Definition For The Week - Extruder
|
 Meltblown, spunbond, and spun staple fiber all begin with an extruder turning thermoplastic pellets into melted polymer. This week's definition describes the basics of what an extruder is and how it works. This week's definitionBelow are a few of the links I used while researching the definition. Davis Standard ExtrudersRoutsis Plastic TrainingGreat animation of an extruder. Click on picture to start animation. There are several on this site. Good explanation of an extruder from Reifenhauser Free book on extrusion from Google In the extrusion of plastics, raw thermoplastic material in the form of
small beads (often called resin in the industry) is gravity fed from a
top mounted hopper into the barrel of the
extruder. Additives such as colorants and UV inhibitors (in either
liquid or pellet form) are often used and can be mixed into the resin
prior to arriving at the hopper. The material enters through the feed throat (an opening near the rear of
the barrel) and comes into contact with the screw. The rotating screw
(normally turning at up to 120 rpm) forces the plastic beads forward
into the barrel which is heated to the desired melt temperature of the
molten plastic (which can range from to depending on the polymer). In
most processes, a heating profile is set for the barrel in which three
or more independent PID controlled
heater zones gradually increase the temperature of the barrel from the
rear (where the plastic enters) to the front. This allows the plastic
beads to melt gradually as they are pushed through the barrel and lowers
the risk of overheating which may cause degradation in the polymer. Read the rest of this articleArticle Source: AbsoluteAstronomy.com |
Training That Works - Uses for Nonwovens
|
 Last week and this week I have linked to articles that give a very good overview for the multitude of uses for nonwovens. This article was featured in the Indian Textile Journal in September of 2009. The article was written by Supriya Pal. It is very thorough. I would suggest having every employee read this and last weeks articles.

Needle
Designs and Their Effect on the Needled Nonwoven |
 Foster Needle Company has some articles on their web site. This one is particularly good. For anyone in the needlepunch industry, this should be required reading for your operators. Many operators do not know how a needle works to bond fibers.Without
a doubt felting needles are one of the most important elements relating
to a needlepunching operation. The felting needles can literally make
or break a needled product. As a needle supplier it is our job to make
the proper needle recommendations based on a number of considerations in
order to give each customer the best needle for his or her own special
characteristics. Making the proper needle recommendation can be very
involved. A needle that works well for Customer "A" may not work well
for Customer "B" even though they are producing the exact same product.
Foster Needle produces thousands of types, sizes and variations of
felting needles and I hope to show you today how and why we make the
needle recommendations we do.
There are numerous
characteristics pertaining to needle design that must be considered to
produce a more effective needle for a given customer or application.
However the four main areas that should be considered: Read the rest of the article. |
