Description
Technical field:
The invention discloses a kind of shitosan-polyester-polyether block copolymer hydrophilic finiss method of dacron, belong to textile finishing process technical field.
Background technology:
Terylene is the trade name of polyethylene terephthalate (PET) fiber, is one of the large main force of three in synthetic fiber fiber.Because terylene linear macromolecule is symmetry benzene ring structure, good linearity and molecular chain structure stereoregular, it is had, and intensity is high, good springiness and the rigidity superior physical and mechanical properties such as large, and weak acid, alkali are stablized, there is excellent DIMENSIONAL STABILITY and good corrosion resistance, it is a kind of ideal textile fabric, but, terylene is a kind of typical hydrophobic fibre, only respectively there is a hydroxyl at its molecule two ends, and without other hydrophilic radical, molecular structure is close-packed arrays, degree of crystallinity is high, and hygroscopicity is poor.In normal conditions (20 DEG C of relative humidity 65%), the hydroscopicity of terylene only has about 0.4% (cotton 7-8%, polyamide fibre 4%, acrylic fibers 1-2%), and under the condition of 100% relative humidity, hydroscopicity is also only 0.6-0.8%.Therefore its hygroscopicity poor, easily produce electrostatic, easily stain, affect its snugness of fit.
Hydrophilic finiss, is referred to as water suction (or absorbing sweat) at first and arranges, and is to be suggested for the advanced motion clothes based on dacron or training clothes.Endowing terylene fiber or fabric hydrophilic mainly contain two kinds of methods: one is spinning modification: in the spinning process of fiber, utilize the synthetic technology of fiber to carry out modification to Structure of PET Fiber, make polyster fibre itself have hydrophilicity, thus improve the wearability of terylene; The method process routes relative complex, operability is more weak.Two is arrange modification: mostly at fiber surface modification, utilize dacron afterfinish technology and reach modification object.Namely on terylene macromolecular chain, introduce hydrophilic radical, make fabric face form hydrophilic layer, thus change fiber surface performance.
The method of spinning modification mainly contains at present: polymer molecular structure hydrophiling, hydrophilic component graft copolymerization, microporous, heteromorphosis etc. with hydrophilic component compound co-spun yarn and fibre structure.
Polymer molecular structure hydrophiling: by polymerization or the mode of copolymerization, introduce hydrophilic radical in the macromolecular basic structure of terylene, improves the hydrophily of terylene.But it is very limited to improve hydrophilic degree, and the copolymerization efficiency of polar compound and terylene is very low.Polymerization process also can weaken the crystallizing power of terylene greatly, reduces its fusing point, affects its spinning, have harmful effect to the physical and mechanical properties of fiber, therefore strictly will control the consumption of hydrophilic monomer.
Hydrophilic component graft copolymerization: hydrophilic component will be had as side chain, and polyester macromolecule carry out grafting, obtains modified polyester fibre, endowing terylene hydrophilicity.
Hydrophilic component compound co-blended spinning: before spinning, hydrophilic compounds or the modified poly ester containing hydrophilic radical are mixed into high polymer molten, and spin processes carries out spinning routinely, can obtain a kind of Hydrophilic Polyester Fiber fiber, thus promotes the hydrophily of fiber.Though the research improving terylene hydrophilicity about compound co-blended spinning method is many, spinning solution is unstable mostly, and spinning process is influenced, and the washability of the Hydrophilic Polyester Fiber fiber of spinning is also bad.
The microporous of fibre structure, heteromorphosis: the microporous of fibre structure is for the purpose of the morphosis changing fiber, makes fibre structure fibrillation, have the inside and outside through micropore of the natural fabric such as many picture hairs or cotton, utilize capillarity to make fibrous absorbent.But this method can only improve water absorbing properties, the hygroscopicity of fiber can not be improved.
Arrange modification: carry out hydrophilic modifying on the surface of polyster fibre or fabric, its essence is and form one deck hydrophilic film on the surface of fiber or fabric, improve the hydrophilicity of PET fiber surface.The method technique is simple, but not durable, therefore also should promote the durability of polyster fibre hydrophilicity.Arrange method mainly hydrophilic monomer or polymer surfaces graft polymerization method, other process (plasma modification and Silk Fibroin Coating Finishing etc.) of fiber surface and the absorption set method etc. of hydrophilic finish agent of modification.
Current hydrophilic finishing agent has a variety of, is generally divided into polyesters (polyester polyethers, sulfonated polyester and mixed type polyester), polysiloxane-based, the type such as polyurethanes, polyacrylate, polyamine class and shitosan class.
Although polysiloxane-based hydrophilic finishing agent is applicable to dacron etc. close arrangement that is fine and BLENDED FABRIC, hydrophilic durability is poor; Though polyurethanes hydrophilic finishing agent is good to the impregnability of dacron and wettability, it has low temperature dissociative, can be few for kind; Polyacrylate hydrophilic finishing agent is difficult to balance between the hydrophilicity and feel of fabric, and resultant effect is bad; During polyamine class hydrophilic finishing agent processing fabric, washability is poor, easy yellowing, is mainly used in acrylic fibers and BLENDED FABRIC thereof; Although shitosan class hydrophilic finishing agent asepsis environment-protecting, the hydrophilicity of finish fabric is better, and its operating cost is higher, complex procedures, and washability is poor.And polyester polyethers hydrophilic finishing agent can to get both good hydrophily and washability when arranging dacron, but the polymer molecular structure of synthesis is regular, degree of crystallinity is higher, poorly water-soluble, easily assemble in water, affect use and the effect of finishing agent, therefore need in use first will carry out emulsification, the rear method finish fabric adopting dipping or pad, but its poorly water-soluble causes dyeing together, and bath effect is bad.
The people such as Sui Yanling disclose the document of a section by name " shitosan-polyester polyether-type hydrophilic finishing agent " in " printing and dyeing " magazine disclosed in 2010: by polyester polyether-type hydrophilic finishing agent KL-WPS and shitosan composite, hydrophilic finiss is carried out to polyester textile.Result of the test shows, hydrophilic finishing agent consumption 60g/L, both compound proportions are 1:1, the hygroscopicity of polyester textile, wet guilding, pollution resistance and antistatic behaviour etc., the effect of all single than use polyester polyethers hydrophilic finishing agent will be well of the present invention closest to prior art, but shitosan use amount is larger in this invention, because shitosan cost is higher, process operation high expensive, hydrophily and the washability effect of the rear dacron of its arrangement of the method are simultaneously excellent not, especially resistance to water effect is not ideal enough, has much room for improvement.
Summary of the invention:
The object of the invention is to for the deficiencies in the prior art, overcome polyether polyester class hydrophilic finiss and, complex procedures, washability and poorly water-soluble high with shitosan class finishing agent operating cost in hydrophilic finiss process, the dissatisfactory shortcoming of hydrophilic effect, a kind of shitosan-polyester-polyether block copolymer hydrophilic finiss method of dacron is provided, the method operating cost is low, technique is simple to operation, low toxicity low stain, after arranging, fabric has good washability and hydrophily.
