Description
Technical Field
The utility model belongs to the technical field of the non-woven fabrics technique and specifically relates to do not hinder hot-blast non-woven fabrics of skin.
Background
The hot-air non-woven fabric has a plurality of advantages: 1. the quality of the hot air non-woven fabric is light: the hot-air non-woven fabric mainly takes polypropylene resin as a production raw material, the specific gravity between the materials is only 0.9, the production material of the hot-air non-woven fabric is only three fifths of that of cotton, and the product has high bulkiness and good hand feeling. 2. The soft comfort level of hot-blast non-woven fabrics is extremely strong: the hot-air non-woven fabric is composed of fine fibers and is formed by bonding through a light-spot hot melting technology. The finished hot-air non-woven fabric is moderate in softness and extremely comfortable. 3. The hot-air non-woven fabric has good water-repellent and air-permeable properties: as the production material of the hot-air non-woven fabric is polypropylene, the section of the material does not absorb water, the water content is almost zero, the finished product of the hot-air non-woven fabric has excellent water repellency, the internal composition of the product is composed of 100% of fibers, the product has porosity and excellent air permeability, and compared with other products, the dry and comfortable cloth surface can be more easily kept. 4. The hot air non-woven fabric has good non-toxicity and non-irritation: the hot-air non-woven fabric is processed and produced by adopting composite FDA food-grade raw materials, does not contain other chemical components, and has stable performance, no toxicity and no peculiar smell.
For these reasons, many infant diapers use a hot air nonwoven fabric as a raw material. But long-term practice shows that: paper diapers made with through-air nonwovens are more prone to develop red rash (commonly referred to as red buttocks) in infants than cotton products. The reasons can be roughly attributed to: polypropylene is a non-woven fabric fiber raw material with a lower melting point, in order to enable the non-woven fabric to be more white or have functions of fragrance and the like, ingredients such as spices, flame retardants, whitening agents, fluorescent agents and the like are added into the polypropylene in a molten state by some manufacturers, so that the hot-air non-woven fabric has the advantages of increased hardness, certain irritation and increased probability of skin irritation.
Disclosure of Invention
Not enough to prior art, the utility model provides a be difficult to amazing hot-blast non-woven fabrics of baby's butt.
The technical scheme of the utility model is that:
the hot air non-woven fabric without hurting the skin is characterized in that: the skin-friendly and environment-friendly composite membrane comprises a skin-friendly layer, a polypropylene functional layer, an adjusting layer and a reinforcing layer, wherein the polypropylene functional layer is arranged on the bottom surface of the skin-friendly layer;

Specifically, the weight ratio of the polypropylene fibers to the liquorice fibers in the skin-friendly layer is 3:1, and the liquorice fibers cannot be bonded into cloth because of the lack of hot-melt adhesive property, but can be bonded into cloth by mixing the low-melting-point polypropylene fibers in hot air, namely, the heat-seal non-woven fabric.
Specifically, the polypropylene fiber of the polypropylene functional layer is flame-retardant polypropylene fiber, and the preparation method of the flame-retardant polypropylene fiber is to add an acrylic acid halogen-free flame retardant in a polypropylene melting state, stir the mixture uniformly, and perform spinning to form the fiber. See also chinese patent CN201520615343, a degradable, flame retardant nonwoven fabric for surgical gowns. The benefits of this are: preventing direct incineration disposal after household use.
Specifically, the weight ratio of the chitin fibers to the modified polyethylene fibers in the adjusting layer is 1:1, and the two fibers are made into the non-woven fabric by a spunbond method.
Specifically, the weight ratio of the high elastic fiber to the CoolMax fiber composite fiber in the reinforcing layer is 1:1, and the two fibers are made into the non-woven fabric by using a spunbond method.
Specifically, the thicknesses of the skin-friendly layer, the polypropylene functional layer, the adjusting layer and the reinforcing layer are respectively 0.5 mm, 1 mm, 0.3 mm and 0.2 mm, and are 2 mm in total, so that the diaper cannot be too thick, and is suitable for being made into the top surface (the side which is propped against the buttocks of a baby) of the diaper.
Specifically, the skin-friendly layer, the polypropylene functional layer, the adjusting layer and the reinforcing layer are fixedly connected in a needling mode.
The utility model has the advantages that: the stimulation of the artificial fiber to the tender skin of the infant is relieved through the liquorice fiber (components such as glycyrrhetinic acid and the like), and the probability of the red butt of the infant is reduced; be provided with the regulating layer in the polypropylene bottom surface, the utility model discloses the preparation is called behind the disposable diaper, its below is exactly the water absorbent resin who is used for absorbing moisture, the regulating layer of here can hold back a small amount of aqueous vapor when water absorbent resin absorbs the aqueous vapor in a large number, make the air in the diaper parcel scope can not too dry, and after the water absorbent resin inflation that absorbs water, the regulating layer can absorb a certain amount of aqueous vapor, make the air in the diaper parcel scope can not be moist fast, make air humidity be fit for baby's skin, of course, its absorbed dose is very limited, and also should change disposable diaper after the water absorbent resin saturation, the regulating layer only plays the regulation of certain degree as early as possible, the water absorption performance of disposable diaper can not lengthen by a wide margin. The reinforced layer improves the anti-pulling capability of the utility model through two kinds of strong and tough fibers.
