A fleece fabric

Abstract

A fleece fabric is disclosed, in which the pile side of a double-sided weave is knitted using a fleece process to form a pile layer. The double-sided weave is formed by double-needle knitting using an upper needle plate and a lower needle cylinder, with a six-way cycle. The first and sixth courses use face yarn; the second and fifth courses use middle yarn; and the third and sixth courses use base yarn. The face yarn is made of cotton yarn, the middle yarn is spandex-covered yarn with a twist of 400-500 T / m, and the base yarn is polyester DTY yarn. The double-sided weave is obtained through a combination of cotton yarn, spandex-covered yarn, and polyester DTY yarn, woven in a six-way cycle. The fleece process then produces a finished fabric with a pile layer, meeting the requirements for moisture-wicking functionality. The production of this finished fabric eliminates the padding process, saving energy and reducing emissions, thus offering environmental benefits.

Description

Technical Field

[0001] This utility model patent relates to the field of knitted fabric technology, and in particular to a fleece fabric. Background Technology

[0002] To meet the functional requirements of moisture wicking, conventional fleece fabrics often undergo a padding process, where moisture-wicking agents are adsorbed onto the fabric to impart moisture-wicking properties. However, this padding process increases energy consumption in the production process and is not conducive to green production. Therefore, we need to develop a fleece fabric that achieves moisture wicking without the padding process. Utility Model Content

[0003] The purpose of this utility model is to solve the existing technical problems by proposing a fleece fabric.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a fleece fabric comprising a double-sided structure formed by knitting face yarn, middle yarn, and base yarn, wherein the fleece surface of the double-sided structure is formed into a pile layer by a fleece process; the double-sided structure is formed by knitting with a double-needle track upper needle plate and lower needle cylinder, the double-sided structure having a six-way cycle, the first and sixth ways both using face yarn, the first and fourth ways being a knitted structure, a knitted structure, a float structure, and a float structure; the second and fifth ways both using middle yarn... The yarn has the following patterns in sequence: the second yarn consists of float weave, tuck weave, loop weave, and float weave; the fifth yarn consists of tuck weave, float weave, float weave, and loop weave; the third and sixth yarns both use base yarn, with the third yarn consisting of float weave, float weave, float weave, loop weave, and loop weave; the sixth yarn consists of float weave, float weave, loop weave, and float weave; the face yarn is cotton yarn, the middle yarn is spandex-covered yarn with a twist of 400-500T / m; and the base yarn is polyester DTY yarn.

[0005] Preferably, the spandex-covered yarn is a mechanically covered yarn formed by covering 30D spandex with 75D polyester, and the spandex in the spandex-covered yarn has a draw ratio of 3-5 times.

[0006] Preferably, the length of the intermediate yarn is 32.5cm / 100N.

[0007] Preferably, the cotton yarn is 40S Siro compact spun yarn.

[0008] Preferably, the yarn length of the veil is 37cm / 100N.

[0009] Preferably, the polyester DTY yarn is 100D / 144F polyester semi-dull lightweight mesh DTY yarn.

[0010] Preferably, the length of the base yarn is 24cm / 100N.

[0011] The beneficial effects of this utility model are: by combining cotton yarn, spandex covered yarn and polyester DTY yarn, a double-sided structure is obtained through six-way circular weaving. The double-sided structure can be processed by fleece to obtain a finished fabric with a fleece layer. The finished fabric meets the requirements of moisture absorption and perspiration wicking. The production of the finished fabric eliminates the padding process, which saves energy and reduces emissions, and has environmental benefits. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] In conjunction with the embodiments and appendices Figure 1 A fleece fabric comprising a double-sided structure formed by knitting face yarn A, middle yarn B, and base yarn C, wherein the napped side of the double-sided structure is formed into a fleece layer by a fleece process; the double-sided structure is knitted by a double-needle bed and a double-needle cylinder, and the double-sided structure is in a six-way cycle, with the first and sixth ways using face yarn, and the first and fourth ways being a loop structure, a loop structure, a float structure, and a float structure; the second and fifth ways using middle yarn, with the second way being a float structure, a loop structure, a loop structure, and a float structure, and the fifth way being a loop structure, a float structure, a float structure, and a loop structure; the third and sixth ways using base yarn, with the third way being a float structure, a float structure, a float structure, a loop structure, and a loop structure, and the sixth way being a float structure, a loop structure, and a float structure; the face yarn is cotton yarn, the middle yarn is spandex-covered yarn with a twist of 400-500T / m, and the base yarn is polyester DTY yarn. The selection of raw materials for face yarn, middle yarn, and base yarn effectively enhances the elasticity of the fabric. The double-sided structure obtained through six-way cyclic weaving maintains good fabric surface flatness and uneven fabric bottom characteristics.

[0015] A fleece fabric, wherein the spandex-covered yarn is a mechanically covered yarn formed by covering 30D spandex with 75D polyester, and the spandex in the spandex-covered yarn has a draft ratio of 3-5 times; the length of the intermediate yarn is 32.5cm / 100N, and the number of yarns fed is 1.

[0016] Furthermore, the 30D spandex yarn in the spandex-covered yarn has a length of 17cm / 100N.

[0017] The cotton yarn is 40S combed cotton Siro compact spun yarn; the yarn length of the face yarn is 37cm / 100N, and the number of yarns fed is 1.

[0018] The polyester DTY yarn is 100D / 144F polyester semi-dull lightweight mesh DTY yarn; the base yarn length is 24cm / 100N, and the number of yarns fed is 2.

[0019] By designing differentiated yarn lengths, the density of the double-sided fabric is improved, allowing the double-sided fabric to maintain tension balance between the face and bottom after dyeing and finishing shrinkage, thus reducing the risk of wrinkling of the finished fabric base.

[0020] A fleece fabric, wherein the fleece process includes a single fleece application and a double fleece application.

[0021] Furthermore, the first fleece application can be performed before the dyeing process. This first fleece application involves applying a base fleece treatment to the napped side of the double-sided fabric. The first fleece application helps the loops on the napped side better absorb the fleece agent during the subsequent softening stage, enhancing the effect of the second fleece application. Simultaneously, it reduces damage to the loop yarns from the second fleece application, maintaining good elasticity in the finished fabric. The second fleece application can be performed after the dyeing process. The thickness of the pile layer after the second fleece application is 2.5-3.5 mm. After further combing, the pile layer thickness is 2-3 mm. The finished fabric is then set. The finished fabric was tested according to GB / T 21655.2-2019, Dynamic Moisture Transfer Method, and the test results are shown in Table 1.
