Description
Technical Field
The invention relates to the technical field of textile, in particular to a soft and moisture-absorbing coral fleece fabric and a preparation method thereof.
Background
The consumption concept of the textile is always changed along with the development of economy and society, and the traditional saturated life concept is changed into the current good-wearing life concept, and the rapid development of the times is reflected, so that the living standard of people is rich. The modern society at present improves the living standard, and people have higher requirements on the functionality, comfort, fashion and the like of textiles, and pay more attention to whether the fabric has the characteristics of safety, environmental protection, moisture absorption, sweat release, comfort, skin friendliness and the like. According to the requirements, various modes for improving the performance of the fabric are layered endlessly, and fiber blending, yarn and fabric structural design, post-treatment processing modes and the like are adopted. In cold winter, it is desirable to wear warm-keeping comfortable but non-bulky garments, wherein raised coral fleece fabrics can improve the warm-keeping effect of the fabric. The fabric forms fluff on the surface of the fabric in a special treatment mode, the standing air between the fluff has good warm-keeping effect, the fabric style is specific, the aesthetic requirement of people is met, and part of night gown, blanket and bath towel which are frequently used at ordinary times are also coral fleece fabrics.
The coral fleece fabric has rich fabric styles, and the surface of the fabric has coral fleece characteristics. The coral fleece is usually made of thinner monofilament fibers, and the initial modulus of the fleece is low and the hand feeling is softer. The fluff on the surface of the fabric has large specific surface area and high density, so that the fabric has good coverage, high air permeability and high water conductivity, and the fluff layer can be fully attached to a wiped object due to the softness of the fluff, so that the cleaning effect is excellent, and the warm hand feeling is given to the fabric by the air existing between the fluff. However, coral fleece is easy to generate static electricity due to friction between fleece, and phenomena such as fleece falling and the like can be caused by weaving process and material selection, so that normal wearing performance is affected, and a large improvement space is provided for the softness and hygroscopicity of fleece.
Different types of fibrous materials have different effects on the comfort of coral fleece. The natural fiber takes cotton as an example, the prepared coral fleece fabric has good moisture absorption performance, but cotton fiber fleece can lodge and wrinkle due to moisture absorption expansion; because cotton fiber has lower strength and circular cross section and natural curl, the wool is easy to fall off in the wearing process. The synthetic fiber takes common terylene as an example, the coral fleece fabric has good shape retention, high fiber strength and poor hygroscopicity, is difficult to fall Mao Qizhou, is easy to generate static electricity, is easy to tangle and suck ash, has rough hand feeling and is easy to generate stuffiness. At present, the common practice aiming at the defects is to blend natural fibers with chemical fibers, reasonably control the functional expression of various fibers and achieve the aim of improving comfort. However, the method can lose the dominant performance of the fiber and increase the processing difficulty of the fabric, so that research on improving the comprehensive performance of the coral fleece fabric is still to be further broken through.
In order to improve the moisture absorption performance of the coral fleece fabric, CN112410978A discloses a preparation method of a high-hydroscopicity double-sided printed polyester-nylon coral fleece fabric. The white grey cloth is subjected to processes such as sewing, primary pre-shaping treatment, fiber opening treatment, secondary tentering shaping treatment, high-temperature fixation, fluffing and carding, tertiary shaping treatment and the like, and the super-absorbent double-sided printing polyester and nylon coral fleece fabric is prepared. The preparation method provided by the invention is simple in process and low in cost, and the prepared polyester-nylon coral velvet fabric not only can keep the excellent quality of the polyester-nylon and coral velvet fabric, but also can keep good water absorbability when the fabric is subjected to double-sided printing treatment. However, the method has a certain destructive effect on the fiber structure, so that the coral fleece fabric is easy to fall off in the use process, and the prepared velvet has a harder hand feeling.
The publication number CN111118626A relates to a preparation method of coral fleece fabric, which adopts profiled semi-dull polyester drawn yarns as raw materials of wool yarns, and comprises the following preparation processes: and extruding the PET melt from a trilobal spinneret hole on a spinneret plate, and then adopting circular blowing and cooling, wherein three leaves of the trilobal spinneret hole are equal in length and unequal in width, are distributed in concentric circles, and the center line of the narrowest leaf passes through the center of the circle and points away from the center of the circle. Knitting and weaving polyester FDY yarns serving as a base yarn raw material to obtain a wool grey fabric, and performing pre-setting, soft finishing, wool opening, napping and napping, post-finishing and re-shaping to obtain a coral fleece fabric; the preparation method is simple to operate, and the prepared coral fleece fabric has fluffy and plump velvet, soft hand feeling and good warmth retention property. However, the method mainly starts from the cross-section form of the polyester fiber, and the prepared coral fleece fabric has poor moisture absorption performance.
