Description

Preparation method of seersucker
Technical Field
The invention belongs to the technical field of textile yarns, and relates to a preparation method of seersucker.
Background
The seersucker is a traditional textile with unique texture, appearance and good wearability. There are two groups of seersucker fabric structures: ground weave fabrics and bubble weave fabrics. The bubble fabrics are wavy, so that certain space is reserved among the fabrics. When the fabric is worn, the fabric cannot be tightly attached to the skin, so that the air flow is facilitated, and the ventilation and perspiration are realized. Therefore, the seersucker has been widely used for summer clothing. Due to its unique aesthetic appearance, seersucker has been used in recent years in a large number of sports and leisure apparel, as well as in household textiles.
Generally, the foam warp yarns are thicker than the ground warp yarns, so that the cloth at the foam warp positions is tighter; the warp feeding amount of the warp is large, so that an obvious bubble effect can be achieved, and the tension of the warp is small, so that the cloth cover is wavy, and the two factors are combined to further make the cloth more plump. And the thick warp of bubble makes the surface fabric of bubble department thicker, is favorable to standing upright and protruding of bubble. However, the thick bubbles make the fabric thick and lose the refreshing feeling of thin and thin fabric. The fullness of the seersucker is directly related to the thickness, firmness and smoothness of the cloth at the seersucker, the density of warp and weft is high, and the seersucker stands upright.
Therefore, it is very important to research a method for improving the fullness (bubble stiffness) of the seersucker on the basis of keeping the fabric fresh and cool.
Disclosure of Invention
The invention provides a preparation method of seersucker; the purpose is to solve the problem that the refreshing feeling of the seersucker is reduced when the hand feeling fullness is improved in the prior art.
In order to achieve the purpose, the invention adopts the following scheme:
a preparation method of seersucker comprises the steps of knitting and weaving 8.3tex terylene low stretch yarn and 14.5tex combed cotton yarn to obtain seersucker;
the knitting needles are arranged as follows: 8 needles are a cycle, and the 3-needle track single-face circular knitting machine is arranged according to the sequence of AAABAAAC;
the upper triangular process diagram is as follows: 51F is a cycle, and the equipment has 102F in total; no. A needles and No. B needles of 1F to 12F and 25F to 36F are looped, and No. C needles float; the No. A needles and the No. C needles of the 12F-24F are looped, and the No. B needles float; all the knitting needles of 37F to 41F and 47F to 51F are completely looped; no. A needles of the 42F-46F are looped, and No. B needles and No. C needles float;
the threading mode is as follows: the 1F, 13F, 25F and 42F penetrate the terylene low stretch yarn, and the rest penetrate the combed cotton yarn;
the preparation process of the polyester low stretch yarn comprises the following steps:
in the process of preparing fibers from PET according to an FDY process, cooling by circular blowing, controlling arrangement of spinneret orifices on a spinneret plate to meet a certain condition, and performing relaxation heat treatment after FDY yarns are prepared to obtain the polyester low-stretch yarns;
the spinneret orifices are crescent spinneret orifices and H-shaped spinneret orifices, the cross section of each crescent spinneret orifice is surrounded by an outer arc line M and an inner arc line N, two intersection points of the outer arc line M and the inner arc line N are A and B respectively, and the length of a line segment AB is not more than 0.1 mm;
the certain conditions are as follows: all spinneret orifices are distributed in a concentric circle, the crescent spinneret orifices are located on the circle of the outermost circle, the straight line where the two points AB on the cross section of any crescent spinneret orifice are located is used as a datum line, the straight lines where the two points AB on the cross sections of all other crescent spinneret orifices are located are at a certain included angle with the datum line, and the included angles are randomly distributed within the range of 0-360 degrees.
The principle of the invention is as follows:
after the melt is extruded from the crescent-shaped spinneret orifices, the cooling speeds of different positions are inconsistent, the part which is cooled quickly is not easy to be drawn and thinned in the subsequent process, the stress is not concentrated, the part which is cooled slowly is easy to be drawn and thinned in the subsequent process, and the stress and the thickness are concentrated, so the stress and the thickness on the cross section of the fiber are not symmetrical, the fiber with the asymmetrical stress and the thickness on the cross section can present three-dimensional curling performance in the heat treatment or the stretching process, the curling is good, the elastic recovery rate of the fiber is high, and the stress and the thickness on the cross section can generate larger influence on the three-dimensional curling shape of the fiber at the same time, the invention controls the arrangement of the crescent-shaped spinneret orifices to meet certain conditions, so that the conditions of the stress and the thickness on the cross section of the fiber extruded from different crescent-shaped spinneret orifices are not completely same, and further the curling conditions of the fiber extruded from, the single filaments have not the same curling direction, and the single filaments with inconsistent curling direction can generate disorder in a bundle of filaments, so that the bundle of filaments has bulkier and fuller hand feeling. In addition, the fluffiness of the H-shaped fiber is better, the H-shaped fiber is matched with crescent-shaped fiber with the same monofilament direction, the fluffiness and the fullness can be further improved, the polyester low stretch yarn is used for weaving the seersucker, the raw materials of the seersucker are lighter under the condition of the same fluffiness and the fullness, the style of the seersucker is obvious and light, the curling form is caused by the difference of the thermal shrinkage rates of two parts with asymmetric stress, the curling is stable, and the stress is difficult to eliminate under the normal washing and using conditions, namely the curling state is not greatly influenced, so the style is stable and durable.
