Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a knitted fabric,

The present invention relates to a woven and knitted linen knitted fabric which is excellent in stretchability and dyeability and can be hand-washed, and a method for producing the same.

[0002] Recently, as the demands and demands of users for textile products have diversified, various characteristics have been developed in the fields of underwear sports wear, protective clothing, industrial materials, for example, stretchable circular knitted fabric with high strength, soft stretchability, There is a growing demand for various methods for manufacturing the same.

In order to produce ordinary circular knitted fabric, for example, a method of using polyurethane-based fibers having excellent stretchability, a method of knitting a circular knitted fabric using the polyurethane fiber and nylon fiber in combination, or a method of using a composite yarn of polyurethane and nylon And the like are known. However, in the case of the former, there is a problem that the tactile feel is stiff due to the intrinsic properties of the polyurethane, the quality of the fabric is not good, and in particular, the drape property is deteriorated. In the latter case, It is not easy to handle during dyeing.

In addition, the competitiveness of the domestic textile fashion industry is losing competitiveness to the developing countries such as China, as in the case of general knit products, while the domestic and overseas market share of functional fabrics, fashion apparel and industrial textile products is continuously expanding. In this situation, knitwear is suitable for consumer 's emotional demand in fashion apparel, and in developed countries such as Europe, there is active development of machinery and products, but Korea is still below this level. In addition, as the global warming phenomenon accelerates and the oil price era continues, when the concept of indoor heating is shifting, home textiles and clothing used indoors are also lighter than existing heavy and thick products, and have high functionality Or multi-functional products tend to be increasingly preferred.

The development and demand for a new material knitted garment incorporating a linen under the textile industry atmosphere is increasing. For example, it is possible to produce a knit garment having a soft feel due to its excellent drape characteristic, Modified rayon yarn, which has a twist coefficient (twist coefficient per unit length d1 / 2) of 6.5 to 7.5 and which has been swollen with a swelling agent, is used in the yarn constituting the modified rayon fabric to produce a linen-like fabric, The rayon yarn is woven by using one of the warp and weft yarns, and then the woven rayon fabric is swelled with a swelling agent which is an aqueous alkaline solution having an alkali agent concentration of 10 to 20% to produce a linen-like fabric. However, when the content of the rayon yarn is less than 50% by weight in the conventional production method as described above, there is a problem that the feeling of cool feeling unique to the woven fabric is insufficient. If the number of links is less than 6.5, it is difficult to express a cool feeling unique to the fabric. If the number of links exceeds 7.5, the shrinkage rate of the fabric becomes too high and commercialization becomes difficult. Specifically, Korean Patent Laid-Open Publication No. 2010-0098911 relates to a linen-like modified rayon fabric and a method for producing the same, wherein the yarn constituting the fabric is composed of modified rayon having swell numbers of 6.5 to 7.5 and swelling treated with a swelling agent, Linen-like modified rayon fabrics characterized by the inclusion of yarns ". Korean Patent Laid-Open Publication No. 2010-0103182 discloses a linen fabric woven in plain weave by warp and weft, wherein the warp comprises a plurality of first warp yarns having a thickness of 40 lea and a plurality of second warp yarns having a thickness of 60 lea Wherein the plurality of first warp yarns and the plurality of second warp yarns are mixed and mixed at a ratio of 1: 1, wherein the weft yarn comprises a plurality of first weft yarns having a thickness of 40 lea and a plurality of second weft yarns having a thickness of 60 lea Wherein the plurality of first weft yarns and the plurality of second weft yarns are mixed and arranged in a 1: 1 ratio. However, since the methods disclosed in the above documents are complicated in manufacturing process or are related to an improvement method using existing linen fabrics, there is a problem that a manufacturing cost is increased and a difficulty is encountered in mass production.

Korean Patent Publication No. 2006-0072400 (Published on Jun. 28, 2006) Korean Published Patent Application No. 2006-0017622 (Publication date: Feb. 24, 2006) Korea Patent Publication No. 2012-0041638 (Publication date: May 2, 2012)

The results of measuring the physical properties of the knitted linen knitted fabric of Tables 4 to 5 indicate that the knitted linen knitted fabric produced in Examples 1 to 5 has a low elongation percentage and a low washing dimensional change rate It was confirmed that the washing fastness was excellent.

However, in Comparative Example 1 prepared from linen yarn of 52 lea exceeding 48 lea, the elongation percentage and elongation recovery rate of the linen knitted fabric were inferior in stretchability as compared with Example 1. In the case of Comparative Example 2, the physical properties of the cyclic elongation percentage and the elongation recovery rate are good, but the amount of the linen in the knitted fabric is insufficient, resulting in a problem of poor commercial quality.

Also, in Comparative Example 3, which was manufactured using a DTY composite yarn of 240 denier having a total fineness exceeding 200 denier, there was a problem that the elongation was somewhat low as compared with Example 1, and a total denier of 150 denier In the case of Comparative Example 4 produced using the DTY composite yarn, there was a problem that the rate of change of the washing dimension was increased.

In the case of Comparative Example 5 having a loop length ratio of 1: 1.24 in which the loop length ratio of the linen yarn and the DTY composite yarn exceeds 1: 1.2, the properties such as elongation and washing fastness are excellent, There was a problem.

Further, in the case of Comparative Example 6 in which the second tenting was performed at 160 占 폚 in which the second tenting was less than 170 占 폚 during the production of the knitted fabric of the knitted fabric, the elongation was lowered and the washing fastness was lowered to the third level In the case of Comparative Example 7 in which the second tenting was performed at 195 占 폚 in which the secondary tentering exceeded 180 占 폚 in the second tenting, the elongation recovery rate in the course direction was lower than that in Example 1, There has been a problem that the rate of change of the washing dimension is increased.

It can be seen from the above Examples and Experimental Examples that the woven linen knitted fabric manufactured using the method and materials of the present invention has high elasticity and is excellent in washing fastness and can be hand-washed.
