Problems solved by technology

There are many existing techniques for the fibrous feather down barn to be separated from the feather bar or down core, and the length is generally 15-30mm. The natural fibrous feather down barn has no curl, and the barn is from After the down core or feather shaft is separated, it is in a fluffy state, and the cohesion is very poor. Therefore, it is difficult to directly process nonwovens.
For example, the barn is directly mixed with textile fibers, and the non-woven process is carried out by using the cohesion of textile fibers or by other methods, such as crushing the barn through the wet-laid process for non-woven process, even if it is formed into a product, but the finished product In the product, the barbs cannot be entangled with the textile fibers, but are formed solely by the entanglement of the textile fibers or by bonding, and the barbs mostly exist in a straight state in the material. Therefore, the product Poor tensile strength, poor elasticity, uneven product structure, poor surface smoothness, and easy shedding; products co-processed with textile fabrics are easy to drill during use, and it is difficult to process high-quality products

example 2

[0028] Example 2 as figure 1 .2.4.7 100% of fibrous feathers and feathers

[0029] The non-woven fabric is composed of fibrous feather feather branches that are thicker and harder than down silk, and the feather silk feather branches have the advantages of higher tensile strength and longer down feather branches than the down silk feather branches. The fibrous feather feathers are composed of the curled main stem 1, the feather branch 2 on the main stem 1, the nodules 3 and / or the spines 4 on the feather branch 2. At the same time, it is a composite structure that is intertwined and bonded at the intersection 5 by the adhesive. The feather silk is chemically softened and denatured to make the thicker and harder feather silk soft and slightly curled, and then mechanically rubbed and curled to make the curl meet the required requirements, and then filled into the extrusion hot oven and sealed. The temperature of the box is adjusted to 130°C, and the time is set for 5 minutes, ...

example 3

[0030] Example 3 as figure 1 .2.6.8 80% fibrous feather and feather branches, 20% heat-melt bonded fibers

[0031]The fibrous feather feather branches are formed by the crimped main stem 1, the feather branch 2 on the main feather stem 1, the nodules 3 and / or spines 4 on the feather 2 and the heat-melt-bonded fibers 6. It is a composite structure of intertwining and intertwining and bonding together, and the intersecting points 5 of which are intertwined and cohesive are bonded together. The fibrous feather feather branches are deformed by mechanical rubbing, and then filled into the extrusion hot oven to seal, the temperature of the hot oven is adjusted to 170 ° C, and the setting time is 2 minutes, so that the feather branches form a stereotyped curl shape, and then the 80% of the feather and feather branches are mixed with 20% of the opened hot melt adhesive fibers, and the mixed material is combed, air cluttered into a network, and heated to make the hot melt adhesive fib...

example 4

[0032] Example 4 is shown in the figure: 1.2.5.8 Fibrous feather down branch 50% viscose fiber 50%

[0033] The non-woven fabric is composed of curled fibrous feather feather branches and viscose fibers, and the fibrous feather feather branches are composed of a curled feather branch main rod 1, feather branchlets 2 on the feather branch main rod 1, The nodules 3 and / or spines 4 on the feather twigs 2 and the viscose fibers 6 form a sheet-like composite structure that is evenly intertwined with each other. The fibrous feather and feather branches are softened and curled by chemical softening and denaturation treatment, and mixed with viscose fibers in the stated proportion; The existing process is shaped to form a fibrous feather down branch and viscose fiber blended non-woven fabric. The non-woven fabric has the advantages of compactness, high heat retention rate, good surface flatness, good moisture absorption, good air permeability, etc., and is suitable for making air-con...

Abstract

The present invention discloses a non-woven fabric of down with crimped fiber and its production process. Down is twisted together via its crimped stem, small branches, nodes and stabs on the branches. The non-woven fabric is produced through preparation of fiber down, chemical softening modification and / or mechanical kneading deformation, hot extruding to set, down setting, carding, air flow netting or mechanical netting, and knitting through needling, hydro-entangled, hot bonding, chemical bonding or sewing. The non-woven fabric has high elasticity, high tensile strength, high heat insualting performance, etc.

Description

Technical field: [0001] The invention relates to a curled fibrous feather down non-woven fabric and a processing method thereof. Background technique: [0002] Feather down is a derivative of poultry skin. It is light in weight and has good thermal insulation properties. Down is divided into floret down, down and flake-shaped feathers, all of which are connected by feather branches to the down core or feather trunk. consist of. Unlike the plush of mammals such as cattle and sheep, it grows directly from the skin surface as fibrous monofilaments. Fibrous feather down is composed of a single feather branch. The feather branch separated from the down core and the down feather is called down silk. The feather branch is soft and slender. There are also many soft and slender feather branches. The feather branches are also called down silk after they are separated from the feather trunk. Later known as feather silk, feather silk is straight without bending. Down silk and feathe...
