Problems solved by technology

The processing of natural fur has high requirements on the quality of the raw material and the yield is low. Due to the small size of the animal skin, the scope of use is limited, the price is expensive, and the processing and manufacturing process seriously pollutes the environment.

Embodiment 1

[0036] 1. Web forming: Collagen fiber is used as the raw material for the skin board, and cashmere fiber is used as the raw material for the wool quilt layer. Two air-laid machines are selected, the first web-forming machine is used to process and make the cortex layer fiber web (netting the collagen fibers), and the second web-forming machine is used to process and make the wool quilt layer fiber web (netting the cashmere fibers). ), wherein the two web forming machines are arranged longitudinally in front and back, the transmission curtain of the first web forming machine passes through the bottom of the second web forming machine to the conveying curtain of the spunlace machine, and the transmission curtain of the second web forming machine is connected with the The transmission curtain of the first web forming machine is handed over before the transmission curtain of the spunlace machine, and the transmission line speed of the transmission curtain of the two web forming mac...

Embodiment 2

[0042] 1. Web forming: Collagen fiber is used as the raw material of the skin board; a mixture of discarded mink hair and fox fur is used as the raw material of the fur layer, the fiber web of the leather board layer is air-laid, and the fiber web of the wool layer is carded and laid, and air-laid The transmission curtain is connected with the carding and laying transmission curtain to form a double-layer superimposed fiber web with the fleece layer fiber web on the top and the cortex layer fiber web on the bottom.

[0043] 2. Spunlace consolidation: first pre-wet the superimposed fiber web, and then perform three flat punctures on the upper wool layer fiber web, the pressure is 60bar, 100bar, 80bar respectively, and then transfer to the opposite leather board The first layer of fiber web is stabbed three times on the drum of the hydroentanglement machine, with pressures of 150bar, 200bar, and 50bar respectively, so that the entanglement density of the leather board surface exc...

Embodiment 3

[0046] Process description: A small amount of high-shrinkage polyester is mixed into the collagen fiber bundles of the cortex layer to increase more varieties. All the other processes are the same as in Example 1. The artificial fur structure that makes is identical with embodiment 1.

Abstract

The invention discloses artificial fur and a preparation method thereof. The fur comprises a leatherboard layer and a fleece layer, and is characterized in that: the leatherboard layer has a three-dimensional netlike weaving structure with a collagenous fiber bundle as a main body; and one end and / or the middle end of the fiber of the fleece layer is entangled on the collagenous fiber bundle of the leatherboard layer and is firmly locked by the collagenous fiber bundle. The preparation method comprises the following steps of: web formation, fiber web superposition, spunlaced consolidation, texturing and raising, and contraction shaping before and after the texturing and raising as required to prepare the artificial fur. The weaving structure, appearance and sanitation performance of the fur are consistent with those of natural fur leatherboard and the fur has higher stretching amplitude and wider application field than those of natural fur; the fiber of the fleece layer is embedded into the leatherboard layer by physical entanglement, and the fur does not contain any adhesive and has the operational performance far higher than that of artificial fur manufactured by flocking through an adhesive; and the artificial fur can be manufactured from various leather scraps and waste animal fur and is more environmental-friendly.

Description

technical field [0001] The invention relates to the field of leather, in particular to an artificial fur. Background technique [0002] Fur is a precious clothing and decorative material. At present, commercial fur is divided into natural fur and artificial fur. Natural fur comes from the fur of animals. It is processed by artificial tanning to form usable fur. The skin board is composed of epidermis, dermis and subcutaneous tissue layer, wherein the epidermis and subcutaneous tissue layer have been removed during the tanning process of fur, and the leather board of the finished fur is left with tanned dermis. The dermis is mainly composed of collagen fibers, which interweave and interweave each other in bundles to form a tight three-dimensional network weaving structure. The hair indumentum is composed of three body hairs, namely, guard hairs, fine hairs and coarse hairs, which protrude densely from the skin plate. soft. [0003] Due to the different types of animals, th...
