Abstract
The present invention belongs to the field of textile processing, particularly to a moisture penetrating processing method of a polyester fabric. The polyester fabric is placed into a processing slot, and then pressure is pumped to be lower than 0.01 Torr by a vacuum pump. Non-polymerizability gas is supplied, and the pressure is adjusted to be from 0.05 to 5 Torr. The electric discharging frequency is from 1KHz to 100MHz, the power is from 5 to 400 W, the processing time is from 3 to 300 seconds, and the low-temperature plasma of the non-polymerizability gas is used for processing the polyester fabric. Then, an amino acid water solution is used for finishing the polyester fabric, the low-temperature plasma of the non-polymerizability gas is reused for processing, and thus, amino acids are polymerized in a crosslinking mode to form a water insoluble polymer film to be fixed on fibers. The present invention provides the polyester fabric processing method which has the advantages of good moisture penetration and slip surfaces. The processed fabric has good hand feeling and lasting effect.
Description
The invention belongs to the textiles manufacture field, particularly the saturating wet processing methods of polyester textile.
Polyester textile has good intensity and stability, and it is heat-resisting, fast light, acid and alkali-resistance, antioxidant and better performances such as wear-resisting.But the polyester textile hygroscopicity is poor, and the ability that its fabric sees through the high hot sweat gas of skin drainage is that poisture-penetrability is poor, accumulates static easily on fiber, thereby has influenced people's wearing comfortableness.
In order to improve the hygroscopicity of polyester textile, reduce surface electrostatic, improving snugness of fit, people improve polyester textile constantly attempting, as with acrylic acid, methacrylic acid etc. fiber being carried out grafting; With the compound copolymerization that contains hydrophilic radical or be mixed and made into polymer or the like.But preceding a kind of method is the treatment effect poor repeatability not only, and can cause the reduction of fibre strength and dyefastness; A kind of method in back then can influence the spinnability or the intensity of fiber.
In order to overcome the defective of said method, people have developed the method for utilizing Polyester Treated with Low Temperature Plasma fiber or fabric.Promptly generate hydrophilic radicals such as carboxyl, hydroxyl, amino at fiber or fabric face, improve the hydrophily of fabric by Low Temperature Plasma Treating.But the hydrophilic group that generates enters into the fibre-forming polymer internal layer along with the motion of fiber molecule chain, can not keep effect for a long time.
Use the fabric after Low Temperature Plasma Treating amino acid is put in order among the Japanese patent laid-open 5-295657.Promptly earlier flood polyester textile with amino acid solution, Low Temperature Plasma Treating is used in the back, makes the amino acid cross-linked polymeric, be bonded on the fiber, thus the polyester textile of the hygroscopicity of obtaining and good hand touch.But polyester fibre surface is hydrophobicity, has influenced the absorption of amino acid on fiber.
The objective of the invention is to overcome the defective of above-mentioned prior art when handling polyester textile, a kind of saturating wet processing methods of polyester textile is provided, makes the amino acid cross-linked polymeric, form water-fast polymeric membrane, be bonded on the fiber, obtain the polyester textile that hygroscopicity and persistence further improve.
Technical scheme of the present invention is: with non-polymerization gas low temperature Cement Composite Treated by Plasma polyester textile, generate hydrophilic radical at fiber surface earlier, increase the absorption affinity of amino acid to fiber.Then this fabric is put in order with amino acid solution, used non-polymerization gas low temperature Cement Composite Treated by Plasma at last again, make the amino acid cross-linked polymeric, form water-fast polymeric membrane, be bonded on the fiber.
Described non-polymerization gas low temperature Cement Composite Treated by Plasma is meant puts into treatment trough to fabric, then the pressure in the treatment trough is evacuated to below the 0.01Torr with vavuum pump, feeds non-polymerization gas, and pressure regulation power is 0.05～5Torr, preferred 0.1～1.0Torr; Between the electrode that treatment trough is placed, apply voltage and carry out glow discharge, carry out Low Temperature Plasma Treating; Applying the voltage discharge frequency is 1KHz～100MHz, preferred 13.56MHz, and power is 5～400W, preferred 20～300W, 3～300 seconds processing times, preferred 5～60 seconds; Then this fabric is put in order with amino acid solution, used non-polymerization gas low temperature Cement Composite Treated by Plasma at last again, make the amino acid cross-linked polymeric, form water-fast polymeric membrane, be bonded on the fiber.
During above-mentioned Low Temperature Plasma Treating, if vacuum is low excessively, the mean free path of electronics is little, electronics energy from the external electric field acquisition in a collision cycle is little, thereby energy is high enough to excite the number of electrons of ionized gas molecule or atom few, the number of active particle is few in the plasma atmosphere, and energy is low, acts on the weak effect behind the wool surface; If vacuum is too high, gas is thin, and number of particles itself is just few, can be used for exciting, the number of particles that ionization generates active particle just still less, thereby it is few to act on the number of particles on wool surface, two opposite factors make when vacuum is moderate, just can obtain best treatment effect.During Low Temperature Plasma Treating, if discharge power is too little, the then required processing time is long; If power is too big, and discharge instability reacts bad control.If processing time does not have effect too short; If long, bigger to fibre damage.
Described non-polymerization gas low temperature plasma is meant that self does not carry out the gas of polymerization under plasmoid, as air, O
2, N
2, H
2, CO
2, Ar, He, NH
3Deng the low temperature plasma of gas or their mist, make the ionization or excite under low-pressure state of these gases with electric energy.
Described amino acid is the amino acid that has acidic-group and basic group in alanine, Gly, L GLU or the silk amino acid equimolecular.
Describedly can use commonsense methods such as dipping, spraying or coating when handling fabric with amino acid.Wherein Jin Zi method is simple to operate, and finishing agent can fully contact with fiber, helps obtaining better effect.
