梳棉锡林针布齿深对纺纱质量的影响

Influence of Carding Cylinder Card Clothing Tooth Depth on Yarn Quality

研究不同齿深锡林针布对纺纱质量的影响。分别采用两种齿深的锡林针布,在梳棉机两种出条速度条件下进行梳理对比试验,并采用相同的后序工艺将其纺制成纱,对纱线条干、强力和毛羽指标进行检测。结果显示:对于纱线条干和强力指标而言,总体上0.3mm齿深要好于0.4mm齿深,在相对高产时具有较好优势;但对于毛羽指标影响趋势有所不同,在出条速度120m/min时,浅齿有优势,而在出条速度145m/min时深齿显出优势。认为:锡林针布齿深对纱线的质量有影响,同时纺纱质量也会受到产量的交互影响。

The influence of different card clothing tooth depth on yarn quality was studied.Two kinds of cylinder carding cloths with different tooth depths were adopted separately.The carding comparison experiments were carried out under the condition of two sliver output speeds in carding machine.The same post processes were used for yarn spinning.The yarn evenness,strength and hairiness were tested.The test results showed that 0.3 mm tooth depth was better than 0.4 mm tooth depth from the yarn evenness and strength perspective.It had better advantage in relative higher yield.However,the effect trend for hairiness was different.When the sliver output speed was 120 m/min,smaller tooth depth had advantage.While the sliver output speed was 145 m/min,larger tooth depth showed the advantage.It is considered that the tooth depth of cylinder card clothing has effect on the yarn quality.Meanwhile,the yarn quality is also interactively influenced by yarn yield.
