Abstract
The utility model relates to a polyester chemical fiber material and discloses skin-core type regenerated polyester staple fiber with a low melting point. The fineness of the polyester staple fiber is 2.0dtex-5.0dtex and the length of the polyester staple fiber is 10mm-80mm; the polyester staple fiber is composed of a skin layer and a core layer in the diameter direction, wherein the core layer is completely packaged in the skin layer; the diameter of the core layer is 0.5-0.9 times that of the staple fiber; the skin layer is made from the polyester material with the melting point of 70 DEG C-160 DEG C; and the core layer is made from the regenerated polyester material with the melting point of 250 DEG C-270 DEG C. By adopting the technical scheme, the skin-core type regenerated polyester staple fiber with the low melting point can be used for improving the additional value of preparing the regenerated polyester staple fiber by the polyester waste material; the skin-core type regenerated polyester staple fiber with the low melting point has the characteristics of being stable in quality and excellent in quality.
Description
Technical field
The utility model relates to a kind of polyesterification fiber material.
Background technology
Low melting point core-skin type complex polyester staple fibre refers to be distributed in the fiber of making among the same fiber with skin-core structure with these two kinds of different polymer of low-melting point polyester and normal polyester.Cortex is low-melting point polyester, and it has kept the part characteristic of normal polyester, has the characteristics of good compatibility with normal polyester.The low melting point core-skin composite fiber is mainly used in heat-bondable fiber, and main effect is low-melting fiber cortex polymer fusing at a certain temperature in non-weaving cloth production, coheres effect thereby play in fiber web.Because the low melt point polyester fiber staple fibre has the intensity height, bulkiness is good, elastic restoration ratio is high, characteristics such as that the non-weaving cloth of producing has is soft, elasticity height are widely used in fields such as hygienic material such as surgical mask, bandage and house decorative material at present.
Along with polyester material developing rapidly and using in each field, the discharge capacity of polyester waste material grows with each passing day, its refractory organics has now caused great pollution to environment, and because the present shortage of the raw material of industry, and the recycling of polyester waste material has been become the required of sustainable development society.Most of for low additional fields such as fillers with the staple fibre of polyester waste material preparation at present.Study modified accent adhering process, solve that the polyester waste material source is wide, complicated component, technical barrier that quality fluctuation is big, utilize the polyester waste material preparation to have the key subjects that high value-added product becomes upgrading transition of regeneration industry.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the purpose of this utility model is to provide a kind of sheath-core type low-melting point regenerative polyester staple fiber, improved the added value that polyester waste material prepares regenerative polyester staple fiber, the sheath-core type low-melting point regenerative polyester staple fiber has steady quality, colory characteristics.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
The sheath-core type low-melting point regenerative polyester staple fiber, the fineness of this polyester staple fiber is 2.0 ~ 5.0dtex, length is 10 ~ 80mm, polyester staple fiber is made of cortex and sandwich layer on diametric(al), sandwich layer is completely wrapped in the cortex, the diameter of sandwich layer is 0.5 ~ 0.9 times of staple fibre diameter, and described cortex is that fusing point is 70～160 ℃ polyester material, and it is 250～270 ℃ of recycled polyester materials that described sandwich layer adopts fusing point.
The fusing point that the utility model relates to is that 70～160 ℃ polyester material and fusing point is that 250～270 ℃ of recycled polyester materials are existing material.
As preferably, the fineness of described polyester staple fiber is 2.5 ~ 4.0 dtex, and length is 32 ~ 64mm.
As preferably, the diameter of described sandwich layer is 0.7 ~ 0.8 times of staple fibre diameter.
The utility model has been owing to adopted above-mentioned technical scheme, improved the added value that polyester waste material prepares regenerative polyester staple fiber, and the sheath-core type low-melting point regenerative polyester staple fiber has steady quality, colory characteristics.Can be used for producing in the industries such as non-weaving cloth, flocking, composite.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
Sheath-core type low-melting point regenerative polyester staple fiber as shown in Figure 1, the fineness of the polyester staple fiber of this polyester staple fiber is 2.5 ~ 4.0 dtex, length is 32 ~ 64mm, polyester staple fiber is made of cortex 1 and sandwich layer 2 on diametric(al), sandwich layer 2 is completely wrapped in the cortex 1, the diameter of sandwich layer 2 is 0.7 ~ 0.8 times of staple fibre diameter, and described cortex 1 is 70～160 ℃ polyester material for fusing point, and it is 250～270 ℃ of recycled polyester materials that described sandwich layer 2 adopts fusing points.
