Description

Emulsion composition for spinning

The present invention relates to an emulsion composition for woolen spinning, and more particularly, to impart excellent lubricity before spinning yarns, lamb's yarn, Mary's yarn, woolen yarn and synthetic fibers, etc. Oil-proofing spinning oil for lubricating oil to improve the soft effect in the rubbing process by preventing the fiber cutting to improve the yield and to provide the proper antistatic property and the proper focusing between the fiber and the fiber (F / F) To a composition.

Generally, anti-emulsion emulsions should have the conditions such as lubricity, smoothness, antistatic property, concentrating property and detergency. Since nonionic or anionic surfactants often have the above conditions in combination, they may be mixed and used properly. It is very important to.

However, the various chemical components constituting the conventional anti-emulsion emulsion generally have properties that are opposite to each other (see JAOCS, Vol 65, No. 01 (October 1988)), that is, if the lubricity is excellent Cohesiveness or Heat resistan

When ce) is poor and the focusing property is excellent, the smoothness or sizing is poor, and when a large amount of anionic surfactant having excellent sizing property is used, the smoothness and heat resistance are poor (Japanese Patent Laid-Open No. 73-22793). Nos. 73-64294, 73-82195 and 74-31994).

In order to solve this problem, the present invention has various performances required for the woolen spinning emulsion according to production facilities or manufacturing conditions in the field during the spinning process of various synthetic fibers and natural fibers, and has the opposite performance as described above. The formulation was completed based on the ability of the chemicals to exert a synergistic effect by blending the components by specific formulation techniques.

Accordingly, an object of the present invention is to provide an oil-proof spinning emulsion composition having a low cost and excellent lubricity, emulsion stability and spinning properties when spinning.

The composition of the present invention for achieving the above object is 65 to 84% by weight of petroleum mineral oil, 5 to 10% by weight of polyoxyethylene alkyl ether (6 to 10 mol), polyethylene glycol monooleate 0 to 10 of molecular weight 450 to 800 Weight percent sieving oil glycerides 0-10 wt% isooctyl stearate 0-10 wt%, alkyl sulphate alkali metal salts 0-7 wt%, sulfated castor oil 0-10 wt% and other additives.

Looking at the present invention in more detail as follows.

As described above, in the present invention, since the requirements for woolen milk are diversified according to on-site production facilities or manufacturing conditions during the processing of various types of woolen leaves, each component is mixed by blending technology capable of having various required performances.

Petroleum-based mineral oil used in the present invention is used for the purpose of improving lubricity and smoothness in the product during the spinning process, it is preferable to use a mineral oil having a kinematic viscosity of 8cSt to 96cSt at 40 ℃ to 65 to 84% by weight, If the kinematic viscosity is less than 8 cSt, the lubricity is insufficient, and if the kinematic viscosity is higher than 96 cSt, there is a risk of contamination due to excessive viscosity.

In addition, if the amount used is less than 65% by weight, the lubricity may be degraded, and if the amount is used more than 84% by weight, the emulsification and degreasing properties may be deteriorated, resulting in mura and contamination, leading to problems in producing high quality fibers. May be generated.

The polyoxyethylene alkyl ether is used for the purpose of improving emulsification, wettability, detergency, and permeability to the product during the woolen spinning process, the amount is preferably 5 to 10% by weight. At this time, if the polyoxyethylene alkyl ether is less than 5% by weight, there is a risk that problems occur in the dyeing process after spinning, and in the case of more than 10% by weight, lubrication, smoothness and concentration decrease, fiber cutting is generated. do. Moreover, it is preferable that polyoxyethylene has a mole number of 6-10 mol.

In the present invention, polyethylene glycol monooleate having a molecular weight of 450 to 800 used at 0 to 10% by weight, rapeseed oil glyceride, isooctyl stearate and sulfated castor oil to be used at 0 to 10% by weight, respectively, And it is used for the purpose of improving the lubricity, the alkyl sulfate alkali metal salt used in 0 to 7% by weight is used for the purpose of improving the antistatic property, sodium or potassium salt is preferable as the metal salt. The components are selectively added according to field production equipment or manufacturing conditions in various processes of the woolen industry, and specific examples thereof are described in the Examples.

Other additives used in the present invention include 0-5 wt% oleic acid, 2 wt% or less potassium hydroxide (48.5% KOH), 0-5 wt% ion-exchanged water and 0-5 wt% potassium acetate (CH ₃ COOK), the oleic acid is used as an emulsifier, potassium acetate is used as an emulsifier dispersant, and when the pH of the emulsion is less than 6, there is a risk that the rot and discoloration of the solution may be promoted. Adjust with In addition, ion-exchanged water is used as a viscosity control and emulsifier of the stock solution.
