Description

Lubricant products for spining in textile industry

The present invention relates to an emulsion composition for anti-foaming spinning, and has excellent lubrication, heat resistance, antistatic properties and emulsification safety in spinning spinning of fiber materials composed of various types, and improves spinning performance and uses materials that are not harmful to the human body. It is to enable improvement of gender and working environment.

In general, anti-fog emulsions should be composed of appropriate combinations of chemical ingredients with various conditions such as smoothness, binding, wettability, emulsification stability and detergency. Is on the verge of diversification.

For example, as various raw materials such as wool, hemp, silk, and cotton rayon are complicatedly input, the anti-spinning emulsion of the past does not satisfy the requirements of the above-described emulsion.

In this regard, the emulsion composition invented this time is developed and added additives to intensively complement the smoothness, focusing and antistatic properties in order to meet the processing conditions of various raw materials to obtain a higher yield and improve productivity compared to the past products I could make it.

The present invention is to improve the performance required for a woolen spinning emulsion due to on-site production equipment or working conditions that are developed day by day during the spinning process of each type of natural fibers or synthetic fibers to solve the above-mentioned disadvantages Based on the combination of specific ingredients at the point of time to maximize the properties of the chemicals and to meet these requirements, it is completed and can be supplied at an economical price through proper blending. The present invention provides an emulsion composition having excellent smoothness, wettability and detergency.

Petroleum-based mineral oil used in the present invention is an additive for imparting lubricity and smoothness in the spinning spinning process of various fiber raw materials, 20 kSt (centistock) is mainly used at 40 ° C, and emulsification stability to impart excellent emulsification stability and lubricity. 8cSt with excellent lubricity but poor lubricity and 31cSt with good lubricity but lack of emulsification stability and detergency were mixed to complement each other's strengths and weaknesses. The amount was 47 to 83% by weight depending on the processing process and raw materials.

Alkylphenolethoxylates (4 to 10 moles) are additives used to improve emulsification, dispersion, wetting and detergency in the woolen spinning process, and the number of moles of EO (ETHYLENE OXIDE) added to the additives is the detergency of the fiber material. 4 to 10 moles are assumed to be excellent, and 4 to 9.5 wt% is suitable depending on the processing process and raw materials.

Lauryl alcohol ethoxylate (3 to 5 moles) is used to impart excellent emulsification stability and detergency to the processed material and also aims to minimize side effects that may occur when contacting the skin. The number of moles of EO added to the additive is suitably 3 to 5 moles in order to obtain stable emulsification, and 0 to 4% by weight depending on the processing and raw materials.

Sulfated castor oil was used to impart lubricity and smoothness in the spinning process and to obtain excellent emulsion stability. 3 to 10 wt% is suitable.

Oleic acid was used to impart excellent lubricity and smoothness to the processed raw materials and 0 to 4% by weight is suitable.

Polyethylene glycol monoalkyl esters were used to impart lubricity and smoothness to the processed raw materials and were formulated to exhibit excellent properties depending on the hydrocarbon composition of the applied fatty acids (lauric acid, stearic acid). Polyethyleneglycol monolaurate with a molecular weight of 300 to 600 and polyethyleneglycol monostearate with a molecular weight of 300 to 600 have been used to impart lubricity and smoothness to the processed raw materials. Formulated to exert excellent properties, 5 to 9% by weight, 3 to 6% by weight, respectively.

Lauryl betaine exhibits positive surfactant properties, giving excellent emulsification stability, wettability and cleansing properties to processed raw materials. Especially, it is applied for health and safety of workers by minimizing irritation to skin, and 0 to 3% by weight is suitable.

Diethylene glycol is applied to improve the wettability and lubricity of the raw materials, as a stabilizer of the emulsion, and to improve the fluidity of the product stock during the winter season, 2 to 5% by weight is suitable.

Potassium hydroxide is preferably 0 to 1.5% by weight as a raw material for adjusting the pH of the emulsion to 6.5 to 7.5.

Ethanolamine is used as a corrosion inhibitor of the pH of the emulsion and processing equipment, 0 to 1% by weight is suitable.

Ion-exchanged water is used for emulsification and viscosity control of stock solutions.
