Problems solved by technology

In addition, cationic modifiers are easily hydrolyzed and lose their activity, which makes it difficult to reuse the additives. A large amount of lost additives remain in the waste liquid, which increases the difficulty of wastewater treatment.
[0004] Cotton cold pad-batch dyeing technology is relatively common in yarn and cloth dyeing, but it has not been applied in bulk fiber for a long time, the main reason is the lack of cold pad-batch dyeing equipment for bulk fiber

Embodiment 1

[0034] Select 100 kg of sawtooth cotton, and after opening, the cotton layer enters the rolling groove of the cold pad-batch dyeing machine for cationic modification treatment, wherein the modifier is 20 g / L; caustic soda is 10 g / L; non-ionic alkali-resistant penetrating agent is 10 g / Lift. The temperature of the treatment liquid is 30 degrees, the dipping time is 20 seconds, and the liquid carrying rate after rolling is controlled at 120%. After the treatment, the cotton layer was piled up in rolls for 15 hours, and then washed in a water washing machine until it was close to neutral to obtain cationic modified cotton. Select 100 kilograms of sawtooth cotton, first pre-treat the cotton by boiling (or scouring), and then apply anionic additives to impregnate and modify cotton loose fibers in the dyeing vat. The anionic additives in the treatment solution are 4 g / L; Yuanming powder 60 g / L; soda ash 8 g / L. Cotton fibers were soaked at 60°C for 30 minutes, and then washed with...

Embodiment 2

[0036] Select 100 kg of sawtooth cotton, and after opening, the cotton layer enters the rolling groove of the cold pad-batch dyeing machine for cationic modification treatment, in which the modifier is 30 g / L; caustic soda is 15 g / L; non-ionic alkali-resistant penetrating agent is 15 g / Lift. The temperature of the treatment liquid is 25 degrees, the dipping time is 25 seconds, and the liquid carrying rate after rolling is controlled at 130%. After the treatment, the cotton layer was piled up in rolls for 20 hours, and then washed in a water washing machine until it was close to neutral to obtain cationic modified cotton. Select 100 kilograms of sawtooth cotton, first pre-treat the cotton by boiling (or scouring), and then apply anionic additives to impregnate and modify cotton loose fibers in the dyeing vat. The anionic additives in the treatment solution are 6 grams per liter; Yuanming powder 80 g / L; soda ash 10 g / L. Cotton fibers were soaked at 70°C for 40 minutes, and th...

Embodiment 3

[0038] Select 100 kg of combed cotton mesh, after opening, the cotton layer enters the rolling groove of the cold pad-batch dyeing machine for cationic modification treatment, in which the modifier is 40 g / L; caustic soda is 25 g / L; non-ionic alkali-resistant penetrating agent 20 g / l. The temperature of the treatment liquid is 20 degrees, the dipping time is 30 seconds, and the liquid carrying rate after rolling is controlled at 180%. After the treatment, the cotton layer was piled up in rolls for 10 hours, and then washed in a water washing machine until it was close to neutral to obtain cationic modified cotton. Select 100 kg of combed cotton nets, first pre-treat the cotton (or scouring), and then apply anionic additives. The cotton loose fibers are impregnated and modified in the dyeing vat. The anionic additives in the treatment solution are 8 grams per liter; Yuan Ming Powder 80 g / L; Soda Ash 16 g / L. Cotton fibers were dipped at 80°C for 50 minutes, and then washed wit...

Abstract

The invention discloses a manufacture method for differentiated tingible cotton yarn. The method includes the following steps: cationic modified cotton and anionic modified cotton are prepared; the prepared cationic modified cotton and the prepared anionic modified cotton are blended into yarn; by weight, the blending proportion of the cationic modified cotton and the anionic modified cotton is 2%-98%: 98%-2%; and the spinning style is bunchy yarn or AB yarn or splash yarn or damask yarn. The differentiated tingible cotton yarn manufactured by using the method can have the effects of color-blend fancy yarn with strong contrast ratios, and needed hues are formed for one time; the differentiated tingible cotton yarn is excellent raw materials for processing top-grade underclothes, T-shirts, casual clothes and the like; and besides, the method is beneficial for reduction of factory inventory and shortening of product delivery time.

Description

technical field [0001] The invention relates to a method for making dyeable cotton yarn, more specifically, it relates to the process of cationic modification of cotton by cold pad-batch process of loose fibers and application of anionic additives to prepare anionically modified cotton differentiated dyeable cotton yarn Production Method. Background technique [0002] The cationic modification of cotton fiber can introduce a large amount of positive charges into the fiber, which greatly improves the affinity of the modified cotton fiber to anionic dyes, thereby improving the utilization rate of the dye, and making the cotton fiber dyeable under the conditions of no salt and no alkali. The modified cotton is blended with ordinary white cotton in a specific ratio to form white yarn, and then the yarn is dyed with anionic dyes to obtain the effect of mixed-color fancy yarn. Among them, the modified cotton component is normally colored, and the white cotton component is lighter...
