Embodiment 1

[0029] Such as figure 1 As shown, it is a structural schematic diagram of a differential mechanical stirring device. The differential mechanical stirring device includes at least one stirring rod arranged in the container 11, and the described stirring rod includes a first transmission rod 2 and a The second transmission rod 6 in the first transmission rod 2, one end of the first transmission rod 2 is connected with the stirring comb 1, and the other end is connected with the transmission gear 3, and the transmission gear 3 is connected with the stirring comb stepper motor 4, and the second transmission rod 6 One end is connected with the lower stirring comb 5, the other end is connected with the lower stirring comb stepping motor 7, and the upper stirring comb 1 and the comb pieces of the lower stirring comb 5 are opposite. The container 13 is arranged on the sample stage 8, and the sample stage 8 is connected to the stepping motor 9 through a rotating shaft. The size, s...

Embodiment 2

[0031] Cut the washed and dried wool into 5mm long fiber segments, immerse in 98% formic acid and boil for 10 minutes, then undergo ultrasonic vibration with a power of 400W for 10 minutes and then ultrasonic vibration with a power of 200W for 20 minutes to complete descaling. Immerse the descaled wool in 98% formic acid at a solid-to-liquid ratio of 1g / 100ml, and perform ultrasonic vibration at a frequency of 20kHz and a power of 200W in a constant temperature water bath at 20°C for 5h. Afterwards, undecomposed wool fibers were removed by filtration with a 100-mesh screen, and the filtrate was passed through a 400-mesh screen to obtain a spindle-shaped protofibril with a diameter of 4.8 μm and a length of 120.0 μm.

[0032] Using the differential mechanical stirring device described in Example 1, a formic acid solution 10 with a temperature of 20°C and a volume concentration of 85% was placed in a container 13, and a part of the spindle-shaped raw wool with a diameter of 4.8 μ...

Embodiment 3

[0034] The washed and dried cashmere was cut into 5 mm long fiber segments, which were consistent with the preparation method and steps of the wool protofibril in Example 1. Spindle-shaped fibrils with a diameter of 3.0 μm and a length of 105.5 μm were obtained.

[0035]Using the differential mechanical stirring device described in Example 1, place a formic acid solution 10 with a temperature of 40°C and a volume concentration of 70% in a container 13, and take a part of the cashmere spindle with a diameter of 3.0 μm and a length of 105.5 μm The fibrillar body is put into the formic acid solution 10, and the ultrasonic oscillation frequency is set to 20kHz, and the power is 150W; the rotation direction of the upper stirring comb 1 and the lower stirring comb 2 is opposite, the stirring frequency is 2Hz, and the rotation angle is 30°, using 6 There are two stirring rods, the number of comb pieces of the upper stirring comb 1 and the lower stirring comb 2 is 4, the rotational sp...

Abstract

The invention provides a preparing device for keratin original fibers with forked head ends and a method. The preparation method for keratin original fibers is characterized in that specific steps include adding formic acid solution into a container of a differential type mechanical stirring device, feeding spindle-shaped keratin original fibers with the diameter ranging from 3mum to 5mum and thelength ranging from 80mum to 120mum into the formic acid solution, and obtaining the keratin original fibers with the forked head ends by means of centrifugation or filtration under joint effects of ultrasonic oscillation and differential type mechanical stirring. As the preparation method adopts differential stirring, the force and the probability of forking the head ends of the spindle-shaped animal keratin original fibers are increased, yield of the forked original fibers is improved effectively, and the average number of the forked head ends and superficial area can be directly increased by 20% at least.

Description

technical field [0001] The invention relates to the preparation technology of the protofibril body of the head-end bifurcation, especially adopts the preparation method of the differential mechanical agitation of the comb, and applies the obtained protofibril body from natural hair to the keratin homogeneous composite film. Background technique [0002] Shaped fibers can be divided into two types, one is fibers with a shaped overall cross-section, such as triangular fibers, I-shaped fibers, etc. The second is fibers with irregular cross-sections at the head end (or in the length direction), such as bone (dumbbell)-shaped fibers, bamboo-shaped fibers, bifurcated fibers, etc. [0003] After retrieval, the related patents of the first type of fibers with special-shaped overall cross-section and their preparation methods include: the invention patent "three-lobe special-shaped spinneret" with application number 201020200715.9 describes that during the melt spinning of polymers, ...
