Practical Technical Tips For Polytetrafluoroethylene (PTFE) Sewing Thread
- Jul 30, 2018 -

1, this product is the 100%PTFE (PTFE) material manufacture, mainly uses the material the temperature resistance performance ( -196~260℃) and the corrosion resistance, the hydrolysis, the oxidation resistance performance. 

2, the use of this product in the process, please be sure not to use open flame combustion, to avoid the formation of harmful gases to the human body.

3, according to the National Standard measurement unit requirements and international habits, the company's products using "Dtex" (sub-special) as line density measurement units for a certain unit length of the quality (G/L), such as 1350dtex, is 10000 m sewing thread quality is 1350g (0.135g/m)

The other line density unit "Den" (Daniel, abbreviation "Dan", abbreviated "D"), which is used in the industry, refers to the quality of the length of 9000 meters, so the relationship between the two is: 1den = 0.9dtex.

4, PPS or Ptfe/pps composite filter material after sewing the filter bag, there may be holes in the fiber's recovery is not good, pinhole significantly, the effect of filter bag filtration efficiency of the situation, it is recommended to use a smaller type of sewing needles or contact us to select such filter materials dedicated sewing thread (such as Ptfe/pps Composite line).
