What Are the Steps Involved in Rayon Production?

Environmental requirements
During rating, the required background should be neutral gray (between level 1 and level 2 of the color-changing gray card). In order to avoid the influence of external light, our rating must be carried out in a dark room. At the same time, no other debris can be placed in the light source box.
2. Personnel requirements
The rater cannot be color blind or color weak, cannot wear colored glasses, and the rater should wear neutral gray work clothes. During rating, the incident light of the light source box is about 45° at an angle to the textile surface, and the rater's observation direction is roughly perpendicular to the textile surface.