The publication No. CN103395235A discloses a windproof moisture-permeable coral fleece fabric and a production method thereof, wherein a microporous windproof moisture-permeable film and a single-brush single-shake fabric are sequentially attached to the coral fleece fabric through glue; the single-brush single-shake fabric is formed by weft knitting of plain stitch loops and terry stitch loops with elongated sinker loops, the number of warp-wise polyester yarns in the single-brush single-shake fabric is 21, and the number of weft-wise polyester yarns is 23; the raw materials of the plain stitch and the terry stitch are polyester yarns, the polyester yarn specification of the plain stitch is 75D/36F, and the polyester yarn specification of the terry stitch is 75D/72F. The coral fleece fabric has the effects of wind prevention and outward discharge of moisture in clothes. However, the glue adopted by the fabric has the defects of environmental protection and poor air permeability and stability.

The fabric prepared from the polyester fiber is commonly used in the textile field, particularly the clothing field, due to the advantages of high mechanical strength, high chemical resistance, good crease resistance, good dimensional stability, low cost and the like, however, the polyester fiber has the advantages of limited hydrophilicity, low moisture regain, high fiber rigidity, strong itching feeling when being worn and poor ultraviolet radiation protection capability. Therefore, the modification of the differential function of the polyester fiber is an important research direction, and the general environmental protection method for enhancing the hydrophilic performance is to graft the protein extracted from animals and plants onto the surface of the polyester fabric through a chemical crosslinking agent so as to improve the hydrophilic property of the surface of the polyester fabric. Although these methods provide a great improvement in the properties of polyester fibers and fabrics, certain protein materials are expensive and crosslinking agents are not environmentally friendly materials and can be harmful to the environment and skin. Thus, obtaining natural proteins from environmentally friendly biopolymers remains a great challenge.
For polyester fibers with high rigidity, softeners on the global market generally have special chemical structures and mainly comprise two long hydrophobic alkyl chains. Thus, the surface of yarns and fabrics treated with softeners consisting of cationic surfactants and branched alkyl anionic surfactants can easily become hydrophobic, and this type of softener is effective in improving the water absorbency of fabrics. For example, imidazole salt softeners are synthesized from low cost materials such as fatty acids and diethylenetriamine, and act on textiles to give a soft feel, but inhibit the creation of a network of bound water mediated between fibers through hydrogen bonding, reducing the water absorption properties of textiles.
In order to reduce the rigidity of the polyester fiber and impart good moisture absorption properties, a raised structure is constructed by introducing small hydrophilic particles on the surface of the polyester fiber, thereby adding a new hydrophilic surface. The hydrophilic particles are obtained by copolymerizing vinyl acetate and cationic starch, wherein the prepared hydrophilic particles do not keep the original round shape on the surface of the polyester fiber, but are adhered to the polyester fiber by water plasticization due to the low glass transition temperature of the vinyl acetate, and the polyester fiber is firmly wrapped by the highly hydrophilic particles to form a convex structure, so that the hydrophilic particles have better softness on the polyester fiber and can be grafted with hydrophilic groups, and the moisture absorption performance of the fabric is endowed.
Cowpea is kidney-shaped small seed belonging to leguminous plants. Cowpea contains abundant proteins, bioactive compounds and antioxidative active flavonoids. The cowpea contains different amino acids, so that long-chain molecules can be generated, and the amino groups can be combined with cowpea proteins to generate the active polymer for improving the moisture absorption and ultraviolet resistance of the fabric. Therefore, the modified cowpea protein and the modified starch can be grafted to the surface of the polyester coral fleece fabric in a polymerization grafting mode, so that the flexibility, the hygroscopicity and the ultraviolet protection level of the polyester coral fleece fabric are enhanced. Firstly, pretreating polyester coral fleece fabric by using nitric acid solution to enable the polyester coral fleece fabric to be attached with nitro, and then reducing the polyester coral fleece fabric into amino; then, the epoxy resin and epichlorohydrin undergo substitution reaction in alkaline medium to synthesize the cross-linking agent. The amino acids of cowpea proteins are zwitterionic under neutral conditions, with both negative and positive carboxyl groups. Oxygen in cowpea protein and a cross-linking agent are substituted and solidified under alkaline conditions; then combining the modified cowpea protein and the modified starch polymer with the amino groups on the pretreated polyester coral fleece fabric, and grafting the modified cowpea protein and the modified starch polymer on the pretreated polyester coral fleece fabric. And forming a hydrophilic cross-linked network on the surface of the polyester coral fleece fabric. The polyester coral fleece fabric has the advantages of softness, hygroscopicity and ultraviolet resistance.
Due to the adoption of the technical scheme, compared with the prior art, the preparation method of the soft and moisture-absorbing coral fleece fabric has the advantages that: 1) The coral fleece fabric prepared from the polyester filaments has the characteristics of difficult wrinkling, washability, no hair falling and good finishing. 2) The starch and the cowpea protein are grafted to the coral velvet fabric by adopting a specific grafting method, so that the characteristics of softness, moisture absorption and ultraviolet resistance of the coral velvet fabric are endowed, and the excellent wearing comfort of the fabric is enhanced, 3) the natural high molecular compound is grafted to the coral velvet fabric in a chemical bond mode, the fabric has stronger durability in softness, moisture absorption and ultraviolet resistance, and the material is environment-friendly.

Test example 1
Itching feel test: according to the test method of the Shuoshi paper (study for improving the itching feeling of ramie fabric, author: tian, university of east China, 2013), the compression performance of the pile on the surface of the sample fabric was measured by a compression instrument.
