Abstract

The invention provides a super flexible S/S stereoscopic two-component spunbond non-woven material and a preparing method thereof. The non-woven material is prepared from polypropylene a, polypropylene b, a softening agent and color master batch. Non-woven fabric made of the super flexible S/S stereoscopic two-component spunbond non-woven material has the advantages of being good in hydrophilicity, high in softness, compact in texture and small in gram weight, and fitting to skin, the surface density of the material is 30-80 g/m<2>, the longitudinal strength is 80-240 N/5cm, the longitudinal elongation at break is 90%-120%, the longitudinal bending rigidity is 200-800 cN. cm, the longitudinal bending length is 2-4 cm, the transverse strength is 50-180 N/5cm, the transverse longitudinal elongation at break is 60%-100%, the transverse bending rigidity is 160-480 cN. cm, the transverse bending length is 3-7 cm, and the stereoscopic thickness of the material is 0.5-2 mm.

Description

technical field [0001] The invention belongs to the field of nonwoven fabrics, and in particular relates to a supersoft S / S three-dimensional two-component spun-bonded nonwoven material and a preparation method thereof. Background technique [0002] Non-woven fabric (non-woven fabric) is a kind of fabric formed without spinning and weaving. It just orients or randomly arranges short textile fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical bonding. Reinforced by other methods. To put it simply: it is not interwoven and knit together by yarns one by one, but the fibers are directly bonded together through physical methods, so when you get the sticky scale in your clothes , you will find that it is impossible to extract the thread ends one by one. Nonwovens have broken through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, ...
