Problems solved by technology

Ordinary RSJ knitted fabrics are easily detached by external forces (including washing, pulling, etc.) in the reverse knitting direction, while the current RSJ fabrics usually improve the detachment resistance by increasing the longitudinal upper density and finished product density during weaving, but This method greatly increases the cost of RSJ fabric, and cannot fully realize the function of free cutting

Embodiment approach 1

[0016] Embodiment 1 of the present invention adopts the wrapping yarn forming method containing dry-spun spandex, and its characteristics include:

[0017] 1. Synthesize a wrapped yarn containing dry-spun spandex instead of conventional loop-forming raw materials.

[0018] 2. Make the wrapping yarn raw material containing dry-spun spandex through a special warping method to make a warp beam with uniform draft ratio of single yarn.

[0019] 3. Use the RSJ warp knitting machine to form a specific anti-loosening structure, that is, a warp yarn is alternately looped in multiple wales, and the loops are fully retracted and compacted in the warp and weft directions.

[0020] The present invention requires that the fabric courses can be tightly interwoven, and the dry-spun spandex wrapped yarn satisfies the requirement of the present invention well. Dry-spun spandex wrapping yarn uses super-elastic dry-spun spandex yarn as the yarn core, and is wrapped with a filament or short fiber...

Embodiment approach 2

[0026] Embodiment 2 of the present invention adopts the method of Jacquard double-threaded ultra-fine dry spinning naked ammonia and another kind of loop-forming raw material yarn to make a loop structure, and its technical characteristics include:

[0027] 1. On the basis of the original warp let-off of the RSJ warp knitting machine, another set of warp let-off is installed, which is located at the front end of the Jacquard warp let-off (not from the front and back of the two Jacquard combs according to the existing design). pinhole), which facilitates the elastic yarn to pass through the two jacquard guide pinholes from the front of the guide comb. The biggest advantage of threading yarn in this way is to fully consider the situation that the elastic yarn is prone to sticking and knotting during the starting process, and it is as convenient as possible for the staff to troubleshoot the yarn failure.

[0028] 2. A new set of independent yarn running system suitable for ultra-...

Abstract

The invention provides a free-cutting fabric weaving method based on an RSJ warp knitting machine. The method comprises the steps that one or more types of yarns which comprise dry-spun spandex fasciated yarns or superfine dry-spun naked ammonia are provided; the dry-spun spandex fasciated yarn or the superfine dry-spun naked ammonia are warped to obtain a warp beam pan head with the consistent single yarn draw ratio, bobbins with the consistent weight are screened by adopting a weighing method for warping, the weight deviation rate is controlled within 3%, and the deviation of tension up anddown is controlled within 1cN in the warping process; and the two kinds of yarns, namely the dry-spun spandex fasciated yarn or superfine dry-spun naked ammonia which is twin-threaded in jacquard combyarn guide needle holes and another kind of looping raw material yarns are fed into the jacquard comb yarn guide needle holes of the RSJ warp knitting machine to form a straight-chain, warp-plain andwarp-velvet mixed ground organization structure. The RSJ fabric obtained by the method has good anti-raveling performance, reduces the longitudinal weaving density, increases the elasticity, does notlose the hand feeling, and does not generate adverse effects on the appearance.

Description

technical field [0001] The invention relates to a method for manufacturing a free-cut warp knitted fabric based on an RSJ warp knitting machine. Background technique [0002] Unlike the multi-bar raschel machine with more than 18 flower bars, the jacquard machine consists of only a few bars and a jacquard device. Among them, the RSJ series jacquard warp knitting machine is widely used in the production of various warp knitting pattern fabrics because of its new Piaizhou jacquard jacquard system and its excellent performance. The use of RSJ fabrics in various aspects such as clothing fabrics, decorative materials, and industrial materials is increasing day by day, and the development and market application of RSJ fabrics are also changing with each passing day. Ordinary RSJ knitted fabrics are easy to fall apart under the action of external force (including washing, pulling, etc.) This method greatly increases the cost of the RSJ fabric, and cannot fully realize the functio...
