Embodiment 1

[0092] The method is to detect the flatness of hem appearance sewing for a standard sample or a self-made sample, the detection data of the standard sample is stored in the standard database and called, and the detection data of the self-made sample and the parameters of the corresponding object in the standard database Carry out analysis and comparison, and then analyze and process to give the sewing process parameters of the specified product;

[0093] The method comprises the steps of:

[0094] Step 1: Sample Selection

[0095] Select a standard sample that is a product that has been evaluated by an authoritative institution, or,

[0096] Select a piece of fabric with a specified size, and the sewing worker completes the specified self-rolling sewing on the specified sewing machine according to the specified process requirements to form a self-made sample;

[0097] Step 2: The sample is left in a standard room for 24 hours; in this embodiment, the temperature in the stand...

Embodiment 2

[0128] Basically the same as Example 1, the difference is: the calculation method of the actual curved surface area SA of the sample is SA=S 1 +S 2 +…+S k； The calculation method of the projected area SB of the sample is SB=S 1 cosθ 1+S 2 cosθ 2 +…+S k cosθ k .

Embodiment 3，4

[0130] They are basically the same as Embodiments 1 and 2, except that the Handyscan 3D series hand-held self-positioning 3D laser scanner and its software developed by Creaform Company are used in the 3D scanning process.

Abstract

The invention discloses an intelligent formulating method for sewing process parameters of a turned edge of a lower hem of a woven fabric. According to the method, the sewing flatness of the appearance of lower hems of standard or self-made samples is tested, test data of the standard samples is stored in a standard database for calling, test data of the self-made samples is compared with parameters of a corresponding object in the standard database, process parameters are adjusted if necessary and then tested, and finally the reasonable sewing process parameters are obtained; a computer is used for three dimension scanning and data processing on the standard or self-made samples in the detection process to solve characterization parameters; the test data of the standard samples is saved in the standard database for latter use; the self-made samples are compared with the corresponding woven fabric in a standard library to determine whether or not the self-made samples are qualified, ifthe self-made samples are qualified, the corresponding process parameters are output; if the self-made samples are not qualified, the process parameters are adjusted and the previous detection is repeated until the self-made samples are qualified. The method is scientific and reasonable, simple and easy to operate, high in intelligence and high in work efficiency.

Description

technical field [0001] The invention relates to an intelligent formulation method of process parameters for hem curling of woven fabrics in the garment industry. Background technique [0002] In the garment industry, the primary problem affecting the quality of woven fabrics is the smoothness of the garment appearance after sewing. To solve this primary problem, it is necessary to formulate scientific sewing process parameters. The key process parameters mainly include: sewing density, sewing Thread tension and presser foot pressure are three major factors. At present, the mainstream method of formulating process parameters is: process technicians can achieve ideal results through many times of trial and trial production according to their own personal experience. Its shortcomings: high requirements for experience level, greatly influenced by subjective will, long trial and error cycle, and low efficiency. Contents of the invention [0003] The purpose of the present inv...
