Tantalum Spinneret Is The Key Of Chemical Fiber Textile Machine Parts.
Sep 30, 2017

Chemical fiber spinning machine precision parts, also called spinning top. The shape of the spinneret is commonly hat shape, round shape or corrugated shape, there are many of the same size on the surface of hole. When spinning, spinning solution or melt through from these microporous, state to trickle into a coagulation bath or in the air, the solidification and cooling as fiber. 

Spinneret, distribution boards and filtering materials together form a spinneret components. Distribution board adhesive solution or melt evenly dispersed into many tiny holes. Filter material used to filter dross. Component, spinneret in the most important, and directly affects the quality of the finished silk. According to the different method of spinning spinneret is divided into melt spinning, wet spinning and dry spinning three. 

Melt spinning spinneret is generally round shape, so it is also called spinneret, also have a rectangle. Circular spinneret stainless steel with high temperature resistance, simple structure, easy fabrication. For melt spinning spinneret on the aperture, associated with varieties of fiber and spinning conditions, generally from 0.2 to 0.2 mm in diameter. Spinning hole number is generally a few holes, palm a hole, spinning staple hole number up to 400 ~ 2000 in general. Wet spinneret shape, also called jet mainly for the hat, there are also disc and strip shape (corrugated), with the strong corrosion resistance of gold platinum alloy or titanium, niobium, tantalum, stainless steel and other metals. 

Spinning yarn when using small number of jet hole cap, but when spinning staple fibre is introduced large porous spinneret, hole number can reach 2 ~ 150000; Hole as very much, the number of combinations can be used into several spinneret, deserve to be on the same piece of stainless steel plate. Wet spinning spinneret diameter ratio of melt spinning spinneret small aperture, aperture is generally 0.05 ~ 0.1 mm. 

Commonly used dry spinning spinneret (board) has two kinds of cap shape and circular, aperture is 0.07 ~ 0.16 mm, hole number is 300 ~ 1200, made from stainless steel or special alloy steel.
