Before choosing baby diaper raw material, it is important to know what it is made from. We’ll discuss SAP, Polypropylene nonwoven, and Sodium polyacrylate hydrogel. Each of these materials has its own advantages and disadvantages. Choosing the right raw material will help you create a quality diaper.


SAP baby diaper raw material is a nonwoven polymer with a high molecular weight and cross-links. The polymer then reacts with water by forming a gel phase. This happens because the polymer’s polarity forces trap hydrogen and water. The presence of electrolytes in the liquid also affects the SAP’s superabsorbent properties. This is why diapers with SAP should never be tested with plain water. Instead, they should be tested with a 0.9% saline solution..

Polypropylene nonwoven

Polypropylene nonwoven diapers are made from three main components: the back/bottom sheet, the absorbent core, and the cover. These three materials are bonded together with adhesives. These adhesives are usually mixtures of oils and resins that are applied in molten form. They are then allowed to cool to create a stronger bond. There are two types of adhesives used in the manufacturing of disposable diapers: construction adhesive and elastomeric adhesive. Construction adhesive is used to glue the nonwoven sheets together, while elastomeric adhesive is used to adhere to the leg and waist elastics. Elastomeric adhesives have higher bonding strength and elasticity and are considered safe for diaper use.

Sodium polyacrylate

Sodium polyacrylate is a super-absorbent polymer that is commonly found in disposable baby diapers. Sodium polyacrylate absorbs water at a rate of 500 to 1000 times its own mass. It is used as an absorbent material in paper diapers and is also used as a water-retaining agent for rocky slopes. This polymer is safe and can be found in small quantities in baby diapers.

The three main parts of a baby diaper are a pad, an absorbent material, and a backing sheet. Each of these components is made of a different raw material. Sodium polyacrylate, or SAP, is produced from synthetic hydrocarbons. These hydrocarbons are screened to remove any salts before being used in baby diapers.

Sodium polyacrylate hydrogel

Sodium polyacrylate hydrogel (SAP) baby diapers are made with a polymer called Sodium polyacrylate. These diapers have several advantages over conventional diapers. They are very absorbent, dry, and rash-protective. They are also widely used in developing countries and have become more affordable.

Sodium polyacrylate is a white, granular powder that quickly absorbs water. Its ability to soak up water is due to the presence of three hydrogen molecules. The granules form a gel when mixed with water. It has a lot of cross-linking and absorbs approximately 600 times its mass in water. Because of its high absorption capacity, sodium polyacrylate is used to make super-absorbent diapers. Sodium polyacrylate is easily destroyed by table salt, which breaks down the gel.

Sodium polyacrylate hydrogel baby diapers are made with two layers: an outer layer of microporous polyethylene that stops urine from leaking through the inner layer; and a second layer of polypropylene that absorbs moisture from the skin. In addition to diapers, sodium polyacrylate is used in other products, including female hygiene products. It is also used in filtration units to separate fuel and water, and in electrical and optical cables to protect them from moisture.

Polyethylene nonwoven

Polyethylene nonwoven baby diapers are composed of three separate parts: a polyethylene bottom sheet, a polypropylene top sheet, and elastics. These pieces are then joined together by heating, gluing, or ultrasonic welding. The cloth diapers may also have Velcro closures or tapes to keep them in place.

Polyethylene has many benefits over other nonwoven fabrics. It is highly breathable, durable, and has excellent anti-tear and anti-pull properties. Furthermore, it is resistant to high temperature. Finally, it is also environmentally friendly. Therefore, polyethylene is a good choice for a wide range of baby diapers, from infant diapers to adult diapers.

Polyethylene nonwoven baby diaper raw material is produced using an additive known as super-absorbent polymer (SAP) or superabsorbent polymer (SAP). This additive is added to baby diapers to improve their absorbency. It reduces the use of wood pulp fibres and increases the retention capacity of the product. It is a form of sodium polyacrylate, which unwinds quickly to absorb liquid.
