Abstract
A molded knitted fabric is a double-layer knocking-over through mesh structure, and lining yarns at knocking-over through meshes are covered on surface yarns in a turning manner, wherein the lining yarns are polyurethane covered yarns. The formed knitted fabric has excellent perspiration and air permeability, can keep the dry feeling of the skin side, and is particularly suitable for manufacturing outdoor sportswear.
Description
The invention belongs to the field of knitting, and particularly relates to a formed knitted fabric with excellent sweat discharging and air permeability.
Research shows that for sports with large amount of exercise, such as mountain climbing, navigation, riding and the like, a human body usually generates a large amount of heat and sweat, and if the heat and sweat cannot be discharged outside the clothes in time, uncomfortable feeling such as damp and cold can be generated. The existing sports wear on the market generally selects water-absorbing quick-drying fibers and combines a mesh structure, so that the problems of poor perspiration and insufficient heat dissipation (air permeability) are improved to a certain extent. However, the problems of perspiration and heat dissipation are not fundamentally solved because the mesh structure cannot be maximized and the mesh effect cannot be achieved due to the limitation of knitting conditions and the like.
Currently, many studies have been made on forming an open-knit fabric. For example, in order to solve the problem of the raveling of the mesh fabric in the reverse knitting direction, patent document CN101967723B discloses a method for opening a seamless knitted underwear, in which hot-melt yarns are added to each of the 6 th, 4 th and 2 nd lines before the opening, and the hot-melt yarns are knitted, and then suspended and steamed after the opening, so that the hot-melt yarns are sufficiently melted before dyeing, and the other yarns interwoven with the hot-melt yarns are bonded together, and the loops are fixed by the bonding, and the raveling and the miss of the stitches are prevented regardless of the size of the opening. Although the method can realize mesh maximization and improve air permeability, most of the thermal fuses depend on import from abroad, and a steaming process needs to be added, so that the cost is high and the process control difficulty is high.
In order to solve the problem of discomfort caused by the sticking of clothes to the body after sweating, patent document CN103243472B discloses a woven fabric in which an uneven pattern piece woven by a single-needle multi-row float knitting technique and a mesh pattern piece woven by an overhead plating knitting technique are seamlessly joined, but the mesh of the overhead plating knitting technique has a non-through structure, the mesh size is also limited, the air convection effect is limited, and the phenomenon of sweat retention occurs even when a large amount of sweat is generated. For another example, patent document CN205757306U discloses a one-way moisture-guiding functional seamless underwear, which adopts a honeycomb mesh structure formed by combining rib weave and tuck weave, and the skin-facing surface adopts superfine denier polypropylene fiber, so that the underwear has the functions of moisture absorption, quick drying, one-way moisture guiding, and avoiding the adhesion phenomenon between clothes and body, but also has poor sweat releasing and air permeability because the honeycomb mesh is not a through structure.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a molded knitted fabric which is inexpensive, has no run-off of openings (meshes), and is excellent in perspiration and air permeability.
The technical solution of the invention is as follows:
the formed knitted fabric is a double-layer knockover through mesh structure, and lining yarns at the knockover through mesh part are covered on the surface yarns in a turnover mode, wherein the lining yarns are polyurethane covered yarns.
The invention forms through hollow openings (meshes) on the knitted fabric by using a knocking-over knitting mode, thereby obtaining good perspiration property and air permeability. Meanwhile, the lining yarns are wrapped by the polyurethane series machine, compared with polyurethane series empty wrapping yarns and the like, the yarn structure is stable, and the problem that the reverse knitting direction at the opening of the knocking-over opening is loosened can be effectively avoided.
(1) Fig. 1 is a plan pictorial view (20 times digital microscope) of a single-sided formed knitted fabric of the present invention, wherein a is the surface of the knitted fabric and B is the back surface of the knitted fabric.
(2) Fig. 2 is a plan pictorial view (digital microscope, 30 x) of a single double layer, loopless through-mesh, wherein a is the loopless through-mesh area and b is the inner wire turned over covering the outer wire area.
