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

[0022] Preparation of the finishing agent: put 46kg of deionized water in a conventional liquid washing pot, heat to 70°C, start stirring at a stirring speed of 100 rpm, and add 18kg of cetearyl ether-20 and 10kg of cetearyl ether in turn during stirring Didecyldimethylammonium chloride (active substance content 70%), 12kg laureth-9, 6kg sucrose octasulfate, 3kg bisabolol, 2kg pentanediol, 3kg1,3-propanediol; Maintain 70°C and continue to stir for 30 minutes to fully dissolve all materials; turn on cooling water and cool to room temperature; discharge.

[0023] Application of the finishing agent: finishing is carried out by adopting non-woven fabric padding and drying finishing equipment and technological process known in the art. Add 98 kg of deionized water and 2 kg of the finishing agent into a conventional batching device, stir and mix evenly under normal temperature conditions to make a diluted finishing agent. Finish the spun-bonded non-woven fabric with a square g...

Embodiment 2

[0024] Embodiment 2. the application of described finishing agent

[0025] The non-woven fabric padding, drying and finishing equipment and process known in the art are used to implement the finishing. Add 98 kg of deionized water and 2 kg of the finishing agent into a conventional batching device, stir and mix evenly under normal temperature conditions to make a diluted finishing agent. Finish the spun-bonded non-woven fabric with a square gram weight of 25 grams with the diluted finishing agent. The specific process parameters are: a line speed of 80 m / min; one dipping and one rolling; the roller spacing is set to 0.25 millimeters, so that the adsorption amount of the diluted finishing agent on the spunbonded nonwoven fabric is no 20±1% of the weight of the spun fabric; dry at 125°C.

Embodiment 3

[0026] Example 3. Three kinds of surfactant synergistic experiments (three factors and three levels of orthogonal experiments)

[0027] According to the preliminary test results in the early stage, the design level factor table is shown in Table 1.

[0028] Table 1. Table of horizontal factors

[0029]

[0030] The finishing agent formula is designed according to the above-mentioned level factor table, and the dosages of three kinds of surfactants are set respectively, and other components and dosages thereof are constant except deionized water, and deionized water is added to 100%; according to Example 2 According to the method shown, 9 groups of finished spunbonded nonwoven fabrics were obtained, the first penetration time, the fifth penetration time and the longitudinal softness were measured respectively, and the corresponding orthogonal test data were calculated.

Abstract

The invention relates to a spun-bonded nonwoven finishing agent with a function of preventing diaper rashes. The finishing agent is mainly used for finishing surface-layer spun-bonded nonwoven non-woven fabrics of disposable diapers. The finishing agent comprises the following raw materials: 18wt% of spermaceti wax stearyl alcohol ether-20, 10wt% of bis-decyl-dimethyl ammonium chloride (including 70wt% of active substances), 12wt% of polyoxyethylene lauryl ether-9, 0.6wt% of sucrose octasulfate, 3wt% of bisabolol, 2wt% of pentanediol, 3wt% of 1,3- propylene glycol, and the balance being deionized water. The invention further discloses a preparation method and an application process of the finishing agent.

Description

technical field [0001] The invention relates to a finishing agent for spun-bonded non-woven fabrics with the function of preventing diaper rash. The finishing agent is mainly used for finishing the spun-bonded non-woven fabrics on the surface layer of disposable paper 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 ...
