Technical Field

The invention relates to the field of textiles, in particular to a processing technology of waterproof yarn.

Background

The yarn is a product processed into certain fineness by various spinning fibers and is used for gauze, rope making, thread making, knitting, embroidery and the like. Furthermore, the yarn, which is usually white when produced from a yarn machine, can also be dyed as desired for use in clothing, bedding or other decorative articles.

For outdoor sports enthusiasts working in offices in the weekdays, the enthusiasts often go to parks or forests to participate in certain outdoor sports only at the morning and at the night. However, in both of these two periods, the outdoor air temperature is generally low, and especially in winter, frost and dew are easy to appear in the morning and at night. At this time, if the outdoor sports enthusiasts keep warm by knitting clothes or hats, because the water contact angles of the surfaces of the common yarns are less than 90 degrees, water drops are easy to adhere to the surfaces of knitwear made of the yarns, the knitwear products are easy to become damp in the process of sports, lose the warm-keeping effect, and are easy to catch a cold after a long time. For this reason, some companies have also introduced yarns with good water-repellent properties.

However, the yarns are often contaminated with oil stains during production and transportation, and generally, the oil stains are often ignored during the waterproofing process of enterprises and are directly produced. Although waterproof yarn can be produced, when the yarn is stained with oil, the waterproof agent and dye are not easy to adhere to the surface of the yarn or permeate into the yarn, so that the final quality of the waterproof yarn is affected.

Disclosure of Invention

The invention aims to provide a processing technology of waterproof yarn, which carries out pretreatment of deoiling on the yarn and ensures the efficiency and quality of subsequent dyeing and waterproofing of the yarn.

The above object of the present invention is achieved by the following technical solutions: a processing technology of waterproof yarn mainly comprises the following steps:

the method comprises the following steps: adding the deoiling agent and caustic soda into water, and uniformly mixing to obtain deoiling liquid;

step two: soaking and deoiling the yarns in deoiling liquid;

step three: neutralizing and cleaning the deoiled yarn by using an acetic acid solution, and then washing with water;

step four: dyeing the washed yarn, and then cleaning;

step five: soaking the cleaned yarn in waterproof liquid for waterproof treatment;

step six: and cleaning the waterproof yarn, shading and drying in the shade, and drying to obtain the finished waterproof yarn.

Through adopting above-mentioned technical scheme, the deoiling liquid that utilizes deoiling agent and caustic soda and water to make carries out the deoiling to the yarn and handles, can guarantee the cleanness on yarn surface like this to can be favorable to improving follow-up dyeing and water repellent's quality, guarantee the colour fastness and the waterproof performance of yarn.

Meanwhile, in the sixth step, the yarn is cleaned and then shaded, so that the dyeing agent and the waterproof agent tend to be stable on the surface of the yarn, and the quality of the final yarn is ensured.

Preferably, the oil removing agent mainly comprises, by mass, 5-9 parts of carbamide, 3-7 parts of an anionic surfactant, 25-31 parts of water, 15-19 parts of ethanol, 2-4 parts of fatty alcohol-polyoxyethylene ether, 8-12 parts of polyaspartic acid and 7-13 parts of starch.

Through adopting above-mentioned technical scheme, fatty alcohol polyoxyethylene ether helps anionic surfactant and sodium hydroxide to permeate to inside the yarn to can help the oil stain to take place saponification reaction under the effect of sodium hydroxide on the one hand, anionic surfactant can help the oil stain and the product after the oil stain saponification to dissolve in aqueous on the other hand, thereby be convenient for detach the oil stain on the yarn.

In addition, the polyaspartic acid has the performance of scale inhibition, so that the scale formation of calcium and magnesium ions in water on the surface of the yarn can be reduced, and the subsequent yarn dyeing and waterproof treatment are influenced. And the carbamide can protect the yarn, so that the possibility of damage to the yarn in the oil removing process is reduced.

Preferably, the anionic surfactant is sodium dodecylbenzenesulfonate.

By adopting the technical scheme, the sodium dodecyl benzene sulfonate has good degreasing capability and relatively stable performance. In addition, some of the carbonamide and sodium dodecylbenzenesulfonate may remain on the surface of the yarn after the processing is completed. Later, if the textile made of the yarn is bitten by insects, the carbamide and the sodium dodecyl benzene sulfonate enter the insects, at the moment, the carbamide destroys the chitin layer in the insects, and the sodium dodecyl benzene sulfonate dissolves the wax layer on the insects through the destroyed chitin layer, and forms an airtight film at the air holes on the insects, so that the insects die by suffocation, thereby playing a role in killing insects.

