In a second aspect, the application provides a production process of a novel moisture-absorbing and breathable textile fabric, which comprises the following steps:
I. sizing process
The sectional color yarns and the Sirofil yarns are used as warp yarns, a sectional warping process is carried out at the speed of 50-60m/min, then the warping warp yarns are subjected to a sizing process by adopting sizing agents at the speed of 50-60m/min at the temperature of 40-45 ℃, the sizing rate is controlled to be 7-8%, and then a drafting process is carried out;
weaving Process
Weaving the segment color yarns and the Sirofil yarns at the rotating speed of 620-640r/min in an air jet weaving mode according to the warp density of 322-324 pieces/10 cm and the weft density of 307-313 pieces/10 cm to obtain the fabric;
finishing Process
The fabric is shaped at the temperature of 130-140 ℃ and the vehicle speed of 55-60m/min, desized by desizing enzyme aqueous solution with the concentration of 2-3g/L for 40-45min at the temperature of 80-90 ℃ and the vehicle speed of 50-55m/min, then subjected to softening and tentering by mercerizing smoothing agent aqueous solution with the concentration of 10-12g/L and softening agent aqueous solution with the concentration of 9-11g/L at the temperature of 140-150 ℃ and the vehicle speed of 50-55m/min, the pH of the fabric is adjusted within the range of 4-7.5 by citric acid, and finally preshrinked at the vehicle speed of 50-55m/min to obtain the fabric.
By adopting the technical scheme, the sectional color yarns and the sirofil yarns are taken as the warps, and the sectional warping process is carried out under specific conditions, so that the tensions of all the warps are equal, the warps are uniformly distributed on a warp beam or a loom beam, the processes of sizing, drafting and the like at the later stage are facilitated, and the color arrangement on the warps is in accordance with the process regulations. And then, under a specific condition, sizing is carried out on the warp yarns by adopting the sizing agent, and a layer of thin film is covered on the surface of the warp yarns, so that the strength and the wear resistance of the warp yarns are improved.
This application strict control starching process's temperature adopts the mode of low temperature starching in specific within range, because the fibrous dissolving temperature of water-soluble PVA that this application adopted is about 85 ℃, consequently controls starching process's temperature, has reduced the PVA fibre and has just taken place the possibility of dissolving at the starching process, if the PVA fibre just takes place to dissolve at the starching process, then can make the yarn thin, the later stage weaving process difficulty. Simultaneously, because at the starching in-process, the yarn takes place the adhesion easily, therefore the speed of this application control starching is in specific within range, has reduced the later stage to the warp and has separated into the possibility that the plastic film is torn when two-layer upper and lower. And, because the thick liquids dissolve the back to PVA fibre, the PVA fibre that dissolves can remain in the inside of yarn, can bond with other fibre in the yarn together after drying, consequently this application control sizing percentage is in specific scope for the thick liquids cover on the warp can, need not soak the warp completely, reduced the use amount of thick liquids, reduced manufacturing cost.
And (3) carrying out beating-up weaving on the warp yarns subjected to the sizing process in an air jet weaving mode under the condition of specific rotating speed. Because PVA fiber takes place to dissolve at later stage desizing process and makes the yarn count of warp and woof attenuate, the density of surface fabric becomes thin, and the degree of tightness of fabric can reduce, consequently this application control warp direction density and latitudinal direction density are in specific within range for the initial degree of tightness of fabric is higher, has reduced along with PVA fiber's dissolution, and the degree of tightness of fabric descends too big and makes the position of warp and woof take place to remove and the possibility that appears broken hole fault. However, if the initial tightness of the fabric is too high, the resistance of the beating-up process is increased, and the difficulty of the weaving process is increased.
Because the fabric contains a large amount of water-soluble PVA fibers and nylon fibers, the woven fabric is firstly subjected to a shaping process under specific conditions, so that the shape structure of the nylon fibers in the fabric is shaped, and after the water-soluble PVA fibers are dissolved in the later desizing process, the fibers in the fabric can also be in a spiral shape, so that the prepared fabric is more fluffy and has higher comfort.
