Problems solved by technology

Another example is CN201020594811.6, which discloses a sportswear knitted fabric, the lower layer of which is hollow polyester water-conducting fiber, and its surface layer obtains a hydrophobic effect by compounding a layer of PE film. This method has high production costs, complicated process conditions, and The outer layer is PE film, which will cause the fabric to feel bad, and the moisture permeability of the PE film is not very good, so the sweat cannot evaporate quickly after the body sweats, and the body will feel stuffy when sweating a lot

Embodiment 1

[0061] The outer coil is 75D-72f-PET yarn treated with hydrophobic resin, the middle coil is 20D-12f-PA yarn, and the inner coil is cotton yarn with a moisture regain of 8.5% and 50 counts, using a 24G Fukuhara double-sided machine Weaving, double-sided weave, weaves such as figure 1 , the horizontal and vertical density of the gray cloth is 35*43 pieces / inch, and the weight of the gray cloth is 145g / m 2 .

[0062] The gray cloth is finished by opening → gray cloth shaping → washing and scouring → dyeing → finishing and shaping. The shaping in this process is all wet cloth shaping, finishing and shaping can be properly added with resin according to needs to further improve the hand feeling; dyeing adopts the two-bath method: the first step The polyester component is dyed with disperse dye at 130°C, and the cotton component is dyed with direct dye at 60°C in the second step. Other processes are the same as conventional.

[0063] The obtained product has a horizontal and vert...

Embodiment 2

[0065] The outer coil is 50D-24f-PET yarn treated with hydrophobic resin, the middle coil is 20D-24f-ordinary PET yarn, and the inner coil is viscose yarn with a moisture regain of 13%, 50 counts and 20D- PU filaments are arranged in a ratio of 1:1, 24G Fukuhara double-sided machine weaving, double-sided weave, weave as figure 1 , the horizontal and vertical density of the gray cloth is 40*58 pieces / inch, and the weight of the gray cloth is 234.5g / m 2 .

[0066] The gray cloth is finished by opening → gray cloth shaping → washing and scouring → dyeing → finishing and shaping. The polyester component is dyed with disperse dye at 130°C, and the viscose component is dyed with direct dye at 60°C in the second step. Other processes are as usual.

[0067] The obtained product has a horizontal and vertical density of 41*64 pieces / inch, and a gram weight of 244g / m 2 . After washing 20 times, the water absorption time of the surface layer is more than 600 seconds, the water absorp...

Embodiment 3

[0069] The outer coil is 150D-72f-PET yarn treated with hydrophobic resin, the middle coil is 50D-24f-ordinary PET yarn, and the inner coil is cupro fiber yarn with a moisture regain of 13% and 50D. Fukuhara double-sided machine weaving, double-sided weaving, weaving such as figure 2 , the horizontal and vertical density of the gray cloth is 42*63 pieces / inch, and the weight of the gray cloth is 192g / m 2 .

[0070] The gray cloth is finished by opening → gray cloth shaping → washing and scouring → dyeing → finishing and shaping to obtain the finished product. In this process, the shaping is done with wet cloth. Resin can be added to further improve the hand feeling after finishing and shaping; two-bath method is used for dyeing PET and copper respectively. Ammonia dyeing. Other processes are as usual.

[0071] The obtained product has a horizontal and vertical density of 34*47 pieces / inch, and a gram weight of 137g / m 2 . The surface layer has good hydrophobic properties....

Abstract

The invention discloses compound tissue functionality knitted fabric. The compound tissue functionality knitted fabric is woven by at least two layers of knitted fabric of the outside and the inside, wherein the outside layer is a layer of polyester yarns which are treated by hydrophobic resins, and water absorption quick-dry yarns are contained in the inside layer. Compound tissue contexture is adopted. Finished products are obtained after greige cloth is passed through processes of the greige cloth forming, refining, coloring, forming and the like. A latter finishing process is simple and easy to control. The outside layer of the compound tissue functionality knitted fabric has good hydrophobic property, and the inside layer of the compound tissue functionality knitted fabric has good hydrophilic performance. The compound tissue functionality knitted fabric is soft in hand feeling, lasting in function and capable of being widely applied in sports underwear and coats and the like of all seasons.

Description

technical field [0001] The invention relates to a knitted fabric, in particular to a composite knitted fabric with a hydrophobic surface layer and a hydrophilic inner layer. The fabric can be used for various garments, especially sportswear fabrics. Background technique [0002] Currently on the market, the fabrics with surface hydrophobic and inner layer hydrophilic are mostly obtained by hydrophilic base cloth with hydrophobic resin impregnation or hydrophobic resin coating, or by filming, as disclosed in CN201110026818.7 A water-repellent, anti-fouling, moisture-absorbing and sweat-wicking composite knitted fabric and its production method, the outer layer of yarn is treated with a fluorine-containing water-repellent and anti-fouling treatment agent to obtain a hydrophobic effect, and the inner layer is treated with a hydrophilic finish The moisture-permeable yarn with special-shaped cross-section obtained by chemical treatment, and the middle layer is made of natural fib...
