Comparative examples 1 to 7
Comparative examples 1 to 7 respectively provide a preparation method of a fabric. Compared with the embodiment 1, the difference of the comparative examples 1 to 4 is that only one polyester master batch is used to prepare the polyester yarn with single component for carrying out interlock weaving; the yarns used in comparative examples 1-4 are shown in Table 2.
TABLE 2 yarns and fabric constructions used in comparative examples 1-4
| Item | Yarn | Fabric structure |
| Comparative example 1 | Conventional polyester yarn on the market | Double rib |
| Comparative example 2 | Hollow conventional polyester yarn | Double rib |
| Comparative example 3 | Commercially available hydrophilic polyester yarn | Double rib |
| Comparative example 4 | Hollow hydrophilic polyester yarn | Double rib |
Comparative example 5 differs from example 1 in that the two yarns used are a commercially available hollow conventional polyester yarn and a commercially available hollow hydrophilic polyester yarn, respectively.
Comparative example 6 is different from example 1 in that the weaving method is used, and comparative example 6 is woven in a plain weave method using the hollow conventional polyester yarn and the hollow hydrophilic polyester yarn obtained in example 1 as the warp and the weft, respectively.
The difference of comparative example 7 from example 1 is that, in step S2, the dried conventional polyester masterbatch and the hydrophilic polyester masterbatch are blended and then melt-spun to obtain a hollow composite polyester yarn.
The fabric prepared in the embodiment 1 and the comparative examples 1-7 is tested for moisture permeability, air permeability and heat preservation rate, wherein the moisture permeability test conditions are as follows: temperature 38 deg.C, humidity 50% RH; the test conditions for air permeability were: the sample difference is 100Pa, the caliber is 16cm, and the test area is 20cm2(ii) a The results are shown in Table 3.
TABLE 3 Performance parameters of the fabrics prepared in example 1 and comparative examples 1-7
As can be seen from table 3, the combination of properties of the hollow polyester fiber-based bicomponent thermo-wet comfort fabric prepared in example 1 is superior to the other respective proportions. Compared with the examples 1 and 1-4, the fabric prepared from the polyester yarns with the hollow structures has better moisture permeability, air permeability and heat preservation rate than the fabric prepared from the polyester yarns without the hollow structures; the fabric prepared from the hydrophilic polyester yarns has better moisture permeability than the fabric prepared from the conventional polyester yarns, but the air permeability and the heat preservation performance of the fabric are not as good as those of the fabric prepared from the conventional polyester yarns. In the embodiment 1, the hollow conventional polyester yarn and the hollow hydrophilic polyester yarn are woven together, so that the problems of poor moisture permeability or poor heat retention and poor air permeability caused by singly using the hollow conventional polyester yarn or singly using the hollow hydrophilic polyester yarn can be effectively solved, and the prepared fabric has excellent moisture permeability, air permeability and heat retention.
Comparing example 1 with comparative example 5, it can be seen that the moisture permeability, air permeability and heat preservation rate of the bi-component thermo-moisture comfort fabric based on the hollow polyester fiber prepared in example 1 are obviously superior to the fabric performance of the commercially available hollow conventional polyester and the commercially available hollow hydrophilic polyester yarn, which indicates that the hollow polyester fiber prepared by the method provided by the invention is superior to the corresponding commercially available fiber, and the prepared fabric has more excellent moisture permeability, air permeability and heat retention.
Comparing example 1 with comparative example 6, it can be seen that although the bi-component thermo-moisture comfort fabric based on hollow polyester fiber prepared in example 1 has slightly lower moisture permeability and air permeability than the plain woven fabric, the thermal insulation is much higher than the plain woven fabric, and the overall performance of the interlock fabric is better in combination. Therefore, the bi-component thermal-wet comfort fabric based on the hollow polyester fibers prepared by adopting the interlock weave method has the comprehensive performance superior to that of the conventional plain weave fabric.
It can be seen from the comparison between example 1 and comparative example 7 that the moisture permeability, air permeability and thermal insulation rate of the fabric woven by the hollow composite polyester yarn prepared by blending two polyesters are all lower than those of the hollow polyester fiber-based bi-component thermal-humidity comfortable fabric prepared in example 1, mainly because the two polyesters are easily affected with each other after being directly blended, and the advantages of each component cannot be fully exerted. According to the invention, two types of polyester are respectively made into two types of yarns and then are subjected to interlock weaving, so that the two types of materials are independent from each other, the advantages of the two types of materials are kept, the two types of materials are tightly combined, the composite effect is achieved, and the prepared fabric has more excellent comprehensive performance.
Examples 2 to 3
Examples 2 to 3 respectively provide a method for preparing a bi-component thermal-wet comfortable fabric based on hollow polyester fibers, compared with example 1, the method is different in that the melt spinning parameters in step S2, including the temperature of each section of the single-screw extruder, the spinning temperature and the winding speed, are changed, and thus the linear densities of the hollow conventional polyester yarn and the hollow hydrophilic polyester yarn prepared in step S3 are changed, and the specific parameter values corresponding to each example are shown in table 4.
TABLE 4 melt spinning parameters for examples 2 to 3
The moisture permeability, air permeability and heat preservation rate of the hollow polyester fiber-based bi-component heat and humidity comfort fabric prepared in examples 2-3 were measured, and the results are shown in table 5.
TABLE 5 Performance parameters of fabrics made in examples 2-3
As can be seen from Table 5, as compared with example 1, the moisture permeability and air permeability of the resulting hollow polyester fiber-based bicomponent thermo-moisture comfort fabric gradually increased with the increase in the melting temperature and winding speed of each stage of the single screw machine, while the heat retention rate decreased. Mainly due to the fact thatWhen the melting temperature and the winding speed are increased within a certain range, the linear density of the yarn is decreased due to the change in the fiber diameter, and the moisture permeability and air permeability of the fabric woven from the yarn are enhanced, but the heat retention rate is decreased. Therefore, in order to achieve comprehensive and excellent performance of the fabric, technological parameters such as melting temperature, winding speed, linear density and the like need to be controlled, the temperature range of the screw extruder is preferably 235-270 ℃, the spinning temperature is 260-270 ℃, the winding speed is 2800-3500 m/min, and the linear density of the yarn is 15-25 tex. The bi-component heat-moisture comfortable fabric based on the hollow polyester fiber prepared under the condition can simultaneously have excellent moisture permeability, air permeability and heat retention, and the moisture permeability is more than 3200g/m2D, the air permeability is more than 6500mm/s, and the heat preservation rate is more than 16%.
In conclusion, the conventional polyester yarn with the hollow structure and the hydrophilic polyester yarn with the hollow structure are prepared and woven by adopting the interlock weave method, so that the fabric has excellent moisture permeability, air permeability and heat retention by utilizing the difference of the hydrophilic properties of the two yarns; and the air permeability and the heat retention of the fabric can be improved by utilizing the hollow structure of the yarn, and the stability and the heat retention of the interlock weave method are combined, so that the prepared double-component heat-moisture comfortable fabric based on the hollow polyester fiber has higher comfort. Meanwhile, the preparation method of the hollow polyester fiber-based bi-component heat-moisture comfortable fabric is simple and easy to implement, can meet the requirement of large-scale production, and has a good application prospect.
