Description

TECHNICAL FIELD

[0001] The present application relates to a one-way moisture-conducting simulated woven warp-knitted lining fabric and a production process, and belongs to the technical field of textiles. BACKGROUND

[0002] Lining fabric is a main auxiliary material in the garment industry, which is applied to the inner layer of garments to play the roles of shape retention, stiffness, reinforcement, and aesthetics. Nowadays, non-woven lining fabric is widely used due to its simple production process and low price, but it has problems such as poor water resistance, poor fastness, and poor shape retention. Woven lining fabric has the advantages of strong tension, water resistance, and less deformation, but it is more expensive than non-woven lining fabric due to its complex production process and low yield. As an auxiliary material for garments, the stability of the shape and size of the lining fabric is the primary condition, so it is very important to produce lining fabric with stable longitudinal and lateral dimensions. Moreover, with the improvement of living quality, there is an increasing demand for functional lining fabric, but non-woven lining fabric and woven lining fabric have a hard hand feeling and poor air and moisture permeability. The existing lining fabric improves the air and moisture permeability by coating the fabric or opening heat dissipation holes on the surface of the lining fabric, but the coating makes the fabric feel hard and not resistant to washing, and the heat dissipation holes are sealed due to the close contact between the fabric and the lining caused by human movement, so the lining fabric does not have good ventilation and heat dissipation performance. Cotton lining fabric can solve the above problems, but it also brings problems such as easy wrinkling, poor fabric elasticity, and poor shape retention, which is contrary to the original intention of using lining fabric.

[0003] Therefore, it is an urgent problem in the field to design a lining fabric with stable size, good air and moisture permeability, soft hand feeling, high yield, low cost, and certain shape retention. SUMMARY

[0052] 1. Dimensional stability test method:

[0053] Dimensional stability is reflected by the shrinkage rate after washing. The requirements for dimensional change after washing shall be in accordance with FZ / T64025—2011, with the longitudinal dimensional change rate being -2.0% to 0.5% and the transverse dimensional change rate being -1.5% to 0.5%.

[0141] A unidirectional moisture-wicking mock-shuttle-woven warp-knitted lining fabric and production process are composed of the following mass percentages: 30D24f semi-dull polyester FDY is 15.79%, and 32s polyester-cotton blended yarn is 84.21%.

[0142] 1) Material selection: 30D semi-dull polyester filament FDY and 32s polyester-cotton blended yarn are used as raw materials;

[0143] 2) Beaming: according to the width of 168 cm and the weft density of 9.4 wpc, the beaming head fraction is calculated to be: GB1 is 8×714, GB2 and GB3 are both 8×357, according to the process requirements that the GB1, MS1 pass rate is 100%, the GB2 pass rate is 1 pass 1 empty, and the GB3 pass rate is 1 empty 1 pass.

[0144] The beaming site temperature is 25±1℃, and the relative humidity is 65±5%. Higher and stable temperature and humidity are conducive to the twist stability and surface softness of polyester, avoiding entanglement between yarns, and are beneficial to the production of warp-knitted products.

[0145] 3) Weaving: using a tricot warp knitting machine for weaving;

[0146] Machine type: tricot warp knitting machine HKS 3

[0147] Machine number: 24 needles

[0148] Machine width: 186 inches

[0149] Warp knitting structure:

[0150] GB1 comb: 1-2 / 1-0 / / ;

[0151] GB2 comb: 1-1 / 1-1 / 0-0 / 0-0 / / ;

[0152] GB3 comb: 0-0 / 0-0 / 1-1 / 1-1 / / ;

[0153] Raw materials and threading method:

[0154] GB1 comb: 30D semi-lustrous polyester filament FDY, full threading;

[0155] GB2 comb: 32s polyester-cotton blended yarn, 1 threading 1 empty;

[0156] GB3 comb: 32s polyester-cotton blended yarn, 1 empty 1 threading;

[0157] Input the structure winding number, let-off amount and drawing density, etc. into the computer display screen of the control cabinet, save and load the machine file, and then start the machine. After weaving, the rough cloth is obtained, weighed, bagged, and stored in the warehouse.

[0158] 4) Finishing: ① washing; ② setting; ③ dyeing and finishing; ④ tensioning; ⑤ drying;

[0159] 5) Detection and packaging.

[0160] After the above process, the unidirectional moisture-wicking imitation shuttle-woven warp-knitted base cloth fabric of the embodiment can be obtained.

[0161] The specific parameters of the process of the embodiment are shown in Table 4.

[0162] Table 4

[0163]

[0164]

[0165] Comparative Example 1 changed the material of GB2 and GB3 from polyester-cotton to polyester, and the formed lining fabric could not form a certain difference in hydrophilic and hydrophobic properties of two sides due to poor moisture absorption of polyester, so it could not form the one-way wetting effect. The one-way wetting warp-knitted lining fabric was prepared according to the method of Example 1, with the difference that Comparative Example 2 omitted the full-width lining weft knitting step of MS1, and other conditions were the same as those of Example 1. Compared with Example 1, the water washing dimensional change rate of Comparative Example 2 decreased by 4.8% after the full-width lining weft knitting step of MS1 was omitted, the dimensional stability of the fabric was poor, and the one-way wetting index was 2, which did not reach the standard. This shows that the full-width lining weft knitting step can not only strengthen the transverse stability, but also improve the wetting performance.

[0166] Table 5

[0167]

[0168] As shown in Table 5, the dimensional stability of Comparative Example 1 was the best, because polyester is a chemical fiber, and the water washing shrinkage is small. The polyester-cotton blended yarn contains cotton, and the water washing shrinkage of cotton is large after washing, so the dimensional stability of Comparative Example 1 is the best, and the dimensional stability of Comparative Example 2 is the worst. The warp-knitted fabric has excellent longitudinal dimensional stability due to the longitudinal loop structure, and the full-width lining weft knitting strengthens the transverse stability, so the dimensional stability of Examples 1 and 2 is obviously improved, but the stability of Example 2 decreases by 0.2% due to the longer float. The one-way wetting effect of Example 1 is the best, because the difference in hydrophilic and hydrophobic properties of the yarns on the process front and back sides forms a wetting gradient, realizing the one-way wetting function. The one-way wetting function of Example 2 decreases slightly compared with Example 1, because the change in the number of laps changes the float into a larger area, which makes the one-way wetting function decrease slightly. Comparative Examples 1 and 2 do not have the one-way wetting function. In Comparative Example 1, the material of GB2 and GB3 is changed from polyester-cotton to polyester, and the formed lining fabric could not form a certain difference in hydrophilic and hydrophobic properties of two sides due to poor moisture absorption of polyester, so it could not form the one-way wetting effect. In Comparative Example 2, the full-width lining weft knitting is omitted, so that the process front side lacks sufficient hydrophobic yarns, and the hydrophobic fiber of GB1 is too thin to form a wetting gradient with the process back side, so it forms one-way wetting, but the lining fabric becomes sparse and the gap becomes large due to the lack of full-width lining weft knitting, so the index is one level higher than that of Comparative Example 1.

[0169] Although the present application has been disclosed with reference to the preferred embodiments, it is not intended to limit the present application, and any person skilled in the art can make various modifications and modifications without departing from the spirit and scope of the present application, so the protection scope of the present application should be defined by the claims.
