Embodiment 1

[0008] Cow leather leftovers are used as raw materials, and collagen fiber bundles are produced through a leather fiber production line. Using it as a raw material, it is uniformly pre-wetted by spraying water, and the pre-wetted collagen fiber bundles are put into water-based polyurethane. Soak in the barrel of the emulsion, add a proper amount of penetrating agent in order to speed up the soaking, take out the soaked collagen fiber material and send it to the roller extruder for extrusion, squeeze out the excess adhesive and send it to the oven for drying. The temperature is controlled at 50-60 degrees Celsius, and the fan is used to circulate strongly in the box and the wet water vapor is discharged from the steam outlet above the box. Heating adopts far-infrared heating method. When the fiber is dried to a water content of about 15%, it can be discharged. After drying, the collagen fiber bundle is made into a single collagen fiber bundle by an opening machine. As a non-wov...

Embodiment 2

[0010] This example uses the same materials and basically the same process as the previous example, the difference is that the water-based polyurethane adhesive is changed to polyvinyl alcohol adhesive, and the raw materials after the same process as the previous example are used to produce For non-woven fabrics or textiles, the finished product needs to be debonded with hot water to remove the polyvinyl alcohol, that is, the polyvinyl alcohol in the collagen fiber product is removed, and the pure collagen fiber regenerated leather product without the adhesive is formed. .

Abstract

The invention provides a modification method of collagen fiber bundles. The collagen fiber bundles are dipped into aqueous binders and then are dried, carding and opening are carried out, and the collagen fiber bundles can become a novel fiber material capable of being used for non-woven and woven technology.

Description

(1) Technical field [0001] The invention belongs to the field of collagen fibers, and in particular relates to a modification method for impregnating adhesives to reinforce collagen fiber bundles. (2) Background technology [0002] The collagen fiber bundle belongs to a new kind in the protein fiber, and the collagen fiber bundle of the present invention refers to a kind of tanned leather collagen fiber bundle. It is mainly taken from the dermis of animals. It consists of protofibrils (1.2-1.7nm in diameter) to form fiber bundles (20-150nm in diameter) step by step. The thicker fiber bundles are sometimes divided into several thinner fiber bundles, and these thinner fiber bundles are sometimes combined with other thin fiber bundles to form another larger fiber bundle, so that they are constantly separated and combined, combined and separated again, A special three-dimensional network structure is formed vertically and horizontally. Therefore, it is a very difficult technol...
