Description

A kind of shrinkproof, crease-resistant softener

Technical field

The present invention relates to field of fabric producing technology, in particular, is a kind of shrinkproof, crease-resistant softener.

Background technology

External textiles chemical finishing, particularly finishing functions aspect comprise soft finish, non-ironing and arrangement, antistatic finish, ANTIPILLING arrangement, non-ironing and durable press finish, water and oil repellent finish, soil-releasing finiss, non shifting finiss, antistatic finish, ANTIPILLING arrangement, elastic finishing, antiultraviolet arrangement, antimicrobial finish, bio-finishing etc.Because softener can be given fabric with soft, comfort feel, therefore can improve the quality and the surcharge of fabric.This meets current pursuit clothes top grade, comfortable trend.Make the consumption of softener increasing, this has made the fast development of softener kind also shortly.Existing domestic softener kind just has hundreds of, division is as follows: 1, anionic softener: the anionic softener is except soap, sulfonation wet goods, and its main component is the anti-ionic compound of belt length alkanes such as butanedioic acid octadecanol ester sodium sulfonate, octadecanol ester sulfuric ester or anion, non-ionic compound.Generally have good wettability and heat endurance, can use with bathing, can be used as the softener of extra white fabric with fluorescent whitening agent.Also relatively be applicable to cellulose fibre, can give fabric water imbibition preferably, but its absorption to fiber is similar to direct dyes, more weak, so soft effect is relatively poor, and easily by flush away.In addition,, can be used for silk degumming, to prevent scratch (ash is hindered) because it has soft effect in the bath.2, nonionic softener: the nonionic softener is generally the fatty ester ester of polyoxyethylene ester (or ether), pentaerythrite or the anhydrous sorbitol of ten acid (or alcohol).Because the nonionic softener is poor to the adsorptivity of fiber than the ion-type softener, only can play smoothing effect.But it can share with the ion-type softener, and other compatibilities of ground are good, and are good to freeze thaw stability, and does not make the shortcoming of fabric xanthochromia, can be used as the soft finishing agent of no durability, also can make the important component part of synthetic fibre spinning finish.Its portioned product can be as the imitative silk finishing agent of fabric " scroop sound ".3, cationic softener: this class softener kind is more, is to use the most general softener at present.Mainly be because most of fibers have negative electrical charge in water, cationic softener is adsorbed on fiber surface easily, binding ability is stronger, high temperature resistant, the wash resistant of energy, and arrangement back fabric is plentiful smooth, can improve the ABRASION RESISTANCE and the tearing brute force of fabric, synthetic fiber are also had certain antistatic effect.Therefore be widely used in fabrics such as cotton, polyamide fibre, acrylic fibers, also have this kind to be applicable to silk.But partial cation type softener easily causes xanthochromia when high temperature, and with the decline of color fastness to light.Cationic softener generally is the derivative of octadecylamine or dimethyl octadecylamine or the condensation product of stearic acid and polyethylene polyamine.Can be divided into tertiary amines softener, quaternary ammonium salt softener again according to its structure, imidazoline quaternary ammonium salt class softener, two alkyl dimethyl quaternary ammonium salt softeners etc.4, amphoteric softener: the amphoteric softener is a class softener that develops in order to improve cationic softener.It is stronger to synthetic fiber affinity, does not have yellowing and makes disadvantage such as dyestuff variable color.The multiple experienced operation that also can be used for silk makes the silk feel better.The amphoteric softener also can use with cationic softener, plays synergistic function.This class softener is generally alkylamine lactone type structure.5, silicone softening agent: emulsion or microemulsion that this class softener is polysiloxanes and derivative thereof can make fabric have good softness and level and smooth feel.Product has emulsion polymerisation, and macromolecule silicone oil emulsification and through modification, the worker's glutinous rehmannia of producing such as composite has basically formed system, and the kind trade mark of supply is also more.But effect and performance still have very big-difference.1. dimethyl-silicon does not have emulsion: this is the product of using the earliest in silicone softening agent, and the SILOXANE MOLECULAR WEIGHT that is used as softener is generally 60,000-70,000.After arrangement, can give the feel that fabric is sliding, endure, feel well, reduce the coefficient of friction of fabric, and improve the ABRASION RESISTANCE and the seamability of fabric.But because of not having reactive group on its strand, thus can not react with fiber, can not self-crosslinking, and just draw by molecule and attached to fiber surface, so washability is relatively poor, the elasticity raising is also limited.2. organosilicon hydroxyl galact (hydroxy-silicone-oil emulsion): this is that China uses the widest silicone based softener the eighties in 20th century.Its relative molecular mass is generally 60,000-80,000, and relative molecular mass is big more, and flexibility and smooth feeling are good more.Because its molecule chain end and great basic end-blocking, therefore under the effect of crosslinking agent, catalyst, can or self take place crosslinked and be formed with certain flexible macromolecule membrane with the reactive Ji Xuan of fiber, therefore have washability, and can improve the elasticity of fabric.Organosilicon hydroxyl galact is divided into CATION organosilicon hydroxyl galact and anion organosilicon hydroxyl breast according to the ionic difference of the emulsifying agent of its use.Though there is hydroxyl in organosilicon hydroxyl galact at the end of strand, to improving its hydrophily and stability of emulsion certain help is arranged, but because the emulsion particle of organosilicon hydroxyl galact is difficult to tiny, the homogeneous of control, therefore the stability of emulsion also is difficult to grasp, when using, be prone to the floating oil phenomenon, make to occur the defects such as oil mark that are difficult to remove on the fabric.Therefore the stability of emulsion quality of organosilicon hydroxyl galact class softener also is the important indicator of its quality of evaluation.

Develop over past ten years very fast.Owing on siloxane molecule, introduced amino, improved its hydrophily, therefore select suitable emulsifying agent and preparation technology for use, can make it to become the microemulsion of particle diameter below 0.15 μ m.Because its particle diameter less than wavelength of visible light, does not have resistance to visible light, therefore can make emulsion become transparent.Just its particle grain size only be in the ordinary emulsion grain diameter 1/10, make in the microemulsion effectively that granule number has increased by 103 times, the touch opportunity of microemulsion and fabric increases greatly, and good in the fabric face spreadability, is penetrated into fibrous inside easily.Therefore this product can give fabric good soft inner degree, and this pliability is also more durable.Water-soluble, storage stability, the heat-resistant stability of microemulsion product, anti-shear stability generally also can be better.
