Problems solved by technology

Although this kind of silk non-woven fabric has good performance in terms of warmth retention, air permeability, moisture absorption, and moisture release compared with other non-woven fabrics made of other natural fibers or chemical fibers, it is added in the production process. Chemicals cannot meet people's environmental protection requirements for daily necessities; at the same time, this non-woven fabric is made of short fibers superimposed and laid, and the sericin on the surface of the silk is removed during processing, the sericin protein is reduced, and the quality of the silk is greatly affected. Large, silk and silk are bonded by chemicals, and the fastness is poor

Embodiment 1

[0025] Embodiment 1. Natural colored cocoon shell cloth lampshade

[0026] 1) Splitting the cocoon: For the elliptical cocoon, cut it in the direction of the long axis, and peel off the silkworm chrysalis;

[0027] 2) Cocoon peeling: the cocoon shell after cutting the cocoon is peeled off to 3-10 layers to form cocoon shell flakes;

[0028] 3) Laying: the lampshade is fixed, and the cocoon shell sheets are superimposed and laid according to the lampshade;

[0029] 4) Humidification: evenly spray water mist on the superimposed cocoon shell sheets, so that the cocoon shell sheets contain 5-50% moisture;

[0030] 5) Hot pressing: Use a hot pressing plate to carry out vertical hot pressing on the cocoon shell sheet at 70-100°C, and the hot pressing time is until the cocoon shell sheet is dry;

[0031] 6) Repair: Repair the insufficient part of the formed cocoon shell restructured non-woven fabric, humidify, heat, and pressurize again, and finally form the style of the lampshade....

Embodiment 2

[0032] Embodiment two, food packaging

[0033] 1) Splitting the cocoon: For the elliptical cocoon, cut it in the direction of the long axis, and peel off the silkworm chrysalis;

[0034] 2) Cocoon peeling: the cocoon shell after cutting the cocoon is peeled off to 3-10 layers to form cocoon shell flakes;

[0035] 3) Laying: superimposing and laying the cocoon shell sheets;

[0036] 4) Humidification: evenly spray water mist on the superimposed cocoon shell sheets, so that the cocoon shell sheets contain 5-50% moisture;

[0037] 5) Hot pressing: Use a hot pressing plate to carry out vertical hot pressing on the cocoon shell sheet at 70-100°C, and the hot pressing time is until the cocoon shell sheet is dry;

[0038] 6) Repair: Repair the insufficient part of the formed cocoon shell non-woven fabric, humidify, heat, heat press again, and finally form;

[0039] 7) Sterilize the formed cocoon shell restructured non-woven fabric with ultraviolet light or the like.

Embodiment 3

[0040] Embodiment three, cosmetic dressing

[0041] 1) Splitting the cocoon: For the elliptical cocoon, cut it in the direction of the long axis, and peel off the silkworm chrysalis;

[0042] 2) Cocoon peeling: the cocoon shell after cutting the cocoon is peeled off to 3-10 layers to form cocoon shell flakes;

[0043] 3) Laying: Make a fixed sample of the cosmetic surface, and lay the cocoon shell sheets according to the fixed sample;

[0044] 4) Humidification: evenly spray water mist on the superimposed cocoon shell sheets, so that the cocoon shell sheets contain 5-60% moisture;

[0045] 5) Hot pressing: Use a hot pressing plate to carry out vertical hot pressing on the cocoon shell sheet at 70-100°C, and the hot pressing time is until the cocoon shell sheet is dry;

[0046] 6) Repair: Repair the insufficient part of the formed cocoon shell non-woven fabric, humidify, heat and pressurize again, and finally form a cocoon shell non-woven fabric;

Abstract

The invention discloses a cocoon recombination non-woven fabric and a manufacturing method thereof, and belongs to the daily necessity field. The materials of the prior art are thicker and have narrow breadth and limited application range, or are adhered by adding chemicals to short silk fiber. The manufacturing method comprises the following steps: oval cocoons are taken as a raw material; and the cocoon recombination non-woven fabric is formed by the steps of cocoon cutting, cocoon stripping, laying, humidifying, hot pressing, patching and the like. The manufacturing method has the advantages that a layered cocoon shell flake is superposed with high temperature for hot pressing and cocoon silk gum hot melt adheres adjacent cocoon shell flakes to form the non-woven fabric, and the non-woven fabric is characterized by wide breadth, no chemical additive, natural and environmental protection, low manufacturing cost, recyclable and degradable product and wide use.

Description

【Technical field】 [0001] The invention relates to a cocoon shell recombined non-woven fabric manufactured by using silkworm cocoon shells and a manufacturing method thereof, belonging to the field of daily necessities. 【Background technique】 [0002] Silkworm cocoons are formed by spinning silkworms and are a natural fiber material. For thousands of years, cocoon shells have been spun mainly through silk reeling, and woven into fabrics to make clothes and bedding. With the increasing development and utilization of silkworm cocoons, the environmental protection requirements for using silkworm cocoons to manufacture daily necessities are also getting higher and higher. In the prior art, the technical scheme disclosed in the invention patent application No. 200510050639.1 "Silkworm Cocoon Protective Clothing and Its Manufacturing Method" is: use ordinary silkworm cocoons to cut them open, compress them with high-temperature steam to shape them into rectangular small cocoons, a...
