織軸形成裂軸的原因分析

       由于經絲相互之間的收縮不勻,經軸中的經絲會形成排列混亂,織軸特別是外層經絲會嵌入內層,嚴重時使經軸上的絲層裂開,兩個邊側會變得凸出,這就是常說的裂軸。它多發生在兩個邊側,中問部位較少,一般在上機幾天后才開始發生。
       一旦發生裂軸,就會形成嚴重的經柳、寬急經等問題,因此是嚴重的半制品質量事故之一,影響工廠的生產效率和產品質量,嚴重時只能采取剪軸,有條件的廠家進行倒軸后可重新上機,也有不少廠家直接將其報廢。
       產生裂軸的主要原因在于經絲相互之間的收縮不勻。從織軸徑向來看,內層經絲由于緊貼芯管,收縮受到制約;但越到外層,這種束縛就越小。
       另一方面,經絲上漿后雖然一般均安排放縮時問,但回縮不充分。而且在濕度相對較大的織造車間,漿膜吸濕后對絲條的固著作用減弱,應力得到釋放。外層經絲先于內層經絲吸濕,且經軸中間的吸濕大于兩邊,造成中間經絲的回縮高于兩邊,故兩個邊側會變得凸出。隨著這種收縮誤差的積累,造成兩邊部位裂軸。如果織軸中間某個部位有應力集中處(如成形或張力變異),則也可隨著收縮誤差的積累而發生中間裂軸。
