<p style="line-height: 1.75em; text-align: justify;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">以JC/Modal(50/50)18.2 tex*18.2tex,622根/10cm* 315根/10cm,162.6cm条格布为例介绍其织部生产工艺。</span></p><p style="line-height: 1.75em; text-align: justify;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><br></span></p><p style="line-height: 1.75em; text-align: justify;"><strong><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">1.生产工艺流程</span></strong></p><p style="line-height: 1.75em; text-align: justify;">​<img src="https://dayaotex-edu.fsh.bcebos.com/v1/dayaotex-edu/%E6%89%AB%E6%8F%8F%E5%85%A8%E8%83%BD%E7%8E%8B%202023-06-15%2017.44_5.jpg?authorization=bce-auth-v1%2F59b7a26546d74b64bfd056b483465817%2F2023-06-15T10%3A46%3A38Z%2F-1%2F%2F418990c60b488061649c978a9baf4add311145adae53b9ff47853f0db0ddc8b2" style="width: 920px;" data-filename=""><br></p><p style="line-height: 1.75em; text-align: justify;"><strong><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">2.生产工艺要点</span></strong></p><p style="line-height: 1.75em; text-align: justify;"><strong><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><br></span></strong></p><p style="line-height: 1.75em; text-align: justify;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">(1)络筒:Modal纤维纱强力高、伸长小、条干均匀、杂质少、毛羽多而长,故宜采用“低速度、</span><span style="caret-color: red; font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">小张力、大隔距</span><span style="caret-color: red; font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">”的络筒工艺。在自动络筒机上,络筒速度必须控制在1000m/min以内,以减少摩擦和伸长,Modal纤维纱身光滑,宜采用空气捻接器接头或自紧结。络筒工艺参数:络纱张力9~10档,络筒线速度950m/min。</span></p><p style="line-height: 1.75em; text-align: justify;"><span style="caret-color: red; font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><br></span></p><p style="line-height: 1.75em; text-align: justify;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">(2)整经:采用“低速度、小张力”工艺,以保持纱线的弹性。在设备允许的条件下,尽量采用整批换筒,分段配置张力圈重量。生产本例产品时,整经采用贝宁格ZC-L型整经机,该设备采用张力棒导纱,通道光洁,有利于控制毛羽再生并适当减少毛羽。为保证全幅经纱张力均匀一致,升速要快,速度要恒定。为了减少后工序的并绞头,在落轴前穿一根分层绞线,每轴一根。主要工艺参数:整经速度600m/min,滚筒压力值7档,张力配置15档,卷绕密度0.53~0.58g/cm3,伸缩筘横动距离2cm。</span></p><p style="line-height: 1.75em; text-align: justify;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><br></span></p><p style="line-height: 1.75em; text-align: justify;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">(3)浆纱:由于Modal纱及其混纺纱与纯棉纱相比单纱强力与纯棉纱接近,而毛羽却比纯棉纱多,其弹性接近于涤棉纱,吸浆性能好,因此浆纱工序宜采取“以贴伏毛羽为主,渗透、被覆并重,严格控制回潮”的原则,注意调浆的浆液含固量。本例产品的浆料配方及调浆工艺见表7-10,上浆工艺及上浆效果见表7-11。</span></p><p style="line-height: 1.75em; text-align: justify;"><img src="https://dayaotex-edu.fsh.bcebos.com/v1/dayaotex-edu/%E6%89%AB%E6%8F%8F%E5%85%A8%E8%83%BD%E7%8E%8B%202023-06-15%2017.44_6.jpg?authorization=bce-auth-v1%2F59b7a26546d74b64bfd056b483465817%2F2023-06-15T10%3A47%3A28Z%2F-1%2F%2F1c1f4508210eb518a0c91a54e469ece07ecc22cfb9b8d063a64a91b1e3f5b170" style="width: 920px;" data-filename=""><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><br></span></p><p style="line-height: 1.75em; text-align: justify;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">(4)织造:不同型号的织机,对织造工艺的要求有差异,但是总的来说,Modal纤维吸湿性</span><span style="caret-color: red; font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">强,干湿强力存在差异,因此要控制好车间温湿度。另外</span><span style="caret-color: red; font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">Modal纤维纱因毛羽较多,在织造时,容易在经停架处形成毛羽聚集,形成“绞花”现象,因此要注意清洁。织造采取“早开口、中小张力”的工艺原则。本例产品采用丰田JAT610型喷气织机织造,主要织造工艺参数见</span><span style="caret-color: red; font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">表</span><span style="caret-color: red; font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">7-12。</span></p><p style="line-height: 1.75em; text-align: justify;"><img src="https://dayaotex-edu.fsh.bcebos.com/v1/dayaotex-edu/%E6%89%AB%E6%8F%8F%E5%85%A8%E8%83%BD%E7%8E%8B%202023-06-15%2017.44_7.jpg?authorization=bce-auth-v1%2F59b7a26546d74b64bfd056b483465817%2F2023-06-15T10%3A52%3A37Z%2F-1%2F%2Ff3fb37ab4032925ad3c03d6365bf24d2cd2c20b0991635838a6d7fe7937e39df" style="width: 920px;" data-filename=""><span style="caret-color: red; font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><br></span></p>
