Description

Yarn for sweater and method for producing sweater

technical field

The invention relates to a yarn for sweaters and a method for producing sweaters, belonging to the field of textile processing.

Background technique

With the development of the economy and the improvement of people's living standards, the concept of consumption is constantly updated, people pay more and more attention to the quality of life and the living environment, and the functional requirements for clothing are also getting higher and higher, especially for the health care and hand feeling of clothing. , quality and other aspects of the requirements are constantly improving.

At present, there is an urgent need to develop new products that meet the needs of the times and have various functions to meet consumers' health, comfort, and high-quality clothing needs. For example, the publication number is CN101317700, and the name of the invention is a woolen sweater and its production process. The raw material of the woolen sweater is a yarn blended with spun silk, modal fiber, milk fiber and cashmere. The weight of the spun silk is The ratio is 50-60%, the modal fiber weight ratio is 20-30%, the milk fiber weight ratio is 10-15%, and the cashmere fiber weight ratio is 5-15%. The wool sweater has natural wrinkle resistance, high moisture absorption and warmth retention, and has a smooth hand.

In addition, sweaters not only need to keep warm, but also have anti-ultraviolet function, which can not only accelerate the microcirculation of the human body, promote metabolism, but also prevent the damage of ultraviolet rays to the skin, and have certain health care and protection effects on the human body.

Therefore, need researcher to constantly research and develop the woolen sweater yarn that market needs.

Contents of the invention

The object of the present invention is to provide a yarn for sweater which has natural anti-ultraviolet shielding function and does not change the original characteristics of the sweater.

Another object of the present invention is to provide a method for producing sweaters using the sweater yarn.

In order to achieve the purpose of the present invention, a yarn for sweaters of the present invention is composed of the following components in weight percentage: wool fiber 35-45%, modal fiber 35-45%, pearl fiber 15-25%.

Wherein, the yarn count of the sweater yarn is 32S/2.

The preferred components and content are: wool fiber 40%, modal fiber 40%, pearl fiber 20%.

The wool fiber can adopt wool, rabbit hair, camel hair fiber etc. commonly used in this field.

The pearl fiber is a functional cellulose fiber made by blending and spinning nanometer pearl particles and viscose. The fabric made of this fiber material feels smooth and soft, and the surface of the fabric presents a pearl-like luster, and has good hygroscopicity, non-toxic and non-irritating to the human body. Whitening effect. The calcium carbonate component has far-infrared emission function and anti-ultraviolet function, which can not only accelerate the microcirculation of the human body, promote metabolism, but also prevent the damage of ultraviolet rays to the skin, and has certain health care and protection effects on the human body.

The modal fiber is regenerated cellulose fiber with high wet modulus. Modal fiber has good elasticity and toughness, which reduces the phenomenon of broken ends during processing. It has good dyeing performance and remains bright as new after repeated washing. Its good shape and dimensional stability make the fabric have natural wrinkle resistance.

All the fiber raw materials of the present invention are short fibers, and all of them are commercially available.

The yarn of the present invention can be used as a raw material to produce various wool fabrics according to the existing wool fabric production process, such as sweaters, fine imitation and woolen fabrics, etc., to meet market demand.

Yarn of the present invention is processed into sweater, and its production technology comprises the following steps:

1) Select the raw material of white raw yarn: select the yarn blended with 35-45% wool fiber, 35-45% modal fiber and 15-20% pearl fiber as raw material;

2) dyeing;

3) Rewinding: Eliminate yarn defects and lubricate the dyed yarn, and package it into a package;

4) Weaving piece: knitting the various tissue parts of the sweater on the flat knitting machine;

5) Sleeve;

6) flat car;

7) hand sewing;

8) Washing: Clean the stitched sweater and shrink it at the same time. The weight percentage of the detergent (such as 209 detergent) is 1-1.5%, and the weight of the softener (such as collagen softener) is 1-1.5%. The percentage is 1.5-2%, the treatment temperature is 35-40°C, the bath ratio is 1:30, and the time is 15-20 minutes;

9) drying;

10) Ironing.

Wherein, the dyeing can be carried out at room temperature to dye the white raw yarn according to the color required by the fabric design, and can be carried out by adopting a conventional process in the art.

The woven pieces are the tissue parts of the sweater knitted on the flat knitting machine.

The cuff is used to sew up the tissue parts of the sweater, and the stitches are even, straight and firm.

The flat car is sewed with anti-stretch webbing at the shoulder seam, and the shoulder width is shaped to resist deformation.

The hand-stitching is performed on the hem, the cuff rib and the intersection of the hem seam and the bottom seam of the sleeve for reinforcement and back-stitching, wrapping thread ends and other auxiliary staples.

The drying is performed by placing the sweater in a tumble oven at a temperature of 45°C.

The ironing is to select an ironing board according to the size of the sweater, and use a steam iron to iron.

The yarn count of the yarn is 32S/2.

According to the characteristics of different fiber raw materials, the present invention rationally arranges the weight ratio of each fiber to highlight the characteristics of each fiber, integrates the advantages of various fibers, not only maintains the basic performance of sweaters, but also has the function of anti-ultraviolet shielding. It can not only accelerate the microcirculation of the human body, promote metabolism, but also prevent the damage of ultraviolet rays to the skin, and has certain health care and protection effects on the human body. It can be processed into spring, autumn and winter clothing with comfortable wearing and excellent performance. The product of the present invention selects a reasonable fiber dosage after many experiments, and makes the product of the present invention obtain the best function while reducing the production cost.
