Here, the present invention defines a non-hem collar, and determines a specific test method and relevant standards for judging a non-hem collar.

Definition of non-rolled collar: Any collar that can meet the standard determined in the following table 1 after passing the test and washing can be called non-rolled collar.

Table 1

The test methods and judgment standards provided in Table 1 are described in detail below:

The present invention carries out the following three tests/washing items for the collar to be tested. If the collar after being processed by the three testing/washing items can reach the judgment criteria as described in Table 1 above, the collar is not rolled side collar.

Elasticity recovery (as is/washed 5 times)

The premise that the collar to be tested can achieve the effect of non-hemming is that in addition to the excellent stretch elasticity of the collar, the more important thing is that it can have sufficient elastic recovery, so that in the process of repeated use, it undergoes stretching, After washing, it can still return to its original state as much as possible. Therefore, in the item of elastic recovery (as it is/washed 5 times), the present invention mainly examines the elastic recovery performance of the collar to be tested in the weft direction. The test process adopts the ASTM D2594 international standard method. The test process includes: stretching the collar to be tested in the weft direction. 30%, placed for 2 hours, and the recovery time after removing the outer surface was 60 seconds and 1 hour, respectively. According to the test results, the present invention sets the elastic recovery standards as: <6% (60s) and <4% (1h).

Wrinkle recovery corner (as is/washed 5 times)

To a certain extent, the collar deforms because it cannot fully return to its original state due to external pressure, resulting in deformation.

The invention uses the wrinkle recovery angle to measure the recovery performance of the collar after pile pressing and wrinkling, and the wrinkle recovery angle is measured by the method in AATCC66-2006.

Through preliminary comparative tests, the applicant found that a collar with a larger wrinkle recovery angle has a correspondingly better shape-retaining performance. When the wrinkle recovery angle is >135°, the collar has better shape-retaining performance. The standard of recovery angle is set as: >135°.

Appearance sewing sample (as is/washed 10 times)

In the method of verifying whether the collar is washable and not curled, the most important and intuitive method is to judge whether it is washable and not curled by observing the real object. In this regard, it is necessary to use designated fabrics and collars (high-elasticity, high-conformity and washable flat knitting collars provided by the present invention), make Mock-Up (ready-to-wear model), and then perform the required times (such as 10 times) of Mock-Up. Wash, and then compare the Mock-Up after the required number of home washing with the standard sample. After comparison, if it is found that the Mock-Up can follow the standard sample, the Mock-Up can be defined as a non-rolled collar.

Wherein, the standard sample is a sample that has good flatness, no deformation, and no curling after 10 household washings. Those skilled in the art can reasonably select the standard sample according to the actual operation requirements on site; In the specific embodiment of the present invention, if the used garment model after 10 home washings still has good flatness, and is not deformed or curled, the garment model after 10 home washings can be used as a standard sample.

The high-elasticity and high-shape-retaining washable flat knitting collar provided by the present invention is a high-elasticity flat-knitting collar, which has the characteristics of no curling and no deformation after multiple washings. The collar has good elastic recovery, wrinkle recovery, excellent shape retention after washing, and can achieve the performance of no curling after multiple (10) washings. The high-elasticity, high-shape-retaining, and washing-resistant flat knitting collar provided by the present invention is mainly used as the collar of high-end POLO T-shirts, which can solve the problem that the collars of POLO T-shirts that have troubled customers and consumers for a long time have wavy, lotus leaves after washing.

The high-elasticity polyester yarn is 75D/36F high-elasticity, no mesh, DTY polyester yarn; the range of the elongation at break of the polyester yarn is 21±5%. The above 100% long-staple cotton yarn and high-stretch polyester yarn should be dyed before weaving, and the color of the dyed yarn is consistent with the color of the final finished fabric.

Model used: Shima Seiki H313 three-system flat knitting machine, the stitch length is 16G, and the coil length is 25C (120-125mm).

Use 60S/2X2 (X2 represents two long-staple cotton yarns) compact spun cotton yarn and 75D/36F X2 (X2 represents two high-strength polyester yarns) denier polyester yarns as the raw material yarns for the fabric surface and the fabric bottom , the yarns are fed together through different yarn nozzles to participate in weaving.

