Description

Technical Field

[0001] The present invention relates to the technical field of down quilts, in particular to a down quilt and a preparation method thereof. Background Art

[0002] A down quilt is a quilt filled with down. Down is the stemless hair that grows between the neck and chest of waterfowl like geese and ducks. Down offers excellent thermal insulation because down fibers are spherical and contain a large amount of air. Air is a poor conductor of heat, effectively preventing heat dissipation and maintaining warmth. Existing down quilts have some shortcomings in terms of thermal insulation and comfort. To address this, a down quilt and its preparation method have been designed. Summary of the Invention

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a down quilt and a preparation method thereof, which has excellent thermal insulation performance, good air permeability, softness, comfort and durability.

[0004] The technical solution adopted by the present invention to solve the problem is:

[0005] A down quilt comprises: a quilt cover fabric, wherein the quilt cover fabric is hollow inside to form a receiving space, and the quilt cover fabric is made of pure cotton satin fabric; a filler, wherein the filler is filled in the receiving space of the quilt cover fabric, the filler wraps the fabric and the inner core, the inner core is located in the wrapping fabric, and the inner core is made of white goose down and microfiber.

[0006] By adopting this solution, pure cotton satin fabric is soft, skin-friendly, and has a high gloss, providing a comfortable user experience. Its excellent breathability helps keep you dry while sleeping. The hollow interior creates a storage space that is convenient for filling with thermal insulation materials such as down, and it also facilitates air circulation, further enhancing the warmth. White goose down has excellent thermal insulation properties, is light and soft, and has a high loft, effectively blocking the ingress of cold air. Microfiber increases the uniformity and stability of the filling, while also improving the durability of the duvet.

[0007] Furthermore, the warp and weft density of the quilt cover fabric is 133×72 threads / inch, and the gram weight of the quilt cover fabric is 120-140g / m 2 The warp shrinkage rate of the quilt cover fabric is ≤3%, and the weft shrinkage rate is ≤3%.

[0008] By adopting the above solution, such warp and weft density makes the fabric texture tight, which not only ensures the strength of the fabric, but also prevents the down from drilling out, and also has a good feel; the moderate weight makes the quilt cover fabric neither too thick to affect the user experience, but also ensures a certain wear resistance and warmth retention; the low shrinkage rate can make the down quilt maintain good dimensional stability after multiple washings, not easy to deform, and extend the service life.

[0009] Furthermore, the white goose down content of the filling is ≥95%, and the fluffiness of the white goose down is ≥800 cubic inches / ounce.

[0010] By adopting the above solution, the high content of white goose down ensures the warmth retention and lightness of the duvet. The high down content can better store air, form an insulating layer, and resist the cold. The high fluffiness of the white goose down can make the duvet softer and lighter, and can provide greater warmth retention in a smaller space, while also increasing the comfort of the duvet.

[0011] Furthermore, the fineness of the ultrafine fiber is 0.5-1 denier, and the length of the ultrafine fiber is 38-51 mm.

[0012] By adopting this solution, fine microfibers are softer and smoother, blending better with the white goose down, making the filling more uniform and avoiding clumping or uneven distribution. The appropriate length allows the microfibers to form a stable structure after mixing with the white goose down, enhancing the overall stability and durability of the filling and preventing it from falling off or shifting.

[0013] A method for preparing a down quilt, comprising the above-mentioned down quilt and the quilt cover fabric, comprises the following steps:

[0014] S1. Blowing: Beater speed 800-900r / min, cotton box pressure 400-500Pa;

[0015] S2, carding: cylinder speed 360-380r / min, licker-in speed 800-900r / min, flat speed 180-200mm / min;

[0016] S3, drawing: adopt three-pass drawing, the total drafting ratio of the first draw is 6-7 times, and the drafting ratio of the back zone is 1.7-1.8 times; the total drafting ratio of the second draw is 6-7 times, and the drafting ratio of the back zone is 1.5-1.6 times; the total drafting ratio of the final draw is 6-7 times, and the drafting ratio of the back zone is 1.1-1.2 times;

[0017] S4, roving: roving weight 4-5g / 10m, spindle speed 600-700r / min, total draft 5-6 times, back zone draft 1.1-1.2 times;

[0018] S5, spun yarn: spindle speed 15000-16000r / min, front roller speed 18-20m / min, suction negative pressure 1800-2000Pa.

