Warp-Inserted Warp Knitted Chain Structure for Bale Net Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warp-knitted looped chain structures in baling nets weaken fiber strength due to looping, leading to reduced bearing capacity without a viable solution to enhance overall structural strength without increasing fiber strength or increasing production costs.
Innovation Solution
A warp-inserted warp knitted chain structure is formed by combining a warp-knitted chain and a plain, straight insertion warp, where the insertion warp is alternately threaded up and down in the loop links, optimizing the tex ratio of looping fibers to insertion warp fibers to maximize strength while maintaining constant fineness, and incorporating connecting knots for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If warp-knitted looped chain structure is used to form baling net, then the net structure is knotless and manufacturing efficiency is high, but the fiber strength is weakened due to looping
Solution Approach 1:
The warp chain is segmented into two functional parts: looping fibers that form the knitted loop structure and straight insertion warps that run through the loops. This segmentation allows the looping fibers to provide structural form while the straight insertion warps maintain full fiber strength without bending, thus resolving the contradiction between knotless manufacturing and strength retention
Solution Approach 2:
The invention creates a composite structure combining looping fibers and straight insertion warps within the same warp chain. The looping fibers provide the knitted framework while the straight insertion warps contribute high-strength linear elements, achieving both knotless construction and enhanced overall strength
2Reliability
If the strength of insertion yarns is increased to prevent bale scattering after wefts break, then the function of preventing bale scattering is improved, but the weight and production cost of the baling net greatly increase
Solution Approach 1:
The straight insertion warps perform dual functions: they maintain structural integrity during normal operation and automatically prevent bale scattering when wefts break. This self-service capability eliminates the need for separate high-strength backup yarns, reducing overall material usage and cost while maintaining reliability

AI summary
The present invention discloses a warp-inserted warp chain knitted chain structure for knitted net and a bale net using the same, belonging to the field of knitted net structures. The warp-inserted warp chain knitted chain structure for the knitted net provided by the present invention is formed by combining two parts, i.e., a warp-knitted chain and an insertion warp plainly and straightly inserted into the warp-knitted chain. The warp-knitted chain is formed by serially connecting loop links formed through warp knitting of looping fibers. The denier of the warp-knitted chain is 3 times the denier A of the looping fibers. The ratio of the denier A of the looping fibers to the denier C of the insertion warp is less than or equal to 2.33. The present invention further discloses a bale net using the warp-inserted warp chain knitted chain structure for the knitted net. Compared with the existing warp-knitted looped chain structure, under the same knitted chain denier, the plain and straight insertion warp and the warp-knitted chain are used to jointly bear the warp load, such that the insertion warp does not have the problems of bending and weakened strength, and the strength of the knitted chain is improved, thus improving the overall strength of the bale net with the warp-inserted warp chain knitted chain structure.
