Embodiment 1

[0030] This specific embodiment discloses a method and device for dyeing and finishing cotton knitted fabrics.

[0031] A method for dyeing and finishing cotton knitted fabrics, the method comprising the following steps:

[0032] Polishing enzyme treatment: immerse the cotton knitted fabric in the bio-polishing enzyme working solution to raise the temperature and keep it warm for a certain period of time, then take out the cotton knitted fabric for inactivation treatment. The components of the biological polishing enzyme working solution include buffer solution, refining penetrant and water. Preferably, the buffer solution is used in an amount of 1.3 g / L, and the refined penetrant is used in an amount of 3 g / L. Preferably, the composition and weight ratio of the refined penetrating agent are: 20% fatty alcohol polyoxyethylene ether, 18% alkyl polyoxyethylene ether, 15% secondary alcohol, and 47% water.

[0033] Dyeing and finishing: After the cotton knitted fabric is boiled a...

Embodiment 2

[0053] This specific embodiment discloses a method for dyeing and finishing cotton knitted fabrics. The difference from Example 1 is that in the polishing enzyme treatment step, the amount of buffer solution in the biological polishing enzyme working solution is 1.5g / L, the amount of scouring penetrant is 4g / L. The composition and weight proportion of the refining penetrant: 30% of fatty alcohol polyoxyethylene ether, 20% of alkyl polyoxyethylene ether, 20% of secondary alcohol, and 30% of water.

[0054] After the cotton knitted fabric is boiled and bleached in the dyeing and finishing process, the dosage of adding sodium bicarbonate to the working solution of bio-polishing enzyme is 80g / L, and the dosage of soda ash is 20g / L.

[0055] In the water bath device, the clamping device and the support device in Embodiment 1 are combined into Figure 5 The improved supporting device shown, the supporting device includes a sleeve 20, a motor 19, a push rod 8 and a fixing device; t...

Embodiment 3

[0058] This specific embodiment discloses a method for dyeing and finishing cotton knitted fabrics. The difference from Example 1 is that in the polishing enzyme treatment step, the amount of buffer solution in the biological polishing enzyme working solution is 1.4g / L, the amount of scouring penetrant is 4g / L. The composition and weight proportion of the refined penetrating agent: 25% of fatty alcohol polyoxyethylene ether, 18% of alkyl polyoxyethylene ether, 18% of secondary alcohol, and 39% of water.

[0059] After the cotton knitted fabric is boiled and bleached in the dyeing and finishing process, the dosage of adding sodium bicarbonate to the biopolishing enzyme working solution is 60 g / L, and the dosage of soda ash is 15 g / L.

[0060] The drape coefficient, weight reduction rate, bursting strength and color yield of the cotton knitted fabric dyed and finished by this specific embodiment all meet the standards, which are respectively 36.47% for the drape coefficient, 4....

Abstract

The invention provides a cotton knitted fabric dyeing and finishing method and a water bath apparatus. The method comprises: carrying out polishing enzyme inactivation treatment: dipping a cotton knitted fabric in bio-polishing enzyme working solution, firstly heating up, then carrying out heat preservation, and taking out the cotton knitted fabric to carry out inactivation treatment; carrying out dyeing and finishing treatment; after scouring and bleaching the cotton knitted fabric, adding a dye, anhydrous sodium sulphate and sodium carbonate into the bio-polishing enzyme working solution to carry out biological enzyme polishing and dyeing one-bath treatment. The apparatus used by the dyeing and finishing method comprises a pot body and an independent constant-temperature water bath unit in the pot; the constant-temperature water bath unit comprises a water bath tank, a clamping device, a supporting device, a heating device and a control panel. The cotton knitted fabric dyeing and finishing method and the water bath apparatus have the beneficial effects that by the method provided by the invention, a high-quality product can be produced; the apparatus used by the dyeing and finishing method provided by the invention can implement accurate temperature control and is applicable to various diameters of containers.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a cotton knitted fabric dyeing and finishing method and device. Background technique [0002] Dyeing and finishing refers to the process of chemically treating textile materials (fibers, yarns and fabrics). It is also commonly known as printing and dyeing in modern times. Together with spinning, weaving or knitting, dyeing and finishing form the whole process of textile production. Dyeing and finishing include pretreatment, dyeing, printing and finishing. The quality of dyeing and finishing has an important impact on the use value of textiles. Modern dyeing and finishing processes usually include polishing, bleaching, and dyeing. The traditional fabric polishing process in the prior art is boiling → draining → hot water → neutralization of peracid → washing → oxygen removal → dyeing → post-treatment. That is: first pre-treat the fabric, then remove the hyd...