Weaving according to the weaving method shown in Figure 1, namely:

1) Use 2 high-elastic polyester yarns and 2 100% long-staple cotton yarns as front yarns, and perform single-sided knitting on the needle bed on the flat knitting machine to form the front;

2) Two high-elastic polyester yarns and two 100% long-staple cotton yarns are used as reverse yarns, and single-sided knitting is performed on the needle bed under the flat knitting machine to form the reverse surface;

3) Using a stretch spandex yarn as a connecting thread, double-sided knitting is performed on the upper and lower needle beds of the flat knitting machine, and the front and back sides are connected;

Repeat weaving according to the above-mentioned weaving method in step 1)-step 3) to obtain a double-sided flat knitting collar.

At the same time, when the flat knitting collar is used, it is necessary to check whether the high-stretch polyester yarn of the boot cloth is exposed to the bottom, to ensure that it will not cause the problem of exposed bottom, and at the same time, check the various defects caused by the elastic spandex yarn to ensure that any quality problems are dealt with in time.

The double-sided flat knitting collar is inspected, and then cloth is prepared, and then the above-mentioned double-sided flat knitting collar is washed with water (biological enzyme treatment, and soft oil cannot be added during the treatment process); wherein, the enzyme used in the biological enzyme treatment process is used. The composition of the lotion and the solubility of each component are shown in Table 3. As can be seen from Table 3, the enzyme lotion contains 2-6g/L biological enzyme, 0.5g/L sodium acetate and 0.5g/L acetic acid , the solvent is water; the biological enzymes used are CELLUSOFT ^TM enzymes produced by Novozymes (China) Biotechnology Co., Ltd., namely CELLUSOFT CR50*CX45'PROG 0120(B);

Then, the double-sided flat knitting collar after drying is finished with liquid ammonia. The principle and technical effect of liquid ammonia finishing are: ammonia gas is in a liquid state below -33 °C, and the viscosity and surface tension of liquid ammonia (NH ₃ ) are higher than that of water. Low, liquid ammonia can easily and quickly penetrate into the cotton fiber, so that the cotton fiber starts to expand from the core, the cross-section expands from flat to circular, the cavity diameter becomes smaller, and the surface is smooth. Due to the change of the fiber crystal structure, the internal stress is eliminated. , no longer twist, improved tensile strength and tear strength, even after repeated washing can still maintain a good hand (softness). After the double-sided flat knitting collar of the present invention is finished with liquid ammonia, the hand feeling and appearance of the finished product can be greatly improved.

The temperature at the cloth blanket is 100°C; the processing tension of the liquid ammonia finishing is: 2KG for the incoming cloth, 5KG for the upper and lower reaction zones, and 5KG for the outgoing felt.

Wherein, the liquid ammonia finishing can be carried out on the Italian LAFER liquid ammonia mercerizing machine, and the specific operations include: passing the dried double-sided flat knitting machine leader through the liquid ammonia treatment box with a guide cloth, and the guide cloth needs to be consistent with the width of the production leader, The seam head is straight and firm; and ensure that the machine does not stop in the middle, otherwise the color will be abnormal. If there is a stoppage, the double-sided flat knitting machine collar after drying needs to be clearly marked.

The double-sided flat knitting collar after the liquid ammonia finishing needs to be cleaned by washing water equipment. The composition of the washing water used and the solubility of each component are shown in Table 4. It can be seen from Table 4 that the washing FKS produced by Jiangxi Xianqiao Chemical Co., Ltd. is used as penetrant, DM-133 produced by Guangdong Demei Fine Chemical Co., Ltd. is used as low-temperature degreaser, and CIBA FLUID C produced by Huntsman Textile Dyeing (China) Co., Ltd. As a wrinkle-preventing agent, 6g/L of JSS soft oil (Magnasoft JSS) produced by Ming Kee Hong Kong Cleaning Products Co., Ltd. was added to the washing liquid as a softening agent.

The washing water treatment (over-soft oil treatment) specifically includes: putting the double-sided flat knitting collar after the liquid ammonia finishing into the washing water solution at a bath ratio of 1:18-40, and under the condition of 45-80° C. Wash with water for 30-60min.
