Problems solved by technology

[0002] Although conventional polyester used as clothing fabric has the advantages of high strength, easy washing and drying, etc., due to its poor moisture absorption and air permeability and high density, the fabric made of fabric is airtight and non-hygroscopic, and is prone to static electricity due to friction, making it heavy and wet. , poor comfort
With the improvement of social economy and living standards, people's requirements for beautiful and comfortable clothes are constantly increasing, and the defects of polyester itself restrict the development of its application to a large extent.

Embodiment 1

[0033] A two-component special-shaped hollow high-moisture-absorbing crimped composite fiber is made by using polyester and bio-based polyamide 56 with a mass ratio of 50:50 and adding adhesives through "8"-shaped spinneret holes. The dry heat shrinkage rate of the polyester is 5%, and the boiling water shrinkage rate is 7%. The dry heat shrinkage rate of the bio-based nylon 56 is 6%, and the boiling water shrinkage rate is 8%. The hollowness of the composite fiber is 20%. The added amount of the binder is 6% of the total mass of the composite fiber.

[0034] Such as figure 1 As shown, the "8"-shaped spinneret hole is composed of the first "O"-shaped structure spinneret 01 and the second "O"-shaped structure spinneret 02, the first spinneret 01 and the second spinneret Holes 02 are arranged side by side to form an "8"-shaped structure. The first "O"-shaped structure spinneret 01 and the second "O"-shaped structure spinneret 02 are fixedly connected, and the first "O"-shape...

Embodiment 2

[0039] A two-component special-shaped hollow high-moisture-absorbing curly composite fiber, which is a modified polyamide with a mass ratio of 80:20 of polyester and bio-based polyamide 56, which is a group that can react with both polyester and polyamide, and an adhesive is added. Made through "8"-shaped spinneret holes. The dry heat shrinkage rate of the polyester is 7%, and the boiling water shrinkage rate is 9%. The dry heat shrinkage rate of the bio-based nylon 56 is 12%, and the boiling water shrinkage rate is 20%. The hollowness of the composite fiber is 25%. The added amount of the binder is 10% of the total mass of the composite fiber.

[0040] Such as figure 1 As shown, the "8"-shaped spinneret hole is composed of the first "O"-shaped structure spinneret 01 and the second "O"-shaped structure spinneret 02, the first spinneret 01 and the second spinneret Holes 02 are arranged side by side to form an "8"-shaped structure. The first "O"-shaped structure spinneret 0...

Embodiment 3

[0044] A two-component special-shaped hollow high-moisture-absorbing crimped composite fiber is prepared by using polyester and bio-based polyamide 56 with a mass ratio of 70:30 and adding adhesives through "8"-shaped spinneret holes. The dry heat shrinkage rate of the polyester is 8%, and the boiling water shrinkage rate is 11%. The dry heat shrinkage rate of the bio-based nylon 56 is 18%, and the boiling water shrinkage rate is 30%. The hollowness of the composite fiber is 22%. The added amount of the binder is 7% of the total mass of the composite fiber.

[0045] Such as figure 1 As shown, the "8"-shaped spinneret hole is composed of the first "O"-shaped structure spinneret 01 and the second "O"-shaped structure spinneret 02, the first spinneret 01 and the second spinneret Holes 02 are arranged side by side to form an "8"-shaped structure. The first "O"-shaped structure spinneret 01 and the second "O"-shaped structure spinneret 02 are fixedly connected, and the first "O...

Abstract

The invention provides a two-component abnormity hollow high moisture absorption curling composite fiber and a preparation method thereof; the preparation method comprises the following steps: spinning on a two-component composite spinning machine; enabling terylene melt to pass a first diversion hole of a first diversion slot on a melt distributing board, and to enter a first O-shape spinneret hole of a 8-shape spinneret hole; enabling polyamide 56 melt to pass a second diversion hole of a second diversion slot on the melt distributing board, and to enter a second O-shape spinneret hole of the 8-shape spinneret hole; using a bonding agent to firmly bond the melt flowing from the first and second O-shape spinneret holes into one body; using a side blowing mode to cool off the melt so as to obtain nascent fiber; carrying out post-treatment so as to obtain the two-component abnormity hollow high moisture absorption curling composite fiber. Finished product fabrics using the two-component abnormity hollow high moisture absorption curling composite fiber and the method has good moisture absorbable and breathable effect, is ventilating, anti-static, hollow, and warming.

Description

technical field [0001] The invention belongs to the field of polyester composite fibers, in particular to a double-component special-shaped hollow high-moisture-absorbing curly composite fiber and a preparation method thereof. Background technique [0002] Although conventional polyester used as clothing fabric has the advantages of high strength, easy washing and drying, etc., due to its poor moisture absorption and air permeability and high density, the fabric made of fabric is airtight and non-hygroscopic, and is prone to static electricity due to friction, making it heavy and wet. , poor comfort. With the improvement of social economy and living standards, people's requirements for beautiful and comfortable clothes are constantly increasing, and the defects of polyester itself restrict the development of its application to a large extent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a two-component specia...
