Problems solved by technology

[0004] Traditionally, there is a technology of cutting the iridescent film through a slitting machine to prepare decorative lace. The technology is only to cut the film into narrow strips of corresponding width, and has not carried out corresponding in-depth research and modification. The narrow strips currently prepared have many Fiber properties unsuitable for textile garment comfort

Embodiment 1

[0022] like figure 1 As shown, the preparation method of the multi-slit nanofiber assembly yarn in this embodiment includes the following steps: (1) package an ultra-thin PET / PA hot-melt resin with a diameter of 60 cm, a width of 100 mm, and a thickness of 30 μm The combined iridescent film 1 is unwound. During the unwinding process, a layer of titanium oxide nanotube water emulsion (containing 1% solid content) with a thickness of 5um is coated on the surface of the iridescent film by the slit coating head 2, and then passed through the guide roller 3. Use the ultrasonic blade module film slitting machine 4 to cut the iridescent film into 200 continuous non-dyed multicolored flat filaments with a width of 0.5mm at a speed of 80m / s; The fluid nozzle sprays air for twisting, the twist is 0 twist / 10 cm, and the heating device 5 heats the corresponding twisting point at 210 degrees to soften the continuous non-dyed multicolored flat yarn, and under the synergy of the winding devi...

Embodiment 2

[0025] The preparation method of the multi-slit nanofiber aggregate yarn in this embodiment includes the following steps: (1) A rainbow of ultra-thin PA / PET hot-melt resins with a package diameter of 60 cm, a width of 100 mm, and a thickness of 50 μm are combined. The film slitting machine with a mechanical rotary circular blade module cuts the iridescent film into 100 continuous non-dyed multicolored flat filaments with a width of 1.0mm at a speed of 100m / s; The fluid nozzle sprays air for twisting, with a twist of 100 twists / 10cm. At the same time, the heating device heats the corresponding twisting point at 180 degrees to soften the continuous non-dyed multicolored flat yarn. Under the synergy of the winding device, The continuous non-dyed multicolored flat yarn is stretched twice its length, and when the continuous non-dyed multicolored flat yarn is stretched and thinned to no color, it becomes an elliptical wire with a spiral twist, and the 200-layer film in the rainbow di...

Embodiment 3

[0028]The preparation method of the multi-slit nanofiber aggregate yarn in this embodiment includes the following steps: (1) A combination of ultra-thin PE / PET hot-melt resin with a package diameter of 60 cm, a width of 100 mm, and a thickness of 50 μm. The film is cut into 1000 continuous non-dyed multicolored flat filaments with a width of 0.1mm by a straight blade module film slitting machine at a speed of 200m / s; Twist, the twist is 1000 twists / 10 cm, and the heating device heats the corresponding twisting point at 210 degrees to soften the continuous non-dyed multicolored flat yarn, and under the synergy of the winding device, the continuous non-dyed multicolored flat The silk is stretched 5 times its length, and when the continuous non-dyed multicolored flat silk is stretched and thinned to no color, it becomes an oval silk with a spiral twist, and the thickness of the 200-layer film in the rainbow diaphragm is stretched The wavelength of the visible light (400-700nm) is...

Abstract

The invention discloses a preparation method of a multi-slit nanofiber assembly yarn, which comprises the following steps: (1) cutting the iridescent film into a continuous non-dyed multicolored flat yarn with a film slitting machine; (2) making the step ( 1) The obtained continuous non-dyed multicolored flat yarns are divided into groups of 1-10 pieces, sprayed with air through the fluid nozzle for twisting, while spraying air for twisting, heat the twisting point with a heating device to make the continuous non-dyed multicolored flat yarns The silk is softened, then wound and stretched by a winding device to obtain a five-color yarn; (3) the five-color yarn obtained in step (2) is output to the winding device to make a twisted five-color yarn bobbin. The preparation method of the invention has simple operation, mild conditions, and low cost of raw materials. The winding and stretching of the invention increases the thinning of the flat filaments, improves the mutual cohesion fastness, and improves the overall strength of the multi-slit nanofiber assembly yarn.

Description

technical field [0001] The invention belongs to the technical field of fiber and yarn material preparation, and in particular relates to a preparation method of a multi-slit nanofiber aggregate yarn, which belongs to a dry spinning method. Background technique [0002] Iridescent film is a film material developed abroad in the 1980s based on the interference principle of multilayer films. It is completely different from the color plastic film that is commonly used in color printing and dyeing. A kind of thermoplastic transparent resin (the difference in refractive index is 0.03), through multi-layer compound co-extrusion, it is made into a film with more than 30 layers, uniform and parallel in the thickness direction, with a thickness of 0.015-0.05mm and a rainbow effect film, which varies with the viewing angle. Colors vary. Its colorful color effect is based on the principle of optical refraction, interference, and reflection. When the reflection band is in the wavelength...
