It has certain flame retardant performance and similar performance to polyester fiber, and can replace polyester fiber for industrial production. Lactic acid down can be used to make quilts, clothes and other products for warmth.

[0003] To this end, Chinese patent application No. CN114808201A discloses a degradable skin-friendly antibacterial lactic acid down manufacturing method and processing equipment, comprising the following manufacturing steps: S1, using poly-lactic acid chips to manufacture poly-lactic acid fiber; S2, soaking and lubricating the poly-lactic acid fiber; S3, cutting the lubricated poly-lactic acid fiber into short fibers of multiple lengths; S4, using the poly-lactic acid fiber to manufacture lactic acid down. The degradable skin-friendly antibacterial lactic acid down manufacturing method and processing equipment use poly-lactic acid chips to spin poly-lactic acid fiber, then soak and lubricate the poly-lactic acid fiber, and mix and open the poly-lactic acid fiber short fibers of multiple lengths for carding. After the lustering process, the poly-lactic acid fiber is processed into lactic acid down. The lactic acid down is degradable and does not pollute the environment. The lactic acid down is a weakly acidic material, has skin-friendly and skin-protecting properties, antibacterial and anti-mite properties, and is non-allergic. In addition, the lactic acid down has a warmth retention performance similar to that of down.

[0004] To this end, Chinese patent application No. CN109930286A discloses a preparation method of polyester poly-lactic acid blended yarn simulated silk fabric. Polyester poly-lactic acid blended yarn and silk are used as warp and weft yarns.
