Description

Technical Field

[0001] The invention belongs to the technical field of feather yarn dyeing, in particular to a feather yarn dyeing process. Background Art

[0002] Feather yarn is a product with high economic benefits and good development prospects. During the production process, feather yarn needs to go through processes such as blending, mixing, combing, drawing, coarse yarn processing, fine yarn processing, and dyeing.

[0003] With regard to the dyeing of feather yarn, the existing dyeing process usually adopts the immersion method. During the operation, it is difficult to control the temperature and time of feather yarn dyeing, resulting in uneven coloring of the feather yarn after dyeing, and even different degrees of coloring of the same batch of feather yarn, which reduces the dyeing quality of the feather yarn and increases the dyeing cost of the feather yarn. Summary of the invention

[0004] To achieve the above object, the present invention provides the following technical solution: a feather yarn dyeing process, comprising the following steps:

[0005] S1. Feather yarn material: by observing and comparing the surface of the feather yarn, the feather yarn with fluff on the surface is screened out, and the feather yarn without fluff on the surface is screened out;

[0006] S2. Dyeing agent material: According to the material and color requirements of the feather yarn, select the dye that meets the requirements. Both reactive dyes and acid dyes can be used for dyeing feather yarn;

[0007] S3, dyeing treatment: installing the feather yarn roller shaft at one end of the dyeing tank, installing the feather yarn take-up roller at the other end of the dyeing tank, rotating the installation roller shaft inside the dyeing tank, and the feather yarn is finally collected on the take-up roller through the rotating installation roller shaft inside the dyeing tank;

[0008] S4. Subsequent treatment: After the dye solidifies, the feather yarn on the winding roller is cleaned and dried to remove impurities on the surface of the feather yarn.

[0009] Preferably, when the feather yarn in S3 passes through the dyeing tank, the dye in the dyeing tank needs to be slowly stirred by a stirring device to avoid stratification of the dye.

[0010] Preferably, when the feather yarn in S3 passes through the dyeing tank, the dyeing temperature and time need to be controlled. The dyeing effect is represented by a value E, the temperature is represented by T, and the time is represented by t. The temperature and time have the following relationship: E=KT a t b , where K is a constant, a and b are positive numbers less than 1, reflecting the degree of influence of temperature and time on dyeing effect.

[0011] Preferably, when the feather yarn in S3 passes through the dyeing tank, the temperature change causes the structure of the feather yarn fiber to change. Within a specified time and within a certain temperature range, the fiber will expand, thereby increasing the pores inside the fiber, which is beneficial for the entry of dye molecules.

[0012] Preferably, when the feather yarn in S3 passes through the dyeing tank, for dyes requiring chemical reactions, the time is extended within the specified temperature to make the reaction more complete, which helps to improve the bonding force between the dye and the fiber and enhance the dyeing fastness.

[0013] Preferably, the feather yarn in S1 needs to be processed in batches, and the following relationship applies to the selection of feather yarn batches:

[0014] I = w1S + w2C + w3L;

[0015] where w 1 、w 2 、w 3 are the weight coefficients of yarn strength, color uniformity and hairiness length,

[0016] S represents yarn strength, C represents color uniformity, L represents hairiness length, w represents 1 、w 2 、w 3 They are all determined based on actual production needs and importance.

[0017] Preferably, the stirring blades of the stirring device adopt a spiral stirring form, and the stirring device is evenly distributed on the top of the dyeing tank. The rotation speed of the stirring device is controlled at 20r / min-100r / min, and the appropriate rotation speed needs to be selected according to the specific situation.

[0018] Preferably, the cleaning of the feather yarn in S4 is carried out by flushing with flowing water, the temperature of the feather yarn needs to be controlled, and the feather yarn needs to be evenly placed during drying so that it is evenly heated.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the work, the coloring of feather yarn is controlled by controlling the relationship between the temperature and time of the dyeing pool, which is convenient for controlling the relationship between the temperature and time of feather yarn dyeing, ensuring the uniform coloring of feather yarn after dyeing, ensuring that the coloring degree of feather yarn in the same batch is similar, improving the dyeing quality of feather yarn, and reducing the dyeing cost of feather yarn.

[0021] 2. In the work, by selecting the materials for feather yarn, defective products can be largely removed, which can improve the yield rate of feather yarn, and different batches of feather yarn can be divided and selected to improve the quality of feather yarn.
