Detailed description of the invention
Synthetic fiber finishing agent of the present invention uses when manufacturing synthetic fiber, contains with the ratio specified the finishing agent of specific glyceride compounds (A) and specific branched ester component (B).Below, be described in detail.
[glyceride compounds (A)]
Glyceride compounds (A) be structure after the straight chain fatty acid with glycerine and carbon number 8 ~ 22 forms ester bond and the ratio shared in this straight chain fatty acid entirety of the straight chain fatty acid of carbon number 16 ~ 18 be more than 90 % by weight ester.Glyceride compounds (A) can use a kind or two or more.The ester compounds that glyceride compounds (A) is envisioned for natural esters or is obtained by natural esters, the aliphatic acid therefore forming ester is straight chain fatty acid.In addition, straight chain fatty acid is not by single Fatty acid compositions, can by Fatty acid compositions more than 2 of carbon number 8 ~ 22.
The glyceride compounds (A) used in the present invention is natural esters or the ester that obtained by natural esters, is envisioned for the compound not carrying out ester exchange.As glyceride compounds (A), directly can use and from the natural natural esters that obtain such as natural fruit, seed or flower or can use as required, natural esters is separated, refine etc. and the ester compounds that obtains.Therefore, as glyceride compounds (A), to be envisioned for be synthetic ester except making aliphatic acid obtain with glycerine reaction, two or more natural esters (grease) is carried out ester exchange and the ester obtained, natural esters and fatty acid ester and glycerine to be mixed and material except the ester carrying out random ester exchange and obtain.
Form the straight chain fatty acid of glyceride compounds (A) to be carbon skeleton be the aliphatic monocarboxylic acid of linear chain structure.Hydroxy fatty acid can be contained in straight chain fatty acid, but if containing hydroxy fatty acid, then the effect as smooth agent of this finishing agent is insufficient, therefore preferred not hydroxyl aliphatic acid.Straight chain fatty acid can be saturated, unsaturated in any.
The carbon number of straight chain fatty acid is 8 ~ 22, preferably 12 ~ 18, more preferably 16 ~ 18.When this carbon number is less than 8, oil film dies down, and there is the situation producing burr.On the other hand, if this carbon number is more than 22, then friction uprises, and flatness is deteriorated, and there is the situation producing burr.
As the straight chain fatty acid of carbon number 8 ~ 22, such as, can list: sad, capric acid, laurate, myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, elaidic acid, linoleic acid, linolenic acid, eicosenoic acid, behenic acid, cetoleic acid, erucic acid, castor oil acid etc.Wherein, as straight chain fatty acid, preferred myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, further preferred palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid.
