Problems solved by technology

In practical application, there are two main series of spinning sizing: one is polyvinyl alcohol sizing, which is recognized as the best cohesiveness in viscose spinning sizing, but its The size film is hard, and the finished cloth feels poor after desizing, which is the main reason for the gradual reduction in the amount of size used
In addition, the decomposition cycle is long, which is easy to cause pollution to the environment, and its use has been restricted in some developed countries.

Embodiment Construction

[0007] Preparation of oil agent: The process conditions are that 60 parts of white oil are added to the reaction kettle lined with ceramics. The white oil is a mixture of sulfonated vegetable oil and mineral oil, and 10 parts of leveling agent. The leveling agent is emulsified by quaternary ammonium salt 15 parts of emulsifier, the emulsifier is the condensation product of castor oil and ethylene oxide, the chemical structural formula is, RCOO(CH 2 CH 2 O) n H, n=8-12. R=C 16-18 Alkyl, the softener is formed by condensation of one molecule of stearic acid and six molecules of ethylene oxide. The above material components are in the reaction kettle, which is equipped with a heating jacket and agitator. Turn on the agitator, open the steam valve to heat the material to 65°C, continue to stir for 16 hours, add 84 parts of soft water and mix evenly to make into an oil agent, then 91.7 normal temperature desalted water and existing 6 parts of polyacrylate, and then prepare 2 pa...

Abstract

The present invention discloses an environment-protecting type size mixture for adhesive filament continuous spinning. It is characterized by that (1). preparing oil agent; adding 60-61 portions of white oil, 10-11 portions of level dyeing agent, 15-16 portions of emulsifier and 10-11 portions of softening agent into a reactor still with ceramic lining, heating to 65-70 deg.C, stirring for 16 hr., then adding softened water 80-85 portions, mixing uniformly to obtain oil agent; and (2). adding 6-7 portions of polyacrylic ester, 0.2-0.3 portion of germicide and 89-90 portions of desalinized water into 2-3 portions of prepared oil agent, stirring for 16 hr. in preparation tank so as to obtain the invented size mixture for continuously spinning viscose filament.

Description

(1) Technical field: [0001] The invention relates to a spinning slurry, which is an environment-friendly slurry especially suitable for continuous spinning of adhesive filaments. (two) background technology: [0002] In the production of continuous spun viscose filaments, the viscose filaments produced by the spinning machine are untwisted parallel filaments, and the fibers need to be embraced with each other by means of slurry (oil agent). The slurry forms a lubricating serous film with sufficient strength, bonding fastness, elasticity and lubricity around the filaments to prevent the filaments from being damaged during the movement and winding process to form fuzz or break ends. The cohesion ability of the size has an important influence on the spinning process and the quality of the silk. The size should have good washability, so as to facilitate the finishing of textiles, so that bleaching, dyeing, printing and other processes can be carried out smoothly. Desizing effe...
