620.91921.98701.48582.30092.13083.787228.01-30.000.45330.74421.30972.02770.72080.45760.93902.02671.50842.32922.15343.826930.01-32.000.46460.76121.33812.06450.73780.46890.95882.06641.53112.35762.17613.866632.01-34.000.47590.77821.36642.10140.75480.48020.97872.10611.55382.38592.19883.906234.01-36.000.48730.79521.39482.13820.77180.49160.99852.14581.57652.41432.22153.945936.01-38.000.49860.81221.42312.17510.78880.50291.01842.18541.59922.44262.24423.985638.01-40.000.51000.82921.45152.21190.80580.51431.03822.22511.62182.47102.26684.025340.01-42.000.52130.84621.47982.24880.82280.52561.05812.26481.64452.49932.28954.065042.01-44.000.53260.86321.50822.28570.83980.53691.07792.30451.66722.52772.31224.104744.01-46.000.54400.88031.53652.32250.85690.54831.09772.34421.68992.55602.33494.144446.01-48.000.55530.89731.56492.35940.87390.55961.11762.38391.71252.58442.35754.184148.01-50.000.56670.91431.59322.39620.89090.57101.13742.42361.73522.61272.38024.223750.01以上0.62971.00811.74862.59580.98500.63401.24612.63981.85652.76272.49954.4315表2重量修正系数重量档次kg/100m产品类别涤棉类（棉与涤纶或其他合成纤维、人造纤维）中长类粘纤类【粘胶（人造纤维）与合成纤维】漂白色布花布色织整理轧染卷染色织整理漂白色布花布4.01-6.001.11181.55672.11920.60021.87421.34920.85570.20400.51851.25716.01-8.001.13131.58012.14650.61581.89371.35700.86350.21880.54831.30558.01-10.001.15081.60352.17380.63141.91321.36480.87130.23370.57801.353810.01-12.001.17031.62692.20110.64701.93261.37260.87910.24860.60781.402212.01-14.001.18981.65032.22840.66261.95211.38040.88690.26350.63761.450614.01-16.001.20931.67372.25570.67821.97161.38820.89470.27840.66731.498916.01-18.001.22881.69712.28300.69381.99111.39600.90250.29320.69711.547318.01-20.001.24831.72052.31020.70942.01061.40380.91030.30810.72691.595720.01-22.001.26771.74382.33750.72502.03011.41160.91810.32300.75661.644022.01-24.001.28721.76722.36480.74062.04961.41940.92590.33790.78641.692424.01-26.001.30671.79062.39210.75612.06911.42720.93370.35280.81621.740826.01-28.001.32621.81402.41940.77172.08861.43500.94150.36770.84591.789228.01-30.001.34571.83742.44670.78732.10801.44280.94930.38250.87571.837530.01-32.001.36521.86082.47400.80292.12751.45060.95710.39740.90551.885932.01-34.001.38471.88422.50120.81852.14701.45840.96490.41230.93521.934334.01-36.001.40421.90762.52850.83412.16651.46620.97270.42720.96501.982636.01-38.001.42371.93092.55580.84972.18601.47400.98050.44210.99482.031038.01-40.001.44321.95432.58310.86532.20551.48180.98830.45701.02452.079440.01-42.001.46261.97772.61040.88092.22501.48960.99610.47181.05432.127742.01-44.001.48212.00112.63770.89652.24451.49741.00390.48671.08412.176144.01-46.001.50162.02452.66500.91212.26401.50511.011
