How is non woven fabric made

Non woven fabric are also known as non-woven fabrics. The raw materials used are mainly polyethene and polypropylene plastic particles, which are by-products produced when refining petroleum. Short fibers or filaments are obtained by high-temperature melting, spinning and other processes, and then rubbed. , cohesion, bonding, or a combination of these methods are oriented or randomly arranged to produce sheets, webs or batts, which are called "nonwovens" because they do not need to be woven but have the appearance and certain properties of cloth. 


The production of non-woven fabrics mainly includes the manufacture of substrates, post-processing and other links, including fiber preparation, web formation, reinforcement, and post-finishing. It is connected to form a net, and then reinforced by spun lace, acupuncture or hot rolling, etc., and finally made into a non-woven fabric after finishing. Downstream enterprises further process non-woven materials to form surgical gowns, sanitary napkins, diapers, wet wipes and other products, which are sold to end consumers. The upstream of the nonwovens industry is mainly the chemical industry, and the downstream mainly includes product companies or terminal brands in different fields such as medical and health care, personal care, engineering, and automotive interiors.


According to the different subdivision process, the nonwovens industry can be divided into spunbond, needle punching, spunlace chemical bonding, thermal bonding and other subdivisions. The nonwovens produced by different raw materials and processes have different properties, so There are also differences in the areas of downstream applications. For example, spunbond nonwovens have high strength, high-temperature resistance, and poor hand feel, and are used in medical protective clothing, packaging cloth, luggage cloth, automotive interiors, etc.; spunlace nonwovens have the characteristics of breathability, softness, moisture absorption, and high strength. It can be used in medical materials, cotton pads, wet wipes and other products.


The raw materials of non-woven fabrics mainly include polypropylene (polypropylene), polyester (polyester), viscose fiber, acrylic fiber and polyamide fiber. Different proportions of various raw materials will affect the characteristics and uses of non-woven fabrics.

How to Hang a Suspended Ceiling From Steel Beams

The suspended ceiling hangs under the roof or floor structure above, hiding ugly mechanical and electrical equipment from the view, while also allowing you to easily reach these equipment as needed.While wooden frames usually support such ceilings, in rooms where metal frames are used instead of traditional wood, you can also hang ceilings from steel beams.Hanging the ceiling from the beam requires you to use a special clip to connect the support line to the beam without compromising its structural integrity.Measure 4 inch down from the bottom of the lowest beam, pipe or pipe in the ceiling space.If you plan to use panel fluorescent lamps in your ceiling, add an additional 2 inch to this measurement.Make a mark on the wall indicating the location of the facade.Set up a laser level to extend the mark you made on the wall to the entire wall length.Draw a chalk line on the wall to mark the position.Mark all four walls repeatedly with chalk lines indicating the height of the ceiling.Instal

Importance of Calibration Service, Material Testing

When it comes to Calibration services, genuine service providers offer full recall system and data sheets for all items calibrated. Service needs to be instrument specific. With the advent of technology, Calibration service has seen a tremendous change and has gone through various phases to get the top quality. Calibration is a great deal for industrial purpose. It makes sure that products are manufactured as per specification. It also checks the competence level of technically valid results. The calibrated measuring instrument helps in checking the quality and valuation of the product. In cases of electronic equipment, it is essential to calibrate instruments to keep a check on quality and performance. Calibration facilitates in improving measurement abilities. Calibration service can be manual or automated.  textile testing equipment manufacturers Material Testing machines are available for a wide variety of industries including materials testers for plastics, textiles, adhesives, fi

Level Measurement Solutions

Makeup water treatment is an important component of steam generation. It is the means to resupply the system with water suitable for boiler and other operations that, was lost in the cycle.The steam generation cycle, level control for the water treatment process is not necessarily about efficiency, but rather, accuracy, reliability and safety, while providing proper inventory management to ensure chemical and makeup water supply meets demand. The focus is on the chemical component of the makeup water treatment since it presents difficulties for level technologies that may work perfectly on non-chemical applications related to the water treatment process or those with limited variations in the contents of the vessel's vapor space. Although important measurements such as ammonia, acid, caustic and other chemical storage tanks are not difficult level applications by any stretch, small nuances in how the vessels are monitored relative to level technology can have a dramatic effect on t
