Nylon in 1970s: Carpet bulked yarn
Read the condition on Nylon before the nickname. Year 1970s, line “Carpet bulked yarn,” figure 6. Thermal mark 30/100 versus the atlas. Conductivity note: low. A material is what it is made of, the condition it survives, and where it goes afterward. Nylon under “Carpet bulked yarn” in 1970s should say which, with 6 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.
Scores compare Nylon with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates. Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
Nylon (PA6 / PA66) is a family of grades whose density ~1.14 g/cm³, heat band PA6 ~220 °C; PA66 ~260 °C, and fire letter combustible, melt-drip. Nylon is sold as grades, not as a single substance. Chemistry PA6 / PA66, density ~1.14 g/cm³, heat band PA6 ~220 °C; PA66 ~260 °C. This atlas treats Nylon as a system: mill route, coatings, tests and the cavity it sits in.
Conductivity note: low. Insulation score 30/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: combustible, melt-drip. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide. Origin: DuPont 1935–38, United States. The process chapter follows feedstock → conversion → forming → finish → install.
The label keeps Nylon, 1970s, and 6. “Carpet bulked yarn” is the condition on the figure.1970s
