Problems solved by technology

2) Poor local ventilation: further restricts the volatilization of moisture, and can indirectly promote the occurrence of allergic reactions
[0003] Most of the existing technologies only start with improving the dryness and air permeability of paper diapers to prevent the occurrence of diaper rash. Although they have certain effects, they still cannot effectively prevent the occurrence of diaper rash.

Embodiment 1

[0023] The preparation of the finishing agent: Put 46kg of deionized water in a conventional liquid washing pot, heat to 70°C, start stirring, the stirring speed is 100 rpm, and 18kg of cetearyl ether-20, 10kg are sequentially added during stirring. Didecyl dimethyl ammonium chloride (active substance content 70%), 12kg laureth-9, 6kg sucrose octasulfate, 3kg bisabolol, 2kg pentanediol, 3kg 1,3-propanediol; Maintain 70°C and continue stirring for 30 minutes to fully dissolve all materials; turn on cooling water, cool to normal temperature; discharge.

[0024] The finishing of the spunbonded non-woven fabric: the finishing is implemented using non-woven fabric padding, drying finishing equipment and technological processes known in the art. Add 98 kilograms of deionized water and 2 kilograms of the finishing agent into a conventional batcher, stir and mix uniformly under normal temperature conditions to make a diluted finishing agent. The spunbond non-woven fabric weighing 20 gra...

Embodiment 2

[0025] Example 2. Finishing of the spunbond non-woven fabric

[0026] The finishing is implemented using non-woven padding, drying finishing equipment and technological processes known in the art. Add 98 kilograms of deionized water and 2 kilograms of the finishing agent into a conventional batcher, stir and mix uniformly under normal temperature conditions to make a diluted finishing agent. The spunbond non-woven fabric weighing 25 grams per square gram is finished with the diluted finishing agent. The specific process parameters are: linear speed 80 m / min; one dipping and one rolling; the roller spacing is set to 0.25 mm, so that the adsorption amount of the diluted finishing agent on the spunbonded non-woven fabric is nothing by weight percentage. 20±1% of the weight of the woven fabric; dried at 125℃.

Embodiment 3

[0027] Example 3. Three kinds of surfactants synergy experiment (three-factor three-level orthogonal experiment)

[0028] According to the preliminary test results, the design level factor table is shown in Table 1.

[0029] Table 1. Level factor table

[0030]

[0031] The finishing agent formula is designed according to the above-mentioned level factor table, and the dosages of the three surfactants are respectively set. The other components except deionized water and their dosages remain unchanged, and the deionized water is added to 100%; according to Example 2 According to the method shown, 9 groups of finished spunbond non-woven fabrics were obtained, and the first penetration time, the fifth penetration time and the longitudinal softness were measured respectively, and the corresponding orthogonal test data was calculated.

[0032] 1. Results and analysis of orthogonal test for the first penetration time:

Abstract

The invention relates to a spun-bonded non-woven fabric with a function of preventing diaper rashes. The spun-bonded non-woven fabric is mainly used for surface layers of disposable nappies. The function of preventing the diaper rashes of the spun-bonded non-woven fabric is realized by finishing with a special finishing agent which comprises the following components in percentage by weight: 18% of cetyl stearyl alcohol ether-20, 10% of didecyl dimethyl ammonium chloride (containing 70% of active matters), 12% of polyoxyethylene lauryl ether-9, 6% of sucrose octasulfate, 3% of bisabolol, 2% of pentanediol, 3% of 1,3-propylene glycol and the balance of deionized water. The invention also discloses a finishing method of the spun-bonded non-woven fabric.

Description

technical field [0001] The invention relates to a spun-bonded non-woven fabric with the function of preventing diaper rash. The spunbonded nonwoven fabric is mainly used for the surface layer of disposable diapers. Background technique [0002] Disposable disposable diapers have brought a lot of convenience to consumers, but consumers are prone to skin inflammation in contact with diapers (perineum, buttocks, lower abdomen and inner thighs) during use, that is, diaper rash. For erythema, papules. Diaper rash, also known as "diaper dermatitis", "ammonia dermatitis", is a non-infectious skin inflammation, which is classified as "contact dermatitis", "physical dermatitis" and "allergic dermatitis" in clinical medicine (type IV allergy) category. Regarding the etiology and pathology of diaper rash, the medical community has not yet had a clear conclusion. It is generally believed to be the result of the combined effects of the following factors: 1) Too much local humidity: es...
