Embodiment 1

[0021] Spinning kenaf / cotton (30 / 70) blended yarn.

[0022] 1 Kenaf soft treatment

[0023] (1) Water retting. Weigh 30 g of kenaf fiber and soak in water for 12 hours.

[0024] (2) Alkaline oxygen bath treatment. Configure alkaline oxygen bath solution, bath ratio is 1:20 (alkali oxygen solution 600g), total alkali concentration is 4% (24g), first add alkali concentration 0.8% (4.8g), hydrogen peroxide concentration 1% (mass fraction 30%) 20g of hydrogen peroxide), additives anhydrous sodium sulfite, magnesium sulfate, and sodium polyphosphate are all 3% of the dry weight of the fiber (0.9g each). Weigh 0.9g each of anhydrous sodium sulfite, magnesium sulfate, and sodium polyphosphate, 4.8g sodium hydroxide, add 523.3g water, then add 20g 30% hydrogen peroxide, and then retort the semi-dried kenaf fiber Put it into the prepared alkaline oxygen bath solution, when the temperature is raised to 95℃, add the remaining sodium hydroxide (19.2g) and water (30g) solution, keep it for 2h...

Embodiment 2

[0038] Spinning kenaf / cotton (60 / 40) blended yarn.

[0039] 1 Kenaf soft treatment

[0040] (1) Water retting. Weigh 50g of kenaf fiber and soak in water for 24h.

[0041] (2) Alkaline oxygen bath treatment. Weigh a certain amount of semi-dried kenaf fiber after retting, configure alkali-oxygen bath solution, bath ratio is 1:20 (solution 1000g), total alkali concentration is 3% (30g), first add alkali concentration 0.8% (8g) The concentration of hydrogen peroxide is 2% (67g of 30% hydrogen peroxide), and the additives anhydrous sodium sulfite, magnesium sulfate, and sodium polyphosphate are all 2% of the dry fiber weight (1g each). Weigh 1g each of anhydrous sodium sulfite, magnesium sulfate, and sodium polyphosphate, 8g sodium hydroxide, 860g water, and 67g 30% hydrogen peroxide to make an alkaline oxygen bath solution, then add the semi-dried kenaf after retting. The fiber is heated to 95°C at 1°C / min in a constant temperature water bath, and then a solution of remaining sodium...

Abstract

The invention discloses a manufacturing method of kenaf and cotton blended yarns. According to the manufacturing method, the blended yarns is prepared from the following raw materials in percentage by weight: 30 to 60 percent of kenaf with the fiber length of 30 to 50 mm and 70 to 40 percent of cotton fibers with the fiber length of 30 to 38 mm. The technical process comprises the following steps: performing hermitical treatment on the kenaf through water retting, alkali-oxygen bath treatment, softening and a carding agent, then mixing the kenaf with the cotton fibers, and performing opening, carding, drawing, roving and spinning to obtain the kenaf and cotton blended yarns. The carding is carried out by using a roller type carding machine, and other operations are carried out by using cotton spinning equipment.

Description

Technical field [0001] The invention belongs to the textile field, and specifically relates to the development of a kenaf and cotton blended yarn and its spinning technical method. Background technique [0002] Kenaf, also known as kenaf and kenaf, is an annual herbaceous bast fiber crop. It is widely planted because of its high yield, resistance to salt and drought, and low requirements for the growth environment. It is one of the important raw materials for hemp spinning. my country is one of the main producers of kenaf. The further development and utilization of kenaf will not only provide abundant high-performance raw materials for textile, papermaking, animal husbandry, composite materials and other fields, but will also promote the further development of the domestic kenaf industry. Because of the high lignin content of the kenaf fiber, the rough and hard fibers and poor spinnability, most of them are currently used to process low value-added products such as sacks, linen c...
