Abstract
The invention discloses a processing technology of waterproof yarn, which relates to the field of textile and mainly comprises the following steps: the method comprises the following steps: adding the deoiling agent and caustic soda into water, and heating to 90 ℃ for fully 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. Firstly, deoiling treatment is carried out on the yarn, so that the cleanness of the surface of the yarn can be ensured, the subsequent dyeing and waterproof treatment quality can be favorably improved, and the color fastness and the waterproof performance of the yarn are ensured.
Description
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-proof 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 yarns can be produced, when the yarns are stained with oil, waterproof agents and dyes are not easy to attach to the surfaces of the yarns or permeate into the yarns, so that the final quality of the waterproof yarns is influenced.

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 summary, 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-resistant effect of the yarn due to 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;
