Description

Antioxidant antistatic spinning oil
Technical Field
The invention belongs to the technical field of synthetic fiber additives, and particularly relates to antioxidant antistatic spinning oil.
Background
Synthetic fibers do not have special adhesion on the surface of natural fibers, so that chemical fiber oiling agents are indispensable to be used in the fiber spinning process. The friction characteristic of the fiber can be adjusted by using the oil agent, the static accumulation is prevented or eliminated, the cohesive force among tows is controlled, the fiber is endowed with good convergence, smoothness and fiber separation, and the smooth performance of chemical fiber spinning is ensured. The oil agent on the surface of the fiber is firstly contacted with production equipment, and the configuration of the oil agent has obvious influence on the production cost, the production efficiency and the product quality under the conditions determined by raw materials and production process equipment. The prior oiling agent for chemical fibers mainly comprises a smoothing agent, a bundling agent, an antistatic agent, an emulsifier, a balance regulator and the like; however, due to the difference of the components, the phenomena of broken filaments, broken ends and the like are easy to occur in the spinning process, so that the winding forming is poor, the high-quality product rate is low, the corrosion phenomenon is serious, and the requirements of the spinning process are difficult to adapt.
In the production and post-processing of chemical fiber, in order to have better spinnability, the static electricity of the protofilament must be eliminated, the friction coefficient must be adjusted, the fiber must be smooth and soft, and the fiber must pass through the processes of spinning, drafting, winding, twisting, spooling, weaving and the like, so that proper spinning oil must be added. The components of the commonly used chemical fiber oil agent can be divided into two categories: the first main group comprises components of a smoothing agent, an antistatic agent and an emulsifier, and the second main group comprises auxiliary components of a wetting agent, a softening agent, a cohesive agent, an antioxidant, a fiber separating agent, a penetrating agent, a pH regulator, a viscosity modifier, a stabilizer, an antifoaming agent, an antimicrobial agent, a preservative, a balance regulator and the like. The conventional oil agent consists of more than 90 percent of main components and less than 10 percent of auxiliary components, and is used for adjusting the friction performance of chemical fibers together, preventing or eliminating static accumulation and endowing the fibers with the performances of smoothness, bundling, static resistance, softness and the like.
The silk oil agent can adjust the friction coefficient between fibers and between metals, reduce static electricity generated by friction, enable the fibers to have good bundling property, smoothness and fiber separation property, and meet the requirements of relevant procedures of fiber post-processing. In general, a chinlon spinning oil agent mainly comprises a wetting agent, a bundling agent, a smoothing agent, an emulsifier, an antistatic agent and the like. The common filament oiling agent has the main functions of smoothly winding oiled fibers, forming a filament tube well, reducing broken filaments and broken ends in a drawing process and ensuring normal drawing. Therefore, the oil agent is required to have good antistatic properties, moderate wettability, fiber cohesion, smoothness, high temperature resistance, and low volatility. In recent years, with the high-speed spinning of the nylon industry, the development of fine denier, functionalization and greenization of fibers, higher performance requirements are put forward on the performance of nylon spinning oil.
However, most of the existing nylon spinning oil agents in the current market have the following defects, including: some cotton spinning oil agents have poor heat resistance, oxidation resistance and oxidation resistance, and are easy to yellow nylon fibers, so that great loss is caused; the emulsifier in some nylon spinning oil contains APEO (ammonium polyoxyethylene ether), and APEO is an environmental hormone substance, which causes difficulty in product export of downstream printing and dyeing enterprises and causes environmental pollution and ecological hazard; in addition, some nylon spinning oil agents in the current market have poor emulsibility, so that the oil agents on the yarns are not easy to clean, and further, the subsequent dyeing is influenced. Particularly, the antistatic property of the cotton spinning oil agent needs to be further improved, phosphate ester is generally adopted as an antistatic agent in the market, which can only ensure that the oil agent has good antistatic property under high humidity, but under the condition of low humidity, the antistatic effect is greatly reduced, so that the phenomena of winding and end breakage caused by poor antistatic property often occur in dry seasons or northern areas.
