Description

Technical Field

[0001] This invention relates to the field of silk product technology, specifically to a high-quality mulberry silk quilt based on ecological silkworm farming and its preparation method. Background Technology

[0002] Silk quilts are highly favored by consumers in the home textile industry due to their lightweight, breathable, comfortable, and warm properties. Currently, the filling materials for silk quilts on the market mainly rely on double cocoon silk, pupa lining cotton, and tussah silk. However, the above-mentioned raw materials and corresponding preparation processes have the following defects:

[0003] 1. Feed substitution in the industry: Due to farmers losing land in recent years and pursuing convenient feeding and reduced labor costs, some silkworm farming has long adopted the method of abandoning mulberry trees and feeding artificial feed, resulting in a year-by-year decline in the quality of cocoons and silk.

[0004] 2. Raw material defects: Double-cocoon silk is made from multiple silkworms spinning cocoons together. The interlacing of the silk threads results in uneven fiber thickness, natural bumps on the surface, a rough feel, poor luster, and weakens the close fit of the silk quilt. At the same time, its natural formation rate is low, and the output is difficult to meet the needs of large-scale production. Tussah silk fibers are coarse and hard, and are prone to static electricity. They require chemical bleaching with fluorescent whitening agents, which poses health risks. The fibers are short and have poor toughness. They are prone to clumping and hardening during use, reducing warmth and requiring frequent maintenance. In addition, tussah silkworms are raised in the wild, and the cocoons are prone to accumulating impurities, making it difficult to guarantee cleanliness.

[0005] 3. Insufficient silkworm breeding and cocoon processing: There is no meticulous and strict control over the silkworm's growth environment, and there is a lack of breeding of silkworms, resulting in poor cocoon quality. Moreover, directly processing cocoons containing live silkworm pupae violates ecological principles. Summary of the Invention

[0006] The purpose of this invention is to provide a high-quality mulberry silk quilt based on ecological silkworm breeding and its preparation method, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a method for preparing a high-quality mulberry silk quilt based on ecological silkworm breeding, comprising the following steps: Step 1, ecological breeding of silkworms; Step 2, ecological pretreatment of silkworm cocoons; Step 3, cocoon shell treatment; Step 4, preparation of silk floss; Step 5, drying of silk floss; Step 6, preparation of the mulberry silk quilt.

[0008] In step one above, high-quality silkworm cocoons are obtained by controlling the environmental parameters for the growth of silkworms, providing high-quality mulberry leaf feed, implementing refined breeding, and strictly controlling hygiene during the breeding process.

[0009] In step two above, after the silkworm pupae inside the cocoon emerge, mate, and lay eggs, the intact cocoon shells are collected.

[0010] In step three above, intact cocoons are boiled and washed and dehydrated to remove impurities and residual sericin.

[0011] In step four above, the dehydrated cocoon shells are processed into sheet-like silk floss through a cotton-opening process.

[0012] In step five above, the sheet-like silk floss is placed in a cool and ventilated place to air dry naturally, and the moisture content of the sheet-like silk floss after drying is controlled to be ≤12%, thus obtaining dried silk floss.

[0013] In step six above, the dried silk floss is fluffed up and then laid on the quilt bed, and then hand-quilted to make a mulberry silk quilt.

[0014] Preferably, in step one, the specific environmental parameters for the growth of silkworms are as follows: the temperature is maintained at a constant temperature of 25℃±0.5℃, the humidity is adjusted according to the instar gradient, the humidity of the growth environment for 1st-2nd instar silkworms is 85%-90%, the humidity of the growth environment for 3rd-4th instar silkworms is 75%, the humidity of the growth environment for 5th instar silkworms is 65%, the lighting adopts a regular light-dark cycle of 16 hours of light and 8 hours of darkness, and the type of lighting is soft diffused light. At the same time, the air in the silkworm room is kept in circulation, maintaining micro-airflow circulation, and strong winds are strictly prohibited from blowing directly on the silkworms.

[0015] Preferably, in step one, the feeding of high-quality mulberry leaves must meet the following requirements: the source of mulberry leaves must be free of pesticide residues and pollution; the mulberry leaves must be stored in a cool environment at 15-20℃ and relative humidity of 70%-80% for no more than 3 hours; 1-2 instar silkworms should be fed tender and mature leaves, and 3-5 instar silkworms should be fed mature leaves; they should be fed 6 times a day, with the time interval between two consecutive feedings controlled at 4-5 hours.

[0016] Preferably, in step one, the refined selection and breeding specifically involves: throughout the entire breeding cycle of the silkworms, continuously screening and eliminating diseased silkworms, weak silkworms, small silkworms, and silkworms with slow development, retaining only those silkworms that are physically strong, have a symmetrical body shape, are active, and eat mulberry leaves vigorously.

