OEM Cushion Factory: Materials and Performance of Memory Pillows

　　A memory pillow is a type of pillow made from slow-rebound material. Its purpose is not to enhance memory; rather, it helps maintain the natural shape of the head and neck by conforming to the contours formed by regular use. What material is a memory pillow made of? Let’s analyze this together.

　　Memory pillows are made from memory foam, an open-cell material developed in the 20th century that offers warmth and pressure relief; it is also referred to as a warm-and-pressure-relieving material. Memory foam is a type of polyurethane foam, and freshly manufactured pieces may have a noticeable odor. When you purchase one, you can usually smell the pillow’s scent. A high-quality memory pillow will have a mild, non-irritating aroma.

　　When it comes to memory pillows, the higher the density, the better the quality. Memory pillow densities typically range from 30D to 120D. A simple way to assess density is by weighing the pillow: compare several pillows of similar standard sizes and choose one with a density that suits your needs. Generally, high-quality adult memory pillows weigh over 1 kg and offer good density. However, don’t rely solely on weight when making your selection—also consider whether the materials are imported, which country or company imported them, the manufacturing process used, and the overall craftsmanship, as all these factors influence the pillow’s density.

　　1. Excellent protective performance and outstanding chemical resistance: It provides chemical inertness and effective liquid barrier protection against most acids, bases, and salts. The porous material exhibits good breathability, as its fine fibers effectively prevent penetration by liquid water, oils, and other liquids, while maintaining excellent waterproofing and breathability.

　　2. Anti-permeation performance against solid particles: The unique physical structure completely blocks even the tiniest mites and dust, preventing penetration. Bacterial barrier performance: Suitable for packaging sterile medical products. Low linting: Highly durable and lint-free.

　　3. High strength and excellent dimensional stability: It is easy to process and does not absorb water, so its dry and wet strengths remain unchanged. Due to the inherent properties of the material, the label’s performance is virtually unaffected by changes in humidity. Under constant temperature conditions, it maintains good dimensional stability across a relative humidity range of 0% to 100%. It retains toughness and elasticity down to –73°C, begins to shrink at 118°C, and starts to melt at 35°C. Therefore, the heating temperature should not exceed 79°C. To prevent deformation, this textile is not recommended for ironing. Additionally, it exhibits outstanding fold resistance, withstanding more than 20,000 repeated folding cycles, making it highly durable and long-lasting.

The memory foam pillow’s core should not be exposed to direct sunlight or washed in a washing machine, as this can damage the pillow’s structure and shorten its lifespan. During everyday use, keep the product dry and well-ventilated, and air it out regularly. The core should be vacuumed once a month or gently beaten by hand. If the pillow becomes damp, promptly blot away the moisture with a towel and allow it to air-dry in a well-ventilated area.
