Description

A kind of mulberry fiber blended fabric and its production process

technical field

The invention relates to a blended fabric and its production process, in particular to a mulberry fiber blended fabric and its production process.

Background technique

At present, the natural fibers used in clothing textiles include: cotton, wool, silk, hemp and other types. The fundamental properties of these fibers determine the performance and style characteristics of their fabrics. That is to say: the performance and style characteristics of a fabric are subordinate to the type of fibers used in it. And every kind of natural fiber has its inherent weakness, such as the hemp fiber has high strength and the fabric is very cool, but the softness and elasticity are poor, and the itching feeling of people when wearing it has not been solved so far. Silk is soft and has bright luster, but too soft makes the fabric have no body, and the strength and shape retention of the fabric are also poor. All of these make the diversity of textile products limited and have a negative impact on the development of textiles. At the same time, the increasingly updated consumer demand and market demand also challenge the varieties and resources of traditional natural fibers, and the demand for developing new natural fibers is becoming stronger and stronger.

Mulberry trees have been planted in my country for thousands of years, but the utilization of mulberry trees has been mainly "planting mulberry and raising silkworms". In addition, Morus alba is used as a traditional Chinese medicine for relieving asthma and clearing lung heat. The cellulose fibers rich in mulberry bark have not been used as textile raw materials because their length, strength, and length uniformity are not suitable for low-tech textile production. At present, there is no report of mulberry fiber blended fabric at home and abroad (Novelty Search Report No. 2003079 of the Workstation of the Science and Technology Project Consulting and Achievement Novelty Search Center of Higher Education Institutions (Sichuan University).

Mulberry fiber is a natural fiber obtained by degumming the Morus alba peeled from mulberry branches. It has good hygroscopicity, coolness, good cold feeling, silky cross-section and luster.

Contents of the invention

The mulberry fiber is mainly distributed in the outer layer of the yarn, and the long-staple cotton fiber is mainly distributed in the inner layer of the yarn; the design weight of the fabric is: 80～

400g/m ² .

The weave of the above-mentioned woven fabric can adopt plain weave, twill weave, satin weave, small pattern weave or jacquard weave;

A kind of above-mentioned mulberry fiber and long-staple cotton is the production technology of the blended fabric of raw material, and its technological process is: after the mulberry fiber strip and cotton sliver are through drawing, roving, spun process, the pre-weaving preparation process of woven fabric is in Fabric is woven on a loom; knitted fabrics are woven into knitted products or semi-finished products on a fine-needle flat knitting machine after the tube and twisting process; dyed fabrics are woven after dyeing the cheese. It is characterized by:

A, drawing: the mulberry fiber strips and cotton slivers that have been made into slivers in the previous spinning process are first combined, secondly combined and thirdly combined on the drawing frame, so that the mulberry fiber and cotton fiber are fully mixed;

B. Roving and spun yarn: When drafting and twisting are carried out with greater tension, the mulberry fiber is mainly distributed on the outer layer of the yarn, and the long-staple cotton fiber is mainly distributed on the inner layer of the yarn;

C. Weaving: Otto Connor automatic winding machine is used to make non-joint yarn for winding; modified starch low-temperature sizing process is used for sizing woven fabrics; small machine tension is used under the premise of meeting the fabric machine requirements when weaving woven fabrics on board.

Compared with prior art, the beneficial effects of the present invention are:

1, the mulberry fiber blended fabric of the present invention has adopted this novel nature of mulberry fiber and long-staple cotton fiber to blend into yarn and weave fabric. A new category of natural fiber fabrics was developed. The fabric has good hygroscopicity and vapor permeability; it feels cool but soft, and has good cold feeling without itching; the fabric has a silky luster; it is a new type of green natural fiber textile.

2. The mulberry fiber with a length of 10-45mm is blended with long-staple cotton, which solves the technical problem of difficulty in pure spinning of mulberry fiber into yarn.

3. With the drafting and twisting process of roving and spun yarn, the long-staple cotton fibers with a large content are mainly distributed in the inner layer of the yarn, forming the main body of the yarn, so that the yarn can obtain better mechanical properties. The mulberry fiber with less content is mainly distributed in the outer layer of the yarn, so that the mulberry fiber fabric can fully demonstrate the good wearability of the mulberry fiber with good hygroscopicity, coolness, good cold feeling, silk-like cross-section and luster. This solves the problem that the mulberry fiber components in the common spinning process make yarn difficult; the mulberry fiber components are small and the mulberry fibers are evenly distributed in the yarn, and the characteristics of the mulberry fibers cannot be fully reflected. weakness.

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
