Today we will talk about the pretreatment of coral fleece by coral fleece manufacturers. Now, Changshu Longfei Needle Textile Co., Ltd. will introduce the pretreatment of coral fleece by coral fleece manufacturers.
The whole process of coral fleece pretreatment is: at the top of the list, this process seems simple, but there must be a safety hazard. The unwinding time is tilted and recorded on the banknote.
Joints: When jointing, pay attention to the selection of each junction box cloth. It is sewing. The main reason is that it is sensitive, convenient, and fast. It has less sewing thread and is suitable for sewing between various trolleys and trolleys. However, the stitched cloth stack simply presents the shortcomings of rails like joints, when the magnetic head is not too wide, about 10 ~ 15cm.
Preservation type: pre-setting refers to the direct heat setting of the white fabric (the temperature is 190-230 degrees Celsius), so that the fabric is in a relatively stable state during the initial dyeing and finishing process. In the molding process, the fabric strength is not easy to stick, and the good hair style in the dyeing process is not easy to deform and subsequent processing and shrinkage.
The fabric is affected by the style of the fabric and is loosened and shortened by dry heat. Because of the elimination of wrinkles, the uniformity of the molecular structure has been improved. Tension must be applied to the fabric. The addition of tension will reduce the crepe effect, reduce flexibility, and deteriorate softness, resilience and fullness. In order to avoid the disappearance of the crepe effect and the influence of the fabric style, the width is generally 3 ~ 5cm wide for the predetermined product, the tension of the front car guide roller is fully relaxed, and the proper overfeeding (less than 40% of the general control) is maintained. The preset temperature is generally controlled at 165 to 200 degrees Celsius. According to the fiber heating time, heat soaking time, fiber macromolecule adjustment time and fabric cooling time to determine the aggregation time. Setting the tension only needs to reach the fabric flatness requirement, and the appearance can be ensured to avoid affecting the texture of the fabric.
When ordering the type, be careful not to drop it, tear the edge, measure the width and meter, and the weight and customer requirements should not exceed 10g. Then check the appearance of the catheter, the grid, the colorful printing, and the sticky hair. To deal with these problems, you must be serious and timely . Attention should be paid to whether the equipment is lacking, the tension, temperature, and cloth speed are suitable for control. And India just saw the air duct, the general standard is around 1500 rpm, which side should pay attention to the air resistance.
Folding: Folding, the operation is similar to the seam head, and the outer packaging used is about 3~5cm wide. Workers in the packaging process must strictly demand themselves, and it is convenient and quick to not add a marginal width. This process is primarily used for the next process to avoid the margins from being colored.
