Problems solved by technology

Generally, waterproof finishing is carried out on polyurethane, polyester, cotton / polyester, wool and silk fabrics. Conventional waterproof finishing agents are generally aluminum sulfate, fatty acid chromium complexes, ammonium compounds or threads of long-chain aliphatic hydrocarbons. Type polysiloxane, which forms a coating on the fabric by padding first and then baking. This method is complex, long-processed, and consumes a lot of energy. It is only semi-durable or not durable. After finishing, the fabric or yarn The thread feels hard

specific Embodiment 1

[0039] A kind of processing method of 60S / 2 waterproof mercerized cotton yarn:

[0040] 1. singeing

[0041] When singeing on the yarn singeing machine, the singeing temperature is 950°C, and the running speed of the 60S / 2 cotton yarn at the burner is 875 rpm to burn off the hairiness on the surface of the cotton yarn. The burner temperature is required to be uniform and the singeing is clean basically the same degree;

[0042] 2. Shaking yarn

[0043] On the yarn reeling machine, the package yarn after singeing is swayed into a skein shape, and the skein weight is 250g / skein;

[0044] 3. Mercerized

[0045] In the mercerizing machine, by controlling the mercerizing alkali temperature, time, tension, and alkali concentration, the yarn is evenly mercerized. The alkali concentration in the treatment solution is: 30 degrees Baume, the treatment solution temperature: 18°C, and the treatment time: 6 minutes. Tension: Stretch 3%, Washing temperature: 70°C;

[0046] 4. Boil ...

specific Embodiment 2

[0068] A kind of processing method of 70S / 2 waterproof mercerized cotton yarn:

[0069] 1. Singeing

[0070] When singeing on the yarn singeing machine, the singeing temperature is 1000°C, and the running speed of the 70S / 2 cotton yarn at the burner is 900 rpm to burn off the hairiness on the cotton yarn surface. It is required that the temperature of the burner is uniform, and the cleanliness of the singeing is basically the same;

[0071] 2. Shaking yarn

[0072] On the spinning machine, the singed cheese is shaken into a skein shape, and the skein weight is 500g / skein;

[0073] 3. Mercerized

[0074] In the mercerizing machine, by controlling the mercerizing alkali temperature, time, tension, and alkali concentration, the yarn is evenly mercerized. The alkali concentration in the treatment solution is: 28 degrees Baume, the treatment solution temperature: 20°C, and the treatment time: 6 minutes 30 seconds, tension: stretch 6%, washing temperature: 70°C;

[0075] 4. B...

specific Embodiment 3

[0097] A kind of processing method of 80S / 2 waterproof mercerized cotton yarn:

[0098] 1. Singeing

[0099] When singeing on the yarn singeing machine, the singeing temperature is 1050°C, and the running speed of the 80S / 2 cotton yarn at the burner is 1000 rpm to burn off the hairiness on the cotton yarn surface. It is required that the temperature of the burner is uniform, and the cleanliness of the singeing is basically the same;

[0100] 2. Shaking yarn

[0101] On the spinning machine, the singed cheese is swayed into a skein shape, and the skein weight is 1000g / skein;

[0102] 3. Mercerized

[0103] In the mercerizing machine, by controlling the mercerizing alkali temperature, time, tension, and alkali concentration, the uniform mercerizing of the yarn is ensured. The alkali concentration in the treatment solution is: 25 degrees Baume, the treatment solution temperature: 22°C, and the treatment time: 7 minutes. Tension: Stretch 1%, Washing temperature: 70°C;

Abstract

The invention relates to a production method of nanometer waterproof mercerized yarns, which can obtain mercerized cotton yarns with permanent waterproof effect and soft hand feeling. In addition, the invention has the advantages of processing time saving, energy source saving and processing process simplification. The invention has the technical scheme that the method comprises the processes of singeing, yarn reeling, mercerizing, kier bleaching, dyeing, soap washing, hot water washing, cold water washing, color fixation, softening, water squeezing, baking and rewinding. The invention is characterized in that the nanometer organic fluorine waterproof finishing agent process is carried out after the color fixation process, and the softening process and the subsequent processes thereof arecarried out after the nanometer organic fluorine waterproof finishing agent process. The nanometer organic fluorine waterproof finishing agent process comprises the following concrete steps: placing the yarns into liquid in a yarn bundling dyeing machine to be processed; and then, using hot water for washing, wherein nanometer organic fluorine waterproof finishing agents are added into the liquidin the yarn bundling dyeing machine.

Description

technical field [0001] The invention relates to the field of production technology of mercerized cotton yarn, in particular to a production method of nanometer waterproof mercerized yarn. Background technique [0002] With the improvement of living standards, the requirements for clothing fabrics are getting higher and higher, especially for the functional requirements of fabrics. Waterproof and oil-proof functional fabrics are becoming more and more popular among consumers. Generally, waterproof finishing is carried out on polyurethane, polyester, cotton / polyester, wool and silk fabrics. Conventional waterproof finishing agents are generally aluminum sulfate, fatty acid chromium complexes, ammonium compounds or threads of long-chain aliphatic hydrocarbons. Type polysiloxane, which forms a coating on the fabric by padding first and then baking. This method is complex, long-processed, and consumes a lot of energy. It is only semi-durable or not durable. After finishing, the ...
