Test method for dynamic draftability of spandex filament

1 Scope

This standard specifies the test methods for the dynamic draftability of spandex filaments. This standard is applicable to spandex filament with linear density of 10.0dtex~111.1dtex, and other specifications can be used for reference.

2 Normative references

The following documents are essential for the application of this document. For dated references, only the dated version applies to this article pieces. For undated references, the latest edition (including all amendments) applies to this document.

3 Terms and Definitions

The terms and definitions defined in GB/T 4146 (all parts) and the following terms and definitions apply to this document. 3.1 Elongation at break in dynamic unwind state.

4 Principles

The sample is actively unwound at a certain speed. Under the condition that the input roller speed (ie. unwinding speed) remains unchanged, by continuously increasing the input roller speed The speed of the roller is increased, and the draft ratio during unwinding is increased until the sample breaks. The dynamic stretchability of the samples was characterized by the dynamic elongation at break. The schematic diagram of the principle is shown in Figure 1; the schematic diagram of the result is shown in Figure 2. Figure 1 Schematic diagram of the principle ......
