Abstract

A fabrics for producing jeans, in particular, a knitted fabric for producing indigo-dyed cotton denim jeans, which is suitable for producing four-season type jeans, is provided. Here, raw yarn obtained by dyeing 100% cotton yarn with natural indigo dyestuffs is knitted by a ring-type knitting machine, to thus provide a knitted fabric for producing four-season type indigo-dyed cotton denim jeans which possesses color tones such as blue and black peculiar to jeans as well as possesses functions such as flexibility, ventilation, warmth-keeping performance, and elasticity, and which can be also put on in midsummer and midwinter. Cotton denim jeans are not knitted by a cotton knitting machine which discriminates warp and weft to thus cause skin friction and creases, but are knitted with the knitted fabric by a ring-type knitting machine without discrimination of warp and weft. Accordingly, the knitted fabric possesses functions of flexibility, ventilation, warmth-keeping performance, and elasticity, according to textual features of the knitted fabrics. Also, raw yarn before knitting is colored with blue or black which is a natural indigo dye, to thereby possess a color peculiar to the jeans and impose no burden of friction with the skin on a wearer. Also, although the four-season type indigo-dyed cotton denim jeans closely contact any portion of the wearer's body, they can be put on even in midsummer and midwinter due to a soft feeling to the touch. To realize this, a knitted fabric for producing cotton denim jeans is produced by the steps of: obtaining raw yarn by dyeing 100% cotton yarn with natural indigo dyestuffs of blue or black; directly inserting rubber yarn which has spandex features into the raw yarn; and simultaneously knitting the rubber-yarn inserted raw yarn by a ring-type knitting machine, to thus provide the knitted fabric for producing indigo-dyed cotton denim jeans which possesses spandex features.

Description

Indigo-blue textile COARSE DRILL cowboy's knit fabric

Technical field

The invention relates to jeans (Jeans) weaving face fabric---promptly be fit to the invention of indigo-blue textile COARSE DRILL cowboy's knit fabric of dress throughout the year.

Background technology

Existing conventional jeans weaving face fabric mainly adopts is the textile COARSE DRILL cloth linings such as (denim) that utilizes the raw yarn weaving of distinguishing warp thread and weft yarn to form.

These linings are utilized indigo look (indigo) dye coloring, and the lining that obtains after the weaving not only texture is of poor quality, soft inadequately, and be easy to produce fold.

In addition, this class jean is not suitable in the summer of sweltering heat or cold dress in winter.Because comfortableness and absorption of perspiration when not possessing with skin friction when wearing summer, can only keep fastness, but lack gas permeability, make the wearer feel sultry often; And, but lack heat insulating ability in the winter of cold.And, no matter be in summer or winter, because the sense of touch of contact skin is coarse stiff, be easy to cause the stimulation or the allergic reaction of skin.

In addition, also exist the difficult and dry difficult problem of washing.

Summary of the invention

The objective of the invention is in order to address the above problem, develop the new material that leads brand-new popular prevailing custom, it not only possesses functional characteristics such as flexibility, gas permeability, heat insulating ability and elasticity, is also keeping the distinctive color of cowboy (blue, black), is fit to each dress in season of spring, summer, autumn and winter.

The indigo-blue textile COARSE DRILL cowboy's knit fabric of the present invention: in the process that obtains lining, do not adopt and distinguish warp thread and weft yarn, cause skin friction and go out the cotton knitting machine of pleat easily easily, but adopt the round latitude machine of not distinguishing warp thread and weft yarn to weave, thereby keep the distinctive flexibility of knit fabric, gas permeability, heat insulating ability and elasticity; Simultaneously, utilizing natural indigo dye---blueness or black dyes carry out painted to the raw yarn before weaving, keep the distinctive color of denim, even if can not make skin feel any discomfort with skin friction yet, when closely contacting, give soft comfort with human body, even if summer and cold winter in sweltering heat can wear, and be suitable for four seasons.

Purpose of the present invention realizes like this: using natural indigo look dyestuff (blueness or black) 100% cotton yarn to be carried out inweave rubber-like rubber yarn in the raw yarn that painted back obtains, utilize circle latitude machine to weave, to obtain to have more elastomeric indigo look COARSE DRILL cowboy knit fabric.

The specific embodiment

Explain most preferred embodiment of the present invention below in conjunction with the correlation test data

The subordinate list test list of results that to be Korea S raw yarn cloth testing research institute compare the various performances of the cotton knitted fabric (#1) of the development according to the present invention and conventional textile COARSE DRILL jean (#2).

The cotton knitted fabric (#1) of development carries out painted to 100% cotton yarn or contaminates obtaining raw yarn by utilizing natural indigo look dyestuff (blueness or black) according to the present invention, in raw yarn, inweave rubber sand with elastic component, warp thread do not distinguished by employing circle latitude machine and weft yarn ground weaves, and makes lining obtain functional characteristics such as the distinctive flexibility of knit fabric, gas permeability, heat insulating ability, elasticity.

Make jeans or other jeans if utilize above-mentioned pure cotton knitting face fabric (#1), can not only make clothes keep the distinctive color of denim, and suitable four seasons spring, summer, autumn and winter wear arbitrarily, be convenient to washing and dry, because interior outside texture softness, dress feels more comfortable.The gas permeability of this lining, heat insulating ability and elastic energy guarantee the docile wearing feeling of nature, can not cause disease of skin, particularly owing to all have retractility on all directions all around, after being made into clothes, which closely contact with position of health, can both keep very high fastness, and prevent wrinkling.

If with reference to Korea S raw yarn cloth testing research institute this knit fabric (#1) and conventional textile COARSE DRILL jean (#2) are compared the test list of results that the back obtains, just can see the remarkable function of the knit fabric (#1) of development effectively according to the present invention.Specifically relatively the contents are as follows:
