Embodiment 1

[0092] a. Presoaking solution treatment: wash the wool with clean water, remove impurities, remove the floating skin, and comb it into wool tops; measure the length of the tied wool tops and install them on two chucks; immerse in the stretching pretreatment solution for 20 minutes to fully moisten the wool top fibers wet.

[0093] b. Twisting stretching: Add a certain twist to the wool top and feed it into the false twisting stretching device. The twist of the added false twisting is 1.67 twist / 10cm; the roller gauge is 10mm; the stretching rate is 30%; the stretching speed It is 20mm / min.

[0094] c. Heating and wetting: use steam to heat and wet the twisted top to 80-90°C and start stretching.

[0095] d. One-time setting: Put the stretched wool top into the first-time setting solution and soak for 3 minutes.

[0096] e. Rinse: Rinse with water for 2 minutes after taking it out.

[0097] f. Secondary setting: After washing, squeeze out the water, then put it into the seco...

[0112] a. Presoaking solution treatment: wash the wool with clean water, remove impurities, remove the floating skin, and comb it into wool tops; measure the length of the tied wool tops and install them on two chucks; immerse in the stretching pretreatment solution for 10 minutes to fully moisten the fibers of the wool tops wet;

[0113] b. Twist stretching: add a certain twist to the wool top, and feed it into the false twist stretching device. The twist of the added false twist is 2.0 twist / 10cm, the roller gauge is 8mm, the stretch rate is 35%, and the stretch speed 15mm / min;

[0114] c. Heating and wetting: use steam to heat and wet the twisted top to 80-90°C and start stretching;

[0115] d. One-time setting: put the stretched wool top into the first-time setting solution and soak for 4 minutes;

[0116] e. Rinse: Rinse with water for 2 minutes after taking it out;

Embodiment 3

[0132] a. Pre-soaking treatment: wash the wool with clean water, remove impurities, remove the floating skin, and comb it into wool tops; measure the length of the tied wool tops and install them on two chucks; immerse in the stretching pretreatment solution for 30 minutes to fully moisten the wool top fibers wet;

[0133] b. Twisting and stretching: Add a certain twist to the wool top and feed it into the false twist stretching device. The twist of the added false twist is 1.2 twist / 10cm, the roller gauge is 12mm, the stretch rate is 25%, and the stretch speed 25mm / min;

[0134] c. Heating and wetting: use steam to heat and wet the twisted top to 80-90°C and start stretching;

[0135] d. One-time setting: put the stretched wool top into the first-time setting solution and soak for 2 minutes;

[0136] e. Rinse: Rinse with water for 2 minutes after taking it out;

[0137] f. Secondary setting: After washing, squeeze out the water, then put it into the secondary setting solut...

Abstract

The present invention relates to a wool fibre modification method, belonging to the field of natural fibre technology. Said method includes the following steps: preimpregnation treatment of wool fibre, twisting and drawing, heating and moistening, first setting, rinsing, secondary setting and drying so as to obtain high-count fine wool.

Description

technical field [0001] The invention relates to the field of natural fibers, in particular to a method for modifying wool fibers. Background technique [0002] With people's growing demand for lighter and more luxurious clothing, it has become a general trend of international textiles to develop wool products that are comfortable, environmentally friendly and easy to care for. Since weaving high-count light and thin fabrics requires high-count fine wool, the use of stretching technology to increase the wool fiber count has become a research hotspot in the world today. Wool stretching and thinning method is a non-polluting processing technology that rapidly thins wool by artificial means. On the premise of not destroying the fiber scales, the fiber is pretreated, stretched and shaped, and the intermolecular structure of the fiber is changed to make the whole The fibers become thinner and elongated, which can be used to produce light and thin fabrics with soft luster, silk-li...
