Problems solved by technology

Chinese patent CN101407952A discloses a kind of rope-shaped hemp stretching and thinning processing equipment with dispersed needle row. Needle row, through the multiple pricking and carding actions of the needle row, increases the dispersion density and the number of dispersions to refine the fibers. In essence, this is a mechanical treatment method that achieves fiber refinement by increasing the carding density. , this method can achieve the refinement of hemp fibers to a certain extent, but the high-intensity pricking and carding will lead to fiber damage and the decline of performance parameters such as strength
This method can reduce the damage to the fiber to a certain extent, but it does not fundamentally eliminate the cause of the damage

Embodiment 1

[0015] Example 1: Effect of jute process fiber treatment.

[0016] Treatment process: winding speed: 5 m / min; dispersing comb density: 30 teeth / cm; fiber liquid content rate after pressing water roller treatment: 10%; licker-in roller tooth density: 70 teeth / cm; in the stretching cabin : Steam temperature 110°C, relative humidity 90%. Stretch ratio: primary stretching: 1.4 stretching distance, the stretching distance is 1.2 times the average length of the hemp fiber bundle; secondary stretching: 1.8 stretching distance, the stretching distance is 1.7 times the average length of the hemp fiber bundle times. Referring to this process, the performance of the treated fiber was compared with that of the original fiber, and the results are shown in Table 1 below.

[0017] Table 1:

[0018]

[0019] It can be seen from the test that the stretched fiber has a large change in fineness, which has been reduced by nearly 30%. While the elongation at break of the fiber increases and...

Embodiment 2

[0020] Embodiment 2: Hemp craft fiber treatment effect.

[0021] Treatment process: winding speed: 5 m / min; density of dispersing comb teeth: 40 teeth / cm; liquid content rate of fibers after pressing water roller treatment: 15%; tooth density of licker-in roller: 70 teeth / cm; : Steam temperature: 120°C, relative humidity 90%; Stretch ratio: primary stretching: 1.2 stretching gauge, stretching gauge is 1.2 times the average length of hemp fiber bundles; secondary stretching: 1.6 stretching gauge , The tensile gauge is 1.7 times the average length of the hemp fiber bundle. Referring to this process, the properties of the treated fibers were compared with those of the original fibers, and the results are shown in Table 2 below.

[0022] Table 2:

[0023]

[0024]It can be seen from the test that the stretched fiber has a large change in fineness. While the elongation at break of the fiber increases and the initial modulus decreases, the fiber exhibits better toughness and e...

Embodiment 3

[0025] Embodiment 3: Treatment effect of flax fiber.

[0026] Treatment process: Winding speed: 5 m / min; Dispersing comb: Teeth density: 30 teeth / cm; After water roller treatment, fiber liquid content rate: 15%; Licker-in roller tooth density: 80 teeth / cm; In the stretching cabin : steam temperature 130 ℃, relative humidity 95%; stretching ratio: primary stretching: 1.5 stretching gauge, stretching gauge is 1.3 times the average length of hemp fiber bundles; secondary stretching: 1.7 stretching gauge, The tensile gauge is 1.8 times the average length of the hemp fiber bundle. Referring to this process, the properties of the treated fibers were compared with those of the original fibers, and the results are shown in Table 3 below.

Abstract

The invention discloses a fibrilia stretching and refining processor comprising a soaking tank and a stretching cabin, wherein multiple paths of upper and lower yarn guide rollers and a set of water pressing roller are arranged in the soaking tank, and conditioning fluid is contained in the soaking tank; fibrilia to be processed passes through a dispersing comb and then enters the water pressing roller through the upper and lower yarn guide rollers; and the stretching cabin is a sealed box body filled with steam; and the fibrilia guided out from the water pressing roller enters an upper guide roller, a lower guide roller and three sets of front, middle and rear stretching rollers in the box body through a licker-in, and then is guided out. The fibrilia stretching and refining processor can be used for effectively stretching and refining the fibrilia, causes less strength loss of the fibrilia, and improves the using ratio of the fibrilia in fabrics for clothes.

Description

technical field [0001] The invention relates to a fiber processing device, in particular to a hemp fiber stretching and thinning processing device. Background technique [0002] my country is the country with the richest flax resources and the largest output in the world, among which the output of ramie accounts for more than 90% of the world's total output, the output of flax ranks second in the world, and there are more than 100 species of flax plants. Hemp fiber is a green ecological textile fiber, which has the advantages of good moisture absorption, heat dissipation, coolness, and crispness. It is one of the important textile raw materials today, and has huge market potential at home and abroad. Hemp fibers are widely used in home textiles, decoration, ropes, clothing, hats, footwear and other fields. However, because hemp fibers are relatively short and hard, except for ramie, all other hemp fibers are made of technical fibers. The processing process is to retting an...
