摘要： PROBLEM TO BE SOLVED: To provide a spinneret pack for composite synthetic fiber, wherein the spinneret pack for composite spinning can cancele height difference between spinnerets for composite spinning and ensure polymer seal axial force required between superposed layers of the spinneret by dividing only the spinneret holder holding the spinneret so as to correspond to each spinneret. SOLUTION: The conventional spinneret packs for composite spinning generally hold plural spinnerets in a pack but, when holding plural spinnerets with a spinneret holder, fastening force insufficiency of the spinneret is caused by height size difference of each spindle. As the result, yarn physical properties are decreased, stable production is disturbed and designing of the pack structure and spinnerets and for suppressing the trouble, is hard. Sufficient ensuring of the fastening force of a conjugate spinneret, acquiring of an easily designable low cost pack structure and ensuring of spun yarn quality are future great problems.
