Description

TECHNICAL FIELD The present invention relates to warp knitted fabrics and clothing that are excellent in wind resistance, stretchability, and elasticity.

The warp knitted fabric of the present invention comprises a composite yarn composed of two or more types of false twisted crimped yarn ("DTY") and having a torque of 30 T / m or less, and two components of side-by-side type or eccentric core-sheath type. Composite fibers are joined together and knitted together. At that time, in the composite yarn, the torque is preferably as small as possible, and non-torque (0 T/m) is most preferable. In order to make the yarn non-torque, it is preferable to form a composite yarn from a false twisted crimped yarn having torque in the S direction and a false twisted crimped yarn in the Z direction.

Here, the false-twisted crimped yarn is a so-called one-heater false-twisted crimped yarn, which is false-twisted in the first heater region, and the yarn is further introduced into the second heater region and subjected to the relaxation heat treatment.

At that time, a hydrophilizing agent (polyethylene terephthalate-polyethylene glycol copolymer) is added to the dyeing solution at a rate of 2 ml / liter, and the hydrophilizing agent is added to the warp knitted fabric by performing a bath treatment during the dyeing process. Granted. Then, the warp knitted fabric was subjected to dry heat final setting at a temperature of 160° C. for 1 minute. Table 1 shows the evaluation results.

[Comparative Example 2]
In Comparative Example 1, the same raw silk as in Example 4, which has a total fineness of 56 dtex/36 fibers, is raw silk made of composite fibers in which a polytrimethylene terephthalate (PTT) component and a polyethylene terephthalate (PET) component are joined side-by-side. The same procedure as in Comparative Example 1 was carried out except for the use. Table 1 shows the evaluation results.

[Comparative Example 3]
In Example 4, the procedure was the same as in Example 4, except that polyester false-twisted crimped yarn having a total fineness of 84 dtex/72 yarns (torque of 31 T/m or more) was used instead of the composite yarn. Table 1 shows the evaluation results.

[Comparative Example 4]
In Comparative Example 1, the same composite yarn (total fineness 66 dtex/72 yarns, crimp rate 35%, torque 30 T/m or less) as in Example 1 was supplied to two reeds, but the same procedure was performed as in Comparative Example 1. . Table 1 shows the evaluation results.

INDUSTRIAL APPLICABILITY According to the present invention, a warp-knitted fabric and clothing excellent in windproofness, stretchability and stiffness are provided, and their industrial value is extremely high.