The formed knitted fabric is formed by knitting surface yarns and lining yarns, has a double-layer knockover through mesh structure, and the lining yarns at the knockover through mesh part are covered on the surface yarns in a turnover manner, wherein the lining yarns are polyurethane covered yarns.
The invention uses plating stitch to weave, and forms a through mesh structure with a loop on the knitted fabric after the loop is removed. The through-mesh structure refers to a mesh structure formed by knocking over the front and back layers formed by the front and back threads and penetrating through the front and back layers, wherein the through-mesh structure refers to a hollow effect at the mesh position, and no yarn exists by visual observation. The structure of the knockover through mesh is a special structure in the knitting field, some paths of yarns are automatically sheared during the knitting process, a knitting needle is lifted, the lifted knitting needle cannot catch new yarns for forming a loop, an old loop on the knitting needle falls off from the needle, and the loop is partially disconnected in the longitudinal direction, so that the knockover through mesh is formed. Compared with meshes formed by tucking, floating threads and the like, the mesh with the knockover penetrating function can be made larger, the penetrating effect can be achieved, the problems of poor perspiration and insufficient heat dissipation (air permeability) can be effectively solved, and the dry and comfortable feeling of the skin can be kept under the condition that a human body sweats in a large amount during exercise, so that the comfortable feeling is brought.
As is well known, polyurethane series air-covered yarn (ACY) is a yarn formed by simultaneously drawing an outer-covered fiber filament and a Polyurethane (PU) fiber through an air nozzle and regularly spraying and pressing the outer-covered fiber filament and the PU fiber by high-compressed air to form a cross point. In the invention, when the inner yarn adopts the polyurethane series empty covering yarn, the outer covering fiber filament is combined with the polyurethane fiber through the interlacing points, so that the outer covering fiber filament is easy to be hooked out at the position of the knockover through mesh to cause shedding in the use process; further, when the bare polyurethane yarn (bare yarn) is used as the back yarn, the bare polyurethane yarn floats at the position of the loop-off position due to its large elastic recovery when the mesh is formed by the loop-off, which affects the appearance. The polyurethane covered yarn is a yarn which is formed by continuously rotating an outer covering fiber filament, winding the outer covering fiber filament on a core filament polyurethane fiber which is drafted at a constant speed, and twisting the outer covering fiber filament to have a certain twist. The processing mode enables the outer-coated fiber filament to be tightly wrapped on the polyurethane fiber of the core part, so that the problem of filament hooking is not easy to occur; under the action of tension of the coil and yarn shrinkage in the scouring and dyeing stage, the inner yarn is turned over and covers the surface yarn, so that meshes obtained after knocking over are fixed, and the problem of falling off in the reverse knitting direction is not easy to occur; meanwhile, the inner yarn is covered on the surface yarn in a turnover mode, so that the thickness of the fabric can be improved to a certain degree, and the heat preservation performance is guaranteed.
In the present invention, the fiber material of the outer covering fiber filament is not particularly limited, and may be polyester, polyamide, polypropylene, or the like. In view of skin-friendly properties, polyamide-based long fibers are preferred. The fineness of the over-wrapped fiber filaments is preferably 20 to 70 deniers (D) in consideration of turnover rate and weight reduction of the garment.
In the present invention, the surface yarn is not particularly limited, but is preferably a hydrophobic fiber for further improving perspiration and quick-drying properties. The hydrophobic fibers herein mean fibers having a official moisture regain of 4.5% or less, such as polyester fibers and polypropylene fibers, or fibers having a water-repellent resin attached to the surface of a single fiber. The fibers to which the water-repellent resin is attached to the surface of the single fibers may be polyester fibers, polyamide fibers, or the like, and the water-repellent resin used may be a fluorine-containing water-repellent resin, a carbonized water-repellent resin, or the like. Because the moisture absorption rate of the hydrophobic fiber is low, sweat is not easy to absorb into the fiber, and the wet and sticky feeling and the wet and cold feeling of a human body can not be caused. In view of obtaining better dry and light weight properties, polypropylene fibers are more preferably used as the surface yarn in the present invention, because the moisture regain of polypropylene fibers is close to zero, the surface yarn hardly absorbs moisture, and the density of polypropylene fibers is only 0.91g/cm3The fiber with the lightest density in the chemical fiber.
