[0025] The utility model is further explained in connection with the drawings and specific embodiments.

[0026] In connection with Figures 1-5 The one-way wet guide fabric of the utility model includes the surface layer 1, the inner layer 2 and the single-layer double-face weft knitting organization part 3 connected with the surface layer 1 and the inner layer 2 formed by the yarn with the minimum cycle unit circular knitting, and the single-layer double-face weft knitting organization part 3 makes the surface layer 1 and the inner layer 2 form the through horizontal cavity 5 and the vertical cavity 4. The minimum cycle unit includes: the surface layer plain stitch 11 of the surface layer 1 formed by the under needle loop formation knitting, the inner layer plain stitch 21 of the inner layer formed by the over needle loop formation knitting, and the single-layer double-face weft knitting organization 31 of the single-layer double-face weft knitting organization part 3 formed by the over needle spacing needle loop formation and the under needle partial needle continuous loop formation knitting, and the single-layer double-face weft knitting organization 31 is connected with the surface layer plain stitch 11 and the inner layer plain stitch 21 respectively.

[0027] The utility model discloses a unique single -layer double -sided weft -knitting organization 3 connects inner layer 2 and surface layer 1, forms the transverse and longitudinal cavity network of cross -through, and single -layer double -sided weft -knitting organization 31 reduces yarn consumption through the design of the loop of upper needle spacing needle and the loop of lower needle partial needle continuous, makes fabric have light and thin characteristics and structural stability, thereby reduce fabric gram weight.

[0028] In some embodiments of the utility model, single -layer double -sided weft -knitting organization 31 includes several first knitting ways and second knitting ways of phase interval configuration. First knitting way and second knitting way are all configured as the loop of upper needle spacing needle and have at least the loop of lower needle continuous three needles, and the loop position of first knitting way and second knitting way is complementary. Surface layer plain knitting organization 11 includes several third knitting ways of the loop of lower needle all, and inner layer plain knitting organization 21 includes several fourth knitting ways of the loop of upper needle all, and the third knitting way and fourth knitting way are phase interval configuration. The number of each knitting way and its specific loop number can be adjusted according to actual needs.

[0029] In some embodiments of the utility model, inner layer plain knitting organization 21 is knitted by hydrophobic moisture -conducting yarn, and one of surface layer plain knitting organization 11 and single -layer double -sided weft -knitting organization 31 is knitted by elastic yarn, and the other is knitted by inelastic yarn or moisture -absorbing and sweat -releasing yarn. The utility model adopts different knitting process, surface layer plain knitting organization 11 ensures fast moisture absorption, inner layer plain knitting organization 21 realizes effective sweat -releasing, and single -layer double -sided weft -knitting organization 31 reduces yarn usage through the design of the loop of upper needle spacing needle and the loop of lower needle partial needle, which significantly reduces the gram weight of fabric while maintaining good moisture -conducting performance.

[0030] The hydrophobic moisture -conducting yarn is preferably propylene yarn, the elastic yarn is preferably polyester high -elastic yarn or PBT / PET composite elastic yarn, the moisture -absorbing and sweat -releasing yarn is preferably moisture -absorbing and sweat -releasing polyester yarn, and the inelastic yarn is preferably inelastic polyester yarn, so as to improve the one -way moisture -conducting performance or mechanical performance of fabric.

[0031] In order to further reduce the gram weight of fabric, the specification of PBT / PET composite elastic yarn is preferably 30D-50D / 36F, the specification of moisture -absorbing and sweat -releasing polyester yarn is preferably 30D-50D / 36F, the specification of propylene yarn is preferably 35D-50D / 48F, the specification of polyester high -elastic yarn is preferably 45D-50D / 36F, and the specification of inelastic polyester yarn is preferably 30D-50D / 36F. By selecting different specifications of yarn to knit one -way moisture -conducting fabric, the finished product gram weight is 90-126g / m 2 .

[0032] In some embodiments of the utility model, the yarn weight ratio of hydrophobic moisture -conducting yarn, elastic yarn, inelastic yarn / moisture -absorbing and sweat -releasing yarn is 40%-47%:11%-27%:33%-42%. The matching scheme makes the fabric reduce the gram weight while ensuring the one -way moisture -conducting performance and the stability of structure.

[0033] Polypropylene yarn is a kind of light, high-strength synthetic fiber, which has good wear resistance and elasticity. The moisture absorption of polypropylene yarn is very small, almost no moisture absorption, and the moisture regain under general atmospheric conditions is close to zero, but it has wicking effect, can transmit water vapor through the capillary in the fiber, and itself does not have any absorption effect, and its fiber characteristics help to realize the one-way moisture transfer function. In addition, polypropylene yarn also has good physical antibacterial and physical ultraviolet resistance.

