Spinning oil used for easily-dyed terylene BCF (bromochlorodifluoromethane) carpet yarn

Abstract

The invention discloses spinning oil used for easily-dyed terylene BCF (bromochlorodifluoromethane) carpet yarn, which belongs to the technical field of oil used for processing synthetic fibre. The spinning oil is characterized in that the spinning oil used for easily-dyed terylene BCF carpet is composed of the following components according to parts by weight: 50-60 parts of smoothing agent, 20-25 parts of emulsifying agent, 7-15 parts of bundle collecting agent and 2-5 parts of antistatic agent. According to the spinning oil, the terylene molecular chain characteristic and the terylene BCF spinning process requirement can be satisfied. The spinning oil has good stability, the oil attaching amount on the fiber can be lowered by the oil emulsion, cost is lowered, and pollution is reduced; little oil is volatilized in short time, more oil is volatilized in long time, few cokes are formed, and therefore the cokes are easy to clean; cohesive force among terylene fibers can be improved, and fiber strength is improved; oil viscosity becomes stable along with the variation of the concentration; in the spinning process, tension is stable, and broken ends are less. The waste silk rate can be reduced to 8% from the original 15%, and the terylene BCF carpet yarn quality and the production efficiency are obviously improved.

Description

technical field [0001] The invention relates to a spinning oil used for easily dyed polyester BCF carpet yarn, and belongs to the technical field of oil for processing synthetic fibers. Background technique [0002] At present, with the rapid development of my country's real estate, tourist hotels, aviation, railway, highway and other transportation, as well as the automobile industry, the use of various chemical fiber carpets continues to increase, and the application prospects of chemical fiber BCF are broad. The main raw materials of BCF carpet yarn are nylon, polypropylene and a small amount of polyester. In recent years, due to the good heat resistance and light resistance of polyester, the advent of cationic modified polyester, and its strong price advantage, polyester has become an important substitute for traditional carpet materials. However, polyester molecular chains are tightly packed, with high crystallinity and orientation, low polarity, lack of hydrophilicity...

AI Technical Summary

Problems solved by technology

[0003] (1) The heat resistance of the oil agent is poor. During the high-temperature and high-speed spinning process, most of the oil agent volatilizes and decomposes, the strength of the oil film decreases, and the smoothness becomes poor, resulting in wool and broken ends;

[0004] (2) The viscosity and thickness of the oil agent is poor, and the viscosity of the phase inversion point of the oil agent is relatively high, which causes severe fluctuations in tension and seriously affects the quality of the product;

[0005] (3) In the high-speed spinning process, 90 or 144 monofilaments form a polyester BCF carpet yarn under certain cohesion, stretching and deformation processes. The wettability of the oil agent is poor, and it cannot be quickly and evenly attached to the fiber surface. The cohesion performance between fibers is poor, the fiber strength is reduced, and then the draft and deformation are affected, and the waste silk rate is increased.
