Abstract
Provided is a light polyester fiber with high gap, which is prepared by mixing, fusing and spinning water-soluble polyester having a proportion of 15% to 30% and ordinary polyester. The cross section of the fiber is at least one of a cross-shaped structure, a T-shaped structure, a Y-shaped structure, and an H-shaped structure. The radial profile degree DR is over 30%. The fiber has a large specific surface area, and the branching degree Ba=L2/s is over 18. The part from the fiber surface to the internal fiber is in a high-gap cellular state, and the density of the fiber is greatly reduced. The light polyester fiber with high gap can be prepared into various fluffy fiber products including DTY, BCF, BSY and others, and is suitable for producing casual clothing which is fluffy, light and comfortable.
Description
Technical field
The utility model relates to the slim and graceful polyester fiber of a kind of high-voidage, belongs to chemical fiber field.
Background technology
Polyester fiber is made by polyethylene terephthalate, and commodity are called terylene.It is the first kind of current synthetic fiber.Because the rigidity of fiber macromolecular chain is larger, elastic modelling quantity is high, and fiber is not yielding, after the fabric washing of its processing, does not wrinkle, and can not press, strongly very scrapes, easily washes easily dry.Also having good heat-resisting, cold-resistant, sun-proof and ABRASION RESISTANCE, is a kind of more satisfactory textile raw material.But polyester fiber is very fine and close, moisture absorption hardly, than great, Boardy Feeling, surface wax sense, easy pilling, the shortcomings such as antistatic difference; Being generally used for dress ornament can be uncomfortable.
Profiled filament is that the shape and structure that adopts physical method to change the chemical fibre cross section is realized.The cross section of profiled filament is more complicated, and the fibre section perimeter L is longer; The radially degree of profile DR(% of fiber) larger; The fibre section perimeter L is larger with the ratio of the long-pending S in fibre section, the branch degree Ba=L of fiber
2/ s is larger.The heteromorphosis of fibre section can cause a series of variations of fiber function.As large as the profiled filament specific area, interfibrous cohesive force is large, and lousiness is difficult for exposing, and the anti-fluffing and anti-pilling of fabric is good; Profiled filament specific area and voidage increase, and regain, hygroscopicity increase, thereby antistatic effect is good; Bulkiness, feel, gloss, the Color of fiber all can improve simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of have high degree of profile structure, dissolved water-soluble polyester from fiber surface to fibrous inside, stay the slim and graceful polyester fiber of the high-voidage that is the high-voidage state.This fiber is specially adapted to comfortable, fluffy, slim and graceful sportswear.
The utility model completes by following technical solution: the slim and graceful polyester fiber of a kind of high-voidage, described fiber is made by the water-soluble polyester blend melt spinning that adds 15% to 30% ratio in normal polyester, and the cross section of fiber is at least one in ten shapes, T shape, Y shape, H shape structure; It is degree of profile DR(% radially) be more than 30%; Fiber has than bigger serface, its branch degree Ba=L
2/ s is more than 18.
Described fiber surface to fibrous inside is high-voidage honeycomb state.
The utility model comprises the fluff type fiber species such as DTY, BCF, BSY, and through dissolving the water-soluble polyester of fiber surface to fibrous inside, fiber is the high-voidage state, and the density of fiber significantly descends; Fiber is applicable to make fluffy, slim and graceful, comfortable sportswear very much.
The accompanying drawing explanation
Fig. 1 is a kind of fiber cross section schematic diagram described in the utility model.
Fig. 2 is another kind of fiber cross section schematic diagram described in the utility model.
Fig. 3 is another fiber cross section schematic diagram described in the utility model.
Fig. 4 is another fiber cross section schematic diagram described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, the slim and graceful polyester fiber of high-voidage described in the utility model, the cross section of fiber is decussate texture; It is degree of profile DR(% radially) be more than 30%; Fiber has than bigger serface, its branch degree Ba=L
2/ s is more than 18.The surface of the slim and graceful polyester fiber of high-voidage to fibrous inside is the high-voidage state.Shown in Fig. 2, be that fiber cross section is Y-shaped structure; Shown in Fig. 3, be that fiber cross section is H shape structure; Shown in Fig. 4, be that fiber cross section is T shape structure; Their cross sections all are shape and the structure of high degree of profile.
Embodiment:
Spinning process described in the utility model is: on conventional spinning machine, add the water-soluble polyester blend melt spinning of 15% to 30% ratio in normal polyester, making cross section is the radially degree of profile DR(% such as ten shapes, T shape, Y shape, H shape) be more than 30%, branch degree Ba=L
2/ s is at least one the polymorphic structure fiber in the high degree of profile more than 18, makes fluff type fiber species such as comprising DTY, BCF, BSY.Then dissolve the water-soluble polyester of fiber surface to fibrous inside in boiling water solution, retain not dissolved normal polyester fiber and be high-voidage honeycomb state, the density of fiber significantly descends, and the performance of polyester fiber is significantly improved.
The slim and graceful polyester fiber of above-mentioned high-voidage is applicable to make fluffy, slim and graceful, comfortable sportswear very much.
Claims (2)
1. the slim and graceful polyester fiber of high-voidage, the cross section that it is characterized in that described fiber is at least one in ten shapes, T shape, Y shape, H shape structure; It is degree of profile DR(% radially) be more than 30%; Fiber has than bigger serface, its branch degree Ba=L
2/ s is more than 18.
2. the slim and graceful polyester fiber of high-voidage according to claim 1, is characterized in that described fiber surface to fibrous inside is high-voidage honeycomb state.