[0034] PBT / PET composite elastic yarn is a functional fiber spun by PBT (polybutylene terephthalate) and PET (polyethylene terephthalate) through parallel composite spinning technology. The shrinkage difference of the two polyester components on the fiber cross section will produce different degrees of shrinkage after wet heat treatment, so that the fiber presents a permanent three-dimensional spiral curl structure, giving the yarn excellent elastic recovery (the recovery rate is 30%-40% higher than ordinary polyester) and durability. The yarn fiber cross section is in the shape of an eight, and the moisture absorption and quick drying performance is outstanding (the quick drying performance is 8 times higher than cotton, and the moisture absorption is 2 times higher than ordinary polyester).

[0035] Moisture absorption and sweat release yarn is a kind of functional yarn, which is usually spun by using special-shaped spinneret plate, and the fiber cross section is non-circular, such as Y-shaped, cross-shaped, W-shaped and bone-shaped. Moisture absorption and sweat release yarn uses fiber cross section shaping to form grooves on the fiber surface, which can quickly absorb sweat and diffuse along a specific direction (such as from the inner layer to the surface) through capillary effect, and accelerate evaporation. The special-shaped fiber cross section increases the fiber surface area and the number of fiber contact points, forming a mechanical interlocking effect, which can effectively prevent hair from sliding out of the fabric surface, enhance the fiber interlocking force and surface friction resistance, and improve the anti-pilling performance. The moisture absorption and sweat release polyester yarn in the moisture absorption and sweat release yarn has excellent moisture absorption and quick drying properties.

[0036] PBT / PET composite elastic yarn, moisture absorption and sweat release polyester yarn and polypropylene yarn are preferably selected to weave the one-way moisture transfer fabric of the utility model with the smallest cycle unit, so as to reduce the grammage while improving the anti-pilling performance of the fabric, realizing the synergistic improvement of light weight and durability. Specifically as follows:

[0037] Firstly, the capillary effect of the cross-sectional structure of the PBT / PET composite elastic yarn and the moisture-wicking polyester yarn can enhance the moisture-wicking efficiency, the dense hydrophobic network formed by the polypropylene yarn in the inner layer 2 can quickly conduct sweat from the skin side to the outside of the fabric, realize the one-way moisture-wicking function, and the one-way sweat index can reach level 5 after 150 washes, which can continuously maintain high one-way moisture-wicking performance and provide a dry and comfortable wearing experience for the human body. Secondly, the low denier yarn combination and the lightweight characteristics of the polypropylene yarn reduce the fabric weight, making the fabric more lightweight and breathable, thereby improving the wearing comfort. Thirdly, the cooperation of the organizational structure and the yarn makes the fabric surface more flat and tight, reduces the friction and hooking between fibers, effectively improves the anti-hooking and anti-pilling ability of the fabric, and the anti-pilling can reach level 4 and the anti-hooking can reach level 2-3. Fourthly, the polypropylene yarn also endows the fabric with good physical antibacterial and physical anti-ultraviolet properties. After detection, the fabric can achieve 7a level antibacterial effect and natural anti-ultraviolet effect, and the physical heat shielding effect is more than 40%.

[0038] In other embodiments of the present application, the inner layer flat knitting structure 21 is knitted by hydrophobic moisture-wicking yarn and conductive yarn. The hydrophobic moisture-wicking yarn and conductive yarn can be selected and knitted in the inner layer flat knitting structure 21, or the hydrophobic moisture-wicking yarn and conductive yarn can be knitted in each route.

[0039] The conductive yarn is a kind of conductive fiber made of silver-plated fiber and ordinary fiber, which can eliminate charge accumulation through static discharge or corona discharge. In the one-way moisture-wicking fabric of the present application, the addition of conductive yarn can prevent static electricity and improve the wearability of the fabric.

