[0023] The present invention has the following beneficial effects:

[0024] The textile composite wax provided by the present invention comprises microcrystalline wax, polyethylene wax and silicone oil. The synergistic effect among the microcrystalline wax, polyethylene wax and silicone oil is beneficial to improving the mechanical properties, abrasion resistance, pilling resistance, softness, smoothness, wrinkle resistance, antistatic property, air permeability, stain resistance and waterproof grade of the yarn. DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be described clearly and completely below. If the specific conditions are not specified in the embodiments, they are carried out according to conventional conditions or conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be purchased commercially.

[0026] An embodiment of the present invention provides a textile composite wax, comprising microcrystalline wax, polyethylene wax and silicone oil, wherein the mass ratio of the microcrystalline wax, polyethylene wax and silicone oil is 0.7-1.1:0.5-1:0.5-1.2.

[0027] The textile composite wax provided by the present invention comprises microcrystalline wax, polyethylene wax and silicone oil. The synergistic effect among the microcrystalline wax, polyethylene wax and silicone oil is beneficial to improving the mechanical properties, abrasion resistance, pilling resistance, softness, smoothness, wrinkle resistance, antistatic property, air permeability, stain resistance and waterproof grade of the yarn.

[0028] The embodiment of the present invention also provides a method for waxing a yarn, comprising: immersing the yarn to be treated in an impregnation liquid for impregnation treatment;

[0029] The impregnated yarn is taken out from the impregnating liquid and dehydrated and dried to obtain the treated yarn;

[0030] Wherein, the impregnation liquid includes water and the textile composite wax described in the above embodiment.

[0031] In the yarn waxing method provided in the embodiment of the present invention, waxing is carried out by dipping, which is beneficial for full contact between the yarn and the textile composite wax and for exerting the effect of the textile composite wax.

[0032] In an optional embodiment, the mass fraction of the textile composite wax in the impregnation solution is 0.3wt%-0.7wt%, specifically 0.3wt%, 0.4wt%, 0.5wt%, 0.6wt%, 0.7wt% or any value between 0.3wt% and 0.7wt%.

[0033] Reasonable selection of the mass fraction of textile composite wax in the impregnation solution is conducive to the uniform and sufficient attachment of textile composite wax to the yarn and penetration into the yarn, and is more conducive to the improvement of the effect of textile composite wax. If the mass fraction of textile composite wax is too low, then under the same conditions, the amount of textile composite wax attached to the yarn surface or penetrated into the yarn will be reduced, and the effect of improving the yarn performance will not be significant; if the mass fraction of textile composite wax is too high, it will be unfavorable for the uniform distribution of textile composite wax in the yarn, which will also lead to unsatisfactory improvement of yarn performance.

[0034] In an optional embodiment, the mass ratio of the textile composite wax in the impregnating liquid to the mass of the yarn to be treated is 2%-3.5%, specifically 2%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3.0%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5% or any value between 2% and 3.5%.

[0035] The ratio of the mass of the textile composite wax in the impregnation liquid to the mass of the yarn to be treated is closely related to the content of the textile composite wax in the yarn, which in turn affects the improvement of the yarn performance. If the mass of the textile composite wax in the impregnation liquid is too low relative to the mass of the yarn, the content of the textile composite wax in the yarn obtained will also be too low, resulting in limited performance improvement; if the mass of the textile composite wax in the impregnation liquid is too high, it will not only lead to a waste of the textile composite wax, but also deteriorate the yarn performance.

[0036] In an optional embodiment, the mass ratio of microcrystalline wax, polyethylene wax and silicone oil in the textile composite wax is 0.7-1.1:0.5-1:0.8-1.2.

[0037] Specifically, the mass ratio of the microcrystalline wax in the textile composite wax in the impregnating liquid to the mass ratio of the yarn to be treated can be 0.7%, 0.8%, 0.9%, 1.0%, 1.1% or any value between 0.7% and 1.1%; the mass ratio of the polyethylene wax in the textile composite wax in the impregnating liquid to the mass ratio of the yarn to be treated can be 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0% or any value between 0.5% and 1.0%; the mass ratio of the silicone oil in the textile composite wax in the impregnating liquid to the mass ratio of the yarn to be treated can be 0.8%, 0.9%, 1.0%, 1.1%, 1.2% or any value between 0.8% and 1.2%.

[0038] When the amount of the textile composite wax is within this range, the yarn performance can be improved while reducing the amount of the textile composite wax.

[0039] In an optional embodiment, the textile composite wax further comprises paraffin wax, and the mass ratio of paraffin wax, microcrystalline wax, polyethylene wax and silicone oil in the textile composite wax is 3-4:1:0.5-1:0.5-1.

[0040] In order to reduce the cost, paraffin wax with low cost can be added to the textile composite wax. After adding paraffin wax, the amount of each component in the textile composite wax can be adjusted. Specifically, the mass ratio of paraffin wax in the textile composite wax in the impregnation liquid to the mass ratio of the yarn to be treated can be 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2% or any value between 1.5% and 2%; the mass ratio of polyethylene wax in the textile composite wax in the impregnation liquid to the mass ratio of the yarn to be treated can be 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, 0.5% or any value between 0.25% and 0.5%; the mass ratio of silicone oil in the textile composite wax in the impregnation liquid to the mass ratio of the yarn to be treated can be 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, 0.5% or any value between 0.25% and 0.5%.

[0041] In an optional embodiment, the immersion treatment temperature is 60°C-70°C, specifically 60°C, 62°C, 64°C, 66°C, 68°C, 70°C or any value between 60°C and 70°C; the time is 10min-12min, specifically 10min, 11min, 12min or any value between 10min-12min.

[0042] Reasonable setting of the impregnation temperature is conducive to ensuring that the textile composite wax is evenly dispersed in the impregnation liquid, and sufficient impregnation time is conducive to the uniform attachment and penetration of the textile composite wax into the yarn. In some embodiments, in order to make the yarn evenly waxed, the impregnation liquid soaked with the yarn can be turned and stirred while keeping the impregnation liquid immersed in the yarn.

[0043] In an optional embodiment, the impregnation liquid also includes an emulsifier, and the mass ratio of the emulsifier to the textile composite wax is 1.5%-2%, specifically 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2% or any value between 1.5% and 2%; the emulsifier is at least one of the OP series emulsifiers such as nonylphenol polyoxyethylene ether and alkyl glycoside.

[0044] The addition of the emulsifier is beneficial to the uniform dispersion of the textile composite wax in the impregnation solution, and is also beneficial to the penetration of the textile composite wax into the interior of the yarn, and is beneficial to the uniform distribution of the textile composite wax in the yarn.

[0045] In an optional embodiment, the drying temperature is 65°C-80°C, specifically 65°C, 70°C, 75°C, 80°C or any value between 65°C and 80°C.

[0046] In an optional embodiment, the material of the yarn is at least one of cotton, polyester and nylon;

[0047] And / or, the average molecular weight of the silicone oil is 4500-5500;

[0048] And / or, the average molecular weight of the microcrystalline wax is 800-1200;

[0049] And / or, the average molecular weight of the polyethylene wax is 2500-3500.

[0050] An embodiment of the present invention further provides a yarn obtained by being treated with the yarn waxing method described in any one of the aforementioned embodiments.
