Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0010] Such as figure 1 , figure 2 As shown, the different shrinkage composite fiber of the present invention is composed of FDY fiber filaments and POY fiber filaments through network plying, and its characteristics are: the cross section of the FDY fiber filaments is an island-in-the-sea type; the POY fiber filaments The cross-section is an orange segment with a "rice" structure. And: the cross-section of the FDY fiber is an island-in-the-sea type in which the island component 1 is polyester—PET for short, and the sea component 2 is water-soluble polyester—COPET for short; the cross section of the POY fiber It is an orange petal shape with a "rice" structure, in which component 4 of the "rice" character is water-soluble polyester - COPET for short, and component 3 embedded in the "rice" structure is polyester - PET for short .

Abstract

The invention discloses a differential shrinkage composite fiber which is composed of FDY (fully draw yarn) fiber yarn and POY (partially oriented yarn) fiber yarn by network stranding, and is characterized in that: the cross section of the FDY fiber yarn is of a sea island shape composed of polyester as an island component and water-soluble polyester as a sea component; and the cross section of the POY fiber yarn is of an orange valve shape in a structure as shown in Chinese character 'Mi', the component forming the Chinese character 'Mi' is the water-soluble polyester, and the component embedded in the Chinese character 'Mi' is the polyester. Because the FDY with a sea-island-shaped section and the POY with an orange-valve-shaped section are introduced to the differential shrinkage composite fiber, after splitting, the composite fiber has superfine monofilament titer; and after the superfine differential shrinkage composite fiber is treated by downstream splitting, the monofilament titer can reach 0.08dtex, the fiber monofilament titer reaches the superfine effect, and the fabric has soft hand feeling and excellent woolen feeling.

Description

technical field [0001] The invention relates to a composite fiber with different shrinkage. Background technique [0002] Existing different-shrinkage composite fibers are mainly composed of single-component FDY yarns and single-component POY yarns that are bonded through a network, and the cross-section of the single-component finished yarn is a single-component cross-section. The different-shrinkage composite fiber with this cross-sectional structure has a monofilament fineness greater than 0.3dtex, does not have the characteristics of ultra-fine fibers, and has poor effects on fabric velvet and softness, which in turn affects the functional use of the different-shrinkage composite fiber. Contents of the invention [0003] The purpose of the present invention is to provide a different shrinkage composite fiber with excellent effects in fabric velvet feeling and softness. [0004] In order to achieve the above object, the technical solution adopted by the present inventi...
