Interpretation Of Production Technology And Management Of Japanese Advanced Ladies' Wear

In the production of women's clothing, not only the main processes, such as cutting, sewing, and ironing, need strict control and reasonable arrangement, but also some processing details, such as manual work, needle inspection procedures, stain removal and so on, need to be taken seriously, carefully operated and striving for perfection. Only by adopting scientific and reasonable technological means and enhancing the quality consciousness of all staff can we display the design works perfectly. Through the research and practice of Japanese garment enterprises, the author summarizes the main experience and characteristics of the production management of Japanese advanced ladies' clothing. Key words: advanced women's clothing production management and processing technology

5S management mode

In Japan, the 5S management mode is widely adopted by garment enterprises producing high level women's clothing. Its contents mainly include 5 steps: sorting, rectifying, cleaning, cleaning and customary.

Sorting out and rectifying

Consolidation and rectification are the foundation of production management. Equipment, accessories and auxiliary tools needed for women's clothing production should be placed, transported and used according to the requirements of product processing. Following the principle of "eye management", we can find out the breakdown of workshops at a glance, manage the number of finished products and semi finished products and the remaining orders, and emphasize highly efficient and orderly.

　　 Cleaning and cleaning

The quality of an enterprise reflects not only the management level of an enterprise, but also the important guarantee of product quality. For example, many Japanese clothing companies such as Japan Spring Fiber Co., Ltd. use white cloth or paper every day to check whether the sewing equipment is clean, not only requires cleaning of production environment, production equipment and auxiliary tools, but also requires employees to pay attention to their cleanliness and hygiene. This will not only enable enterprises to have a beautiful and clean environment, high-quality products, but also leave a good impression on customers, so as to continuously improve the economic efficiency of enterprises.

　　 Habit

Once decisions have been made, they should be observed and practiced. They should develop good working habits, be civilized and courteous, and be able to meet each other among employees, employees and leaders.

Exquisite women's clothing processing technology

We are Japan During the training, the first thing to learn is the production process of women's clothing. From the beginning, we practiced sewing straight lines, arcs to later assembly line operation and the whole production of women's garments. The stitched garments were soft and beautiful, with little error in size and template. These are difficult for some women's clothing processing enterprises in China to achieve.

The characteristics of advanced women's clothing are low volume and variety. Therefore, the arrangement of production lines is quite different from that of women's clothing enterprises in China. The production of advanced women's clothing is usually done by semi-automatic hanging production system. A hanger hangs on the same garment according to certain rules, and each coat hanger is marked with serial numbers. Thus, although hanging time is slightly time-consuming, the whole production management has more advantages than disadvantages. First, it can reduce the land occupation, facilitate the fetching, and circulate quickly. Secondly, it can avoid chromatic aberration. Thirdly, the front and back processes supervise and help each other, which not only improves the output, but also ensures the quality of the product.

　 The specific production process has the following characteristics:

Preparation before production

I. inspection, testing and sorting of excipients

　　 Fabric (including some excipients) before being cut, they are all heat shrinkable and stereotyped. The heat shrinkable process ensures that the size of the garments is stable, and the finalization of the fabric can be adjusted to the warp and weft yarn of the fabric. Therefore, different types of fabrics with different thickness and thickness can be processed on the same sewing equipment, which is simple and convenient, thereby reducing the wear and tear caused by the debugging machine. In addition, the fabrics made of heat shrinkable and stereotyped fabrics can be directly cut, without loosening cloth for a long time, so as to reduce the wrinkling of cloth pile pressure, thereby saving the cutting time (usually 24 /8 hours).

　　 Two. Process analysis

The role and importance of process analysis

Process is the smallest unit of operation series. Process analysis refers to the decomposition of all operations in the process of making basic materials into finished products, defining the nature of operations, sequence, equipment and time consumed in each processing step, so as to effectively use labor and equipment to ensure that products are processed at the fastest and lowest cost.

