The shaped fiber is a fiber with a special cross section, which is spun through a spinneret orifice with a certain geometrical shape (non-circular shape), and is also called as a 'shaped cross section fiber', and the shaped fiber is relative to a circular fiber and is extruded through the spinneret orifice with the special geometrical shape, so that the cross section of the fiber presents a certain geometrical shape.
Chinese patent application No. 202010704535.2 discloses a preparation method of a profiled cross-section fiber non-woven fabric with a unidirectional moisture-conducting function, which comprises the following steps: step 1: the preparation of the special-shaped section polyester non-woven fabric is carried out by a dry method non-woven fabric production process flow, and the special-shaped section polyester non-woven fabric is obtained by compounding fiber webs with the weight of 300-100 g/m2 and the needling density of 350 needling/cm 2 and 200 needling/cm 2 respectively; step 2: co-depositing dopamine/nano particles/polyethyleneimine (DA/SiC/PEI) to prepare a 50mmol/L Tris solution, and then adding hydrochloric acid (HCl) with the concentration of 0.1mol/L to adjust the pH value to 8.5 to obtain a solution I; weighing DA in a certain mass, fully dissolving the solution I, and uniformly stirring to prepare a solution II with the concentration of 2 mg/mL; adding silicon carbide particles (SiC, 0.5-0.7 um) with a certain mass, and fully stirring for 15min to obtain a silicon carbide solution with the concentration of 2%, namely a solution (c); dissolving a certain mass of PEI into the solution (c), wherein the concentration of PEI is 1mg/mL, and magnetically stirring for 30min to obtain a DA/SiC/PEI solution; finally, uniformly spraying DA/SiC/PEI solution on the side, with low needling density, of the non-woven fabric (5 cm 5), obtained in the step 1, after depositing for 2 hours, arranging the deposited non-woven fabric in a forced air drying oven, and standing for 3 hours at 50 ℃ for later use; and step 3: hydrophobic functionalization treatment: weighing 100.0mL of absolute ethyl alcohol, placing the absolute ethyl alcohol in a 250.0mL round-bottom flask, slowly adding 15.0mL of ammonia water, heating the mixture to 50 ℃ in a water bath kettle, continuously stirring the mixture for 30min, slowly adding 6.0mL of ethyl orthosilicate solution into the solution within 1h, and continuously stirring the solution at constant temperature for 1h to prepare silicon dioxide sol; under the condition of room temperature, 1.0mL of perfluorodecyl triethoxysilane, 2.0mL of hexadecyl trimethoxysilane and 2.0mL of dodecyl trimethoxysilane are measured and added into the silicon dioxide sol dropwise, and the mixture is stirred at constant temperature for 30min continuously to obtain a hydrophobizing agent; and finally, uniformly spraying the hydrophobing agent with different volumes on one side of the non-woven fabric with the single-side deposited obtained in the step 2, and airing under natural conditions to obtain the non-woven fabric with the special-shaped cross section and the unidirectional moisture-conducting function. The patent uses special-shaped polyester fiber as a raw material to prepare non-woven fabric, improves the non-woven fabric by adopting substances such as dopamine and the like, and then carries out hydrophobic treatment to obtain the non-woven fabric with the one-way moisture-conducting function, which has stronger adhesion and higher mechanical property, but the non-woven fabric has hard hand feeling and poorer longitudinal diffusion property, and is not suitable for being applied to disposable sanitary products such as paper diapers and the like.