[0017] Preferably, in step one, the strict hygiene control during the breeding process specifically includes: pre-breeding disinfection, in-breeding disinfection, and personnel management. Pre-breeding disinfection specifically involves cleaning the silkworm room, silkworm rearing equipment, and the environment within a 10-meter radius of the breeding area, followed by sequential disinfection using 1%-2% formaldehyde spray, 10%-15% lime water soaking for 30-60 minutes, and 10%-15% bleaching powder fumigation for 2-4 hours. In-breeding disinfection specifically involves removing silkworm excrement daily and sprinkling fresh lime powder on the silkworm rearing bed every 1-3 days, at a rate of 5-10 g / m². 2 Personnel management is as follows: operators must change into special shoes and clothing, and their hands must be wiped and disinfected with 75% alcohol before entering the silkworm room.

[0018] Preferably, in step two, the environmental conditions for silkworm pupae to emerge, mate, and lay eggs are: temperature controlled at 24-28℃, humidity controlled at 70%-80%, and the environment is well-ventilated and free from direct sunlight.

[0019] Preferably, in step three, the cocoon boiling process specifically involves: placing the collected naturally exiled cocoon shells into a container and boiling them in water at a temperature of 90-98℃ containing 0.5-1% edible alkali for 20-30 minutes. The edible alkali includes food-grade sodium carbonate and food-grade sodium bicarbonate. The washing and dehydration process specifically involves: rinsing the boiled cocoon shells repeatedly with clean water 3-4 times to remove residual sericin and edible alkali. After rinsing, the cocoon shells are dehydrated using a dehydrator at a speed of 1000-1500 r / min for 5-8 minutes, controlling the moisture content of the dehydrated cocoon shells to be ≤20%.

[0020] Preferably, in step four, the opening process specifically involves: pouring the dehydrated cocoon shells into an opening machine, where a robotic arm combs the silk threads at a frequency of 30-40 times per minute to produce uniform sheet-like silk floss with a thickness of 2.5-3.5 mm.

[0021] Preferably, in step six, the layering specifically involves: layering the dried silk floss evenly on the quilt bed after fluffing it up, using a crisscross pattern, with the edges of each layer aligned with the quilt bed markings; the hand quilting specifically includes the following steps:

[0022] a) Cutting the silk floss to the correct length: Cut the silk floss according to the length and width ratio of the tire cover, with the cutting size being 115% of the length and width of the tire cover.

[0023] b) Making the quilt filling: Lay the silk floss in a crisscross pattern along the edge of a pure cotton mesh with a mesh size of 1-2mm. Sew the edges of the mesh 5cm from the edge with a stitch spacing of 3-5cm and a continuous straight line. Make 3-4 fixed-point quiltings along the diagonal in the middle of the quilt filling to make the quilt filling.

[0024] c) Fitting the quilt cover: Insert the inner quilt core into the pure cotton quilt cover, quilt at fixed points, and fix the four corners, center and midpoints of the four sides to obtain a silk quilt.

[0025] A high-quality mulberry silk quilt based on ecological silkworm breeding, wherein the mulberry silk quilt is prepared by the above-mentioned method.

[0026] Compared with existing technologies, the beneficial effects of this invention are as follows: By controlling the environmental parameters for silkworm growth, providing high-quality mulberry leaf feed, implementing refined breeding, and strictly controlling hygiene during the breeding process, this invention produces high-quality mulberry silk with fine and uniform fibers. This solves the problems of rough and lumpy lining of pupa silk, poor conformability of double silk, and coarse, stiff, static-prone tussah silk and chemical bleaching residue. By processing the naturally molted cocoons after the silkworm pupae have emerged and laid eggs, the invention balances the continuation of the silkworm pupae's life and the quality of the cocoon silk. The resulting silk quilt possesses excellent conformability, warmth, breathability, antistatic properties, durability, and fiber quality, while also meeting consumers' demand for high-quality, healthy, and eco-friendly home textile products.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see the appendix Figure 1 The present invention provides an embodiment of a method for preparing a high-quality mulberry silk quilt based on ecological silkworm breeding, comprising the following steps: Step 1, ecological breeding of silkworms; Step 2, ecological pretreatment of silkworm cocoons; Step 3, cocoon shell treatment; Step 4, preparation of silk floss; Step 5, drying of silk floss; Step 6, preparation of the mulberry silk quilt.

[0030] In step one above, high-quality silkworm cocoons are obtained by controlling the environmental parameters for silkworm growth, providing high-quality mulberry leaf feed, implementing meticulous breeding, and strictly controlling hygiene during the rearing process. Specifically, the environmental parameters for silkworm growth are: maintaining a constant temperature of 25℃±0.5℃; adjusting humidity according to instar progression: 85%-90% humidity for 1st-2nd instar silkworms, 75% for 3rd-4th instar silkworms, and 65% humidity for 5th instar silkworms; using a regular light-dark cycle of 16 hours of light and 8 hours of darkness, with soft, diffused light; maintaining good air circulation in the silkworm rearing room, ensuring micro-airflow, and strictly prohibiting strong winds from blowing directly on the silkworms; and ensuring that the mulberry leaf feed meets the following requirements: the mulberry leaves must be free of pesticide residues and pollution; the mulberry leaves must be stored in a cool environment at 15-20℃ and 70%-80% relative humidity for no more than [a certain period of time is missing in the original text]. After 3 hours, 1st and 2nd instar silkworms are fed tender, moderately ripe leaves, while 3rd to 5th instar silkworms are fed mature leaves. They are fed 6 times a day, with an interval of 4-5 hours between feedings. Refined breeding involves continuously screening and eliminating diseased, weak, small, and slow-developing silkworms throughout the entire rearing cycle, retaining only those that are robust, well-proportioned, active, and actively consuming mulberry leaves. Strict hygiene control during the rearing process includes pre-rearing disinfection, in-rearing disinfection, and personnel management. Pre-rearing disinfection involves cleaning the silkworm rearing room, equipment, and the environment within a 10-meter radius of the rearing area, followed by spraying with 1%-2% formaldehyde, soaking in 10%-15% lime water for 30-60 minutes, and fumigating with 10%-15% bleaching powder for 2-4 hours. In-rearing disinfection involves removing silkworm excrement daily and sprinkling fresh lime powder on the silkworm rearing bed every 1-3 days, at a rate of 5-10 g / m². 2 Personnel control measures include: operators must change into special shoes and clothing, and their hands must be disinfected with 75% alcohol before entering the silkworm rearing room;

