Problems solved by technology

[0002] In the prior art, the fine sand machine adopts frequency conversion motor to prepare knitted fabric with slub effect, which is to control the different frequencies of the motor to control the thickness and thickness of slub; that is, the slub effect presented by it is regular and the shape is the same Therefore, the woven slub effect with the slub effect prepared by the prior art is too regular, and the slub effect is relatively stiff

preparation example Construction

[0031] A preparation process for self-forming slub-shaped knitted fabric, comprising the following steps:

[0032] (1) Pretreatment: After winding Sorona and cotton sand into one body through a two-for-one twister, weave a gray cloth on a circular knitting machine; place the embryos under high-temperature steam for steaming; the gray cloth has Sorona and cotton fibers;

[0033] After being strengthened by a two-for-one twister, the mechanical properties and processing properties of Sorona and cotton sand can be enhanced; the embryos are placed in the steam position, and the steam is used to heat the embryo cloth, so that the molecular chains of Sorona and cotton fibers are opened, and due to The volume of steam molecules is relatively small, and it will not wet the gray cloth in a large area, which is convenient for dyeing.

[0034] Sorona is a raw material produced by DuPont in the United States and can be purchased directly.

[0035] (2) Sorona dyeing: arrange the embryos a...

[0067] A preparation process for self-forming slub-shaped knitted fabric, comprising the following steps:

[0068] (1) Pretreatment: After winding Sorona and cotton sand into one body through a two-for-one twister, weave the gray cloth on a large circular knitting machine; place the embryos in 110-130°C high-temperature steam for steaming; the gray cloth is covered with Sorona and cotton fibers;

[0069] (2) Sorona dyeing: Arrange the embryos at 50°C, add Sorona auxiliaries and Sorona dyes, and raise the temperature to 110, 115, 120, 125, 130, 135, 140, 145 and 150°C respectively, as shown in Table 1 The embodiment A1~A9, insulation;

[0070] (3) Sorona cleaning: cool down the gray cloth to 70°C and perform initial cleaning; then increase the temperature to 85°C in turn for reduction cleaning;

[0071] (4) Sorona middle fixation: place the embryos in a humid environment at a high temperature of 150°C to fix the color of Sorona;

Embodiment B

[0101] A preparation process for self-forming slub-shaped knitted fabric, comprising the following steps:

[0102] (1) Pretreatment: After winding Sorona and cotton sand into one body through a two-for-one twister, weave the gray cloth on a large circular knitting machine; arrange the embryos to steam under steam at 110-130°C; arrange the embryos to steam under high-temperature steam Germ treatment; the greige has Sorona and cotton fibers on it;

[0103] (2) Sorona dyeing: place the embryos at 50°C and add Sorona additives and Sorona dyes, and heat up to 130°C respectively, and keep warm;

[0104] (3) Sorona cleaning: cool down the gray cloth to 70°C and perform initial cleaning; then increase the temperature to 85°C in turn for reduction cleaning;

[0105] (4) Sorona middle fixation: place the embryos in a humid environment at a high temperature of 150°C to fix the color of Sorona;

Abstract

The invention discloses a self-formed slubbed knitted fabric preparation process and a knitted fabric. The preparation process includes steps: (1) pretreatment; (2) Sorona dyeing; (3) Sorona washing;(4) Sorona centralizing; (5) cotton dyeing; (6) cotton washing; (7) gray cloth shaping. In the process, a Sorona dyeing temperature is controlled in a range of 120-140DEG C, and a cotton dyeing temperature is controlled in a range of 55-65DEG C. A slubbed effect of the knitted fabric is naturally formed without fixed slub length and distance. By limitation of the Sorona material and cotton dyeingtemperatures, resilience of the knitted fabric is embodied completely, and excellent effects of a finished fabric product are achieved. In addition, the slubbed effect of the product is naturally formed, the knitted fabric without fixed slub length and distance can be obtained, and irregular slub distribution is realized.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a preparation process of self-forming slub-shaped knitted fabric. Background technique [0002] In the prior art, the fine sand machine adopts frequency conversion motor to prepare knitted fabric with slub effect, which is to control the different frequencies of the motor to control the thickness and thickness of slub; that is, the slub effect presented by it is regular and the shape is the same Therefore, the weaving slub effect with the slub effect prepared by the prior art is too regular, and the slub effect is relatively stiff. Contents of the invention [0003] The purpose of the present invention is to propose a preparation process for self-forming slub-shaped knitted fabrics. In this process, the dyeing temperature of Sorona is controlled to be 120-140° C., and the dyeing temperature of cotton is controlled to be 55-65° C., so that the slub effect is formed naturally, w...
