Problems solved by technology

[0003] Traditional nonwoven fabric softeners are mainly emulsions, which require an additional process after the fabric stage to post-treat them, resulting in complex processes and high energy consumption
Moreover, there are still disadvantages such as high addition of polypropylene fiber soft masterbatch and poor softening effect in the current non-woven fabric preparation process.

Embodiment 1

[0038] The preparation method of polypropylene non-woven soft masterbatch material: add styrene type block copolymer and silicone type softener to a high-speed mixer and stir, make them fully mixed, and then let stand until the silicone type softener is removed. After complete absorption, add polypropylene, compatibilizer and antioxidant to it for stirring and mixing, and finally add lubricating softener. After mixing evenly, it was transferred to an extruder with a length-diameter ratio of 48 twin-screw and a total of 12 barrels for melt extrusion and granulation. The barrel temperature is set as follows: the second barrel temperature is 135°C, the third barrel temperature is 210°C, the fourth barrel temperature is 200°C, the fifth barrel temperature is 200°C, and the sixth barrel temperature is 200°C. The barrel temperature is 190°C, the seventh barrel temperature is 190°C, the eighth barrel temperature is 185°C, the ninth barrel temperature is 185°C, the tenth barrel temper...

Abstract

The invention discloses a polypropylene non-woven fabric soft master batch material as well as a preparation method and application thereof. The polypropylene non-woven fabric soft master batch material comprises the following components: polypropylene, a styrene block copolymer, an organic silicon softener, a lubricating softener and a compatilizer, and optionally comprises an antioxidant. The prepared polypropylene non-woven fabric soft master batch product is good in flexibility, and the non-woven fabric prepared from the polypropylene non-woven fabric soft master batch product is soft in touch, high in filling power, not prone to fuzzing, comfortable, skin-friendly and good in rebound resilience. The polypropylene non-woven fabric soft master batch product prepared by the invention is high in effective concentration, small in addition amount in the non-woven fabric and capable of being directly added in a fabric forming process, so that the prepared non-woven fabric is good in uniformity. Meanwhile, the preparation process of the polypropylene non-woven fabric soft master batch is simple, the existing non-woven fabric production process does not need to be adjusted when the polypropylene non-woven fabric soft master batch is used for soft non-woven fabric production, a filter screen is not blocked, the fabric softening finishing procedure can be reduced, and therefore the technological process is shortened.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polypropylene non-woven soft master batch material and a preparation method and application thereof. Background technique [0002] Polypropylene fibers have high breaking strength and elongation at break, and polypropylene textiles made from them have the advantages of fluffy, soft, and good strength. Therefore, in recent years, they have been used more and more in the manufacture of high-end sanitary napkins for women , baby diapers and adult incontinence products and other series of medical and hygiene products. The above products are in direct contact with the skin, and their softness will directly affect the user's comfort. Therefore, the softness of the product is an important property of non-woven materials for medical and hygiene use. However, polypropylene textiles will become rough to the touch after being processed in multiple steps during proce...
