fluff pulp

Fluff pulp plays a vital role in diapers. As one of the core absorbent materials, the characteristics of diaper fluff pulp directly determine the performance of diapers. Its fibers can quickly absorb and disperse urine with excellent moisture absorption, and work together with polymer absorbent resin (SAP) to form a powerful absorption system, ensuring that diapers remain dry for a long time and effectively reducing the baby's discomfort. In addition, the mesh structure of fluff pulp brings good breathability to diapers, helps reduce moisture accumulation, thereby preventing red buttocks and diaper rash, and carefully protecting the baby's delicate skin. At the same time, the softness of fluff pulp makes diapers fit the baby's body better, reduces friction, and further improves the comfort of wearing. In terms of structural stability, fluff pulp is closely combined with other materials such as SAP and non-woven fabrics to form a stable absorption layer. This structure not only effectively prevents the diaper from deforming or bunching up after absorbing water, but also maintains the integrity and high absorption efficiency of the diaper.

Treated fluff pulp (treated wood pulp) and untreated fluff pulp (untreated wood pulp) are significantly different in many dimensions. Fluff pulp, whether it is virgin wood pulp or recycled wood pulp (such as regenerated pulp), has been chemically or mechanically treated, a step designed to remove impurities and improve the purity and separation of fibers. In contrast, untreated fluff pulp is extracted directly from wood without any further treatment, so it contains more impurities and incompletely separated fibers. In terms of performance, fluff pulp shows higher absorption performance, its fiber structure is uniform, its air permeability is good, and it is soft and delicate, all of which help to improve the comfort of the product. At the same time, fluff pulp is more closely integrated with other materials, and its structural stability is strong, which can effectively prevent diapers from deforming or lumping after absorbing water. In contrast, untreated fluff pulp has poor absorption performance, air permeability and softness, and its structural stability is also insufficient. In terms of application and market demand, fluff pulp is widely used in high-end diapers, sanitary products and other fields due to its excellent performance, meeting consumers' demand for product quality and comfort. Untreated fluff pulp is mostly used in low-end or low-cost products, but as consumers' requirements for product quality and environmental protection continue to increase, its market demand may gradually decrease.

Diapers are a must have item for modern babies. The core of diapers directly affects the product quality such as water absorption and breathability. At present, there are four main types of diaper cores: Wood pulp core (fluff pulp): It is a mixture of wood pulp and polymer water-absorbing resin, without stratification. Its advantage is that wood pulp fibers can effectively comb urine into the core, and polymer materials lock urine to keep the surface dry. However, the presence of wood pulp leads to easy lumps and fractures. Despite this, its excellent urine combing performance is still adopted by major international brands. The thinness is average, the water absorption and breathability are good, the softness is moderate, and the lumps and fractures are more obvious. Dual core (second-generation core): The structure is similar to sheet stacking, combining the super absorbent polymer  guide layer and the wood pulp layer, optimizing the water absorption and structural design. The wood pulp layer combs urine, and the polymer layer absorbs, with strong water absorption capacity and large water absorption. However, the stacking structure plus non-woven fabric is prone to soft lumps. The thinness is average, the water absorption is excellent, the air permeability is slightly weak, the softness is good, and the problem of lumping and faulting is moderate. Glue core (third generation core): It is mixed with hot melt adhesive, non-woven fabric and polymer absorbent resin, and is layered. The polymer ensures the absorption amount, and the glue bonding remains flat and does not clump. However, after absorbing water, the whole expands, the air permeability is poor, and it may cause discomfort to the baby. Insufficient technology may cause the glue to smell or harden, and the cost is high. The thinness is average, the water absorption is good, the air permeability is very poor, the softness is moderate, and the problem of lumping and faulting is less. Braided core: It is woven with breathable, flexible, and moisture-proof materials, filled with polymer absorbent primers, and has a special surface layer on the outside. The non-laminated structure is thin and not easy to clump and fault, and the diversion effect is good. But the cost is high. The thinness is excellent, the water absorption, air permeability, and softness are all good, and the problem of lumping and faulting is less. To sum up, various core structures have their own advantages and disadvantages, and parents can choose suitable products according to their baby's needs and budget.
