Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and more specifically, to windproof and warm chemical fiber fabrics. Background Technology

[0002] Chemical fiber fabrics generally include two main categories: man-made fiber fabrics and synthetic fiber fabrics. Man-made fiber fabrics and synthetic fiber fabrics can be further divided into viscose, nylon, polyester, vinylon, acrylic, polypropylene fabrics, etc., depending on the different fiber components in the chemical fiber fabrics. Compared with natural fiber fabrics, chemical fiber fabrics generally have higher strength, durability and elasticity, and are not easily deformed. Chemical fiber fabrics have advantages such as being crisp, easy to wash and quick-drying, and resistant to insects, moths and mildew.

[0003] To give synthetic fiber fabrics good windproof and warmth-keeping properties, a windproof coating is usually applied to the outer end face. To improve the warmth of synthetic fiber fabrics, the density of the base fabric can be increased, the thickness of the base fabric can be increased, or a pile can be added to the inner end face of the base fabric. However, increasing the thickness of the base fabric or adding a pile will increase the overall thickness and weight of the synthetic fiber fabric, resulting in a poor wearing experience.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide windproof and warm chemical fiber fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the windproof and heat-insulating chemical fiber fabric includes a base layer, on one side end face of the base layer are fixedly connected a first disturbance flow strip and a second disturbance flow strip, the horizontal cross-sectional shape of the first disturbance flow strip and the second disturbance flow strip are both arc-shaped, a plurality of the first disturbance flow strips and a plurality of the second disturbance flow strips are linearly arrayed along the warp direction of the base layer to form a disturbance flow group, the opening direction of the first disturbance flow strip in a single disturbance flow group is opposite to the opening direction of the second disturbance flow strip, a heat-insulating strip is provided between adjacent disturbance flow groups, and a windproof layer is provided on the other side end face of the base layer.

[0007] The present invention is further configured such that several of the aforementioned turbulence groups are arranged in a linear array along the latitudinal direction of the base layer.

[0008] The present invention is further configured such that: the cross-sectional size of the first and second turbulence strips is the same, and the first and second turbulence strips in the turbulence group are arranged alternately.

[0009] The present invention is further configured such that the height of the first deflector strip is equal to the height of the second deflector strip, and the height of the heat-insulating strip is greater than the height of the second deflector strip.

[0010] The present invention is further configured such that: the fabric structure of the base layer is a warp-patterned structure, the ground warp yarn and ground weft yarn of the base layer are warm-insulating yarns, the patterned warp yarn of the base layer is abrasion-resistant yarn, and a plurality of the first and second turbulence strips are formed from the patterned warp yarns.

[0011] The present invention is further configured such that the heat-insulating strip is made of several nylon short fibers flocked together.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. The first and second baffle strips on the base layer will make the gas flow more complex and unstable, resulting in increased flow resistance and reduced air flow speed. A relatively still air layer is formed between the base layer and the human body. The air layer can play a role in heat insulation and reduce the loss of heat to the external environment by convection.

[0014] 2. The insulation strips set between adjacent turbulence groups further increase the complexity of the inner end face of the base layer and increase the flow resistance of the airflow, while the windproof layer on the other side of the base layer provides windproof function for the base layer.

