Abstract

The invention discloses a high-shrinkage ultrafine polyester-polyamide composite fiber which comprises an ultrafine polyester-polyamide composite fiber, wherein the ultrafine polyester-polyamide composite fiber is formed in a manner that an ultrafine modified polyester fiber serves as a core wire and a modified nylon fiber layer is coated outside the ultrafine modified polyester fiber, and the ultrafine modified polyester fiber core wire is characterized in that the polyester fiber contains a polyurethane and silicon dioxide nano-powder material; and the modified nylon fiber layer is characterized in that nylon 6 contains a Vistamaxx propenyl elastomer. The high-shrinkage ultrafine polyester-polyamide composite fiber obtained through the production method disclosed by the invention has good fiber properties of both the polyester fiber and polyamide fiber and embodies the elastic functions of polyurethane and the Vistamaxx propenyl elastomer; shown by experimental tests, the elastic recovery ratio is 100% when the elongation percentage is 10%; and furthermore, the strength of the composite fiber reaches 7.5-8.0 cN/dtex.

Description

technical field [0001] The invention relates to a fiber production technology, in particular to a high-shrinkage polyester nylon composite superfine fiber and a production method. Background technique [0002] Polyester-nylon composite superfine fiber is often limited by the material properties of polyester and nylon, and the shrinkage rate of the composite fiber is also affected to a certain extent. It is often impossible to produce a composite fiber with a high shrinkage rate, which brings certain limitations to its application. Contents of the invention [0003] The object of the present invention is to provide a high-shrinkage polyester-nylon composite superfine fiber and a production method that not only have a high shrinkage rate but also have the characteristics of the fiber itself in order to solve the above-mentioned deficiencies in the prior art. [0004] In order to achieve the above object, the present invention provides a high-shrinkage polyester nylon composi...
