Embodiment 1

[0014] Embodiment one, by weight ratio collagen fiber 100%

[0015] Technological process: raw material screening - impregnation - depilation - liquid defiberization - degreasing - cleaning and dehydration - drying - opening and removing impurities - mixing - carding - drawing into fiber strips.

[0016] Process description

[0017] 1. Raw material screening: select at least one kind of raw hide from cattle, horse, sheep, pig, dog, deer, rabbit, crocodile and snake, or the corners of untanned leather in the tanning process.

[0018] 2. Soaking: Soak in liquid at room temperature for 1-24 hours to restore the skin to the state of fresh skin.

[0019] 3. Hair removal: use the existing alkaline or enzymatic hair removal technology to remove hair, and this process can be omitted for no fur.

[0020] 4. Liquid defibration: Use a special liquid defibrillator to strike and / or comb the skin repeatedly in the liquid. The liquid defibrating machine can be self-made, and at least one ...

Embodiment 2

[0028] Embodiment two, by weight ratio collagen fiber 100%

[0029] Process flow: raw material screening—dipping—liquid defibrillation—cleaning and dehydration—drying—opening and impurity removal—mixing—carding—drawing into fiber strips.

[0030] 1. Raw material screening: use tanned leather and its corner cuttings and waste leather.

[0031] 2. Dipping: Dipping in the liquid for 10-48 hours at a temperature of 15-60°C.

[0032] The rest of the process is the same as Example 1

[0033] Embodiments 1 and 2 The liquid used for impregnation and liquid defibration is water; according to the difference of leather or leather raw materials, add 0.2-2% detergent, 1-10% grease, 0.2-1.5% penetration and 0.03-0.5% alkali at least one of the substances.

Embodiment 3

[0034] Embodiment 3, the collagen fiber is 5-99.9% and the textile fiber is 0.1-95% by weight.

[0035] Process flow: mixing - carding - drafting into fiber strips.

[0036] Process description:

[0037] 1. Mixing: the collagen fibers processed in Embodiment 1 or 2 are mixed with at least one spinnable fiber in all chemical fibers of cotton, wool, hemp, silk and polyester, acrylic fibers, nylon fibers and viscose, according to the above ratio. match.

[0038] All the other procedures are the same as example one.

Abstract

The invnetion relates to a spinning fiber rod comprised of 5-100% collagen fiber and residual textile fiber. Wherein, the process method comprises: screening material, dipping, defibering, degreasing, cleaning, dewatering, drying, opening to remove impurity, mixing, carding, and drafting. This invention can obtain material from wide source, has well applicability, high tensile strength, well moisture / oil absorption properties, and fit to spread in textile industry.

Description

technical field [0001] The invention relates to a fiber strip for spinning and a processing method thereof, which is a fiber strip for spinning made of animal skin or leather collagen fiber and a processing method thereof. Background technique [0002] At present, fiber slivers for spinning are all made of spinnable natural or chemical fibers, which are processed through opening, carding, and drafting processes to form fiber aggregates with a certain linear density and arranged longitudinally in sequence—fiber slivers. The fiber sliver can be spun and weaved, but the natural fiber resources are limited by nature, the cost is high, and the wear resistance and tensile strength are low; while the chemical fiber has poor water absorption, comfort and flame retardancy, and the textile The industry is in urgent need of a more ideal natural fiber. [0003] There are many kinds of animal skin, which is a very complex biological tissue, but its structure is similar, all of which are...
