Detailed Description
In order that the invention may be more fully understood, a more particular description of the invention will now be rendered by reference to specific embodiments thereof that are illustrated in the appended drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Although currently, depending on the different finishing methods, the types of fabrics and the weave structures of the woven fabrics of the received fabric, there are corresponding yarn strength standards for the yarns, which are used to ensure the strength properties of the woven fabrics. However, the yarn strength standard is a general standard, which is not distinguished according to different yarns, and only gives the yarn strength standards of the warp or weft yarns required for the determined woven fabric, such as finishing method, cloth type, and weave structure, in general, that is, the corresponding warp standard yarn strength and weft standard yarn strength. For example, in the case of weaving a woven fabric such as a plaid, the yarn strength criterion does not take into account how many yarns of a particular color in the warp or weft of the woven fabric should be used, particularly some less used and more expensive yarns, but rather, all the yarns are cut to the above-mentioned general yarn strength criterion. However, the yarn strength also determines the cost of raw materials, and the same yarn strength is generally the same when the yarns are woven in the same color; the yarn strength of the yarns of different colors may be the same or different. The inventors therefore propose that for some yarns in smaller amounts, it is possible to consider color discrimination and to adjust the individual yarn strengths on the basis of the original yarn strength criteria, provided that the woven fabric produced meets the usual strength criteria for woven fabrics.
Based on this, the invention provides an embodiment of the yarn selecting method for weaving the woven fabric, which comprises the following steps S1-S4.
Step S1: the warp yarns and/or the weft yarns required for weaving the woven fabric are classified according to colors, and the yarn consumption ratio of the yarns of each color in the warp yarns and/or the weft yarns is obtained.
It can be understood that the warp yarns or the weft yarns required for weaving the woven fabric can be classified according to colors, and the yarn strength of each color in the warp yarns or the weft yarns can be adjusted independently; the warp and weft yarns required for weaving the woven fabric can be classified according to the colors at the same time, and the yarn strength of each color in the warp and weft yarns can be adjusted at the same time.
The yarn quantity ratio of the yarns of each color in the warp yarn is a ratio of the number of the yarns of each color in the warp direction to the number of all the yarns in the warp direction, and the yarn quantity ratio of the yarns of each color in the weft yarn is a ratio of the number of the yarns of each color in the weft direction to the number of all the yarns in the weft direction. For example, the yarns in the warp direction, i.e., the warp yarns, are of two different colors, wherein the yarn usage ratio of one color of yarn is 10% and the yarn usage ratio of the other color of yarn in the warp direction is 90%.
Step S2: when the yarn usage ratio of the yarn of a single color in the warp and/or the weft is not more than 50%, the yarn emphasis adjustment coefficient of the yarn of the corresponding color in the corresponding yarn (i.e. in the warp and/or the weft) is obtained according to the yarn usage ratio of the yarn of the color in the warp and/or the weft.
It can be understood that, for example, when only the warp yarns required for weaving the woven fabric are classified by color alone, and the yarn usage ratio of the yarns of each color in the warp yarns is obtained, the yarn usage ratio of the yarns of the individual color in the warp yarns does not exceed 50%; that is, the obtained yarn consumption ratio is not more than 50%, that is, the warp yarns with strong yarns need to be adjusted to have more than two colors and the yarn consumption ratio of the single color yarn is not more than 50%. In this case, if the weft yarn does not need to be adjusted in yarn strength, the weft yarn may be a yarn of one color or may be a yarn of two or more colors.
Specifically, according to the yarn using amount ratio of the yarns of each color in the warp yarns, the yarn emphasis adjustment coefficient of the yarn of the corresponding color in the warp yarns is obtained; and acquiring the yarn emphasis adjustment coefficient of the yarn of the corresponding color in the weft yarn according to the yarn consumption ratio of the yarn of each color in the weft yarn.
In one embodiment, the yarn amount ratio of each color of the yarn, whether it is the warp or the weft, is equal to the yarn weight adjustment coefficient of the corresponding color, as follows.
The yarn quantity ratio of the yarn of any color in the warp and/or the weft is set as Y, and the yarn strength integral coefficient of the yarn of the corresponding color in the warp and/or the weft is set as delta;
the step S2 is to obtain the yarn emphasis adjustment coefficient δ of the yarn of the corresponding color in the warp and/or the weft according to the yarn usage ratio Y of the yarn of each color in the warp and/or the weft as follows:
when Y is more than 0 and less than or equal to 10 percent, delta is more than or equal to 0.1 and less than or equal to 0.2;
when Y is more than 10% and less than or equal to 20%, delta is more than 0.2 and less than or equal to 0.4;
when Y is more than 20% and less than or equal to 30%, delta is more than 0.4 and less than or equal to 0.6;
when Y is more than 30% and less than or equal to 40%, delta is more than 0.6 and less than or equal to 0.8;
when Y is more than 40% and less than or equal to 50%, delta is more than 0.8 and less than or equal to 1.0.
