Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

A waterproof knitted fabric is shown in figure 1, and comprises a base layer 1 and a waterproof layer 2, wherein the fabric is formed by compounding two layers, so that the fabric can obtain a plurality of functional layers which are not mutually interfered, the base layer 1 is a rib structure woven by structural yarns 11, the rib structure belongs to one of basic structures of weft knitting, the waterproof knitted fabric has higher elasticity, the base layer 1 has certain tensile capacity, the strength of the fabric is further enhanced, the waterproof layer 2 is formed by a guide bar GB1 and a guide bar GB2, the waterproof layer 2 is woven by adopting a warp knitting process, and the warp knitting structure has the characteristics of high compactness, high strength and the like, so that the interval between yarns of the waterproof layer 2 is reduced, and the waterproof effect of the waterproof layer 2 is further enhanced.

As shown in fig. 6, the structural yarn 11 is formed by twisting cotton fibers, the twisting direction of the structural yarn 11 is Z-twist, and the cotton fibers have strong skin-friendly property, so that the structural formula twisted by the material has strong skin-friendly capability to improve the comfort of the fabric when the fabric is worn, and the Z-twisted yarn has the characteristic of softness and fluffiness, so that the skin-friendly property of the structural yarn 11 can be further enhanced by the arrangement of the twisting direction.

As shown in fig. 2 and 3, the guide bar GB1 is a waterproof yarn 21, the guide bar GB2 is a reinforcing yarn 22, the waterproof yarn 21 is used for providing waterproof capability to the waterproof layer 2, and the reinforcing yarn 22 is used for reinforcing the overall structural strength of the waterproof layer 2, so that the waterproof yarn 21 has a longer service life, and further the waterproof layer 2 is ensured to have stable waterproof capability, and meanwhile, the number ratio of the guide bar GB1 to the guide bar GB2 is 3:1, and further the waterproof layer 2 can be ensured to have sufficient waterproof capability.

As shown in fig. 4, the waterproof yarn 21 is formed by twisting polyester fibers, and the polyester fibers have strong hydrophobicity, so that when moisture falls on the waterproof layer 2, the moisture can not be absorbed by the waterproof yarn 21 and stays on the surface of the waterproof layer 2, thereby realizing the waterproof effect of the fabric, the twist degree of the waterproof yarn 21 is 1500-2000 twists/m, preferably 2000-twists/m, and the yarn with higher twist degree has higher strength and compactness, and can be used for preventing the moisture from penetrating the waterproof layer 2 from gaps among the polyester fibers, and further enhancing the waterproof capability of the waterproof layer 2.

As shown in fig. 5, the reinforcing yarn 22 is woven by using a CVC yarn, the diameter of the reinforcing yarn 22 is smaller than that of the waterproof yarn 21, and the CVC yarn is a cotton-polyester blended yarn, which has the softness of cotton fibers and the high strength of polyester fibers, so that after the reinforcing yarn 22 is added into the waterproof layer 2, a certain toughness can be provided for the waterproof layer 2, and further, the waterproof layer 2 is guaranteed to have a certain tensile strength, and the structural integrity of the fabric is guaranteed, and the diameter of the reinforcing yarn 22 smaller than that of the waterproof yarn 21 enables the reinforcing yarn 22 to be hidden under the waterproof yarn 21 during weaving, and further, the waterproof yarn 21 is guaranteed to be positioned on the surface of the fabric, and the waterproof property of the fabric is further guaranteed.