The content, order, time and tools and equipment needed for product processing should be defined to make the production orderly and convenient for production guidance and management.

　　 working procedure Analytical charts or process charts can be used as basic materials for process planning, production planning and scheduling, which is conducive to balancing production lines.

Find out the shortage of the production line design, further improve the process organization and continuously improve the production efficiency.

(two) process balancing

Process balancing is the key content and the most difficult part of process analysis. Managers should conduct careful and careful analysis and study according to the specific conditions of products, equipment and staff, so as to make the production line smooth and fast. The following tasks must be done:

The average processing time of each process of the assembly line is calculated scientifically and reasonably, for example, the standard jacket is 3 minutes. At the same time, 3 hangers (i.e. 3 semi finished products) should be kept equal in each process.

According to the technical condition of the workers, the process arrangement is adjusted. The technical expertise and comprehensive quality of the workers are mainly considered here. If some workers are suitable for the preceding process, they can not be arranged in the post process; while some workers are not comprehensive in technology, they should avoid arranging in the difficult technological process. Employees sometimes suffer from illness, absence, absence, and so on. At the same time, they should make appropriate adjustments, otherwise the pipeline will stop blocking.

Timely adjustment of sub healthy flow production. The "sub-health" referred to here is that the surface of the entire pipeline looks smoother. In fact, the phenomenon of output decline often occurs. The main reason is that the speed of each process slows down. At this point, it is necessary to adjust the speed of one key process to change the situation and speed up the whole pipeline.

　 Equipped with a fully skilled mobile workforce as a "balance" for balancing production lines.

Cutting technology

The tailoring project is the first step in the formal production of garments. It cuts all kinds of garment fabrics into various garment pieces according to the garment models to be put into production, and provides tailoring for the sewing process, including the formulation, layout, paving and cutting of cutting plans. The quality of cutting sometimes affects not only one or two costumes, but also the number of garment pieces, which is directly related to the economic benefits of enterprises.

First, accurate and quick clipping.

In Japan, the automatic cutting system is commonly used in the production of advanced women's clothing. It is made up of computer control center and special tailoring bed. The cutting piece has high accuracy and can reduce the labor intensity of workers. To avoid manual cutting of the first and last layers of the size of the error, cutting knife eye and line can be consistent with the template on the layout. It is accurate and fast, and is especially suitable for women's clothing production of many varieties and fewer batches.

Two. Paving Technology

When laying materials, we must follow certain technological requirements and not arbitrarily disassemble. The key is to determine the length and number of layers. In addition, attention should also be paid to the details of cloth leveling, selvage alignment, pressure reduction and fabric orientation. In order to make the silk thread straight and the fabric of the first layer consistent with the specifications of the last layer, the team members must work in concert and cooperate with each other. It is necessary to use special long needles, fixed before the cutting table, and then pass through the same pattern at each layer, so that special materials can be cut into single or several pieces to ensure the design and process requirements.

Bonding technology

The adhesion between the fabric and the interlining can make the garment piece form the shape that is consistent with the human body, so that the collar, cuffs, waist head and other parts have the appropriate stiffness and elasticity, increase the strength of buttons, knobs, and so on, and improve the seams of garments. The bonding process is mostly carried out on the bonding machine, and the temperature, pressure and time should be paid attention to.

This is a necessary and important process in the processing of advanced women's clothing in Japan. Before the adhesion, the production template must be painted on white paper, and then the slice should be normalized according to the drawing pattern. It avoids the phenomenon that the traditional bonding process often produces the skew of the chip or the shape of the sample.

　 Sewing technology

First, drawing process template.

This process is to directly draw the process template (with Mark pen or pencil) on the white cloth on the ironing stand, then check and adjust all the cutting pieces and the ironing plate pattern that have been bonded by the adhesive machine. If the cutting piece is too small or too large, the amount of the seam can be adjusted to meet the requirements of the size of the garment, but it must be within the prescribed limits (not less than 0.7cm of the general seam).

Two, point position, hot band.

When the garment piece coincides with the pattern plate, the special parts are used for the next part of the process and combined with all kinds of linings and belts, according to the process.
