Embodiment 1

[0047] The preparation method of hygroscopic and antibacterial knitted fabric is as follows:

[0048] (1) Preparation of mixed filaments:

[0049] Mixed filaments are extruded on the same spinneret;

[0050] Divide the PTT melt (intrinsic viscosity 0.96dL / g) into two paths: one path is directly extruded after distribution; the other path is distributed with PBT melt (intrinsic viscosity 1.1dL / g) in parallel composite spinning Extrusion; the spinneret m ("H" shape spinneret) and the spinneret n (circular spinneret) that are extruded and flowed through after being distributed in parallel composite spinning mode ) is 1:6; the mass ratio of the PTT melt through the spinneret n to the mass of the PBT melt is 50 to 50, and the ratio of the equivalent diameter of the spinneret m to the spinneret n is 1: 1;

[0051] Among them, such as figure 1 As shown, the "H" shape of the "H"-shaped spinneret hole is composed of two vertical sides, one horizontal side and four circular ends. Th...

Embodiment 2

[0063] The preparation method of hygroscopic and antibacterial knitted fabric is as follows:

[0064] (1) Preparation of mixed filaments:

[0065] Mixed filaments are extruded on the same spinneret;

[0066] Divide the PTT melt (intrinsic viscosity 1dL / g) into two paths: one path is directly extruded after distribution; the other path is distributed and extruded together with PBT melt (intrinsic viscosity 1.15dL / g) Out; the spinneret m ("H" shape spinneret) and the spinneret n (circular spinneret) that are extruded and flowed through after being distributed according to the parallel composite spinning method The ratio of the number of spinnerets is 1:7; the mass ratio of the PTT melt passing through the spinneret n to the mass of the PBT melt is 50 to 50, and the ratio of the equivalent diameter of the spinneret m to the spinneret n is 1:1 ;

[0067] Among them, the "H" shape of the "H"-shaped spinneret hole is composed of two vertical sides, one horizontal side and four ci...

Embodiment 3

[0076] The preparation method of hygroscopic and antibacterial knitted fabric is as follows:

[0077] (1) Preparation of mixed filaments:

[0078] Mixed filaments are extruded on the same spinneret;

[0079] Divide the PTT melt (intrinsic viscosity 1.03dL / g) into two paths: one path is directly extruded after distribution; the other path is distributed with PBT melt (intrinsic viscosity 1.16dL / g) in parallel composite spinning Extrusion; the spinneret m ("H" shape spinneret) and the spinneret n (circular spinneret) that are extruded and flowed through after being distributed in parallel composite spinning mode ) is 1:6; the mass ratio of the PTT melt through the spinneret n to the mass of the PBT melt is 50 to 50, and the ratio of the equivalent diameter of the spinneret m to the spinneret n is 1: 1;

[0080] Among them, the "H" shape of the "H"-shaped spinneret hole is composed of two vertical sides, one horizontal side and four circular ends, the two vertical sides and on...

Abstract

The invention relates to a moisture-absorbing and antibacterial knitted fabric and a preparation method thereof. Cotton fiber is used as the raw material of the veil, mixed fiber yarn is used as the raw material of the intermediate yarn, and fine denier "H" shaped PET fiber is used as the raw material of the ground yarn to carry out three-thread plating weaving and antibacterial finishing A hygroscopic and antibacterial knitted fabric is obtained; wherein, the blended filaments are extruded on the same spinneret, and the PTT melt is divided into two paths: one path is directly extruded after being distributed (flowing through the "H" shaped spinneret hole m) , the other way is distributed with the PBT melt in parallel composite spinning mode and then extruded (flowing through the circular spinneret n), which is made according to the FDY process; the hygroscopic and antibacterial knitted fabric is hygroscopic, quick-drying and antibacterial The efficiency indexes are all good, and the curling directions of the single filaments of the blended filaments in the finally prepared hygroscopic and antibacterial knitted fabric are randomly distributed. The invention solves the problem that "stripes are uneven" when the two-component composite fiber is applied to the hygroscopic and antibacterial knitted fabric, and the prepared hygroscopic and antibacterial knitted fabric has better hygroscopic and antibacterial properties.

Description

technical field [0001] The invention belongs to the technical field of polyester fibers, and relates to a hygroscopic and antibacterial knitted fabric and a preparation method thereof. Background technique [0002] As consumers gradually increase their requirements for textiles, more and more bi-component composite fibers are used in the design of hygroscopic and antibacterial knitted fabrics. Curl is an important indicator of fibers, affecting the textile processing and final product characteristics and application performance. [0003] In the big family of two-component composite fibers, the side-by-side two-component composite fiber is an important member. It uses the difference in thermal shrinkage properties of the two components to make the fiber bend away from the fiber axis, showing a permanent Three-dimensional spiral crimp for a wool fiber-like curl. The crimping of this kind of fiber does not require the deformation processing of ordinary thermoplastic fibers wh...