The pressure of the pile on the surface of the sample at the end of the compression stage represents the boundary pressure, the length, the number and the rigidity of the pile are all important factors influencing the boundary pressure, the compression ratio work represents the work consumed by unit compression displacement, and the boundary pressure (cN) and the compression ratio work (cN) of the pile on the surface of the sample during compression are important observation indexes for judging the itching feeling and the flexibility. The length and the number of the plush in the sample are almost the same, so that the test index can directly reflect the rigidity of the plush and further reflect the flexibility of the coral fleece fabric. The test results are shown in Table 1.
The calculation formula between the itching value (five-point score) and the demarcation pressure is: itching value = -1.908+4.008 x demarcation pressure (cN).
Sample: the length and width of the test sample are 20cm multiplied by 8cm, three test pieces are taken for each sample, and the average value is taken.
Table 1: test results of itching feeling of test sample
As can be seen from the test results of the itching feeling of the test sample, the itching feeling value of the example 1 added with starch, vinyl acetate and cowpea protein is the lowest, which shows that the plush rigidity is the lowest, the fabric flexibility is the best, and the possible reasons are that the copolymerization of vinyl acetate and starch enhances the flexibility of the fiber, and the raised structure is constructed on the surface of the polyester fiber, which is beneficial to the grafting of the hydrophilic group of the modified cowpea protein, the polyester fiber is firmly wrapped by the highly hydrophilic particles to form the raised structure, and the raised structure has better softness function on the polyester fiber, and simultaneously grafts the hydrophilic group, thereby endowing the coral fleece fabric with flexibility and moisture absorption performance; on the other hand, the fiber has larger moisture absorption capacity, the moisture regain of the coral fleece fabric is higher, and the bending rigidity of the polyester fiber is further reduced, so that the flexibility of the ungrafted modified cowpea protein coral fleece fabric in the embodiment 4 is slightly poorer than that in the embodiment 1, the fiber rigidity is slightly higher, and the itching feeling is slightly higher.
Test example 2
And (3) testing the moisture absorption performance of the fabric: since the moisture absorption capacity of textile materials varies in different states, fabrics are generally characterized by moisture content.
Test instrument: y802 eight basket oven with constant temperature.
Test standard: for the test of the moisture absorption performance of coral fleece fabrics, reference is made to GB/T9995-1997 determination of moisture content and moisture regain of textile materials-oven drying method, and pre-conditioning is carried out for 24 hours under the environmental conditions of 20+ -2deg.C and relative humidity of 65+ -2%, 3 experiments are carried out for each sample, and finally the average value of 3 experiments is taken, and the test data are shown in Table 2.
The calculation formula of the moisture regain is as follows:
W＝(G-G0)/G0×100％
wherein: w-moisture regain/%;
g-sample water weight/G;
g0-sample dry weight/G.
Table 2: moisture absorption performance test result of fabric
| Experimental protocol | Moisture regain/% |
| Example 1 | 9.29 |
| Example 2 | 8.91 |
| Example 3 | 7.31 |
| Example 4 | 6.22 |
| Comparative example 1 | 5.60 |
The fabric moisture absorption test result shows that the moisture regain is highest in the example 1 with starch, vinyl acetate and cowpea protein added, and the main reason is that the vinyl acetate and starch are copolymerized and grafted with partial hydrophilic groups, and the structured raised structure provides new grafting sites, so that the modified cowpea protein is favorably grafted onto the fiber, a large number of hydrophilic groups are grafted onto the surface of the fiber, the moisture absorption performance of the fabric is enhanced, and the wearing comfort is improved.
Test example 3
And (3) testing the anti-hair falling performance: the wool on the surface of the coral fleece fabric can fall off to a certain extent after friction, refer to part 1 of the measurement of the pilling Property of textile fabrics of GB/T4802.1-2008: the abrasion resistance is used for representing the wool drop rate of the fabrics according to the test of the circular locus method. The same friction conditions and friction times are controlled on the surface of the coral fleece fabric, the mass of the sample before and after friction is weighed, the anti-fleece performance of the sample is measured by the mass loss rate after friction, and the smaller the mass loss rate of the sample is, the better the fleece anti-fleece performance is.
Test instrument: YG522N fabric abrasion resistance tester.
The experimental method comprises the following steps: 10 circular rings (with the diameter of 125 mm) are respectively cut for each sample to be used as a test, a small hole is cut in the middle of the sample, and the dehairing rate test is carried out under the standard atmospheric condition by adopting a rotary flat grinding method. After 400 times of friction, the mass loss rate, i.e. the hair loss rate, of each sample was calculated according to the following formula, and the test results were as follows.
V＝(W-W0)/W0×100％
Wherein: V-Mass loss Rate/%;
w-mass/g before fabric abrasion;
w0-mass/g after abrasion of the fabric.
The mass loss rate of the anti-hair-falling performance test of the soft and moisture-absorbing coral fleece fabric prepared by the invention is below 2.5%, which indicates that the soft and moisture-absorbing coral fleece fabric has better anti-hair-falling performance.
