Embodiment 1

[0116] according to figure 1As shown in the process diagram, the 37g / m merino wool sliver 1 made of an average fiber diameter of 18.7 microns and an average fiber length of 77.2mm (the longest fiber length is 150mm) is twisted to 16 turns with the flyer twister 2 The wool slivers / m were sent to the pretreatment tank 5 at a speed of 1.3m / min, and plasticized and swelled for 30 minutes at 40°C in the treatment solution of the following composition.

[0117] Sodium bisulfite 30g / l

[0118] Monoethanolamine 2g / l

[0119] Caustic soda about 10g / l (adjust the pH of the treatment solution to 8.0)

[0120] Then, send this sliver to the reduction tank 17 that has added the solution with the same composition as the pretreatment tank liquid, and carry out plasticization and swelling under the conditions of 80°C and 30 seconds, and then use steam 18 to carry out 95°C, 70 seconds of steam treatment. Simultaneously, the superficial speed of roller group 12,13 is accelerated ...

Embodiment 2

[0140] A 37 g / m wool sliver with an average fiber diameter of 27.0 microns and an average fiber length of 70.0 mm is applied with a flyer twister 2 to twist at 16 revolutions / m. Except for the following processing conditions, the others are the same as in Example 1. Processing conditions are processed.

[0141] [Conditions different from Example 1]

[0142] i) Composition, treatment temperature and time of the plasticizing and swelling pretreatment tank 5:

[0143] Sodium bicarbonate 1.5g / l

[0144] Sodium carbonate 0.15g / l

[0145] Immersion conditions 60°C, 10 minutes

[0146] ii) Stretch ratio: 1.7 times (actual stretch ratio: 1.25 times)

[0147] iii) Instead of passing through the reduction treatment tank 17 and omitting the oxidation treatment with hydrogen peroxide, it is replaced with hot water at 80°C (treatment tanks 24, 29, 34).

[0148] iv) Treat tank 39 with acetic acid instead of formic acid, and perform neutralization treatment at pH 4.5.

Abstract

The present invention provides a fine-long animal hair fibre and its production method which can fix its stretched state, do not damage crimp recovery, reduce fibre diameter, increase fibre length and raise fibre glossiness. Its production includes the following steps: (a) for animal hair stripe, implementing twisting procedure; (b) soaking the twisted animal hair stripe in alkaline aqueous solution and making the animal hair stripe undergo the process of swelling and plasticity treatment; (c) reduction procedure for cutting disulfide bond in the swelling plasticity fibre; (d) drawing procedure for actually drawing the swelling plasticity fibre to 1.20-1.60 times; (e) using oxidant to oxidate the drawn animal hair fibre; and (f). using acid to make neutralization.

Description

technical field [0001] The present invention relates to elongated animal hair fibers temporarily or permanently fixed in a stretched and elongated state, a method for producing the same, and a spun yarn obtained by mixing the elongated animal hair fibers. Background technique [0002] Conventionally, attempts have been made to perform stretching in order to bulk up animal hair fibers, reduce weight, improve heat retention, and produce finer count spun yarns. In the Japanese Patent Publication No. 44-15136, it is disclosed that the wool top is twisted according to a single, double, or multiple twisting method, and a 30% stretch is given in water at 70°C containing a penetrating agent and a nonionic active agent. Stretching and setting treatment is carried out at about 50°C for about 1 hour, cooled in water, untwisted, and air-dried. Its purpose is to stretch the temporary set, and to perform relaxation treatment in the subsequent process to break the temporary set and reprod...
