Embodiment 1

[0075] Embodiment 1: a kind of production method of glue-free heat-bonded shaping special-shaped composite fiber,

[0076] The present invention is carried out on twin-screw composite spinning equipment and double-twist direction texturing machine, and the whole production process steps are as follows:

[0077] 1. Modification of raw materials for special-shaped skin layer 1. The general modified low-melting point polyester PET on the market cannot be elasticized. The low-melting point polyester PET must be re-modified and made by adding nucleating agent PPT plastic raw materials. The nucleating agent is re-modified and can crystallize quickly, and then the raw material is dried at a drying temperature of 80-100 degrees and a drying time of 8-12 hours. The water content is less than 50PPM.; the added amount of the nucleating agent PPT plastic raw material accounts for 5-20% of the total cortex raw material.

[0078] 2. Crystallize and dry the material of the special-shaped co...

Embodiment 2

[0084] Embodiment 2: Another production method of glue-free heat-bonding shaped special-shaped composite fiber,

[0085] The present invention is carried out on twin-screw composite spinning equipment and double-twist direction texturing machine, and the whole production process steps are as follows:

[0086] 1. Modification of raw materials for special-shaped skin layer 1. The general modified low-melting point polyester PET on the market cannot be elasticized. The low-melting point polyester PET must be re-modified and made by adding nucleating agent PPT plastic raw materials. The nucleating agent is re-modified and can crystallize quickly, and then the raw material is dried at a drying temperature of 80-100 degrees and a drying time of 8-12 hours.

Abstract

The invention provides a profiled composite fiber free from heat bonding and heat setting with an adhesive and a production method and application thereof, relates to a profiled composite elastic fiber material free from heat bonding forming with an adhesive and a production method and application thereof, and can be applied to the fields of making a fiber nib, a water storage core, an oil storagecore, an ink storage core, a water diversion core, a water absorption rod, a fragrant rod, an environmentally-friendly water treatment filter film, a filter rod, filter and oil storage materials of other industries, volatile materials, etc. The profiled composite fiber free from heat bonding and heat setting with the adhesive is composed of a profiled skin layer and a profiled core layer, whereinthe profiled skin layer is wrapped outside the profiled core layer, and the profiled skin layer and the profiled core layer are composited into the profiled composite fiber through composite spinningcomponent and a spinneret plate. The profiled skin layer and the profiled core layer are spun to produce various combinations of profiled skin / core composite fibers of various shapes through the spinneret plate of textile equipment by using polymer materials with different properties. The shapes of the are arranged as a + shape, a shape like the Chinese character 'mi', a Y shape, a five-pointed star shape or a composite polygon.
