Super-soft SS (spunbond and spunbond) nonwoven fabric and production process thereof

ActiveCN103132241AAppropriately meet the requirements of tender skinSoft and smoothNon-woven fabricsElastomerMasterbatch
The invention discloses super-soft SS (spunbond and spunbond) nonwoven fabric. The super-soft SS nonwoven fabric is mainly made from, by weight, 55-90 parts of polypropylene, 5-40 parts of elastomer, 1-4 parts of softener and 0.5-1 part of cooling masterbatch. The invention further discloses a production process of the super-soft SS nonwoven fabric. The production process includes the steps of preparing raw materials and auxiliary materials according to the proportion, mixing well, melt-compressing by a screw extruder to obtain viscous flow melt, sending the melt into a melt filter for filtration, allowing the melt to enter a spinning die head, allowing trickle of the melt to be extruded out of spinneret orifices, allowing a drafting air channel to draft and shape the trickle of the melt under the action of process cooling air so as to obtain fiber of certain strength, allowing the fiber to be evenly adsorbed to a forming conveyor belt by a diffusion air channel to form a continuous mesh fiber layer, and rolling the fiber mesh into the nonwoven fabric of certain longitudinal and transverse tension by a hot rolling mill. The SS nonwoven fabric produced according to the formula by the process is smaller than 1.5g in softness, and is as soft and smooth as silk to touch and highly suitable for shell fabrics of baby diapers.

Soft antibacterial and deodorizing baby paper diaper

The invention discloses a soft antibacterial and deodorizing baby paper diaper, which comprises a surface layer, an absorbent core layer and a bottom non-woven fabric, wherein the absorbent core layer comprises a cotton core, a high polymer material and toilet paper; the bottom non-woven fabric comprises a PE film and a non-woven fabric; the surface layer is arranged at the top of the paper diaper and includes an upper surface layer and a lower surface layer; the upper surface layer is taken as a surface layer in the paper diaper and the lower surface layer is a stream guidance layer; the high polymer material is formed by mixing high polymer SAP particles and charred coconut shell according to content proportions of 85-95% of the high polymer SAP particles and 5-15% of the charred coconut shell; the stream guidance layer is made from bamboo fiber spunlace; and the upper surface layer is made from a hot-rolled non-woven fabric which is formed by mixing glue and ES fibers, wherein content proportions of the glue and the ES fibers are as follows: 30-50% of the glue and 50-70% of the ES fibers. The soft antibacterial and deodorizing baby paper diaper is strong in sterilizing and deodorizing capacities and is soft and comfortable; and the soft antibacterial and deodorizing baby paper diaper, when applied to a baby, is comfortable to wear, so that body health can be guaranteed.

Super absorbent resin with high absorbent velocity and preparation method

ActiveCN103360555ANo acute toxicityNon-cytotoxicFreeze-dryingBiocompatibility Testing
Provided are a super absorbent resin with a high absorbent velocity and a preparation method. A polymer and monomer aqueous solution composed of, by weight, 2-10 wt% of PVA, 18-26 wt% of PAAS and 3-9 wt% of AMPS is heated and dissolved. Copolymer gel is synthesized through electron beam radiation crosslinking and grafting. The copolymer gel is then subjected to swelling and immersion cleaning by an immersion cleaning liquid, and then subjected to extraction freezing and freeze-drying to obtain a super absorbent resin. The pH value, normal saline absorbent amount and centrifugal preservation amount of the super absorbent resin have reached international level, and the super absorbent resin is remarkably superior to famous super absorbent resin products (P is less than 0.01) at home and abroad especially in the absorbent amount and the absorbent velocity of triple-distilled water and is in international advanced level. The super absorbent resin has advantages of simple technology, good biocompatibility and safe usage. The super absorbent resin can be widely used in a plurality of fields of medical and health supplies such as uracratia mattresses, infant diapers, woman sanitary napkins and the like, water retention and moisture preservation of agriculture and forestry and the like. The super absorbent resin has great application and development values.

High-strength composite core, preparation method thereof and application of high-strength composite core in baby diapers

The invention discloses a high-strength composite core, a preparation method thereof and application of the high-strength composite core in baby diapers, and relates to the technical field of disposable hygienic products. According to the high-strength composite core and the preparation method thereof, through compounding of PP / PE double-component filament fibers and a high-strength composite fiber net, selection of raw materials of high-crimpness C-type coarse-denier hydrophilic PTT fibers and reasonable matching and common use of super absorbent resin and wood pulp fibers, a processing modeof firstly carrying out thermal hardening and then spraying super absorbent resin / wood pulp mixed powder, innovative design of processing technological parameters, the prepared high-strength compositecore has good toughness, aging resistance, air permeability, moisture penetrability and comfort; the composite core has the advantages of being long in diffusion length, free of hot melt adhesive, high in SAP utilization rate and good in absorption capacity, compared with an existing composite core, the use amount of SAP can be further reduced, and when the composite core is applied to preparation of baby diapers, the fault phenomenon caused by the large amount of urine or the large amount of exercise of babies can be avoided.