[0015] 3. Compared to the method of forming a pile layer by flocking or brushing on one side of the base layer, the method of increasing the complexity and instability of airflow by using deflector strip one, deflector strip two and insulation strip to ensure the insulation effect of the base layer. This method reduces the thickness and weight of the base layer and has better practicality. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Windproof and warm synthetic fiber fabrics, such as Figure 1 , Figure 2 and Figure 3As shown, two minor interference flow strips, one 2 and two minor interference flow strips 3, are provided on one end face of the base layer 1. The horizontal cross-sectional shape of the two minor interference flow strips 1 and 2 is arc-shaped, and the cross-sectional size of the two minor interference flow strips 1 and 2 is the same. The two minor interference flow strips 1 and 2 are linearly arrayed along the meridian direction of the base layer 1 to form a minor interference flow group. The opening directions of the two minor interference flow strips 1 and 2 on the interference flow group are opposite to each other. A heat insulation strip 4 is provided between adjacent interference flow groups. A windproof layer 5 is provided on the other end face of the base layer 1. The end face of the base layer 1 with the minor interference flow strips 1 and 2 is the inner side facing the human body, while the end face with the windproof layer 5 is the outer layer that provides wind protection. When the warm airflow flows between the base layer 1 and the human body, the minor interference flow strips 1, 2 and 3 on the base layer 1... The addition of the second and third baffle strips increases the complexity and instability of airflow, leading to increased flow resistance and reduced airflow speed. This creates a relatively still air layer between the base layer 1 and the human body, which acts as an insulation layer, reducing heat loss to the external environment through convection. The insulation strip 4 between adjacent baffle groups further increases the complexity of the inner end face of the base layer 1, increasing airflow resistance. The windproof layer 5 on the other side of the base layer 1 provides wind protection. Compared to the overall flocking or brushing layer formed on one side of the base layer 1, the use of the first and second baffle strips and the insulation strip 4 to increase the complexity and instability of airflow ensures the insulation effect of the base layer 1. The thickness and weight of the base layer 1 are reduced, making it more practical.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the fabric structure of base layer 1 is set as a warp-patterned weave. The ground warp and weft yarns of base layer 1 are set as warm yarns, and the patterned warp yarns of base layer 1 are set as abrasion-resistant yarns. The warm yarn is made of several polyester profiled fibers and viscose fibers twisted together. The cross-section of the polyester profiled fibers is set as a circular hollow cross-section, which can improve the fluffiness and warmth retention of the polyester profiled fibers. Viscose fibers also have a fluffiness characteristic. The polyester profiled fibers and viscose fibers are fed into a twisting machine for twisting to obtain the warm yarn. The abrasion-resistant yarn is made of several nylon fibers twisted together by a twisting machine. During the weaving process of base layer 1, the patterned warp yarns will form protrusions on the surface of base layer 1 after the pattern is formed. By using nylon fibers with good abrasion resistance, the minor interference flow strips 1 and 3 formed by the patterned warp yarns have good abrasion resistance, extending the overall service life of base layer 1. The warm yarn and abrasion-resistant yarn are fed into a multi-arm loom and twisted according to the following... Figure 4 The weave diagram shown is used to weave a base layer 1 with minor interference flow strips 1-2 and 3-3 on the fabric surface. The pattern on the weave diagram is woven in a loop along the weft direction of the base layer 1.

[0024] like Figure 1 , Figure 2and Figure 3 As shown, spoiler strip 2 and spoiler strip 3 have the same cross-sectional size. The horizontal flip angle between spoiler strip 2 and spoiler strip 3 in the spoiler group is 180 degrees, and spoiler strip 2 is offset to the lower left of spoiler strip 3. The opening direction of spoiler strip 2 is opposite to the opening direction of spoiler strip 3. When the airflow passes through spoiler strip 2, it is dispersed to both ends of the spoiler strip. The airflow continues to flow towards the opening of spoiler strip 3. Spoiler strip 3 continues to disperse the airflow, causing it to flow to both ends of spoiler strip 3. Finally, the airflow flows to the insulating strip 4. The height of insulating strip 4 is greater than the height of spoiler strip 2 and spoiler strip 3. Insulating strip 4 can block some of the airflow. As the flow continues, the addition of interference flow strips 1-2, turbulence strip 2-3, and insulation strip 4 increases the complexity of the surface of the base layer 1, increasing the complexity and instability of gas flow, leading to increased flow resistance and thus reducing the air flow speed. This results in the formation of a relatively stationary air layer between the base layer 1 and the human body. Since air has good thermal insulation properties, it can serve as an insulation layer, reducing heat loss and giving the base layer 1 a good insulation effect. If the interference flow group is linearly arrayed along the latitude direction of the base layer 1, the linear array of interference flow groups on the base layer 1 makes the interference effect of the base layer 1 on the airflow more uniform, while ensuring the stability of the overall structure of the base layer 1.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a windproof layer 5 is provided on the end face of the base layer 1 without the airflow deflector 2. The windproof coating can be PU glue, A / C glue, PVC, PE glue, etc. By brushing the windproof coating onto the surface of the base layer 1, the windproof layer 5 formed can increase the overall windproof effect of the base layer 1 and reduce the possibility of damage to the base layer 1 in the external environment. The insulation strips 4 between adjacent deflector groups are formed by electrostatic flocking technology. Glue is applied to the end face of the base layer 1 with the deflector group (at the position between adjacent deflector groups). The base layer 1 is placed in an electrostatic flocking box, and nylon short fibers are electrostatically adsorbed onto the base layer 1 using electrostatic flocking technology. After the glue solidifies, the nylon short fibers are bonded to the base layer 1 to form insulation strips 4. The insulation strips 4 formed by nylon short fibers have good wear resistance, and by adjusting the flocking density to change the mass of the insulation strips 4, the airflow speed can be reduced, thereby improving the overall insulation effect of the base layer 1.
