Abstract

A softening agent for bast yarns is prepared from mixed machine oil, polyoxyvinyl castor oil and anionic surfactant through proportioning, preparing mixed oil and mixed agent, emulsifying the mixed oil and mixed agent and preparing the softening agent. Its advantages are high softening effect, low cost and simple preparing process.

Description

A kind of bast softening agent and production method thereof

A kind of bast softening agent belongs to the bast softening agent that is used for the softening dimity in the textile technology field.

Mainly be the dimity to be softened in the prior art with oil.Producer adopts the byproduct of oil refining more, cooperates the back to push out with the poly-press of gear with female soap that rosin, alkali ebuillition of heated were made in 4-7 hour, behind the dilute with water and make.This bast softening agent has peculiar smell, and is poor to the bating effect of the dimity, and end breakage rate is high and produce complexity, and cost is higher.

It is effective to the purpose of this invention is to provide a kind of softening, the bast softening agent of the low and free from extraneous odour of end breakage rate, and production method is simple, low, the easy-operating production method of cost is to overcome the deficiencies in the prior art.

Bast softening agent of the present invention is such: mix in proportion with machinery oil, make mechanical mixture oil, add Emulsifier EL-60 and stir back adding anionic surfactant, dilute with water and make bast softening agent of the present invention, wherein machinery oil is to use the machinery oil of 5#-10# and 30#-46# in 1.0: the ratio of 1.2-2.0 cooperates, the Emulsifier EL-60 addition is (weight of establishing mechanical mixture oil is 80), mechanical mixture oil: Emulsifier EL-60 is 80: 0.8-1.2, the addition of anionic surfactant is that mechanical mixture oil is 80 with the anionic surfactant ratio: 0.8-1.2.

Production method of the present invention is such: 1, press 1.0 with the machinery oil of 5#-10# and 30#-46#: the mixed of 1.2-2.0, make mechanical mixture oil, and setting its weight portion is 80; 2, get 5 parts of mixing machinery oil, add polyoxyethylene 0.4-0.8 part, stir, get intermixture; 3, add anionic surfactant (emulsifying agent) in intermixture, addition is 0.8-1.6 part, stirs, and gets the emulsification intermixture; 4, the mechanical mixture oil that adds 75 parts in the emulsification intermixture adds while stirring, and gets emulsification machinery miscella; 5, the Emulsifier EL-60 that adds 0.4-0.8 part again in emulsification machinery miscella stirs, and makes the oyster white paste.

Above-mentioned bast softening agent can be diluted with entry, and the addition of water is a mechanical mixture oil: water is 80: 1.0-2.0.

Mixing machinery oil is with the machinery oil of 6#-8# and 34#-40#, in 1 in this bast softening agent: the ratio cooperation of 1.4-1.8 and the bast softening agent that makes, effect is better.

Describe embodiments of the invention below in detail

1, with the 6# machinery oil of 48 parts 39# and 32 parts mixed mechanical mixture oil, with 1 part of Emulsifier EL-60,1 part of anionic surfactant, add 1.5 parts of water again after stirring and make bast softening agent through mixing.

2, the bast softening agent among the embodiment 1 makes with the following method:

1), with the machinery oil of 6# and 39# mixed by 2: 3, make 80 parts mechanical mixture oil; 2), get 5 parts mechanical mixture oil, add 0.5 part Emulsifier EL-60, stir, intermixture; 3), in intermixture, add 1 part of anionic surfactant (emulsifying agent), stir, the emulsification intermixture; 4), in the emulsification intermixture, add 75 parts mechanical mixture oil, add while stirring, emulsification machinery miscella; 5) Emulsifier EL-60 that adds 0.5 part, again in emulsification machinery miscella stirs, and makes the oyster white paste, adds 1.5 parts the water agitation and dilution and must bast softening agent.

Bast softening agent of the present invention has that bating effect to the dimity is good, end breakage rate is low, becomes This is low, and its production method is simple, easy-operating advantage. Be applicable to when producing gunnysack and use Use in the softening dimity.
