Problems solved by technology

The choice of lubricant has a very critical effect on the spinning performance. If the viscosity of the lubricant is too high, it is not conducive to improving the uniformity and spinning speed of the DTY oil when oiling, and it is easy to cause wool and broken ends; if the viscosity is too low, the It is easy to cause splashing of oil agent, which is not conducive to improving the oiling rate

preparation example 1

[0037] Preparation example 1, a polydimethylsiloxane emulsion, was prepared according to the following method:

[0038] S101: Dissolve 30g of sodium dodecylsulfonate and 9g of OP-10 in 3L of water under stirring, continue to stir and heat up to 70°C, add 400g of octamethylcyclotetrasiloxane and 100g of tetramethyl tetrasiloxane The mixed solution composed of vinyltetrasiloxane was stirred for 2 hours at a speed of 200 rpm to obtain a pre-emulsion;

[0039] S102: Add 5g of p-toluenesulfonic acid (initiator) to the pre-emulsion, stir and heat up to 80°C, stir at a constant temperature and react for 7h to obtain a reaction solution, then drop to room temperature, add sodium bicarbonate solution (buffer) to adjust The pH value was 7, and a polydimethylsiloxane emulsion with a viscosity (at 25° C.) of 350 mm2 / s was obtained.

preparation example 2

[0040] Preparation example 2, a polydimethylsiloxane emulsion, was prepared according to the following method:

[0041] S101: Dissolve 60g of sodium dodecylsulfonate and 15g of OP-10 in 5L of water under stirring, continue to stir and heat up to 80°C, add octamethylcyclotetrasiloxane with a mass ratio of 450g and 90g A mixed solution composed of tetramethyltetravinyltetrasiloxane was stirred for 3h at a rotating speed of 500rpm to obtain a pre-emulsion;

[0042] S102: Add 8g of p-toluenesulfonic acid (initiator) to the pre-emulsion, keep a constant temperature at 85°C and stir for 10h to obtain the reaction solution, then drop to room temperature, add sodium bicarbonate solution (buffer) to adjust the pH value 7. Obtain a polydimethylsiloxane emulsion with a viscosity (at 25° C.) of 900 mm2 / s.

preparation example 3

[0043] Preparation example 3, a polydimethylsiloxane emulsion, was prepared according to the following method:

[0044] S101: Dissolve 20g of sodium dodecylsulfonate and 7g of OP-10 in 3L of water under stirring, continue to stir and heat up to 70°C, add 420 g of octamethylcyclotetrasiloxane and 80 g of tetramethyl tetrasiloxane The mixed solution composed of vinyltetrasiloxane was stirred for 2 hours at a speed of 200 rpm to obtain a pre-emulsion;

[0045] S102: Add 5g of p-toluenesulfonic acid (initiator) to the pre-emulsion, stir and heat up to 80°C, stir at a constant temperature and react for 6h to obtain a reaction solution, then drop to room temperature, add sodium bicarbonate solution (buffer) to adjust The pH value was 7, and a polydimethylsiloxane emulsion with a viscosity (at 25° C.) of 200 mm2 / s was obtained.

Abstract

The invention discloses a DTY (Draw Textured Yarn) oiling agent and DTY filaments. The DTY oiling agent comprises the following raw materials in parts by mass: 70-80 parts of a lubricant; 2-6 parts of an anti-splashing agent; 1-3 parts of an antistatic agent; and 5-10 parts of an emulsifier. The lubricant is prepared from industrial white oil and polydimethylsiloxane emulsion in a mass ratio of (15-18): 1; the viscosity of the industrial white oil is 3-10 mm < 2 > / s; and the viscosity of the polydimethylsiloxane emulsion is 300 to 1000 mm < 2 > / s. According to the DTY oiling agent disclosed by the invention, the lubricant is obtained by compounding the industrial white oil and the polydimethylsiloxane emulsion, so that the oiling rate and the splashing resistance of the DTY oiling agent can be effectively improved, the oiling uniformity of the oiling agent is guaranteed, and the phenomena of broken filaments and broken ends are reduced.

Description

technical field [0001] The invention relates to the field of chemical fiber spinning, in particular to a DTY oil agent and DTY silk. Background technique [0002] DTY oil is an important raw material in the DTY texturing process. DTY oil usually contains lubricants, antistatic agents, emulsifiers, clustering agents and anti-splashing agents, etc., which can improve the smoothness, antistatic properties, and unwinding of fibers. Sex, clustering and other properties, so as to reduce the fiber wool, broken ends and other undesirable phenomena in the high-speed spinning process. [0003] The main components of the oil agent are usually mineral oil, vegetable oil and synthetic ester, etc., which are used as lubricants to reduce the frictional resistance between spinning and equipment during high-speed spinning. The choice of lubricant has a very critical effect on the spinning performance. If the viscosity of the lubricant is too high, it is not conducive to improving the unifor...