After shaping, desizing is carried out on the fabric under a specific temperature condition, PVA fibers in the fabric are dissolved by water in desizing enzyme within a specific temperature range, other fibers in the fabric are loosened, and the density of the fabric is thinned, so that the air permeability of the fabric is enhanced. And then, a specific amount of mercerizing smoothing agent and softening agent is used for carrying out a softening and tentering process on the fabric under specific conditions, so that the softness of the fabric is improved, the comfort of the fabric is improved, the pH value of the prepared fabric is controlled in a better range, and the pH value of the fabric is too high or too low due to the weak acidity of the skin of a human body, so that the skin of the human body is stimulated, and the comfort of the fabric is reduced. And then the fabric is preshrunk, so that most of potential shrinkage stress in the fabric is fully eliminated, and the shrinkage rate of the fabric is reduced, so that the prepared fabric meets the standard requirement.
Preferably, in the step I, the slurry comprises the following components in percentage by weight: 25-27% of PVA slurry, 60-62% of modified starch, 7.5-8.5% of polyacrylic acid and the balance of polymethyl acrylate.
By adopting the technical scheme, the modified starch has excellent adhesion to tencel fibers, can be well attached to the surface of the fibers, then improves the elongation at break of the size film through PVA powder, reduces the possibility of occurrence of brittle fracture in the weaving process, and simultaneously, because the mortar coverage is higher, the yarns are easy to adhere to each other, so that polyacrylic acid and polymethyl acrylate with specific proportion are used to be added into the size film, the resistance met by warps when the warps are divided into an upper layer and a lower layer can be reduced, and the possibility of tearing the size film is reduced.
Therefore, PVA powder, modified starch, polyacrylic acid and polymethyl acrylate in a specific proportion range are mixed and matched to be used as slurry, the synergistic effect among the PVA powder, the modified starch, the polyacrylic acid and the polymethyl acrylate can be fully exerted, the strength of the yarn is increased, a layer of film with high breaking elongation is formed on the surface of the yarn, and the wear resistance of the fabric is improved.

Performance detection
Detection 1: the air permeability (mm/s) of the fabrics of examples 1-3 and comparative examples 1-3 was tested with reference to GB/T5453-1997 determination of air permeability of textile fabrics;
and (3) detection 2: reference GB/T20944.2-2007 evaluation of antibacterial properties of textiles-part 2: the absorption method detects the bacteriostasis rate (%) of the fabrics of the examples 1-3 and the comparative examples 1-3;
and (3) detection: reference GB/T3923.1-2013 part 1 of tensile Properties of textile fabrics: determination of breaking strength and breaking elongation (bar method) the fabrics of examples 1 to 3 and comparative examples 1 to 3 were tested for breaking elongation (%);
the results of the above tests 1 to 3 are shown in Table 1.
Table 1 table of performance test results
Figure GDA0003314314330000151
Figure GDA0003314314330000161
As can be seen from Table 1, the air permeability of the fabric prepared by the examples 1-3 is 49.5-55.2%, the antibacterial rate is 97.3-99.1%, which is far higher than the standard requirement, and the elongation at break is 150.6-152.6, which indicates that the fabric prepared by the examples 1-3 has higher moisture absorption and air permeability, antibacterial performance and strength.
Although the air permeability of the comparative example 1 is higher than that of the example 2, the elongation at break of the comparative example 1 is obviously lower than that of the example 2, which shows that when the warp density and the weft density are lower, the density of the fabric becomes more sparse after the PVA fibers are dissolved, so that the moisture absorption and air permeability performance is improved, but the quality of the fabric is poor because the distance between the fibers is too large and too loose, and the strength of the fabric is reduced to a large extent.
The air permeability, the bacteriostasis rate and the elongation at break of the comparative example 2 are lower than those of the example 2, which shows that when the warp density and the weft density are too high, the PVA fibers can not be dissolved in the desizing process, so that the fabric cannot be thinned, and the moisture absorption and air permeability of the fabric are reduced.
The air permeability, the antibacterial rate and the elongation at break of the comparative example 3 are lower than those of the example 2, which shows that the fabric is desized and then shaped, so that other fibers in the fabric are not shaped and the PVA fiber is dissolved, and other fibers in the fabric can not keep a fluffy structure, so that the moisture absorption, the air permeability and the strength of the fabric are reduced, and the comfort of the fabric is further reduced.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
