Pineapple grid corduroy double-sided fabric

Abstract

Disclosed in the present invention is a pineapple grid corduroy double-sided fabric, comprising front-side pineapple grid pattern corduroy units, cross-linking units, and back-side napped units. The three types of units are all formed by the perpendicular interweaving of warp yarns and weft yarns. The weft yarns comprise three groups of yarns, the first group of weft yarns and the warp yarns are interwoven to form a front-side corduroy structure, which is subjected to shearing and fiber splitting to form the front-side pineapple grid pattern corduroy units; the second group of weft yarns and the warp yarns are interwoven in a plain weave structure to form a cross-linking structure, and cross-linking warp yarns move back and forth between the front and back sides to combine the front and back sides; and the third group of weft yarns and the warp yarns are interwoven in a four-end broken twill weave structure to form an inner structure, which is subjected to fiber splitting and fiber raising to form a back-side napped structure. The weft yarns of the front-side corduroy structure and the back-side napped structure adopt ultra-fine polyester-nylon composite filaments, and after alkali reduction treatment, dense pile is formed on both sides of a fabric, so that a user obtains a soft and delicate plush feeling. The fabric has good water absorption, is suitable for making bathrobes, sleepwear and other products, has a unique pattern, and is comfortable and skin-friendly.

Description

A type of double-sided corduroy fabric Technical Field

[0001] This invention relates to the field of textiles, and in particular to a double-sided corduroy fabric in the shape of a pineapple pattern. Background Technology

[0002] Most commercially available fleece fabrics are made of 100% polyester or polyester-nylon, which inevitably have the following shortcomings: poor moisture absorption and breathability, and insufficient aesthetics and limited style. Fabric designers have made unremitting efforts to address these shortcomings to some extent, but the development of fabrics that simultaneously possess aesthetic appeal, good moisture absorption and breathability, and good functionality still needs further development. Inspired by corduroy and double-sided fleece fabrics, this design combines the advantages of both fabrics, creating a fabric structure that features both corduroy styles with various patterns on one side and single-sided fleece styles on the other, effectively compensating for the shortcomings of commercially available fleece fabrics. Firstly, corduroy offers diverse patterns, satisfying consumers' specific style requirements; secondly, single-sided fleece avoids the poor breathability problem caused by double-sided fleece. Technical issues

[0003] To improve the comfort of wearing fabrics, the purpose of this utility model is to provide a double-sided corduroy fabric with a pineapple pattern on one side and a single-sided short pile pattern on the other. By integrating the corduroy and single-sided pile structures in a design, and after weaving and finishing processes, the resulting fabric has a delicate pile feel on both sides, a three-dimensional and beautiful appearance, and significantly improved moisture absorption and breathability. The product offers significantly greater comfort than clothing made from ordinary polyester-nylon double-sided fleece. Technical solutions

[0014] Furthermore, the weight per square meter of the double-sided fabric is 225-235 g / m².

[0015] Furthermore, the width of the double-sided fabric is 162-166 cm. Beneficial effects

[0016] The beneficial effects of this invention are as follows: The front side of this invention is composed of a corduroy structure made of ultra-fine polyester-nylon composite yarns. After cutting and opening the fibers, it forms a pineapple-patterned corduroy with a beautiful and three-dimensional appearance and delicate, full pile. The reverse side is a four-end twill weave, which undergoes a special napping process to enhance the fabric's warmth and skin-friendly feel. Furthermore, the front and reverse sides are bonded together through cross-linking units, giving the fabric a composite double-sided fabric effect and avoiding the safety issues associated with adhesive bonding. The ultra-fine polyester-nylon composite yarns improve the fabric's water absorption and breathability. This fabric is suitable for making pajamas, bathrobes, and other bath and thermal wear products, featuring exquisite patterns and a comfortable feel. Attached Figure Description
