Description

High-quality environmentally friendly core-spun yarn

technical field

The invention relates to the technical field of ring spinning, and belongs to core-spun yarn, in particular to a high-quality environment-friendly core-spun yarn.

Background technique

At present, most of the core-spun yarns on the market are made of ordinary spandex, which is prone to aging after a long time, and the elasticity decreases, and it is easy to wrinkle after wearing. Although there are also core-spun yarns made of polyester-spandex double filaments, the dimensional stability of the product is improved, but it is comfortable to wear. Poor performance, static electricity and airtight and deodorant. Due to the inherent defects of organic cotton fibers, organic cotton yarns in the market have poor spinnability, low spinning count and low strength. With the market's increasing requirements for environmental protection and the improvement of product quality, people need better softness, excellent moisture absorption and perspiration, comfort and durability, and good appearance, especially baby products need environmentally friendly and safe personal products. There are no similar reports on core-spun yarn products with a certain degree of elasticity, which use 200-300 English count compact spun cotton yarn as the core yarn, and are outsourced with organic cotton.

Long-staple cotton has the advantages of long fiber length and high strength, so it has the ability to develop ultra-high-count yarns. However, the ultra-high count yarn has low strength and limited wearing performance.

Organic cotton is a kind of pure natural and pollution-free cotton, which is one of the important components of sustainable agriculture. It is of great significance to ecological environmental protection, human health development and green natural ecological clothing. Since the performance of organic cotton fiber is lower than that of long-staple cotton, pure organic cotton fiber cannot be processed into high-count yarn products.

Contents of the invention

The purpose of this invention is to provide a high-quality environmentally friendly core-spun yarn, which has a reasonable structure, can make short organic cotton fibers into high-count yarns, improves the wearing performance and added value of fabrics, and can meet the requirements of children's clothing and close-fitting clothing. Safety requirements, improve product quality, and increase the utilization rate of ultra-high count yarn and organic cotton.

The purpose of the present invention is achieved in this way: a high-quality environmentally friendly core-spun yarn, the core yarn is composed of 200-300 English-count high-count yarn spun from 100% pure long-staple cotton fiber, and the core yarn is covered with a sheath It is made of twisted organic cotton fibers. The length of the main body of long-staple cotton constituting the core yarn is controlled above 38.5mm, and the micronaire value is 3.6-4.1. The outer sheath is spun from 100% organic cotton.

The yarn linear density of the core yarn is CJ200-CJ300 British branch, and the twist coefficient of the core yarn is 390-480. The core yarn is given an appropriate high twist to increase the elasticity of the yarn; or the core yarn and the yarn sheath are twisted with ZS or SZ to reduce the twist of the yarn and increase the softness and elasticity of the core-spun yarn.

The specification of the roving that constitutes the yarn cover is 4.0-5.0g/10m.

The specification of the roving that constitutes the yarn cover is 2.0-2.5g/10m.

Organic cotton is white organic cotton or natural colored organic cotton.

The number of organic cotton fiber rovings constituting the yarn sheath is 1-3.

The preparation method of high-quality environmentally friendly core-spun yarn includes the following two steps: the first step is the process of processing high-count yarn of long-staple cotton fiber: Qingganglian → pre-striping → coiling → combing → drawing frame → roving → Compact spinning frame → winding (parallel bobbin) → as core yarn.

The second step is the production process of processing outsourced organic cotton: Qingganglian → combing process (or not) → drawing frame → roving.

The spinning method of the present invention: the core yarn is 200-300 English-count high-count yarn spun from 100% pure long-staple cotton fiber, and the outsourcing organic cotton fiber is processed to form a pure cotton core-spun yarn, which is spun on a spinning frame At the same time, the long-staple cotton compact high-count yarn passes through the positioning guide wheel and guides the rear side of the guide roller (front roller) to merge with the organic cotton fiber strands after drafting, and the coated fibers are wrapped according to the traditional spinning method. Covering the surface of high-count yarn (core yarn), the spinning process is completed by twisting and winding. Cotton yarn-covered core-spun yarn gives full play to the advantages of the two fibers and makes up for their shortcomings, optimizing the structure and characteristics of the yarn. This method can make shorter organic cotton fibers into high-count yarns and improve fabric quality. Its wearing performance and added value can better meet the safety requirements of children's clothing and close-fitting clothing. It is an effective way to improve product quality.

To spin high-quality environmentally-friendly core-spun yarn, considering the characteristics of ultra-high-count yarn products, firstly make certain adjustments to the process flow, equipment selection and process parameters, and then roving one, two or three pure organic cotton fibers in the spinning process , and a pure long-staple cotton ultra-high count yarn of 200-300 British counts, and simultaneously feed and process it into a high-quality environmentally friendly core-spun yarn.

The advantages and beneficial effects of the present invention are: the outer fiber of the high-quality environmentally friendly core-spun yarn is organic cotton fiber, the core yarn is 200-300 British count ultra-high count yarn, the application range of ultra-high count yarn has been developed, and the ultra-high count yarn has been improved. The utilization rate of high-count yarn has opened up a new field of ultra-high-count yarn technology.

The high-quality environment-friendly core-spun yarn of the present invention combines the excellent performances of two kinds of cotton fibers, and can give full play to the advantages of long-staple cotton fibers and organic cotton fibers. Good abrasiveness, wide range of uses, suitable for processing baby products.

The invention has a reasonable structure, realizes making high-count yarns from shorter organic cotton fibers, improves the wearing performance and added value of fabrics, can meet the safety requirements of children's clothing and close-fitting clothing, improves product quality, and improves Utilization of super high count yarn.
