Embodiment 1

[0057] see Figure 1 to Figure 4 Shown, the present invention provides a kind of method that can change fabric structure, comprises the steps:

[0058] S1, using ring spinning to prepare dewy composite core-spun yarn 8;

[0059] The fiber roving 6 is a cotton roving, which is composed of fibers with a dry weight of 7.8g / 10M and a cut length of 35-60mm; the polymer filament 2 is a single-component low-melting polyester filament with a fineness of 150D; the elastic fiber is long Silk 1 is spandex filament with a fineness of 40D.

[0060] On the ring spinning frame, the cotton roving is fed from the bell mouth, and the cotton roving sliver is obtained after being drafted by the drafting device 7, wherein the total drafting ratio of the drafting device is 24.6, and the drafting ratio of the rear drafting area is 1.5; Spandex filament 1 and low-melting point polyester filament 2 pass through the first tension disc 4 and the second tension disc 3 respectively, pass through the god...

Embodiment 2-4

[0076] The method for changing the fabric structure provided in Examples 2-4 is different from that in Example 1 in that the heat treatment temperatures are 90°C, 100°C, and 120°C, respectively. Except for the above differences, other operations are basically the same and will not be repeated here.

[0077] The properties of the fabrics prepared in Examples 1-4 were compared, as shown in Table 2 below.

[0078] Table 2 embodiment 1-4 and comparative example 1 prepare the fabric performance comparison

[0079]

[0080] According to Table 2, as the heat treatment temperature increases, the yarn diameter of the obtained fabric is smaller, the surface density is larger, the coil length is shorter, the anti-pilling ability is stronger, and the mechanical properties are better. However, when the heat treatment temperature reaches 120°C, the appearance of the fabric becomes denser, the handle becomes harder, and the comfort of the fabric begins to deteriorate.

[0081] It should...

Embodiment 5-6

[0083] The method for changing the fabric structure provided by Examples 5-6 is different from that of Example 1 in that the heat treatment time is 30s and 10s respectively. Except for the above differences, other operations are basically the same and will not be repeated here.

[0084] project Example 1 Example 5 Example 6 Heat treatment time / s 60 30 10

[0085]The properties of the fabrics prepared in Comparative Example 1 and Examples 5-6 are shown in Table 3 below.

[0086] Table 3 embodiment 1, embodiment 5-6 and comparative example 1 prepare the fabric performance comparison

[0087]

[0088] According to Table 3, with the prolongation of heat treatment time, the higher the degree of shrinkage of the yarn, the tighter the fabric, and the stronger its surface density, maximum bonding strength, anti-pilling ability, and tensile breaking strength. When the heat treatment time is 60s, the obtained fabric 12 has the best mechanical properties ...

Abstract

The invention provides a method for changing a fabric structure, and belongs to the field of textile. The method includes: blending polymer filaments, elastic fiber filaments and fiber rovings to obtain white-ground composite core-spun yarns; weaving the yarns to obtain a fabric; and subjecting the obtained fabric to local heat treatment. Based on the characteristic of heat shrinkage of the polymer filaments, the heat treatment enables the polymer filaments in the white-ground composite core-spun yarns to be heated and shrunk, the yarns are shrunk, and then the fabric is driven to be shrunk, so that the density of the fabric is increased; based on the characteristic of heat melted adhesion of the polymer filaments, the heat treatment enables melt bonding fixation to occur at the overlap ofthe yarns. Therefore, the heat-treated area of the fabric loses elasticity, the fabric structure is compact, and the non-heat-treated area still keeps elasticity; the heat treatment helps change thestructure of the fabric, and improve the mechanical properties, pilling resistance and other properties of the fabric.

Description

technical field [0001] The invention relates to the textile field, in particular to a method capable of changing the fabric structure. Background technique [0002] The fabric is formed by many yarns crossing, knotting and connecting to form a stable relationship. It is widely used in clothing manufacturing, decorations, medical supplies and other industries. With the improvement of living standards, people put forward higher requirements for the aesthetics and functionality of fabrics. Those skilled in the art have carried out a series of research and development on fiber materials and fabric post-processing methods in order to obtain new fabric preparation methods and realize the preparation of fabrics used in fashion, joint protection, household items, etc. [0003] The patent application with the application number CN201610941186.X discloses a low-melting fiber towel and its processing method. The low-melting fiber core-spun yarn is used as the warp or weft, and the low...
