Problems solved by technology

[0002] At present, there are mainly two kinds of filling materials for thermal clothing other than down at home and abroad. One is sprayed cotton, which has the advantages of fluffy, good rebound, and thickness, but the disadvantage is that it feels rough and cannot be washed; the other is imitation cotton. Silk cotton, its advantage is that it feels delicate and soft, and it is used for high-end clothing. The disadvantage is that it has poor elasticity. The filling material of the same weight is only 40% of the thickness of sprayed cotton, and the price is relatively high.

Embodiment 1

[0014] Production 260g / m 2 Specification high elastic soft cotton. The ratio of raw materials is: 10% of polyester fiber with specification of 1.5De′×51mm; 20% of polyester fiber with specification of 1.8De′×64mm; 20% of polyester staple fiber with specification of 2.5De′×64mm; 27% of hollow fiber with specification of 3.33De′×64mm; 4De'×51mm specification low melting point fiber 13%. After the fibers are mixed, they are loosened and sent to the cotton box. After carding and laying, the upper and lower sides are sprayed with vinyl acetate copolymer emulsion accounting for 10% of the total, and sent to the dryer for drying. The temperature of the dryer is controlled at 150°C-175°C. Between, depending on the speed and temperature adjustment, the melting of low-melting-point fibers in the product and the drying of surface-adhesive latex shall prevail. The dried product is naturally cooled, then compressed and packaged.

Embodiment 2

[0016] Production 180g / m 2 Specification high elastic soft cotton. Raw material ratio: 1.5De′×51mm specification polyester fiber 15%; 1.8De′×64mm specification polyester fiber 20%; 2.5De′×64mm specification polyester fiber 17%; 3.33 De′×64mm specification hollow fiber 25%; 4De '×51mm specification low melting point fiber 14%. Spray vinyl acetate copolymer emulsion accounting for 9% of the total. The temperature of the dryer is controlled between 140-170°C. Its production process flow is identical with embodiment 1.

Embodiment 3

[0018] Production 80g / m 2 Specification high elastic soft cotton. Raw material ratio: 1.5De′×51mm polyester fiber 20%; 1.8De′×64mm polyester fiber 22%; 2.5De′×64mm polyester fiber 10%; 3.33De′×64mm hollow fiber 23%; 2De '×51mm specification low melting point fiber 17%. Spray the vinyl acetate copolymerization solution accounting for 8% of the total amount, and control the temperature of the dryer between 130-165°C. Its production process flow is identical with embodiment 1.

Abstract

The invention relates to a hi-elasticity soft cotton and a preparing way for the cotton, pertains to the technical field of chemical fiber. The hi-elasticity soft cotton is characterized in that, the cotton comprises microfibers of different sizes wrapping a layer of binding emulsion on surface. The microfibers are short polyester fiber, 3D hollow compound siliconized fiber, and compound fiber of low melting point. The binding emulsion is acetic-acid and ethylene copolymerized emulsion or propylene acetic-acid emulsion. The preparing of the hi-elasticity soft cotton comprises the following procedures: the short polyester fiber, 3D hollow compound siliconized fiber, and compound fiber of low melting point are mixed in different proportions fully, loosened, carded into net; on the upper and lower side of the cotton net, some binding emulsion is sprayed, then the cotton net is sent into a drier for drying, now the hi-elasticity soft cotton is obtained. The product is of high elasticity and bulkiness, touches fine and smooth, and the surface is flat; the product is resistant to water washing and will not deform, is of high value for spreading as a warming and filling material for hi-grade apparels.

Description

technical field [0001] The invention relates to high-elastic soft cotton and a production method thereof, belonging to the technical field of chemical fibers. Background technique [0002] At present, there are mainly two kinds of filling materials for thermal clothing other than down at home and abroad. One is sprayed cotton, which has the advantages of fluffy, good rebound, and thickness, but the disadvantage is that it feels rough and cannot be washed; the other is imitation cotton. Silk cotton has the advantages of fine and soft hand feeling, and is used for high-end clothing. The disadvantage is that it has poor elasticity. The filling material of the same weight is only 40% thick of the glued cotton, and the price is relatively high. Contents of the invention [0003] The object of the present invention is to provide a high-elastic soft cotton and its production method. The product can not only overcome the disadvantages of glued cotton and imitation silk cotton, but...
