Detailed Description

The utility model is further described with reference to the following figures and specific examples.

Example one

This embodiment will be described in detail with reference to fig. 1 and 2. The anti-pilling antibacterial wool yarn comprises a worsted wool yarn 1 and a carded wool composite yarn 2 which are twisted with each other; the woolen wool composite yarn comprises a twisted woolen wool yarn 21 and a two-component polylactic acid yarn 22; the bicomponent polylactic acid fiber used by the bicomponent polylactic acid yarn 22 is a sheath-core polylactic acid fiber, and the sheath-core polylactic acid fiber comprises a sheath layer 221 and a core layer 222; the skin layer 221 is low-melting-point polylactic acid, and the core layer 222 is high-melting-point polylactic acid.

Corn fiber CornFiber (polylactic acid PLA fiber) is a bio-based chemically synthesized fiber which is prepared by taking starch extracted from old corn, cassava, straws and other plants as raw materials, converting the starch into lactic acid through fermentation, polymerizing and spinning. In recent years, corn fiber has become a subject of attention in the textile and clothing industry. The whole production process of the corn fiber is harmless to the environment and has no pollution. Meanwhile, the fiber has good biodegradability, and if the fiber is buried in compost after being discarded, the fiber can be degraded into carbon dioxide and water after a plurality of months, returns to the nature and does not pollute the environment. The fiber is renewable in resources, has good biocompatibility and biological absorbability, and is a novel natural functional textile material with full ecological and environmental protection. The polylactic acid fiber has the effects of keeping sterilization and inhibiting bacterial reproduction for a long time, has the functions of eliminating peculiar smell and self-cleaning dirt, and has good air permeability.

Furthermore, in the present embodiment, the melting point of the low-melting polylactic acid is 125-135 ℃; the melting point of the high-melting-point polylactic acid is 170-180 ℃; the volume ratio of the skin layer 221 to the core layer 222 is 30-50: 50-70 parts of; the length of the polylactic acid fiber is 32-38mm, and the linear density of the fiber is 1.5D-4D.
