[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] Example 1

[0033] A one-piece pile super-elastic fluffy thermal fabric, the preparation method is as follows:

[0034] S1, grey fabric weaving: 40S / 1 spandex / viscose (40% / 60%) compact spinning + 40D spandex is used as the surface yarn (the amount of spandex accounts for about 6wt% of the whole grey fabric), 50D / 48FPBT polyester / polyester semi-dull light net DTY composite yarn is used as the middle layer yarn, and 300D / 288F high curl shrinkage polyester semi-dull light net DTY yarn is used as the bottom layer yarn. The cutting circle equipment is used to make a one-side loop and one-side raising grey fabric; the knitting needle arrangement, triangle and yarn arrangement diagram of the grey fabric are shown in Figures 1-2 , wherein a represents the surface yarn, b represents the middle layer yarn, and c represents the bottom layer yarn.

[0035] S2, grey fabric pre-setting: the grey fabric is pre-set by dry method at 200℃, 26m / min, to eliminate internal stress and stabilize the size;

[0036] S3, dyeing: the grey fabric is subjected to conventional dyeing, and the dyeing process is as follows:

[0037] ① degreasing: 80 degrees x 20 minutes.

[0038] ②Polyester + cationic:

[0039] Dyeing polyester with cationic dye, 95 degrees x 10 min;

[0040] Dyeing cationic polyester with cationic dye, 120 degrees x 60 min.

[0041] ③R / C: 80 degrees x 20 min.

[0042] ④Boiling alkali: 70 degrees x 10 min.

[0043] ⑤Dyeing viscose: using reactive dye, 85 degrees x 10 min;

[0044] ⑥Boiling alkali: 70 degrees x 20 min

[0045] ⑦Fixing;

[0046] S4, making soft nap: using a nap making slurry containing 40 g / L of T-HX300 nap making soft oil and 5 g / L of TWP stiffening agent to perform one-dip-one-nap softening and nap making treatment on the dyed fabric;

[0047] S5, carding and shearing: carding the shrunken and curled pile evenly, wherein the carding needle needs to be inserted to an appropriate depth so that it can card the inner layer of the nap, and then shearing the floating pile to make the pile height uniform;

[0048] S6, air flow drying: placing the sheared fabric in an air flow drying machine, using the rotation of the long machine box to constantly impact the nap surface of the fabric against the inner wall of the machine under a certain temperature and humidity, and finally forming a three-dimensional clustered large particle appearance to obtain an integrated pile super-elastic fluffy and warm fabric.

[0049] Performance test

[0050] I. To illustrate the improvement of the anti-pilling ability of the nap surface of the fabric of the present scheme by the selection and matching of raw materials, see the following comparative tests as verification:

[0051] Comparative Example 1: using 300D / 288F polyester semi-dull light net DTY yarn as the middle layer yarn, the temperature of the air flow drying machine is set to 110°C, and the processing time is 60 min.

[0052] Comparative Example 2: using 300D / 288F polyester semi-dull light net DTY yarn as the middle layer yarn, the temperature of the air flow drying machine is set to 110°C, and the processing time is 80 min.

[0053] Example 1: using 300D / 288F high crimping shrinkage polyester semi-dull light net DTY yarn as the middle layer yarn, the temperature of the air flow drying machine is set to 110°C, and the processing time is 80 min.

[0054] The steps of Comparative Examples 1-2 and Example 1 are consistent with the above-described implementation methods, except that the raw materials and the airflow tumble dryer process are compared using controlled variables. The anti-pilling grade and fabric fiber shedding grade test results of Comparative Examples 1-3 and Example 1 are shown in Table 1.

[0055] Table 1

[0056] Anti-pilling Fabric fiber shedding Comparative Example 1 2nd grade 6th grade Comparative Example 2 2.5th grade 6th grade Example 1 3rd grade 6th grade

[0057] As can be seen from Table 1, compared with Comparative Example 1, extending the processing time by 20 minutes in Comparative Example 2 has a certain effect on anti-pilling ability. However, Example 2 can achieve the improvement effect of anti-pilling simply by replacing ordinary polyester yarn with high-elastic semi-dull lightweight mesh DTY yarn. Not only is the improvement in anti-pilling more obvious and efficient, but the processing cost is also lower.

[0058] II. To illustrate how the use of spandex-containing elastic composite yarn in the surface layer of this solution enhances the appearance of large, three-dimensionally clustered particles, see... Figures 3-5 Comparative verification:

[0059] Figure 3 The lower fabric is a cross-sectional micrograph of the loop-cut fleece fabric from Example 1. Figure 3 Microscopic cross-section of the upper fabric, which is a loop-cut fleece fabric woven with surface yarns without the addition of 40D spandex. Figure 4 This is the napped front side of the fabric in Example 1. Figure 5 The napped side of the fabric is made without adding 40D spandex to the surface yarn. From Figure 3 The comparison is visible and Figure 5 It is evident that the density of loop-pile fabric woven without the addition of 40D spandex to the surface yarn is relatively low, the number of fibers per unit area is sparse, and the thickness is slightly reduced. Furthermore, it is prone to shedding more fibers during dyeing and air-drying processes, failing to achieve the desired results. Figure 4 The established goal is to achieve a fleece style. The preparation method of the one-piece fleece super elastic fluffy and warm fabric in this solution, through special selection of yarns, not only increases the density of the fleece, ensuring that the fabric has sufficient thickness and density, but also breaks through the airflow blasting intensity that traditional cut loop fleece fabrics cannot withstand, thus enabling the fleece to be processed into clusters. As a result, the cut loop fleece fabric of this solution presents a special appearance of three-dimensional clustered large granular fleece that cannot be achieved by fabrics on the market.

[0060] III. To illustrate the effect of the pilling paste formula in this solution on improving the anti-pilling ability and pilling effect of the fabric, the following comparative test is provided for verification:

[0061] Comparative Example 3: In step 4, a raising paste containing 20 g / L of T-HX300 raising softening oil was used to treat the dyed fabric.

[0062] Comparative Example 4: The dyed fabric was treated with the raising paste containing 60 g / L of T-HX300 raising softener and 5 g / L of TWP stiffener in Step 4.

[0063] Comparative Example 5: The dyed fabric was treated with the raising paste containing 40 g / L of T-HX300 raising softener in Step 4.

[0064] Example 1: The dyed fabric was treated with the raising paste containing 40 g / L of T-HX300 raising softener and 5 g / L of TWP stiffener in Step 4.

[0065] The steps of Comparative Examples 3-5 and Example 1 are consistent with the above-described embodiment, and only the raising paste formula in Step 4 is controlled for comparison. The anti-raising ball grade and the raising effect of Comparative Examples 3-5 and Example 1 are shown in Table 2.

[0066] Table 2

[0067] Anti-pilling Pilling effect Comparative Example 3 3rd grade Difficult to pill Comparative Example 4 2nd grade Very easy to pill Comparative Example 5 2.5th grade Easy to pill Example 1 3rd grade Easy to pill

[0068] As can be seen from Table 2, compared with Comparative Example 5, Comparative Example 3 can improve the raising ball problem by reducing the amount of raising softener, but it is difficult to raise the processing due to insufficient softening; and Comparative Examples 4-5 have high overall softening degree, which makes it easy to raise, but leads to too soft fabric, which performs poorly in the raising ball test. Example 2, by compounding the raising softener and the stiffener, makes the clustered three-dimensional nap formed by the semi-dull light net DTY yarn of high-elasticity polyester have good raising effect, and the skin layer is not easy to raise ball, the hand feeling is soft and comfortable, and the overall achieves the ideal fabric effect.