[0019] Furthermore, the filler processing steps are as follows:

[0020] S1. Goose down screening: Use wind selection and screening equipment to control the wind speed at 10-15m / s to screen out high-quality goose down with a down diameter of ≥20mm;

[0021] S2. Cleaning and disinfection: the water temperature is 40-50℃, the detergent dosage is 0.5-1%, and the cleaning time is 20-30min; the disinfection adopts high temperature steam disinfection, the temperature is 120-130℃, and the time is 15-20min;

[0022] S3. Fluffing treatment: Fluffing equipment frequency 30-40Hz, time 30-40min.

[0023] Furthermore, it also includes: filling the filling material into the quilt cover fabric, the filling machine pressure is 0.1-0.2MPa, and the filling speed is 5-8g / s.

[0024] By adopting the above solution, it is ensured that the goose down is evenly filled into the quilt cover fabric, avoiding the situation where there is too much or too little down in some parts. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] See Figure 1 The present invention discloses a down quilt: comprising a quilt cover fabric 1 and a filler 2, wherein the quilt cover fabric 1 is hollow inside to form a receiving space, the quilt cover fabric 1 is made of pure cotton satin fabric, the filler 2 is filled in the receiving space of the quilt cover fabric 1, the filler 2 comprises a wrapping fabric 3 and an inner core 4, the inner core 4 is located in the wrapping fabric 3, and the inner core 4 is made of white goose down and microfiber. Pure cotton satin fabric is soft, skin-friendly and has good glossiness, which can provide users with a comfortable use experience. At the same time, it has good air permeability, which helps to keep users dry during sleep. The internal hollow space forms a receiving space, which is convenient for filling thermal insulation materials such as down, and is conducive to air circulation, further enhancing the thermal insulation effect. White goose down has excellent thermal insulation performance, is light and soft, has high fluffiness, and can effectively block the entry of cold air; microfiber can increase the uniformity and stability of the filler 2, while improving the durability of the down quilt.

[0034] Specifically, one side of the quilt cover fabric 1 is open, and a zipper or a snap button is provided at the open portion to seal the open portion, and the filling 2 can be separated from the quilt cover fabric 1, so that the quilt cover fabric can be washed conveniently.

[0035] It should also be noted that upright lining strips are equidistantly spaced along the length of the wrapping fabric 3. These lining strips are made of a rigid fabric. These lining strips divide the wrapping fabric 3 into multiple modules, each of which can be independently configured. Each module is filled with an inner core 4, and each inner core 4 is sewn through using a through-cut process. This process can secure the position of the down, preventing it from shifting or accumulating during use, and ensuring the uniformity of the warmth of the duvet. Furthermore, the through-cut process can make the quilt's surface smoother, with clean lines and a certain decorative effect.

[0036] Specifically, the warp and weft density of the quilt cover fabric 1 is 133×72 threads / inch, and the gram weight of the quilt cover fabric 1 is 120-140g / m 2 The warp shrinkage rate of the quilt cover fabric 1 is ≤3%, and the weft shrinkage rate is ≤3%. Such a warp and weft density makes the fabric texture compact, which not only ensures the strength of the fabric, but also prevents the down from leaking out, and also has a good hand feel. The moderate weight makes the quilt cover fabric 1 neither too heavy to affect the user experience, but also ensures a certain degree of wear resistance and warmth retention. The low shrinkage rate can enable the down quilt to maintain good dimensional stability after multiple washes, not easy to deform, and extend the service life. The white goose down content of the filling 2 is ≥95%, and the fluffiness of the white goose down is ≥800 cubic inches / ounce. The high content of white goose down ensures the warmth retention and lightness of the down quilt. The high down content can better store air, form a heat insulation layer, and resist the cold. The high fluffiness of the white goose down can make the down quilt softer and lighter, and can provide greater warmth retention in a smaller space, while also increasing the comfort of the down quilt. The microfiber has a fineness of 0.5-1 denier and a length of 38-51 mm. Microfibers with a finer texture are softer and smoother, blending better with the white goose down, making the filling 2 more uniform and preventing clumping or uneven distribution. The appropriate length allows the microfiber to form a stable structure after mixing with the white goose down, enhancing the overall stability and durability of the filling 2 and preventing it from falling off or shifting.
