Frequently Asked Questions     

What size yarn can you make?  

This depends upon whether you are talking about an open-end yarn or a woolen system yarn.  It also depends upon the fiber and or blend of fibers you want made.  Generally, the higher the % of synthetic yarn, the finer (or smaller) we can make the yarn.  The first thing we need to know is what system are you using to determine the size of the yarn.  Currently, there are ten different common measuring systems for determining yarn size.  Some of these various measuring systems are:  (1)  grains per 50 yds.;  (2) cotton count;  (3) worsted count;  (4)  wool run;  (5)  ply/grains;  (6) yards/pound;  (7) grains per 120 yards.;  (8) metric count (Nm);  (9) denier grams/9000M;  (10) tex/1000M;  (11) decitex/10000 (dtex);  and,  (12)  meters/kilogram.   To assist you, Crescent has created a special link.  In a single ply yarn we can produce yarn from 35 grains per 50 yards to 350 grains per 50 yards.  If we  two ply the 350 grain yarn, it will be a total of 700 grains per 50 yards.  To learn more on natural fiber yarn sizing see the yarn sizing chart.  To learn more about yarn conversion see the yarn conversion chart.












What types or grades of wool do you use?  

We use all types of wool.  Our standard wool is 56’s grade (the lower the grade the coarser the wool).  Our high end wool runs from 64’s grade up to 70’s grade.  Fine merino wools run 64’s to 70’s grade.  Other natural fibers we process are:

Angora (both rabbit and goat)





Merino Sheep


We also process a wide range of synthetic fibers of varying deniers (thickness).  Many of these synthetic fibers are fire retardant.  Synthetic fibers include, but are not necessarily restricted to, the following:













We also process a wide variety of vegetable based fibers including:






Where does your wool come from?  

Some of our wool is domestic (from the U.S.).  A lot of our wool comes from Australia and New Zealand.  Some of our wool also comes from South Africa.  It is interesting that wools from various countries have unique characteristics.  For instance, wool from the U.S. has a unique crimp in the fiber and makes very lofty sweaters, socks, hats, scarves and gloves.  Wool from South Africa felts very easily and is excellent at making berets.  We have perfected an excellent beret yarn made from all U.S. wool as this is required by our Department of Defense when doing government contracts.


Do you certify your yarns to be Department of Defense and/or NAFTA compliant?  

Absolutely!  We have been recognized by the Department of Defense for the excellent paper trail we provide our customers when they do government contracts.  We also have successfully gone through numerous audits by the Canadian government to insure NAFTA compliance.  Upon request, and at the time of shipping, you will receive all the appropriate compliance paperwork on any order you place with us.


We have our own fiber and we would like you to process our fiber on your spinning system, will you do that?  

We need to have a representative sample of the fiber before we can answer that.  The fiber must be properly processed before we can process the fiber.  A natural animal fiber must be scoured, or washed prior to processing.  Crescent does not have a scouring operation.  If you want to have us process this fiber on the woolen system the fiber length must be between 2 ½ inches to 3 ½ inches with 80% of the fiber being under 3 inches.  On the open-end system the fiber length must be between 1 ½ inches and 2 inches.  We do not encourage people to send us their fiber.  If the fiber is natural (wool, angora, camel, raccoon, alpaca, hemp etc.), there is often vegetable matter such as burrs and other contaminants in the fiber and this can cause extensive damage to our equipment.  Not only does this cause down time but the repairs can run into 10’s of thousands of dollars.  Our fiber suppliers know the strict specifications we demand of any fiber supplied to us.  Also, remember the minimum quantity must be over 500 pounds.
