TECHNICAL FIELD

The present disclosure relates to the technical field of knitted fabrics, and more particularly to a comfortable breathable warp-knitted fabric free of deformation, yarn hooking and unraveling.

BACKGROUND ART

Existing knitted fabrics usually have the following defects: 1. the fabrics are prone to deformation, yarns are prone to being hooked, and the fabrics need to be improved in comfortableness and breathability, 2. the fabrics are prone to unraveling during shearing; 3. shearing the fabrics results in a lot of losses; to reduce the shearing loss of the fabrics, the fabrics are usually sheared along with an inter-locked edge as much as possible, thereby causing limitations to shearing angle and orientation, so that use is inconvenient; and 4. the fabrics leave traces on a wearer, and are uncomfortable.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 to 5, an embodiment of the present disclosure provides a comfortable breathable warp-knitted fabric free of deformation, yarn hooking and unraveling, which includes a fabric body formed by warp-knitting four strands of yarns, wherein the four strands of yarns are respectively a first yarn 1, a second yarn 2, a third yarn 3 and a fourth yarn 4. The components in this embodiment are described in detail below with reference to the accompanying drawings.

As shown in FIG. 2, the first yarn 1 stretches across three longitudinal stitch lengths and is fed alternatively to form a loop such that a warp-knitted structure formed by knitting the first yarn 1 is a closed-end satin stitch. The closed-end satin stitch can also be called a four-needle tricot stitch. The yarn feeding numerical code of the closed-end satin stitch is 1-0/3-4//. A guide bar overlaps by three stitch lengths, and underlaps by one stitch length. A loop of the stitch is a closed-end loop, which means that the extension yarns at a loop base are crossed. The closed-end satin stitch is used as a surface stitch.

As shown in FIG. 3, the second yarn 2 is alternatively fed on two adjacent needles to form a loop such that a warp-knitted structure formed by knitting the second yarn 2 is a closed-end tricot stitch. The yarn feeding numerical code of the closed-end tricot stitch is 1-0/1-2//. A loop of the stitch is a closed-end loop, which means that the extension yarns at a loop base are crossed. The closed-end tricot stitch is used as a ground stitch.

As shown in FIG. 3, the third yarn 3 is periodically inserted into the closed-end tricot stitch formed by knitting the second yarn 2 such that a warp-knitted structure formed by knitting the third yarn 3 is a weft laid-in stitch, the weft laid-in stitch formed by knitting the third yarn 3 is of a structure of one stitch length. The yarn feeding numerical code of the weft laid-in stitch formed by knitting the third yarn 3 is 0-0/1-1//.

As shown in FIG. 4, the fourth yarn 4 is periodically inserted into the closed-end tricot stitch formed by knitting the second yarn 2 such that a warp-knitted structure formed by knitting the fourth yarn 4 is a weft laid-in stitch, the weft laid-in stitch formed by knitting the fourth yarn 4 is of a structure of two stitch lengths. The yarn feeding numerical code of the weft laid-in stitch formed by knitting the fourth yarn 4 is 0-0/2-2//.

It needs to be noted here that, digits in the yarn feeding numerical code represents a sequence number of needles, every two of transverse rows are partitioned by “/”, and a complete stitch is ended with “//”.

In this embodiment, the first yarn 1 can be preferably configured as a polyarn ide yarn. Polyarn ide fiber is called Nylon. Nylon has the most prominent advantage of highest wear resistance among all fibers. The wear resistance of Nylon is 10 times that of cotton fiber and 20 times that of wool fiber. When stretched by 3-6%, Nylon has an elastic recovery ratio of up to 100%. Nylon can withstand over ten thousands of folding without breakage, and has the highest fatigue durability among all fibers.

In this embodiment, the second yarn 2 can be preferably configured as a polyurethane yarn. The third yarn 3 can be preferably configured as the polyurethane yarn. The fourth yarn 4 can be preferably configured as the polyurethane yarn. Polyurethane fiber is an abbreviation of polyurethane elastic fiber, usually referred to as PU. PU is a block copolymer with a copolymer long chain consisting of a soft segment and a hard segment. The soft segment in a fiber structure may be polyester or polyether. According to the soft segment, the polyurethane fiber can be classified into two varieties, namely polyester type and polyether type. The polyurethane fiber can usually be stretched by 400%-800%, has excellent elastic recovery performance, and has a shrinkage rate of even beyond 99% when stretched by 50%. The polyurethane fiber has high resistance to chemical reagents, for example, acids alkali, organic solvents, dry cleaning detergents, bleaching agents, etc.

Of course, yarns made of other raw materials can also be used upon actual demand, and are not limited to the yarns in this embodiment.

The fabric formed by compounding four stitches has high elasticity, has loops interlocked, and is not prone to unraveling; bottom loops are under balanced stress, capable of preventing the fabric from curling at edges; and the weft laid-in stitch has relatively low extensibility and high transverse elasticity.

In a word, the fabric of the present disclosure does not unravel during shearing, is convenient to use, does not leave traces on a wearer, and is very comfortable. The present disclosure has the advantages of being free of deformation, yarn hooking and unraveling, comfortableness, breathability, etc.

The above-mentioned embodiments are preferred embodiments of the present disclosure, but the embodiments of the present disclosure are not limited to the above-mentioned embodiments, and any other changes, modifications, substitutions, combinations and simplifications made without departing from the spirit and principle of the present disclosure should all be equivalent replacement methods and should all fall within the scope of protection of the present disclosure.
