Problems solved by technology

From the analysis of length and strength elongation, feather silk and down silk have certain spinnability, but feather fiber has a surface morphology completely different from that of mammalian hair fiber. There is no obvious scale layer, only a vertically arranged texture with ups and downs Therefore, there is no shrinkage phenomenon in feather fibers, it is in a fluffy state, less curling, and high static electricity, which is not conducive to the cohesion of fibers, and it is difficult to spin and weave.
If only feathers are used to form a web through a non-woven process, the strength is low, the hair loss is serious, and the feasibility is very small.

Embodiment 1

[0035] The feather nonwoven fabric is composed of feather fibers (1) and low melting point PET bicomponent fibers (2). Feather fiber (1) and low-melting point PET bi-component fiber (2) are preliminarily mixed in a mass ratio of 70:30, adjusted to humidity and added oil to remove static electricity, then opened, impurity removed, mixed, and then fed into Rando airlaid Form the fiber web, adjust the speed of the web feeding roller (6) and the web forming curtain (10) to change the fiber web density at 150-200g / m 2 between, such as image 3 . The fiber web is fed into the acupuncture machine, and the number of acupuncture passes is set to 2, such as image 3 . Then fill in the hot air oven such as Figure 4 , the hot melt temperature is 120 degrees, and the bonding time is 5 minutes. compound device such as Figure 5 , the direction of the spunbond nonwovens is the same as that of the feather nonwovens, both of which are in the same direction as the output of the machine.

Embodiment 2

[0037] The feather nonwoven fabric is composed of feather fibers (1) and low melting point PET bicomponent fibers (2). Feather (1) and low-melting-point PET bicomponent fiber (2) are preliminarily mixed in a mass ratio of 60:40, adjusted to humidity and added to remove static electricity, then opened, removed, mixed, and then fed into the Rando air-laid machine Form fiber web, adjust the speed of web feeding roller (6) and outlet web forming curtain (10) to change the fiber web density at 150-220g / m 2 between, such as image 3 . The fiber web is fed into the acupuncture machine, and the number of acupuncture passes is set to 3, such as image 3 . Then fill in the hot air oven such as Figure 4 , the hot melt temperature is 130 degrees, and the bonding time is 5 minutes. compound device such as Figure 5 , the direction of the spunbond nonwovens is the same as that of the feather nonwovens, both of which are in the same direction as the output of the machine.

Embodiment 3

[0039] The feather nonwoven fabric is composed of feather fibers (1) and low melting point PET bicomponent fibers (2). Feather (1) and low-melting-point PET bicomponent fiber (2) are preliminarily mixed in a mass ratio of 50:50, adjusted to humidity and added oil to remove static electricity, then opened, impurity removed, mixed, and then fed into the Rando air-laid machine Form the fiber web, adjust the speed of the web feeding roller (6) and the outlet web forming curtain (10) to change the fiber web density at 180-250g / m 2 between, such as image 3 . The fiber web is fed into the acupuncture machine, and the number of acupuncture passes is set to 4, such as image 3 . Then fill in the hot air oven such as Figure 4 , the hot melt temperature is 130 degrees, and the bonding time is 10 minutes. compound device such as Figure 5 , the direction of the spunbond nonwovens is the same as that of the feather nonwovens, both of which are in the same direction as the output of t...

Abstract

The invention relates to a non-woven feather fiber filtering composite material and a preparation method thereof, comprising: a layer of non-woven feather fabric (3) and two layers of non-woven unbound fabric (4), which are all compounded by machine; and the preparation method comprises steps as follows: (1) feather fiber (1) and bi-component fiber (2) are mixed evenly according to a mass proportion of 1-2.5:1 and fed into a air-laid web-forming machine to obtain a non-woven feather fiber web (9) which is then directly fed into a needle machine to be reinforced by needling and a fiber web (21) is obtained; and (2) the fiber web (21) directly enters a hot-air oven to be reinforced by hot melting and a non-woven feather fabric (3) is obtained, and the non-woven feather fabric (3) is compounded up and down with a layer of non-woven unbound fabric (4) and then wound into shape by a winding device to obtain the non-woven filtering composite material (5). The non-woven filtering material has good uniformity, no fiber loosing, certain degree of tensile strength and tearing strength and good filtering performance, can adsorb heavy metals, dyes, oil stains, organic solvents and other harmful substances, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the field of nonwoven composite material and its preparation, in particular to a nonwoven filter composite material of feather fiber and its preparation method. Background technique [0002] my country is a big country in the production and trade of down, feathers and their products. Down and feather resources are very rich, with an annual output of more than 600,000 tons. The domestic market has formed a market size of 30 billion yuan, accounting for 60% of the world's total output. At present, although the down which accounts for about 20% of the total feather weight has been widely used as a thermal insulation filling material, a large amount of remaining feather fibers are treated as waste, and only 3-5% of them are used at present. Filling materials, badminton and handicrafts, a small amount of protein is extracted as fertilizer. The research and development of feathers and their products at home and abroad still remain a...
