Problems solved by technology

With this form of fiber cross-section, "wedge" type ultra-fine fibers can be obtained after stripping. Each single fiber has 3 sharp corners. It has a good cleaning effect and can be used as a wiping cloth. However, due to its special cross-sectional shape, It has higher requirements on the compatibility between the fiber base material and the modifier. If the compatibility between the fiber base material and the modifier is not good, it will easily lead to poor fiber dyeing

Abstract

The invention relates to a split-orange-slice-shaped polyethylene terephthalate (PET) fiber containing metal modified crossed compound ester and a preparation method of the split-orange-slice-shaped PET fiber. The preparation method comprises the steps that a spinning melt prepared from functional master batch containing the metal modified crossed compound ester and polyester chips in melted and blended mode is extruded from split-orange-slice-shaped spinneret holes to form the split-orange-slice-shaped PET fiber containing the metal modified crossed compound ester, wherein the metal modifiedcrossed compound ester is porous microspheres and is prepared in the mode that a crossed hybrid is nucleated and grows to form the microspheres, and then hole forming is conducted, and the molecular structural formula of the crossed hybrid is mainly constituted by crossed esterified ester molecules, chain molecules with amino and metal ions M<n+>. The section of the prepared PET fiber is in a split-orange-slice shape. The wicking height of a fabric prepared from the split-orange-slice-shaped PET fiber containing the metal modified crossed compound ester within 10 min is 1400-2600 mm. The preparation method of the split-orange-slice-shaped PET fiber is simple in process and low in cost, and a product prepared through the preparation method is excellent in processing performance, excellent in flame-retardant and antibacterial performance and good in market prospect.

Description

technical field [0001] The invention belongs to the technical field of functional fibers, and relates to a petal-orange-shaped PET fiber containing a metal-modified cross-shaped esterified product and a preparation method. Background technique [0002] With the continuous improvement of people's living standards, people have put forward higher requirements for the comfort, functionality, diversification and taste of clothing. Functional fibers, differential fibers and high-performance fibers are the main development directions of the current traditional textile industry technology innovation. Functional fiber refers to a new type of fiber that has some special function in addition to the physical and mechanical properties of ordinary fibers. In order to increase the added value of fibers, the functionalization and differentiation of fibers is an inevitable requirement of the industry. Fiber functionalization has become a hot research direction in the fiber field. [0003]...
