Description

Technical Field

[0001] The utility model relates to the field of antistatic textiles, in particular to a ribbed elastic fabric used for antistatic cuffs, collars and hems of clothes in a dry environment. Background Art

[0002] Most people have experienced static electricity in their bodies, which has caused an unpleasant electric shock feeling to a greater or lesser extent. When the human body wears chemical fiber clothes, and in dry winter and indoors, all kinds of clothes will generate static electricity to a greater or lesser extent. When static electricity accumulates to a certain amount, it will be discharged through a certain outlet. For example, when you touch the door handle, the discharge will produce an electric shock feeling, and when you take off your clothes, there will be obvious spark-like discharge. In life, if you are not careful, static electricity will visit, which will make people feel scared. Therefore, it is necessary to release static electricity in time without causing serious discharge consequences.

[0003] There are several ways to achieve this effect: one is to wear clothes containing anti-static fibers to eliminate static electricity at any time; the second is to increase the humidity in a dry environment; the third is to wear an anti-static bracelet. Even so, static electricity can still be discharged through the palm of the hand and cause electric shock.

[0004] The cuffs, collars and hems of clothes are mostly made of rib knitted fabrics, which have good shedding, curling and extensibility, and also have great elasticity. Rib knitted fabrics are knitted fabrics formed by a yarn in longitudinal rows of coils on the front and back sides in sequence. When making rib fabrics, chemical fiber DTY filaments or cotton yarns or polyester-cotton blended yarns are generally used. In order to improve the elasticity, elastic yarns are usually added, such as spandex elastic yarns, polyester elastic yarns or nylon elastic yarns. Among them, polyester or nylon elastic yarns are self-curling elastic yarns made by composite spinning of two raw materials with different properties.

[0005] Rib fabrics can be used for collars, cuffs, trouser legs, hems, socks, close-fitting or tight-fitting stretch shirts, etc. Rib fabrics can be woven on rib machines, double-sided jacquard machines, double-sided multi-needle machines, and flat knitting machines. Among them, flat knitting machines are used for sheet-shaped rib fabrics, and circular knitting machines are used for cylindrical rib fabrics. Summary of the invention

[0006] In order to solve the problem of electric shock caused by accidental discharge of a large amount of static electricity through the palms and other parts of the body, a highly efficient anti-static rib fabric is provided.

[0007] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by the utility model is: a high-efficiency anti-static rib fabric, characterized in that it includes a conductive elastic yarn as a face yarn and a polyester low-elastic yarn as a bottom yarn, the conductive elastic yarn is completely covered on one side of the polyester low-elastic yarn, the conductive elastic yarn and the polyester low-elastic yarn are fed together into a weft knitting machine to form a loop and woven into a rib fabric, and only the conductive elastic yarn is exposed on the surface of the rib fabric.

[0008] Preferably, the fiber density of the conductive elastic yarn is less than 50% of the fiber density of the polyester low-elastic yarn.

[0009] Preferably, the content of the conductive elastic yarn in the fabric is 25%-35%.

[0010] Preferably, the content of the conductive elastic yarn in the fabric is 30%.

[0011] Preferably, the conductive stretch yarn is a porous carbon black conductive POY yarn produced by a composite spinning process, and the conductive DTY yarn is produced by a stretching process, and its resistivity is less than 20Ω.cm. POY: pre-oriented yarn, DTY: stretched textured yarn.

[0012] Preferably, the conductive stretch yarn is a porous metal oxide type white conductive POY yarn produced by a composite spinning process, and the conductive DTY yarn obtained by the stretching process has a resistivity of less than 2000Ω.cm.

[0013] Preferably, the conductive stretch yarn is a conductive DTY composite yarn obtained by blending polyester-based or nylon-based POY filaments and conductive POY filament networks and then stretching them.

[0014] Preferably: the high-efficiency antistatic rib fabric is mainly used for clothes to prevent static electricity and electric shock, and the rib fabric is the cuff of clothes to prevent static electricity and electric shock.

[0015] Preferably, the ribbed fabric is a collar of clothes that prevents static electricity and electric shock.

[0016] Preferably: the ribbed fabric is a hem of clothes that prevents static electric shock.

[0017] In the above scheme, the strength of the conductive elastic yarn is below 3cN / dtex, the strength of the polyester low-elastic yarn is above 4.5cN / dtex, and the content of the conductive elastic yarn in the fabric is about one third, which not only ensures the transverse and longitudinal strength of the fabric, but also ensures the conductive effect of the fabric.

[0018] The high-efficiency antistatic ribbed fabric also includes a coloring process according to the fabric color tone requirements.

[0019] Compared with the traditional structure, the utility model has the following beneficial effects:

[0020] 1. In dry winter or heated indoors, even clothes made of natural fibers such as wool and cotton will generate a lot of static electricity when the humidity is very low, and it is inevitable that discharge will occur through the palms and other parts to cause electric shock. The use of the utility model can more conveniently avoid electric shock at all times, which is convenient and practical.

[0021] 2. The ribbed fabric of the utility model adopts high molecular conductive fiber, especially elastic yarn, which is similar to the common clothing fiber material and will not produce strange feeling. Wearing the clothes can protect against electric shock. Compared with the anti-static bracelet, electric shock will not occur due to forgetting to wear it.

[0022] 3. The utility model adopts carbon black organic conductive fiber obtained by composite spinning, which has the characteristics of corona discharge and can discharge by non-contact discharge; at the same time, the high content of conductive fiber greatly improves the discharge efficiency.
