Abstract

The invention belongs to the technical field of clothing processing, in particular to a down-drilling-preventing sewing process of a spliced down jacket, which comprises the following steps of calculating a front chest saving amount delta F and a back saving amount delta B according to a formula, and scribing and cutting a front piece and a back piece of a fabric spliced cut piece according to the front chest saving amount delta F and the back saving amount delta B respectively; aligning the fabric splicing cut pieces and the down liner cut pieces at the same position, inwards folding the splicing edges, dispensing and fixing the splicing edges, quilting the aligned fabric splicing cut pieces and the down liner cut pieces into bins according to designed bin dividing lines, filling quantitative down into each independent bin through a down filling machine through a down filling opening reserved on the down liner cut pieces, and sewing the down filling openings to obtain the ready-made garment. When the down jacket is manufactured by splicing the fabrics with different thicknesses, the down jacket can still ensure good down penetration resistance.

Description

Anti-penetration down sewing technology of spliced down jacket Technical Field The invention belongs to the technical field of clothing processing, and particularly relates to a down penetration-proof sewing process of a spliced down jacket. Background The spliced down jacket is winter clothing designed by combining different materials, colors or functional modules, common down is combined with materials such as polar fleece, wool, jean and the like, for example, a front piece is filled with the down for keeping warm, and a cuff or a back is used for improving skin feeling by using the polar fleece. The spliced down jacket has practicability and aesthetic feeling, and is a mainstream product in the market due to novel style and strong stereoscopic impression. The existing sewing technology of the spliced down jacket has the defects that gaps of seam lines are too large due to lamination of fabrics at the spliced positions, down is easy to drill out from the seam holes, common cotton threads are adopted as traditional seams, the seam holes are expanded after washing to exacerbate down drilling, scientific and energy-saving distribution is lacked in layout design during splicing, the problems of unbalanced front and back bodies, oblique thread locks and the like are easy to occur, part of technology relies on iron buckle ironing and bonding lining to consume energy, the fabrics are burnt and Mao Lou are possibly caused, and down liner layers are penetrated during buckle installation, so that down running risk is further increased. Through retrieval, the patent of publication number CN114468438B discloses a prototype garment design method, which comprises the steps of firstly obtaining torso body surface data, then obtaining zero-looseness data according to the torso body surface data, obtaining dimension conversion data according to the torso body surface data, wherein the dimension conversion data are used for indicating a basic size of a template, the chest and province (XSS) =x/13.3+2.6, the gear difference is 0.3, the scapula and province (XJJG) =x/13.3+6, and the gear difference is 0.3, then obtaining a reference curve according to the torso body surface data, the zero-looseness data and the dimension conversion data, wherein the zero-looseness data are used for indicating the basic size of the template, and finally constructing a garment template according to the zero-looseness data, the dimension conversion data and the reference curve. The prototype can intuitively reflect the relation between the human body essence and the clothing structure based on the minimum outer surrounding of the human body trunk, defines the chest province and the scapula province, enables the clothing to be more fit with the human body curve, and improves the comfort level of the clothing. However, the method does not consider the influence of the thickness of the fabric on the quantity saving, the fabrics with different thicknesses are cut by adopting the same provincial line and then spliced, the stress concentration is easy to be caused at the splice, and the velvet drilling is easy to occur. Disclosure of Invention The invention aims to provide a down penetration preventing sewing process of a spliced down jacket, which aims to solve the problems in the background technology. The down penetration-proof sewing process for the spliced down jacket comprises the following specific steps: Calculating a front chest saving amount delta F and a back saving amount delta B according to a formula, and scribing and cutting a front piece and a back piece of the material splicing cut piece according to the front chest saving amount delta F and the back saving amount delta B respectively: ΔF=k1B+k2h; Wherein DeltaF is the front chest saving, k 1 is the contribution coefficient of the down liner cut-off chest circumference to the front chest saving, B is the down liner cut-off chest circumference, k 2 is the contribution coefficient of the down liner cut-off chest height to the front chest saving, and h is the down liner cut-off chest height; ΔB=k3B+k4L+2; Wherein delta B is the back province, k 3 is the contribution coefficient of the down liner cut-off chest circumference to the back province, B is the down liner cut-off chest circumference, k 4 is the contribution coefficient of the down liner cut-off back length to the back province, and L is the down liner cut-off back length; Aligning the fabric spliced cut pieces and the down liner cut pieces at the same position, inwards folding the spliced edges, and dispensing and fixing the spliced edges; according to the designed dividing line, the aligned fabric spliced cut pieces and the aligned down liner cut pieces are quilted into dividing bins; filling quantitative down into each independent small bin through a down filling opening reserved on the down liner cut piece by using a down filling machine; and sewing the down filling opening, and assembling to obtain the ready-made garment.
