Description
The present invention relates to a kind of method of modifying of synthetic fiber and the synthetic fiber after the modification thereof, more specifically, the present invention relates to a kind of polyester fiber high-moisture-absorption modified method and high-moisture-absorption modified after polyester fiber.
Polyester fiber (with polyster fibre, that is, the ethylene glycol terephthalate structure is main) is since invention, and with its significant characteristic, that is, cost is low, intensity is high, good, the ironing free shaped performance of detergency ability obtains application more and more widely greatly.Yet this area knows that all the inherent shortcoming that polyester fiber has is: its hygroscopicity extremely low (regain only 0.4%, for minimum in all fibres), breathable moisture permeability is poor, easily static electrification.Thus, make that again the wearing comfort, absorbing sweat water-based of polyester fiber can be relatively poor, its application is very restricted.Thus, also make above-mentioned polyester fiber fail to bring even more ideal effect to some Application Areas.
For improving the wearing comfort energy such as hygroscopicity of polyester fiber, improve the result of use of polyester fiber and enlarge its range of application, people expect to improve the polyester fiber moisture pick-up properties strongly.The hydrophilic finish research that polyester fiber is done is promptly arisen at the historic moment.
What people at first had in mind is the wearability of improving polyester fiber.For this reason, people also once achieved the above object by the cutting of clothes, the design of clothes fashion and the methods such as combination of the used fiber of garment material.Yet well-known, said method also fails fundamentally to improve the wearability of fibers such as polyster fibre.For example, for the sports clothes that moisture pick-up properties is had relatively high expectations, before the high-hygroscopicity modified dacron of durability came out, these most type games clothes normally adopted so-called functional knitted fabric to make.That is, adopt hydrophobic polyester fiber at described knitted fabric internal layer, its skin then is made up of hydrophilic fiber.So, make that being in the hydrophobicity polyester fiber that pastes the skin internal layer can be transferred to the big skin of hygroscopicity with moisture from skin surface by the fiber hair areolar, makes moisture atomize at skin, evaporation, by this, make the polyester fiber of contact skin be in drying regime all the time.Yet said method makes that prepared clothes are more thick and heavy, also fails to solve the static electrification problem of described inner textile layer hydrophobic fibre, has again, and described moisture absorption mechanism makes its moisture pick-up properties relatively poor.
Have found that, use hydrophilic softening agent or hydrophilic finish agent that polyester fiber is carried out the hygroscopicity modification and handle, can improve the hygroscopicity of polyester fiber.For example, the 5th, 069, No. 847 United States Patent (USP)s authorizing T.H.Grindstaff have disclosed the spinning treatment fluid that a kind of usefulness contains caustic soda and have handled not drawn polyester fiber long filament, and it is hygroscopic to improve, the MODIFICATION OF POLYESTER FIBER method.Yet, this fibre spinning stage to the modification processing method that polyester fiber carried out, as what domestic existing people did, the moisture pick-up properties of polyester fiber is not made bigger contribution; It is bigger to the dyefastness influence; The durability of its moisture pick-up properties is relatively poor; So, be not used widely.
In addition, (CN 89102678.9, CN89101586.8) disclosed a kind of surface property method of modifying of polyester fiber for the 8th, 806, No. 419 United States Patent (USP)s of du pont company.Described method is by a kind of smoothing agent coating of being made up of modified copolyesters of coating on polyester fiber, and gives described fiber with improved hygroscopicity and durability thereof, and decontamination, surface property such as curling.The described smoothing agent coating of being made up of modified copolyesters has polyether segment and polyester key, and has the residue of the mixture of polar group as hydroxyl, quaternary amine base etc.By this, provide the degree of cross linking of this coating, improved the durability of bonding force, hydrophily, surperficial feel and the coating of fiber with bigger cross-linking reaction.Yet,, and fail on bigger degree, to improve the hygroscopicity of polyester fiber though described coating processing method has been improved the fiber surface feel.
In recent years, it is raw material that the technical research personnel of numerous in the world relevant this areas have carried out with the terylene waste, by to its appropriateness degraded and thereafter with the copolyreaction of epoxide, the research of the high moisture absorption finishing agent of terylene of preparation durability.Described research system is used for the dip-dye operation of High Temperature High Pressure with described high moisture absorption finishing agent, and the polyester fiber as terylene etc. in the exhaust dyeing technology is carried out high-moisture-absorption modified processing, has obtained a series of fruitful achievements.This type of high-hygroscopicity finishing agent has realized that the kind of suitability for industrialized production mainly contains: the QCX of Luo Na-Rhone-Poulenc of France and CX, the SR series of products of Japanese high terebinth Chemical Co., Ltd, HYDROLON and HYDROWICK product, the INTERA series of products of American I NTERA company and the HYDROWELL product that Yanyun Textile Chemical Co., Ltd., Shanghai produces of U.S. CONSOLICATED LABS INTERNATIONAL company.
The specific of above-mentioned high moisture absorption finishing agent is: they all are the very excellent hydrophilic finish agent of washing fastness, can adopt exhaust process and DISPERSE DYES with bathing, and the normal polyester fiber is carried out high-moisture-absorption modified processing.
Again, above-mentioned high moisture absorption finishing agent normally utilizes the terylene waste fiber after the appropriateness degraded, generates with hydrophilic epoxide (copolymerization) reaction.Thus, described high-hygroscopicity finishing agent is to contain terephthalic acid (TPA) ester moiety (or residue, segment, repetitive or key) from described terylene waste and ethylene glycol terephthalate part (or residue, segment, repetitive or key) and the mixture or the compound of copolyester polyether segment, that contain polyether segment of polyoxyethylene (or polyoxyalkylene) segment that is attached thereto.
Use above-mentioned mixture or the compound that contains the copolyester of polyether segment, can pass through chemistry route, the polyester fiber that a kind of hydrophilic polymer is grafted to as polyster fibre gets on, thereby, make described polyester fiber obtain hydrophily and moisture laser propagation effect, and the anti-degree of sucking after its finishing agent arrangement is also excellent especially.
Yet, use the mixture of the above-mentioned copolyester that contains polyether segment or compound as the shortcoming of high-hygroscopicity finishing agent to be: it can promote the enhancing of moving property of thermophoresis in dye liquor, therefore, this series products often can only be applicable to the exhaust process of High Temperature High Pressure, does not pad technology and be suitable for.Thus, it is evident that, when using above-mentioned hydrophilic finish agent that polyester fiber is carried out high-moisture-absorption modified processing, must use the high-temperature pressure dyeing cylinder of intermittent operation, can't carry out the high exhaust dyeing of efficient and handle, can't improve treatment effeciency; Owing to used the high-temperature pressure dyeing cylinder of intermittent operation, can't avoid the aberration between the staining jar, can not guarantee the even dyeing between batch cloth; Because moving property of thermophoresis makes the active ingredient of described finishing agent at high temperature can't be evenly distributed in the polyester fiber, influence its rate of water absorption and fastness to washing again.
