Embodiment 1

[0031] To achieve the above object, the present invention provides the following technical solutions:

[0032] An ultra-soft two-component waterproof and breathable non-woven fabric, including two layers of PE spunbond non-woven fabric layers with soft and breathable functions on the outer layer and modified PP melt-blown non-woven fabric layers on the inner layer .

[0033] Further, the modification treatment process of the PP nonwoven layer comprises the following steps:

[0034] Ⅰ. Immerse the inner PP melt-blown layer as a non-woven fabric product in the mixed solution; raise the temperature of the mixed solution to 50°C, and ultrasonically disperse at this temperature for 20 minutes; after the ultrasonic dispersion is uniform, store it for later use;

[0035]Ⅱ. Mix the pretreated mixed solution, PP non-woven fabric, modifier with a mass of 30% of PP non-woven fabric, dicyclopentenyl acrylate DCPA with a mass of 5% of PP non-woven fabric, and modified The initiator of 0....

Abstract

The invention relates to the technical field of textiles, in particular to a super-soft bi-component waterproof and breathable non-woven fabric and a production process thereof. The super-soft bi-component waterproof and breathable non-woven fabric is composed of an upper PE spun-bonded non-woven fabric layer, a lower PE spun-bonded non-woven fabric layer and an inner PP melt-blown non-woven fabric layer; an outer PE non-woven fabric layer serves as a super-soft breathable layer; and the inner PP non-woven fabric layer serves as a waterproof and anti-ultraviolet sterilization layer. The production process comprises the following steps that a PP melt-blown non-woven fabric is subjected to modification treatment, so that dodecyl trimethyl ammonium chloride and 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid are effectively fastened on a PP non-woven fabric. Then a PE spun-bonded non-woven fabric bottom layer, a modified PP melt-blown non-woven fabric inner layer and a PE spun-bonded non-woven fabric surface layer are subjected to hot rolling compounding. The prepared product not only has super-soft touch feeling and excellent waterproof and breathable functions, but also has excellent ultraviolet resistance, aging resistance and slow-release sterilization performance, and the quality of the non-woven fabric is improved while the service life of the non-woven fabric product is prolonged.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a supersoft two-component waterproof and breathable nonwoven fabric and a production process thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, non-woven fabrics, are fabrics that do not require yarns or filaments to be interwoven or woven, but short fibers or filaments are oriented or randomly arranged to form a web structure, and then Reinforced by mechanical reinforcement, thermal bonding or chemical bonding. The technological process of non-woven fabric production can generally be divided into four processes: fiber / raw material selection, web formation, fiber reinforcement (forming), and finishing. [0003] Nonwoven technology is a material processing technology that originates from textiles but surpasses textiles. It combines the four major flexible material processing technologies of textile, papermaking, leather and plastic, and f...