Preferably, the starch is subjected to oxidative modification treatment by an oxidizing agent.

By adopting the technical scheme, the oxidized starch can be compounded with the polyaspartic acid, so that the oxidized starch can promote scale deposition crystals generated by calcium and magnesium ions to gradually form obvious sheet-shaped and layered structures and form certain pits. Therefore, the irregular crystals can easily make the scale layer soft and can be easily washed away by water, thereby reducing the possibility of scale on the surface of the yarn and being suitable for being used in areas with more hard water in the north.

Preferably, the waterproof agent mainly comprises, by mass, 13-15 parts of cyanuric chloride, 20-30 parts of acrylic resin, 15-17 parts of ethylene glycol, 10-15 parts of higher aliphatic alcohol acrylate, 2-4 parts of polyether silicone oil, 7-13 parts of diethanolamide and 70-80 parts of water.

By adopting the technical scheme, on one hand, the cyanuric chloride can increase the surface tension of the yarn, water is not easy to stay on the surface of the yarn, and on the other hand, the acrylic resin and the polyether silicone oil can form a water conveying layer on the yarn, so that the possibility that the textile made of the yarn is wetted is reduced.

Preferably, the cyanuric chloride is modified by linking 1, 6-hexamethylenediamine to a secondary palmityl amine.

By adopting the technical scheme, the secondary palmityl amine is grafted to the cyanuric chloride, so that the cyanuric chloride has a water-repellent functional group, and the waterproof capability of the yarn can be effectively improved when the modified cyanuric chloride is attached to the surface of the yarn or permeates into the yarn.

Preferably, in the fourth step, the dyed yarn is alternately cleaned by three times of clear water and two times of cleaning solution containing the KST cleaning agent.

By adopting the technical scheme, the dye which is not stably attached to the yarn can be removed completely, so that the components in the waterproof liquid can be more easily attached to the surface of the yarn, and the waterproof performance of the yarn is improved.

Preferably, in the fourth step, the time for washing with clean water for three times is 5min, 3min and 3min respectively, and the time for washing with the cleaning solution for two times is 15min respectively.

Through adopting above-mentioned technical scheme, can keep the cleaning performance of yarn on the one hand, on the other hand also can reduce the use amount of clear water and cleaner to manufacturing cost has been reduced.

Preferably, in the fifth step, the yarn is soaked into the waterproof liquid at normal temperature, then the waterproof liquid is gradually heated to 40 ℃ and is kept warm for 10min, then the waterproof liquid is continuously heated to 50 ℃ and is kept warm for 20min, and finally the waterproof liquid is continuously heated to 60 ℃ and is kept warm for 20 min.

By adopting the technical scheme, the temperature is firstly increased to 40 ℃, so that the components in the waterproof liquid can be smoothly dispersed in the yarns, and the problem of uneven distribution of the waterproof liquid groups is avoided. Then the temperature is raised to 50 ℃ and 60 ℃ so that the waterproof components in the waterproof liquid can be uniformly combined with the surface of the yarn, and the waterproof quality of the yarn is ensured.

In conclusion, the beneficial technical effects of the invention are as follows:

1. firstly, the yarn is subjected to oil removal treatment, so that the later dye and waterproof components are favorably ensured to be attached to the surface of the yarn;

2. the carbamide, the sodium dodecyl benzene sulfonate and the fatty alcohol-polyoxyethylene ether are selected as main components of the oil removing agent, so that the oil removing agent has a good oil removing effect, can play a certain role in ensuring the yarn, and can improve the insect resistance of the yarn by the synergistic effect of the residual carbamide carbonate and the sodium dodecyl benzene sulfonate;

3. the cyanuric chloride in the waterproof liquid is grafted with the palmityl secondary amine, so that the tension on the surface of the yarn can be reduced, and a water-repellent functional group can be introduced, thereby improving the waterproof effect of the yarn;

4. the starch can be compounded with the polyaspartic acid after being oxidized and modified, and the possibility that calcium and magnesium ions in water form scale on the surface of the yarn can be reduced, so that the oil removing efficiency of the oil removing liquid is improved.
