text-align: justify;" align="justify"><span style="font-family: 微软雅黑, "Microsoft YaHei";">(1)仿麻织物一般采用涤纶,吸湿性差,结晶度高,吸色吸浆能力较差,在加工过程中,经丝摩擦易出现静电、毛丝以及沾灰等缺点。因此,在各道工序中,应严格控制质量,纱线张力不宜太大,要适中均匀;各工序要保持导丝器表面光滑,防止产生静电,要定期检查导丝零部件,及时更换。</span></p><p style="line-height: 1.75em;

text-align: justify;" align="justify"><br></p><p style="line-height: 1.75em; text-align: justify;" align="justify"><span style="font-family: 微软雅黑, "Microsoft YaHei";">①经纱扭结问题:由于仿麻织物经纱捻度较大,虽然经过定捻,但在浆纱湿区,经纱一出浆槽,还是容易出现互相扭结的情况。主要解决方式是:加大湿区张力,使纱线出浆槽后,每根经纱保持互相独立,多加几根湿分绞棒,用湿分绞棒有效地控制每一根经纱,使经纱之间不能相互扭结。上述方法根据情况可单独或联合采用。</span></p><p style="line-height: 1.75em; text-align: justify;" align="justify"><br></p><p style="line-height: 1.75em; text-align: justify;" align="justify"><span style="font-family: 微软雅黑, "Microsoft YaHei";">②烘房温度控制:一般浆丝采用轴对轴方式,每轴总经根数较少,而浆纱烘房内温度较高,纱线很容易烘干,几乎无回潮。这样在干分绞时,易产生脆断头,织轴倒头太多,所以要严格控制烘房温度,一般以80~90℃为宜,可保证浆纱回潮在6%左右,减少断头。</span></p><p style="line-height: 1.75em; text-align: justify;" align="justify"><br></p><p style="line-height: 1.75em; text-align: justify;" align="justify"><span style="font-family: 微软雅黑, "Microsoft YaHei";">(3)织造工艺要点:由于仿麻类织物的经、纬密度较小,布孔清晰,接头在布面上会很明显,从而影响布面风格和质量,因此,在准备工序尽量采用无结纱,织造断经后,接头要采用捻接的方式。在织造时严格控制稀纬和密纬疵点,把各部位张力调到最佳,同时定期检修送经、卷取部位,以保证稀纬和密路条数降到最少。由于此类产品经纬纱常采用不同纱线配置,操作时要特别主要分清纱线类型,防止用错。</span></p><p style="line-height: 1.75em;
