The Spinnability of Aqueous Polymer Solutions

Spinnability has been measured for extract from root of Abelmoschus Manihot and for aqueous solutions of sodium alginate, poly(ethylene oxide) (PEO), and sodium carboxymethylcellulose (NaCMC). The maximum thread length, in other words, drawing length increased linearly with a raising velocity, that is to say, drawing velocity of a rod for extract from root of Abelmoschus Manihot and for aqueous solutions of sodium alginate and PEO. The constancy of the drawing length against drawing velocity was obtained for aqueous solutions of sodium alginate and NaCMC. Such difference in spinnability was discussed in connection with junction formation among polymers in aqueous medium.
