Description
Technical Field
The invention belongs to the technical field of wool processing, and particularly relates to a method for treating cashmere fabric by low-temperature plasma.
Background
The cashmere product has the advantages of lightness, softness, smoothness, heat preservation, comfort, soft luster, beautiful appearance, elegance and the like, has the reputation of soft gold and fiber diamond, is deeply loved by consumers and plays an important role in the textile market. The annual cashmere yield of China is about 16000t, which accounts for about 75% of the world yield, but the cashmere processing technology of China is slow to progress. At present, the conventional dyeing method is mainly adopted for dyeing cashmere fibers and products in domestic factories, the dyeing method needs long-time boiling dyeing, the aim is to ensure that scales are opened due to swelling, intercellular substances are more accessible to the dye, and the depth of the dye entering the fibers is determined by the length of the dyeing time and is related to the dyeing fastness. However, the long-term soaking of the cashmere fibers in water at 100 ℃ causes the chemical structure and the physical properties of the cashmere fibers to be changed. First, the cystine bond in the cell structure is broken, and cystine is formed by the linkage of two cysteine molecules through a disulfide bond. This bond may be broken by the increase in water temperature to form a linear polypeptide chain structure. When the temperature exceeds 85 ℃, the hydrolysis speed of peptide bonds is rapidly accelerated, so that the molecular arrangement is changed, and the properties such as dimensional hand feeling, spinnability and the like are changed. Meanwhile, the scale layer is damaged at high temperature, and a cortical layer is exposed on the surface of the fiber, so that the hand feeling is deteriorated, the color and luster are darkened, the strength is reduced, and felting is caused.
The plasma technology is one of new technologies which are being vigorously developed in the 21 st century, and is widely applied to a series of national economy fields such as national defense, industry, agriculture, environment, communication and the like. The plasma is a conductive fluid composed of electrons, ions, atoms (ground state or excited state), molecules (excited state or ground state), radicals, and the like, which are formed by dissociation and ionization of gas molecules by energy excitation such as heating or external electric field and radiation. Macroscopically, their positive and negative charges are equal, and are therefore referred to as a plasma. It is the fourth state of the substance, plasma state, after solid, liquid and gas three states. Plasmas can be divided into high-temperature plasmas and low-temperature plasmas according to the energy and thermodynamic properties of ions forming the plasmas.
The action mechanism of the cold plasma on the surface modification of the high polymer material is that the cold plasma contains a large number of electrons, ions, excited molecules, atoms, radicals, ultraviolet light and other active particles, the energy of the particles is mostly between 0-20 eV, the high polymer material is mostly composed of C, H, O, N four elements, the bond energy between the molecules is mostly between l-10 eV, such as C-H (4.3eV), C-N (2.9eV), C-C (3.4eV), C = C (6.leV) and the like, therefore, when the plasma acts on the surface of the high polymer material through light radiation, neutral molecular flow and ion flow, the plasma active particles completely have enough energy to cause chemical bonds in the polymer to be broken or recombined, and the etching and the chemical modification of the surface of the high polymer material are realized.
In the prior art, the treatment of wool is mostly direct plasma treatment, and a published Chinese patent with the application number of CN202111402124.9 discloses a low-temperature plasma pretreatment process for wool, which comprises the following steps: s1, pre-selection of wool, S2, screening selection, S3, selection treatment and S4, treatment selection. Carry out plasma treatment only to wool in this application, the scale of wool fibre is piled up densely, directly carries out plasma treatment and can make the corruption of wool scale inhomogeneous, leads to the wool to take place local fluff, winding scheduling problem. And the cashmere is easy to deteriorate without subsequent treatment of the cashmere, and has low silkiness, easy felting and difficult dye coloring.
Disclosure of Invention
In view of the above, the invention provides a method for processing cashmere fabric by using low-temperature plasma, which combines the freeze drying and plasma processing technologies, and adopts the low-temperature plasma processing under the atmosphere of oxygen, nitrogen and ammonia gas, so that the scale on the cashmere surface is etched, the coloring capability of the dye is enhanced, and felt is not easy to appear.
