Abstract
The utility model discloses a black brightening recycled polyester short fiber, which aims to resolve the problem of the conventional black fiber that the color is not strong. The utility model is characterized in that section of the short fiber is in a three-blade shape; the included angle of two adjacent blades of the three-blade-shaped section is 120 DEG; the ratio of the length and the width of the blade is in 1:5. The utility model is advantageous in that with a plurality of reflecting surfaces, the black fiber is good in color and strong in brightness; the recycled polyester bottle flakes are adopted, thereby recycling of waste is realized which protects the environment and saves energy and suits for a sustainable development.
Description
Technical field
The utility model relates to a kind of profiled fibre, particularly a kind of regenerative polyester staple fiber with black increment effect.
Background technology
In recent years, along with nonwoven fabric and fabrics for industrial use developing rapidly in the international market, also more and more vigorous to the demand of colored fibre.Because have complex process in traditional dyeing and finishing technology, problems such as colouring is inhomogeneous, color and luster is not bright-coloured, fugitive color and environmental pollution, arise at the historic moment so the employing color grain carries out the technology that original liquid coloring directly is spun into colored fibre.Painted before original liquid coloring claims again to spin, different with traditional dyeing mechanism, the former is evenly dispersed in the condensate colouring agent, is promptly anchored in the fiber through the agent of spinning technique after stain, and coloring process belongs to physical change; The latter dyes after being spun into fiber again, requires dyestuff or pigment and condensate that certain adhesion and affinity are arranged, and dyeing course mainly belongs to chemical change.Paintedly before spinning carry out in fiber production factory, traditional dyeing then carries out in textile mills or printing and dyeing mill.Producer-coloured fibre has not only fundamentally solved the problem of traditional dyeing and finishing technology, and has simplified technological process greatly, reduced production cost, environmental protection is played a part positive.The pigmented polyester staple fibre has been widely used in various nonwoven fabric and fabrics for industrial use fields such as automotive trim, household textiles, footwear material, move materials before spinning at present.As a kind of emerging product, the producer-coloured fibre major part can both be advantageously applied to textile mills, but exist some problems identical with traditional dyeing on the color and luster degree: dull fiber especially black fiber color and luster is not strong all the time, always gives the gloomy sensation of people.Have in the market by chemical spraying process to strengthen color and luster, also have padding method to strengthen color and luster, but like this increased cost and manufacturing procedure.
Chinese patent notification number CN201406488Y, February 17 2010 day for announcing, announced a kind of core-skin type colored fibre, comprised cortex and sandwich layer, sandwich layer is painted, the cross section of core-skin type colored fibre is circular, this fiber is applicable to hygienic material, can prevent skin sensitivity, but the sandwich layer of this colored fibre is to adopt color grain to carry out original liquid coloring to be spun into, when making the sandwich layer of black, color and luster is not strong.
Summary of the invention
The purpose of this utility model is to solve the existing not strong problem of black fiber color and luster, a kind of regenerative polyester staple fiber of trifoil cross-section is provided, it has a plurality of reflectings surface, make that color and luster behind the black fiber is good, brightness is high, it adopts regenerative piece of polyester bottle is raw material, having realized the utilization again of refuse, environmental protection, economized on resources, is a kind of product of sustainable development.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of black brightened type regenerative polyester staple fiber, the cross section of described regenerative polyester staple fiber is a trilobal.The cross section of regenerative polyester staple fiber is a trilobal, the regenerative polyester staple fiber of this trifoil cross-section, have a plurality of reflectings surface, guaranteed good light reflecting effect, can strengthen the color and luster of black fiber, the black regenerative polyester staple fiber color and luster of making is good, brightness is high, it adopts regenerative piece of polyester bottle is raw material, having realized the utilization again of refuse, environmental protection, economized on resources, is a kind of product of sustainable development; Regenerative polyester staple fiber of the present utility model adopts existing spray silk technology all can make.
As preferably, the angle between the adjacent blade face of trifoil cross-section is 120 degree.Three blade faces of trifoil cross-section evenly distribute in same circle, and the angle between the adjacent blade face is 120 degree, and the light reflecting effect is good.
As preferably, the blade face of trifoil cross-section is rectangle, and three blade faces of trifoil cross-section etc. are big.Be provided with like this and be convenient to processing, reflecting surface is bigger, and the light reflecting effect is good, and the black regenerative polyester staple fiber color and luster of making is good, brightness is high.
As preferably, outer, the blade face arc transition of trifoil cross-section.Outer, blade face arc transition can reduce the stress at place, outer, blade face like this and concentrate, and increases the structural strength on blade face, can make that also the regenerative polyester staple fiber feel is soft.
As preferably, the length on the blade face of trifoil cross-section and width are than being 1:3 ~ 7.The length and the width on blade face rationally are set, can guarantee good fiber reflection effect, feasible good, the brightness of black regenerative polyester staple fiber color and luster of making.
As preferably, the length on the blade face of trifoil cross-section and width are than being 1:5.Under this length-width ratio, the fiber reflection best results.
As preferably, the fineness of described regenerative polyester staple fiber was 3 dawn ~ 18 dawn.When regenerative polyester staple fiber has the trifoil cross-section, the cross section is wide more, length of blade is long more, the light reflecting effect is good more, but the cross section is wide more, and fiber is thick more, the fabric feeling of being made by this fiber is harder, sense of fullness is not strong, takes all factors into consideration, and the reasonable value of regenerative polyester staple fiber fineness is in 3 dawn ~ 18 between the dawn; It is that the trifoil cross-section regenerative polyester staple fiber at 3 dawn ~ 6 dawn is a raw material that general clothes or other require soft fabric to adopt fineness, and it is that the trifoil cross-section regenerative polyester staple fiber at 6 dawn ~ 18 dawn is a raw material that industry adopts fineness with, technology with textiles.
The beneficial effects of the utility model are: the cross section of regenerative polyester staple fiber is a trilobal, angle between the adjacent blade face of trifoil cross-section is 120 degree, the length on the blade face of trifoil cross-section is 1:5 with the width ratio, the regenerative polyester staple fiber of this trifoil cross-section, have a plurality of reflectings surface, guaranteed good light reflecting effect, can strengthen the color and luster of black fiber, the black regenerative polyester staple fiber color and luster of making is good, the brightness height, it adopts regenerative piece of polyester bottle is raw material, realized the utilization again of refuse, environmental protection, economizing on resources, is a kind of product of sustainable development.
