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 the silk through the 0.8mm aperture, and then 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 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 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....

Abstract

The invention discloses a skin-friendly and soft non-woven fabric. The non-woven fabric comprises the following raw materials in weight percentage: 90-95% of polypropylene fiber, 5-10% of soybean fiber; the soybean fiber is short fiber with a length of 1~3cm. The polypropylene masterbatch is made into polypropylene fiber; the polypropylene fiber is divided and laid, and the soybean fiber short fiber is continuously sprayed on the polypropylene fiber during the divided and laid process to obtain a fiber web; the fiber net is first The non-woven fabric is obtained by hot rolling; the non-woven fabric is obtained by finishing the non-woven fabric; the non-woven fabric is subjected to a second hot rolling to obtain a skin-friendly and soft non-woven fabric. The non-woven fabric of the present invention is used for the base film covering layer of disposable sanitary products, which has the characteristics of being skin-friendly and soft, and can reduce skin allergies and eczema of babies when made into baby diapers. The strength, elongation, softness and air permeability of non-woven fabrics are better than those of cloud 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 ...
