Abstract
The invention discloses is a kind of softening agent for processing bast fibers, the character lies in: the softening agent contains soft smoothing agent 20-90 shares, the surface activating agent is 1.5-50 shares. The softening agent is made up of by mixing the soft smoothing agent and surface activating agent under a preset temperature and time. The softening agent may form a layer of soft and smooth film on the surface of the processed bast fiber, covers the viscous polyoses remained on the bast fiber, and it prevents the bonding of bast fibers. The process is simple, and the operation is convenient. The manufacturing temperature is temperate, the energy consumption is low.
Description
One, technical field
The invention belongs to the natural plant fibre processing technology field, be specifically related to a kind of flexibilizing agent of handling bast fiber and preparation method thereof that can be used for.
Two, background technology
Bast fiber is the big class of one in the natural plant fibre, the mulberry fibre that the principal item that has been employed has flax fibre such as hemp, flax, ramie and developing.The research and development of bast fiber for those countries and regions that are not suitable for plant cotton and abound with bast-fibre, mulberry fibre, have great economic implications and social effect undoubtedly.
Bast fiber is that the form with fibre bundle is present in plant cortex inside, the colloid of being formed by hemicellulose, pectin, lignin etc. coats wherein, fibre bundle therefrom be separated, and makes it can become textile material, except that removing the epidermis, coming unstuck is the key of bast and fiber separation.The colloid of bast fiber is hundred-percent takes off to the greatest extent because existing bast fiber degumming technology also can't make, residual a small amount of polysaccharide material then will cause the adhesion of bast fiber, form hard silk, doubling and stiff silk, make the fiber wiriness on the one hand, cause difficulty on the other hand shredding, the combing of the spinning of road, back, thereby all will be in the processing procedure of bast fiber to the fiber after coming unstuck, handle with the oils softener, alleviate gluing also of fiber, reduce the waste silk rate, increase the flexibility and the elasticity of fiber, satisfy weaving and take performance demands.
At present, the softener of handling bast fiber is that main component is tea oil, rapeseed oil, mineral oil emulsion etc. at traditional softener of bast-fibre exploitation.Because it is formed for oily matter, thereby in order to guarantee that it can, diffusion wetting fully at fiber surface, generally need cloudy supporting five to eight days, the cycle is long, and the indoor environment of handling also requires certain temperature, humidity assurance, and condition is harshness comparatively.Nonetheless, the sticking doubling phenomenon of fiber still also has 2~40% not to wait, and this not only can influence the fibrous finished product rate after shredding, the combing, also can be incomplete because of shredding, combing, cause the fault of textiles, and influence qualification rate.
Three, summary of the invention
The objective of the invention is the deficiency at prior art, provide a kind of bast fiber that makes to ease back rapidly, sticking doubling greatly reduces, the efficient flexibilizing agent that fiber is more fluffy.Another object of the present invention provides this method that can be used for handling the bast fiber flexibilizing agent of preparation.
Provided by the inventionly can be used for handling the bast fiber flexibilizing agent, it is characterized in that this flexibilizing agent contains 20~90 parts of the flexible smooth agents that can make the bast fiber surface form one deck flexible smooth film, 1.5~50 parts in surfactant, its umber is weight portion
Wherein flexible smooth agent is at least a in sorbitan fatty acid ester, sorbitan fatty acid ester polyoxyethylene ether, polyoxyethylene carboxylate, amido silicon oil, long-chain alkyl tertiary amine, higher fatty acids and salt thereof, the paraffin wax.The preferred carbon number of long-chain alkyl tertiary amine and higher fatty acids and salt thereof is 12~20, and paraffin wax preferred fusing point is 56~64 ℃.
Surfactant is any in alkylbenzenesulfonate, alkyl sulfate, fatty acid sulfate, succinate sodium sulfonate, alkylol polyoxyethylene ether sulfuric ester, alkylphenol polyoxyethylene sulfuric ester, alkylol polyoxyethylene ether phosphate, alkylphenol polyoxyethylene phosphate, alkylol polyoxyethylene ether, the alkylphenol polyoxyethylene.
Provided by the inventionly to can be used for handling the bast fiber flexibilizing agent and mix, deposit with stability in use better in order to make, the present invention also can take following technical measures:
(1) makes and provided by the inventionly can be used for handling that also to contain weight portion in the bast fiber flexibilizing agent be 0~80 part water;
(2) provided by the invention can be used for handling also be added with the pH regulator agent in the bast fiber flexibilizing agent, making its pH value is 4.5~7, the pH regulator agent is any in formic acid, acetic acid, ethanedioic acid, the hydroxycarboxylic acid.
The preparation method who can be used for handling the bast fiber flexibilizing agent provided by the invention, it is characterized in that at first 1.5~50 parts in 20~90 parts of flexible smooth agents and surfactant, add and be equipped with in the mixing kettle of agitator and thermometer, under 20~90 ℃ of temperature, mix and made it to become transparency liquid in 30~60 minutes; Continue under agitation to drip 0~80 part in synthermal water then; Adding follow-up continuation of insurance temperature stirred 30~60 minutes; Under agitation be cooled at last in the time of still guaranteeing that flexibilizing agent is in a liquid state, discharging or the agent of adding pH regulator, behind adjusting pH value to 4.5~7, discharging.
During use, the present invention is prepared can be used for handling in the hot water that bast fiber flexibilizing agent predetermined amounts joins 60~80 ℃ and dissolving of gained; bath raio is 1: 10~1: 20; the bast fiber input after will coming unstuck then wherein; handled 2~60 minutes down at 20~80 ℃; take out and dewater moisturely 50~60%, send into drying room again and be dried to moisture 6~10% and can carry out shredding, combing to fiber.
The present invention has the following advantages:
1, owing to contains flexible smooth agent in the flexibilizing agent that can be used for handling bast fiber provided by the invention, thereby bast fiber that can be after processing surface forms the film of one deck flexible smooth, viscous polysaccharide residual on the bast fiber is coated, prevent the bast fiber adhesion effectively, doubling can be reduced to about 1~20%, and make fiber soft, level and smooth, fluffy, and be convenient to shredding, combing, improve the row yielding of fiber.
2, provided by the inventionly can be used for handling the surfactant that contains in the flexibilizing agent of bast fiber, can not only make flexible smooth agent emulsification, can also make flexibilizing agent have good wetting, osmosis, improve treatment effect, and in the processing of back easily by eccysis.
3, can be used for handling the water that adds in the flexibilizing agent of bast fiber provided by the invention, not only have help that flexible smooth agent and surfactant mix, dilution and reduce the effect of consumption when using, also helpful flexibilizing agent is wetting, infiltration, the synergy that spreads.
4, owing to also be added with the pH regulator agent in the flexibilizing agent that can be used for handling bast fiber provided by the invention, and to make its pH value be 4.5~7, thereby this flexibilizing agent also has good depositing and stability in use.
5, preparation provided by the invention can be used for handling the method for the flexibilizing agent of bast fiber, and technology is simple, and is easy to operate, the preparation condition gentleness, and energy consumption is low, is convenient to control.