[0031] In step two above, after the silkworm pupae inside the cocoon emerge, mate, and lay eggs, the intact cocoon shells are collected. The environmental conditions for the silkworm pupae to emerge, mate, and lay eggs are: temperature controlled at 24-28℃, humidity controlled at 70%-80%, and the environment is well-ventilated and free from direct sunlight.

[0032] In step three above, the collected naturally exiled cocoon shells are placed in a container and steamed in water at 90-98℃ containing 0.5-1% edible alkali for 20-30 minutes. The edible alkali includes food-grade sodium carbonate and food-grade sodium bicarbonate. After steaming, the cocoon shells are rinsed repeatedly with clean water 3-4 times to remove residual sericin and edible alkali. After rinsing, the cocoon shells are dehydrated using a dehydrator at 1000-1500 r / min for 5-8 minutes, and the moisture content of the dehydrated cocoon shells is controlled to be ≤20%.

[0033] In step four above, the dehydrated cocoon shells are poured into a cotton-opening machine, where a robotic arm combs the silk threads at a frequency of 30-40 times per minute to produce uniform sheet-like silk floss with a thickness of 2.5-3.5 mm.

[0034] In step five above, the sheet-like silk floss is placed in a cool and ventilated place to air dry naturally, and the moisture content of the sheet-like silk floss after drying is controlled to be ≤12%, thus obtaining dried silk floss.

[0035] In step six above, the dried silk floss is fluffed up at a weight of 285-835g per square meter, then evenly layered on the quilt bed in a crisscross pattern, with the edges of each layer aligned with the markings on the quilt bed. The quilt is then hand-quilted to create a silk quilt, specifically including the following steps:

[0036] a) Cutting the silk floss to the correct length: Cut the silk floss according to the length and width ratio of the tire cover, with the cutting size being 115% of the length and width of the tire cover.

[0037] b) Making the quilt filling: Lay the silk floss in a crisscross pattern along the edge of a pure cotton mesh with a mesh size of 1-2mm. Sew the edges of the mesh 5cm from the edge with a stitch spacing of 3-5cm and a continuous straight line. Make 3-4 fixed-point quiltings along the diagonal in the middle of the quilt filling to make the quilt filling.

[0038] c) Fitting the quilt cover: Insert the inner quilt core into the pure cotton quilt cover, quilt at fixed points, and fix the four corners, center and midpoints of the four sides to obtain a silk quilt.

[0039] Experimental example:

[0040] The mulberry silk quilt prepared according to the above embodiments was used as the experimental group, the commercially available double-silk quilt was used as control group 1, and the commercially available tussah silk quilt was used as control group 2. Tests were conducted on warmth retention (according to GB / T35762-2017 Test Method for Heat Transfer Properties of Textiles - Plate Method), breathability (according to GB / T5453-2025 Determination of Air Permeability of Textile Fabrics), antistatic properties (according to GB / T12703.1-2021 Evaluation of Static Electricity Properties of Textiles), durability (according to GB / T8629-2017 Test Procedures for Household Washing and Drying of Textiles), and fiber quality. The test results are shown in the table below. The table shows that the mulberry silk quilt prepared by this method is significantly superior to existing double-silk and tussah silk quilts in terms of warmth retention, breathability, antistatic properties, durability, and fiber quality.

[0041]

[0042]

[0043] Based on the above, the advantages of this invention are as follows: when used, by controlling the environmental parameters for the growth of silkworms, providing high-quality mulberry leaf feed, implementing refined breeding, and strictly controlling hygiene in the breeding process, high-quality mulberry silk with fine and uniform fibers is produced. This solves the problems of roughness and poor conformability of double silk, as well as the problems of coarseness, static electricity, and chemical bleaching residue in tussah silk. In the processing stage, intact cocoon shells after the silkworm pupae have emerged and laid eggs are used to ensure the continuation of the silkworm pupae's life and avoid the ecological defects of processing live pupae. The resulting silk quilt has better warmth retention, breathability, antistatic properties, durability, and fiber quality than existing double silk and tussah silk quilts.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
