Problems solved by technology

However, acrylic blended fabrics are rarely used in the field of wide-width bedding and home textiles. Part of the reason is that the actual cost of acrylic blended fabrics is relatively high due to the high consumption of wide-width bedding fabrics. The fabric has internal indicators such as anti-pilling, dyeing, and strong damage that are not up to standard
[0003] Patent CN109208135 A "Weaving method of polyester and heating acrylic fiber interweaving home textile fabric", the invention interweaves cationic dyeable polyester yarn and heating acrylic fiber yarn, and makes full use of existing fibers to weave new fabrics through the improvement of process methods. The invention does not clearly provide the influence of the detailed technical parameters of spinning and dyeing and finishing on the performance of the fabric, and does not disclose the technical means of how to improve the anti-pilling performance of the fabric and what test method is used; in actual operation, the spinning of the fabric The yarn method, tightness, and yarn specifications also have a great influence on the pilling resistance of the finished fabric. When the fabric is woven according to the shape of the honeycomb structure described in the patent, it will be more likely to cause pilling and cause its performance to deteriorate ; Patent CN109235072A "cotton acrylic fiber parallel line wide-width sanding woven fabric and production method thereof", this invention discloses the jigger production technology of dyeing acrylic fiber with disperse cationic dyes and the cotton acrylic fiber parallel line wide width woven fabric sanding production technology, The width of the fabric is very wide, and the actual cost is relatively high, which is not conducive to wide application

Abstract

The invention discloses a viscose acrylic fiber home textile fabric and a preparation method thereof. The fabric is prepared from viscose acrylic fiber blended yarn; and the viscose acrylic fiber blended yarn is composed of acrylic fibers and viscose fibers, wherein the ratio of the viscose fibers to the acrylic fibers is (80-60): (20-40). The preparation method of the viscose acrylic fiber home textile fabric comprises a spinning process, a weaving process and a dyeing and finishing process, wherein the dyeing and finishing process comprises pretreatment, dyeing and after-finishing; and a double-frequency-conversion flat cylinder dyeing machine is adopted as dyeing equipment. The viscose acrylic fiber home textile fabric is thick in hand feeling, short and dense in fluff, small in head and tail color difference and uniform in color; the dyeing and finishing processing method is relatively low in cost; and all inherent indexes of the fabric are qualified, and particularly the fabric is good in pilling resistance (circular track D method), shrinkage rate and linting rate.

Description

technical field [0001] The invention relates to a viscose acrylic fiber home textile fabric and a preparation method thereof. Background technique [0002] Acrylic fiber has always been known as artificial wool, and its soft and fluffy feel is used in clothing, carpets and other fields. Acrylic fiber can be blended with a variety of fibers, such as acrylic fiber can be blended with cotton fiber, modal, tencel, viscose, wool, polyester, nylon and other fibers with multi-component fibers to obtain different feel and style. Narrow-width knitted garment fabrics such as acrylic modal and acrylic viscose cotton are widely used in the market at present. However, acrylic blended fabrics are rarely used in the field of wide-width bedding and home textiles. Part of the reason is that the actual cost of acrylic blended fabrics is relatively high due to the high consumption of wide-width bedding fabrics. The fabric has internal indicators such as anti-pilling, dyeing, and strong damag...