[0040] Embodiment one

[0041] Figure 4 The knitting diagram of the one-way moisture-wicking fabric of a preferred embodiment of the present application has 21 routes, each of which is knitted by 14 upper needles and 12 lower needles. The needle arrangement of the upper needle and the lower needle is ribbing opposite needle, and the triangular configuration diagram is as shown in Figure 5 , wherein the needle arrangement sequence of the dial is 12121212121212, the needle arrangement sequence of the needle cylinder is 212121212333, and "∨" and "∧" represent looping, and "-" represents non-knitting. The 21 routes are specifically:

[0042] The first and third routes are the first knitting route, the odd-numbered upper needles do not participate in knitting, and the even-numbered upper needles are all knitted into loops, the first-9 lower needles do not knit, and the 10-12 lower needles are all knitted into loops;

[0043] The 2nd and 4th routes are second knitting routes, the odd-numbered needles are knitted into loops and the even-numbered needles are not knitted, the 1st-9th lower needles are not knitted and the 10th-12th lower needles are knitted into loops;

[0044] The 5th, 7th, 9th, 11th, 13th, 15th, 17th, 19th and 21st routes are third knitting routes, the upper needles are not knitted and the lower needles are all loops;

[0045] The 6th, 8th, 10th, 12th, 14th, 16th, 18th and 20th routes are fourth knitting routes, the upper needles are all loops and the lower needles are not knitted.

[0046] Among them, the 1st-4th routes form a single-layer double-sided weft knitting structure 31, the 5th, 7th, 9th, 11th, 13th, 15th, 17th, 19th and 21st routes form a surface flat knitting structure 11, and the 6th, 8th, 10th, 12th, 14th, 16th, 18th and 20th routes form a back flat knitting structure 21.

[0047] The single-layer double-sided weft knitting structure 31 of the embodiment is knitted by 30D / 36F inelastic polyester yarn, the surface flat knitting structure 11 is knitted by 50D / 36F high-elastic polyester yarn, and the back flat knitting structure 21 is knitted by 50D / 48F polypropylene yarn.

[0048] The elastic shrinkage characteristics of the surface 1 high-elastic polyester yarn can dynamically adjust the fit with the back 2, eliminate the thickness redundancy caused by the interlayer gap, and reduce the overall thickness of the fabric. At the same time, the elastic surface 1 generates pressure conduction to the back 2 when stretched, forming a certain constraint effect, which can improve the tear resistance of the back 2 and maintain the overall ductility of the fabric.

[0049] Example Two

[0050] The embodiment is similar to example one, and the main difference between the two is the yarn. The single-layer double-sided weft knitting structure 31 of the embodiment is knitted by 50D / 36F moisture-wicking polyester yarn, the surface flat knitting structure 11 is knitted by 50D / 36F PBT / PET composite elastic yarn, and the back flat knitting structure 21 is knitted by 50D / 48F polypropylene yarn.

[0051] The PBT / PET composite elastic yarn has more stable elastic recovery force and fatigue resistance characteristics than the high-elastic polyester yarn. The physical moisture-conducting channel formed by the eight-shaped fiber cross-section can further enhance the diffusion and quick-drying efficiency of the fabric. The moisture-wicking polyester yarn can also further improve the moisture-conducting effect by building a moisture-conducting channel with fiber grooves. The inelastic polyester yarn and high-elastic polyester yarn of example one lack active moisture-conducting structures. Therefore, the embodiment has more excellent elastic recovery rate, moisture-wicking performance and wearing comfort compared to example one.

[0052] Example Three

[0053] The main difference between the two is the yarn, the single-layer double-sided weft knitted fabric 31 of the present embodiment is knitted by 50D / 36F PBT / PET composite elastic yarn, the surface layer plain knitted fabric 11 is knitted by 50D / 36F moisture-absorbing and sweat-repellent polyester yarn, and the inner layer plain knitted fabric 21 is knitted by 50D / 48F polypropylene yarn. The weight ratio of the moisture-absorbing and sweat-repellent polyester yarn, the PBT / PET composite elastic yarn and the polypropylene yarn is 40.2%:26.2%:33.6%. The quick-drying effect of the unidirectional wetting fabric of the present embodiment is slightly better than that of Example Two.

[0054] The performance test results of the unidirectional wetting fabric of the present embodiment are shown in the following table:

[0055]

[0056] Example Four

[0057] The main difference between the two is the yarn, the single-layer double-sided weft knitted fabric 31 of the present embodiment is knitted by 50D / 36F PBT / PET composite elastic yarn, the surface layer plain knitted fabric 11 is knitted by 50D / 36F moisture-absorbing and sweat-repellent polyester yarn, and the inner layer plain knitted fabric 21 is knitted by 50D / 48F polypropylene yarn. The weight ratio of the moisture-absorbing and sweat-repellent polyester yarn, the PBT / PET composite elastic yarn and the polypropylene yarn is 40.2%:26.2%:33.6%. The quick-drying effect of the unidirectional wetting fabric of the present embodiment is slightly better than that of Example Two.
