Method for manufacturing tricot brushed fabric for clothing using 2-Bar warp knitted fabric and brushed fabric

The present invention relates to a method for manufacturing a 1 mm tricot raised fabric for clothing using a 2-bar warp knitted fabric and a raised fabric therefor.

Existing suits made of woven materials are heavy and inflexible. To overcome this, suit products made with knit materials that consider lightness to improve fit, elasticity, and activity were released. Product competitiveness has been secured in the market, and product development continues to this day.

However, although the knitted suit has excellent activity and lightness, it does not have a luxurious appearance (glossy) and soft touch, so there is a limit to being applied as an expensive brand product, and most of it is applied as a mass product.

In order to overcome these shortcomings, high-sensitivity velvet materials have been developed considering a warm touch and a luxurious appearance (glossy), and high-quality suit products are being developed.

Velvets currently on the market are divided into tricot velvet and woven velvet, and woven velvet material is mainly applied to high-quality suits.

In the case of the existing tricot velvet, when the weight is lowered, problems occur due to span, and production at least 380 g/yd or more. It is mainly applied to home interior products or mid- to low-priced clothing products, rather than high-priced clothing products because of its poor recovery properties.

On the other hand, in the case of woven velvet material, it is mainly applied as a high-priced suit material, but there is a door jam that has a very high selling price due to the high production cost. there is
