Description

地毯纺丝网络器气流打结加捻喷嘴及气流打结加捻方法 Technical Field
本发明涉及一种既能够适用于3500-6000分特的纺丝的网络打结，又能够让3500-6000分特的纺丝在通过网络器气流打结加捻喷嘴丝线通道内被气流加捻手加捻的地毯纺丝网络器气流打结加捻喷嘴及气流加捻方法，属网络喷嘴制造领域。
Background Art
在现在的地毯纺丝网络技术领域中，由于网络嘴在结构设计上只在丝线通道顶部中间开主气孔，见附图4。因此，现有的网络喷嘴只适用于3500分特以下纺丝的网络打结，超3500分特的丝线打网络，需要后道的网络机进行二次网络工序，方可满足客户的需求，这种工艺路线，不仅能耗高、损耗大，产量低、速度慢，而且产品后道网络后，各项指标难于达到一致，产品质量不稳定。
 Technical Solution
设计目的：避免背景技术中的不足之处，设计一种既能够用于3500-6000分特的纺丝的网络打结，又能够让3500-6000分特的纺丝在通过网络器气流打结加捻喷嘴丝线通道内被气流加捻手加捻的地毯纺丝网络器气流打结加捻喷嘴及气流加捻方法。
设计方案：为了实现上述设计目的。本发明在现有地毯网络器喷嘴结构的基出上，在网络器喷嘴的丝线通道两侧壁相对一前一后开有气流加捻喷气气流孔的设计，是本发明的主要技术特征。这样设计的目的在于：在保留陶瓷体底部打网络的丝线通道上方的单孔外，再在丝线通道两侧壁分别增加气流加捻喷气气流孔，即采用'一主两副'的气流孔设计，气流加捻喷气气流孔的气流来源于受控的调压阀后。主气孔（打结气孔）的孔径3-4mm（或3.5mm）丝线通道两侧的气流加捻喷气气流孔的孔径为0.5-1.5mm（或1.2mm），其主气孔与丝线形成90度吹捻，气流加捻喷气气流孔与丝线形成斜度的吹向，迫使多股丝线在通过网络器丝线通道内被气流加捻气流手按顺时针或逆时针向加捻成丝线绳，即让多股丝线加捻成型。即，'一主两副'气流孔的设计，主气孔气流来自于压缩空气，仍起网络打结的作用，副气孔的气流来源于受控的调压阀后，作用是根据客户质量要求，让丝线形成顺时针方向的高速旋转，增加旋涡的力度，让主气孔在网络打结时更紧，达到粗旦纺丝因加粗而不牺牲丝线品质的目的。
技术方案1：一种地毯纺丝网络器气流打结加捻喷嘴，网络器喷嘴中丝线通道中部底部开有网络结打结气孔，所述丝线通道两侧壁相对一前一后分布的气流加捻喷气气流孔位于网络结打结气孔后部。
技术方案2：一种地毯纺丝网络器气流打结加捻喷嘴的气流打结加捻方法，当多股需要被打结和加捻丝线通过网络器气流打结加捻喷嘴中的丝线通道时，位于网络器气流打结加捻喷嘴丝线通道底部打结气孔完成对多股丝线喷气网络打结后，网络打结后的丝线在通过网络喷嘴丝线通道时，被网络喷嘴丝线通道两侧侧壁上的加捻喷气气流孔喷出的气流按顺时针旋转或逆时针方向旋转加捻，进而完成多股丝线的加捻。
 Advantageous Effects
本发明与背景技术相比，一是本发明不仅具有网络打结的功能，而且具有多股丝线加捻的功能，多股丝线在通过网络喷嘴的丝线通道内时，被丝线通道内的加捻气流手加按顺时针或逆时针方向加捻成所需绳；二是本发明适用于3500-6000分特的纺丝直接打网络结、加捻，可降低纺丝指标的差异率80%以上，提高丝线的质量稳定性与可纺性，同时达到提高生产效率与节能降耗的目标。