The invention relates to a method for treating cashmere fabric by low-temperature plasma, which comprises the following steps;
(1) carrying out vacuum freeze drying on the cashmere fabric to obtain a dried cashmere fabric;
(2) putting the cashmere fabrics after drying the cashmere fabrics into a low-temperature plasma processor, and carrying out low-temperature plasma processing to obtain low-temperature plasma processed cashmere fabrics, wherein the atmosphere of the low-temperature plasma processing is two or three of oxygen, nitrogen and ammonia;
the low-temperature plasma treatment time is 8-10min, and the pressure is 30-35 MPa. Preferably, the plasma treatment gas is a mixed gas of nitrogen and oxygen, and the volume ratio of the nitrogen to the oxygen in the plasma treatment gas is 1: 1; preferably, the plasma treatment gas is a mixed gas of oxygen, nitrogen and ammonia, and the volume ratio of the oxygen, the nitrogen and the ammonia is 5:4: 1.
(3) Carrying out foam coating finishing on the low-temperature plasma treated cashmere fabric, wherein the foam coating finishing comprises the following steps: drying the cashmere fabric treated by the low-temperature plasma at 70 ℃, putting the finishing liquid into a film coating machine, and performing cashmere coating foam finishing to obtain the antistatic cashmere fabric. The finishing liquid comprises cationic modified guar gum, cationic organic silicon modified polyurethane and lauryl betaine (foaming agent), wherein the concentration of the lauryl betaine (foaming agent) is 5.5-6.6 g/L.
The wool fibers are dried just before shrinkage occurs in the vacuum freeze drying in the step (1), and compared with common hot air drying, the vacuum freeze drying can increase the content of amorphous regions of the wool fibers and swell the amorphous regions of the wool fibers, so that the fiber diameter is increased, dyeing is facilitated, and the density of scale structures on the wool fibers is reduced, so that plasma attachment and scale corrosion are facilitated in the plasma treatment process. The scale on the cashmere fiber surface can be opened by increasing the fiber diameter of the cashmere, and the standing scale is beneficial to contacting with plasma when low-temperature plasma treatment is carried out, so that the scale is more thoroughly corroded.
The low-temperature plasma treatment can generate physical etching on the cashmere surface, so that the surface is rough, and the specific surface area is increased. Plasma damages scale layers of cashmere to a certain extent, and simultaneously changes element components on the surfaces of the cashmere, the O/C element ratio of fiber surfaces after plasma treatment is increased, the contents of-C-C-, -S-S-bonds are reduced, the contents of-C-O-, -S-O-bonds are increased, and the changes directly influence various surface properties of the cashmere, improve hydrophobicity and the like.
The gas used in the low-temperature plasma treatment is oxygen, ammonia or nitrogen mixed gas, the scale of the treated cashmere fabric is not complete any more under the nitrogen atmosphere, the edge of the scale is passivated and thinned and can also be raised, and pits and cracks are generated on the surface of the cashmere after the oxygen treatment, so that the etching effect is realized on the cashmere scale, the dyeing process is facilitated in the dyeing stage, and the dyeing time is shortened. The raised cashmere scales after nitrogen treatment are subjected to oxygen treatment, pits, cracks and the like on the scales can enable the scales to be corroded and fall off, and the scale structures of the cashmere fabrics can fall off or are not sharp after plasma treatment, so that the cashmere fabrics cannot shrink due to felting.
After plasma treatment in an ammonia atmosphere, amino sites on the surfaces of cashmere fibers are increased, so that the fuel dyeing effect is improved, and the bacteriostatic ability of cashmere is enhanced.
The C-C, C-H, C-S bonds on the surface of the cashmere fabric are reduced through the treatment of oxygen, nitrogen and ammonia, which is mainly that after plasma treatment, some lipoid on the surface of the cashmere fabric is etched. S-S bonds on the surface of the cashmere are oxidized after being broken to generate SO. Since S-S bonds are hydrophobic and-SO is strongly hydrophilic. Thus, after the plasma treatment, the dye-uptake approaches are obviously increased.
A thin resin layer is formed on the cashmere surface after the foam coating is finished, polymer films with the polymer resin wrapping characteristic can be formed on the fiber surfaces to cover cashmere scales, or the relative slippage of cashmere fibers can be reduced through spot welding to fix the fibers, so that the anti-pilling effect and the antistatic effect of the cashmere are achieved.
According to the invention, the cashmere fabric is subjected to vacuum freezing firstly, so that the diameter of cashmere fibers is increased, the cashmere scales are opened, the cashmere scales are peeled off under the etching action of low-temperature plasma treatment, the surfaces of the cashmere fibers are relatively smoother, and the cashmere fibers have good anti-pilling effect and antistatic capability through foam coating finishing. Oxygen, nitrogen and ammonia are used in the plasma atmosphere, and the surface structures of the cashmere are modified at different angles in the plasma treatment process of various gases, so that the dye of the cashmere is easier to color, and the phenomenon of felting is avoided.
