Pet Spunbonded Machinery

Pet Spunbonded Machinery is a special nonwoven fabric. It has a high level of strength and elasticity, which makes it suitable for medical and health products (face mask, operation suit, gown, baby pads, and sanitary napkins) and home decoration (linen, curtains, and shoes). Its dimensional stability and resistance to gamma sterilization are also physical properties that other polypropylene spunbond nonwovens do not have. This is what makes PET spunbonded fabric a more versatile material and the reason why it has been widely adopted by many industries, including advertising & printing, automotive, and furniture & mattress.

The process of making spunbonded nonwoven fabrics begins with feeding a block of polyethylene terephthalate (PET) homopolymers into an extruder. The homopolymer is then melted and transferred into a capillary system in the form of endless filaments. The filaments are then bonded together by the application of primary and secondary process air under pressure. The result is a high-strength, highly abrasion-resistant, and soft web with good internal bonding. The resulting web is also extremely stable, which makes it ideal for applications that require an extensive amount of processing (such as cutting and stitching).

Unlike meltblown nonwovens, spunbonded fabrics are produced from the feed distribution channel rather than a die assembly. The web uniformity partially depends on the spinneret, which is made from a single block of metal with several thousand drilled orifices. The design and fabrication of this type of device is expensive, but essential to the success of the process.

After the production of the continuous web, it undergoes a series of post-processing steps, including closure air stretching, calendering, and winding. The final product is then cut to size and packed for delivery. The production of the nonwoven is a labor-intensive and time-consuming process that requires a high degree of technical expertise.

PET spunbonded nonwovens can be further treated to acquire additional traits, such as flame-retardant, fluorescent, hydrophobic, and anti-bacterial. These treatments can be applied during the spinning process or afterward. The fire-retardant treatment retards flammability, typically offering up to grade C-1. The fluorescent treatment adds color, while the hydrophobic treatment allows liquids to pass through it.

The global PET spunbonded nonwovens industry is competitive and includes a large number of international players with large manufacturing facilities in multiple countries. Major players in the market include Kolon Industries, Inc., Unitika Ltd, Avintiv, and Toray Industries, Inc. The major strategies used by these companies are new product launches, mergers & acquisitions, and geographical expansion. They are also focusing on expanding their product portfolios to meet the changing needs of the customers. This will help them strengthen their position in the market and increase their profit margins. This is expected to drive the growth of the industry in the coming years. Moreover, the increasing demand for these products in various industries is expected to further propel the industry. However, the price volatility of raw materials is a major challenge that manufacturers are facing. The price of crude oil is constantly changing, and this can affect the pricing of finished products.
