Quantitative analysis method for import and export textile polyester fiber
1 Scope
This standard specifies the use of a microprojector method in a molten state to contain polyparaphenylene in a blend of non-polyester fibers that have been removed.
Two or three of ethylene glycol diester (PET), polytrimethylene terephthalate (PTT) and polybutylene terephthalate (PBT)
A quantitative analysis method.
This standard applies to the quantitative analysis of textiles and their products containing polyester fibers.
2 Normative references
The terms in the following documents become the terms of this standard by reference to this standard. For dated references, only dated

3 Principle
According to polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT) and polybutylene terephthalate
(PBT) difference in melting point, after melting one or two fibers, the change in the number of fibers and the cross section are measured by microprojector analysis.
Product, thus calculating the corresponding percentage content.
