Problems solved by technology

However, the yarn treated with emulsified wax feels hard and has poor hydrophilicity
Therefore, some softener emulsions and wax emulsions are compounded, such as patent publication CN102619090A, to make soft yarn smoothing agents; Textiles can obtain soft hand feeling after finishing, but the hydrophilicity decreases after finishing, which affects the subsequent treatment of yarn, and the addition of some softeners makes it easy to yellow after finishing
Patent Publication CN106012514A uses the emulsion prepared by emulsifying paraffin wax and softener together as a waxing agent after sizing to significantly reduce the number of warp breaks, but the emulsifier used is currently banned APEO emulsifier, which is poor in environmental protection
Patent publication CN105625026A uses composite wax to prepare yarn smoothing agent, which can effectively reduce the dynamic friction coefficient of yarn, but the problem of hydrophilicity decline after finishing is still unsolved

Abstract

The invention discloses a composite wax microemulsion composition, a preparation method and application thereof. The composite wax microemulsion composition contains: 8-28% by weight of high-melting point oxidized polyethylene wax, 4-14% by weight of low-melting point wax, 1-3% by weight of hyperbranched Gemini surfactant, 0.5-3% by weight hyperbranched softening agent, 3-13% by weight of emulsifier, 0.1-1% by weight of sodium hydroxide or potassium hydroxide, and 50-80% by weight of water, based on the total weight of the composite wax microemulsion. The composite wax microemulsion can be prepared by a one-step high-temperature emulsification method, and the process is simple. The prepared composite wax microemulsion has good centrifugation stability and dilution stability. Finishing it on textiles can significantly improve the smoothness of textiles, reduce the dynamic friction coefficient of yarns, improve the sewing performance and hydrophilicity of knitted fabrics, and reduce yellowing.

Description

Technical field [0001] The present invention relates to a high pro-hydraulic coating aid for textiles and a preparation method thereof, in particular to a composite wax microemulsion composition and a preparation method thereof. Background technique [0002] The yarn is in the process of the woven or winding, because the surface of the yarn is more hairpin, resulting in an increase in friction between the metal member, a cover, and steel, and under the tension, the yarn is extremely broken. It affects production efficiency and processing quality, so smoothing the yarn. [0003] The yarn smoothing agent currently used is a silicone oil slide agent, such as a smootry introduced in the Patent Publication CN107747224A, CN10480561B, which can reduce the friction factor of the yarn after the finishing, so that the yarn obtains a smooth hand, effectively reduces the break Rate, improve production efficiency and product quality. However, after the silicone oil smoothing agent has a poten...
