Pre-production preparation

First, the printing and dyeing factory to play L / D sample or S / O sample sent to the customer to confirm

In the quality inspection stage of the finished product, the appearance quality of Qijingdian was carefully checked to test the physical indicators and the color fastness. The quality of finished products was well understood. Some particularly important test items must be sent to a third-party testing agency for testing. Only when satisfactory test results are obtained can the large cargo orders be decided. This is the safest approach. Some of the major brands in Europe and America that we are exposed to are basically Such a program works.

Second, the determination of billet loss

In addition to clearly defining the quality in the contracts signed with the printing and dyeing factories, it is also necessary to negotiate and determine the processing losses of the grey fabrics . This is a problem that traders need to consider when purchasing their own grey fabrics and processing at the printing and dyeing plants. It is advisable that the newly purchased grey cloths should be tested in a vanguard form in the form of a single sheet to the printing and dyeing factory to determine whether the single grey cloth can satisfy the requirements of the order processing and dyeing of the finished products, and at the same time, it is also possible to understand the actual condition of the grey fabric. Processing loss.

In determining the loss of the billet, one must understand the fabric's processing elongation, for example, Pakistan's twill fabric usually has a small elongation before processing, and the ordinary domestic plain weave fabric has a larger processing elongation; second, it is necessary to consider The size of the preshrinkage rate during finishing, the preshrinkage rate is related to the rate of change in the size of the wash; third, the difficulty in dyeing and printing of a specific product should be considered. For example, the rate of printing and dyeing, which is easy to curl, is relatively high. The long process flow, the production difficulty is much larger than the bleached cloth; Fourth, the size of the production batch, the more the production of small orders to the factory the greater the processing loss. The above factors should be integrated, and the printing and dyeing plants should be consulted together to determine a relatively reasonable and mutually acceptable billet wear rate.

Third, the determination of delivery

The general printing and dyeing factory will have a commitment on the delivery date for customers, and this time plan should be used to make necessary preparations before billing. There is a precondition for the two dyeing factories to submit this commitment, which is usually based on the customer's swatch confirmation and the customer's time for the billet to enter the factory. The trader must ensure that the customer is L/D-like. The approval or confirmation of the S/O sample does not affect the delivery date. As a trader, the documentary personnel must have a reasonable margin for the delivery date, because there may be sudden problems in the production of orders for large goods. To handle these problems, there is still a certain amount of time to influence the delivery date. The factors may be the customer's problem (for example, the customer's confirmation of the swatch is not timely), or it may be a problem with the printing and dyeing plant (for example, a sudden problem occurs in production). Gradually accumulate experience in the process of documenting to master better.