And when 50% < Y < 100%, 1/δ is 0. That is, the yarn selecting method of the present invention actually adjusts only the yarn consumption ratio of the yarns of each color in the warp and/or weft to satisfy 0< Y ≦ 50%, and when 50% < Y ≦ 100%, 1/δ ≦ 0 indicates that the adjustment width is 0.
Step S3: when the yarn consumption ratio of only one color of yarn in the corresponding yarns is not more than 50%, determining the yarn consumption strength of the yarn of the color in the corresponding yarns according to the yarn strength finishing coefficient of the yarn of the color in the corresponding yarns and the strength of the warp standard yarn and/or the strength of the weft standard yarn of the woven fabric, and not adjusting the yarns of other colors; when the yarn using amount ratio of yarns with various colors in the corresponding yarns is not more than 50%, determining the yarns to be adjusted in the yarns with various colors, wherein the yarns to be adjusted are yarns with one color or yarns with various colors, controlling the total yarn using amount ratio of the yarns to be adjusted in the corresponding yarns to be not more than 50%, determining the yarn using strength of the yarns with various colors in the corresponding yarns to be adjusted according to the yarn strength adjustment coefficient of the yarns with various colors in the corresponding yarns to be adjusted and the warp standard yarn strength and/or the weft standard yarn strength of the woven fabric, and not adjusting other yarns except the yarns to be adjusted.
It can be understood that when the yarn usage ratio of only one color of the corresponding yarns is not more than 50%, the yarn usage ratio of the yarns not more than 50% may be adjusted to be strong. When the yarn consumption ratio of the yarns with two or more colors in the corresponding yarns is not more than 50%, only one of the yarns with the yarn consumption ratio not more than 50% can be regulated to be strong, and the yarns with the two or more colors with the yarn consumption ratio not more than 50% can also be simultaneously regulated to be strong, so that the total yarn consumption ratio of all the yarns to be regulated in the corresponding yarns is not more than 50% to avoid greatly influencing the quality of the woven fabric and causing the quality to be unqualified.
Specifically, the yarn strength of the yarn with good color in the warp is determined according to the yarn strength finishing coefficient of the yarn with the color in the warp and the standard yarn strength of the warp of the woven fabric; and/or determining the yarn strength of the yarn of the color in the weft yarn according to the yarn strength finishing factor of the yarn of the color in the weft yarn and the standard yarn strength of the weft yarn of the woven fabric.
The warp standard yarn strength and/or the weft standard yarn strength of the woven fabric can be set to be F1(ii) a Step S3 is performed according to each color in the warp and/or weftThe yarn strength of the yarn (D) is the finishing factor delta and the warp yarn strength and/or the weft yarn strength of the woven fabric (F)1) The yarn strength of each color of the determined warp and/or weft is set to F2(ii) a Then there is F2＝F1-(Q/δ)。
It will be appreciated that both the warp and weft yarns adopt the formula F2＝F1- (Q/δ) are adjusted, however, in actual production, the values of the warp standard yarn strength and the weft standard yarn strength of the woven fabric may not be equal.
Wherein, F1And F2The unit of (A) is cN, Q is the basic adjustable yarn strength, 0<Q is less than or equal to 10 cN. Understandably, according to the summary of experience, the smaller the yarn quantity ratio of the color in the corresponding yarn is, the larger the corresponding Q value is; conversely, the larger the yarn quantity ratio corresponding to the color in the yarn, the smaller the value of Q.
Further, the value of Q is preferably: q is more than or equal to 1cN and less than or equal to 9 cN.
As can be seen from the step of specifically obtaining the yarn strength adjustment coefficient δ of the yarn of the corresponding color in the warp and/or weft in combination with the step S2, when the base adjustable yarn strength Q is a constant value and 0< Y ≦ 50%, the smaller the yarn usage amount of the yarn of each color in the warp and/or weft is than Y, the larger the adjustment width of the yarn strength of the corresponding color is; the larger the yarn usage ratio Y of the yarns of each color in the warp and/or weft, the smaller the adjustment width of the yarn usage strength corresponding to that color. When 50% < Y < 100%, the width of the adjustment of the yarn strength corresponding to the color is 0.
