Problems solved by technology

Because collagen fibers are not resistant to long-term alkali treatment, swelling and softening treatment in alkaline solution of cowhide may have a great impact on the physical and mechanical properties of cowhide collagen fibers; swelling and softening treatment of cowhide in a solution containing only penetrant , it will lead to poor penetration and softening effect of leather, and it is easy to cause greater damage to fibers when using the fiber opening device later
[0006] In addition, the fiber opening device used in the preparation method of cowhide collagen fibers basically uses non-professional equipment to perform strong physical blows, the fiber damage is too large, and the fiber opening rate is not high, resulting in shorter length of cowhide collagen fibers and higher linear density. It can only be used in woolen style, resulting in the quality of the final fiber not meeting the raw material requirements for textile and clothing
[0007] Therefore, the cowhide collagen fiber developed by the prior art can not make full use of its properties and functions, resulting in low added value of the product

preparation example Construction

[0055] The invention provides a method for preparing cowhide collagen fibers. The preparation method comprises firstly softening the cowhide leather, then unrelaxing the softened cowhide to obtain cowhide collagen fiber bundles, and then subjecting the cowhide collagen fiber bundles to an opening process. Finally, the step of obtaining cowhide collagen fibers; wherein the softening treatment includes the step of stirring and spinning the cowhide while soaking in water; the opening treatment includes the step of using elastic materials to loosen the cowhide collagen fiber bundles. The cowhide collagen fiber prepared by this method has a fiber-making rate as high as 60% to 90%, has excellent physical and mechanical properties, and has excellent antibacterial and deodorant, moisture absorption and quick-drying, warm and breathable, natural flame retardant, skin-friendly and health-preserving functions. .

Embodiment 1- Embodiment 41

[0098] Embodiment 1-embodiment 41 provides a kind of preparation method of cowhide collagen fiber, and described preparation method comprises the steps:

[0099] Select waste cowhide with basically the same thickness to cut the cowhide according to the process parameters provided in Table 2. The cut cowhide is stirred and softened while soaking in water. The soaking treatment method and process parameters are shown in Table 1. Show, the formula of auxiliary agent is as shown in table 3, and wherein, table 3 represents per 100 parts of water, adds the parts by weight of the component of each auxiliary agent;

[0100] In the preparation method provided in Example 33, the cowhide is stirred by turbine stirring, and in the other examples, it is stirred in a rotating pot equipped with a stirring rod with a spike, and then the softened and expanded cowhide is loosened-opened Steps of loosening-cleaning and separation-finishing-drying-secondary opening;

[0101] First, the softened ...

Abstract

The invention provides a preparation method of cattle-hide collagen fibers as well as prepared cattle-hide collagen fibers and application thereof and relates to the technical field of textiles. According to the preparation method of cattle-hide collagen fibers, with the adoption of a manner of stirring and throw-softening cow leather during soaking, the cow leather can fully absorb treating fluidduring stirring so as to achieve an optimal expanding and softening effect. Moreover, in an opening step of a subsequent process, cattle-hide collagen fiber bundles are beaten by using elastic materials, and physical damage and pressure in the subsequent process can be reduced, so that the cattle-hide collagen fiber prepared by the method have excellent physical and mechanical properties, and quality requirements of prepared textile articles can be met. Moreover, the cattle-hide collagen fibers have the effects of being antibacterial, deodorant, moisture-absorbing, quick-drying, warm and airpermeable, natural flame retardant, skin-friendly, capable of preserving health and the like, and the technical problem in the prior art that a method for producing high-quality cattle-hide collagen fibers does not exist is solved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing bovine hide collagen fibers, the prepared bovine hide collagen fibers and applications thereof. Background technique [0002] Cow leather is mainly a three-dimensional network structure formed by interweaving bundles and microbundles of collagen fibers, interspersed and entangled with each other, and has a dense structure. Cowhide collagen fibers mainly include cowhide collagen fibers, which have excellent physical and mechanical properties, antibacterial and deodorant, moisture absorption and quick drying, breathable and warm, natural flame retardant, skin-friendly and healthy, etc. In recent years, cowhide collagen fibers have been extracted from cowhide scraps Reuse is receiving increasing attention. [0003] Cowhide collagen fibers are mainly used as raw materials for non-woven fabrics, regenerated cowhide leather base fabrics, electrostatic flocking ...
