Microscopic Surface Image of SunRising Nozzle Before Use

Microscopic Surface Image of SunRising Nozzle After 12 Days of Use

Uniformity Variation During Use

Trend charts show both nozzles generally fall within 0.80–1.20.

Over a 10-day nozzle usage cycle, in-house imported nozzles exhibit a higher out-of-spec ratio and greater variability in uniformity.

Thus, in terms of uniformity comparison, [SunRising Nozzle] outperforms in-house imported nozzles.

[SunRising Nozzle] Stable Uniformity

Oil Content Variation During Use

Although oil content showed minimal differences in tests at the same spindle, compared to other spindles of the same specification,

[SunRising Nozzle] demonstrates better oil content stability.

[SunRising Nozzle] Superior Oil Content Stability

Elongation Variation During Use

Under SunRising Nozzle testing, elongation mostly falls within standard values.

In-house imported nozzles show a higher out-of-spec ratio during use.

[SunRising Nozzle] Elongation Within Standard Values, Superior to In-House Imported Nozzles

Phase 2 Test Summary

SunRising Nozzle reached a cumulative usage of 23 days across the previous "90/24 Black Yarn" test and the current "125/32 Composite Yarn" test.

The nozzle surface shows no significant wear marks, indicating a high level of wear resistance.

Uniformity, oil content, and elongation comparisons clearly favor SunRising Nozzle over in-house imported nozzles, with stable tension and significantly reduced yarn breakage on average during testing.
