Bundling method of synthetic fiber bundle and synthetic fiber bundle

Abstract

PURPOSE: To provide a method of packing synthetic fiber bundles wherein curls (cold-setting) occurring during packing and transportation can be minimized to prevent workability and cosmetic characteristics from degrading, and to provide a synthetic fiber bundle for a wig. CONSTITUTION: The method comprises a step of packing the synthetic fiber bundles in a circle with a radius of curvature of 35 mm or more when casing the bundles. The synthetic fiber bundle has an average weaving degree of a single fiber in the bundle of 35 to 85 dtex, and a coefficient of a curl of the fiber when cut for use is 0.25 or less.

Description

technical field [0001] The present invention relates to synthetic fiber bundles used as raw materials for various wigs (wigs, hairpieces, toupees, lesson wigs, etc.) and packaging thereof The method, in more detail, relates to a fiber bundle and a packing method thereof that minimize wrinkles (coldset at room temperature) that occur during packing transport. Background technique [0002] In the past, the delivery form of synthetic fibers used as raw materials for wig products was generally packed in boxes. The fibers used in this product are modified acrylic fibers, polyvinyl chloride fibers, polyester fibers, polypropylene fibers, etc., and when stored in a box, there are large wrinkles that will cause the bundled product bundles to form wrinkles. shortcoming. In addition, since the thickness of fibers for such applications is usually 35 to 85 decitex (dtex), which is close to the thickness of human hair, once creases are formed, they cannot easily recover. As another pa...

Problems solved by technology

However, when fiber bundles are usually packaged in boxes, not only large curvatures but also small curvatures occur at the corners of the boxes or due to confusion during packaging, resulting in wrinkles.

If such wrinkled parts are mixed in the raw material to be processed, the hair flow in the hair bundle will be disturbed, and when it is placed on the sewing machine, it will become a cause of great confusion in the feeding of the hair. Trimming will significantly reduce the work efficiency, and the uniformity of the hair flow or thickness of the produced cape-shaped hair will also be impaired. The wrinkle can be partially alleviated by rolling it on an aluminum tube for heat setting. , but it is impossible to completely remove the wrinkles, and it is easy to produce fatal quality defects for straight hair wigs characterized by the straightness of the hair flow

In addition, even if it is a curly wig, the hair is not neat when rolled on the tube, so it is time-consuming, and the designed outline cannot be seen due to messy or poor uniformity of the hair after removing the finished product. In addition, it will make it difficult for a brush or comb to comb through, etc., so that the cosmetic properties are impaired

[0004] Wrinkles of fiber bundles that impair processability and cosmetic properties usually account for a few percent of the length, and in many cases, it can be as high as 10% or more. In addition to low operating efficiency and unstable quality in the processing process, the yield of raw materials will also decrease, which is a big problem