In the invention, the polyurethane fiber in the polyurethane series covered yarn used by the lining yarn can be common polyurethane fiber or hot melt polyurethane fiber. Wherein the common polyurethane fiber is formed by connecting a soft and extensible polyurethane soft chain segment and a hard chain segment; the hot melt type polyurethane fiber is obtained by adding isocyanate, diol, chain extender and the like on the basis of the structure to change the interaction of a hard segment and a flexible molecular chain segment in a molecular structure, and can be fused under a certain temperature condition, wherein the fiber comprises 3 types of low temperature type (the setting temperature is 95-110 ℃), medium temperature type (the setting temperature is 110-130 ℃) and high temperature type (the setting temperature is 130-160 ℃). In the invention, the hot melt type polyurethane fiber is preferred, so that the hot melt type polyurethane fiber can be melted in a shaping process at high temperature, the processing steps can be reduced, the size of the fabric is ensured to be stable, and the mesh after knocking over is well fixed and is not loosened.
In theory, sweat is more easily discharged from the openings as the open area of the loop-releasing through-mesh is larger, and the air permeability and the sweat permeability of the knitted fabric are better, but in consideration of basic properties such as the strength of the knitted fabric, the ratio of the open area of the loop-releasing through-mesh to the entire area of the molded knitted fabric is preferably more than 5% and less than 50%. When the proportion of the open area of the knockover through meshes is less than or equal to 5%, the perspiration, air permeability and heat dissipation of the fabric tend to be poor; on the contrary, when the ratio of the open area of the knockover through mesh is 50% or more, the physical properties of the fabric such as tensile strength and bursting strength may be problematic due to the excessively large hollow area. In view of the above, the ratio of the open area of the knockover through-mesh is preferably greater than 5% and less than 50%, more preferably 15% to 45%, and still more preferably 20% to 40%.
The inner yarn overturning and covering surface yarn means that after the loops which are separated from the needles lose the serial sleeves, the loops are overturned to the surface layer under the action of the inner loop arc and the component force of the elastic covering yarn, and the inner yarn appears on the surface layer and covers the surface yarn. In the present invention, it is preferable that the tucked through-mesh portion has a ratio of an area of the back yarn turned over to cover the top yarn to the entire area of the molded knitted fabric, which is greater than 20% and less than 40%. When the area of the inner yarn covered by the surface yarn in the overturning way is less than or equal to 20%, the fabric is likely to have the phenomena of raveling and yarn hooking; when the proportion is more than or equal to 40 percent, the requirement on the surface yarn is high, if the surface yarn with high rolling shrinkage rate is needed, in addition, the problem that the wearing is inconvenient can be caused by excessively thick cloth surface. More preferably, the area of the surface silk covered by the inner silk in the overturning way accounts for more than 25% and less than 35%.
Preferably, the molded knitted fabric of the present invention has a water absorption rate of 80% to 90% and a water retention rate of the inner layer of 1% to 3%. The higher the water absorption, the more sweat is excreted under a certain pressure; meanwhile, the lower the water retention rate of the inner layer, the less sweat remained on the surface of the skin of the human body, and the drier and more comfortable the skin surface.
Preferably, the composition is prepared according to JIS L1096: the molded knitted fabric of the present invention has an air flow of 100cm measured by 2010A method3/cm2S or more, more preferably, the ventilation amount is 200cm3/cm2S or more. The larger the ventilation value, the better the ventilation.
Preferably, the molded knitted fabric of the present invention has a heat retaining CLO value (CLO value) of 0.3 to 0.6. The higher the CLO value, the better the heat retention, even in the case of a large amount of sweating, the better the heat retention is maintained.
