There are many types of spinnerets, and the nonwoven ones used to make masks are just one. Below, The Main types of spinnerets on the market have been sorted out for you by Sheng Sha Precision Machinery.

(1) Spinneret for wet spinning

Spinning spinnaster board is mainly used in high-end women's clothing such as bedding, dress and blouse, and cigarette filter tip manufacturing. Through the tool independently developed by our company, the equilateral triangle hole and round hole with side length of 0.030 ~ 0.0150mm can be punched.

(2) Dry spinning spinneret

Dry spinning is a spinning method in which the resin is dissolved by solvent, extruding through holes in spinneret, and the solvent is vaporized by hot air.

(3) Spinneret for melt spinning

Spinneret used in melt spinning is a representative spinneret used in the manufacture of synthetic fibers such as polyester and polyamide.

In addition, through self-made tools and unique processing technology, the processing precision of the surface can be selected from mirror treatment, grinding (pear surface) treatment, super mirror treatment.

A spinning process in which a thermoplastic resin is heated and melted, at a certain speed, in air or water, by extrusion through a spinneret, and then cooled and solidified into a fiber.

(4) Dry-wet spinning spinneret

Dry and wet spinning is suitable for the manufacture of acrylic fiber and aramid fiber. High strength and high elasticity fibers can be produced by using the spinning technique of densification.

Dry and wet spinning refers to the spinning method in which the resin extruded from spinneret goes into the solidification liquid immediately after it travels in the atmosphere and solidifies into fiber.

(5) Spinneret for composite spinning

By compounding the raw materials, the production of high-functional fibers, such as microfiber and conductive fiber, which cannot be produced by a single type of resin is realized.

The spinneret assembly for composite spinning has high technical requirements on the position matching, temperature control and flow path design of the upper part.

Composite spinning is a process in which more than two different resins are spun simultaneously from a single pore and the properties of each resin are used.

(6) Water needle plate

Spunlaced method is a reinforcement method that USES high speed water to impact the fibers and make the fibers intertwine with each other to achieve a certain strength of the cloth surface. Non-woven fabric made by this method is also called "water winding non-woven fabric", which is widely used in wipes, cosmetic products, surgical gowns and other materials.

The long jet of cylindrical water can improve the winding with high performance, reduce the processing loss, disperse the water, and achieve the effect of energy saving.

(7) Spinnerets and die heads for non-woven fabrics

Spinneret for viscose spinning

Spinning sticky non-woven cloth is a kind of non-woven cloth formed by melting the resin at low melting temperature and drawing the spinneret into a net. Both light, soft, strong characteristics, the variety of production.

Melt spraying cloth spinneret

Melt-jet non-woven cloth is a kind of non-woven cloth which USES high speed hot air flow to draw the fiber extruded from spinneret and make the fiber wound. Non-woven fabrics used in masks and industrial filter elements can be manufactured from raw resin to the first stage.

(8) Spinneret for hollow fiber

Hollow fiber forming mould, hollow fiber for artificial dialysis, spinneret of hollow fiber for filtration, can be designed into single type and various type, and three-weight tube type can also be designed.
