喷丝头是化纤設备紡絲机中重要元件之一。計量泵以S～10个工业大气压将碱性粘胶溶液連續不断地通过过滤器,压到沉浸在酸性凝固液中的噴丝头,再由噴絲头底面成千上万的微孔中挤出而与凝固液接触,即凝固成可紡的纤維束,微孔的主要功用是将粘胶挤成直徑約0.06～0.10毫米的质地細密纤維束。微孔直徑一般为0.06～0.10毫米,公差为d_(-0.002)~(+0.004),椭圓度≤0.003毫米,孔道光洁度为▽▽▽▽_(10)。
Spinneret spinning machine is one of the important components of chemical fiber equipment. Metering pump to S ~ 10 at atmospheric pressure will be a continuous solution of alkaline adhesive through the filter, pressure immersed in the acidic coagulation liquid spinneret, and then from the bottom of the spinneret thousands of micro-hole squeeze And come into contact with the coagulating liquid, that is, coagulate into a spinnable fiber bundle. The main function of the micropores is to squeeze the viscose into fine textured fiber bundles having a diameter of about 0.06 to 0.10 mm. Pore diameter is generally 0.06 ~ 0.10 mm, tolerance d _ (- 0.002) ~ (+0.004), ovality ≤ 0.003 mm, hole finish ▽ ▽ ▽ ▽ _ (10).
