Example Embodiment

[0022] Example 1

[0023] The fabric of the baby quilt is made by blending 70wt% polylactic acid fiber (fineness 0.1D, D-lactic acid content 0.1wt%, molecular weight 150,000, molecular weight distribution 1.0) and 30wt% seaweed fiber (fineness 1.5D); The filling of the quilt is polylactic acid short fiber (fineness 4D, length 30mm) containing 5wt% seaweed charcoal (5000 mesh).

[0024] The warmth retention result of the baby quilt is: 35.3℃.

[0025] The moisture affinity of the baby quilt is: 238ml.

Example Embodiment

[0026] Example 2

[0027] The fabric of the baby quilt is made by blending 90wt% polylactic acid fiber (fineness 0.5D, D-lactic acid content 0.08wt%, molecular weight 180,000, molecular weight distribution 1.1) and 10wt% seaweed fiber (fineness 5D); The filler is polylactic acid short fiber (fineness 10D, length 50mm) containing 15wt% modified seaweed charcoal (10000 mesh).

[0028] The warmth retention result of the baby quilt is: 36.5℃.

[0029] The moisture affinity of the baby quilt is 240ml.

[0030] The modified seaweed charcoal in the examples is prepared by mixing seaweed charcoal with L-lactide and 1,2-cyclohexanediol diglycidyl ether, and then stirring at 60°C for 5 minutes. Based on 100% of the mass of seaweed charcoal before activation and modification, the mass of L-lactide is 2%, and the mass of 1,2-cyclohexanediol diglycidyl ether is 4%.

Example Embodiment

[0031] Example 3

[0032] The fabric of the baby quilt is made of 80wt% polylactic acid fiber (fineness 0.3D, D-lactic acid content 0.09wt%, molecular weight 200,000, molecular weight distribution 1.2) and 20wt% seaweed fiber (fineness 4D) blended; The filler is polylactic acid short fiber (fineness 6D, length 40mm) containing 10wt% seaweed charcoal (8000 mesh).

[0033] The warmth retention result of baby quilt is: 35.8℃.

[0034] The moisture affinity of the baby quilt is: 235ml.

Abstract

The invention relates to a biodegradable baby quilt with a high warmth keeping property and belongs to the technical field of high molecular materials. The biodegradable baby quilt with the high warmth keeping property comprises shell fabric and filler. The shell fabric is formed by blending 70-90wt% of polylactic acid fibers and 10-30wt% of alginate fibers. The filler is made of polylactic acid short fibers containing 5-15wt% of alginate carbon. The polylactic acid fibers and the alginate fibers are combined ingeniously, and therefore the biodegradable baby quilt is good in hydrophily, biocompatibility, antibacterial activity and comfort level. The quilt is suitable for a baby, the shell fabric and the filler are adjusted and designed, the 10-30wt% of alginate fibers are introduced into the shell fabric, and therefore a hydrophilic property of the shell fabric is improved; alginate carbon ingredients are introduced into the polylactic acid short fiber filler, the short fibers have a far infrared ray release function, and therefore the warmth keeping property of the baby quilt is greatly improved.

Description

technical field [0001] The invention relates to a high warmth-retaining biodegradable baby quilt, which belongs to the technical field of polymer materials. Background technique [0002] In recent years, the increasingly serious white pollution problem caused by plastics has attracted more and more attention. Aliphatic polyester / copolyester and aliphatic-aromatic copolyester materials have good biodegradability, help to solve the problem of "white pollution" caused by traditional plastics, and are gradually favored by people. Currently commercialized biodegradable plastics include polylactic acid PLA, polybutylene succinate PBS, polyhydroxyalkanoate PHAs, etc. Among them, polylactic acid was developed the earliest, has the largest production capacity, and is the most widely used. It is used in injection molding, blister, blown film, bottle blowing, spinning fiber and other fields. Polylactic acid can be made into long fibers and short fibers of various specifications by me...
