Description

Technical Field

[0001] The utility model relates to the field of fabrics, and more specifically, to a windproof and waterproof composite knitted fabric. Background Art

[0002] Fabrics are the main materials for making our daily textiles. Existing fabrics are divided into composite fabrics and single-layer fabrics according to the number of layers. Composite fabrics are composed of multiple functional layers combined together, which makes the functionality of the fabric more enhanced.

[0003] Some existing fabrics need to have windproof and waterproof properties. Therefore, in order to ensure the overall windproof and waterproof properties of the fabric, people will directly compound a layer of waterproof coating on the surface of the fabric, so that the fabric has waterproof properties while the wind is not easy to penetrate the fabric, thereby ensuring the overall windproof and waterproof properties of the fabric. However, the waterproof coating is fixed on the fabric, and some fabrics need to have unidirectional extension requirements, which leads to a certain stretching of the waterproof coating along with the fabric during the stretching process of the fabric, thereby making it more likely that the windproof coating will crack at the stretched position.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a windproof and waterproof composite knitted fabric.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a windproof and waterproof composite knitted fabric, including a base layer, the base layer including an elastic part and a low-elastic part, a groove located in the low-elastic part is formed on one side of the base layer, a low-elastic layer is provided on the side of the base layer where the groove is provided, the low-elastic layer is located above the groove and is recessed into the groove, the base layer and the low-elastic layer are stitched together by waterproof yarn, all the waterproof yarns are provided on the low-elastic part and the waterproof yarns are woven on the side of the low-elastic layer facing away from the base layer to form a plurality of convex strips, and a waterproof coating is provided on the side of the low-elastic layer facing away from the base layer.

[0007] The utility model is further configured as follows: the low-elastic part is formed by weaving and stacking the yarns of comb bar GB1 and comb bar GB2, the elastic part is woven by the yarns of comb bar GB3, and the diameters of the yarns of comb bar GB1 and comb bar GB2 are both larger than the diameter of the yarn of comb bar GB3.

[0008] The utility model is further configured as follows: the yarn of the comb bar GB1 is twisted with low-elastic polyester yarn, the yarn of the comb bar GB2 is twisted with bamboo fiber, and the yarn of the comb bar GB3 is twisted with high-elastic polyester yarn.

[0009] The utility model is further configured as follows:

[0010] The yarn laying number of the combing bar GB1 yarn is 1-0 / 1-2 / / seven through and three empty;

[0011] The yarn laying number of the combing bar GB2 yarn is 1-2 / 1-0 / / seven through and three empty;

[0012] The yarn laying numbers of the combing bar GB3 yarn are 9-8 / 9-10 / / three through and seven empty.

[0013] The utility model is further configured as follows: the low-elastic layer is woven with low-elastic yarn, the low-elastic yarn is twisted with low-elastic polyester yarn, and the weaving density of the low-elastic layer is 120-150 strands / inch.

[0014] The utility model is further configured as follows: a plurality of hydrophobic fleeces are arranged on the surface of the waterproof yarn, and the waterproof yarn is formed by twisting polyester fibers.

[0015] In summary, the utility model has the following beneficial effects: during the stretching process, the low-elastic part is not easy to stretch, and the stretching position is concentrated on the elastic part.

The amount of stretching on the low-elastic layer is relatively small or even non-existent, so that the waterproof coating will not stretch with the low-elastic layer, thereby ensuring the integrity of the waterproof coating and reducing the possibility of cracking of the waterproof coating. The convex strips protrude from the outside of the fabric, so that after the fabric is rubbed for a long time, the waterproof coating on the convex strips will be worn off first, but the convex strip position itself has good windproof and waterproof performance, so that the windproof and waterproof performance of the fabric itself is guaranteed to a certain extent.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] A windproof and waterproof composite knitted fabric, such as Figure 1 As shown, it includes a base layer, and the base layer includes an elastic part 1 and a low-elastic part 2. The thickness of the low-elastic part 2 is greater than that of the elastic part 1. A groove 3 located at the low-elastic part 2 is formed on one side of the base layer. A low-elastic layer 4 is provided on one side of the base layer where the groove 3 is provided. The low-elastic layer 4 is located above the groove 3 and is recessed into the groove 3. The low-elastic layer 4 is located at the low-elastic part 2 and fits the low-elastic part 2. The base layer and the low-elastic layer 4 are stitched and compounded by waterproof yarn. All waterproof yarns are arranged on the low-elastic part 2 and the waterproof yarn is woven on the side of the low-elastic layer 4 facing away from the base layer to form a plurality of convex strips 5, so that the low-elastic layer 4 located above the groove 3 is not fixed by the waterproof yarn. A waterproof coating 6 is provided on the side of the low-elastic layer 4 facing away from the base layer. During the stretching process of the fabric, because the elasticity of the elastic part 1 is better than that of the low-elastic part 2 and the thickness of the low-elastic part 2 is thicker, the low-elastic part 2 is not easy to stretch during the stretching process, and the stretching position is concentrated on the elastic part. On the force part 1, during the stretching process of the fabric, the part of the low-elastic layer 4 sunken in the groove 3 slowly moves back to the groove 3 until the low-elastic layer 4 is straightened at the position above the groove 3, and the low-elastic layer 4 only becomes flat with the stretching, and the amount of stretching on the low-elastic layer 4 is relatively small or even non-existent, so that the waterproof coating 6 will not stretch with the low-elastic layer 4, thereby ensuring the integrity of the waterproof coating 6 and reducing the possibility of cracking of the waterproof coating 6. The convex strips 5 are embroidered on the low-elastic layer 4 by an embroidery machine, so the weaving density of the waterproof yarn at the position of the convex strips 5 is relatively high, and the gaps between the waterproof yarns are relatively small, so that the convex strips 5 have a certain waterproof performance. The convex strips 5 protrude from the outside of the fabric, so that after the fabric is rubbed for a long time, the waterproof coating 6 on the convex strips 5 will be worn off first, but the position of the convex strips 5 itself has good windproof and waterproof performance, so that the windproof and waterproof performance of the fabric itself is guaranteed to a certain extent.

