My original copy of this book was lost in the mails, so this review is unavoidably late.There is one advantage of the delay, however. I have been able to check my opinion with that of a colleague, who is a spitining expert. He was initially disappointed because he found so few new leads to problems that had been facing him. On reflection, however, he realized that, to quote, "But,, t,o be fair, I thiiik that we must admit that very little is known about the subjects t,hat aren't treated adequately in the book, in spite of the incredible size of the fiber industry and the large expenditiire on research and development." This book, then, is not so much for the specialist as it is for those who hope to become specialists, or those like myself, who never expect to spin fibers, but need to know a good deal about the field.The two chapters by A. Ziabicki, on fundamentals of spinning, were very interesting to me. I particularly liked the discussion of tensile viscosity and of the factors limiting the amount of draw-down during spinning. I wondered whether more emphasis shouldn't be paid to the amount of stored elastic energy in the spinning melt or dope, rather than the main relaxation time, particularly when dealing with fiber breakage and fluctuations of diameter.
