Four Inspiration From The Production Process Of Spunbonded And Melt Blown Nonwovens

One of the characteristics is to seize the leading products and form their own products.

It is impossible for any enterprise to get involved in all the technology of nonwovens. Only one or two of them can be used to give full play to their advantages.

China textile technology is the way to build up its own advantages in spunbonded and melt blown equipment, and occupy the market and serve the market by this advantage.

And relying on its own technology and equipment sets the advantages of the top, and has a high reputation at home and abroad.

China textile technology has been widely used in many provinces and cities in China. In addition, Turkey, India, Korea, Egypt, Saudi Arabia, Indonesia, Russia and South America have successfully produced projects in Argentina, and have been praised by users.

The two characteristic is to research and produce products that meet the needs of the market.

Nonwoven fabric is a new industry with wide market demand. Its technology and equipment must meet the market demand.

At present, the spunbonded and melted spray process technology and equipment have been formed in a series of machines ranging from 1.6 m to 3.2 m, and the weight of the finished products ranges from 10 g / m2 to 200 g / m2 to 400 g / m2, and the spinning speed depends on raw materials, processes and products.

Products for medical, health, packaging, protection and building insulation, pportation and other different uses are available.

Spunbond

The raw materials are polyester chips, which can be made of "sandwich" or a variety of superposition forms. There are single layer spunbonded or melt blown processes, spunbonded and melt blown processes are added, spunbonded with dual mold melt blown and spunbonded technology, and 2 spunbonded with 3 melt blown, plus a spunbond, a total of 6 heads of a variety of composite combinations, forming a diversified development mode.

Different products are used, the fiber fineness of spunbonded and melt blown is also different. With the series of products that can adapt to different varieties, users have the choice.

In addition, China textile technology company can tailor and tailor the special configuration that suits users' needs according to the special requirements of users.

The three characteristic is mastering the key core technologies.

The spunbonded and melt blown process is relatively short, and the process flow should be completed in an instant, thus increasing the difficulty of the process.

In this entire production line, there are many key core technologies.

For example, there are many difficulties in the design, manufacture and assembly of die head.

But through many years of practice, China spinning technology has grasped the core technology of key parts, components and parts from the melt pipe to the coat hanger shape, distribution, spinning and laying process.

Of course, some key components also need to be produced by cooperative units.

But regardless of their production or cooperation units, there are strict quality control measures, must meet the design requirements and product standards, so as to ensure the overall technological level of the project.

Four of the characteristics is the proprietary technology of spunbonded and melt blown proprietary technology.

Spunbonded and melt blown production lines have many technical parameters that can not be seen or touched.

Such as the pressure and flow of spinning, the temperature of hot air, wind pressure, flow, polymer material,

,

In terms of crystallization and scientific calculation of spinning speed, China spinning technology has accumulated a large amount of scientific data, and has written into its technical documents, forming a unique technical document system in the process of single machine production, process line forming and engineering completion, such as forming a complete project operation book, installation operation book, maintenance operation book and so on.

These books have clear responsibilities from assistant craftsmen to master craftsmen and project managers.

Equipment is the carrier of technology. Only through process production can we verify the technical level of the equipment.

The successful practice of China spinning technology shows that the non-woven fabric produced by the process line and the complete set of the project can meet the engineering requirements in terms of crystallinity, fiber fineness, evenness and uniformity.

The unit area quality deviation, coefficient of variation, pverse and vertical fracture, strength and antistatic water pressure can meet user requirements.
