Embodiment Construction

[0009] The present invention is described below in conjunction with specific embodiments.

[0010] The present invention adopts the knitting of bamboo fiber and cotton blended yarn and spandex yarn, and bamboo fiber and cotton blended yarn constitute the front side of the fabric, and the bottom surface is spandex yarn, and the weight of the blended yarn of bamboo fiber and cotton The ratio is 45:55, and after adding spandex for knitting, the weight ratio is bamboo fiber: cotton: spandex=43.2:52.8:4, the blended yarn count of bamboo fiber and cotton is 50S, and the spandex count is 70D.

[0011] Described bamboo fiber adopts following extraction process to prepare and obtain:

[0012] A) pretreatment: the bamboo is divided into bamboo slices after cleaning;

[0013] B) Acid bath and drawing for the first time: put the above-mentioned bamboo slices into a sulfate solution added with denaturant 1815 for cooking and drawing. The cooking temperature is 49°C and the cooking time is...

Abstract

The invention relates to the technical field of novel fibres, in particular to a composite fabric of pure natural bamboo fibres, cotton and spandex. The composite fabric is characterized in that the composite fabric is knitted by the bamboo fibres, cotton blended yarn and spandex yarn; and the bamboo fibres and cotton blended yarn form the front surface of the fabric, and the bottom surface is made of the spandex yarn; the weight ratio of the bamboo fibres to the cotton blended yarn is 45:55; the weight ratio of the bamboo fibres to the cotton to the spandex is 43.2:52.8:4 after the addition of the spandex yarn; and the number of the bamboo fibres and the cotton blended yarn is between 32 and 60S, while the number of the spandex is between 40 and 70D. The composite fabric has the advantages that the extracted bamboo fibres have the fineness and whiteness similar to those of ordinary viscose fibres, excellent brute force, higher toughness and abrasive resistance and excellent spinnability; moreover, the fabric made from the bamboo fibres has excellent hydroscopic property and ventilation property and the functions of smoothness, velour, antibiosis and deodorization; and the composite fabric can be widely used in the fields of underwear products, home leisurewear and the like.

Description

[technical field] [0001] The invention relates to the technical field of novel fibers, in particular to a composite fabric made of pure natural bamboo fiber, cotton and spandex. [Background technique] [0002] Bamboo fiber is a new natural, green and environmentally friendly fiber. Its basic raw material comes from the evergreen plant bamboo in nature. Bamboo fiber has hygroscopicity, air permeability and drapability, these characteristics are superior to cotton fabrics, and more importantly, its natural antibacterial properties, the same number of bacteria observed under a microscope, the bacteria on cotton products did not change, while About 75% of the bacteria on the bamboo fiber are killed after 24 hours, which is unmatched by other textile materials. However, although the characteristics of bamboo fiber itself are very good, due to the low strength of pure bamboo fiber, it brings great difficulties to weaving, dyeing and finishing of knitting, etc., which greatly redu...
