Embodiment 1

[0037] The embodiment of the invention provides colored knitted fleece and O-shaped cylinder dyeing process.

[0038] A kind of O-type cylinder dyeing process of colored knitted fleece, the specific operation steps are as follows:

[0039] The knitted flannelette which is processed by the reduction process and processed by blending polyester yarn with a share ratio of 1:1 and modified polyester yarn is transported to the O-shaped cylinder, and the mass ratio is 1:1. It is a dyeing agent mixed with a neutral dyeing agent and a cationic dyeing agent, and the dosage of the dyeing agent is 0.5g / L. After the dyeing agent is added, it is evenly mixed with the liquid in the O-type cylinder, and then the temperature of the O-type cylinder is increased to raise the temperature of the dye solution to 125 degrees Celsius, and the temperature is kept for 25 minutes, so that part of the dye solution in the O-type cylinder is converted into a gaseous state. The medium dyeing liquid is spra...

Embodiment 2

[0044] The embodiment of the invention provides colored knitted fleece and O-shaped cylinder dyeing process.

[0045] A kind of O-type cylinder dyeing process of colored knitted fleece, the specific operation steps are as follows:

[0046]The knitted flannelette to be raised after the reduction process and processed by the blending of polyester yarn with a share ratio of 1:2 and modified polyester yarn is transported to the O-type cylinder, and the mass ratio of 1:2 is added. The dyeing agent is a mixture of neutral dyeing agent and cationic dyeing agent, and the dosage of dyeing agent is 1g / L. After the dyeing agent is added, it is evenly mixed with the liquid in the O-type cylinder, and then the temperature of the O-type cylinder is increased to raise the temperature of the dye solution to 150 degrees Celsius, and the temperature is kept for 35 minutes, so that part of the dye solution in the O-type cylinder is converted into a gaseous state. The medium dyeing liquid is spr...

Embodiment 3

[0051] The embodiment of the invention provides colored knitted fleece and O-shaped cylinder dyeing process.

[0052] A kind of O-type cylinder dyeing process of colored knitted fleece, the specific operation steps are as follows:

[0053] The knitted flannelette which has been processed by the reduction process and processed by blending polyester yarn with a share number ratio of 1:1.5 and modified polyester yarn is transported to the O-shaped cylinder, and the mass ratio is 1:1.5. It is a dyeing agent mixed with a neutral dyeing agent and a cationic dyeing agent, and the dosage of the dyeing agent is 0.6g / L. After the dyeing agent is added, it is evenly mixed with the liquid in the O-type tank, and then the temperature of the O-type tank is increased to raise the temperature of the dye solution to 130 degrees Celsius, and the temperature is kept for 30 minutes, so that part of the dye solution in the O-type tank is converted into a gaseous state. The medium dyeing liquid is...

Abstract

The invention relates to the technical field of textile and provides a dyeing process for colored knitted fleeced cloth in an O-type vat. The dyeing process comprises the following steps of: placing knitted cloth to be fleeced into the O-type vat for dyeing, wherein the concentration of a dyeing agent in the O-type vat is 0.5-1g / L; rising the temperature of dyeing liquor in the O-type vat to 125-150 DEG C to lead partial dyeing liquor in the O-shaped vat to be transformed into a gas state, and spraying the dyeing liquor in the O-type vat to the knitted cloth to be fleeced in the form of gas-liquid mixing so as to start dyeing; after dyeing, carrying out cleaning and dewatering. The dyeing process is good in dyeing effect, and the colored knitted fleeced cloth prepared by the dyeing processis high in bulkiness and good in elasticity. The invention also provides the colored knitted fleeced cloth which are obtained by adopting the dyeing process for colored knitted fleeced cloth in the O-type vat to dye and then fleecing. The colored knitted fleeced cloth is high in bulkiness, good in elasticity and good in color. The invention also provides clothes with the manufacturing fabric including the colored knitted fleeced cloth. The clothes are beautiful in appearance and high in comfort level.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a colored knitted fleece, an O-shaped cylinder dyeing process and clothing. Background technique [0002] Knitted fleece, also known as pk two-color fleece fabric, is mainly a sportswear fabric with the characteristics of softness and breathability. Generally, it needs to go through cylinder matching, rewinding, cutting, shrinking, dyeing, fleece, and finished product setting. Waiting for the process. In order to improve the comfort level of the clothes made of fleece, the quality of existing fleece still needs to be improved. [0003] In view of this, the present application is proposed. Contents of the invention [0004] The invention provides an O-shaped cylinder dyeing process for colored knitted fleece, aiming at improving the general problems of bulkiness and elasticity of knitted fleece dyed by the existing dyeing process. [0005] The invention also provides a color...
