Example 1:
The first yarn Y 1 adopts common polyester with C-shaped section, PES 80D/144F, and the second yarn Y 2 adopts common polyester with circular section, PES 30D/24F. The two yarns are interwoven to form a fabric body, and the weft knitting single-sided plain weave is formed. The fabric body is provided with a clothing surface and a skin-adhering surface, the clothing surface is formed by a looping and tucking structure, and the first yarn Y 1 and the second yarn Y 2 are woven to form the clothing surface. The skin-adhering surface is composed of a looping and collecting loop or floating line structure. The second yarn Y 2 is knitted on the skin surface to form a non-looping knitting unit, and the first yarn Y 1 is exposed on the skin surface to form a geometric discontinuous raised area. In a unit circulation structure, two first yarns Y 1 and one second yarn Y 2 are formed, m=2, and n=1.
In this embodiment, as shown in FIGS. 1 to 3, the coverage area S B＝2S1Y1+S2y2 W of the skin-facing yarn is equal to the coverage area S F＝2S2y1+S2y2 of the knitted fabric clothing face yarn.
The equivalent radius of the terylene monofilament of the first yarn Y 1 (80D/144F) is as follows:
DY1=2×3.80=7.6(μm)
Similarly, we calculated the second yarn Y 2 (30D/24F) as having an equivalent radius of polyester monofilament of:
DY2=2×5.70=11.4(μm)
In summary, the coverage area of the skin-facing yarns of the knitted fabric in a unit circulation weave structure
The knitted fabric has a covering area S of the face yarn of the garment in a unit cycle weave structure F＝2S2Y1+S2Y2＝6.928DY1 2×2+6.928DY2 2
=1700.69μm2
Thereby, S F：SB =1.39.
In this example the first yarn Y 1 (contact angle 55 ° and the second yarn Y 2 contact angle 63 °) was measured according to the standard AATCC 195"Liquid Moisture Management Properties of Textile Fabrics liquid moisture management performance of the textile.
Comparative example 1:
The first yarn Y 1 and the second yarn Y 2 are interwoven by adopting common polyester (PES 80D/144F) to form weft-knitted single-sided plain fabric, and the contact angle is 55 degrees. Also, in a unit cycle structure, two first yarns Y 1 and one second yarn Y 2 are formed. The knitted fabric described above was measured for liquid moisture management properties "according to standard AATCC 195"Liquid Moisture Management Properties of Textile Fabrics textile. The unidirectional moisture permeability OWTC (one way transport capability) of the fabric is measured to be 80%.
Compared with the fabric, the fabric is light, thin and soft by modifying the structure and the yarn count of the fabric, the unidirectional moisture-conducting capacity of the fabric is greatly improved, and the dryness and comfort of the skin-facing surface of the fabric body can be kept for a long time.
Example 2:
Based on example 1, 150D/288F polyester was used as the first yarn Y 1 and 40D/36F polypropylene was used as the second yarn Y 2. The two yarns are interwoven to form a fabric body, and napping treatment is carried out. The second yarn Y 2 is the yarn of the non-loop knitting unit of the skin surface, and the first yarn Y 1 is exposed on the skin surface and is a geometrically discontinuous raised area. The clothing surface is of jacquard structure, and the skin-adhering surface is provided with a fluff area. In a unit circulation structure, two first yarns Y 1 and one second yarn Y 2 are formed, m=2, and n=1.
In this example, the coverage area S B＝2S1Y1+S2y2 W of the skin-facing yarn was found to be the coverage area S F＝2S2y1+S2y2 of the knitted fabric clothing face yarn.
The equivalent radius of the terylene monofilament of the first yarn Y 1 (150D/288F) is as follows:
DY1=2×3.16=6.32(μm)
Similarly, we calculated the second yarn Y 2 (40D/36F) as having a polypropylene monofilament equivalent radius of:
DY2=2×4.47=8.94(μm)
in summary, the invention relates to the coverage area of the skin-facing yarn in a unit circulation organization structure
The invention covers the surface yarn S in a unit circulation organization structure F＝2S2Y1+S2Y2＝6.928DY1 2×2+6.928DY2 2
=1107.15μm2
Thereby, S F：SB =1.34.
The contact angle of the first yarn Y 1 in this example is 58 ° and the contact angle of the second yarn Y 2 is 71 °. The knitted fabric was measured for liquid moisture management properties of standard AATCC 195"Liquid Moisture Management Properties of Textile Fabrics textiles. The unidirectional moisture-conducting capacity OWTC (one way transport capability) of the fabric body measured this time is 320%.
