Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of fabric, especially relates to a geometric three -dimensional cutting woven fabric. BACKGROUND

[0002] The traditional fabric on the current market usually adopts symmetrical weaving sequence, which is characterized by arranging yarns in uniform and regular order. Although this weaving method can ensure the basic structural stability and uniformity of the fabric, it also has many shortcomings. First, the fabric lacks three-dimensionality and gradation, and the symmetrical weaving sequence leads to a flat surface of the fabric, making it difficult to form complex geometric patterns or three-dimensional shapes, which limits the creative expression of design. Secondly, due to the uniformity of yarn arrangement and tension distribution, the elasticity and softness of the fabric are relatively single, which cannot meet the specific comfort requirements. In addition, this weaving method exhibits consistent ductility when subjected to stress in different directions, but in some cases where local reinforcement or weakening of elasticity is required, this consistency becomes a disadvantage, and the fabric is prone to structural fatigue or local deformation during use. In order to solve these problems, conventional methods include adding reinforcing materials in the post-processing, using multi-layer fabric splicing, or adjusting the pattern and cutting in the design stage. However, these methods often have new drawbacks, such as the introduction of reinforcing materials which may increase the overall weight of the fabric, affecting the wearing comfort; multi-layer fabric splicing increases the manufacturing cost and is prone to a heavy or uncomfortable feeling at the joint; and adjusting the pattern and cutting to compensate for the shortcomings of the weaving method can only improve the problem to a certain extent and cannot fundamentally solve the problem of lack of three-dimensionality or single elasticity distribution of the fabric.

[0015] Viscose nylon yarn is a mixed yarn made of viscose fiber and nylon fiber.

[0016] The elastic modulus of the high-elasticity soft viscose nylon yarn is between 10-15 GPa.

[0017] The three-dimensional cutting pattern of the fabric is formed by the connection of specific knitting points and knitting lines formed by the unequal arrangement weaving method, ensuring the stability and support of the fabric in different directions.

[0018] The unequal priority arrangement weaving method forms a fabric surface with high three-dimensionality by adjusting the tension and knitting angle of the yarn.

[0019] Unequal knitting sequence refers to the arrangement and knitting of yarn in an asymmetric order and tension during the knitting process, forming unique patterns and three-dimensional structures. This asymmetry can be reflected in the arrangement of yarn, knitting density, tension changes, etc.

[0020] Asymmetric arrangement: Yarn is not arranged in a uniform and symmetric manner, but asymmetrically according to design requirements.

[0025] According to the design drawings and three-dimensional modeling requirements, determine the specific scheme of the unequal knitting sequence.

[0026] Use computer-aided design (CAD) technology to simulate the knitting process and optimize the arrangement and tension changes of the unequal sequence.

[0027] Basic knitting: Use high-elasticity soft viscose nylon yarn and arrange it in a 2-by-2 rib pattern for basic knitting.

[0028] Unequal arrangement: According to the design scheme, adjust the arrangement order of the yarn during the knitting process, and use the unequal priority arrangement method.

[0029] Tension control: By adjusting the tension of the yarn, different tight and loose knitting sections are formed to enhance the three-dimensional effect.

[0030] Density adjustment: Use different knitting densities in different areas to form the required three-dimensional patterns and structures.

[0031] Check the overall effect of the knitted fabric to ensure that the unequal knitting sequence forms the expected three-dimensional pattern and pattern.

[0032] Adjust and correct any part that does not meet the design requirements, ensure the quality and consistency of the final fabric.

[0062] Elasticity and Softness Detection of the Above Fabric:

[0063] 1. Elasticity Detection

[0064] Detection Equipment: Electronic Universal Testing Machine

[0065] Detection Steps:

[0066] Fix the sample on the electronic universal testing machine, with the initial distance between the clamps set to 10 cm. Stretch the sample at a speed of 5 mm / min until it breaks.

[0067] Record the maximum stretching length, breaking point, and stretching force of the sample.

[0068] Data Record:

[0069] Initial Length: 10 cm

[0070] Maximum Stretching Length: 18 cm

[0071] Maximum Stretching Force: 15 N

[0072] Calculation Formula:

[0073] Elastic Modulus = (Maximum Stretching Force) / (Maximum Stretching Length - Initial Length)

[0074] Calculation result: Elastic modulus = 15 N / (18 cm - 10 cm) = 1.875 N / cm

[0075] 2. Softness detection

[0076] Detection equipment: Fabric softness tester

[0077] Detection steps:

[0078] Place the sample on the test platform of the fabric softness tester.

[0079] Start the tester and record the bending angle and recovery force of the sample under a certain pressure.

[0080] During the test, each sample is measured 3 times and the average value is taken.

[0081] Data record:

[0082] Test pressure: 1 N

[0083] Bending angle: 60°

[0084] Recovery force: 1.2 N

[0085] Calculation formula:

[0086] Softness index = Recovery force / Bending angle

[0087] Calculation result: Softness index = 1.2 N / 60° = 0.02 N / °

[0088] Detection results

[0089] Through the above detection method, the elasticity and softness of the fabric using the unequal priority arrangement weaving method are tested in detail. The detection results are as follows:

[0090] Elasticity:

[0091] Initial length: 10 cm

[0092] Maximum stretching length: 18 cm

[0093] Maximum stretching force: 15 N

[0094] Elastic modulus: 1.875 N / cm

[0095] Softness:

[0096] Test pressure: 1 N

[0099] Softness index: 0.02 N / °

[0100] From the above, the fabric with unequal priority arrangement weaving method performs excellently in elasticity and softness. Its elastic modulus is 1.875 N / cm, and the softness index is 0.02 N / °. Compared with the traditional symmetrical weaving sequence fabric, the fabric shows better elasticity and softness under the maximum stretching length and bending angle. This is mainly due to the unique structure design of the unequal priority arrangement weaving method, which makes the tension and arrangement of the yarn more reasonable in different areas, improves the three-dimensional feeling and comfort of the fabric. Through this innovative weaving process, the fabric can better meet the high requirements of modern clothing design for individualization and functionality.
