1961 Volume 1

The difficulties involved in interrelating paper properties are examined. Qualitative relationships through trends and experience are noted and the special case of quantitative interrelationship among burst, tensile and stretch is described .

More basic considerations such as fibre length, fibre strength, sheet density, fibre orientation and interfibre bonding are individually related to common strength properties and special consideration is given to tearing strength . These more basic considerations are themselves interrelated and an attempt is made at a unification of paper properties through such basic interrelationships . It is suggested that fibre strength, in a broad sense, is of particular importance in such unification .
