Pillow Core Lining: Neglected Pillow ‘Health Line’
Many consumers only focus on the softness of the fabric and the filling material of the pillow core when choosing a pillow, but overlook the key component of the pillowcase lining. As the core barrier that isolates the pillow core from the outside, blocks sweat and dandruff infiltration, and inhibits the growth of mites and bacteria, the lining material directly determines the hygiene level and service life of the pillow. Spunbond non-woven fabric, with its advantages of breathability, flexibility, and excellent barrier properties, has become the mainstream material for pillowcase liners.
However, the quality of products on the market varies greatly: inferior liners are prone to breakage, chip shedding, and bacterial growth, while high-quality liners are durable, clean, and protect sleep health. Liansheng technical experts point out that the quality of a good pillow requires half of it to be hidden in the inner lining, and mastering scientific identification methods is necessary to avoid the trap of inferior spunbond fabric.
Liansheng Experts Teach Identification Hand in Hand
（1） Appearance: distinguish uniformity and purity
High quality pillowcases made of spunbond fabric should first consider the texture of the fabric surface. Uniform color, pure white and warm without dullness, no yellow spots, black spots, or impurities, indicating the use of brand new PP polypropylene pellets, without doping with recycled materials; The distribution of fibers on the fabric is dense and flat, without holes, fiber leakage, or uneven thickness.
The transparency is consistent, and the hot-rolled points are regular diamond shaped or dot shaped, with uniform bonding and no detachment. Poor quality spunbond fabric has a gray and dark color, sparse and uneven fabric surface, intermittent light transmission, blurry or missing hot rolling points, and is mostly processed from recycled materials, which are prone to damage and dirt accumulation.
（2） Touch sensation: judge flexibility, test skin friendly
Touch is an intuitive way of identification. High quality spunbond fabric is soft, not stiff, delicate, and not rough. It fits the skin without itching, and has both toughness and elasticity. After rubbing, it does not wrinkle, harden, or shed fibers. Poor quality fabrics are either hard, brittle, and prone to cracking, with a harsh sound when rubbed, or too loose and unsupported, easily deformed by gentle pulling. Long term use can cause friction, pilling, and shedding of debris, blocking the pillow core or irritating the respiratory tract. Liansheng Technology reminds that the inner lining of pillowcases should be in close contact with the skin daily, and skin friendly flexibility is the basic standard.
（3） Performance testing: testing strength, testing protection
Stretching and Tearing Test: Pull horizontally and vertically with both hands, high-quality spunbond fabric has high tensile strength and is not easy to tear. The fibers at the torn area are continuous and there is no powder falling off; Poor quality fabric breaks easily when pulled, with loose and falling debris at the fracture point, indicating low fiber purity and substandard craftsmanship.
Barrier and Leak Prevention Test: Drop a small amount of water on the fabric surface. High quality fabric can temporarily block liquid penetration, prevent sweat and saliva from seeping into the pillow core, and maintain breathability without stuffiness; Poor quality fabric seeps quickly or is completely impermeable, which can easily cause mold and odor in the pillow core.
Odor safety testing: Products that meet the GB 18401 safety standard are those that have no pungent odor or plastic odor when smelled closely; Spunbond fabrics with odors may contain harmful substances such as formaldehyde and heavy metals, which can harm skin and respiratory health.
The “hard standard” of high-quality pillowcases made of spunbond fabric
Liansheng technical experts combine industry standards and pillowcase usage scenarios to summarize three core indicators and accurately target high-quality products:
（1） Weight meets the standard: 30-50g/㎡ is the golden range
The inner lining of the pillowcase should balance lightness and durability, with a weight of 30-50g/㎡ being the optimal weight. Low weight makes it easy to break and has poor barrier properties; If the weight is too high, it will be heavy and not breathable, affecting sleep comfort. The weight deviation rate of high-quality products is controlled within ± 5%, and the thickness is uniform and consistent.
（2） Functional adaptation: anti mite and antibacterial+hygienic and clean
The preferred choice for healthy pillow liners is anti mite and antibacterial modified spunbond fabric, which has a bacteriostatic rate of ≥ 90% against Staphylococcus aureus and Escherichia coli, and a dust mite repellent rate of ≥ 90%, reducing allergens from the source. At the same time, it needs to be free of fluorescent whitening agents and harmful dyes, meet the safety standards for infants and young children, and be suitable for use by mothers, infants, and people with sensitive skin.
（3） Process compliance: Hot rolled firmly+no harmful substances
Adopting precision hot rolling technology, the fibers are firmly bonded, and there is no delamination or deformation after washing; The entire production process is solvent-free and residue free, passed through OEKO-TEX ® Certification, compliance with formaldehyde and pH values, and elimination of chemical irritation. Liansheng spunbond fabric adopts a new pellet+closed-loop production process, strictly controlling the quality from raw materials to finished products, and adapting to the needs of high-end pillowcases.
Stay away from the three major traps of inferior spunbond fabric
Recycled materials are used to impersonate brand new materials: they have a dull appearance, a strange odor, and may cause powder to peel off. Long term use can easily lead to skin allergies, so they are definitely not recommended.
Virtual label function without certification: only verbally claiming antibacterial and mite prevention, without third-party testing reports, the function is not guaranteed, and a testing certificate is required for purchase.
Thin cut corners: insufficient weight, rough craftsmanship, seemingly cheap, but actually easy to break and damage, which actually shortens the service life of the pillow.
Choose the right high-quality lining to unlock a new experience of healthy sleep
Although the inner lining of the pillowcase may not be eye-catching, it is an “invisible guardian” that safeguards sleep hygiene. High quality spunbond fabric lining can not only extend the service life of pillows, but also block pollutants, inhibit mites and bacteria, making sleep cleaner and more comfortable. As a professional manufacturer of spunbond nonwoven fabrics, Liansheng has been deeply involved in the field of home textile lining for many years. With new raw materials, precision technology, and rigorous testing, Liansheng creates high-quality spunbond fabrics that are suitable for pillowcases, helping the industry upgrade and protect consumer health.
Following the identification methods of Liansheng technical experts, we carefully examine, touch, test, and verify the indicators to easily avoid inferior products. We select the right high-quality pillowcase lining to ensure a worry free sleep every night.
