Embodiment 1

[0034] 1. Add 140KgPP granules, 50KgPOE elastomer granules and 10Kg whitening masterbatch into the hopper; vacuum pump the mixed and stirred raw materials to the screw through the feeding system for extrusion and melting. The melting temperature of the screw is 180°C to obtain a hot melt ; Filtration, metering and distribution of the hot melt at 230° C., 5 MPa. The hot melt spinning that has been distributed and metered is to spray the silk through the 0.3mm aperture, and cool it through the cooling bellows. The temperature of the cooling bellows is 10°C, and the cooling wind speed is 0.2m / s. The filaments are separated by airflow, and the primary growth filaments are drawn by airflow through the bell mouth of the slit drafter. The airflow drafting speed is 2000m / H, and the fiber with a denier of 1.8 is obtained.

[0035] 2. The obtained polypropylene fiber is divided into wires and laid into a net. In this process, the gas produced by the air compressor pump is passed into th...

Embodiment 2

[0040] 1. Add 137KgPP granules, 59KgPOE elastomer granules and 4Kg whitening masterbatch into the hopper; vacuum pump the mixed and stirred raw materials to the screw through the feeding system for extrusion and melting. The melting temperature of the screw is 180℃~270℃ to obtain Hot melt; filter, measure and distribute the hot melt at 250°C and 10MPa. The hot melt spinning that has been distributed and metered is to spray out the silk through the 0.8mm aperture, and cool it through the cooling bellows. The temperature of the cooling bellows is 20°C, and the cooling wind speed is 1.5m / s. The filaments are divided by airflow, and the primary growth filaments are drawn by airflow through the bell mouth of the slit drafter. The airflow drafting speed is 5000m / H, and the fiber with a denier of 2.2 is obtained.

[0041]2. The obtained polypropylene fiber is divided into wires and laid into a net. In this process, the air compressor will generate gas into the trachea, and the 10.5Kg...

Abstract

The invention discloses a skin-friendly soft nonwoven fabric which comprises the following raw materials in percentage by weight: 90 to 95 percent of polypropylene fiber and 5 to 10 percent of soybeanfiber, wherein the soybean fiber is short fiber, and the length is 1 to 3 cm. The polypropylene fiber is prepared from a polypropylene master batch; the polypropylene fiber is subjected to filament splitting and lapping; the short fiber of the soybean fiber is continuously sprayed onto the polypropylene fiber in the filament splitting and lapping process to obtain a fiber net; the fiber net is subjected to primary hot rolling to obtain a nonwoven fabric; after-finishing is performed on the non-woven fabric to obtain a nonwoven fabric; and the nonwoven fabric is subjected to secondary hot rolling to obtain the skin-friendly soft nonwoven fabric. When being used for a bottom film coating layer of disposable hygienic products, the nonwoven fabric has the characteristics of skin-friendly effects and softness. When the nonwoven fabric is made into baby diapers, the conditions of skin allergy and eczema of a baby can be reduced. The strength, elongation rate, softness and air permeability of the nonwoven fabric are better than those of cotton.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to. Background technique [0002] Soft non-woven fabric is a non-woven fabric material developed in recent years to improve the comfort of disposable sanitary products such as baby diapers, adult incontinence pants and women's sanitary napkins. It is mainly used in the surface layer and bottom film coating layer of disposable sanitary products such as baby diapers, adult incontinence pants, sanitary napkins, etc., which can effectively improve the comfort of users. The base film coating layer non-woven fabric used for disposable sanitary products such as baby diapers / diapers, adult diapers / diapers, and women's sanitary napkins generally needs to be soft and skin-friendly. However, since non-woven fabrics are generally made of PP fibers, when baby diapers are used in contact with the baby's waist and buttocks, due to the delicate skin of the baby and poor resistance, skin ...
