Problems solved by technology

The breaking strength of ordinary viscose fiber is smaller than that of cotton, about 1.6-2.7 cm / dtex, the elongation at break is 16%-22% higher than that of cotton, and the wet strength drops more, about 50% of the dry strength. The increase is about 50%, its modulus is lower than that of cotton, it is easy to deform under small load, and its elastic recovery performance is poor
Therefore, the fabric is prone to elongation and has poor dimensional stability

Embodiment 1

[0027] This embodiment is a colored core-spun yarn, which includes 45%-55% of viscose fiber, 45%-47% of nylon staple fiber, and 3%-5% of rabbit hair fiber in the core-spun yarn. , part or all of at least one fiber in the viscose fiber, rabbit hair fiber, and nylon staple fiber is a dyed fiber, and the dyeing and undyed viscose fiber, rabbit hair fiber, and nylon staple fiber are evenly and tightly Wrapped around the outside of long nylon fibers. The dyed fiber can be dyed monochrome or colored, wherein the type and quantity of the dyed fiber account for the total amount and / or proportion of the viscose fiber, rabbit hair fiber, and nylon staple fiber, which can be determined according to the user's requirements. Make a color standard according to the requirements of the color standard, and then follow the standard dyeing ratio of the color standard.

Embodiment 2

[0029] A kind of processing method of colored core-spun yarn, described processing method comprises the following steps:

[0030] The first step: a dyeing step, dyeing a part or all of at least one of the viscose fiber, rabbit hair fiber, and nylon staple fiber, the type and / or ratio of the dyed fiber, according to the set set by the color scale. The color standard is based on the color required by the customer. First, design and manufacture small samples of A and B. After confirmation by the customer, a sample card is prepared according to the designed color ratio, and a small amount of raw materials are organized to be handed over to the dyeing unit for dyeing according to the sample card.

[0031] The second step: post-dyeing treatment, spray oily water on the dyed fibers, and then simmer for more than ten hours. Since some of the oil on the fiber has fallen off after dyeing, it will affect the structure of the fiber, reduce the strength of the fiber, and some will cause s...

Abstract

The invention relates to the field of textile technology, in particular to a colored core-spun yarn, which comprises the following components in part by weight: 45 to 55 parts of viscose, 45 to 47 parts of nylon short fiber and 3 to 5 parts of rabbit fur fiber; at least one type of fiber in the three types of fibers is partial or full dyed fiber; and the dyed fiber and the undyed fibers are evenly and closely wound outside a nylon long fiber. The processing method for the core-spun yarn comprises the following steps: performing dyeing treatment on the fibers, spraying oil solution on the dyed fiber, and braising with water for a dozen of hours; and weighing the fibers with different colors in different ratios, mixing evenly, arranging the nylon long fiber and the fibers on a spinner, and evenly and closely winding the evenly mixed fibers outside the nylon long fiber through the spinner into a finished product of the core-spun yarn. In the blended yarn, the ratio of the various fibers and the ratio of the color of the various fibers are reasonable. Only a small part of fiber in the fiber needs to be dyed.

Description

technical field [0001] The invention relates to textiles and textile technology, in particular to a colored core-spun yarn and a processing method thereof. Background technique [0002] In the prior art, blended yarns are all selected from different fibers and spun by spinning machines, and the blended yarns after spinning or the cloth woven by blended yarns generally need to be dyed, and the existing dyeing technology generally needs to be dyed. The spun blended yarn or cloth is 100% dyed. This dyeing method not only consumes water and electricity, but also pollutes the environment, and the cost of dyeing will be higher. How to reduce the pollution caused by the blended yarn or the dyeing of the cloth woven by the blended yarn is a technical problem to be further solved. [0003] Because rabbit hair is a fine product in the wool fiber, its application is very extensive. The basic characteristics of rabbit hair fiber are: light, thin, warm, soft, fluffy, good hygroscopicit...