Step S4: the yarns of the respective colors in the warp and/or weft are selected according to the determined yarn strength.
The invention further provides a woven fabric weaving method, which adopts the woven fabric weaving yarn selection method to select yarns of various colors in the warp yarns and/or the weft yarns for woven weaving.
The shuttle-woven fabric weaving yarn selection method classifies the warp yarns and/or the weft yarns according to colors, and determines the yarn emphasis integer coefficient according to the yarn quantity ratio corresponding to the yarns of each color in the warp yarns and/or the weft yarns; and then determining the yarn strength of each color yarn in the warp and/or weft according to the warp standard yarn strength and/or the weft standard yarn strength of the woven fabric. The yarns selected by the method are woven according to the original weaving method, the prepared woven fabric can meet the general strength standard of the woven fabric, and the yarn using strength can be properly reduced compared with the yarn using strength standard, so that the yarn using cost can be properly reduced, and the quality and the yarn using cost of the woven fabric can be simultaneously controlled.
The following are specific examples.
Comparative example 1
And (3) processing the yarns according to the processes of dyeing, warping, sizing, tatting weaving and after-finishing to obtain the tatted fabric. Wherein, the post-finishing process comprises singeing, desizing, mercerizing, liquid ammonia, tide crosslinking and shaping, tide crosslinking and storage, water washing and shaping.
The woven fabric is a plain weave lattice fabric with a warp and weft density of 120 x 80 and a yarn count of 40S x 80S/2. Wherein, the warp direction of the grid cloth is provided with two yarns X1 and X2 with different colors, and the weft direction yarn is also provided with the two yarns X1 and X2; in both the warp and weft, the yarn usage ratio of X1 was 10%, and the yarn usage ratio of X2 was 90%. The strength of the warp standard yarns is 340cN, and the strength of the weft standard yarns is 380 cN.
Example 1
Example 1 is substantially the same as comparative example 1 except that it is according to formula F above2＝F1Adjusting the yarn strength (Q/delta), and calculating the required yarn strength after adjusting the yarns X1 and X2 with different colors in the warp direction and the weft direction.
Wherein, the Q value of the yarn strength formula is 1 cN.
Warp direction: f1340 cN; in the warp, the yarn consumption ratio of X1 is 10%, and the yarn consumption ratio of X2 is 90%; therefore, in the warp yarn, the yarn emphasis adjustment coefficient δ of X1 may be 0.1, and the yarn emphasis adjustment coefficient δ of X1 may be 1/δ equal to 0. Thus, the yarn strengths for warp directions X1 and X2 were determined to be 330cN and 340cN, respectively.
In a similar manner, in the weft direction: f1380 cN; in the weft yarns, the yarn consumption ratio of X1 is 10 percent, and the yarn consumption ratio of X2 is 90 percent; therefore, in the weft, the yarn weight adjustment factor δ of X1 may be 0.1, and the yarn weight adjustment factor δ of X1 may be 1And/delta is 0. Thus, the fill directions X1 and X2 were determined to be 370cN and 380cN, respectively.
Example 2
Example 2 differs from example 1 in that the value of Q for the yarn strength formula is 9cN and the yarn strength adjustment factor δ for X1 in the warp and weft yarns is 0.2. Thus:
warp direction: f1340 cN; in the warp, the yarn consumption ratio of X1 is 10%, and the yarn consumption ratio of X2 is 90%; therefore, in the warp yarn, the yarn emphasis adjustment coefficient δ of X1 is 0.2, and the yarn emphasis adjustment coefficient δ of X1 is 1/δ equal to 0. Thus, the yarn strengths for the warp directions X1 and X2 were determined to be 295cN and 340cN, respectively.
In a similar manner, in the weft direction: f1380 cN; in the weft yarns, the yarn consumption ratio of X1 is 10 percent, and the yarn consumption ratio of X2 is 90 percent; therefore, in the weft, the yarn emphasis adjustment coefficient δ of X1 is 0.2, and the yarn emphasis adjustment coefficient δ of X1 is 1/δ equal to 0. Thus, the fill directions X1 and X2 were determined to be 335cN and 380cN, respectively.
The physical properties of the fabrics produced in the woven fabrics of comparative example 1, example 1 and example 2 were measured by a physical testing facility, and the results are shown in table 1. The fabric strength standard is a qualified strength standard of the woven fabric and is considered from the warp tearing strength and the weft tearing strength respectively.
