[0040] The following are specific embodiments
[0041] Example 1
[0042] Referring again to FIG. 1 , in this embodiment, the warp yarn is a blended yarn obtained by twisting cotton fiber and lyocell fiber, and the warp yarn is an undyed white yarn. Among them, the mass ratio of cotton fiber to lyocell fiber is 8:2, and the total number of warp yarns is 4900. The yarn count specification of the warp yarn is 12 British count. The weft yarn 20 is core-spun yarn, wherein the yarn core is a spandex yarn with a pre-draft multiple of 3.5 times, and the outer layer is polyester fiber and viscose. The mass ratio of polyester, viscose and spandex yarn is 67:29:4, and the yarn count specification of the weft yarn 20 is 21 British count. The warp density of the environmentally friendly denim fabric is 68 strands / inch, and the weft density of the environmentally friendly denim fabric is 52 strands / inch. The standard finishing items are singeing, cold stacking, steam washing, semi-bleaching, tentering and shrinkage prevention.
[0043] Example 2
[0044] Referring again to Figure 2, in this embodiment, the warp yarn uses two different yarns, and both yarns are undyed white yarns. The first yarn 10 is a blended yarn obtained by twisting cotton fiber and lyocell fiber, and the mass ratio of cotton fiber to lyocell fiber is 8:2. The second yarn 30 is a polyester spandex core-spun yarn, with spandex as the yarn core and polyester as the outer layer, and the mass ratio of polyester to spandex is 85:15. The yarn count specification of the warp yarn is 60 British counts, the root number ratio of the first yarn 10 and the second yarn 30 is 1:1, the first yarn 10 and the second yarn 30 are alternately spaced, and the total number of warp yarns is 8080. The weft yarn 20 uses a blended yarn obtained by twisting cotton fiber and lyocell fiber, and the yarn count specification of the weft yarn 20 is 12 British counts. The warp density of the environmentally friendly denim fabric is 95 roots / inch, and the weft density of the environmentally friendly denim fabric is 40 roots / inch. Standard finishing items include singeing, cold stacking, steam washing, semi-bleaching, stentering and shrink proofing.
[0045] Comparative Example 1
[0046] The denim fabric in Comparative Example 1 is woven with the same warp and weft yarns as those in Example 1, but the warp yarn in Comparative Example 1 is yarn dyed with indigo dye. The post-finishing process is singeing, desizing, softening, shrinking, and finished product.
[0047] Comparative Example 2
[0048] The denim fabric in Comparative Example 2 is woven with the same warp and weft yarns as those in Example 2, but the warp yarn in Comparative Example 2 is yarn dyed with indigo dye. The post-finishing process is singeing, desizing, skewing, shrink-proofing, and finished product.
[0049] The denim fabrics in Comparative Examples 1 and 2 were washed to obtain a washing effect, and the environmentally friendly denim fabrics in Examples 1 and 2 were dyed, so that the environmentally friendly denim fabric in Example 1 obtained a dyeing depth and a washing effect similar to those of the fabric in Comparative Example 1, and the environmentally friendly denim fabric in Example 2 obtained a dyeing depth and a washing effect similar to those of the fabric in Comparative Example 2. The fabrics after the above processing were tested, and the test standards were as follows: rubbing fastness: GB / T3920, soap fastness: GB / T3921 method C (3), tear strength: GB / T3917.1, breaking strength: GB / T3923.2, and the test results are shown in Table 1 below:
[0050] Table 1
[0051]
[0052] As can be seen from the above table, the fabric of Example 1 has better friction fastness and soap fastness than the fabric in Comparative Example 1 when achieving similar dyeing and washing effects, and can also maintain strength better than the fabric in Comparative Example 1. The friction fastness, soap fastness, tear strength and breaking strength of the fabric of Example 2 are all better than those of Comparative Example 2. Since the first cellulose fiber and the second cellulose fiber have different color absorption rates and shrinkage rates, the above-mentioned environmentally friendly denim fabric can shrink in small areas to different degrees in different parts through dyeing, so that the fabric presents an effect similar to that of denim washing. At the same time, the above-mentioned environmentally friendly denim fabric can maintain high strength and fastness while achieving the washing effect through the yarn selection of the warp yarn and the weft yarn 20 and the coordination of the organizational structure.
[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims, and the description and drawings may be used to interpret the contents of the claims.
