Winter diapers

Challenging care in low temperatures

The cold wind in winter is like a bunch of small knives, cutting every inch of exposed skin. For delicate babies, such weather conditions are even more challenging. Diapers, as the "little guardians" of babies, often encounter difficulties in low-temperature environments and have become a source of worry for many parents during the winter. 

The "trick" of low-temperature diapers

In winter, there is a significant temperature difference between indoors and outdoors, and the baby's delicate skin becomes extremely sensitive during the alternation of hot and cold. Diapers in this particular season are like facing a difficult test. In low-temperature conditions, the drawbacks of traditional diapers gradually become apparent. 

The water absorption performance was the first to be affected. The material that was originally capable of quickly absorbing urine became "less responsive" at low temperatures. The urine could not be absorbed in time and remained on the surface of the diaper for a long time, coming into close contact with the baby's skin. This significantly increased the risk of skin irritation, and problems such as red buttocks also occurred. 

The ventilation also suffers greatly. Low temperatures cause the material of the diaper to contract, and the original ventilation holes become smaller or even partially closed, preventing air from flowing smoothly. The baby's bottom is like being enclosed in a tightly sealed "small cage", feeling stuffy and humid, providing a breeding ground for bacteria. 

Moreover, low temperatures also make the touch of the diaper less pleasant. The originally soft and skin-friendly material becomes stiff and rough. When the baby moves, the friction with the skin increases, which can easily cause abrasions to the baby's delicate skin and make the baby feel uncomfortable. 

The Material of Diapers Unveiled 

Modern disposable diapers are not helpless. Their ingenious multi-layer structure design is like creating a "warm armor" for the baby, and the selection of materials for each layer is of vital importance. 

Surface Skin-Adhesive Layer

The surface skin-adhesive layer serves as the first line of defense for the baby's skin. High-quality diapers will use special non-woven fabric that is added with hydrophilic granules. This material enables urine to spread quickly on the surface, preventing local accumulation and reducing irritation to the skin. At the same time, it can maintain a certain level of dryness, keeping the baby's skin in a comfortable state. 

Conduit diffusion layer

The conduit diffusion layer is like the "traffic controller" of urine. It adopts a unique fiber arrangement and is combined with ultra-soft masterbatch, which can quickly guide urine to various parts of the absorption layer, preventing excessive concentration of urine in a certain area and ensuring uniform absorption. Moreover, this design can effectively reduce urine backflow, keeping the baby's skin away from moisture. 

Core Absorption Layer

The core absorption layer is the "heart" of a diaper. The ingenious combination of polymer absorbent resin and felt pulp gives it an extremely strong water absorption capacity. In winter, some advanced diapers will add antibacterial granules to inhibit bacterial growth while absorbing urine, ensuring the health of the baby. There is also a special fragrance granule that can release pleasant scents after coming into contact with urine, neutralizing odors and keeping the baby fresh at all times. 

Anti-leak Sealing Layer

The anti-leak sealing layer is the "loyal guardian" that prevents urine from leaking to the sides. It is made of elastic non-woven fabric enhanced with soft cotton granules, featuring excellent flexibility and resilience. It can closely fit the baby's legs and maintain a sealed state even during the baby's movements, effectively preventing urine from seeping out and avoiding staining of clothes and bed sheets. 

Underlying breathable membrane

The underlying breathable membrane is the "breathing channel" of the diaper. The application of the silk soft masterbatch enables the PE membrane to form tiny breathable holes, which can not only prevent urine leakage but also allow air to flow freely. In winter, it can ingeniously balance ventilation and warmth, preventing cold air from directly blowing on the baby's skin, while accelerating the evaporation of moisture and keeping the baby's bottom dry. 

The meticulous dedication of Rizhe color masterbatch

With the advancement of materials science, the material of disposable diapers is undergoing a transformation from "basic functions" to "excellent experiences". In this change, masterbatch technology plays a crucial role. As the "genetic editor" in non-woven fabric production, functional masterbatches can inject specific properties into the fibers during the spinning process - whether it is long-lasting antibacterial ability, gentle fragrance, or excellent hydrophilic characteristics, all can be achieved at the source. 

At Yancheng Ruize Color Masterbatch Co., Ltd., we are well aware that behind every high-quality diaper lies the meticulous craftsmanship of materials science. As a professional manufacturer of special masterbatches for hygiene materials, Ruize has carried out refined softness effect designs and functional developments for each part of diapers, thereby endowing non-woven fabric with greater product value. 

For example, for waistbands, we use a special soft masterbatch: The waistband non-woven fabric produced with this masterbatch has a soft and smooth texture, with great elasticity and potential. 

Side wings use soft special granules: The non-woven fabric on the side wings, after adding our special granules, exhibits remarkable softness properties, effectively reducing friction with the baby's skin and lowering the likelihood of red bottom syndrome. Moreover, its urine-repellent effect is excellent, preventing side leakage of urine and keeping the baby's skin dry, allowing mothers to feel more at ease. 

Special masterbatch for the surface layer of non-woven fabric: The surface layer of non-woven fabric directly comes into contact with the baby's skin, and its performance requirements are extremely high. Our special masterbatch not only endows the non-woven fabric with ultra-soft and ultra-flexible characteristics, but also gives it certain absorbency, which can assist the core layer of the diaper to accelerate the absorption speed of urine. At the same time, the quick-drying effect can effectively prevent urine back-permeation, reduce the chance of bacterial growth, and safeguard the health of the baby.
