Abstract
The utility model relates to a warm-keeping hot air non-woven fabric, which effectively solves the problems that the warm-keeping performance of hot air non-woven fabric is poor, the softness and the comfort are to be improved, and the consumption of a spinning material is large; the technical scheme is that: the fiber comprises a hollow layer, a middle layer and a surface layer from inside to outside, wherein the hollow layer is a cavity extending along the axis of the fiber, the cross section of the cavity is circular or irregular, the middle layer is made of polyester PET material, the layer is a main core layer of the fiber, and the surface layer is made of low-melting-point polyethylene PE material or polypropylene PP material; according to the utility model, the hollow layer is arranged in the middle, so that the fabric formed by the fiber has good warmth retention property and fluffy softness, has lighter quality and saves raw materials.
Description
Technical Field
The utility model relates to the field of composite fibers, in particular to a warm-keeping hot air non-woven fabric.
Background
The hot air non-woven fabric is a raw material for forming the hot air non-woven fabric, the surface layers of the fibers are melted and mutually bonded under hot air to form cloth, and most of the current hot air non-woven fabric is solid, so that the hot air non-woven fabric has poor warmth retention property, the softness and the comfort are to be improved, and the consumption of the spinning material is large.
Disclosure of Invention
The utility model provides a warm-keeping hot air non-woven fabric, which is used for solving the problems that the warm-keeping performance of hot air non-woven fabric is poor, the softness and the comfort are to be improved, and the consumption of a spinning material is large.
The technical scheme for solving the problems is as follows: the three-layer composite cloth comprises three layers of hot air cloth, wherein a first layer and a third layer of the cloth are hot air cloth, a second layer of the cloth is formed by combing hollow fibers into directional arrangement and then is bonded with the first layer and the third layer through hot air, the hollow fibers comprise a three-layer structure, the hollow fibers comprise a hollow layer, a middle layer and a surface layer from inside to outside, the hollow layer is a cavity extending along the axis of the fibers, the cross section of the cavity is circular or irregularly shaped, the middle layer is made of a polyester PET material, the layer is a main core layer of the hollow fibers, and the surface layer is made of a low-melting-point polyethylene PE material or a polypropylene PP material.
According to the utility model, the hollow layer is arranged in the middle, so that the fabric formed by the fiber has good warmth retention property and fluffy softness, has lighter quality and saves raw materials.
Drawings
FIG. 1 is a cross-sectional view of a hollow fiber.
Detailed Description
In combination with the attached drawings, the hollow fiber of the utility model sequentially comprises a hollow layer 1, a middle layer 2 and a surface layer 3 from inside to outside, wherein the hollow layer 1 is a cavity extending along the axis of the hollow fiber, the cross section of the cavity is circular or irregular, the irregular shape can be zigzag, clover, pentagram and the like, the specific cavity shape is determined by the shape of a spinneret, the middle layer 2 is made of polyester PET material, the layer is a main core layer of the hollow fiber, the hollow layer 1 is arranged at the axis of the middle layer 2, the hollow layer 1 is integrally formed through a spinneret orifice during spinning, and the surface layer 3 is made of low-melting polyethylene PE material or polypropylene PP material and is used for hot air melting bonding.
The utility model can form non-woven cloth after hot air bonding, and also can form composite layer cloth with other cloth, for example, the first layer of cloth is made of hot air, the middle layer of cloth is made of hollow fiber after carding by a carding machine to form directional arrangement, the third layer of cloth is made of hot air, and then three layers of composite cloth are formed through hot air bonding; the cloth formed by the hollow fibers can be used for mask fabrics, thermal fabrics and the like.
According to the utility model, the hollow layer 1 is arranged in the middle of the hollow fiber, so that the cloth formed by the hollow fiber has good heat insulation performance and fluffy softness, has lighter weight and saves raw materials.
Claims (1)
1. The utility model provides a cold-proof hot-blast non-woven fabrics, its characterized in that includes three-layer composite cloth, the first layer and the third layer of cloth are hot-blast cloth, the second layer of cloth is carded into directional arrangement by hollow fiber and is glued with first layer and third layer through hot-blast, hollow fiber include three layer construction, from inside to outside be hollow layer (1), intermediate level (2) and top layer (3) in proper order, hollow layer (1) is the cavity that extends along the fibre axis, the cavity cross-section is circular or irregular shape, intermediate level (2) are polyester PET material, this layer is hollow fiber's main part sandwich layer, top layer (3) are low-melting polyethylene PE material or polypropylene PP material.
