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 compound wax microemulsion composition, and a preparation method and an application thereof. The compound wax microemulsion composition comprises the following components inpercent by weight: 8-28wt% of high melting point oxidized polyethlene wax, 4-14wt% of low melting point wax, 1-3wt% of a hyperbranched Gemini surfactant, 0.5-3wt% of a hyperbranched softener, 3-13wt%of an emulsifier, 0.1-1wt% of sodium hydroxide or potassium hydroxide and 50-80wt% of water based on the total weight of the compound wax microemulsion. The compound wax microemulsion can be preparedby a one-step high-temperature emulsification method which is simple in process. The prepared compound wax microemulsion is good in centrifugal stability and diluting stability. By trimming the microemulsion to a textile, the smooth performance of the textile can be improved obviously, the coefficient of kinetic friction of yarns can be reduced, the sewing performance and hydrophilia of a knittedfabric are improved, and yellowing is reduced.

Description

technical field [0001] The invention relates to a highly hydrophilic smooth finishing auxiliary agent for textiles and its preparation method and application, in particular to a composite wax microemulsion composition and its preparation method and application. Background technique [0002] During the weaving or winding process of the yarn, because the surface of the yarn has a lot of hairiness, the friction between it and the yarn guide, heald eye, reed and other parts increases, and the yarn is easily broken under the action of tension. It affects the production efficiency and processing quality, so the yarn should be smoothed. [0003] Currently used yarn smoothing agents are mostly silicone oil smoothing agents, such as the smoothing agents introduced in patent publications CN107747224A and CN10480561B, which can reduce the friction factor of yarn after finishing, so that the yarn can obtain a smooth feel and effectively reduce broken ends rate, improve production effic...
