Description

Three-dimensional unidirectional moisture-conducting elastic fabric based on knitted structure and preparation method thereof
Technical Field
The invention belongs to the technical field of functional fabrics, and relates to a three-dimensional unidirectional moisture-conducting elastic fabric based on a knitted structure and a preparation method thereof.
Background
If the sweat is secreted by a human body too much, the sweat cannot be quickly conducted and evaporated by the fabric, so that the human body feels uncomfortable, bacteria can breed on the body surface, and the health of the human body is damaged, so that the physiological comfort of the garment fabric is obviously influenced by the microclimate between the skin and the fabric. Meanwhile, for sportsman's moisture absorption and perspiration performance is of great importance to promotion sportsman's surface fabric because some parts or joints of human body can produce a large amount of sweat steam and sweat, if these sweat moisture do not obtain timely dissipation and discharge, can produce the sensation of moist stifle, influence sportsman's clothing sensation of wearing and the mood of participating in the contest, and then influence sportsman's performance and match score.
In the current literature and patents, there are a large number of fabrics with unidirectional moisture-conducting performance, and how to quickly conduct the obvious sweat to the surface layer of the fabric and quickly obtain evaporation is an important research direction for moisture absorption and sweat releasing. At present, the research aiming at the performance mainly focuses on three implementation modes of moisture absorption and sweat releasing fiber development, fabric structure design and functional finishing, but the research on the unidirectional moisture conductivity of the elastic fabric is rarely related.
Disclosure of Invention
The invention aims to overcome the problems in the prior art and provide a three-dimensional unidirectional moisture-conducting elastic fabric based on a knitted structure and a preparation method thereof, and particularly aims to develop a weft-knitted spacer fabric which has excellent elasticity and a unidirectional moisture-conducting function, so that the weft-knitted spacer fabric can be used as a racing speed analog competition clothing sports fabric, and the problem that a large amount of water vapor generated by a human body cannot be rapidly discharged out of the human body under the condition of high-speed sports is solved.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a three-dimensional unidirectional moisture-conducting elastic fabric based on a knitting structure is of a three-layer weft knitting structure, the surface layer is of a double-sided weft knitting structure with tucks, the inner layer is of a single-sided weft knitting plain stitch structure, and the middle layer is of a double-sided tuck structure (the middle layer is used for connecting the surface layer with the inner layer and simultaneously transferring moisture from the inner layer to the surface layer by utilizing a capillary effect);
the surface layer is formed by interweaving hydrophilic fiber yarn and elastic fiber yarn, the hydrophilic fiber yarn and the elastic fiber yarn are arranged in a plating mode, the hydrophilic fiber yarn is always arranged in front of the elastic fiber yarn, or the hydrophilic fiber yarn and the elastic fiber yarn are interwoven by first covering yarn, the first covering yarn takes the elastic fiber yarn as core yarn, and the hydrophilic fiber yarn as outer covering yarn; the middle layer is composed of moisture-conductive fiber yarns; the inner layer is formed by interweaving hydrophobic fiber yarns and elastic fiber yarns, the hydrophobic fiber yarns and the elastic fiber yarns are arranged in a plating mode, the hydrophobic fiber yarns are always arranged in front of the elastic fiber yarns, or the hydrophobic fiber yarns and the elastic fiber yarns are interwoven to form second covering yarns, the second covering yarns take the elastic fiber yarns as core yarns, and the hydrophobic fiber yarns as outer covering yarns;
the monofilament fineness of the hydrophobic fibers of the inner layer is larger than that of the moisture-conducting fibers of the middle layer, and the monofilament fineness of the moisture-conducting fibers of the middle layer is larger than that of the hydrophilic fibers of the surface layer; the elastic fiber mainly plays a role in generating elasticity, and the single fiber fineness does not need to be considered;
the F number of the hydrophobic fiber yarn of the inner layer is smaller than that of the moisture-conducting fiber yarn of the middle layer, and the F number of the moisture-conducting fiber yarn of the middle layer is smaller than that of the hydrophilic fiber yarn of the surface layer; the elastic fiber in the invention mainly plays a role in generating elasticity, and the F number of the yarn does not need to be considered.
In the prior art, a fabric which has excellent elasticity and a one-way moisture-conducting function has a technical blank. The main reason that the fabric is difficult to take elasticity and one-way moisture-conducting performance into account is that after the elasticity of the fabric is increased, the transverse density and the longitudinal density are increased, so that the pores between fibers are reduced, water vapor is not easy to conduct out of the pores, and the larger the elasticity of the fabric is, the poorer the one-way moisture-conducting performance is.