[0023] like Figure 2 , Figure 3 and Figure 4As shown, the low-elastic part 2 is formed by weaving and stacking the yarns of the comb bar GB1 and the comb bar GB2, and the elastic part 1 is woven by the yarns of the comb bar GB3. The base layer is woven in the form of knitting, thereby ensuring that the base layer is relatively soft as a whole. The low-elastic part 2 is formed by stacking the yarns of the comb bar GB1 and the comb bar GB2, thereby ensuring that the thickness of the low-elastic part 2 is greater than the thickness of the elastic part 1. The diameters of the yarns of the comb bar GB1 and the comb bar GB2 are both greater than the diameter of the yarns of the comb bar GB3. This arrangement further ensures the thickness difference between the low-elastic part 2 and the elastic part 1, so that the groove 3 The position is relatively obvious. The yarn of comb bar GB1 is twisted with low-elastic polyester yarn. The low-elastic polyester yarn has the characteristics of low elasticity and high strength, so that the low-elastic part 2 has the characteristics of low elasticity and high strength. The yarn of comb bar GB2 is twisted with bamboo fiber. Bamboo fiber has certain antibacterial and antibacterial properties, which can inhibit the growth of bacteria on the base layer and reduce the growth of bacteria on the base layer. The yarn of comb bar GB3 is twisted with high-elastic polyester yarn. The high-elastic polyester yarn has the characteristics of good elasticity and high strength. While ensuring the elasticity of the elastic part 1, the strength of the elastic part 1 is also guaranteed to a certain extent.

[0024] The yarn laying number of the yarn of combing bar GB1 is 1-0 / 1-2 / / seven through and three empty;

[0025] The yarn laying numbers of the yarn of combing bar GB2 are 1-2 / 1-0 / / seven through and three empty;

[0026] The yarn number of the GB3 yarn is 9-8 / 9-10 / / three through and seven empty.

[0027] The yarns of the combing bar GB1, the combing bar GB2 and the combing bar GB3 are all warp plain weaves. The warp plain weave can ensure the stability and durability of the fabric because each warp yarn forms a loop in two consecutive longitudinal rows, thereby enhancing the structural strength of the fabric.

[0028] like Figure 1As shown, the low-elastic layer 4 is woven with low-elastic yarn, and the low-elastic yarn is twisted with low-elastic polyester yarn. The weaving density of the low-elastic layer 4 is 120-150 strands / inch. In this embodiment, the weaving density of the low-elastic layer 4 is 150 strands / inch. The weaving density of the low-elastic layer 4 is high and the elasticity of the low-elastic yarn is low, so that the fabric is not easy to stretch during the stretching process, thereby ensuring the integrity of the waterproof coating 6. A plurality of hydrophobic fleeces are arranged on the surface of the waterproof yarn. The waterproof yarn is twisted with polyester fiber. The polyester fiber has the characteristics of high strength and good waterproof performance, thereby ensuring the waterproofness of the waterproof yarn and the strength of the waterproof yarn as a suture. The hydrophobic fleece can block the gap between the waterproof yarn and the waterproof yarn, so that it is more difficult for moisture to pass through the convex strip 5, further ensuring the waterproofness and windproofness of the convex strip 5. The hydrophobic fleece is made of nylon fiber. The waterproof yarn is passed through an adhesive, and then through a hydrophobic fleece pile with static electricity, and is fixed by a fixing box to complete the fixation of the hydrophobic fleece.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
