Description

Technical Field

[0001] The invention relates to the field of down processing, and in particular to a mixed down of chemical fiber pearl cotton particles and duck silk and a preparation method thereof. Background Art

[0002] In the textile industry, duck silk refers to a filling made of a mixture of duck feathers and duck down. This filling is soft, comfortable, and warm, so it is widely used in the manufacture of home textiles, such as cushions, floor mats, pillows and other household items. Duck silk filling is usually white or off-white in color, and its shape is somewhat similar to cotton, but it is more delicate than cotton. When making household items, duck silk filling needs to be compressed to ensure the density and comfort of the filling. In addition, duck silk filling has good durability and will not deform or compress due to long-term use, and will not produce odor.

[0003] Chemical fiber pearl cotton is a kind of chemical fiber, which can be divided into regenerated fiber and synthetic fiber according to the raw materials. Regenerated fiber is made of natural polymer compounds (such as wood, bagasse, reed, etc.) as raw materials and is made through chemical processing. Common regenerated fibers include viscose fiber, strong fiber, cuprammonium fiber, etc. Among them, viscose fiber has excellent hygroscopicity, air permeability and dyeability, but poor wear resistance; strong fiber has higher strength and wear resistance, but its hygroscopicity is slightly inferior to viscose fiber. Synthetic fiber is made of low molecular organic compounds as raw materials through polymerization and spinning process. Common synthetic fibers include polyester, nylon, acrylic, polypropylene, spandex, etc. Chemical fiber pearl cotton is used as filler, filled in dolls, sofas, cushions, etc., and can also be used as clothing filler, but due to the poor warmth retention of chemical fiber pearl cotton, its application in clothing is limited.

[0004] Mixed down is a mixture of two or more different filling materials, and can be used as filling for clothing or quilts. For example, mixed down made of animal down and chemical fiber down has both the warmth retention of animal down and the durability and maintenance convenience of chemical fiber down, and can also reduce production costs. However, compared with pure down filling, the chemical fiber down in the mixed down will still reduce the overall warmth retention performance. Secondly, the existing mixed down filling also has problems such as low fluffiness and poor resilience. Summary of the invention

[0005] The invention aims to provide a mixed down of chemical fiber pearl cotton particles and duck silk, wherein the mixed down filling material is made of duck silk and chemical fiber pearl cotton as main raw materials, and has excellent warmth retention, air permeability, high resilience and high fluffiness.

[0006] Another object of the present invention is to provide a method for preparing a mixed velvet of chemical fiber pearl cotton particles and duck silk. The method has a simple process and the prepared mixed velvet has excellent warmth retention, air permeability, high resilience and high fluffiness.

[0007] The present invention solves the technical problem by adopting the following technical solutions.

[0008] On the one hand, an embodiment of the present invention provides a mixed velvet of chemical fiber pearl cotton particles and duck silk, which includes the following raw materials by mass percentage:

[0009] Duck silk 60-70%, chemical fiber pearl cotton 30-40%.

[0010] In some embodiments of the present invention, the following raw materials are included: 70% duck silk and 30% chemical fiber pearl cotton.

[0011] On the other hand, an embodiment of the present invention provides a method for preparing a mixed velvet of chemical fiber pearl cotton particles and duck silk, comprising the following steps:

[0012] S1, feeding the chemical fiber pearl cotton into the nail curtain stirring machine to evenly break up the chemical fiber pearl cotton; after breaking up, the chemical fiber pearl cotton enters the cotton stripping machine, the chemical fiber pearl cotton is combed and controlled by the cotton stripping machine and transferred to the cotton opener, and after the cotton opening process, it enters the ball cotton machine to obtain chemical fiber pearl cotton particles;

[0013] S2, adding the chemical fiber pearl cotton particles and duck silk prepared in step S1 into a down stacking machine, mixing them at room temperature, to obtain the mixed down.

[0014] In some embodiments of the present invention, in the step S1, the processing temperature of the chemical fiber pearl cotton in the ball cotton machine is 45-50°C, and the processing time is 50-60s.

[0015] In some embodiments of the present invention, in step S1, the processing temperature is 50° C. and the processing time is 60 s.

[0016] In some embodiments of the present invention, in step S2, the chemical fiber pearl cotton particles and the duck silk are mixed in the down stacking machine for 25-30 minutes.

[0017] In some embodiments of the present invention, in step S2, the mixing time is 30 minutes.

[0018] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0019] The chemical fiber pearl cotton particles and duck silk mixed down provided by the present invention use duck silk and chemical fiber pearl cotton as raw materials, the raw materials have low density and good lightness, and the mixed filling can maintain the lightness of the down jacket, which is convenient to carry and wear. Secondly, duck silk has warmth retention, and because it contains more air, it can effectively isolate the cold. When duck silk and chemical fiber pearl cotton are used together, the duck silk can improve the warmth retention of the mixed down, and the polyester fiber can improve the fluffiness of the mixed down. The combination of the two can reduce the production cost of the mixed down while ensuring the warmth retention of the mixed down.

[0020] The mixed down preparation method provided by the present invention comprises the following steps: firstly subjecting chemical fiber pearl cotton to a cotton stripping machine and a cotton opener to process the chemical fiber pearl cotton, and then subjecting the chemical fiber pearl cotton to a cotton ball machine to prepare fluffy chemical fiber pearl cotton particles, and then uniformly mixing the chemical fiber pearl cotton particles with duck silk in a down stacking machine to prepare mixed down. The mixed down prepared by the method has high fluffiness, resilience, and good warmth retention, and can achieve high warmth retention with a small filling amount, and has good air permeability.
