cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  麻纱为细特低密织物。是一种表面纵向呈现宽狭不等细直条纹的轻薄棉织物。因手感挺爽如麻而得名。麻纱具有“直、薄、爽、透”的风格,即纹路应该直且清晰,而织物要轻薄、挺爽透气。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (二)织物种类</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (1)普通麻纱:普通麻纱一般用3/1变化纬重平组织或1/3变化纬重平组织织物。在织物的表面出现宽窄不同的纹路。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (2)异经麻纱:异经麻纱直条纹清晰突出,孔眼较大,透气性好。它是将上述组织配合以不同特数经纱的麻纱织物。如单根排列的经纱号数小,双根排列的经纱号数大。或者按规定的顺序和纬纱交织。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (3)柳条麻纱:柳条麻纱是具有空筘齿效应的稀疏平纹织物。织物透气性优良。不同之处为:经纱用细特股线。股线的捻向与单纱捻向相同。经纱每隔一定距离留有一定的间隙,这样就会出现这些空隙形成的纵向条子。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  柳条麻纱细洁轻薄,手感挺爽,孔隙清晰、透气。外观类似高级丝绸织物。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (4)变化麻纱织物:变化麻纱织物的变化组织可以获得方格、条子、人字等各种外观。提花麻纱织物(用平纹地小提花组织)的布面可以呈现各种小花纹的外观。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (三)麻纱织物设计</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  麻纱为仿麻织物,做夏季衣料用。应使织物具有麻织物的特点。设计时,应使织物条纹清晰、采软挺爽、牷薄透,不同组织的麻织物各有不同的加工工艺和风格特址。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  1.普通麻纱织物</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (1)原纱要求(棉或涤/棉织物):为使织物的直条纹整齐,纱线的条干必须均匀一致,当纱特小于14.5tex时,宜用精梳纱。这就要求选用成熟度好、短绒少的原棉。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (2)纱线特数的选用:麻纱为薄型织物,为使织物轻薄、凉快,纱特应≤21tex,一般为13-18tex(32-45英支)的细特纱。若希望条纹明显凸出,可使经纱略粗于纬纱或经纬纱特数相同或相近。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (3)纱线的捻度:捻度是形成麻纱风格的一个很重要的因素。麻纱条纹要求挺直,手感要求既柔软又挺爽。因此,经纱要求捻系数较高,而纬纱捻系数比一般织物小。在不影响纬向强力的前提下,纬纱捻系数越低越好。而经向捻系数可用公式aj=a一般+10%计算。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  一般情况下,普通麻纱采用((18×18)tex[(32×32)英支]的纱线,aj=370-400(3.9-4.2英制);aw=285~315(3.0(3.0-3.3英制)。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (4)织物紧度的配置:麻纱织物要求具有较好的透气性能。所以织物紧度不宜太高,应比平布略小。一般情况下,E总=74%-77%,Ej=40%~50%,Ew=45%~55%%。纬密须比经密高10%~15%。用此工艺织出的织物,布面直条纹比较明显,几能弥补因纬纱捻度低而降低纬强的缺点。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (5)织物的组织:织物一般采2/1或3/1变化纬重平组织。3/1变化纬重平组织的经纬交织次数较少,纬纱的浮长长,而织物密度又较小,经纱容易位移,会形成稀密不匀的现象而影响组物的外理 故日前很少用。(6)纱线的捻向配置:纱线一般采用经纬纱同捻同。这样可以便经纬纱咬合紧密,织廷,而且,还可以防止织物下机时,因张力减小而引起的纱线解捻卷边。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (7)其他:常见麻纱的织制工艺与“细平布”相仿,但在穿经时,将一个完全组织中的经纱身人同一箱齿内,两根经纱应分别以单根穿人经停片和综丝,以保持平直,不致扭绞。染整加工中应加强丝光时的阔幅,经耐久性挺爽整理。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  2.异经麻纱</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  普通麻纱的经纬纱特数相同或相近,使纬纱弯曲程度不够大。因此,织物的纵向条纹不错凸出,经印染加工受辊筒多次轧压后,凸纹常被轧平,致使麻纱的特点不够明显。为此,应设法史麻纱具有更明显凸出的条纹。异经麻纱是采用不同特数的经纱按规定的顺序相间排列,并与适当特数的纬纱相配合。经实验得出,单根排列的经纱特数应小于双根排列的经纱特数,两科经纱特数差异在20%左右时,布面条纹最为凸出。纬纱特数比单根排列的经纱特数小时,织物的效应更好。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  经钟且方能大的缩索而双想排列的经纱具有较小的缩率,这检排列,织物的凹凸效果显著。织造时,采用双轴或一轴织制。坯布经漂白或染色后整理后,可做夏季男衬衫的面料。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px;

line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  3.柳条麻纱织物</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  柳条麻纱织物的质地更细洁轻薄且穿着时更为凉爽舒适,并给人以高级丝绸感。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (1)纱线特数的选择:织物采用特细特股线(同巴里纱)和精梳纱,经纬纱采用6tex×2~10tex×2(60英支×2~100英支×2)。经烧毛工艺,得到的织物洁净,布孔清晰,透气性好。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px;

line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (2)纱线捻度、捻向:织物采用高捻纱,经纬同捻向,且股线与单纱捻向同向。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  (3)织物紧度:Ej&gt;Ew,平纹。经纱采用空筘穿法,织物细薄、坚牢、透气性优良,经向条纹且经向强力小。Ej=50%-60%E.=35%~45%(4)其他:柳条之间的孔隙和柳条的宽度配置恰当。d柳=2.0~2.5mm(宽度),d空隙=0.5~0.6mm,孔隙为条纹宽度的25%。钢筘:刚性好的厚齿片(防止条纹边缘边纱向柳条孔隙处移动)。</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px;

line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">  4.变化麻纱织物</p><p style="text-align: left; max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="text-align: left;