The invention adjusts the knitting structure of the fabric, adjusts the surface layer from a plain knitting structure to a double-sided weft knitting structure with tucks, and simultaneously, the middle layer is arranged to be a double-sided tuck structure, so that the surface layer and the inner layer are connected through tucks, large pores are generated at the connection part, the three-layer structure is locally changed into a two-layer structure (the surface layer is overlapped with the tucks of the middle layer at the position where the tucks are arranged, so that the surface layer and the middle layer are overlapped to form a two-layer structure), the unidirectional moisture-conducting performance of the fabric can be improved through the structural adjustment, and the unidirectional moisture-conducting performance is prevented from being damaged due to the increase of elasticity.
The fabric has excellent elasticity, because the elastic fibers are introduced into the surface layer and the inner layer, the middle layer only has tucks and does not have knitted loops, and the elasticity of the fabric is not influenced, so that the elastic fibers do not need to be introduced into the middle layer, the middle layer is totally moisture-conductive fibers, the unidirectional moisture-conductive capability of the fabric can be improved, and the unidirectional moisture-conductive capability of the fabric can be reduced if the proportion of the moisture-conductive fibers is reduced after the elastic fibers are mixed;
the fabric of the invention has excellent one-way moisture-conducting performance because: (1) the surface layer is of a double-sided weft knitting structure with tucks, the middle layer is of a double-sided tuck structure, and the surface layer and the middle layer can generate a 1-level differential capillary effect and quickly transfer water vapor to the surface layer; (2) the surface layer is a hydrophilic layer containing hydrophilic fibers, the middle layer is a moisture-conducting layer containing moisture-conducting fibers, the inner layer is a hydrophobic layer containing hydrophobic fibers, a 2-level differential capillary effect can be generated, in the movement process, water vapor is transferred from the hydrophobic layer to the hydrophilic layer, namely from the inner layer to the surface layer, and the moisture-conducting layer plays a role in better assisting water vapor transfer; (3) the monofilament titer of the hydrophobic fiber of the inner layer is greater than that of the moisture-conducting fiber of the middle layer, the monofilament titer of the moisture-conducting fiber of the middle layer is greater than that of the hydrophilic fiber of the surface layer, and a 2-level differential capillary effect can be generated, and in the movement process, water vapor is transferred from a thick layer of single fiber to a thin layer of single fiber, namely from the inner layer to the surface layer; (4) inner layer of hydrophobicThe F number of the sexual fiber yarn is smaller than that of the wet guide fiber yarn in the middle layer, the F number of the wet guide fiber yarn in the middle layer is smaller than that of the hydrophilic fiber yarn in the surface layer, a 2-level differential capillary effect can be generated, and in the moving process, water vapor is transferred from the layer with the smaller F number to the layer with the larger F number, namely from the inner layer to the surface layer; (5) the use of the elastic fiber and the high machine number in the fabric increases the number of yarns in the plane and thickness dimension compared with the common unidirectional moisture-guiding fabric (under the same weaving efficiency of the same machine, under the condition that the width of the fabric is reduced by W% and the length of the fabric is reduced by V% after the elastic fiber is added, the transverse density and the longitudinal density in the plane are increased
Figure BDA0002664174180000021
And
Figure BDA0002664174180000022
because the number of yarns in one loop is not changed, the number of yarns in the plane is correspondingly larger than that of the common unidirectional moisture-conducting fabric, and the higher the elastic fiber content is, the larger the number of yarns in the unit area in the plane is; similarly, the increase of the transverse density and the longitudinal density in the plane causes the yarn angle of the middle layer in the thickness direction to be more vertical to the surface layer and the inner layer, so that the number of yarns in the thickness direction is correspondingly increased; the yarn figure that highly machine number surface fabric's violently close indulges densely packed increase, and in the same way, can increase plane and thickness dimension), with the single fiber quantity in the greatly increased unit length, the pore quantity between the single fiber quantity decision fibre, the single fiber quantity increase can lead to the pore quantity increase to promote capillary effect greatly.
In addition, the elastic fibers in the fabric do not damage the unidirectional moisture-conducting conditions in the steps (1) to (4) after being stretched, so that the fabric still has good unidirectional moisture-conducting performance.
