Problems solved by technology

[0002] Polyester is a kind of chemical fiber clothing fabric raw material used in daily life. The biggest advantage of its fabric is that it has good wrinkle resistance and shape retention, but its moisture absorption and air permeability are poor. The fabric made of fabric is airtight, non-hygroscopic, and It is easy to generate static electricity due to friction, and it is particularly stuffy and uncomfortable to wear
With the development of economy and society, people's pursuit of beautiful clothes and increasing comfort requirements are constantly increasing. Polyester has good rigidity and good shape retention. The production of wool-like products can achieve a high degree of simulation of the appearance, but the problem of wearing comfort has always been restricted. with its further development

Abstract

The invention provides a two-component composite modified imitated fluff flash fiber and a preparation method thereof. After a first component and a second component are melted by a two-component composite spinning machine, the first component and the second component are guided to a first spinneret orifice and a second spinneret orifice through a first flow guide hole and a second flow guide hole in a distribution plate respectively, the first spinneret orifice comprises two parallel linear spinneret orifices, the second spinneret orifice is a cross spinneret orifice, the two parallel linear spinneret orifices are positioned in the upper side and the lower side of the cross spinneret orifice respectively, the first component and the second component are sprayed from the first spinneret orifice and the second spinneret orifice respectively and then cooled to form the two-component composite modified imitated fluff flash nascent fiber, and the two-component composite modified imitated fluff flash fiber is obtained after post-treatment. According to the preparation method for producing the two-component composite modified imitated fluff flash fiber, the application performance of polyester can be greatly improved only by modifying the polyester on an existing composite spinning device.

Description

technical field [0001] The invention relates to a kind of polyester chemical fiber filament for textile, in particular, when the fiber thread rotates or shakes, the optical effect of the special structure of the fiber makes the thread have a flashing effect, and the finished fabric has a highly imitated mohair, mink hair and other thin and short filaments. The invention discloses a two-component composite modified fiber with plush appearance and hand feeling and flash aesthetic effect, good moisture absorption, breathability, antistatic performance and wearing comfort, and a production method thereof. Background technique [0002] Polyester is a kind of chemical fiber clothing fabric raw material used in daily life. The biggest advantage of its fabric is that it has good wrinkle resistance and shape retention, but its moisture absorption and air permeability are poor. The fabric made of fabric is airtight, non-hygroscopic, and It is easy to generate static electricity due to...
