Polyester SPH

● Polyester SPH fiber is a three-dimensional structured crimped fiber formed by parallel composite spinning and relaxation heat treatment processing of two polyester compounds with different thermomechanical properties, PTT and PET; SPH is similar to spandex in terms of tensile and elastic properties, and its elastic durability is better than than that of spandex. It also has the advantages of easy dyeing, good color fastness, etc.

● Product usage: mainly used for summer shirt/dress cloth, spring and autumn trouser cloth and dress cloth, etc. It also can be used to produce CEY.

The properties of polyester SPH
Polyester SPH (Superabsorbent Polymer Hydrogel) possesses several key properties that make it a versatile and valuable material in various applications. Some of the properties of polyester SPH include:
1. Absorbency: Polyester SPH exhibits high water absorption capacity due to its three-dimensional cross-linked structure. It can absorb and retain large amounts of water or aqueous solutions.
2. Swelling behavior: When in contact with water or other polar solvents, polyester SPH swells to form a gel-like structure. The degree of swelling can be controlled by adjusting the cross-linking density or the chemical composition of the polymer.
3. Retention capacity: Polyester SPH has excellent water retention capacity, allowing it to retain absorbed water under pressure or in the presence of external forces. This property makes it suitable for applications requiring moisture management, such as in agriculture or personal care products.
4. Biocompatibility: Polyester SPH can be designed to be biocompatible, meaning it is compatible with living tissues and can be used in medical and biomedical applications. Biocompatible polyester SPH can be utilized in wound dressings, drug delivery systems, and tissue engineering scaffolds.
5. Chemical stability: Polyester SPH exhibits good chemical stability, retaining its properties in a wide range of pH values and in the presence of different chemicals. This stability allows it to be used in diverse environments and applications.
6. Environmental sustainability: Polyester SPH can be produced from renewable resources, making it a more environmentally friendly alternative to traditional superabsorbent polymers derived from petrochemicals. Additionally, it can be biodegradable under certain conditions, reducing its environmental impact.
7. Rheological properties: Polyester SPH can exhibit shear-thinning behavior, meaning it flows more easily under applied shear stress. This property is advantageous for applications such as coatings, adhesives, and sealants.
These properties make polyester SPH a desirable material for a wide range of applications, including agriculture, hygiene products, medical devices, packaging materials, and more. The specific properties of polyester SPH can be tailored through modifications in its synthesis, cross-linking density, and chemical composition to meet the requirements of different applications.

The applications of polyester SPH
Polyester SPH has diverse applications across various industries. Some of the common applications of polyester SPH include:
1. Hygiene products: Polyester SPH is widely used in the manufacturing of disposable hygiene products such as diapers, adult incontinence products, and feminine hygiene products. Its high absorbency and retention capacity make it ideal for these applications, providing efficient moisture absorption and containment.
2. Agriculture: Polyester SPH is utilized in agriculture for water management and soil improvement. It can be incorporated into agricultural soil or used as a component in irrigation systems to enhance water absorption, reduce water runoff, and improve moisture retention in the root zone of plants.
3. Medical and wound care: Biocompatible polyester SPH is employed in medical and wound care applications. It can be used in wound dressings to absorb excess exudate, maintain a moist wound environment, and promote wound healing. Polyester SPH can also be incorporated into drug delivery systems for controlled release of medications.
4. Packaging materials: Polyester SPH is utilized in packaging materials, particularly for moisture-sensitive products. It can be incorporated into packaging films or sachets to absorb and retain moisture, preventing spoilage or degradation of the packaged goods.
5. Personal care products: Polyester SPH finds applications in various personal care products such as facial masks, wet wipes, and cosmetic formulations. It provides effective water absorption, moisturization, and improved product performance.
6. Construction materials: Polyester SPH can be incorporated into construction materials such as concrete and mortar to enhance their water retention properties. It helps to improve workability, reduce cracking, and increase the durability of the materials.
7. Environmental applications: Polyester SPH is used in environmental applications such as wastewater treatment and soil remediation. It can absorb and retain water, as well as capture and immobilize certain contaminants, aiding in the purification and remediation processes.
8. Food industry: Polyester SPH is employed in the food industry for moisture management in food packaging, preventing moisture migration and maintaining product freshness. It can also be used in food processing applications, such as in meat processing, to improve moisture retention and enhance product quality.
