Problems solved by technology

[0007] From "Structural Characteristics and Performance Analysis of Bamboo Fiber", it can be seen that although bamboo fiber itself has excellent properties such as moisture absorption and air permeability exceeding other fibers, as well as natural antibacterial properties, due to the low strength of pure bamboo fiber, it is difficult for knitting, weaving, Dyeing and finishing brings great difficulties, which greatly reduces the wearing performance of the woven fabrics

Embodiment 1

[0019] The fabric is made of blended yarn of 60% bamboo and 40% cotton, yarn count J40 S , the twist coefficient is 340, and the blended yarn of bamboo and cotton is obtained by the application of Nylon dense spinning technology, and it is spun with DuPont Lycra silk (spandex) to ensure the stability of the fabric size. The equipment used: 24G Delo single-sided loom, Obtaining the reverse side is Lycra silk (spandex) fabric, and the front is the woven knitted fabric of bamboo and cotton blended yarn fabric.

[0020] Net billet physical index:

[0021] Net blank width: 171cm dry weight: 180g / m 2 Strength: 150N Shrinkage: 3.4 / 4.5.

Embodiment 2

[0023] The fabric is made of blended yarn of 70% bamboo and 30% Tencel, and the yarn count is J32 S , the twist coefficient is 345, and the blended yarn of bamboo and tencel is obtained by applying the nylon dense spinning technology, and it is spun with 20D nylon yarn to ensure the stability of the fabric size. It is made of 20D nylon silk fabric, and the front is woven and knitted fabric of bamboo and tencel blended yarn fabric.

[0024] Net billet physical index:

[0025] Net blank width: 171cm dry weight: 135g / m 2 Strength: 142N Shrinkage: 0.6 / 1.0.

Embodiment 3

[0027] The fabric is bamboo fiber Modal Lycra single jersey

[0028] MODAL fiber is a new type of high-tech green and environmentally friendly regenerated cellulose fiber launched by Austrian Ley Lenzing Company. Its super moisture absorption performance, the unique luster of silk products and its strength superior to viscose, the fabric woven from its blended yarn with bamboo fiber can not only improve the grade of finished clothing, but also make the fabric more durable. Moisture absorption and air permeability are further improved.

[0029] Yarn used for this fabric: 40 S , bamboo fiber 70%, MODAL 30% blended yarn, and participate in weaving with DuPont Lycra silk. Processing condition is with embodiment 1.

Abstract

The present invention relates to one kind of bamboo fiber knitting fabric with blended bamboo fiber yarn as facing layer and spandex or chinlon yarn covered with the bamboo fiber. It features that the blended bamboo fiber yarn consists of bamboo fiber in 50-70 wt% and cotton, Modal, Tencel, wool, cashmere or Dacron in 30-50 wt%, and has count of 20-60 s and twist multiplier of 330-345. The bamboo fiber knitting fabric has the excellent performance of bamboo, including moisture absorption, permeation, health care and antibiotic property, etc. as well as improved costume performance and size stability, and is one kind of high grade comfortable material for underwear.

Description

technical field [0001] The invention relates to a bamboo fiber knitted fabric which uses bamboo fiber blended yarn as the surface and spandex or other yarns as the inner layer to cover the tissue. Background technique [0002] Bamboo fiber, as the name suggests, its basic raw material comes from the evergreen plant bamboo in nature. It is another regenerated green cellulose fiber after the successful development of soybean protein fiber in my country. Jilin Chemical Fiber Group Hebei Jigao Chemical Fiber Co., Ltd. took the lead in developing bamboo pulp fiber - Tianzhu, and obtained the national invention patent "Technology for Producing Viscose Fiber Pulp from Bamboo". Bamboo fiber has hygroscopicity, air permeability and drapability. It is superior to cotton fabrics, and more importantly, it has natural antibacterial properties. The same amount of bacteria is observed under a microscope, and the bacteria on cotton products do not change, while the bacteria on bamboo fibers...
